Performance Test and Economic Analysis of the Fertilizer Applicator Technique (Basal Type) in the Fertilization Process at Division 2 of PT. Pemukasakti Manisindah, Way Kanan Regency

Abstract

Sugarcane is a tropical and subtropical crop that requires optimal maintenance, one of which is through fertilization. Fertilization plays an important role in increasing productivity by adding nutrients, both organically and inorganically. However, its implementation is often hampered by limited time, labor, and land area. Inefficient conventional methods cause low yields and production quality, so a more effective and efficient fertilization approach is needed. The purpose of this Final Project Report is to determine the application of basal type fertilizer applicators in the fertilization process, calculate the unit requirements for these tools according to land conditions, and evaluate the efficiency of their use. In addition, this report also aims to analyze the fixed and variable costs incurred in the operation of basal type fertilizer applicators. The methods used in compiling this final project report are observation, interviews, literature studies and the creation of a final project report. The application of basal type fertilizer applicators at PT Pemukasakti Manisindah is carried out using a spiral pattern with a row of barriers to facilitate tractor maneuvers and save fuel. The tractor starts from the center of the land and moves in a spiral to the right until the entire area is fertilized. Based on calculations, three fertilizer applicators are required to support the fertilization process. The equipment's performance shows a Theoretical Field Capacity (FTC) of 1.24 ha/hour, an Effective Field Capacity (EFC) of 1.02 ha/hour, with a Field Efficiency of 82%. Annual fixed costs consist of depreciation of Rp31,500,000, taxes of Rp14,000,000, and a building or garage of Rp10,500,000, totaling Rp56,000 per year. Furthermore, variable costs per hour include fuel of Rp134,640, lubricants of Rp660,000, operators of Rp16,000, repairs and maintenance of Rp105,000, and other costs of Rp2,666.66.
