<![CDATA[This study looks into the thermal risks and ways to deal with them that come with coal self-combustion at the Alam Barajo stockpile, which is run by PT. Kuansing Inti Makmur. Three coal piles: UHS 12F (±2 months), UHS 01A (±1 month), and Medium 11C (±3 months), were monitored to see how the length of time they were stored and how often it rained affected the temperature rise and the subsequent quality loss. The results reveal that the temperature of the pile rises dramatically with extended storage. For example, UHS 12F had a daily rise of 5.04°C, while UHS 01A saw a rise of 1.65°C. Self-combustion in Medium 11C reached a high of 222.1°C, which caused the ash content to rise by 2.62% and the calorific value to drop. Heavy rain made the temperatures drop for a short time, which suggests that evaporative processes caused the cooling. The study shows that present ways of managing stockpiles, especially the FIFO technique, are not being used to their full potential. To reduce the risk of combustion and keep the quality of the coal, engineers advocate making changes like regular temperature monitoring, correct compaction, covering with tarps, and distributing the coal before it catches fire.]]>

<![CDATA[A slope is a sloping part of the ground surface that connects the higher areas with the lower areas. Slope stability relies heavily on rock mass characteristics, including the Rock Mass Rating (RMR) and Geological Strength Index (GSI) classifications, which are used to evaluate rock quality and slope stability. This research was conducted at the mine CV. Putra Idola which is located in Teluk Kabung Tengah Village, Bungus Teluk Kabung District, Padang City and Nagari Siguntur, XI Koto Tarusan District, Pesisir Selatan Regency, West Sumatra Province. The goal is to determine RMR and GSI values and identify potential slope instability. The methods used include geotechnical mapping with a 15.2-meter long scanline technique to identify burly structures as well as laboratory testing to obtain the physical and mechanical properties of rocks. The data obtained were analyzed to calculate the RMR and GSI values of different types of rocks at the research site. The results showed that the GSI values on the three slopes studied ranged from 53 to 75, while the RMR values ranged from 57 to 75. Based on this classification, the Fresh Andesite and Hornfels rocks are included in the "Good" category, while the Weathered Andesite rocks are included in the "Medium" (Fair) category. The results of this study provide important information for the mining industry in efforts to mitigate landslide risk and design safer slope designs. In addition, this study also emphasizes the importance of rock mass classification analysis in the evaluation of slope stability in open pit mining activities.]]>

<![CDATA[Air pollution in urban areas is a multidimensional threat with systemic impacts on the environment and public health. Carbon monoxide (CO), as a toxic gaseous pollutant from the incomplete combustion of fossil fuels, is the focus of this study which evaluates the spatial-temporal distribution of CO concentrations in public spaces of Padang City during 2020-2024. Using a Systematic Literature Review (SLR) approach and longitudinal environmental data from four strategic points, a significant decrease in CO levels was found from 14,596 µg/m³ (2020) to 286 µg/m³ (2024). Peak concentrations occurred in the dry season, reinforcing the influence of meteorological variables. These results emphasize the importance of real-time digital monitoring systems, multi-sectoral emission policy reformulation, and integration of green open spaces in urban planning. In the future, monitoring should be expanded to other pollutants, congestion locations, and linked to public health early warning systems to support urban sustainability and resilience.]]>

<![CDATA[This paper examines the interplay between ethical norms and anti‐ethical norms in shaping investment decisions within Indonesia’s renewable energy sector. Drawing on Mertonian ethical norms as a theoretical backbone and contrasting them with non‐market strategy perspectives, the study reviews how business ethics intersect with renewable energy policy, investment, and sustainable development in Indonesia. Using recent data from national energy statistics and empirical studies on renewable energy and ESG disclosure , the paper develops a research framework. By combining institutional theory and stakeholder theory, this study uses a theory-driven conceptual qualitative approach to provide a normative-analytical framework that clarifies how ethical standards and non-market tactics influence Indonesia's investment in renewable energy. The framework suggests that a balanced approach—integrating both ethical imperatives and pragmatic market strategies—can drive progress toward national targets such as the Golden Indonesia 2045 vision and the Paris Agreement’s zero‐carbon goals.]]>

<![CDATA[The screwing process is one of the important stages in the assembly of industrial products that requires high precision and time efficiency. This study implements Finite State Automata using Nondeterministic Finite Automata with the Mealy Machine model. The implementation of Finite State Automata on a 6-axis robot in the screwing process allows for better control, because each step in the process can be analyzed and programmed clearly. The system is controlled by a programmable logic controller that integrates a 6-axis robot, human machine interface, screwdriver, sensors, and pneumatic actuators. The screwing process is carried out using an automatic screwdriver, with the robot's movement following a logical sequence based on the Mealy Machine model state diagram. Each state represents the robot's operational steps, from taking tools, screws, to the screwing process. The study focuses on designing a system to move the robot according to the state diagram that activates the output based on the state transition to the input. The results show that the implementation of Finite State Automata is able to complete the screwing process consistently and repeatedly. This system also considers safe points to avoid collisions, thus supporting safety in the screwing process. The application of Finite State Automata on 6-axis robots is expected to provide convenience for users in understanding robot control in the screwing process and can be implemented according to industrial needs.]]>

<![CDATA[This study aims to design a warehouse management information system by implementing the 5S method to address the stock checking and item arrangement disorganization at PT Total Teknologi Rekacipta. Currently, the company conducts stock recording manually, resulting in poorly arranged items, ungrouped spare parts, lengthy stock-checking processes, and frequent data duplication. The 5S method (Seiri, Seiton, Seiso, Seiketsu, and Shitsuke) is applied to organize the warehouse area, supported by developing a web-based inventory information system using the Waterfall methodology. The system is developed using PHP and MySQL, featuring data input, storage location tracking, and photo documentation. Black box testing results show that all functional system requirements are met. This system enhances stock management efficiency and accelerates company decision-making processes. The implementation reduced stock checking time from 1–2 days to less than 1 minute and eliminated data duplication. While 5S and web-based inventory are well-known approaches, this study contributes a practical implementation model by combining warehouse organization through 5S as a preparatory step before digitalization. This stepwise approach can serve as a reference for small and medium enterprises seeking to improve their physical warehouse management and digital stock control practices.]]>

<![CDATA[This study presents a thermo-structural finite element analysis of a single-cylinder diesel piston using ANSYS, comparing three aluminum alloys: Al2618-T61, Al4032-T6, and Al6061-T6. A coupled simulation approach was applied, where steady-state thermal results were imported into static structural analysis. Realistic boundary conditions, including applied combustion pressure, symmetry constraints, and cylindrical pin supports, were implemented based on Yanmar TF55 engine geometry. Results indicate that Al6061-T6 experienced the highest deformation and stress, nearing its yield limit at elevated temperatures. In contrast, Al2618-T61 and Al4032-T6 maintained structural integrity, with lower stress and elastic deformation within safe limits. Al4032 demonstrated superior dimensional stability, while Al2618 exhibited better strength under thermal load. These findings validate the importance of coupled thermal-structural analysis and material selection in piston design. The proposed framework offers reliable guidance for developing more durable, thermally resilient pistons for modern diesel engines.]]>
