Illegal mining activities in Sebulu District have become a serious issue as they not only violate the law but also cause significant damage to public infrastructure such as village roads, bridges, and drainage systems, which are deteriorating due to heavy trucks transporting mining materials. Although Article 158 of Law Number 3 of 2020 concerning Mineral and Coal Mining stipulates strict sanctions, law enforcement remains weak. The main contributing factors are local community involvement, inadequate supervision by authorities, and social legitimacy that perceives mining as a normal activity. This study aims to analyze criminal liability for illegal mining offenders and to identify its social and environmental impacts in Sebulu District. The research applies a socio-legal approach that combines normative and empirical methods. The normative approach examines applicable legal provisions, while the empirical approach includes field observations, interviews with local officials and residents, and documentation of relevant regulations and events. The findings indicate that the most severe impacts are the deterioration of village roads and bridges and environmental degradation, such as changes in water color in nearby drainage channels. These conditions cause public concern and disrupt daily life. Weak law enforcement allows illegal mining to persist. Therefore, synergy among law enforcers, local government, and communities is needed to strengthen regulation enforcement and develop sustainable economic alternatives.

This study aims to analyze the influence of digital transformation and work environment on employee performance at the Energy and Mineral Resources Office of East Kalimantan Province. Digital transformation is a crucial element in promoting bureaucratic efficiency and public service quality, while a conducive work environment plays a vital role in enhancing employee motivation and productivity. A quantitative approach was applied using a survey method with a census of 68 employees. The data were analyzed using multiple linear regression with SPSS version 22. The results show that both digital transformation (t = 4.401; sig. = 0.000) and work environment (t = 2.126; sig. = 0.037) have a positive and significant partial effect on employee performance. Simultaneously, the variables also have a significant influence (F = 114.254; sig. = 0.000). The coefficient of determination (R² = 0.780) indicates that 78% of the variation in employee performance is explained by these two factors. These findings emphasize the importance of implementing effective digital systems and creating a supportive work environment to optimize bureaucratic performance in the public sector

Termination of employment is one of the most common occurrences in industrial relations. In practice, the implementation of workers' rights after termination, particularly those related to severance pay, does not always proceed in accordance with applicable legal provisions or mutually agreed terms. This study aims to analyze the settlement of remaining severance pay claims based on an agreement between the workers and PT. Nusa Halmahera Minerals. This study uses a normative juridical method with a Data was obtained through literature studies, legislation, and mutual agreement documents. The results of the study show that there are delays and inconsistencies in the implementation of severance pay as stated in the mutual agreement. The settlement was mostly non-litigious through mediation at the Manpower Office, but did not result in the full fulfillment of rights. This shows the weak bargaining position of workers in the implementation of collective labor agreements, as well as the need to strengthen legal mechanisms for sanctions against companies that fail to fulfill their obligations.

This study examines the reclamation plan of PT. Z for the 2023–2027 period with the aim of assessing the technical feasibility, ecological effectiveness, and alignment with national reclamation regulations. A descriptive-quantitative approach was employed through field observations, analysis of geomorphological conditions, evaluation of topsoil management, assessment of revegetation performance, and review of key environmental documents. The planned land disturbance reaches 138.53 ha, with reclamation focused on the disposal and topsoil areas covering 29.67 ha, as the mining pit remains active. Reclamation activities include land recontouring, topsoil spreading, erosion control, establishment of Legume Cover Crops (LCC), and planting of local species such as Rukam. The results indicate that the implemented strategies effectively enhance soil stability, improve vegetation cover, and support ecosystem recovery. Furthermore, the reclamation program meets the key performance criteria set by the Ministry of Energy and Mineral Resources, with vegetation cover exceeding 90% and stable slope conditions. Challenges remain, particularly related to sedimentation management and the absence of pit reclamation during the active mining phase. Overall, the study concludes that PT. Z has developed and executed a reclamation plan that reflects good mining practices and environmental stewardship, contributing to the long-term sustainability of post-mining land use.

Legal uncertainty in the implementation of the carbon tax poses significant challenges to Indonesia’s investment climate, particularly in the non-renewable energy sector. This study aims to examine how the postponement of carbon tax implementation, despite the operation of carbon trading instruments, affects foreign investors’ expectations from the perspective of investment law. The research employs a normative juridical (dogmatic) approach combined with a light event study on major policy milestones between 2021 and 2023, including Presidential Regulation No. 98/2021, Ministerial Regulation of Energy and Mineral Resources No. 16/2022, OJK Regulation No. 14/2023, the launch of IDXCarbon, and the announcement of the carbon tax delay until 2025. The findings reveal varied market responses in fossil-based utility firms’ stocks and bonds, indicating the presence of an uncertainty premium. From a legal standpoint, the asymmetric configuration between delayed fiscal instruments and the ongoing non-fiscal instruments potentially undermines the principle of legal certainty under Investment Law No. 25/2007, while also raising risks related to Fair and Equitable Treatment (FET) and legitimate expectations. Nevertheless, the state’s right to regulate remains a crucial foundation for balancing investor protection with the imperative of energy transition. This study underscores the importance of policy consistency and transparency to maintain investment attractiveness and strengthen the legitimacy of Indonesia’s climate regulation.  

Mining activities in Mandailing Natal Regency, particularly in Kota Nopan, Huta Bargot, and Batang Natal Districts, play a significant role in the local economy while simultaneously generating complex legal, environmental, and social problems. Despite the existence of comprehensive national regulations such as the Mineral and Coal Mining Law and regional bylaws, enforcement remains weak, as indicated by the persistence of illegal mining (PETI), environmental degradation, and conflicts of interest among various stakeholders. This study aims to analyze the dynamics of mining law enforcement by employing a juridical-empirical approach that combines the review of statutory regulations, secondary data, and field observations in three sample districts. The findings reveal that law enforcement is far from optimal due to structural constraints, including limited institutional capacity and inconsistent implementation, as well as cultural and economic factors, such as the community’s dependence on mining as a primary livelihood. Moreover, political and economic interests often weaken oversight and create selective enforcement, further widening the gap between regulation and practice. The study emphasizes that law enforcement in the mining sector should not rely solely on repressive measures but must be integrated with community empowerment, sustainable livelihood alternatives, and the strengthening of institutional governance. Therefore, reforming regional regulations, improving inter-agency coordination, enhancing law enforcement capacity, and ensuring active community participation are crucial steps to build legal, fair, and sustainable mining governance in Mandailing Natal.

Malnutrition is a condition in which the body does not receive enough essential nutrients, such as protein, vitamins, calories, and minerals, which causes various health problems, especially wasting and stunting, making it a serious concern in children. According to the Basic Health Research, the prevalence of malnourished children in Indonesia remained stable at 17.8% between 2016 and 2017 but decreased to 13.8% in 2018. This case study focuses on a 23-month-old girl from Kuala Keureuto Village, who was observed for three weeks through home visits in 2025. The diagnosis of malnutrition was made in accordance with national guidelines outlined in the Indonesian Minister of Health Regulation No. 2 of 2020, regarding child anthropometric standards. Anthropometric measurements showed that the child's height was 78.3 cm and her weight was 8.8 kg. Based on these measurements, her nutritional status was assessed as follows: A height/age Z-score between -2 and -3 SD indicates stunting, a weight/age Z-score between -2 and -3 SD indicates underweight, while a weight/age Z-score below -2 SD and a BMI/age Z-score below -2 SD are considered well-nourished. After confirming the diagnosis, the patient received nutrition education, supplemental feeding, appetite-stimulating supplements, and growth monitoring. In addition, analyses were conducted to identify factors influencing her condition, concluding that the malnutrition observed in this 23-month-old patient was influenced by parenting behavior, parental knowledge, medical history, incomplete immunizations, and environmental factors.

This service method uses Participatory Action Research (PAR) through the stages of to know (identifying problems), to understand (socialization of concepts), to plan (design a system from gallons of mineral water), to act (training and assistance in making hydroponics-aquaponic systems, making fish feed from household waste, and natural vitamins), and to change (evaluation and sustainability). As a result, there is an improvement in community skills with the realization of catfish harvest along with optimal kale growth, opening household business opportunities, and creating a sustainable empowerment model through appropriate technology transfer.

Acid mine drainage (AMD) is one of the major environmental problems arising from coal mining activities. AMD is formed through the oxidation of sulfide minerals, resulting in acidic water with high concentrations of dissolved heavy metals. This condition is characterized by elevated levels of Fe, Mn, and total suspended solids (TSS), which, if left untreated, can pollute nearby water bodies, damage aquatic ecosystems, and pose risks to human health. Therefore, effective, eco-friendly, and low-cost treatment methods are needed to minimize the negative impacts of AMD. This study aims to investigate the effect of activated carbon derived from sugarcane bagasse as an adsorbent for reducing Fe, Mn, and TSS levels in AMD at the sump of PT Alreksa Bara Mitra. The selection of sugarcane bagasse is based on its abundance as an agro-industrial waste and its high lignocellulosic content, making it a potential raw material for activated carbon. The research involved the preparation of activated carbon through carbonization and activation processes, followed by its application to AMD samples with variations in adsorbent dosage and contact time. Laboratory analyses were conducted to measure the concentrations of Fe, Mn, and TSS before and after treatment. The results showed that sugarcane bagasse-based activated carbon significantly reduced Fe, Mn, and TSS concentrations. The highest removal efficiencies were achieved under optimum conditions, reaching 93.14% for Fe, 95.05% for Mn, and 85.04% for TSS. These findings demonstrate that activated carbon from sugarcane bagasse has a strong adsorption capacity for dissolved metals and suspended solids in AMD. In conclusion, sugarcane bagasse-derived activated carbon has potential as an environmentally friendly and cost-effective alternative for AMD treatment, while simultaneously providing added value to agro-industrial waste. This research is expected to serve as a reference for the development of more sustainable mine wastewater treatment methods.

Employee loyalty is an important aspect in maintaining organizational sustainability, because high loyalty will have an impact on improving the company's performance and success in the long term. Factors such as job characteristics, work flexibility, and work motivation are thought to have an important role in influencing employee loyalty, especially in government agencies that demand high dedication. Therefore, this study was conducted to analyze the influence of job characteristics, work flexibility, and work motivation on employee loyalty at the Directorate General of Minerals and Mineral Resources of the Republic of Indonesia. This study used a quantitative approach with data collection techniques through questionnaires. The sampling technique used was non-probability sampling with a sample size of 90 respondents. Data analysis was carried out using multiple linear regression with the help of SPSS version 26 software, and supplemented with descriptive analysis of the primary data obtained. The results showed that the regression equation obtained was Y = 8.219 + 0.464X1 + 0.110X2 + 0.429X3. This equation indicates that job characteristics, work flexibility, and work motivation have a significant effect on employee loyalty. Partially, work flexibility is proven to have a positive and significant effect on employee loyalty. Similarly, work motivation also has a positive and significant partial effect on loyalty. This confirms that better job characteristics, greater flexibility, and stronger motivation mean higher levels of employee loyalty. This research implies that organizations need to consider job design, work system flexibility, and motivation-boosting strategies to build sustainable employee loyalty.

Pesidi Village, located in Grabag Subdistrict, Magelang Regency, is a highland region with promising potential in agriculture and livestock, particularly sheep farming. However, one of the major challenges faced by local farmers is the limited availability of forage during the dry season, coupled with the low utilization of agricultural by-products such as rice straw. These constraints often hinder livestock productivity and pose risks to feed security. To address this issue, a community service program was conducted with the aim of introducing and demonstrating local-based feed processing technologies, including silage, ammoniation, and Urea Mineral Block (UMB) production. The activity was implemented in several stages: problem identification, socialization, education, training, and monitoring of farmer implementation. Through this participatory approach, farmers were given hands-on training and practical guidance on processing alternative feed sources to ensure the availability of nutritious and sustainable livestock feed. The results showed that farmers began adopting UMB as a feed supplement due to its practicality and visible benefits in maintaining livestock health and productivity. However, silage and ammoniation methods were not yet widely adopted, mainly due to limited experience, lack of supporting equipment, and the perception that the processes were relatively complex. Despite these challenges, the program succeeded in raising farmer awareness of the importance of feed diversification and the optimization of agricultural waste. The training provided valuable insights into how the integration of silage, ammoniation, and UMB can increase feed efficiency, reduce dependency on fresh forage, and support sustainable livestock management. The implementation of these three technologies holds significant potential to enhance sheep farming productivity in rural highland communities, while simultaneously strengthening food security and supporting environmentally friendly agricultural practices.

This community service activity was conducted in Sawahan Hamlet, Mojotengah Village, Kedu District, Temanggung Regency, with the primary objective of enhancing the health and productivity of sheep through the introduction and production of mineral block molasses as supplementary feed. Mineral block molasses is a nutrient-rich feed supplement designed to meet the mineral requirements of ruminants, particularly sheep, which are often not fully met by conventional forage. The program was implemented using a participatory method, beginning with a lecture session that provided theoretical knowledge regarding the benefits, composition, and formulation of mineral block molasses. This was followed by an interactive discussion session in which participants, mainly local sheep farmers, were encouraged to share challenges and constraints they face in livestock feeding management. The facilitators then provided practical problem-solving approaches tailored to the local context. The final stage involved a hands-on demonstration of the step-by-step process of producing mineral block molasses, enabling participants to observe and practice directly. The results of this activity showed that participants not only gained new knowledge about the nutritional importance of mineral supplementation but also developed the practical skills necessary to independently produce mineral block molasses for their livestock. This is expected to improve feed efficiency, promote better animal health, and increase livestock productivity. Furthermore, the activity fostered community awareness of sustainable livestock management practices and the economic benefits of producing feed supplements locally. In conclusion, this program successfully empowered the local farming community with both theoretical and practical competencies in mineral block molasses production, contributing to improved livestock performance and farmer welfare. The continuation of such initiatives is recommended to ensure long-term adoption and optimization of livestock feeding practices in the region.

Limited sanitation facilities among street vendors, particularly those selling meatballs, chicken noodles, and porridge, often pose a problem that impacts food safety. One common practice is repeatedly washing bowls and spoons with just a bucket of water, followed by drying the utensils with a cloth. This contaminated water can transmit pathogenic microorganisms that cause foodborne illnesses, increasing the risk of health problems for consumers. This problem requires a practical solution that street vendors can implement, taking into account limited space, mobility, and operational costs. This community service activity used a pre-experimental design method with a simple technological engineering approach to improve the sanitation of tableware. The innovation developed was a portable bowl washer made from used mineral water gallons, modified to be mobile, efficient, and water-efficient. The manufacturing process included design, assembly, testing, and evaluation with street vendors. Success was measured by observing the level of cleanliness of the tableware before and after use, as well as assessing the level of satisfaction and ease of use by the vendors. The results showed that the implementation of this portable sanitation device increased the effectiveness of tableware washing, reduced the repeated use of dirty water, and minimized the risk of cross-contamination. Partnering vendors stated that the device is practical, lightweight, and doesn't disrupt their sales activities. They hope this innovation will be replicated by other vendors and that local governments will consider implementing it as a standard for mobile food sanitation. This effort will not only improve the hygiene of eating utensils but also contribute to preventing foodborne illnesses in the community.

Durian is a tropical fruit belonging to the climacteric group, meaning it experiences a surge in respiration after harvest and quickly deteriorates. Due to its perishable nature, processing is necessary to extend its shelf life and maintain its nutritional value and flavor. One traditional method of processing that has long been known in Indonesia, particularly in Kalimantan and Sumatra, is the fermentation of durian flesh into tempoyak. Tempoyak is a natural fermentation product made from ripe durian flesh that has undergone a further ripening process and has a distinctive sour taste and strong aroma. The tempoyak fermentation process involves the activity of microorganisms, particularly lactic acid bacteria (LAB) such as Lactobacillus plantarum and Lactobacillus curvatus, which play a crucial role in producing flavor, a semi-solid texture, and functional health benefits. Human food needs depend not only on the quantity of food but also on the quality of its nutritional content, such as carbohydrates, protein, fat, vitamins, and minerals. In this context, fermented foods such as tempoyak provide added value in the form of probiotics that have the potential to improve digestive health. Lactic acid bacteria, which dominate the natural fermentation process, play a crucial role in the formation of flavor compounds and beneficial biological activities. This study aimed to isolate and identify the types of LAB present in traditional tempoyak from Jambi. Isolation was conducted to obtain pure strains of bacteria with potential probiotics, while identification aimed to determine the dominant bacterial species in the tempoyak fermentation process. The results of this study are expected to contribute to the development of functional food products based on local fermentation.

The exploitation of natural resources through mining projects in Indonesia often has an impact on the lives of residents, both socially, economically, and environmentally. Although the government has established various regulations to protect the rights of affected communities, the implementation of this legal protection still faces various challenges. In this context, this research aims to analyze legal protection for residents in mining projects in Indonesia and examine the effectiveness of regulations that have been implemented. This research uses a normative juridical method using both a statutory and a conceptual approach. The former involves examining multiple legal provisions that govern mining and community protection, including Law Number 4 of 2009 concerning Mineral and Coal Mining, Law Number 32 of 2009 concerning Environmental Protection and Management, and various derivative regulations. The latter involves investigating legal theories that are pertinent to the defense of residents' rights, including the notion of sustainable development, the right to a healthy environment, and the rights of indigenous peoples to land and natural resources. This research does not involve case studies or interviews, but focuses on a normative study of the applicable legal system. Through an analysis of national and international legal instruments, this research is expected to provide academic contributions in identifying weaknesses in existing regulations and providing recommendations for policy makers in improving legal protection for residents affected by mining projects. Thus, this research can be a basis for strengthening more effective legal protection in maintaining a balance between the exploitation of natural resources and the rights of local communities.

Urinary tract examination with the CT-Scan modality is considered superior to other imaging modalities because it produces better image resolution, clear anatomical details, and is able to accurately detect abnormalities. At the Radiology Installation of Brebes Hospital, the CT-Scan Urography examination is carried out without fasting requirements. Patients are only asked to remove metal objects from the abdominal area and hold urination before the examination begins. This aims to keep the urinary bladder (VU) fully filled so that it facilitates the evaluation of the anatomy of the urinary system, especially in detecting kidney stones which are the main complaints of patients. This study aims to find out in detail the procedure for CT-Scan Urography clinical urography of kidney stones, as well as the reasons why patients are asked to hold urination and are not asked to fast before the procedure is performed. The research method used is a mix method, which is a combination of qualitative and quantitative, with data collection through observation, interviews, and documentation. The research sample consisted of 3 patients who underwent CT-Scan Urography clinical examination of kidney stones at the Radiology Installation of Brebes Hospital. The results of the study showed that the procedure started from the patient's preparation, such as removing metal objects, drinking mineral water, and holding urination so that the VU was fully filled, thus helping the visualization of organs and urinary tract. This examination does not require fasting because the CT-Scan modality is able to provide a clear picture of the anatomy of the urinary tract without interference from the digestive system. These findings confirm that the CT-Scan Urography procedure at Brebes Hospital is simple, effective, practical, and provides optimal diagnostic results for patients.

Infused water is a functional beverage made by soaking slices of fruits, vegetables, and herbs in mineral water to produce a natural flavor and enhance nutritional content.

This article aims to review the latest scientific literature on the potential benefits of infused water on immune function, particularly in the context of regular consumption of natural ingredients such as lemon, ginger, strawberries, and herbs that are rich in vitamin C, antioxidants, and flavonoids. The review was conducted by searching scientific databases such as PubMed, Google Scholar, and ScienceDirect, using inclusion criteria that covered publications from 2020 to 2024. The findings indicate that infused water containing vitamin C, gingerol, and polyphenolic compounds can help improve immune function by reducing oxidative stress, suppressing inflammatory responses, and stimulating immune cell activity such as lymphocytes and macrophages. Furthermore, optimal hydration from infused water supports various physiological processes of the immune system. In conclusion, infused water holds potential as a simple, natural, and cost-effective strategy to support immune health. However, further research is needed to evaluate its efficacy, optimal formulations, and dosage for maximum benefit.

Noodles are commonly made from wheat flour, which is high in carbohydrates but low in fiber, vitamins, and minerals. To enhance their nutritional value, this study used broccoli leaf flour, a vegetable source rich in nutrients and antioxidants. The aim was to evaluate the organoleptic and chemical qualities of dried noodles with added broccoli leaf flour. The study used a completely randomized design with three treatments and two replications. Organoleptic tests (color, aroma, texture, and taste) were conducted by 60 panelists. Chemical analysis measured carbohydrate, protein, fat, calcium, fiber, and moisture content. The results showed that noodles with 10 grams of broccoli leaf flour (treatment B) were most preferred by panelists. This treatment also had improved nutritional content, especially in fiber and calcium, while maintaining acceptable product quality. In conclusion, broccoli leaf flour is a promising ingredient to improve the nutritional value of dried noodles and develop functional food that is well-accepted by consumers.
