The Pious Children Festival is a collaborative work program implemented by students (KKN) of Batang Hari Islamic University in Jelutih Village, Batin XXIV District. This activity aims to instill religious values ​​and strengthen children's self-confidence from an early age. A pious child is defined as an individual who consistently behaves well, possesses strong faith, and is devout in practicing Islamic teachings. The objectives of the Pious Children Festival include: (1) increasing children's enthusiasm for studying Islamic teachings, (2) developing children's interests and talents in religious matters, and (3) fostering children's self-confidence in showcasing their abilities. This activity is packaged in the form of religious competitions that include the call to prayer (adhan), memorization of short surahs (chapters), daily prayers, Qur'an recitation, and an Islamic fashion show. Participants from the PAUD (Early Childhood Education), Kindergarten (TK), and RA (Islamic Elementary School) levels take part. The implementation method involves several stages: analyzing the needs of early childhood children, planning activities, implementing programs, and evaluating and following up on the results. The results of the Pious Children Festival demonstrated an increased enthusiasm among the children of Jelutih Village for learning about Islam. Furthermore, this activity also had a positive impact on increasing the children's courage and confidence in showcasing their religious talents. This was evident in the changes in the attitudes of several boys who previously lacked confidence in performing the call to prayer, but after participating in this activity, became more courageous and confident.

Conflicts in transmigration areas are generally multidimensional and influenced by social, economic, land, and institutional factors. This study aims to identify the forms and distribution of conflicts in three districts of the transmigration area, namely Momi Waren District, Ransiki District, and Oransbari District, as well as to formulate a smart system-based conflict resolution approach through the use of spatial data, local institutions, and local wisdom-based settlement practices. Based on field mapping, four main categories of conflict were identified: 1) Land conflicts occur throughout the transmigration sites in the form of claims to transmigration land that has not been handed over to transmigrants because the compensation price is below normal. In addition, there is no ATR BPN office in South Manokwari Regency, one of whose functions is community empowerment and conflict resolution. 2) Economic conflicts occur because transmigrants are registered and recorded in the population registry, making it easy for them to access capital. Several economic activities in agriculture and transportation services are dominated by transmigrants, causing economic jealousy. 3) Social conflicts occur when the distribution of social assistance is uneven and the excessive use of illegally sold alcoholic beverages causes social unrest. 4) Institutional conflicts occur when civil servants, police, and military personnel are recruited, and not all indigenous Papuans who are nominated can be accommodated, requiring the involvement of tribal councils to formulate recommendations for recruitment that prioritize indigenous Papuans. The root causes of the conflict were analyzed using a root cause analysis approach that covered unclear land boundaries, unequal economic access, weak coordination between institutions, and low social trust due to differences in interests between groups. This study utilizes best practices from the Tribal Council, the South Manokwari Regency Transmigration and Manpower Office, the Religious Harmony Forum, and the Social Services Office as the basis for developing smart maps for an early warning system for conflicts. The results of the study formulate a Smart Conflict Resolution System framework consisting of three main components: (1) participatory spatial mapping of conflicts and key actors, (2) integration of institutional databases and social-customary mediation channels, and (3) design of smart maps as a mitigation and decision-making tool in transmigration areas. This system is expected to strengthen collaborative governance, prevent conflict escalation, and realize inclusive and sustainable management of transmigration areas

This article explores the concept and implementation of restorative justice in Indonesia, an approach currently at a crucial crossroads within the criminal justice system. Rather than solely focusing on punishment, restorative justice offers a path towards repairing relationships between victims, offenders, and the community, seeking solutions oriented around conflict resolution. Through comprehensive analysis, this paper identifies the philosophical foundations and regulations supporting the adoption of restorative justice, while dissecting the dynamics of its application across various levels of legal processes in Indonesia. However, this noble endeavor is not without its challenges, ranging from institutional resistance and uneven understanding to harmonization with the conventional criminal law framework. Behind every case lies a human story yearning for more substantive justice. Therefore, this article argues that the success of restorative justice does not merely lie in its legal umbrella, but in our ability to understand and embrace the human dimension in every dispute resolution process. Consequently, this paper recommends adaptive and collaborative strategies to strengthen the role of restorative justice, ensuring it can guide our criminal justice system towards a more just and dignified future for all parties.

This study aims to determine how the implementation of the cooperative learning model can contribute to students' cognitive development in Islamic Religious Education (PAI) at SMA Negeri 1 Kasihan. The background of this study is based on the low level of active student involvement in the PAI learning process, which is still dominated by conventional lecture methods. The study used a qualitative approach with data collection techniques through observation, interviews, and documentation of PAI teachers and grade 11 students. The results showed that the implementation of cooperative learning encouraged students to be more active in discussions, think critically, and understand religious concepts in depth. This model also improved social skills, responsibility, and collaboration among students. Thus, cooperative learning not only strengthens the cognitive domain but also develops students' affective and psychomotor aspects in a balanced manner. These findings demonstrate that cooperative learning is effectively used in PAI learning as an effort to create an interactive, collaborative, and meaningful learning process.

Islamic Educational Philosophy holds a pivotal role in directing the learning process to remain consistent with Islamic principles. This article seeks to explore how the values of Islamic Educational Philosophy are implemented in the learning activities at the Institute of KH Ahmad Sanusi, with a focus on fourth-semester students. The study adopts a qualitative approach using a descriptive-analytical design based on library research and the examination of instructional practices. The results reveal that Islamic Educational Philosophy serves as a conceptual framework for determining and applying learning strategies, including discussion and inquiry-based learning, which foster active participation, critical thinking, and the internalization of Islamic values. Learning assessment is carried out in a comprehensive manner by addressing cognitive, affective, and psychomotor domains through individual assignments, collaborative tasks, formal examinations, and academic writing activities. Moreover, the emphasis on self-reflection (muhasabah) enhances students’ awareness of their moral and spiritual responsibilities in the process of seeking knowledge. The application of Islamic Educational Philosophy is therefore expected to support the development of students who are intellectually competent, morally grounded, and reflectively aware as future educators and Muslim intellectuals.

This research analyzes the Indonesian government’s policy responses to combating Illegal, Unreported, and Unregulated (IUU) Fishing in the Arafura Sea during 2023-2024, focusing on the case of the Run Zeng 03 and Run Zeng 05 vessels. These foreign-flagged vessels, owned by a Chinese company but registered under the Russian flag, were involved in illegal fishing and human rights violations against Indonesian fishery crew members. Using a qualitative descriptive approach supported by literature studies and official government data, this research analyzes how Indonesia implemented its maritime sovereignty through legal enforcement, inter-agency coordination, and international maritime diplomacy. The findings reveal that Indonesia’s measures, such as vessel monitoring AIS/VMS technology, law enforcement through arrests and seizures, and diplomatic engagement with flag states reflect a progressive but still reactive approach. The study identifies key challenges, including limited foreign authorities. This research highlights the need for an integrated policy framework that combines hard power (law enforcement and patrols) with soft power (international cooperation, economic diplomacy, and labor protection). The study concludes that a comprehensive and collaborative approach is essential to strengthen maritime governance and ensure sustainable, equitable management of Indonesia’s marine resources.

The Great Mosque of Banten is a historical heritage that reflects cultural acculturation and the glory of Islam in the Indonesian archipelago. This study aims to analyze the forms of collaboration between the government, local communities, and site managers in preserving the Great Mosque of Banten using the Collaborative Governance theory by Ansell and Gash (2007). A descriptive qualitative approach was applied through interviews, field observations, and document studies conducted in the Great Mosque area. The findings reveal that collaboration among stakeholders has not yet reached optimal levels due to limited communication, trust gaps, and conflicting interests. Nevertheless, functional cooperation has emerged through joint activities in sanitation, security, and tour guide training. Based on the five indicators of the collaborative process, direct communication (face to face dialogue) and trust building remain major challenges, while shared understanding between government agencies, the foundation, and the community has begun to develop. This study highlights the importance of sustainable collaborative governance in preserving the religious, historical, and social values of the Great Mosque of Banten while supporting the welfare of the surrounding community.

This study explores the implementation of interpersonal communication between tutors and students in speaking class activities at the Kind English Course by applying DeVito’s Interpersonal Communication Theory. Interpersonal communication plays a vital role in English language learning, especially in speaking classes where real-time interaction directly shapes students’ engagement and learning outcomes. Using a qualitative literature review method, this research examines how the five key components of interpersonal communication—openness, empathy, supportiveness, positiveness, and equality—are applied within instructional practices. The analysis reveals that tutors who demonstrate openness and empathy foster stronger emotional connections with students, which encourages them to speak more confidently. Supportive and positive communication behaviors further create a safe and motivating learning environment where students feel valued and understood. Additionally, the principle of equality helps reduce hierarchical barriers, enabling more collaborative and interactive learning dynamics. Overall, the findings indicate that the consistent application of interpersonal communication principles significantly enhances students’ participation, confidence, and speaking proficiency. This study contributes to a deeper understanding of how communication quality influences language learning and underscores the importance of interpersonal competence among tutors in developing effective and engaging speaking class experiences.

This study examines the role of the private sector in collaborative politics to strengthen human security in preventing human trafficking in Kupang City, East Nusa Tenggara Province. Human trafficking is an extraordinary crime that poses serious threats to human security, particularly for Indonesian Migrant Worker Candidates (CPMI) who are highly vulnerable to exploitation and illegal recruitment. The complexity of this issue requires the involvement of multiple actors, including not only the government but also the private sector. This research employs a qualitative descriptive method, with data collected through interviews, observation, and documentation. The research sites include BP3MI East Nusa Tenggara as a government representative and two private companies, PT Bakti Unggul Sejahtera (PT BUS) and PT AKKA AL-MATAR. The analysis is based on the collaborative governance framework proposed by Ansell and Gash, which emphasizes face-to-face dialogue, trust building, commitment to the process, shared understanding, and intermediate outcomes. The findings indicate that collaboration between the government and the private sector plays a significant role in preventing human trafficking through legal recruitment processes, pre-departure training, capacity building, and supervision of labor placement procedures. Although challenges remain in coordination and policy consistency, these collaborative practices contribute positively to strengthening the protection of migrant workers’ rights and security. This study concludes that collaborative politics between the government and the private sector is a crucial strategy in developing a human security–oriented human trafficking prevention system

The English Fun Tales program is a community service activity aimed at improving children's English literacy through the use of picture books. This activity was carried out at Rumah Belajar Jadi Mulya, Salatiga, which serves as a non-formal learning center for children from the surrounding area. The background of this program stems from the limited access of children in the area to attractive, interactive, and developmentally appropriate English learning resources. The implementation method includes: (1) providing English picture books selected according to the children's language ability and age; (2) guided shared reading activities; (3) simple discussions about story content to train comprehension; and (4) creative activities such as drawing story characters, role-playing, or story retelling. This approach is designed to combine cognitive, affective, and psychomotor aspects, so that children not only understand vocabulary and language structure but also develop imagination, self-confidence, and reading interest. The implementation results show an increase in reading interest, expansion of English vocabulary, and children's courage in expressing themselves orally. In addition, social interaction among participants becomes more positive through collaborative activities. This program is expected to serve as a model for English literacy learning based on picture books that can be replicated in other learning communities with local context adjustments.

Civil servants (ASN) entering retirement represent a strategic human resource asset for national development; however, their potential is often underutilized due to an institutional vacuum. This study identifies this fundamental problem as manifesting in two dimensions: the absence of a cohesive structure among the retired community and the lack of a structure that systematically connects them to the economic empowerment ecosystem. Consequently, the transition from active service to a productive retirement period presents a significant challenge. The purpose of this research is to design an effective institutional forum model to serve as a facilitative bridge. The analysis employs a framework integrating three pillars: Mochtar Kusumaatmadja's Development Law Theory as the philosophical foundation, Ansell and Gash's Collaborative Governance concept as the governance paradigm, and the Pentahelix model as the operational framework. This study proposes a multi-stakeholder collaborative forum designed to synergize the roles of government, industry, academia, communities, and the media. The primary recommendation is the establishment of a formal entity functioning as an incubator and accelerator. This entity is intended not only to address the economic needs of retirees but also to align with the country's constitutional mandate to achieve sustainable social welfare.
