Abstract

Diesel engined vehicles are one of the biggest causes of air pollution. Exhaust emissions will continue to increase along with the growth in the number of motorized vehicles, especially for commercial vehicles. The main purpose of this study is to determine the quality of fuel can affect the level of smoke density in diesel engines. This research was conducted by testing sampling on a motor vehicle that is commonly used by the public, namely the Mitsubishi L300 in 2007 production using a Smoke Tester. The test mechanism utilizes different fuel variables, namely: Bio Solar with Additive Substances, Solar Dexlite and Pertamina Dex. From the test results, the highest smoke density value was achieved on Bio Solar fuel with additives at 4200 rpm engine speed with a value of 34.1%.

Abstract

In the automotive world, rapid advancements in motorized vehicle technology necessitate consumers to be selective in vehicle choice. This study examines the performance of motorcycles using modified racing rollers versus standard factory rollers. Focusing on a 150cc matic motorcycle, we analyzed power and torque outputs using rollers of different masses (11g, 16g, and standard 15.5g). Field studies and literature reviews were conducted, employing tools like dynotests to measure performance at RPM ranges from 4,700 to 9,500. Results indicate that the 16g roller achieved the highest torque of 12.45 N/m at 6,800 RPM, while the 11g roller attained 12.09 N/m at 67,300 RPM. The standard 15.5g roller reached 12.07 N/m at 76,400 RPM. This research highlights the impact of roller mass on motorcycle performance, providing valuable insights for enhancing vehicle efficiency and consumer choice. Highlight: 16g roller achieves highest torque of 12.45 N/m at 6,800 RPM. 11g roller reaches torque of 12.09 N/m at 67,300 RPM. Standard 15.5g roller attains 12.07 N/m at 76,400 RPM.

Abstract

People's consumption of household electronic devices is increasing, leading to higher energy demand in Indonesia, with washing machines being a significant contributor. This study explores repurposing used washing machine dynamos into electricity generators for windmills. Researchers used an LG washing machine dynamo and N52 neo super magnets, testing pulley diameters of 12 cm, 15 cm, 18 cm, and 20 cm. Results showed that larger pulleys increased generator output, with a 20 cm pulley producing 26 volts, 1.3 amperes, and 2525 rpm. However, the efficiency was low at 8.69%, indicating a need for further optimization. This approach has potential for sustainable energy solutions and reducing electronic waste. Highlight: Repurpose Dynamos: Converts washing machines to windmill generators, reducing electronic waste. Efficiency Challenge: Larger pulleys improve output but efficiency is only 8.69%. Sustainable Impact: Offers potential for sustainable energy and lower household consumption. Keyword: household electronics, energy consumption, washing machine dynamo, windmill generator, sustainable energy
