The establishment of national territorial boundaries is a strategic priority to safeguard sovereignty, maintain security stability, and strengthen bilateral relations between Indonesia and Malaysia as well as Timor-Leste. As of 2024, there remain nine Outstanding Boundary Problems (OBP) with Malaysia and two unresolved segments with Timor-Leste. These issues stem from the continued relevance of outdated colonial agreements, limited diplomatic capacity, weak inter-agency coordination, and minimal support from modern surveying technology. Based on an analysis of four policy alternatives using the criteria of effectiveness, efficiency, and long-term impact, the Strengthening of Intensive Bilateral Diplomacy has been identified as the priority policy. Implementation is directed to the Badan Nasional Pengelola Perbatasan (BNPP) as the main coordinator, supported by regulatory frameworks, diplomatic resources, and cross-ministerial/institutional coordination. Through this strategy, the resolution of pending boundary segments can be accelerated, legal certainty over national territory can be strengthened, security stability in border areas can be improved, and bilateral relations can become closer. Furthermore, Indonesia needs to strengthen diplomatic strategies, leverage technology, and enhance inter-agency coordination to accelerate the resolution of national border disputes. This policy directly contributes to achieving territorial sovereignty and sustainable development toward Indonesia Vision 2045.

Infrastructure development as a National Strategic Project (NSP), such as the Yogyakarta-Bawen Toll Road, aims to improve public welfare but often faces a crucial issue in the land acquisition process, namely the determination of compensation. This research examines the application of substantive justice, which focuses not only on procedural compliance (procedural justice) but also on the fairness and adequacy of the final outcome for the entitled parties. Using a juridical-empirical approach, this article analyzes two main problems: first, how substantive justice is realized in the deliberation stage of determining compensation and what factors cause disagreement from residents. Second, how the overall stages of land acquisition affect the achievement of substantive justice and the obstacles encountered. The analysis shows that although the land acquisition stages have procedurally followed Law No. 2 of 2012, the achievement of substantive justice is still hindered. Factors such as the appraisal of compensation which is deemed not to cover non-physical losses, lack of transparency, and an imbalanced bargaining position in deliberations are the main causes of disagreement. Obstacles in the planning, socialization, and payment stages also impede the realization of a complete sense of justice for the affected communities. This study is expected to contribute to the development of land acquisition policies that prioritize fairness, transparency, and the protection of the rights of affected communities.

Population administration services are essential public services that fulfill the civil rights of the community. However, the process of changing Family Card (KK) data at the village level often faces problems, such as complicated procedures and limited access to services. With the development of information technology, village governments are required to implement digital-based service innovations through a digital governance approach. This study aims to evaluate the effectiveness of digital governance implementation in population administration services through the LAPAK SARAH application for Family Card data changes in Dayu Village, Nglegok District, Blitar Regency. The approach used in this study is descriptive qualitative with data collection techniques in the form of in-depth interviews, observation, and documentation. Research informants included village officials and community members as service users. The results showed that the use of the LAPAK SARAH application could improve the performance of population administration services, as indicated by faster service times, easier access, and increased service transparency and accountability. From a digital governance perspective, the role of village officials, cooperation with the Population and Civil Registration Office, and community participation improved service quality. However, this study also found obstacles such as limited digital literacy among the community, differences in village device capacity, and technical infrastructure constraints. The success of digital population administration services at the village level is not only determined by the use of technology, but also by the quality of governance and the readiness of the parties involved.

Nahwu (Arabic grammar) is a fundamental discipline in learning the Arabic language, helping to prevent errors in speech and serving as a primary key to clearly understanding Islamic legal texts. However, in practice, the teaching of Nahwu often faces complex challenges, particularly the lack of active participation among female students and their uneven mastery of the subject. Therefore, this study aims to explore the problems in teaching Nahwu at Al-Madani Islamic Boarding School in Cikalong and to identify the factors causing these issues. This study aims to: (1) reveal the problems faced by second-grade female students of KMI in learning Nahwu at Al-Madani Islamic Boarding School in Cikalong, and (2) identify the contributing factors influencing the emergence of these problems. This research employs a descriptive qualitative approach. The researcher used three data collection techniques: classroom observation, in-depth interviews with the Nahwu teacher, and questionnaires distributed to the students. For data analysis, the researcher applied the Miles and Huberman model, which consists of data reduction, data display, and conclusion drawing. To ensure data validity, data triangulation techniques were used. The results of the study indicate that the problems are divided into two main aspects: (1) learning-related problems, including the gap between memorization of grammatical rules and their application (i‘rab), high levels of academic anxiety, and decreased classroom concentration; and (2) contributing factors, including methodological factors, linguistic-psychological factors, and classroom management factors. The researcher suggests that teachers adopt more interactive teaching methods and media, as well as innovative visual tools to reduce the abstract nature of Nahwu materials and enhance students’ functional understanding. Additionally, activating “Halaqah Nahwiyyah” (grammar study circles) in dormitories is recommended to overcome psychological barriers and improve students’ linguistic confidence.

Post section caesarea (SC) and method of operative female sterilization (MOW) are surgical procedures that may cause various problems, such as pain, limited mobility, decreased muscle strength, and risk of postoperative complications. Physiotherapy management through exercise therapy is an important intervention to accelerate the recovery process. Objective this study aimed to determine the effectiveness of exercise therapy in improving the functional condition of patients post SC and MOW in Annisa Ward 32 A at PKU Muhammadiyah Karanganyar Hospital. Method: used was a case report on a 33-year-old female patient following SC and MOW procedures. The physiotherapy interventions included deep breathing exercises, active range of motion exercises of the extremities, light abdominal muscle contractions, gradual early mobilization, as well as breast massage and oxytocin stimulation. The results showed a reduction in pain from a scale of 4–5 to 2–3 based on the Numeric Rating Scale (NRS), improvement in mobility such as independent position changes, and increased activity tolerance, including sitting and walking with minimal assistance. In addition, the patient showed increased confidence in performing daily functional activities. Conclusion: exercise therapy has a positive effect on improving mobility, reducing pain, and accelerating functional recovery in post SC and MOW patients. Therefore, exercise therapy is recommended as an essential component of postoperative physiotherapy management to improve patients' quality of life.

This study discusses the dialogue between Christian faith and Karl Marx’s atheism as well as its relevance to the lives of contemporary Christians. The rise of atheism in modern society is closely related to secularization, scientific progress, social inequality, and criticism of religious institutions that are considered unable to answer humanitarian problems. Karl Marx viewed religion as an ideological instrument that often legitimized oppression and alienated humans from their true existence. Through his famous statement that “religion is the opium of the people,” Marx criticized forms of religiosity that merely comfort human suffering without striving for social liberation. This research employs a qualitative method with a literature review approach by examining various philosophical, theological, and social sources related to Marx’s atheism and the Catholic Church’s teachings. The findings reveal that Marx’s criticism of religion should not merely be understood as a rejection of God, but also as a moral challenge for the Church to continuously renew itself in carrying out its mission amid social realities. In response, the Catholic Church, especially through the teachings of the Second Vatican Council, views atheism not only as a doctrinal challenge but also as an opportunity for dialogue and self-reflection. The study concludes that authentic Christian faith is not an escape from worldly realities but a spiritual force that encourages believers to uphold justice, solidarity, and human dignity. Therefore, Marx’s criticism can become a reflective instrument for Christians to embody a more contextual, humanistic, and socially engaged faith in the modern world.

This study aims to analyze the legal protection of women's inheritance rights from the perspective of Indonesian civil law. The problems studied focused on the position of women as heirs and the extent to which the legal system provides guarantees of justice and equality. The research method used is normative juridical with a legislative and conceptual approach. Data was obtained through a literature study of legal regulations, doctrines, and court decisions relevant to inheritance issues. The results of the study show that normatively, civil law provides equal recognition of women's inheritance rights, especially in the Civil Code. However, in practice, there are still obstacles influenced by patriarchal culture and customary law that tend to place women in subordinate positions. This condition causes women to often experience difficulties in claiming or obtaining the proper share of inheritance. Therefore, it is necessary to strengthen regulations, harmonize national laws with the value of gender equality, and increase public legal awareness to ensure effective and fair protection for women in obtaining their inheritance rights.

Adolescence is a transitional period marked by rapid biological, psychological, and social changes, which often lead to various problems for individuals, particularly at the high school level. This study aims to analyze the role of guidance and counseling services in addressing these issues using a literature review approach. The method employed is a systematic literature review of relevant scientific publications from 2020 to 2026. The data collection process was carried out through the search, selection, and evaluation of literature related to student issues and guidance and counseling services in schools. The research findings indicate that students face various challenges, such as difficulties in learning, low academic ability, academic stress and anxiety, as well as social-emotional issues influenced by internal and external factors. Guidance and counseling services play a role in supporting students to self-reflect, overcome problems, and optimize their potential through preventive, curative, and developmental approaches. The success of these services is also supported by the role of counselors, collaboration with other teachers, and parental participation. However, in practice, there are still a number of obstacles, such as limited human resources, a lack of coordination, and an incomplete understanding of the functions of these services. Therefore, efforts are needed to improve implementation and cooperation so that guidance and counseling services can operate more efficiently.

Differential equations involve derivatives of unknown functions and are widely used in mathematical modeling of various real-world problems. They can be classified based on linearity, homogeneity, coefficients, number of independent variables, degree, and order, thus requiring appropriate solution methods. One commonly used approach is the reduction of order method, which simplifies equations by reducing their order step by step. However, this method generally requires the solution of the corresponding homogeneous equation as an initial step. This study aims to solve nonhomogeneous linear ordinary differential equations of order with constant coefficients using the reduction of order method without determining the homogeneous solution. This research is a theoretical study based on relevant references concerning solution methods and types of differential equations. The procedure consists of two main stages: determining the fundamental symmetric polynomial variables based on the coefficients and constructing a sequence of solutions through first-order linear differential equations obtained from the reduction process. The results show that this method systematically produces the general solution of linear differential equations of order , making it an effective and efficient alternative approach

This study aims to analyze students’ mathematical reasoning abilities in quadratic function material through the use of Desmos. The research employed a qualitative descriptive approach using a case study and usability testing method. Data were collected through post-tests and interviews involving students’ responses in solving quadratic function problems. The analysis focused on several indicators of mathematical reasoning, including procedural skills, conceptual understanding, and analytical ability. The results show that students generally demonstrate adequate procedural reasoning, particularly in substitution and computation tasks. They are also able to relate algebraic representations to geometric interpretations, such as determining intercept points and analyzing the direction of parabolas. However, limitations were found in conceptual understanding, especially in identifying graph characteristics without relying on procedural steps. The use of Desmos significantly supports the development of students’ mathematical reasoning by providing real-time visualization, facilitating exploration of function parameters, and enabling verification of results. Overall, Desmos contributes to enhancing procedural, conceptual, and analytical dimensions of mathematical reasoning, although its effectiveness depends on proper instructional design.

This study aims to examine Deuteronomy 22:13-30 using a hermeneutic approach and relate it to the current level of awareness of early marriage among Christian congregations. The method used was a qualitative literature study, with the Bible as the primary source, supplemented by various related theological literature. The results indicate that this section of the text contains important theological values, such as holiness, justice, responsibility, and respect for human dignity, especially women, in the context of marriage. Although this text originates from the patriarchal culture of ancient Israel, its principles remain relevant in today's context. Regarding the phenomenon of early marriage, it was found that this practice often occurs without adequate preparation, whether emotional, spiritual, or economic, and thus risks causing various problems in the household. Therefore, the church has a responsibility to raise congregational awareness through faith formation, premarital education, and contextual pastoral care. This study confirms that marriage is a life calling that requires maturity and serious commitment, not simply a solution to social problems.

Academic stress is one of the common problems students face due to various learning demands, such as piling up assignments, pressure to achieve, and difficulty managing study time. This study aims to describe the concept of handling academic stress in students at SMA Negeri 1 Panyabungan through Islamic guidance and counseling. The research uses a qualitative descriptive approach with data collection techniques in the form of interviews with teachers involved in guidance and counseling services at the school. The results of the study show that academic stress in students is marked by decreased concentration in studying, frequent lateness, not completing assignments, and a lack of motivation to study. The dominant contributing factors are lack of rest, academic pressure, and suboptimal self-management skills. Handling this is done through giving Islamic advice, study motivation, religious coaching, as well as guidance from both guidance counselors and teachers. The handling is done through giving Islamic advice, study motivation, religious guidance, and support from school counselors and religious teachers. The Islamic guidance and counseling approach is considered able to help students gain peace, increase study motivation, and form more positive behaviors in facing academic demands.

The method used was a descriptive quantitative approach with a one group pre-test post-test design involving 54 students as participants. The instrument used was a questionnaire administered before and after the educational session. The educational materials included the definition, types, impacts, and prevention efforts related to Bullying and child harassment in the school environment. The results showed an increase in students’ knowledge and awareness regarding the importance of preventing Bullying and child harassment in schools. Therefore, educational programs conducted through the KKN activity can be one of the efforts to create a safe and Bullying-free school environment.

This study aims to analyze the strategic management evaluation of the Sundanese Language Subject Teacher Forum (MGMP) in improving teacher performance at public senior high schools in Tasikmalaya City. The study focuses on leadership management, member participation, institutional support, and program relevance to teachers’ professional development needs. This research employed a qualitative descriptive approach. Data were collected through observations, in-depth interviews, and documentation involving MGMP administrators, member teachers, school principals, and supervisors. Data analysis used the Miles and Huberman interactive model, including data reduction, data presentation, and conclusion drawing. The findings revealed that the MGMP management has generally functioned effectively as a professional learning community. Participatory leadership patterns encouraged collaboration among teachers in designing learning tools and solving classroom problems. However, several challenges were identified, including inconsistent program evaluation, limited technological integration, unequal member participation, and insufficient funding support. The study also found that MGMP programs significantly contributed to improving teachers’ pedagogical competence, especially in lesson planning and instructional implementation. Nevertheless, assessment and evaluation competencies still require further strengthening. This study concludes that strategic management, sustainable evaluation, and institutional support are essential in optimizing MGMP functions to improve teacher performance and the quality of Sundanese language learning.

Environmental damage caused by human activities has become an increasingly pressing global issue. Poetry as a literary work has the power to represent ecological problems symbolically and critically. This study aims to describe the representation of the impact of the environmental crisis in Taufiq Ismail's poems, namely "Menengajah Ke Atas, Merenungi Ozone yang Tak terlihat" and "Membaca Tanda-Tanda." The analysis is based on Greg Garrard's ecocritical study. This study uses a qualitative method with content analysis techniques. There are two stages of analysis, namely the literal and symbolic meaning of the poems, then an ecocritical interpretation is carried out based on Garrard's categories which include pollution, wilderness, apocalypse, dwelling, animals, and earth. The results of the study indicate that both poems represent the impact of the environmental crisis through health problems due to pollution and radiation, damage to water and forest ecosystems, climate change, threats to human living space, and the decline in biodiversity. The research findings also show that the most dominant categories are pollution and apocalypse, which confirms that the environmental crisis in Taufiq Ismail's poems is the result of human behavior that ignores nature. Thus, Taufiq Ismail's poems not only function as aesthetic works, but also as cultural criticism and moral warnings for humanity.
