This study aims to analyse the difficulties experienced by students in learning about flat-sided three-dimensional shapes. The research method employed is descriptive with a qualitative approach. The data collected in this study were obtained from students’ difficulty tests and interview results. The research subjects were Year 8 pupils at SMP Negeri 2 Ponelo Kepulauan in the 2024/2025 academic year. The interviews were conducted by selecting three questions related to difficulties in learning mathematics, with one student chosen as a respondent to be interviewed on 26 August 2025. The indicators used to assess students’ learning difficulties were: facts, principles, concepts, and operations. The research results indicate that students with the lowest marks demonstrated limitations in mastering all the indicators measured when solving mathematics problems on the topic of flat-sided three-dimensional shapes. During the interview, students with the lowest marks experienced difficulties despite the use of effective teaching methods. This was because they paid insufficient attention to what the teacher was explaining.

This study aims to analyze the implementation of mudarabah and murabahah contracts at the Baitut Tamwil Muhammadiyah (BTM) Al-Kautsar Islamic Cooperative in Makassar and to assess their compliance with Islamic principles and the Islamic Financial Accounting Standards (PSAK Syariah). The research employed a qualitative descriptive approach using in-depth interviews, observation, and documentation. The findings reveal that BTM Al-Kautsar has implemented mudarabah and murabahah contracts in accordance with Islamic principles, as evidenced by valid contract agreements, agreed profit-sharing ratios, and manual transaction recording. The mudarabah contract is applied for profit-sharing financing, while murabahah is more dominant due to its lower risk and stable returns. However, the application of PSAK Syariah remains suboptimal due to limited human resources, the absence of a Sharia supervisory board, and minimal digital accounting systems. These findings suggest the need to enhance Sharia literacy, strengthen internal supervision, and modernize accounting systems to support accountable and sustainable Islamic cooperative governance

The development of the digital era has significantly transformed government administration, particularly in technology-based public services. This transformation requires strengthening the principles of good governance, which include transparency, accountability, public participation, effectiveness, efficiency, and legal certainty. State Administrative Law plays a strategic role in ensuring that bureaucratic digitalization remains within the correct legal framework and does not deviate from good governance principles. This study employs a normative juridical approach with a literature review method to analyze the role of State Administrative Law in strengthening good governance in the digital era. The findings show that State Administrative Law functions as an instrument of legality, discretionary control, data protection, improved accountability, and enhanced public service efficiency. Thus, State Administrative Law is not only regulatory but also adaptive to technological developments in achieving good governance in the digital era.

Digital technology has, in many ways, altered the manner in which businesses function. This transformation touches on aspects like how products are developed, delivered, and sold. It opens up a range of possibilities for business owners to broaden their markets, boost profits, and make better use of online tools. At the same time, however, the digital age introduces certain difficulties. These include increased competition as well as risks related to practices that may conflict with sharia law—for example, charging interest, engaging in transactions with unclear risks, or producing counterfeit goods. The focus of this study is to examine the opportunities and challenges that businesses encounter in today’s digital world, viewed through an Islamic lens. The approach taken involves a review of existing literature, drawing from various sources dealing with digital commerce and Islamic economic principles. The results suggest that digital business ventures hold considerable promise, provided they are conducted with honesty, fairness, and transparency, while avoiding activities disallowed by sharia. This way, entrepreneurs can not only generate income but also develop their enterprises in a way that aligns with ethical and religious values.

The internship program of Universitas Mayjen Sungkono in Begaganlimo Village introduced a training initiative focused on the Development of an Adaptive Learning Platform Based on D-PACK as an effort to enhance the quality of digital learning in Begaganlimo elementary schools. This training was designed to assist teachers in strengthening their ability to design and utilize interactive learning media supported by artificial intelligence (AI). Through this socialization activity, teachers were not only introduced to the use of adaptive technology but also guided to apply it in teaching practices so that the learning process becomes more effective, easier to understand, and more engaging for students. In addition, the socialization activities provided a deeper understanding of how technology can be used and integrated into teaching. Teachers not only learned to operate AI-based applications or devices, but they also gained insight into the pedagogical principles within the DPACK framework, which ensures that technology is applied appropriately. As a result, learning is expected to become easier to understand, more engaging, and capable of increasing students’ participation and motivation in the classroom.

Household waste management in Gondang Village remains a major problem because waste is not sorted from the source and supporting facilities are still limited, resulting in mixed organic, inorganic, and residual waste, potentially polluting the environment. To support the planned development of a 3R Waste Management Site (TPS 3R) in 2026, a community service activity was conducted aimed at increasing community knowledge, awareness, and readiness regarding waste sorting and the application of the Reduce, Reuse, and Recycle concept. This activity used a participatory approach through outreach, waste sorting demonstrations, installation of educational boards on waste decomposition times, and the provision of separate trash bins in four hamlets. The results of the activity showed an increase in community understanding of waste types, 3R principles, and long-term environmental impacts, accompanied by positive responses and high enthusiasm. The educational boards and facilities provided served as visual reminders that encouraged behavioral change, making this activity an important first step in preparing the Gondang Village community towards sustainable waste management through the 3R Waste Management Site (TPS 3R).

Global business environmental uncertainty, triggered by "Black Swan" phenomena, demands that organizations transform beyond passive resilience toward anti-fragility capabilities, where Human Resource (HR) systems actually grow stronger through market disruptions. This study aims to analyze the concept of anti-fragility within organizational leadership, explain the role of transformational leadership in shaping anti-fragile employees, and identify organizational strategies for navigating market uncertainty. The approach employed is a narrative literature review using content analysis techniques across various reputable scientific journals, anti-fragility theory, and organizational case studies such as Disney+, Zoom, and Tractor Supply. Research findings indicate that transformational leadership acts as a primary catalyst that builds anti-fragility through intellectual stimulation, decentralized autonomy, and the creation of a culture that learns from failure. Organizational strategies prioritizing resource flexibility, cross-skilling, and optionality have proven effective in converting crisis stressors into opportunities for innovation and performance growth. The contribution of this article lies in the development of an "Anti-Fragile Leadership" conceptual framework that integrates the philosophical principles of anti-fragility into strategic HRM practices. The practical implications provide a guide for organizational leaders to design work systems that are adaptive and proactive toward market volatility, ensuring that organizations not only survive but thrive from chaos.

This research is prompted by legal complications within civil procedural law, specifically regarding the failure of judges to identify formal defects in special powers of attorney during the preliminary stages of trial. The central focus of this study examines Decision Number 14/Pdt.G/2025/PN Kba, in which a lawsuit was declared inadmissible (Niet Ontvankelijke Verklaard) only after a seven-month litigation process that had already progressed through evidentiary hearings and local inspections. The objective is to evaluate the effectiveness of the dominus litis principle in empowering judges to provide procedural guidance for lawsuit amendments, while testing its alignment with the principles of simple, fast, and low-cost justice. Employing a normative legal research method with statutory and case-based approaches, the legal materials are analyzed qualitatively using the legal syllogism technique. The findings indicate that the application of the dominus litis principle in the a quo case remains ineffective due to the judges' passive and formalistic tendencies. Such an approach neglects the ex-officio authority mandated under Articles 119 and 132 of the HIR. This ineffectiveness results in significant judicial inefficiency, causing undue loss of time and financial resources for justice seekers. Consequently, this study recommends strengthening rigorous initial screening mechanisms by the panel of judges at the first hearing. This preventive measure is essential to curb the waste of judicial resources and ensure the realization of substantial justice for all disputing parties.

The absence of specific regulations governing the mechanism and legal consequences of revoking special power of attorney during ongoing civil court proceedings creates a legal vacuum that generates uncertainty for all parties involved. This study aims to analyze the legal consequences of unilateral revocation of special power of attorney on the continuity of civil proceedings and the legal standing of attorneys thereafter. Using a normative juridical approach through statutory and conceptual methods, data were collected through library research and analyzed qualitatively using a prescriptive method. The results show that unilateral revocation during ongoing proceedings creates a formal defect that risks rendering the lawsuit inadmissible before the merits are examined, obstructing the principles of simple, fast, and low-cost justice as mandated by Law Number 48 of 2009. Furthermore, the attorney loses formal legitimacy to represent the principal from the moment revocation is notified, though all prior legal actions remain binding upon the principal as the material party, and such revocation without valid legal basis constitutes a breach of contract obligating the principal to pay compensation under Article 1809 of the Civil Code. This study concludes that regulatory reform is urgently needed to fill the existing legal vacuum and ensure legal certainty in civil court proceedings in Indonesia.

This study explores how young legislative candidates at the local level utilize Instagram as a campaign medium in the era of political digitalism. The focus is on two DPRD candidates in Tangerang City during the 2024 election in Electoral District 3 (Cipondoh–Pinang): Muhamad Azka Nur Fauzi from the National Mandate Party and Ashma Nafilah Maulida from the Prosperous Justice Party. Employing a qualitative descriptive approach and in-depth interviews with key informants, this research analyzes their personal branding strategies using Peter Montoya’s eight laws of personal branding.  The findings reveal that despite their relatively small number of followers, both candidates successfully built authentic and community-relevant political images. MANF emphasized UMKM development and religiosity, aligning with his personal background, while ANM highlighted humanistic social programs and her unique writing hobby. Nevertheless, both still showed weaknesses in several of Montoya’s principles, particularly distinctiveness and visibility consistency. The study concludes that Instagram is not merely a low-cost promotional tool but a strategic platform for local candidates to foster public trust, provided their personal branding remains authentic, consistent, and responsive to local needs.

This community service program addresses the growing ethical challenges of design practices in social media, particularly among children and adolescents. Social media platforms are not merely communication tools but persuasive digital products that influence behavior, emotions, and information consumption. This program aimed to enhance ethical design literacy among members of the Children’s forum in Tangerang Regency through an interactive workshop combining theoretical education, case studies, and practical design exercises. The methodology involved participatory training sessions, including lectures on design ethics, identification of dark patterns, privacy-by-design practices, and hands-on content creation using social media platforms. The results indicate increased participant awareness of ethical principles such as transparency, visual honesty, respect for copyright, and privacy protection. Participants demonstrated improved ability to identify unethical design elements and to produce simple yet responsible visual content. The program contributes to strengthening digital ethics awareness among young social media users and highlights the importance of collaborative, community-based approaches in fostering responsible digital culture.

The relocation of the Social Welfare Shelter Environment (Lingkungan Pondok Sosial/Liponsos) in Sidoarjo represents a strategic effort to address social and spatial issues characterized by overcapacity, limited facilities, and an inadequate living environment that does not fully support the physical and psychological needs of people with social welfare problems (PMKS). These conditions indicate that the challenges faced by Liponsos are not merely social in nature but are also closely related to the quality of the built environment, which significantly influences the rehabilitation and recovery process of its residents. Therefore, a human-centered design approach is required in planning social service facilities. This study aims to analyze the application of humanistic architecture principles in the planned relocation of the Sidoarjo Liponsos as a foundation for creating a more livable, dignified, and user-oriented environment. The research employs a literature review method by collecting data from relevant books, journals, regulations, and previous studies. The analysis is conducted using descriptive and content analysis to examine the relationship between humanistic architectural principles and the needs of residents within social welfare facilities. The results indicate that the humanistic architectural approach is highly relevant to the relocation of Liponsos, particularly through spatial zoning based on levels of privacy and security, the provision of green open spaces and communal areas as media for social interaction and therapeutic activities, and the design of self-development spaces that support rehabilitation and empowerment. The implementation of these principles is expected to create a built environment that not only fulfills basic functional requirements but also supports psychological recovery, social stability, and sustainable improvement in the quality of life of PMKS residents.  

UMKM Digital transformation in local governance is an important instrument in realizing the principles of good governance, especially in regions with complex geographical challenges. This study aims to analyze the effectiveness of e-government implementation at the district level in encouraging community participation in the local development planning process, using a case study of the Fof District Office, Tambrauw Regency. The methods used were descriptive qualitative through field observations, in-depth interviews with district officials and community leaders, and analysis of development documents. The data was analyzed through the stages of reduction, presentation, and drawing conclusions. The results of the study show that the implementation of e-government in Fef District is in a transition phase. Bureaucratic digitization improves administrative efficiency and transparency of public information. However, its effectiveness in expanding community participation is still low. The main obstacles include limited telecommunications infrastructure in several villages and low community digital literacy. As a result, participation in Musrenbang remains dominated by conventional mechanisms, while digital platforms serve primarily as a means of one-way reporting. This study emphasizes that the success of digital transformation depends on the readiness of infrastructure and community capacity, so a hybrid approach that integrates technology with local wisdom is needed to strengthen participation in regional development.

The role of ports as crucial nodes in the global supply chain positions the maritime sector as one of the most dynamic industries worldwide. This research analyzes the strengthening of business law support maritime sector integration to enhance port operational efficiency and the role of business law instruments in realizing the principle of fair competition within ports. This research employs a normative legal approach focusing on the study of existing legal norms and regulations governing port management and maritime integration. The strengthening of business law in the maritime sector plays a crucial role in improving port operational efficiency. A strong and well coordinated business law framework will create ports that are more efficient, competitive, and adaptive to the changing demands of the global market. Several key principles must be developed. First, rules on information disclosure and accountability to ensure transparency in port governance. Second, prohibitions against abuse of dominant positions and oversight of vertical integration to prevent anti-competitive practices. Third, clear contractual norms and governance structures for public private partnerships (PPP), including proportional risk-sharing mechanisms to ensure fairness and efficiency in infrastructure development. Fourth, multi-level governance alignment across national and regional authorities to prevent incentive distortions.

The Regional Public Library of Sidoarjo Regency plays an important role as a public facility in supporting the development of community literacy. Along with population growth and the advancement of the education sector, the library is required to provide spaces that are comfortable, safe, and inclusive for all users. However, existing conditions indicate various architectural problems that potentially hinder the optimal function of the library. This study aims to identify architectural issues at the Regional Public Library of Sidoarjo Regency, including building conditions, spatial layout, user comfort, and the availability of thematic literacy facilities and inclusive spaces. The research method employed observation and literature review. Field observation was conducted to document the actual conditions of the building and library facilities, while the literature review focused on library standards, building regulations, and relevant architectural theories. The results show that although the library building is structurally adequate, the quality of space has not fully met the required standards of comfort, safety, and functionality. The spatial arrangement remains conventional and lacks flexibility, limiting its ability to support diverse literacy activities. In addition, thematic literacy facilities and the application of inclusive design principles are still limited. This study concludes that architectural development efforts are needed, focusing on improving spatial quality, implementing adaptive spatial planning, and providing more diverse and inclusive literacy facilities. The findings are expected to serve as a reference for future development planning of the Regional Public Library of Sidoarjo Regency in order to enhance its role as an educational public space and a community literacy center.

Drug misuse continues to be a complicated social and legal issue that has an impact on societal stability, public health, and personal wellbeing. Many criminal justice systems have moved away from punitive tactics in favor of rehabilitation-focused ones in recent years, especially for drug users who are frequently viewed as sufferers of addiction rather than serious criminals. The National Narcotics Agency (BNN) in Indonesia is implementing rehabilitation programs and restorative justice processes as a result of this change. This study investigates the efficacy of restorative justice in drug rehabilitation at Jambi Province's National Narcotics Agency and evaluates its applicability from the standpoint of Islamic law, specifically the framework of maqāṣid al-sharīʿah. The study uses a case study design and a qualitative methodology. Participant observation, document analysis, and in-depth interviews with BNN officials, rehabilitation counselors, medical staff, and ex-drug users were used to gather data. The results show that an integrated evaluation system that assesses drug users' physical, psychological, and social states in order to determine their eligibility for recovery is used to institutionally apply restorative justice principles. Combining medical care, psychological counseling, and social reintegration programs, the rehabilitation programs greatly aid in participants' recuperation, enhance psychological stability, and fortify familial ties. Additionally, by promoting individual responsibility, family support, and community involvement, restorative justice-based rehabilitation lowers the risk of recidivism. From the standpoint of Islamic legal philosophy, these actions are consistent with the goals of maqāṣid al-sharīʿah, specifically the defense of human dignity, life (ḥifḍ al-nafs), and intellect (ḥifḍ al-ʿaql). According to the study's findings, restorative justice-based rehabilitation is a compassionate and successful method of treating drug dependency while encouraging social reintegration and long-term recovery.

Good governance has become a crucial framework for improving public sector effectiveness, accountability, and responsiveness to citizens’ needs. In Indonesia, decentralization policies since 1999 have devolved significant authority and resources to local governments, creating both opportunities and challenges in implementing good governance principles. This study examines administrative reform efforts in Indonesian local governments, focusing on progress, challenges, and key success factors. Using a multiple case study design, the research analyzed reform initiatives in six district/city governments with diverse contexts. Data were collected through document analysis, semi-structured interviews with government officials, civil society representatives, and citizens, as well as direct observation of administrative processes conducted between March and November 2024. The study assessed six core principles of good governance: participation, transparency, accountability, effectiveness and efficiency, equity and inclusiveness, and rule of law. The findings reveal variations in implementation across regions, with high-performing governments demonstrating strong leadership commitment, systematic planning, active citizen engagement, and effective monitoring mechanisms. However, challenges persist, including limited capacity, bureaucratic resistance, weak accountability enforcement, and low public participation. Key success factors include visionary leadership, capacity development, strategic partnerships, and institutional strengthening. Policy recommendations emphasize enhancing local capacity, accountability systems, citizen participation, and performance evaluation.

The development of digital media has transformed Islamic da’wah into a digitally mediated form of religious communication, reshaping structures of authority, engagement, and community formation. However, existing research remains fragmented and lacks a comprehensive structural map. This study conducted a Systematic Literature Network Analysis (SLNA) of Scopus-indexed publications on Islamic da’wah via digital platforms from 2016 to 2026. Using PRISMA-based screening techniques and bibliometric methods—including co-authorship, co-citation, and co-occurrence analyses with VOSviewer—the study analyzed 74 peer-reviewed journal articles. The results indicate a significant increase in the number of publications, particularly following the COVID-19 pandemic. The field is structured around four main themes: platform-based engagement strategies, youth identity formation, digital authority and ethics, and the adaptation of prophetic communication principles to the online context. Although Indonesia and Malaysia dominate the research output, the collaborative network remains relatively dispersed. New topics such as the influence of algorithms and AI-supported da‘wah suggest an expansion toward interdisciplinary directions. This study provides the first comprehensive map based on Scopus for research on Islamic digital da‘wah and offers a foundation for future theoretical and empirical development.
