Abstract

In increasing the productivity of cattle using the cage method, adequate feed availability is needed. In the process of providing feed, farmers in Mandala Village still use the traditional method of chopping feed which requires a lot of energy and time. The purpose of this study was to make a chopping machine for animal feed and to find out the results of the machine chopping. The methods used are observation, literature review, and experimental methods. The grass chopper machine as a result of the research has a chopping chamber size of 36 x 36 x 49 cm, blade 27 x 5 x 1 cm, with a gasoline motor drive of 5.5 HP, transmission pulley and V-belt type A-45. The results obtained were 5 kg of grass using 02.07 minutes, 19.25 kg of trees and banana leaves in 02.48 minutes, while for midrib and palm leaves of 5.75 kg it took 02.25 minutes with each size of the chopped results between 3 -6 cm at engine speed between 2000-2260 rpm.

Abstract

In increasing cattle productivity by using the cage method, adequate feed availability is needed. Farmers in Mandala Village still use the traditional method of chopping feed during the process of providing feed, which requires a lot of energy and time. The purpose of this research is to make a chopping machine for animal feed and to find out the results of the machine chopping. The method used is observation, literature review, experimental method, and design method. The grass chopper machine as a result of the research has a chopping chamber size of 360 x 360 x 490 mm, blade 270 x 50 x 10 mm, with a gasoline motor drive of 5,5 HP, transmission pulley, and V-belt type A-45. The chopping results obtained were 5,75 kg of palm fronds and leaves, 19,25 kg of trees and banana leaves, and 5 kg of grass in the chopping time of 02.00 minutes each at an average engine speed of 2100 rpm with the size of the chopped results between 3-6 cm

Abstract

This study examines the performance of solar photovoltaic (PV) systems with off-grid and on-grid configurations as practical learning media at Politeknik Kotabaru. The testing was conducted on AC loads with parameters including solar radiation intensity, voltage, current, and the power stored in the battery. Monocrystalline and polycrystalline solar panels were used to compare energy conversion efficiency. The results show that monocrystalline panels perform better than polycrystalline panels, with average differences in power and efficiency of 1,30 W and 0,50% in the off-grid system, and 1,11 W and 0,44% in the on-grid system. Solar radiation intensity significantly affects output power and conversion efficiency, with the highest power of 49,28 W obtained at the maximum radiation intensity of 1015 W/m². This study confirms that the PV system trainer can serve as an effective learning medium to enhance students’ competence in understanding the differences between off-grid and on-grid systems.

Abstract

The utilization of biomass as a renewable energy source represents a strategic alternative to reduce dependence on fossil fuels while promoting the sustainable use of organic waste. This study aims to evaluate the effect of varying ratios of bamboo charcoal and coconut shell charcoal, with coconut husk charcoal and binder composition kept constant, on the combustion characteristics of biomass briquettes, including ignition time, burning duration, and maximum combustion temperature. The research was conducted experimentally through biomass pyrolysis at a temperature of 300 °C for 10 hours, followed by material mixing, briquette molding, and combustion testing. The results indicate that variations in raw material composition significantly influence briquette combustion behavior. Briquettes with higher bamboo charcoal content exhibit faster ignition, whereas those dominated by coconut shell charcoal produce longer burning duration and higher combustion temperatures. The observed combustion behavior is qualitatively discussed based on differences in biomass characteristics as reported in the literature. These findings demonstrate that blending biomass with different combustion properties can achieve more balanced briquette performance.
