STUDI EKSPERIMENTAL PENGARUH PENAMBAHAN N-BUTANOL DAN BUTYLATED HYDROXYTOLUENE PADA MESIN DIESEL BERBAHAN BAKAR CRUDE PALM OIL TERHADAP VARIASI PUTARAN MESIN
No full textThe study evaluates the impact of adding n-Butanol and Butylated Hydroxytoluene (BHT) additives on the performance and emissions of a diesel engine fueled with Crude Palm Oil (CPO) and a B40 biodiesel blend. CPO is considered a promising renewable alternative fuel; however, its high viscosity and suboptimal emissions remain key challenges. The experiment was conducted using a single-cylinder diesel engine (Kubota RD 65 DI-NB) connected to a Denyo FA-5 alternator under a constant load of 4000 Watts. The fuel variations tested included preheated CPO (100°C), CPO with n-Butanol, CPO with BHT, B40, B40 with n-Butanol, and B40 with BHT. The tests were carried out across five engine speeds (1250–2250 RPM). Parameters observed included engine power, torque, brake specific fuel consumption (BSFC), thermal efficiency, temperatures of engine components (cylinder block , cylinder head, exhaust pipe, intake pipe, and coolant tank), as well as engine characteristics such as vibration, noise, light intensity, and exhaust emissions (CO, CO₂, HC, and smoke opacity). The results showed that the B40 + n-Butanol blend delivered the best performance, with an average power output of 2.11 kW, torque of 11.30 Nm, and thermal efficiency of 24%. It also produced the lowest levels of CO, HC, and smoke opacity emissions, while the highest CO₂ emissions from this blend indicated the most complete combustion. In contrast, pure CPO exhibited the lowest engine performance and the highest pollutant emissions. The addition of n-Butanol was also found to increase the temperature of engine components due to more intense combustion. In conclusion, the B40 + n-Butanol blend stands out as a more efficient and environmentally friendly fuel option, significantly improving engine performance and reducing emissions, thus demonstrating strong potential as a sustainable alternative to fossil diesel

No full text3D Printing Technology using the Fused Deposition Modeling (FDM) method is an innovative solution for manufacturing lightweight, precise, and economical below-knee prosthetic sockets. This study aims to optimize the printing process parameters, including socket wall thickness, material type (PLA, ABS, PP) and nozzle diameter, against five main parameters, namely printing time, socket mass, specific strength, von Mises stress, and safety factor. The experimental design uses the Taguchi Method with OrthogonalArray L9 (3³), resulting in nine test combinations. Evaluation was performed using Signal to Noise Ratio (S/N) with the criteria “smaller is better” and “large is better” as well as Analysis of Variance (ANOVA) to determine the most influential factors, followed by Desirability Function to determine the optimal combination. The results showed that the most optimal parameters were a thickness of 2 mm, ABS material, and a nozzle diameter of 0.8 mm, with the highest desirability value of 0.753. This combination resulted in efficient printing time, a lightweight socket mass and the highest specific strength value, indicating the best balance between strength and total socket weight. Optimizing 3D printing parameters using the Taguchi method proved effective in improving production efficiency, reducing material consumption and producing lightweight, strong, and comfortable prosthetic sockets for users

KEABSAHAN SURAT WASIAT DALAM PERSPEKTIF HUKUM ADAT MINANGKABAU YANG MENGANUT SISTEM MATRILINEAL
No full textThis research is motivated by the fundamental differences between Indonesian positive law, which grants freedom in making wills under the Civil Code (KUHPerdata), and Minangkabau customary law, which adheres to a matrilineal system, particularly in the management of pusaka tinggi (ancestral property). The main issues examined are the validity of wills from the perspective of Minangkabau’s matrilineal principles and the resolution of inheritance disputes when wills conflict with this system. The objectives of this study are to analyze the legal validity of wills in the context of Minangkabau customary law, explain the role of the mamak (maternal uncle) as a customary authority, and examine the potential conflicts between customary law and national civil law. This study employs a normative juridical method with a descriptive nature, using a conceptual approach, literature review, and interviews with customary leaders. The theoretical framework includes the concepts of customary law, inheritance law, and the principles of customary succession. The findings show that in Minangkabau society, the validity of a will is strongly dependent on compliance with matrilineal principles, particularly regarding pusaka tinggi, which cannot be individually inherited. Conflicts between customary law and civil law often arise when wills disregard these principles, with dispute resolution typically conducted through family deliberation or the intervention of customary leaders. This research concludes that harmonization between customary law and positive law is necessary to ensure legal certainty and justice for customary communities.
