Abstract

This study aims to determine the performance of a plastic mulch hole making machine and its electrical power requirements. The study begins by providing speed variations on the engine sprocket, calculating the working capacity of the machine, and analysing the power requirements of the electric motor. The results showed that the engine sprocket could perform an optimal rotation speed for punching holes in plastic mulch. Most holes were created in the treatment with a rotational speed of 70 rpm, 16 holes per 5 m of plastic mulch. Overall, the performance of the plastic mulch punching machine has been able to provide fixes in making holes in mulch plastic. Of the three treatments, the speed variations of the plastic mulch punching machine provided perforations with the criteria of perfect and partial perforation. The highest percentage of ideal perforation was found in the treatment with a rotational speed of 29 rpm, 86%, and the lowest was found in the treatment with a rotational speed of 25 rpm, 9.3%. The coefficient of determination between the rotational speed of the machine and the performance of the machine to punch holes in the plastic mulch can be modelled by a polynomial equation.

Penelitian ini bertujuan untuk mengetahui unjuk kerja mesin pembuat lubang mulsa plastik dan kebutuhan daya listriknya. Penelitian diawali dengan memberikan variasi kecepatan pada engine sprocket, menghitung kapasitas kerja mesin, dan menganalisis kebutuhan daya motor listrik. Hasil penelitian menunjukkan bahwa sproket mesin dapat melakukan kecepatan putaran optimal untuk lubang pelubangan mulsa plastik. Lubang terbanyak tercipta pada perlakuan dengan kecepatan putar 70 rpm, 16 lubang per 5 m mulsa plastik. Hasil kinerja mesin pelubang mulsa plastik telah mampu memberikan perbaikan pada mulsa plastik. Dari ketiga perlakuan variasi kecepatan pada mesin pelubang mulsa plastik memberikan perforasi dengan kriteria perforasi sempurna dan sebagian. Persentase perforasi ideal tertinggi terdapat pada perlakuan dengan kecepatan putar 29 rpm sebesar 86%, dan terendah pada perlakuan dengan kecepatan putar 25 rpm sebesar 9.3%. Koefisien determinasi antara kecepatan putar mesin dan kinerja mesin dalam melubangi plastik mulsa dapat dimodelkan dengan persamaan polinomial.
