Abstract

Hydrogen energy is one of the alternative energies that will help overcome the scarcity of fossil energy. One of the steps to produce hydrogen energy is by the electrolysis method. In this study, the electrolysis process was carried out with a combination of peat water and coconut water. Given that in the South Kalimantan area the existence of peat land is very extensive and there are also many coconut trees. So the main raw materials used can be renewed. In addition, the composition contained in peat water can also help in the electrolysis process which consists of metal minerals such as Na, Mg, Al, Fe, Ca, K, and others. These mineral compounds will also help in accelerating the formation of hydrogen gas. The mineral compounds contained in coconut water and peat indirectly produce electrolyte properties and can be used as catalysts to accelerate the reaction to produce hydrogen gas by the electrolysis method. From the results of the research conducted, as much as 155 ml of hydrogen was produced. Hydrogen gas production, 0.6 A of electric current, and 7.3 Watts of electric power in the 30-minute electrolysis process were found in sample F (1.5 L of pure coconut water). In the electrolysis process, peat water and coconut water, the voltage used during the electrolysis process was 12 V which flowed through the cathode and anode.

Abstract

Catalytic converters function to transform harmful exhaust gases into less hazardous substances through catalytic reactions, primarily oxidation and reduction. This study aims to investigate the potential of corncob waste as an alternative catalytic material in catalytic converters for reducing carbon emissions from diesel engines. The methodology involves synthesizing biochar-based catalysts derived from corncobs via pyrolysis, followed by performance evaluation within a catalytic converter system under varying engine speeds: 700 RPM, 900 RPM, and 1100 RPM. Experimental results demonstrate that catalytic efficiency does not increase monotonically with char content; instead, the 70% char formulation achieved the highest smoke opacity reduction, recording 18.90% at 700 RPM and 14.70% at 900 RPM, outperforming both the 50% and 100% variants at 1100 RPM, where exhaust temperature and flow rate increase substantially, the 100% char catalyst showed comparatively greater stability, achieving a reduction of 5.50%, while the 70% formulation declined to 2.90%. These quantitative outcomes confirm that optimal performance arises from a balanced char loading that maximizes reactive surface area while preserving gas–solid interaction efficiency. Corncob biochar thus represents a viable and sustainable alternative to metal-based catalysts. However, the variability in performance across operating conditions and the need for improved thermal durability underscore the importance of further material optimization for commercial diesel applications.

Abstract

Automatic motorcycles are widely used as the primary means of transportation, making regular maintenance, particularly of the Continuously Variable Transmission (CVT) system, essential to maintain vehicle performance and extend service life. However, public knowledge regarding CVT maintenance remains limited, causing maintenance to be performed only after mechanical problems occur. This community service program aimed to improve the knowledge and basic skills of residents of Desa Pemuda in maintaining CVT components on automatic motorcycles. The program employed a service and mentoring approach consisting of lectures, demonstrations, hands-on training, and interactive discussions. The implementation included three stages: preparation, implementation, and evaluation. The results showed that all participants attended the activity until completion and demonstrated high enthusiasm throughout the program. Participants actively engaged in discussions and practical sessions while expressing positive responses toward the training methods applied. The activity provided participants with additional knowledge and practical experience in performing basic CVT maintenance, enabling them to apply simple maintenance procedures independently. Overall, the community service program successfully enhanced public awareness of the importance of periodic motorcycle maintenance to maintain vehicle performance, reduce the risk of component failure, and encourage sustainable vehicle maintenance practices.
