Abstract

(General Background) Public service quality is a fundamental aspect of building public trust in government institutions, particularly in administrative services such as the issuance of driving licenses (SIM) managed by SATPAS. (Specific Background) However, despite the government’s efforts, the public often perceives the service as inefficient, with long queues, inconsistent procedures, and unprofessional staff attitudes. (Knowledge Gap) Previous studies have not specifically identified which service attributes most influence customer satisfaction and how these can be systematically improved. (Aims) This study aims to evaluate the quality of SATPAS services using the Importance Performance Analysis (IPA) method and to formulate improvement strategies through the 5W+1H approach. (Results) The findings show an average satisfaction score of 3.29 and a conformity level of 83%, indicating a service quality gap. Six attributes were identified as main improvement priorities: service punctuality, speed, staff readiness, information clarity, cost transparency, and staff politeness. (Novelty) The integration of IPA and 5W+1H provides a structured and practical framework for prioritizing and implementing service improvements. (Implications) The proposed model can be applied in other public institutions to enhance accountability, efficiency, and citizen satisfaction in public service delivery. Highlights: Identifies six key priorities for improving SATPAS service quality. Combines IPA and 5W+1H methods for targeted service enhancement. Provides a practical framework to boost efficiency and public trust. Keywords: Service Quality, Importance Performance Analysis, 5W+1H, Public Service, Customer Satisfaction

Abstract

General Background: Land administration in Indonesia involves diverse documentary evidence, particularly for uncertified land where formal titles are absent. Specific Background: Among commonly used administrative documents are IPEDA (Regional Development Contribution) records and Letter C village registers, both historically employed to document land control and fiscal obligations. Knowledge Gap: Despite frequent use in disputes, the comparative legal standing and evidentiary role of these two documents within the national land law framework remain insufficiently clarified. Aims: This study analyzes the juridical proof value of IPEDA and Letter C as evidence of land ownership in Indonesian land disputes. Results: Using a normative legal method with statutory, historical, and case approaches, the study finds that neither document constitutes formal proof of ownership under the national land registration system; however, both possess significant administrative and historical evidentiary value. Letter C records local land control and ownership history at the village level, while IPEDA demonstrates a fiscal legal relationship between individuals and the state regarding land utilization. When supported by continuous, legitimate, and undisputed possession, these documents may serve as initial evidence in first land registration or dispute resolution. Novelty: The research provides a comparative juridical evaluation of two non-certificate documents simultaneously, highlighting their complementary roles in evidentiary practice. Implications: The findings underscore the continued legal relevance of traditional administrative records as a bridge between customary land tenure and the formal modern land system, particularly amid ongoing digital transformation of land administration. Highlights: Village land registers document hereditary control history at the local level. Fiscal payment records indicate a state–individual legal relationship over land use. Both documents function as preliminary proof in registration or dispute processes when supported by continuous possession. Keywords:IPEDA; Letter C; Land Ownership Proof; Administrative Evidence; Land Dispute

Abstract

General background: Peatland ecosystems such as Paya Nie hold strategic ecological and socio-economic value as carbon sinks, biodiversity habitats, and community livelihood sources. Specific background: Despite these roles, Paya Nie faces degradation due to land conversion and weak enforcement of conservation norms. Customary law historically guided sustainable use, but its oral nature and reliance on social sanctions reduce its effectiveness in the face of modernization. Knowledge gap: Previous studies have emphasized either the ecological or legal dimensions but have rarely examined the synergy of customary law, social capital, and national law in peatland governance. Aims: This study employs a normative juridical method enriched with a socio-legal perspective to analyze the position of customary law in Indonesia’s legal system and its integration with social capital for ecological sustainability. Results: Findings confirm that while customary law is constitutionally recognized, its enforcement is limited, requiring revitalization through codification, strengthened social capital, and harmonization with national regulations. Novelty: The study introduces a governance model that integrates customary law, social capital, and state law as a synergistic framework for sustainable peatland management. Implications: This model contributes theoretically to socio-legal discourse and practically to policymaking, offering adaptive, participatory, and sustainable solutions for environmental conservation and community empowerment. Highlights: Integration of customary law, social capital, and national law strengthens peatland management. Codification and formal recognition enhance the enforcement of customary norms. Synergy model offers adaptive and participatory governance for sustainability. Keywords: Customary Law, Social Capital, Peatland Conservation, Environmental Governance, Sustainability

Abstract

General Background: Early childhood represents a critical period for rapid development, particularly in language acquisition, which underpins communication, social interaction, and cognitive growth. Specific Background: Play-based learning approaches, especially structured role-play activities within learning centers, provide opportunities for children to practice verbal expression in meaningful contexts. Knowledge Gap: Despite widespread adoption of role-play centers in early childhood classrooms, limited qualitative evidence documents how their implementation supports language development and what contextual factors facilitate or hinder success. Aims: This study analyzes the implementation of a role-play center learning model in developing young children’s language abilities and identifies supporting and inhibiting factors in its application at TK Aisyiyah 38 Driyorejo. Results: Using a qualitative narrative approach with interviews, observations, and documentation, the findings indicate noticeable progress in vocabulary acquisition, speaking confidence, sentence formation, and social communication. Contributing conditions include a well-prepared learning environment, active teacher facilitation, parental involvement, and institutional support, while constraints involve limited materials, diverse child characteristics, and insufficient parental understanding. Novelty: The study offers an in-depth contextual description of daily role-play center practices and their relationship to expressive and receptive language use in authentic classroom interactions. Implications: These findings suggest that structured role-play environments, supported by collaborative school–family engagement and adequate resources, can serve as a practical pedagogical framework for fostering early language development in preschool settings. Highlights: Children demonstrated expanded vocabulary, clearer utterances, and greater willingness to communicate during thematic simulations. Successful implementation depended on environmental readiness, educator guidance, and family participation. Resource limitations and varied learner traits posed practical challenges to classroom application.

Abstract

General Background Sentencing disparity is a persistent concern in criminal justice because unequal punishments for comparable offenses raise questions about fairness, proportionality, and legal certainty, including within military jurisdictions. Specific Background In the Indonesian military context, cases of indecency committed by members of the armed forces against the Extended TNI Family (KBT) fall under military court authority, where sanctions may include imprisonment and dismissal from service. Knowledge Gap Despite existing regulations and internal directives governing moral violations, limited research has systematically examined patterns of inconsistent sentencing and the judicial considerations underlying such differences in Military Court III Surabaya. Aims This study analyzes patterns of sentencing disparity and identifies factors shaping judicial reasoning in indecency cases involving TNI personnel against KBT within this jurisdiction. Results Normative legal analysis of four decisions shows variations in principal and additional punishments, including increases, reductions, consistency across appellate levels, and cases without dismissal due to prior discharge, reflecting differing emphases on retributive, corrective, and rehabilitative justice. Novelty The study provides a focused comparative examination of multiple case trajectories within a single military court region while assessing the application of internal TNI regulations and judicial discretion. Implications The findings indicate a need for clearer sentencing guidelines to ensure consistency, strengthen legal certainty, and maintain confidence in military justice processes. Highlights: Comparable misconduct received unequal prison terms and administrative sanctions across cases. Appellate review sometimes altered punishments while other cases remained unchanged through all levels. Judicial reasoning reflected different orientations toward punishment philosophies and case-specific conditions.
