In line with development, human daily activities are very dependent on electrical technology so that its fulfillment needs to be paid close attention. Given this, the use of mini type power plants or generators is very necessary, especially when the main supply from PLN experiences disruption. Apart from that, currently almost all electrical energy supplies still depend on the use of fossil energy sources which, if used continuously, will cause their availability to decrease and the effects of environmental pollution from the combustion process. To prevent this from happening, efforts are needed to increase the efficiency of using machines that consume fossil fuels and reduce the effects of environmental pollution due to exhaust emissions. Therefore, the aim of this research is to determine the effect of adding an alumina catalyst on exhaust emissions and fuel consumption in engines using experimental methods with load variations of 0 Watt, 250 Watt, 500 Watt and 750 Watt. From the research results, after mixing the catalyst and fuel, it was found that the concentration of CO, CO2, O2 and H2S exhaust gas emissions decreased and fuel consumption could also be reduced from 100% to 66% at a load condition of 750 Watts.

Kepuh biodiesel fuel (sterculia foetida) is an alternative fuel that can be used to replace fossil fuel. Diesel fuel is performed to determine the laminar flame speed of combustion and high flame by adding biodiesel kepuh volume of 10%, 20%, 30%. The purpose of this study was to study the effect of biodiesel and the effect of bunsen burners on the laminar flame speed of combustion and flame height. Bunsen burner is made of copper and stainless steel. Testing of flame characteristics were carried out by heating the mixture of fuel and air at temperature of 200oC. The purpose of heating the air is to prevent cooling when mixed with fuel. The mixture of fuel and air flowed into the mixing chamber and bunsen burner. The mixture of fuel and water flows into the mixing chamber and bunsen burner to form a fire. Flame images were recorded using a high speed fuji film camera with a speed of 480 fps with a resolution of 224x168. The test results were analyzed by measuring the angle and height of the flame using the freeware imageJ program. The results of the B10 (diesel oil without the addition of biodiesel) fuel mixture test using copper bunsen burner produced a maximum laminar flame speed of 23.6264 cm / s at φ = 0.8. The highest value of the B30 fuel mix flame (30% full biodiesel + 70% diesel oil) produces a maximum flame value using a stainless steel bunsen burner with a value of 25,417 mm at φ = 1.2. The results showed that B10 in copper bunsen burner had the highest laminar burn rate. The composition of the fuel and bunsen burner affects the combustion characteristics and flame height.

Research on the use of biodiesel as renewable energy must continue to be carried out as an effort to reduce dependence on fossil energy. This research method was carried out using biodiesel from used cooking oil as an additive to fossil diesel fuel (dexlite). The fuel was tested on a diesel engine as a power generator accompanied by variations in power loading (load). The composition of biodiesel as an additive was (10, 20 and 30)% of fossil diesel fuel, while the power load used during testing was 100 to 700 watts. Testing was carried out to determine the performance and fuel consumption of a diesel engine as a power generator. The test results showed that the highest effective power value was in the D0 composition with a value of 278.18 watts with a power load of 700 watts, while the highest torque value was in the D0 fuel composition of 2.23 Nm at a power load of 700 watts. The lowest fuel consumption was in the D70BIO30 fuel composition of 114.25 seconds at a power load of 100 watts.

Penelitian ini bertujuan untuk menganalisis pengaruh variasi diameter kawat kondensor terhadap hasil distilasi etanol berbasis biomassa. Kondensor dengan diameter 1/4 inci, 3/4 inci, dan 5/16 inci diuji untuk mengevaluasi efisiensi distilasi dalam menghasilkan etanol dengan kemurnian dan volume yang optimal. Proses distilasi dilakukan selama tiga jam dengan pengukuran volume dan kadar etanol setiap jam. Hasil penelitian menunjukkan bahwa pada jam pertama, kondensor 1/4 inci dan 5/16 inci menghasilkan etanol sebanyak 550 ml dengan kadar 90%, sementara kondensor 3/4 inci menghasilkan 390 ml dengan kadar yang sama. Pada jam ketiga, kadar etanol pada kondensor 1/4 inci turun menjadi 0%, sedangkan kondensor 3/4 inci mempertahankan kadar etanol sebesar 65% dengan volume distilat 170 ml. Kondensor 5/16 inci menghasilkan volume tertinggi (390 ml) namun dengan kadar etanol hanya 10%. Hasil ini menunjukkan bahwa diameter kawat kondensor mempengaruhi efisiensi distilasi, di mana kondensor berdiameter 5/16 inci memberikan keseimbangan terbaik antara volume dan kemurnian etanol yang dihasilkan.

The metal heat treatment industry has seen substantial growth, with market projections increasing by USD 15.18 billion from 2022 to 2027, driven by advancements in technology. The iron and steel industry significantly contributes to this growth, accounting for six percent of the market share. In this evolving landscape, the Quenching-Partitioning-Tempering (Q-P-T) technique is emerging as a valuable heat treatment process for enhancing Advanced High-Strength Steels (AHSS). The Q-P-T process, involving Quenching, Partitioning, and Tempering, aims to improve the mechanical properties of medium-carbon steels through controlled thermal modifications. This study explores the effects of varying holding times during the Q-P-T treatment on the mechanical properties and microstructure of medium-carbon steel ST60-2. Steel samples were subjected to holding times of 10, 15, and 20 minutes at a temperature of 920°C, followed by quenching to 350°C and partitioning at the same temperature for 15 minutes, with final tempering at 200°C. The results indicate that longer holding times enhance mechanical properties such as Ultimate Tensile Strength (UTS), Product of Strength and Elongation (PSE), and hardness, with the 20-minute sample (Sample 3) achieving the highest UTS of 74.02 kgf/mm² and elongation of 16.63%. Hardness peaked at 109.33 HRB, and improved toughness was observed due to better phase transformation and carbon partitioning (1.36 Joule/mm²). Microstructural analysis revealed finer and more uniformly distributed cementite particles with extended holding times, contributing to enhanced material performance. The findings underscore the potential of Q-P-T heat treatment in optimizing medium-carbon steels, offering a tailored approach for applications requiring superior mechanical properties.

Biomass gasification is a promising renewable energy technology for the production of synthetic gas (syngas), consisting of hydrogen (H₂), carbon monoxide (CO), and methane (CH₄). This technology's primary challenge is tar formation – a heavy hydrocarbon compound that can block equipment, poison catalysts, and deteriorate syngas quality. Therefore, this study aimed to examine different tar reduction methods to support clean energy production through biomass gasification. To achieve this aim, two main approaches were adopted and the first was in-situ, focusing on modifying gasifier design and adjusting operational parameters. The second was ex-situ, which included catalytic reforming, thermal cracking, and plasma technology. The analysis also assessed different catalysts, such as biochar, and dolomite, as well as nickel- and iron-based materials, comparing their efficiency, sustainability, and economic viability. Several key factors influenced tar formation and reduction, namely feedstock type, operating temperature, air ratio, and reactor configuration. The result showed that combining in-situ and ex-situ technologies had substantial potential to significantly reduce tar, improve syngas quality, and optimize system performance. However, some challenges observed were reduced catalyst efficiency, high energy costs, and the need for more sustainable technologies. To improve the performance of gasification systems, this study provided information on catalyst development, operational parameter optimization, and plasma technology integration. Finally, the analysis provided a scientific basis and strategic recommendations to overcome tar problems and encourage the commercial use of biomass gasification towards a clean energy transition.

In Indonesia, the substantial potential of solar energy remains underutilized, despite the country's advantageous equatorial location, which provides a solar radiation intensity averaging 4.5 kWh/m² per day. The proposed system in this study seeks to maximize solar energy capture by employing a tracking mechanism that aligns the solar cells with the direction of sunlight throughout the day. Additionally, the system is designed with an integrated protection feature to prevent battery overuse, thereby extending the battery's lifespan and ensuring efficient energy storage. The research utilizes an Arduino Uno microcontroller, Light Dependent Resistor (LDR) sensors, and an INA219 sensor module as the primary components for accurate measurement and real-time monitoring. The system's effectiveness is evaluated based on its ability to optimize solar energy reception and maintain the longevity and efficiency of the energy storage system. Experimental results demonstrate that the developed system significantly improves the efficiency of solar energy capture by the solar cells and provides robust protection for the energy storage mechanism. This study contributes to the field of renewable energy by offering a practical solution for enhancing solar energy utilization in regions with high solar irradiance, thus promoting sustainable energy practices and reducing dependence on non-renewable energy sources.
