Abstract

The main objective of this research is to determine the overall performance value of the pneumatic actuator system on a solar-powered pineapple cutting machine. The research methods used are literature study and experimental laboratory. The laboratory experimental method is very suitable to be applied to post-harvest agricultural machines with a small capacity where the research is only focused on the success of the actuator system in carrying out pineapple cutting movements automatically by utilizing pressurized air coming from the compressor. The variation in air pressure for the pneumatic actuator is set at the air pressure, namely 3, 4, and 5 Bar. The actual peeling capacity using air pressure of 3 Bar resulted in 160 pineapple cutting/per hour, 170 fruit/per hour for 4 Bar, 173 bar for 5 bar, and 173 fruit/per hour manually. The efficiency of peeling pineapple manually was 82.8% while using a pneumatic actuator system it was 70.6%. The DC electrical energy storage capacity required for the pneumatic actuator drive system is a battery with a capacity of 80 Ah 12 v which is supplied by electrical energy originating from a 200 Wp solar panel. Solar panels of this size are sufficient to equip a pneumatic actuator system for stripping with capacity of 1 hour/day. The results of this study are expected provide the latest reference for determining the optimal productivity of solar-powered pineapple cutting machines today.

Abstract

Boiling oil palm, especially in Fresh Fruit Bunches (TBS) is one of the most important stages in the palm oil processing process. During the boiling process, it is hoped the temperature and steam pressure, as well as the working time on the sterilizer, are correct so that they do not damage the quality of CPO and that the sterilizer material is also maintained and safe.. Therefore, a thermal analysis was carried out on a horizontal sterilizer using a thermodynamic analysis approach and looking for thermal efficiency at peaks I, II, and III. The research was completed using a mathematical analysis method. Data collection was carried out using literature study techniques and field observations. The results showed that the value of transient conduction on the lorry peak I: 392.476 MJ, peak II: 77.186 MJ, peak III: 28.457 MJ. In oil palm fruit, peak I: 2,164.273 MJ, peak II: 1,407.039 MJ, peak III: 480.314 MJ. at peak I: 606.5398 MJ, peak II: 910.7164 MJ, peak III: 1,063.0479 MJ. The final temperature of the lorry at peak I: 384.5 K, peak II: 400.5 K, peak III: 406.42 K. Meanwhile, the oil palm fruit at peak I: 350.20 K, peak II: 390.115 K, and peak III: 406.268 K. Sterilizer efficiency at peak I: 81.081%, peak II: 80.6716%, at peak III: 80.5332%.
