Strengthening transparency and accountability in the financial management of Village-Owned Enterprises (BUMDes) is crucial in promoting good village governance. However, many BUMDes still face challenges such as weak record-keeping systems, the absence of internal audits, and limited human resource competencies in financial aspects. This community service activity aims to build an internal audit system as a strategy to improve the financial governance of BUMDes in Pematang Serai Village, Tanjung Pura Sub-District. The approach used is Community-Based Participatory Action Research (CBPAR), which emphasizes active community involvement throughout the process. The stages of the activity include problem identification, internal audit and basic accounting training, preparation of financial SOPs, implementation of the initial audit, and evaluation of the results. The results show that BUMDes administrators are able to independently conduct internal audits, compile cash reports and transaction documentation more systematically, and present the results in village deliberation forums. This activity also succeeded in increasing the capacity of administrators to compile simple digital reports using Excel. Community participation also encouraged the formation of a new culture that is more transparent and open to the process of managing village finances. This activity not only produced administrative outputs but also created institutional transformation that promotes more integrity-based BUMDes governance. The educational-participatory approach in internal audits has proven effective and is feasible to be replicated in other villages with similar conditions as part of efforts to strengthen good governance at the local level.

Loneliness is a subjective emotional experience commonly observed during emerging adulthood (ages 18–25). In this phase, shifts in emotional and affiliative needs may increase vulnerability to loneliness, particularly in the absence of intimate relationships. One intrapersonal factor influencing loneliness is attachment style, emotional bonding patterns formed in early childhood that shape the quality of interpersonal relationships in adulthood. This study aims to examine the relationship between attachment style and loneliness among emerging adults who are not currently in romantic relationships. A quantitative correlational method was employed using purposive sampling, involving 208 unmarried participants aged 18–25 who were not in romantic relationships. The instruments used were the Indonesian version of the Attachment Style Questionnaire (ASQ) and the UCLA Loneliness Scale Version 3. Spearman correlation analysis revealed a significant negative relationship between secure attachment and loneliness (r = -0.748**, p < 0.01), and a significant positive relationship between fearful attachment and loneliness (r = 0.273**, p < 0.01). No significant associations were found for preoccupied or dismissing attachment styles. These findings highlight the important role of attachment style in shaping loneliness experiences among young adults who are not romantically involved.

Education is the learning of knowledge, skills, and habits of a group of people that are passed down from one generation to the next through teaching, training, or research. Education often occurs under the guidance of others, but is also possible autodidactically. The etymology of the word Education comes from the Latin "Educare" which means "to educate" or to nurture, learning motivation is the desire that arises in students that causes learning activities to occur. The existence of learning motivation will ensure the sustainability of learning activities and provide direction to learning activities so that the goals desired by the learning subject can be achieved. And intrinsic value refers to the actual and fundamental value of a learning, and intrinsic value is used in learning in the formation of student values ​​in the ongoing learning process, in this study involved 306 student respondents from all over the Jabodetabek area with the value of the regression test measured into the coefficient b result of 0.286 for every 1% addition it will increase by 1,060 which is measured in the regression value equation Y = 0.286 - 1.060 and also the criteria for adding ha at 0.000 which means less than 0.05 which means there is no significance in the regression test properly.

This study aims to determine the relationship between perfectionism and academic burnout among final-year students in Jakarta. Academic burnout is defined as stress arising from the learning process that results in emotional exhaustion, depersonalization, and low academic performance (Sagita & Meilyawati, 2021). Perfectionism is considered a personality disposition characterized by concerns about self-evaluation, overly critical self-assessment, and striving to achieve perfect personal standards (Hill, 2017). This study employs a quantitative approach, involving final-year university students in Jakarta aged 20–25 years who are in their 7th–9th semesters. The sampling technique used is purposive sampling. The measurement tools used were the Multidimensional Perfectionism Scale developed by Flett and Hewitt (1991) and the School Burnout Inventory developed by Salmela-Aro, Kiuru, Leskinen, and Nurmi in 2009. The results of the correlation test using Pearson Correlation yielded a value of r = 0.854, with significance 0.000 p < 0.05. These results indicate that there is a relationship between perfectionism and academic burnout among final-year students in Jakarta. Based on the correlation test per dimension, the results show that there is a relationship between perfectionism and all dimensions of academic burnout, especially the exhaustion dimension. Additionally, there is a relationship between academic burnout and all dimensions of perfectionism, particularly the socially prescribed perfectionism dimension. This indicates that the higher an individual's level of perfectionism, the higher their level of academic burnout.

Stunting is a chronic nutritional problem that has a long-term impact on physical growth, cognitive development, and the quality of human resources in the future. This study aims to determine the relationship between family income and nutritional status of toddlers on the incidence of stunting in the Bukit Cening Daik Health Center working area, Lingga Regency, 2024. This study used a cross-sectional design with a sample size of 62 respondents selected through purposive sampling technique. Data were collected using questionnaires and anthropometric measurements, then analyzed using the chi-square test. The results of the analysis showed that there was a significant relationship between family income and nutritional status of children under five with the incidence of stunting (p < 0.05). This finding suggests that economic conditions and nutritional status play an important role in preventing stunting. Therefore, nutrition interventions targeting low-income families need to be strengthened to reduce stunting in the area.  

Infant mortality rates (IMR) at the global and national levels occur mostly during the neonatal period. One way to reduce infant mortality is to provide the best food, namely breast milk. The breastfeeding process can be hampered due to several problems, one of which is the occurrence of breast milk dams. The purpose of the study was to determine the relationship between mothers' knowledge about breastfeeding techniques and breast milk dams at PMB Pratiwi Agustian. The research method used was a quantitative analytic study with a cross sectional design. The research sample was 28 respondents using total sampling technique. Data were collected through questionnaires and analyzed using the chi-square test. The results showed that the majority of breastfeeding mothers with good knowledge of breastfeeding techniques did not experience breast milk dams as many as 5 people (71.4%), 13 people (76.5%) did not experience breast milk dams in the moderate category, and 4 people (100.0%) experienced breast milk dams in the poor category. Correlation analysis showed that there was a relationship between knowledge of breastfeeding techniques and breast milk dams in nursing mothers at PMB Pratiwi Agustian with a significant value of p = 0.015. Lack of knowledge about proper breastfeeding techniques can increase the risk of breast milk dams in mothers. Therefore, improving mothers' knowledge and skills in breastfeeding through proper education and counseling is crucial to prevent or reduce the incidence of breast milk dams.

The leading causes of maternal mortality are thought to include hemorrhage, sepsis, obstructed labor, and hypertensive disease of pregnancy. For many years, demographic and health surveys have been used to study maternal and perinatal health in developing countries. However, few nationwide population surveys have used formally validated questionnaires. Objectives: The purpose of this study was to determine the validity of maternal self-reports of obstetrical complications. Methods: A cross-sectional study was conducted among 300 women at Two Hospitals and one public health center. A questionnaire recorded mothers’ perceptions of obstetrical complications while hospital medical records. Sensitivity, specificity, predictive values, and percent agreement were obtained for obstetrical conditions. Result: In general, women’s reports of obstetrical complications did not match medical diagnoses. The highest agreement was obtained for reporting eclampsia, with less agreement for postpartum haemorrhage. Conclusion: The validity of the survey questionnaires varies between studies due to differences in the questionnaires. Health surveys based on maternal self-report must be interpreted with consideration of this limitation.

Toxic professional relationships—characterized by subtle exclusion, politicized decision-making, and emotional suppression—are a prevalent yet underexamined concern in academic institutions. This research emphasizes the psychological, pedagogical, and emotional repercussions for educators in situations characterized by workplace conflict, in contrast to prior studies that primarily examine structural factors. The study seeks to examine how educators perceive, interpret, and react to toxic dynamics, especially via reflective processes. We gathered data from three years of anonymized reflective journaling employing a qualitative, narrative-reflective methodology and conducted a theme analysis. Research highlights three main themes: the emotional effort needed to maintain professionalism despite feeling excluded, changes in teaching methods as a way to resist and find meaning, and how reflective practice helps teachers stay true to their teaching values. The analysis further demonstrates how gender and early-career status exacerbate susceptibility to toxic dynamics. The study prioritizes ethical contemplation as a transforming practice and a means of action instead of providing prescriptive solutions. Institutions should implement emotional intelligence training, equitable task allocation, and peer support mechanisms to cultivate more equal academic settings. This research advocates for a work culture founded on explicit performance expectations, mutual respect, compassion, and integrity in education, facilitating a deeper comprehension of teachers' authentic experiences in challenging school environments.
