Primary health care (Puskesmas) is a core component of health systems [1]. Based on the Alma Ata Declaration in 1978, Puskesmas is defined as essential health care that meets the needs of communities, is easy to access, acceptable, and affordable [2]. The declaration combined 3 elements considered core to delivering sustainable and equitable health services: multisectoral public policy, empowered communities, and primary public health care [2,3].

In 2022, the Ministry of Health (MoH) of the Republic of Indonesia launched its health system transformation strategy. There are 6 pillars of the transformation strategy, and one of them is primary health care (PHC) transformation, which in its implementation focuses on strengthening promotive and preventive activities to create more healthy people, improve health screening, and increase primary service capacity. The number of Puskesmas has increased since 2017, from 9825 units to 10,374 Puskesmas in 2022. The ratio of Puskesmas in Indonesia to subdistricts in 2022 is 1.4. This illustrates that the ideal ratio of Puskesmas to subdistricts, namely a minimum of 1 Puskesmas in 1 subdistrict, has been fulfilled nationally. In terms of an average ratio, each Puskesmas serves 27,000‐30,000 residents in 2023. What needs to be considered is the distribution of the Puskesmas in all subdistricts, especially in remote, frontier, and outermost areas to provide public health services to households with a focus on maternal and child health services, elderly health, communicable disease, and noncommunicable disease prevention [4].

Puskesmas in Indonesia spread across all types of characteristic regions such as urban, rural, remote, and very remote in Indonesia within all 38 provinces and 514 districts or cities. In Indonesia, there are two main functions of Puskesmas: (1) provide an integrated individual health care that includes the activity and a series of basic individual medical services to improve the individual health, preventing and curing disease, and (2) provide essential public health services to the community, including health promotion, maternal and child health, nutrition, disease prevention and control, and environmental health. Puskesmas in Indonesia also has a responsibility to carry out technical guidance to clinics and other community health services as the Puskesmas networking partner institutions in the area. Other tasks of Puskesmas are to provide continuous and comprehensive care, to refer to specialists and hospital services, to coordinate health services, to guide the patient within the network of public health services, and to provide the best possible health services [5].

One of the elements that support health care services is IT. In the era of digital, Internet of Things, and artificial intelligence (AI), the digital transformation in health care also increases expectations of the quality of care [6]. Since the COVID-19 pandemic, digital information from the internet has gained importance in all areas of life. This trend was already evident before the COVID-19 pandemic. However, it accelerated this development and is also reflected in the health care sector [7]. With the widespread use of smartphones, downloadable or internet-based apps will play a major role in the diagnosis of diseases and monitoring and management of patients.

Technology and internet connection have played a significant role in bridging the gaps of health access and equity toward all individuals amid the geographic and socioeconomic challenges. In Indonesia’s decentralized health care system, Puskesmas are mandated to deliver not only curative services but also promotive, preventive, and administrative functions, particularly within the framework of the national health insurance program (Jaminan Kesehatan Nasional). Achieving these responsibilities requires functional coordination across various health system components, many of which increasingly depend on stable internet connectivity.

Internet access supports critical digital infrastructure for public health surveillance, insurance claims, medicine supply chain management, and national health program reporting. For example, real-time reporting through the Sistem Kewaspadaan Dini dan Respon and Sistem Informasi Malaria enables early detection and response to disease outbreaks—a crucial function in archipelagic and remote regions where delayed reporting can lead to localized epidemics [8]. Similarly, routine reporting on immunization services and noncommunicable disease screenings is now conducted through the Aplikasi Sehat IndonesiaKu, a digital platform mandated by the MoH for primary care reporting and national dashboard integration [9].

In addition, internet connectivity is required to operate pharmaceutical inventory management tools, such as e-Logistik, which help prevent medicine stockouts—one of the persistent challenges in rural and remote areas [10]. The national Cek Kesehatan Gratis campaign, a government-initiated free screening program for all Indonesian population, also requires digital reporting systems for real-time coverage tracking and participant data documentation [11]. Administrative functions, particularly processing health care claims via Indonesia Case-Based Groups under Badan Penyelenggara Jaminan Sosial Kesehatan, are highly dependent on reliable internet access to ensure service reimbursement and continuity [12]. Moreover, in the absence of specialist doctors in many rural settings, internet-based coordination with referral hospitals has become a crucial alternative for maintaining continuity of care. More recently, the implementation of the SATUSEHAT (ie, Satu Data Kesehatan) platform by the Ministry of Health requires Puskesmas to connect their electronic medical record (EMR) systems to a national health data exchange ecosystem, making stable internet access a prerequisite for full participation in Indonesia’s digital health integration efforts [13].

At the PHC level, internet connection has been a very critical infrastructure to support health data recording and reporting through a health information system, which is rooted from a routine data collection and serves as health indicators for government evaluations. These health data are critical to be disseminated to the health officials as evidence for program planning, and also to inform the patients related to immunization schedule, visit reminder, laboratory referrals, and other activities related to patients' follow-up [14].

Indonesia is the world’s fourth most populous country with more than 270 million people residing across more than 17,000 islands [15,16]. As an archipelagic country, this condition results in disadvantages in terms of information and communication technology (ICT) infrastructure [17]. In addition, almost all internet users in Indonesia connect through mobile devices. Although mobile broadband (3G, but now increasingly 4G/LTE) is the most widely used internet service in Indonesia, it is not at par with fixed broadband with respect to capacity, quality of service, high bandwidth performance, and cost-efficiency. Such limited access to high-quality internet prevents the population from unlocking its productive capabilities to fully reap the benefits of a digital economy and points to two key challenges: how to make fixed broadband internet access universal and increase internet quality. Increased optical fiber network coverage is a necessary but insufficient solution to meeting the key challenges. While investment by private service providers, along with government projects such as Palapa Ring, has steadily increased connectivity and service availability across Indonesian districts, internet subscriptions have not increased in parallel. Only 26% of homes with access to a fixed broadband provider subscribe to this service [18].

Several studies on IT infrastructure supporting health information systems in health care facilities have been conducted in Indonesia and other countries [19-21]. However, there is no detailed information available that can describe the accessibility and quality of the internet at Public Health Centers (Puskesmas) in Indonesia. This paper aims to provide, for the first time, a comprehensive overview of internet availability and connection reliability, as well as supporting IT infrastructure across Puskesmas throughout the country. While reliable internet connectivity is increasingly recognized as a foundational enabler for digital health transformation—including telemedicine, electronic health records, digital logistics, and surveillance systems—this study does not assess the direct impact of internet infrastructure on health care delivery or patient outcomes. Instead, it offers a baseline mapping of digital connectivity conditions to identify geographic disparities and inform future investments needed to enhance digital readiness in Indonesia’s primary care system.

The internet’s significant role in aiding public health services is undeniable. This paper marks the first comprehensive depiction of the accessibility and quality of internet connections and computer systems across Indonesia’s Puskesmas, providing crucial insights into the information technology infrastructure. The internet availability in the health facility is highly crucial to foster the delivery of healthcare among communities [28,29]. By presenting baseline data on internet quality across Puskesmas, this study contributes foundational insights to support future efforts aimed at strengthening health information systems and expanding the digital infrastructure needed for more equitable and efficient PHC delivery in Indonesia.

Indonesia presents a particularly interesting case when it comes to internet connectivity and accessibility to health care services, especially in the context of health care digitization [30]. In numerous instances, technological advancements have the potential to significantly reduce health care inequalities. Furthermore, digital health is recognized as a valuable technological approach that can effectively bridge the significant gap between urban and rural populations [31] and between high-income and low- and middle-income countries (LMIC) [32].

One way of improving health care service delivery is through adoption of broadband Internet access [33]. In the health system, service delivery refers to where patients receive the treatment as well as supplies entitled. Broadband internet access helps to reshape many health-related processes and supports effective treatment of patients [33]. It helps medics to provide patients with faster diagnosis to their respective health conditions, the development of treatment plans, making patient records as well as test results accessible by patients from the examination room, facilitates faster consultation electronically on treatment plans, helps patients and their attendants access practice guidelines faster [15,34,35], and led to the adoption of telehealth technologies which has contributed to easy access to health services [36]. The availability of Internet access, coupled with the accelerated adoption of eHealth and mHealth platforms and the rapid evolution of digital technology access, has generated a significant opportunity to enhance the reach, quality, and efficiency of PHC service delivery, thereby facilitating the achievement of universal health coverage [37].

According to this study, it was found that 78.4% (8,143/10,378) of Puskesmas have good and sufficient internet quality, 14.4% (1,490/10,378) Puskesmas have insufficient internet connection, and 7.2% (745/10,378) of the Puskesmas do not have internet access at all. The study depicts that the eastern part of Indonesia had the least internet connection in Puskesmas compared to other parts of Indonesia, which includes Maluku and Papua regions. This is aligned with previous findings related to the limited internet access in the eastern part of Indonesia and low ICT development index in 2020‐2021 throughout the areas [38-41]. The ICT Development Index, published by the United Nations International Telecommunication Union, serves as a crucial benchmarking tool for measuring the information society by utilizing internationally agreed ICT indicators, assisting governments, operators, development agencies, researchers, and others in assessing the digital divide and comparing ICT performance globally [42]. Poor internet connectivity is one of the barriers to implementing telehealth [43]. Studies reveal varying rates of internet connection across different countries affect the adoption and implementation of telehealth and eHealth [44,45]; and digital health initiatives, especially in rural areas [46]. The underlying causes of limited internet access in the eastern part of Indonesia may be due to several aspects, including challenging geography, archipelagic region, size of territory to cover, limited infrastructure, which should be taken into account as barriers that limit the accesses [47-49]. High service costs to provide IT infrastructure (including tower, fiber optic, etc) have become the challenge to evenly provide internet access across the country, especially in remote areas [50]. While at the same time, the user also finds it a burden to subscribe to the certain internet monthly fee [51-53]. Some studies also showed that sociobehavioral values and perceptions toward digitalization also influence enhancing or limiting the internet availability, including unwillingness of the local people to allow the internet infrastructure development, lower education attainment, and low adult literacy [52,54].

For completing administrative tasks in Puskesmas, such as browsing, data input, upload and download files, or to support any other health service tasks, according to information and technology literatures, it requires a minimum specification of 4 GB RAM and CPU i3 or above for computer or laptop to perform basic data management (input/edit/delete data or simple online browsing) [55,56]. These findings show that the majority (60.70%, 61,390/101,140) of the Puskesmas in Indonesia already had 4 GB RAM or above in their computers, while 18.34% (18,546/101,140) of them were lower (2 GB and 1 GB). As for the CPU specification, 83% (83,970/101,140) of the Puskesmas had the sufficient CPU specification (i3 type or above), while 17% (17,170/101,140) of them had insufficient, which were Celeron and Core2. It is understood higher RAM capacity and newest CPU specifications are linked with better computer performance, which is highly important to be provided in Puskesmas to ensure smooth operation of critical health care software, efficient management of electronic health records, and reliable services, ultimately supporting effective patient care delivery in the health care facilities [57,58].

Although CPU, RAM, and memory do not directly control bandwidth or download speeds, they significantly influence the user’s ability to use the internet efficiently for digital health service. The CPU determines how quickly a computer can process incoming data from the internet, execute scripts, and render web pages. A slower CPU may lead to delays in page loading, application responsiveness, and user interaction, particularly with web-based health information systems. Goel et al [59] demonstrated that lowering CPU performance (eg, through power-saving modes on Android devices) results in slower page loading and degraded user experience in accessing online resources. Similarly, another study notes that a slow processor can act as a bottleneck when decoding or rendering content received over the internet, making the browsing experience sluggish [60]. RAM enables systems to temporarily store and quickly access active data. Systems with insufficient RAM often struggle when running multiple applications or browser tabs, leading to frequent slowdowns or crashes. This affects the usability of internet-dependent applications, especially in environments such as health centers where simultaneous tasks are common. While RAM does not increase raw internet speed, having adequate memory ensures smoother browser and application performance [61]. Another report supports this by showing that memory capacity and technology trends directly influence web system performance and throughput [62].

Similarly, with RAM capacity and processors, hard disk was also found to affect the computer’s capacity to process [58]. This study reveals that the majority of Puskesmas have a sufficient hard disk of 256 GB or above (88%, 20,932/100,510), and 12% (12,240/100,510) of them have an insufficient one (128 GB). Literature findings show that 128 GB internal storage is able to undergo basic operations; however, it will demand higher capacity for extensive computer use [63]. The hard disk is crucial for computer performance as it stores and retrieves data, including the operating system and applications, facilitating efficient multitasking and overall system responsiveness [57,58].

Across various low- and middle-income countries, the results consistently highlight significant disparities in hardware infrastructure at the PHC level, which directly impact the implementation of digital health systems [64]. In Nigeria, many PHC centers still rely on desktop computers with only 512 MB to 2 GB of RAM and outdated Pentium IV processors, limiting their ability to run modern eHealth applications [65]. Similarly, in Uganda, facilities were found using laptops with 1 GB RAM and low-speed CPUs, which caused frequent delays and hindered real-time data entry and synchronization [66]. In Kenya, a study revealed that more than half of the PHC sites were equipped with low-specification devices using Intel Atom processors and 2 GB RAM, often unable to handle multiple web-based platforms simultaneously [67]. In parts of Latin America, such as Peru and Bolivia, rural clinics were reported to operate with refurbished computers having less than 2 GB RAM, rendering them incompatible with many EMR systems [68]. These findings underscore the urgent need for targeted investment in basic digital infrastructure to ensure the successful adoption of health information systems in resource-constrained settings [69].

As for the antivirus, this finding shows that the coverage of antivirus installation in Puskesmas’ computers is still incomplete, especially in DKI Jakarta, Banten, and West Java provinces, which leave almost half of its Puskesmas unprotected with the antivirus. In health care facilities, malware protection is critical for computer performance as it safeguards sensitive patient data, prevents potential cyberattacks, and ensures the uninterrupted operation of vital medical software, maintaining the integrity and security of patient care services [70,71]. Several studies have highlighted the limited implementation of antivirus software and weak cybersecurity practices in PHC facilities across LMICs. Hasegawa et al [72] conducted a scoping review and found that antivirus installation in PHC settings was often inconsistent or absent due to limited funding, lack of technical support, and absence of standardized cybersecurity policies. Similarly, the World Health Organization (2021) reported that many LMIC PHCs do not regularly update or install antivirus software, making them vulnerable to malware and data breaches [73]. A scoping review study by He et al [74] found that one of the major challenges of healthcare cybersecurity is the lack of security awareness. Collectively, these findings underscore the urgent need for national digital health policies that mandate and support sustainable cybersecurity infrastructure, including antivirus software, within PHC systems across LMICs.

This study found that 8.02% (832/10,378) of Puskesmas in Indonesia have no access to electricity for 24 hours. Most provinces that did not have access to 24-hour electricity were located in the eastern part of Indonesia, such as Maluku and Papua island. Modern energy enables health service delivery. Access to electricity is, however, unreliable in many health facilities in developing countries [75]. Reliable basic infrastructure, particularly electricity, is a critical enabling factor in improving health systems [76]. Previous literature showed that the availability of electricity is an important determinant of receiving health information and use of health services [77,78]. Based on a literature study conducted in developing countries [65,], there are many barriers that can occur during the electricity provision across the nation, this includes the lack of IT infrastructure, especially electricity supply. Indonesia started the rural electrification program in the late 1950s, but how to provide electricity in a sustainable way both organizationally and institutionally still becomes a big challenge [79]. According to the World Health Organization (2023), nearly 1 billion people globally are served by health care facilities that either lack electricity altogether or rely on highly unreliable sources, with PHC centers being especially affected [78]. A systematic review by Ibrahim et al [80] found that fewer than 30% of PHC facilities in LMICs had consistent electricity access, which severely undermines the ability to store vaccines, operate diagnostic equipment, and provide emergency care [80]. In a multicountry study of surgical hospitals across 21 LMICs, continuous electricity availability was reported in less than two-thirds of facilities, with countries such as Sierra Leone and Malawi experiencing 0% reliable power supply [81]. These power gaps directly limit the deployment of digital health technologies, vaccine cold chains, and essential services. According to the Electricity Power Supply Business Plan 2019‐2028, Indonesia’s average electricity growth is at 6.42%. Indonesia successfully surpassed its electrification ratio target at the end of the year 2018 [81]. However, there are still 2510 villages across Indonesia that are not yet electrified [82]. Increasing the electrification ratio always becomes a challenging task because Indonesia has many islands, and many communities are isolated from one another [79]. This geographical situation also worsens with poor infrastructure access, making the area hard to reach [83]. There are several fundamental requirements that need to be implemented in order to cope with the rural electrification challenges [84-86]. The lessons learned from other countries that have successfully achieved universal electricity access were summarized in several studies [87]. Committed governance and supportive regulations and policies are one of the most often stated in the literature [87]. Moreover, a collaboration of appropriate policies and government will increase the private sector’s participation in the rural electrification program [88].

Based on this study and consultation with experts, it is recommended that Puskesmas facilities in Indonesia require a minimum internet bandwidth of 10 to 20 Mbps. This range is deemed as a minimum essential requirement to ensure reliable access to digital resources and the efficient input of patient EMR data. In addition, PHC services should be equipped with at least Intel Core i3 processors, 8 GB RAM, and 256 GB solid-state drive storage to enable smooth operation of digital applications and web-based platforms [69]. Optimal performance, especially in urban or high-volume facilities, may require upgrading to Intel Core i5 processors and 16 GB RAM, which align with the performance needs of multitasking systems and real-time data entry [67,68]. This study provides a structured and evidence-based framework for assessing internet quality in PHC facilities, which is especially relevant for benchmarking across comparable middle-income countries. Many countries with similar socioeconomic and infrastructural conditions face shared challenges in ensuring reliable digital connectivity in remote or underserved health centers [89,90]. By developing and validating a weighted, multi-indicator scoring system, grounded in technical, infrastructural, and operational factors, this study offers a replicable model that can inform digital health readiness assessments beyond Indonesia. Such benchmarking tools are essential as countries pursue universal health coverage and integrate eHealth systems in alignment with the World Health Organization’s Global Strategy on Digital Health 2020‐2025. Additionally, initiatives like the International Telecommunication Union and the World Bank’s Digital Economy for Africa and Asia programs emphasize the need for context-sensitive indicators to guide investments in health ICT infrastructure [91,92]. Therefore, this study not only addresses a national implementation gap but also contributes to the global evidence base supporting digital health infrastructure development in resource-constrained settings.

Successful implementation, rollout, and use of the digital system require PHC facilities to be equipped with appropriate digital and data infrastructure. In Tanzania, as part of the National PHC Rolling Digital Transformation Roadmap, service delivery points for in-facility continuity of care are using a LAN that is installed within facilities [93]. While interfacility referrals and integration with public domain systems. While in China, in order to guide the development of internet health care, the Chinese government has issued a series of regulations and guidelines. The State Council of the People’s Republic of China has issued the Guidance on Actively Promoting the Action of “Internet Plus.” It proposed to develop internet-based health care services, encourage internet enterprises to cooperate with medical institutions for establishing medical network information platforms, reinforce the integration of regional health care resources, and actively apply the mobile internet to explore and provide health services [94]. Depending on the different initiators, there are 3 main modes of internet health care service provision in mainland China: hospital-led, government-led, and enterprise-led internet healthcare platforms [95].

This research exhibits several strengths that contribute to its significance in the field. The study at hand is a groundbreaking research effort that has comprehensively assessed a wide range of internet components in PHC facilities, including device availability, access, and internet quality in nearly all public health centers across Indonesia. The findings of this study provide valuable insights into various supporting factors that can facilitate the implementation of IT transformation. The study highlights the significance of the availability, quality, barriers of computer systems, hardware, and software devices, which can serve as instrumental inputs for the government in their decision-making processes regarding the implementation of such transformations.

However, certain limitations must be acknowledged: (1) Bandwidth checks to assess the quality of internet access were only carried out in the morning and evening, which depends on local conditions and the respondent’s honesty; (2) the completeness of filling out the questionnaire was influenced by the capacity of the assigned respondents; (3) validation of CPU, RAM, and antivirus could not be done directly; (4) potential selection bias may occur as we performed the assessment using an online survey, although we have minimized this bias by having coordination with the designated Public Health Governance team MoH and district or Provincial Health Offices allowing them to complete the survey within a 2-month period, having offline coordination to ensure we obtained survey feedback from Puskesmas. Nevertheless, this study provides a deeper overview of the access and barriers of internet access and other supporting IT infrastructure in 10,378 public health centers throughout Indonesia.

The internet plays a vital role in health care services, facilitating communication, information exchange, and access to medical resources. Despite the fact that 78% of health care centers in Indonesia have sufficient internet connectivity, challenges persist, with some areas experiencing limited access or complete absence of internet connectivity. To ensure universal availability of the internet across primary care services in Indonesia, additional measures are imperative. This study demonstrates the need for collaborative actions among government, health care workers, and telecom providers to allocate a supportive budget for sustainable internet infrastructure, including satellite-based internet services that enable strong internet connection in remote, underserved, and digitally excluded regions. Technology infrastructure should also follow, including high-quality computer systems with adequate specifications to handle health care–related tasks efficiently, as well as ensuring uninterrupted 24-hour access to electrical power to support continuous internet connectivity and operational efficiency in health care facilities. Future studies are encouraged to explore the relationship between internet quality and health care service delivery outcomes to better understand its operational impact. Additionally, longitudinal assessments could help monitor improvements over time and guide digital infrastructure investments in public health systems. Although this study does not assess clinical performance or health care outcomes, it provides crucial baseline evidence on digital infrastructure status. These insights can help guide targeted investments and future evaluations as Indonesia advances toward nationwide digital health integration.
