Abstract

Jahe merupakan salah satu komoditas pertanian yang memiliki prospek yang baik untuk dikembangkan di Indonesia. Teknik penanganan produk pertanian merupakan hal yang sangat penting untuk dilakukan, hal ini karena sifat dari produk pertanian yang memiliki tingkat kerusakan tinggi. Pembuatan simplisia jahe melalui metode pengeringan adalah salah satu cara untuk meningkatkan kualitas produk dengan kandungan kadar air yang lebih rendah. Penelitian ini dilakukan dengan menggunakan electrical oven dengan suhu pengeringan 45oC, 55oC, dan 65oC. Penelitian ini dilakukan untuk mengkaji model kinetik yang cocok untuk karakteristik pengeringan jahe. Hasil penelitian menunjukkan bahwa semakin tinggi suhu pengeringan maka semakin cepat mencapai kadar air setimbang. Kondisi terbaik untuk pengeringan jahe adalah pada suhu pengeringan 65oC. Terdapat tiga model kinetik yang digunakan untuk menginvestigasi perilaku MR untuk pengeringan jahe yaitu Newton, Handerson dan Pabis, serta Page. Model page menghasilkan nilai R2 sebesar 0,9986 pada suhu pengeringan 65oC, dimana nilainya mendekati 1. Hal ini menunjukkan bahwa model page ditemukan paling cocok untuk menggambarkan kinetika pengeringan jahe dalam tiga tingkatan suhu pengering dengan menggunakan electrical oven dibandingkan model lainnya yang diuji.

Abstract

Mining commodities such as coal, gold, copper, and other mining products are closely related to the use of conveyors. In the material handling process, metal shards follow into the bulk material. This incident can cause damage to the crusher teeth. Therefore, this study developed a conveyor with a metal impurity sorting system. To detect, the sensor used is an inductive proximity sensor. When Mining material moves from the head pulley to the tail pulley, the inductive proximity sensor detects metal shards. The proximity sensor detects metal shards to be input, and then the Arduino Uno orders the servo motor to move the sorting lever. The independent variables used are mining materials and metal shards. The mining materials are used in the form of coal, sand, and rock. At the same time, the metal shards are iron (Fe), Copper (Cu), and Aluminum (Al). The dependent variable used is the response effectiveness of the metal sorter. Based on the study's results, the conclusion is that the proximity sensor can work well. The inductive proximity sensor can detect metal shards with a success rate of 92.59%. When the sensor detects metal impurities, instructions will be given to the servo motor and actuate the sorting lever. The success rate of the sorting lever that pushes and separates metal impurities from the mining material is 88.89%.
