This study was conducted to evaluate the level of conformity between actual mining activities in March 2025 and the monthly sequence design plan at PT Tama Raya's P3000BK14 pit. The evaluation focused on geometric deviations, volume achievement, and changes in field conditions that influenced these discrepancies. The data used included the sequence design, actual topography from the TLS (Low-Scale Land Survey), and weekly production realizations. The results showed significant discrepancies between the planned and actual operations in weeks 2 and 4, primarily in the form of overcuts, undercuts, non-designed contour changes, thinning of the coal seam, and hydrological obstacles such as ponding and unstable drainage. The R2 sequence redesign in week 4 proved to improve the overburden excavation flow but did not fully restore coal access due to persistent geological and water conditions. These findings emphasize the need for more rapid topographic updates, more intensive water handling, and interdepartmental coordination to ensure better synchronization of plans and operations.

Rapid and precise handling in determining fault locations is essential to accelerate post-fault recovery and minimize economic losses caused by power outages. Several methods employed to identify fault locations include Single Ended and Double Ended analysis. This paper discusses the Selective Mode Double Ended Fault Locator Method, an enhancement of the IEEE C37.114 Double Ended method. This approach involves selecting maximum fault data values for Near Side (NS) and Far Side (FS) calculations, taking into account the differential or angle difference of the sequence between the two sides. The Double Ended calculation results from the total sample values are used to determine the mode, which serves as the final output of this Fault Locator method. This method is designed to identify faults and their locations with high accuracy and speed. Based on the research findings, the Selective Mode Double Ended (SMDE) method provides more accurate fault locator analysis compared to the Single Ended and Double Ended methods. The accuracy achieved with the Single Ended method is 90.9%, with the Double Ended method reaching 94.9%, and with the Selective Mode Double Ended (SMDE) method achieving 99.9%.

The rapid growth of financial technology (fintech) Peer-to-Peer Lending (P2PL) in Indonesia has created both opportunities and challenges, particularly regarding debt collection practices by third parties (debt collectors). Such practices often result in violations of consumer rights, including intimidation, harassment, and breaches of privacy. To address these issues, the Financial Services Authority of Indonesia (OJK) issued Regulation No. 22 of 2023 on Consumer and Public Protection in the Financial Services Sector, which establishes legal standards for protecting fintech P2PL consumers. This study aims to analyze the regulation of debt collection by third parties under OJK Regulation No. 22/2023, assess the forms of legal protection for consumers, and identify the obligations of fintech P2PL providers in managing collection practices. The research applies a normative juridical method with statutory and conceptual approaches. The findings indicate that OJK Regulation No. 22/2023 provides consumer protection through preventive mechanisms (mandatory transparency, prohibition of intimidation, and regulation of third-party involvement) and repressive mechanisms (complaint handling and administrative sanctions). However, challenges remain in implementation, such as low consumer literacy, outsourced collection practices, and weak on-site supervision. Therefore, stronger regulation, tighter controls by providers, and collaboration among regulators, law enforcement, and fintech associations are required to ensure optimal consumer protection.

Along with the development of the times and increasingly competitive market demands, there is an urgent need to develop post-harvest handling strategies based on technological innovation, strengthening farmer capacity, and developing supporting infrastructure in Makale District. This strategy not only aims to reduce the level of yield loss, but also increase product added value, expand market access, and encourage agricultural-based regional economic growth. This study uses the SWOT Analysis Method used to evaluate strengths, weaknesses, opportunities and threats in the implementation of rice post-harvest handling strategies. The results of this analysis can be used to formulate recommendations for more effective and sustainable strategies for farmers and other stakeholders. The results of the study by carrying out a SWOT analysis include strengths including long experience, farmer group socialization, quality awareness, weaknesses including dominant age old, limited capital, traditional methods, high yield loss, opportunities including government programs, local rice demand, the role of extension workers, the availability of appropriate technology and Threats including extreme weather, competition with modern areas, limited infrastructure, low farmer regeneration. This study emphasizes the importance of transforming harvest-post-harvest practices from traditional to semi-modern based on farmer groups. A combination of training, provision of tools and ongoing support is essential to reduce yield losses, improve grain quality and maintain agricultural sustainability in Tana Toraja.

The study titled “Judges’ Speech Acts in Handling Criminal Cases at the Gorontalo District Court” aims to describe the forms, functions, and meanings of speech acts used by judges in leading court sessions. The introduction emphasizes the importance of language in judicial processes to establish effective, fair, and authoritative communication among judges, defendants, prosecutors, and legal counsels. This study employs a descriptive qualitative method with a pragmatic approach. Data were collected through direct observation, documentation, and transcription of court proceedings. The analysis is based on Austin and Searle’s speech act theory, which includes locutionary, illocutionary, and perlocutionary acts. The results show that judges use various types of speech acts, such as directive, declarative, representative, and expressive acts. Illocutionary acts, particularly commands, questions, and assertions, are the most dominant. Their functions are not only to direct the course of the trial but also to maintain order, emphasize legal aspects, and clarify understanding among the parties involved. In conclusion, judges’ speech acts serve as strategic communicative tools with pragmatic power that influence the course of the trial and determine the effectiveness and fairness of the judicial process.

This study examines the implementation of Fardhu kifayah counseling in Telagah Village, Sei Bingai District, Langkat Regency, focusing on the social and cultural problems and challenges faced by the local community. Telagah Village is known for its rich history, strong traditions, and local wisdom that shape its social life. However, in the practice of handling the deceased, several issues remain, including limited community knowledge, lack of regeneration among younger members, inadequate facilities, and the absence of a designated team responsible for the Fardhu kifayah process. These limitations often lead to dependence on a few individuals who possess the necessary skills, creating sustainability concerns in the long run. Furthermore, cultural aspects such as conservative norms, gender role divisions, and deeply rooted customs influence how the community perceives and accepts Fardhu kifayah counseling. The study highlights that successful implementation requires not only technical guidance but also sensitivity to local values and traditions. Strengthening community participation and fostering collaboration between religious leaders and local authorities are essential to ensure the sustainability and effectiveness of Fardhu kifayah education in Telagah Village.

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.

Errors in the pre-analytical phase are a dominant factor causing inaccurate laboratory test results, including blood serum cholesterol analysis. Pre-examination specimen handling is crucial to ensure the quality of measurement results. This study aimed to compare serum cholesterol levels in blood frozen before centrifugation with those immediately centrifuged. The research method was analytical using a cross-sectional design. A total of 35 respondents were involved, consisting of laboratory staff, emergency room staff, pharmacists, and administration at Sinar Kasih GKST Tentena Hospital. Blood samples were obtained via venipuncture after participants had fasted for 10–12 hours. Each sample was then separated into two groups: those immediately centrifuged and those frozen 20–30 minutes before centrifugation. Data collection was carried out by examining serum cholesterol levels using an Erba Mannheim Chem-7 photometer. The results showed that the average cholesterol level in frozen samples was higher (161.4 mg/dL) compared to samples immediately centrifuged (140.45 mg/dL). The Mann-Whitney statistical test yielded a p-value of 0.006 (p<0.05), indicating a significant difference between the two treatments. This confirms that pre-analytical handling of blood specimens significantly impacts the validity of cholesterol test results. Therefore, careful attention to the pre-analytical stage is essential to ensure the accuracy of laboratory results.

One part of the large intestine can be affected by an anal fistula or rectovaginal fistula due to infection of the anal glands. In patients who have undergone colonostomy, radiological examinations such as lopography are necessary to detect abnormalities, especially in the anal region. Pediatric lopography with clinical rectovaginal fistula post colonostomy at the Radiology Department of Dr. Sardjito General Hospital involves inserting contrast media into the proximal section through the proximal stoma with an anteroposterior projection and into the distal section through the anal opening with a lateral projection. The study aimed to determine the contrast enema examination procedure in pediatric patients with clinical rectovaginal fistula post-colonostomy, including examination techniques, patient preparation, equipment and materials used, as well as handling problems such as blockages in the distal intestine. Methods: The study was conducted in May–June 2025 using a qualitative descriptive method through observation, interviews, and documentation, involving three radiographers and one radiologist. Data analysis was performed through data collection, data reduction, data presentation, discussion, and conclusion drawing. Results: The results showed that lopography examinations used water-soluble iodine contrast media mixed with NaCl at a ratio of 1:3, which was inserted through the proximal stoma and anus. Preparation included fasting from breast milk, confirming patient identity, informedconsent, and preparation of equipment such as an X-ray machine with fluoroscopy, catheters, syringes, and Computed Radiography.

Welding work on ships carries high risks of health disturbances due to exposure to heat, smoke, chemicals, and poor ergonomic work positions. This study aims to identify potential occupational health hazards among welders working on the MV KAREEM ship at PT. Samudra Marine Indonesia in 2025. The study uses a descriptive observational design with total sampling technique, involving 30 welders. Data were collected through direct observation using observation sheets and documentation in accordance with the welding SOP. The results of the study revealed five categories of health hazards. Physical hazards included excessive heat, noise, and poor lighting. Chemical hazards included welding fumes, metal dust, and toxic gases. Biological hazards arose from exposure to microorganisms in the work environment. Ergonomic hazards were related to awkward posture, prolonged static positions, and manual handling loads. Psychosocial hazards included long working hours, high workload, and conflicts among workers. The findings emphasize that welders are prone to health disturbances due to various risk factors. Preventive measures, including improving the work environment, implementing stricter safety standards, and providing occupational health education, are essential to reduce these risks.

The increase in traffic volume in urban areas often triggers various problems, especially at Road intersection points that have a high level of interaction between vehicles. One of the locations that experience these problems is the intersection with the island of traffic without signal on Jl. Tebu-Jl. Tabrani Ahmad, City Of Pontianak. This study aims to analyze the performance of the intersection in the existing condition and project its performance in the next five years (2030), as well as formulate alternative treatment that can improve the smoothness of traffic. The analysis method refers to Indonesian road capacity guidelines (PKJI) 2023 and modeling using software PTV VISSIM. The data collected include intersection geometry, traffic volume, and vehicle speed. Traffic volumes were obtained through CCTV recordings for three consecutive days, then processed and presented in the form of tables and graphs for easy interpretation. The results of the existing condition analysis showed that the degree of saturation (DS) reached 0.407 with an average delay of 9.539 seconds (Level of Service/LOS B) based on PKJI, while VISSIM simulation resulted in a delay of 12.54 seconds (LOS B). The five-year projection (2030) shows an increase in DS to 0.878 with a delay of 15.177 seconds (LOS C) from PKJI, and 23.35 seconds (LOS C) from VISSIM, which indicates a decrease in Junction performance as traffic grows. Two handling alternatives were analyzed, namely the construction of roundabouts and the implementation of traffic flow management. VISSIM simulation shows that the roundabout can reduce the delay to 14.31 seconds with a queue length of 20.34 m (LOS B), while the flow management produces a delay of 11.81 seconds with a queue of 13.14 m (LOS B). This result confirms that both alternatives are able to improve the performance of the intersection compared to the projected condition without handling, so that it can be a technical recommendation for urban traffic planning in Pontianak.

This study is motivated by the downstream Teh Walini industry’s reliance on third-party logistics (3PL) services for product distribution, which restricts the company’s control over several key aspects, including logistics costs, delivery speed, routing efficiency, and product handling quality. The primary objective of this research is to analyze and compare distribution costs between outsourced logistics and self-managed delivery, and to evaluate the potential cost efficiency of an independently operated shipping system. A descriptive comparative quantitative method is employed, incorporating movement generation analysis, distribution spread mapping, and Vehicle Operating Cost (VOC) calculations to estimate the cost implications of self-shipping. Data were obtained through company documentation and analyzed using multiple linear regression involving six major distribution points. The results reveal that shipment volume significantly influences movement generation, with Waingapu, Makassar, and Padang identified as the dominant distribution destinations. The cost comparison analysis demonstrates that self-managed delivery is more cost-effective than third-party logistics services, making it a more viable long-term option. These findings suggest that transitioning to a self-delivery system could improve cost control and logistical efficiency for the company. However, this strategy should be implemented gradually, supported by regular updates on operational cost data and proactive management of external factors that could impact distribution performance. The study concludes by recommending broader coverage and the inclusion of additional relevant variables in future research to further validate and enhance decision-making related to distribution strategies. A well-informed shift toward internal logistics could ultimately contribute to greater competitiveness and sustainability in the company’s distribution operations

UMKM Tahu XYZ, a small-scale tofu producer, is currently facing significant challenges in maintaining consistent product quality, primarily due to a high defect rate. Common issues identified include crumbled tofu shapes, overly soft textures, and inconsistent taste, which negatively impact customer satisfaction and business sustainability. This study aims to investigate the root causes of these quality issues and propose practical solutions using the Lean Six Sigma methodology. The research employs a descriptive quantitative approach through the DMAIC framework—Define, Measure, Analyze, Improve, and Control—to ensure systematic problem-solving. Data were collected over a six-month period through direct observation, structured interviews, and review of production records. The analysis identified four dominant types of waste within the production process: unnecessary transportation, product defects, excessive movement, and over-processing. The root causes of these inefficiencies are linked to poor handling of raw materials, variability in soybean quality, and an ineffective production layout that hampers workflow and consistency. To address these problems, the study proposes several targeted interventions, including the redesign of the production layout to optimize flow, the implementation of the 5S (Sort, Set in order, Shine, Standardize, Sustain) workplace organization method, the development of standardized operating procedures (SOPs), and the adoption of improved soybean boiling technology. The implementation of these improvements is projected to significantly reduce product defects, enhance process efficiency, and ultimately increase customer satisfaction. Furthermore, these actions are expected to improve the overall competitiveness of UMKM Tahu XYZ within the highly demanding food industry sector. This research provides actionable insights for other micro, small, and medium enterprises (MSMEs) seeking to apply structured quality control methods to strengthen operational performance and long-term business resilience.

Community diagnosis is a strategic step that aims to identify fundamental problems in the community, determine problem priorities, and formulate appropriate solutions to overcome them. One of the identified health issues is a significant increase in cases of mumps (epidemic parotitis), an acute infectious disease caused by the mumps virus, a member of the Rubulavirus genus. This increase in cases was recorded in the Puskesmas work area from the beginning of the year to November 2024. This phenomenon raises concerns regarding the potential for widespread health problems at the community level. Therefore, this intervention activity was carried out with the hope of reducing the incidence of mumps in the Puskesmas work area.The methodology applied in this activity includes data collection through mini surveys, analysis of health determinants using the Blum Paradigm, determination of problem priorities through the Delphi method, and identification of root causes using a fishbone diagram. Based on the results of this analysis, the interventions implemented include counseling on mumps and preventive measures, as well as demonstrations of proper hand washing. The results of the intervention showed a significant increase in knowledge, where all participants (n=40, 100%) obtained a post-test score of ≥ 7, indicating a good understanding of the material presented. In the demonstration session, a number of participants were also able to demonstrate the steps for washing hands according to the correct procedure. From the results of the analysis, it was found that the increase in mumps cases in this area was closely related to community lifestyle factors. Therefore, this intervention is expected to not only increase community knowledge about mumps, but also encourage the implementation of clean and healthy living behaviors, especially in the practice of washing hands, as a preventive measure to reduce the number of transmissions and accelerate case handling.

Civil servants play a crucial role in governance and development to achieve the national goals as stipulated in the Preamble to the 1945 Constitution of the Republic of Indonesia. Civil servants (PNS) are the primary foundation for the implementation of the Indonesian government system, as they implement public policy and provide public services. Their integrity, competence, and legal status significantly determine the quality of government bureaucracy. This study aims to determine the role of the Regional Civil Service Agency (BKD) in handling cases involving civil servants using fake diplomas during recruitment or promotion. The approach used is normative juridical, reviewing existing regulations, such as Law Number 5 of 2014 concerning the State Civil Apparatus, Government Regulations, and other technical regulations. Data were also obtained through interviews with BKD officials and analysis of relevant case documentation. The results of the study indicate that in practice, there is still a discrepancy between established legal procedures and their implementation in the field. Several cases indicate that administrative sanctions or termination of civil servants found to have used fake diplomas have not been fully based on proper verification and sanction mechanisms. This raises doubts about the validity of decisions and has the potential to undermine public trust in government institutions. This study emphasizes the importance of enforcing administrative discipline and improving internal oversight systems, as well as the need for stricter and more coordinated regulations between central and regional agencies to ensure that every administrative action has a valid legal basis. Implementing the principles of accountability and transparency in personnel management must be a priority to create a clean and professional bureaucracy.

This study examines the legal liability of a Limited Liability Company (LLC) before and after bankruptcy, with a focus on the roles of the board of directors, board of commissioners, and the curator appointed by the Commercial Court. Prior to bankruptcy, the liability for the company's obligations rests primarily with the board of directors and the board of commissioners, especially when debts arising from binding agreements remain unpaid. In situations where the company is unable to fulfill its payment obligations, and such inability is confirmed by a final court ruling, responsibility for managing and settling the company’s debts and assets is transferred to a court-appointed curator. The research analyzes the legal framework governing the curator’s authority, which operates under the supervision of a supervisory judge from the Commercial Court. The curator acts as the sole party responsible for handling the bankrupt entity’s obligations to creditors, ensuring compliance with applicable bankruptcy laws. This study uses a normative juridical approach, relying on legislation, case law, and legal doctrine to examine the extent of responsibility at each stage of the bankruptcy process. Special attention is given to the legal considerations of the Central Jakarta Commercial Court in Decisions Number 34/Pdt.Sus-Pailit/2024/PN Niaga Jkt.Pst and Number 38/Pdt.Sus-Pailit/2024/PN Niaga Jkt.Pst. Both rulings are found to be appropriate, as they meet the legal requirements for declaring an LLC bankrupt based on verified facts and circumstances. The findings underscore the importance of distinguishing between pre-bankruptcy liabilities—borne by company management—and post-bankruptcy responsibilities, which are entirely managed by the appointed curator. This clear allocation of responsibility ensures creditor protection, maintains judicial oversight, and upholds the principles of fairness and legal certainty in bankruptcy proceedings

One form of crime that is highly relevant in the context of today's society is the crime of embezzlement in office. This embezzlement can be defined as a dishonest act committed by one or more individuals by hiding goods or property belonging to another person without the owner's knowledge. This action aims to transfer ownership of the goods, which can be categorized as theft, taking possession of goods, or using the goods for unauthorized personal gain. In many cases, embezzlement in office often involves individuals who have access or authority over company assets, making it easier for them to commit misuse. This study applies a normative juridical research method to analyze existing problems in the context of criminal law. This method allows researchers to explore and understand applicable legal norms and how they are applied in real cases. The results of the study show that the Judge's Ratio Decidendi in imposing sanctions on cases of embezzlement in office, as stated in Decision Number 542/Pid.B/2023/PN Cbi and Decision Number 355/Pid.B/2024/PN Cbi, is based on a number of in-depth legal considerations. In this case, the judge first explained the elements contained in Article 374 of the Criminal Code (KUHP) charged by the public prosecutor. The defendant was found guilty of committing embezzlement in office by embezzling company funds for personal gain. Therefore, the defendant was sentenced commensurate with his actions, which violated Article 374 of the Criminal Code. Criminal liability for the perpetrator of the crime of embezzlement in office has been legally and convincingly proven, with all elements of the charge having been fulfilled. This indicates that the perpetrator can be subject to sanctions in accordance with applicable legal provisions, thus providing a deterrent effect and upholding justice in the criminal law system. This research is expected to contribute to the development of understanding regarding embezzlement in office and its legal implications in Indonesia, as well as encourage more effective law enforcement in handling similar cases in the future.

Currently, the world is facing Global Warning Phenomena, El Nino and La Nina, each of these natural phenomena makes above-average rainfall at a time and place and an area, especially impacting large cities that are passed through by water due to high rainfall. With inadequate city channels to accommodate rainwater flow, it results in, among other things, high floods, landslides due to the soil no longer being able to accommodate high rainfall, high Rob floods due to seawater overflowing into coastal areas of the city. Based on the disaster data due to high rainfall, Research, Handling and Mitigation Planning is needed with the aim of obtaining data for drainage design. The study is the observation of rainfall for 2 years, 5 years, 10 years, and 20 years, so that by calculating the intensity of rain using the Gumbel and Pearson III Log distribution methods, accurate data is obtained to determine the drainage dimensions that must be made in a city and the dimensions of retaining walls along the coast to overcome storm disasters in coastal areas or big cities.

Waste management problems in Kudus City show high complexity, marked by an increase in the volume of daily waste generation that is not balanced by an adequate handling system. This study aims to optimize the waste management system in an integrated manner with an industrial engineering approach, especially through the application of the Lean Waste Management concept, redesigning facilities and logistics, and strengthening community participation based on Human-Centered Design (HCD). A qualitative method with a case study approach was used, with data triangulation techniques in the form of in-depth interviews, direct observation, and document analysis. The results of the study showed that 75% of households did not sort their waste, only 2 out of 6 TPSTs were active, and the TPA capacity had exceeded its limit since 2022. The efficiency of the transportation system is also low due to suboptimal routes and frequencies. This study offers solutions based on technology integration, facility redesign, logistics optimization, and community empowerment. With a systemic approach based on industrial engineering, an efficient and sustainable waste management model can be applied, not only in Kudus, but also in other areas with similar challenges.
