Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

This research investigates the impact of Continuously Variable Transmission (CVT) roller weight on fuel consumption and engine performance in motorcycles. The study involved experimental testing of motorcycles fitted with rollers of varying weights (9 grams and 12 grams) to evaluate their effects on fuel consumption, and overall engine performance. This study concludes that the choice of CVT roller weight significantly affects both fuel consumption and engine performance, with potential implications for optimizing motorcycle efficiency based on user preferences and riding conditions. This study found that the 9-gram roller produced greater torque and power (7.85 Nm at 3,500 RPM, 8.45 hp at 6,500 RPM) than the 12-gram roller, but its fuel consumption was higher at low RPM (SFC 0.07 kg/hp.h at 1,500 RPM).

Abstract

The efficiency of β-carotene removal is a critical parameter in commercial refining, as it directly influences the overall process effectiveness; therefore, the selection of appropriate bleaching agents is crucial. The limited effectiveness of Bleaching Earth (BE) in refining crude palm oil (CPO) to meet color standards poses a challenge. To improve BE's performance, natural bentonite was modified with nano-SiO₂ through a facile-mixing method. Bentonite was modified with nano-SiO2 in concentrations of 5, 10, and 15% w/v, to assess the effectiveness of this modified bentonite in the CPO bleaching process. Bleaching was conducted at 90°C with a BE concentration of 0.5% w/v for 30 minutes. Characterization confirmed successful integration of modified Bentonite indicated by enhancing surface area. Bentonite modified with 15% nano-SiO2 showed a significant improvement in bleaching performance, reducing β-carotene content to 553.84 ppm compared to 630.36 ppm with unmodified bentonite. The red/yellow color value also decreased to 1.5/15 from the original CPO value of 2.1/21, along with a reduction in FFA value. The results of this study indicate that modifying bentonite with nano silica oxide offers a solution to reduce the amount of bentonite used in the bleaching process.

Abstract

Indonesia aims for 23% renewable energy by 2025 and a 29% reduction in greenhouse gas emissions by 2030 under the Paris Agreement. B35 biodiesel, a blend of 35% palm oil-based biodiesel and 65% diesel, is a key strategic solution for this energy transition. This study, using a mixed method approach with regression analysis, analyzed data from the Ministry of Energy and Mineral Resources and Indonesian palm oil industry reports. It aimed to quantify B35's contribution to the renewable energy mix and project outcomes for a potential B40 policy. An in-depth analysis was conducted to identify the success factors and challenges of biodiesel implementation. Results show B35 biodiesel significantly contributes to Indonesia's renewable energy goals, reaching 38% in 2023 and 38.75% in 2024. Its implementation also led to substantial savings of IDR 120.54 trillion in 2023 and IDR 123 trillion in 2024 by substituting fossil fuel imports. Regression projections suggest that B40 biodiesel could further increase renewable energy contributions to 40.7% with a 15.62 million kL production target in 2025. Additionally, biodiesel usage reduces CO₂ emissions by 8-11% compared to conventional diesel. In conclusion, B35 biodiesel plays a vital role, contributing nearly 40% to Indonesia's national renewable energy. For successful B40 implementation and to optimize biodiesel's role in achieving 2025 targets, a stable Crude Palm Oil (CPO) supply, a USD 4.1 billion infrastructure investment, consistent policy frameworks, feedstock diversification, carbon tax implementation, and strong inter-ministerial collaboration are essential.

Abstract

Palm oil had become one of Indonesia’s leading commodities, contributing significantly to national economic development; however, it faced sustainability challenges, particularly concerning greenhouse gas (GHG) emissions in line with international standards. This study examined the measurement of environmental impact per monetary unit of Crude Palm Oil (CPO) and kernel production in Palm Oil Mill X, by integrating environmental and socio-economic impacts through Eco-efficiency Analysis. The environmental impact assessment was conducted using the Life Cycle Assessment (LCA) method, while the socio-economic impact values were measured using the Economic Input-Output (EIO) method. The data used in this study consisted of primary data and secondary data. Primary data were collected directly from Palm Oil Mill X, including information on production volumes, energy consumption and waste generation. Secondary data were obtained from published literature, government reports and national statistical database to complement and validate the primary data used in the analysis. The study evaluated eleven environmental impact categories, one of which was GWP. The research findings indicated that for a functional unit of 1 ton of CPO, the GWP was measured at 556.31 kg CO₂ eq/ton CPO, with approximately 80% of the GWP originating from CPO processing and wastewater (POME). In terms of socio-economic aspects, the wage multiplier was recorded at 0.930 and the tax contribution at 0.0698, demonstrating the significant contribution of the palm oil industry to labor income. The final economic contribution value (G⁺) was noted to be Rp 23,728,407/ton CPO. The results of the Eco-efficiency Analysis revealed that the GWP per Rupiah was 2.34 × 10⁻⁵ kg CO₂ eq/Rp, indicating opportunities for emission reduction through the use of cleaner energy. This study provided a quantitative overview of the interrelationship between environmental performance and socio-economic benefits, serving as a strategic reference for enhancing the sustainability of the palm oil industry.
