Rancang Bangun Alat Grading Pemilah Berdasarkan Ukuran Pada Pembuatan Pupuk Granul Organik Mikro Organisme Lokal (MOL)

Abstract

This research was conducted as a continuation of the road map chart. This tool is a grading in the manufacture of local organic microorganism granule fertilizer. The research was conducted with the aim of: (1) Designing a grading machine construction. (2) Developing Standard Operating Procedures for grading operations; and (3) Comparing the grading results. The research was conducted at the Soil Laboratory in July-December 2020 with funding from the Jember State Polytechnic. The research method used was the design method of building tools, preparation of standard operating procedures and comparing the results of grading. The best research results were grade 0.3 to 0.5 cm as much as 87.95 percent. This tool can be recommended as a granular organic fertilizer grading in student practicum, research and community service
