Abstract

The availability of energy sources plays a vital role in supporting the efficiency of agricultural mechanisation, especially in the organic fertiliser processing process. This study evaluates and compares fertiliser processing machines' performance using two energy sources: a RON 90 fueled internal combustion engine and a 100 Wp solar power system. Testing was carried out at a fixed load of 3 kg with power and torque parameters observations. The results show that when using a 5.5 HP internal combustion engine, the increase in engine speed is directly proportional to the increase in power but inversely proportional to torque. The highest torque of 14.1 Nm is achieved at 1486 rpm with a power of 2.2 kW, while the highest power of 3.21 kW occurs at 2984 rpm with a torque decreasing to 10.2 Nm. On the other hand, the solar panel-based system showed an increase in power and torque as the intensity of sunlight increased, with the highest performance recorded at 1:00 PM at 91.8 watts and a torque of 0.30 Nm, which then decreased after 3:00 PM, indicating that the engine with a combustion engine has a more consistent performance. In contrast, the solar power system is highly dependent on daily fluctuations in light intensity, so it requires optimal operational time settings.

Abstract

Agriculture is the primary livelihood for most of Indonesia's population, which has vast agricultural land. However, there remains a dependency on chemical fertilizers, which degrade soil quality compared to organic farming that can optimize plant health and productivity. The energy needs in the agricultural sector, including mechanization and fertilizer production, are critical but still heavily reliant on fossil fuels. It is, therefore, essential to reduce this dependency by utilizing environmentally friendly alternative energy sources. This study examines the use of solar energy to power machines in the process of producing organic fertilizer. The tools used in the study include a 100 Wp solar panel, solar energy conversion components, a 12 Volt 33 Ah battery, a ¼ Hp electric motor, a voltage and current meter, a temperature gauge, a sunlight intensity meter, and an organic fertilizer processing machine. The research method analyzes several variables, including sunlight intensity, power, voltage, current, charging time, and battery usage. The study found that the solar panel used was insufficient to power the ¼ HP motor, requiring the addition of three more solar panels and batteries to meet the motor's power requirement of 233 watts. Battery charging tests required 3 hours, and battery usage for machine operation without solar panel installation lasted 1 hour and 40 minutes, while battery usage for machine operation with solar panel installation lasted 6-7 hours. Keywords: Environmentally friendly energy, Fertilizer crushing machine, Organic fertilizer, Solar energy.

Abstract

Manual processing of coconut and the expensive gasoline force farmers to sell copra at low prices. This study explores the potential use of solar energy for operating coconut grating machines. The experiment utilized a 100 Wp solar panel to run a coconut grating machine driven using ¼ HP electric motor. The observation parameters included solar irradiance, power, voltage, current, battery charging duration, and energy efficiency. The results indicate that a 100 Wp solar panel is insufficient to meet the power requirements of the 186 W electric motor. Therefore, adding at least two solar panels and increasing the battery capacity must meet the machine's operational requirements. The battery charging time, until complete, is recorded at 16 h. Without the support of solar panels, the battery can operate the machine for 3 to 4 h. Meanwhile, when the battery is recharged while the machine operates with the solar panel system, the operating duration can reach 6 to 7 h. Therefore, solar energy demonstrates great potential as a renewable energy solution that can be utilized in the agricultural processing process in rural areas in a sustainable and environmentally friendly manner. Testing of the coconut grating machine powered by solar energy, supported by a 12V 100Ah battery and a 1/4 HP motor, showed that it can operate for approximately 3.8 h in a single work cycle. With a grating duration of 2.6 min per coconut, the system can grate up to approximately 87 coconuts per operational cycle.

Abstract

Improving the quality of B-35 biodiesel fuel is crucial, especially in distillation and flash point parameters that affect performance and safety. The objective of this study was to analyze the effect of oxygen ultrafine bubble application on the fuel characteristics of B-35 including cetane number, viscosity, density, flash point, distillation, and cloud point. Tests were conducted according to ASTM standards: D86 (distillation), D93A (flash point), D613 (cetane number), D445 (viscosity), D4052 (density), and D5773 (cloud point). The treatment was performed by injecting oxygen ultrafine bubble at a rate of 1, 3, and 5 l/min into 1.5 liters of fuel for 10–60 minutes. The results showed the highest distillation temperature of 339.7 °C at 1 l/min and 10 minutes, while the lowest temperature of 330.9 °C was achieved at 5 L/min and 60 minutes (control: 341.6 °C). The highest flash point of 72 °C occurred in the low oxygen injection rate and short duration, while the lowest was 64.5 °C in the high rate and long duration. The treatment increased cetane number from 58.6 to 60.8. The decrease in viscosity and density was insignificant but remained within standard limits. The cloud point decreased from 7.1 °C to 5 °C. UFB oxygen addition shows significant potential in improving the quality and combustion efficiency of B-35 fuel
