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

Pengelasan gesek sangat baik dalam metode penyambungan khususnya pada logam poros. Namun pengelasan gesek ini masih jarang dikenal pada bengkel-bengkel pabrikasi. Bengkel pabrikasi tentunya memiliki mesin bubut yang dapat dimanfaatkan dalam proses pengelasan gesek dengan mengaplikasikan alat bantu pada mesin bubut tersebut. Penelitian ini bertujuan melakukan rancang bangun alat bantu tekan berbasis hidrolik pada proses pengelasan gesek, sehingga didapatkan cara kerja dari alat dan hasil pengujian alat. Alat bantu tekan gesek berbasis hidrolik ini diaplikasikan pada mesin bubut dalam proses pengelasan gesek. Pengujian alat pada proses pengelasan gesek dilakukan pada material poros 1 inchi dengan kecepatan putar ditetapkan 1600 rpm dan memvariasikan tekanan gesek yaitu 5 kg/cm2, 10 kg/cm2, dan 15 kg/cm2. Berdasarkan hasil pengujian alat yang telah dirancang dalam proses pengelasan gesek pada material poros 1 inchi diperoleh tekanan gesek 5 kg/cm2 tersambung dengan waktu 317 detik, tekanan gesek 10 kg/cm2 tersambung dengan waktu 47 detik, dan tekanan gesek 15 kg/cm2 tersambung dengan waktu 39 detik. Besarnya tekanan gesek mempengaruhi kecepatan penyambungan material pada proses pengelasan gesek. Studi lebih lanjut tentang parameter-parameter yang optimal untuk melakukan pengujian mekanik dalam pengaplikasian alat bantu tekan berbasis hidrolik pada proses pengelasan gesek, seperti hasil rekomendasi dari variasi tekanan gesek dan waktu pengelasan gesek. Dengan adanya alat bantu tekan gesek berbasis hidrolik pada proses pengelasan gesek menjadi suatu alternatif di dunia usaha / dunia industri khususnya pada bengkel pabrikasi yang memiliki mesin bubut.

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.
