Coal is an important energy source that is still widely used in industry, especially the power generation industry, because of its high energy content. However, in the process of handling and storage, coal has the characteristic of being easily oxidized, This oxidation process, if it occurs continuously, can cause internal heat accumulation which eventually triggers spontaneous combustion. This study aims to analyze changes in coal quality before and after spontaneous combustionto find out how spontaneous combustionaffects coal quality in stockpiles. The research method used is a quantitative method where the data from laboratory tests on coal quality before and after spontaneous combustionis analyzed, the comparison of coal quality in stockpile 10 before and after spontaneous combustionis then graphed to see changes in the quality of each parameter. Based on the results of the analysis of changes in coal quality before and after spontaneous combustion, there were significant changes to several coal quality parameters, namely Total Moisture which was originally from 7.06% to 5.50% (down by 1.56%), Moisture which was originally 3.91% to 3.22% (down by 0.69%), Ash Content which was originally 8.84% to 14.67% (up by 5.83%), Volatile Matter which was originally 39.77% to 35.10% (down by 4.67%),  Fixed Carbon from 47.48% to 47.01% (down by 0.47%), Sulphur from 0.55% to 0.46% (down by 0.9%), and Calorific value decreased from 6,921 to 6,289 kcal/kg (down by 632 kcal/kg). This decrease in quality has a direct effect on the selling value and efficiency of coal combustion. The existence of an analysis of changes in coal quality due to spontaneous combustioncan help companies to find out how much of an impact losses can be caused by the occurrence of spontaneous combustion. By considering the potential losses due to spontaneous combustion, the company will make efforts to prevent the occurrence of spontaneous combustion in the future to minimize the losses caused.

Waste candlenut shells are one type of biomass that has significant potential to be developed as an alternative energy source, particularly in the form of briquettes. Candlenut shells, which are typically discarded as agricultural waste, contain combustible material that can be transformed into solid fuel. However, the traditional briquette molding process is still done manually, which is time-consuming, inefficient, and often results in inconsistent briquette shapes and density. This study aims to design and develop a briquette molding machine specifically for processing candlenut shell waste, with the goal of improving both production efficiency and the quality of the briquettes produced. The research methodology includes several stages: mechanical design, selection of appropriate materials, fabrication of machine components, assembly, and performance testing of the machine. The resulting machine utilizes a screw conveyor compression system powered by a 5.5 HP petrol engine. It features a cylindrical mold with a 40 mm diameter to shape the briquettes uniformly. During the performance test, the machine demonstrated a maximum production capacity of 14.3 kg per hour, with an average processing time of 24 minutes and a briquette yield reaching up to 85%. The findings indicate that the machine can significantly streamline the briquette production process while maintaining product consistency and quality. This briquette molding machine is particularly suitable for household and small-scale industries aiming to utilize renewable energy sources and reduce dependency on fossil fuels. The use of this machine also supports environmental sustainability by converting agricultural waste into a usable energy product.  

Indonesia, a country located in the Pacific Ring of Fire, has a high level of vulnerability to earthquakes. This condition demands an increase in the capacity of civil engineering human resources to design safe and disaster-resistant buildings. This study aims to evaluate the effectiveness of project-based learning training with a focus on the application of SNI 1726:2019, structural modeling using ETABS/RSA, lateral load calculations, and the design of simple earthquake-resistant houses. The research method involved final-year civil engineering students and alumni who participated in a series of trainings, with evaluations through pre-tests, post-tests, and design assessments. The results showed an increase in competency in all aspects, especially the understanding of the SNI 1726:2019 standard and lateral load calculations. In addition, participants were able to produce simple house designs that meet the basic criteria for earthquake resistance, material efficiency, and structural stability. These findings indicate that applied training can bridge the gap between academic theory and practical skills needed in the workplace. This research contributes to strengthening the capacity of civil engineering in supporting resilient infrastructure development and has important implications for the integration of similar training into higher education curricula and community service programs.

Drug abuse among adolescents in Jayapura City is a pressing issue with significant repercussions for health, society, and the future of younger generations. Due to Jayapura's strategic position as a border city with Papua New Guinea, it faces a heightened risk of cross-border drug trafficking, making it particularly vulnerable. This study explores the various factors contributing to the rise in drug abuse among adolescents, including individual, family, and peer group dynamics, socio-economic conditions, weak legal enforcement, and the influence of globalization. The findings suggest that a multifaceted approach is essential in addressing the problem. Repressive measures alone are insufficient, and should be complemented by preventive, rehabilitative, and educational strategies. Such approaches must emphasize child protection principles and ensure justice that is both substantive and forward-thinking. Progressive and responsive legal frameworks, aligned with the goals of criminal punishment, are necessary to effectively combat drug abuse in Jayapura. Moreover, these frameworks should prioritize adolescent recovery, recognizing that these individuals are the future of the nation.

This study aimed to evaluate the effect of broiler concentrate-based rations combined with corn and rice bran on the performance of native chickens. A total of four dietary treatments were formulated, namely P1 (100% broiler concentrate), P2 (75% broiler concentrate, 10% corn, 15% rice bran), P3 (50% broiler concentrate, 30% corn, 20% rice bran), and P4 (25% broiler concentrate, 55% corn, 20% rice bran). The parameters observed included feed intake, body weight gain, and feed conversion ratio (FCR). Data were analyzed using analysis of variance (ANOVA), and significant differences among treatments were further tested with Duncan’s New Multiple Range Test (DMRT). The results showed that dietary treatments significantly affected the growth performance of native chickens (P<0.05). Chickens fed diets with higher proportions of broiler concentrate (P1 and P2) exhibited better body weight gain and more efficient feed conversion compared to those receiving lower concentrate levels (P3 and P4). In contrast, increasing corn and rice bran levels tended to increase feed intake but did not proportionally improve body weight gain, resulting in poorer FCR. It can be concluded that native chickens perform optimally when fed rations containing at least 75% broiler concentrate, which provides a balance between growth and feed efficiency.

This study aims to analyze the growth of tilapia (Oreochromis niloticus) cultivated in a concrete pond system in Dusun IV, Fadoro Lasara Village, Gunungsitoli City. The concrete pond system was chosen for its advantages in land efficiency, ease of management, and ability to maintain stable water quality. The research method employed a quantitative experimental approach over 60 days, with 200 Nile tilapia as the study subjects. The parameters observed included absolute weight and length gain, specific growth rate (SGR), feed conversion ratio (FCR), and survival rate (SR). The results showed that the average weight of the fish increased from 5.12 grams to 98.46 grams, with a length increase of 12.5 cm. The SGR was recorded at 4.29% per day, FCR at 1.38, and SR at 96.5%. These results indicate that the concrete pond system can support optimal tilapia growth. This study recommends the application of concrete ponds as an efficient aquaculture alternative, particularly in areas with limited land and resources. This system has proven to be adaptive to local conditions and contributes to increased productivity and income for aquaculture farmers.

This study examines the role of the hula-hula authority within the Batak Toba kinship system, known as Dalihan na tolu, and its relevance to the theological understanding of blessings. In Batak tradition, hula-hula is viewed as "Debata na tarida" (the visible God) and is considered a source of blessings in various social and ritual contexts, especially through the practice of giving ulos. However, Christian doctrinal theology asserts that blessings are solely a gift from God, independent of any specific social structure or tradition. Using a qualitative research method through literature study, this paper explores the intersection and tension between Batak customs and Christian theology. The findings show that while the authority of hula-hula enriches the values of social harmony and kinship ethics, this understanding risks overshadowing the biblical truth that God is the sole source of blessings. Therefore, the church is called to reaffirm God's authority while also respecting cultural values. This study highlights the tension between tradition and theology, which should be addressed with wisdom to allow both to coexist harmoniously.

The level of anxiety during competition needs to be considered because it can interfere with the athlete's focus, cause difficulty in controlling movements, reduce the quality of the game, and hinder the application of strategies, which overall has a negative impact on athlete performance. This study was motivated by the observation of researchers who found that there were still many athletes experiencing symptoms of anxiety, such as cold sweaty hands and nausea. The research method used was a survey with Nyak Amir's Sport Anxiety Scale (SAS) questionnaire consisting of 22 statement items. The subjects of this study were 20 athletes who had met the criteria and were analyzed using descriptive statistics with Microsoft Excel and SPSS. The results of the research on the anxiety of Dukati Taekwondo Club athletes before the match were in the “rather low” category with an average score of 41.25. However, if analyzed further based on aspects of anxiety, there are differences in anxiety levels in each aspect. The somatic aspect has the highest anxiety with a score of 15.5, showing physical symptoms such as heart palpitations and body trembling. Motor aspects with a score of 14.75, affective with a score of 5.45, and cognitive 5.55 were mostly in the moderate category, reflecting muscle tension, feelings of anxiety, and negative thoughts before competing.  

This study is grounded in the importance of equipping prospective teachers with professional competencies required in the digital era. The Kampus Mengajar program provides students with practical teaching experiences through direct involvement in schools, while mastery of TPACK is essential for designing instruction that aligns with contemporary educational demands. The purpose of this research is to examine the influence of participation in the Kampus Mengajar program and TPACK mastery on the teaching readiness of students in the Faculty of Pedagogy and Psychology at Universitas PGRI Wiranegara. The study adopts the TPACK framework, which integrates content, pedagogy, and technology. Using a quantitative associative design, the research involved 86 respondents from cohorts 5 to 8 of Kampus Mengajar participants. Data were analyzed through multiple linear regression. The findings indicate that participation in the Kampus Mengajar program has a positive and significant effect on teaching readiness (t = 3.132 > t-table 1.989; sig. = 0.002). Likewise, TPACK mastery significantly influences teaching readiness (t = 8.520; sig. = 0.000). Simultaneously, both variables show a significant effect on teaching readiness (F = 103.752 > F-table 3.105; sig. = 0.000). The study concludes that engagement in Kampus Mengajar and TPACK competence, both individually and jointly, contribute to preparing students for the teaching profession. These results highlight the need for higher education institutions to strengthen practical programs and foster the integration of pedagogy and technology in teacher education.

In an ever-evolving digital era, the protection of human rights has become an increasingly complex and urgent challenge. Digital constitutionalism emerges as an innovative and necessary framework to address this challenge, integrating human rights principles into technology-based state governance. This journal aims to explore how digital constitutionalism can strengthen the protection of human rights while analyzing the challenges and opportunities faced in its implementation. Through a qualitative analysis approach, this research collects and analyzes relevant literature as well as case studies from various countries that have adopted the principles of digital constitutionalism. The findings indicate that while digital constitutionalism offers significant potential to enhance human rights protection, substantial challenges such as privacy, data security, and access to information still need to be addressed. Furthermore, the role of government, civil society, and the private sector is crucial in creating an environment that supports the protection of human rights in the digital space. The conclusion of this research emphasizes the importance of cross-sector collaboration to ensure that human rights are not only constitutionally recognized but also effectively protected in practice. Thus, digital constitutionalism serves not only as a tool for safeguarding human rights but also as a driver for creating a more transparent, accountable, and responsive governance system to meet the needs of society in the digital era.

The Memorandum of Understanding (MoU) is a preliminary agreement in contracts established under the Common Law system, and this research is based on the increasing phenomenon of using MoUs as an initial form of agreement in various fields, including the organization of beauty pageants; however, in practice, there remains ambiguity regarding the extent to which an MoU has binding legal force, particularly when one party commits a breach of contract or when disputes arise, thus this study formulates two main issues, namely the legal status of the parties involved in the MoU of the Miss Beauty East Java 2022 pageant agreement and the legal consequences of the non-performance of such MoU, employing a normative juridical method through statute, conceptual, and case approaches to analyze the practice of MoUs in Miss Beauty East Java 2022, and the findings indicate that although MoUs are not explicitly regulated in the Indonesian Civil Code, they may be considered preliminary agreements subject to the principle of freedom of contract under Article 1338 of the Civil Code, with the legal status of the parties being binding as long as the MoU fulfills the essential elements of a valid contract (agreement, legal capacity, specific object, and lawful cause), while the legal consequences of non performance may give rise to legal liability resolved through non-litigation efforts such as mediation or arbitration, or ultimately through litigation if amicable settlement fails, leading to the conclusion that the MoU in the Miss Beauty East Java 2022 pageant possesses binding legal force as a preliminary agreement rather than merely a moral commitment, provided that it is clearly drafted and meets the validity requirements of a contract under Indonesian law.

Mosques play a strategic role as centers of worship and community development at the local level, serving not only as places of worship but also as spaces for non-formal religious education. However, many rural mosques are experiencing declining functionality due to limited facilities, human resources, and a lack of sustainable programs. This condition is evident in the Al-Karomah Mosque in Kalibundar Hamlet, where religious activities have declined due to the lack of sustainability of the Al-Qur'an Education Park (TPA) program. This community service activity aims to revitalize the function of the mosque by strengthening the TPA by emphasizing the instilling of religious moderation values ​​and increasing community participation. The method used is Participatory Action Research (PAR) involving mosque administrators, TPA teachers, community leaders, and parents of students through observation, interviews, and documentation of activities. The program implemented includes improving TPA management, teacher training, developing a simple curriculum based on religious moderation, and reactivating Quran recitation activities and habituating worship. The results of the activity indicate an increase in interest in learning the Quran, strengthening the values ​​of tolerance and togetherness, increasing community participation, and growing awareness of the importance of religious moderation. Thus, revitalizing prayer rooms through strengthening TPA is effective in strengthening religiosity while building social harmony based on religious moderation. The method used in this article is Participatory Action Research (PAR), involving mushola management, TPA teachers, community leaders, and parents of students through field observations, interviews with religious figures, and activity documentation. Program activities include improving TPA management, teacher training, developing a simple curriculum based on religious moderation, and reactivating Qur’anic learning and regular worship activities. The results of the program show: (1) increased interest in learning the Qur'an among children and youth, (2) strengthened values of tolerance, togetherness, and social awareness, (3) growing community participation in religious activities, (4) the role of the mushola as a center of religious moderation at the hamlet level, (5) increased participation of students and community members, (6) rising awareness of the importance of religious moderation, and (7) the reestablishment of Mushola Al-Karomah as a center of community religious activities. Thus, revitalizing the mushola through the TPA has proven effective in strengthening religious values while building social harmony based on religious moderation

This study aims to analyze the effect of changes in interest rates, exchange rates, economic growth, and world oil prices on stock returns in the transportation and logistics sector in Indonesia during the period 2006–2024. This sector was chosen because it is highly vulnerable to fluctuations in macroeconomic factors that have a direct impact on companies' operating costs and financial performance. The method used is multiple linear regression with an annual panel data approach, using a sample of transportation and logistics companies listed on the Indonesia Stock Exchange. The independent variables include changes in interest rates, exchange rates, economic growth, and oil prices, while the dependent variable is stock returns. The results show that, partially, only changes in interest rates have a significant negative effect on stock returns. Conversely, exchange rates, economic growth, and oil prices have no statistically significant effect. Simultaneously, these four variables also show no significant effect on stock returns. This study makes a new contribution through the use of a long observation period and a focus on the transportation and logistics sector, thereby providing a deeper understanding of this sector's sensitivity to macroeconomic conditions.

One of the most common problems that occurs for MSMEs is in their development. Therefore, it is necessary to pay attention to business performance in order to be able to survive and excel in competition. This study aims to test the influence of human resource competence, financial literacy, financial capital, and social capital on the performance of MSMEs in Tempel District, both partially and simultaneously. The research approach uses a quantitative method with questionnaire instruments distributed to 99 respondents of MSME actors through non-probability sampling techniques. Data analysis was carried out using the SEM-PLS method with the help of SmartPLS 4.1.0.9 software, through outer model testing (validity and reliability test) and inner model (VIF, GoF, R2 test and hypothesis test). Hypothesis testing is carried out through the t-test and the f-test. The results of the study show that partially human resource competence, financial literacy, and financial capital have a significant positive effect on the performance of MSMEs, while social capital has a positive but insignificant effect on the performance of MSMEs. The results of the research simultaneously show that human resource competencies, financial literacy, financial capital, and social capital have a significant effect on the performance of MSMEs. The implications of these findings emphasize the need for strategies to strengthen human resource competence, increase financial literacy, optimize financial capital, and develop social capital to strengthen the competitiveness and sustainability of MSMEs in the research area.

Indonesia is a country with a high level of labor-related issues, particularly in relation to the protection and fulfillment of workers’ rights. Common problems include termination of employment, unpaid wages, and inadequate severance payments. One such case is the bankruptcy petition filed against PT. Setiaji Mandiri, which serves as the focus of this study. The objective of this research is to analyze the legal considerations behind the Commercial Court’s decision to grant the bankruptcy request and its implications for labor rights. This study employs a normative juridical method by analyzing relevant legislation and court rulings, particularly referring to Law No. 37 of 2004 on Bankruptcy and Suspension of Debt Payment Obligations, and Law No. 2 of 2004 on Industrial Relations Dispute Settlement. The findings show that PT. Setiaji Mandiri had indeed made efforts to settle its financial obligations, but these efforts were deemed insufficient by the court, leading to the acceptance of the bankruptcy petition. However, a key issue that emerged was the absence of debt registration with the Industrial Relations Court (PHI), which is mandated by law in cases involving employment disputes. According to the prevailing labor laws, the PHI must first determine the amount of severance pay owed to employees, which can then be used as a reference in bankruptcy proceedings. The study concludes that there was a procedural oversight in the handling of labor claims in this bankruptcy case. It emphasizes the importance of adhering to legal mechanisms that protect workers’ rights and recommends stricter coordination between commercial and labor courts to prevent similar issues in the future.

The development of wearable technology, especially smartwatches, opens up great opportunities in preventive health monitoring, especially in rural areas such as Sembung Village, Wringinanom, Gresik, where access to health services is limited. However, this technology is still alien to the local community. Preliminary surveys show that the majority of citizens, including health cadres, have never used or even seen a smartwatch in person, and view it as a luxury and irrelevant item. In fact, the potential of smartwatches as “digital health assistants” is huge from tracking heart rate, blood oxygen levels (SpO₂), stress levels, to physical activity reminders that are essential for early detection of health disorders. This service activity aims to improve digital literacy and adoption of smartwatch technology through a participatory educational approach and direct assistance. Implementation methods include: (1) coordination with the village government and health workers, (2) Interactive socialization using local languages, (3) step-by-step practical training, (4) simulation of application in the field, and (5) pre-test and post-test evaluation of 27 participants (25 health cadres, 1 midwife, 1 nurse). The results showed significant improvements: function understanding from the original value of 1.8 increased to 4.2, consumption interest from the original value of 2.1 increased to 4.0, benefit perception from the original value of 1.9 increased to 4.3, self confidence from the original value of 1.5 increased to 3.8, and digital literacy awareness from the original value of 2.0 increased to 4.1. The hands-on approach proved effective in changing participants ' mindset from skeptical to enthusiastic, proving that the digital divide is not due to incompetence, but the lack of access to contextual education. The implication is that smartwatch has the potential to become a strategic tool for village health cadres in early detection and real-time data-based health education, provided that it is supported by sustainable mentoring.

The spirituality of today’s church youth encounters multidimensional challenges, particularly the pervasive influence of digital culture, the gradual decline in interest toward spiritual disciplines, and the weakening of involvement in ecclesial ministry. Such dynamics often create a gap between theological knowledge and lived faith experiences. This Community Service (PkM) initiative was designed to respond to these issues by implementing an interactive model aimed at enhancing the spiritual understanding of the youth at GKSI Trimorejo Congregation. The model emphasizes participatory learning processes, in which youth are not merely passive recipients of teaching but active contributors to collective faith formation. The methodological framework consisted of three main stages: initial observation to identify needs and spiritual conditions; preparation of training modules contextualized with the congregation’s realities; and the implementation of interactive activities such as group discussions, thematic Bible studies, role-play, and collective reflection. Evaluation strategies integrated both quantitative and qualitative approaches, including pre-tests and post-tests to measure cognitive growth, alongside participatory interviews to capture experiential insights. The findings reveal a notable increase in youth comprehension of biblical principles, heightened enthusiasm and participation in church programs, and the establishment of a more cohesive spiritual learning community. Furthermore, the process encouraged a deeper sense of belonging and responsibility among the participants toward their ecclesial environment. In conclusion, the interactive model demonstrates significant effectiveness in fostering youth spirituality and may serve as a viable alternative strategy for churches encountering similar challenges within contemporary contexts of ministry.
