Environmental pollution is a common problem in cities and can increase the likelihood of flooding. The purpose of this study is to analyze environmental pollution as a cause of flooding in the Pekapuran Street area, Depok City. This study applies a descriptive method with a qualitative approach. Data were obtained through observation, documentation, and literature review. Based on the results of the study, it was found that the accumulation of household waste around the drainage channels causes obstruction of water flow, which triggers flooding during rain. In addition, the shallow, mud-filled, and poorly maintained drainage conditions increase the risk of flooding. Low levels of public awareness of environmental cleanliness are also factors that exacerbate the condition. This study concludes that flooding on Pekapuran Street is influenced not only by high rainfall, but also by environmental pollution and a suboptimal drainage system. Based on this, better waste management and drainage maintenance are needed to minimize the risk of flooding in the area.

This study aims to identify the management system for Taman Imbi by the Department of Public Works and Public Housing (Dinas PUPR) and to analyze its comfort level based on the perceptions of park visitors and street vendors (PKL). Taman Imbi, managed by the PUPR Service (Section for Environmental Management and Parks), is one of the main urban parks in the city center of North Jayapura District. The research uses a descriptive, qualitative approach combined with Likert-scale analysis. Primary data were obtained from questionnaires distributed to 100 park visitors and 10 business actors (PKL) operating around the park. Eight comfort indicators were assessed, based on Hakim (2003): aesthetics, cleanliness, safety, noise, circulation, aroma, physical form, and climate/natural forces. Results indicate that, based on visitor perceptions, the overall comfort level was 56.0% (fairly good), while PKL perceptions were 64.4% (good). Among all indicators, circulation scored the lowest for visitors (46.2%), particularly ease of access. Aroma/odor scored the highest for PKL (80.0%). The study recommends rehabilitating park facilities, reactivating security posts, improving pedestrian and parking access, and clarifying spatial zoning for economic and community activities in the park.

Street names are a vital public information tool that helps people identify locations, find addresses, and reinforce the identity of a region. The availability of street names also supports the effectiveness of administrative services, community mobility, and emergency service access. Srigonco Village, Bantur District, Malang Regency, still faces a lack of street names, making it difficult for residents and visitors to find specific addresses. Based on this situation, students from the 14th Community Service Program (KKN-T) at Raden Rahmat Islamic University (Unira) Malang implemented a community service program involving mapping and installing street names at several strategic locations in the village. The implementation method included field observation, street name data collection, coordination with village officials, design and production, and installation of the street names. This program aims to improve access to location information, clarify regional identity, and support orderly village administration. The results of the activity indicate that the presence of street names provides tangible benefits to the community, particularly in facilitating address searches, improving environmental order, and helping visitors to identify Srigonco Village more easily and effectively.

The increasing demand for electrical energy in military education facilities necessitates an efficient, reliable, and sustainable energy solution. This research aims to design a Solar Power Plant (PLTS) system to meet the street lighting needs in the Wangi-Wangi Complex of the Indonesian Naval Academy (AAL). The research method used is quantitative descriptive with an engineering design approach thru the stages of site survey, collection of solar energy potential data in the Surabaya area, calculation of electricity energy needs, calculation of solar panel capacity, calculation of battery capacity, and design of battery connection configuration. The research results show that the energy requirement for street lighting is 1,920 Wh/day, sourced from 8 units of 20 Watt LED lamps with an operating time of 12 hours per day. Based on the average solar radiation potential in Surabaya of 5 kWh/m²/day, the designed system requires 3 units of 200 Wp monocrystalline solar panels with a total area of approximately 4.89 m². For energy storage, 4 units of Yuasa N200 12 V 200 Ah batteries are used, configured in a series-parallel arrangement, capable of providing an effective energy of around 3,600 Wh with an estimated operating time of 22.5 hours. The research results indicate that the proposed solar power plant design is feasible to implement as an environmentally friendly, efficient alternative energy source that supports the green defense concept in the AAL environment.

The observation of guidance and counseling activities was conducted at SDN 2 Pasaleman, located in Pasaleman Village, Kresna Street, Dusun Pon. This study aimed to identify the problems faced by students and to examine the role of teachers in implementing guidance and counseling services at the elementary school level. Data were collected through direct observation in the school environment and interviews with homeroom teachers. The results indicated several student-related issues, including verbal bullying such as teasing, low learning motivation, fighting behavior among lower-grade students, and a tendency to skip school among upper-grade students. These issues were influenced by peer environments, limited supervision, and low awareness of the importance of education. Teachers have made various efforts, including providing guidance, applying individual approaches, and maintaining communication with parents. Additionally, character values are integrated into daily learning activities. In general, guidance and counseling services have been implemented, but further improvement in more systematic strategies and broader support is still required.

This research is motivated by the complex problems of street children, vagrants, and beggars in Jambi City, which are influenced by poverty, urbanization, and weak social protection. This phenomenon not only impacts public order but also reflects the suboptimal social welfare system at the regional level. Although local governments have implemented various policies through social order and rehabilitation approaches, their effectiveness still faces various structural and cultural challenges. This study uses Bryson's Policy Implementation Mapping theoretical framework, which includes indicators of interests, resources, channels, potential participation, level of influence, implications, and actions as the main analysis. The research approach used is a qualitative case study design to understand the dynamics of policy implementation in depth. Data collection techniques were carried out through in-depth interviews, participant observation, and documentation, with informants selected using purposive sampling until data saturation was achieved. The results show that policy implementation mapping has been carried out through collaboration between the Social Service and the Public Order Agency (Satpol PP) with a structured preventive, repressive, and rehabilitative approach. However, implementation has not been optimal due to limited rehabilitation facilities, lack of coordination between agencies, low community participation, and high mobility of beggars from outside the region. Furthermore, there is a gap between high administrative achievements and the reality on the ground, which still shows a high rate of returning to the streets. This study concludes that mapping policy implementation requires a more holistic, sustainable approach based on economic empowerment and strengthened cross-sectoral coordination to address this social issue more effectively and effectively.

Street vendors play an essential role in urban informal economies by fulfilling community needs and supporting local economic activity. This study analyzes the role of business ethics in building consumer trust among street vendors in Dumai, Indonesia. A qualitative descriptive method was applied using interviews, observation, and documentation involving three vendors and two consumers. Findings indicate that ethical practices such as honesty in transactions, responsibility for product quality, friendly service, and cleanliness of business premises improve consumer comfort and perceived safety. These conditions encourage repeat purchases, customer loyalty, and a positive reputation for vendors. Therefore, business ethics function not only as moral guidance but also as social capital supporting the sustainability of informal microenterprises. This study highlights that ethical behavior is crucial for strengthening long-term relationships between vendors and consumers in urban settings. Overall, implementing ethical standards contributes to sustainable small business development in informal sectors. It also improves public trust.

This study examines the effectiveness of urban city parks as a form of Urban Green Open Space (UGOS) in Jayapura City, focusing on Imbi Park (2,347.20 m²) and Mesran Park (2,122.88 m²). A mixed-methods approach combined direct observation of six park characteristics with a questionnaire-based rating-scale assessment of nineteen functional variables covering socio-cultural, aesthetic, and economic functions. Data were collected from 100 visitors and 31 street vendors, and analyzed using descriptive statistics and scoring analysis in accordance with Minister of Public Works Regulation No. 05/PRT/M/2008. Both parks share three dominant functions socio-cultural, aesthetic, and economic while the ecological function is present but not dominant. For Imbi Park, the socio-cultural function was moderately effective (1.8–2.0), aesthetic moderately effective to effective (2.4–2.6), and economic moderately effective (1.8–1.9). For Mesran Park, socio-cultural and aesthetic functions were moderately effective (1.8–2.2), while the economic function was ineffective (1.6). The main weaknesses across both parks are the unavailability of security posts and limited diversity of park-produce-based economic activities. The study recommends developing supporting facilities and a park-profile web portal to improve effectiveness and information accessibility.

Low-rank coal generally has a high moisture content, which results in a low calorific value and suboptimal quality for utilization as an energy source. One method that can be applied to improve coal quality is the Upgrading Brown Coal (UBC) process, which functions to reduce moisture content and increase fixed carbon value. This study aims to analyze the effect of heating time and the ratio of used oil composition on improving coal quality based on proximate parameters. The research method includes collecting coal samples from four locations in Samarinda and its surrounding areas, namely SMAN 1 Samarinda, Bhineka Street, Palaran Stadium, and Tani Bakti Village. The samples were analyzed using proximate analysis, including inherent moisture (IM), ash content (AC), volatile matter (VM), and fixed carbon (FC), both before and after the UBC process. The upgrading process was carried out with variations in heating time and used oil composition as a coating medium to enhance coal stability and prevent moisture reabsorption. The final results of the upgrading process showed the best values of inherent moisture at 13.64%, ash content at 4.66%, volatile matter at 55.06%, and fixed carbon at 44.94%. The results indicate that the UBC process is capable of reducing inherent moisture and increasing fixed carbon, thereby improving coal quality. Variations in heating time and used oil composition have a significant effect on changes in proximate parameters. Longer heating time and an appropriate ratio of used oil composition result in a more optimal improvement in coal quality.

This research examines the implementation of mobile public services in archipelagic contexts, where dispersed settlements, dependence on sea transportation, weather uncertainty, and limited digital connectivity significantly constrain service access and continuity. Although digital government has developed rapidly, most previous studies focus on urban or mainland settings and rarely consider geography as a determining factor. This creates a gap in understanding how archipelagic conditions interact with governmental capacity, governance structures, and frontline practices. The study aims to explain the mechanisms of mobile service implementation under these constraints and to develop an Archipelagic Implementation Framework that integrates context, capacity, governance, and outcomes. Using a qualitative single-case study approach in Raja Ampat Regency, Indonesia, data were collected through in-depth interviews, policy documents, and limited observation, then analyzed using hybrid thematic analysis. The findings reveal that archipelagic constraints lead to frequent rescheduling, hybrid online–offline service delivery, increased coordination demands, and connectivity challenges. Service sustainability depends on staff rotation, portable infrastructure, and adaptive strategies by frontline actors. The proposed framework highlights how contextual constraints shape administrative capacity, coordination, and service outcomes, offering practical insights for resilient public service delivery.

This study examines the legality of on-street parking levy practices in Kupang City from a constitutional law perspective, with a primary focus on the application of the legality principle. The background of this research stems from a significant discrepancy between the legal norms established in statutory regulations and the empirical administrative practices occurring in the field. Identified issues include the collection of levies without official tickets, the lack of clarity regarding the identity and legal status of collection officers, and the inconsistent and non-transparent application of parking tariffs. This research employs a normative-empirical legal method by applying statutory, conceptual, and empirical approaches through limited field observations. The findings indicate that although the Kupang City Government formally possesses the attribution of authority to collect parking levies, the implementation frequently deviates from the established legal procedures. Such deviant practices potentially constitute ultra vires actions and violate the principle of due process of law in government administration. This study concludes that the substantive legality of parking levies in Kupang City has not been fully realized, thereby undermining legal certainty and public trust in the legitimacy of local governance. The implications of this research emphasize the imperative for comprehensive reform of the supervision system and stricter enforcement of administrative procedures to ensure the rule of law at the local level.

This study aims to analyze the role of Islamic Religious Counselors as street-level bureaucrats in implementing Islamic Community Guidance policies in Batang Regency. The study used a mixed-methods approach with a sequential explanatory design, beginning with the collection and analysis of quantitative data and then deepening with qualitative data. Quantitative data were obtained from 53 respondents using a questionnaire that was tested for validity and reliability. In contrast, qualitative data were collected through in-depth interviews, observations, and documentation with religious counselors, Ministry of Religious Affairs officials, the KUA (Office of Religious Affairs), and the community. Data analysis was conducted descriptively and analytically using Michael Lipsky's street-level bureaucracy theory as an analytical framework. The study's results indicate that the role of Islamic Religious Extension Workers as street-level bureaucrats is positively and strongly associated with the successful implementation of the Islamic Community Guidance policy (r = 0.826; p < 0.01). Qualitative findings revealed that extension workers exercise discretion in the form of community assistance, adjustments to extension methods, strategic flexibility, and responsiveness to socio-religious issues at the local level. This study confirms that the effectiveness of Islamic Community Guidance policies is not determined solely by formal policy design but is highly dependent on the capacity, flexibility, and discretion of Islamic Religious Counselors, the implementing actors at the field level. These findings provide theoretical contributions to the development of street-level bureaucracy studies in the context of religious policy, as well as practical implications for formulating more contextual and responsive policies.

The phenomenon of homeless individuals and beggars (gepeng) in Jambi City remains a significant and ongoing social issue, indicating that efforts to address poverty and urban social vulnerability have not yet been fully effective. Although the local government, through the Jambi City Social Affairs Office, has implemented a Social Rehabilitation Program aimed at restoring beneficiaries’ social functioning through outreach, social assessment, social guidance, skills training, and family reunification, the presence of gepeng in public spaces continues to fluctuate from 2022 to 2024. This study analyzes the effectiveness of the program’s implementation, particularly the social guidance component, using a qualitative case study approach. Data were collected through in-depth interviews, field observation, and documentation review, and analyzed using George C. Edward III’s policy implementation theory, which emphasizes communication, resources, disposition, and bureaucratic structure. The findings show that the program has been carried out procedurally and humanely; however, its effectiveness remains limited due to insufficient numbers of social workers, weak and unsustained economic empowerment support, and inadequate post-rehabilitation monitoring. As a result, some beneficiaries return to the streets after completing the program. Therefore, strengthening inter-agency communication, increasing resource capacity, integrating sustainable economic empowerment initiatives, and improving consistent monitoring systems are essential steps to achieve long-term and more sustainable reductions in homelessness in Jambi.

Ramadan brings significant changes in the shopping and consumption patterns of Indonesians. There is an increase in demand for various types of food and beverages, both for sahur and iftar. The purpose of this study is to map the characteristics of food and beverage purchasing and consumption patterns in a seasonal context (Ramadan): strategic implications for UMKM in the Greater Jakarta area. The research design used is descriptive quantitative with data collection techniques implemented by distributing questionnaires. Then, the questionnaire answers are summarized to obtain the frequency distribution of each item in the questionnaire. The population of this study is people domiciled in the Greater Jakarta area. The sample size was determined using the Lameshow formula, resulting in a sample of 100 respondents spread across the Greater Jakarta area. The majority of respondents, namely 92%, stated that they experienced changes in their shopping patterns during Ramadan. The type of food purchased changed (34%) was the most dominant change. The most dominant consumption purchasing decision during Ramadan was the practicality in preparing food (40%), with favorite shopping places being traditional markets (24%) and street vendors (24%). In a consumption analysis, 83% of respondents experienced changes in their consumption patterns during Ramadan, with the most dominant change being in the amount of food consumed (29%). During sahur (pre-dawn meal), respondents tended to consume vegetables (36%) and chicken (22%). Meanwhile, fried foods (38%) and rice cakes (rice cakes) were the favorite dishes for breaking the fast.

Illegal street racing is a persistent issue in Indonesia, including Bungo Regency, endangering road users and violating traffic laws. This study, based on a case study at the Traffic Unit of Bungo Police Resort, aims to explore the police's role in addressing illegal street racing from an Islamic criminal law perspective. Using a qualitative juridical-empirical approach, the study examines legal regulations, institutional practices, and Islamic jurisprudence. Data was gathered from legal sources and literature related to law enforcement and Islamic criminal law. The results reveal that the police play a strategic role in combating street racing through preventative, preemptive, and repressive tactics. Repressive measures include law enforcement based on the Indonesian Traffic and Road Transportation Law, while preventive actions involve community outreach, traffic education, and regular patrols. From an Islamic criminal law viewpoint, illegal street racing is categorized as jarimah ta‘zīr, where authorities impose sanctions to maintain public order and prevent harm (mafsadah), aligning with the maqasid al-shariah goals of preserving property and life. The study concludes that effective and sustainable action against street racing requires collaboration between law enforcement, communities, and religious perspectives.

This study aims to analyze the discretion of family planning counselors in implementing contraceptive policies and the influence of acceptors' socio-demographic characteristics in Demak Regency. Using a mixed-methods approach with a sequential explanatory design, the study included 89 respondents for quantitative analysis and five key informants for in-depth interviews. The results showed a strong positive correlation between counselor discretion and acceptor socio-demographic characteristics (r = 0.646; p < 0.001), which explained 41.7% of the variance in discretionary practices. Counselors adapted communication strategies based on the age, education, geographic location, and culture of acceptors. Policy implementation faced obstacles in the counselor-community ratio (1:23) and the dominance of short-term contraceptive choices due to socio-cultural influences. Theoretical implications enrich the literature on street-level bureaucracy, while practical implications recommend strengthening counselors' capacity, increasing the ideal ratio, and implementing IEC strategies tailored to local culture. Limitations include a single geographic focus and a cross-sectional design. Future research is suggested to use longitudinal designs and multi-regional comparative studies to explore the dynamics of discretion in different socio-cultural contexts.

Digital transformation has become a central agenda in local governments seeking to improve the effectiveness, accessibility, and reliability of public service delivery, particularly in population administration services that constitute the legal foundation of citizenship. In Indonesia, the Surabaya City Government has implemented the Klampid New Generation (KNG) program as an integrated digital platform for population administration services, aiming to streamline civil registration processes, enhance service quality, and expand citizen access. Despite its technological ambition, the implementation of digital population administration services continues to face persistent challenges related to administrative capacity, especially at the municipal level where services are operationalized and directly experienced by citizens. This issue raises an urgent academic and practical question regarding how administrative capacity shapes the performance and sustainability of digital public services within the broader digital government transformation. This article aims to synthesize and critically evaluate the existing scholarly literature on administrative capacity in the implementation of digital population administration services, with analytical relevance to the KNG program in Surabaya City Government. Employing an integrative literature review design, the study systematically examines peer-reviewed journal articles published between 2021 and 2025, retrieved from Scopus, DOAJ, Google Scholar, and SINTA databases. Articles were selected based on predefined inclusion and exclusion criteria and analyzed using thematic and conceptual synthesis techniques. The review identifies key dimensions of administrative capacity that consistently influence digital service implementation, including institutional and organizational arrangements, human resource competence, technological and infrastructural readiness, regulatory and procedural alignment, inter-organizational coordination, and the role of street-level bureaucrats in frontline service delivery.

Administrative capacity has long been recognized as a fundamental determinant of governmental effectiveness, yet its role in executive service delivery, particularly in relation to government protocol functions, remains conceptually underdeveloped in public administration scholarship. Existing studies on administrative capacity predominantly focus on policy formulation, implementation, and citizen-facing service delivery, while research on executive governance and executive support systems often treats internal support functions in aggregate terms. As a result, the specific contribution of protocol functions—as administrative, symbolic, and coordinative mechanisms that sustain executive leadership—has been largely overlooked. Addressing this gap, this literature review examines how administrative capacity operates within executive service delivery, with a particular emphasis on government protocol functions as an integral component of executive support and governance coordination. The primary objective of this article is to synthesize and integrate dispersed theoretical and empirical insights to reconceptualize protocol functions within the broader framework of Administrative Capacity Theory. Employing a narrative–integrative literature review approach, the study systematically selected and analyzed peer-reviewed journal articles from major academic databases published within the last five years. The literature was examined through thematic analysis and conceptual synthesis, guided by Administrative Capacity Theory as the core framework and complemented by perspectives on executive service delivery, institutional capacity, street-level bureaucracy, public service professionalism, and governance coordination. The review identifies recurring patterns indicating that effective executive service delivery depends on the interaction of individual-level capacities (professional competence, discretion, and ethics), organizational-level capacities (structures, procedures, and coordination routines), and system-level capacities (institutional arrangements and governance mechanisms).

Consular services have become a critical site of state intervention in the governance of international labor migration, particularly for migrant-sending countries such as Indonesia whose citizens depend on overseas missions for administrative protection and access to public services abroad. Despite the growing importance of consular institutions in safeguarding migrant workers’ rights and welfare, existing scholarship remains fragmented, offering limited conceptual integration of how administrative capacity shapes institutional readiness in cross-border public service delivery. Addressing this gap, this article presents a structured narrative–integrative literature review that synthesizes international peer-reviewed studies on administrative capacity, policy capacity, consular services, and migrant worker protection published in the last five years. Drawing on Administrative Capacity Theory as the core framework, complemented by Public Service Theory, Policy Implementation Theory, Street-Level Bureaucracy, and Institutional Theory, the review systematically analyzes how different dimensions of capacity configure institutional readiness in consular services. The findings reveal that institutional readiness emerges from the interaction of four interrelated dimensions: human resource capacity, organizational and procedural capacity, institutional and coordination capacity, and resource and infrastructure capacity. Rather than functioning as isolated determinants, these dimensions collectively shape how consular institutions translate formal mandates into service outcomes under conditions of transnational governance, legal pluralism, and fluctuating demand. The review further demonstrates that frontline discretion, coordination gaps, procedural rigidity, and uneven resource allocation are recurrent patterns across the literature, underscoring the dynamic and practice-based nature of administrative capacity in consular contexts. Theoretically, this article contributes to public administration scholarship by extending administrative capacity frameworks into the underexplored domain of cross-border public services and by integrating previously segmented theoretical perspectives into a coherent conceptual synthesis. By reframing consular services as institutionally embedded public service systems rather than solely diplomatic functions, the article advances understanding of institutional readiness in migrant worker protection and provides a robust analytical foundation for future empirical and comparative research in international public administration.
