Abstract

Peanuts are the second largest legume crop in Indonesia, both cultivated on farms and wild. In 2019-2023, Indonesia experienced a decline in peanut production due to the declining in harvesting area. In addition, this is also due to the poor quality of seeds in the cultivation process. This study aims to observe the performance of the Multi Seed Smart Dryer (MSSD) machine for peanut seeding. This research was conducted by observing changes in moisture content, drying rate, drying temperature, and peanut germination test results using the Multi Seed Smart Dryer machine. The results showed that the left side of all shelves experienced an increase in temperature because it was close to the heat source and the level of temperature uniformity was still said to be uniform because it did not exceed the uniformity limit. The peak drying rate occurred at the 12th hour and decreased further. Based on the results of the germination test, the dried beans have a germination rate of 83%. This is in accordance with the passing standard of seed quality according to the Ministry of Agriculture of the Republic of Indonesia and International Seed Testing Association. Keywords: Drying, Multi Seed Smart Dryer, Peanut, Temperature.

Abstract

A rainfall simulator is laboratory equipment used to simulate rainfall and replicate the characteristics of natural rain with parameters such as rain intensity, raindrop diameter, rain kinetic energy, rain uniformity coefficient (CU), and rain distribution uniformity (DU). Therefore, this study aims to design a rainfall simulator for rain simulation with good performance. Portable rainfall simulator performance tests include functional tests and performance tests. Functional tests to ensure that the portable rainfall simulator is easy to assemble, lightweight, and functions well. Meanwhile, performance tests are carried out by analyzing rain intensity, raindrop diameter, kinetic energy, uniformity coefficient (CU), and rain distribution uniformity (DU). The results of the study indicate that the rainfall simulator functions well, is easy to assemble, and is lightweight so that it can be applied to various field conditions. Meanwhile, the rainfall simulator performance test shows good performance, with a significant linear relationship existing between pump pressure, rain intensity, raindrop diameter, and kinetic energy. Likewise, the results of the rainfall simulator performance evaluation produce good output with an average of CU and DU greater than 80%. Thus, the portable rainfall simulator functions well and can be used for rainfall simulation.
