Abstract

Pencampuran pakan ternak merupakan tahap yang sangat penting dalam memenuhi kebutuhan gizi ternak. Saat ini, pencampuran pakan ternak masih umumnya dilakukan secara manual dengan menggunakan sekop dan cangkul yang dikerjakan oleh tenaga manusia. Penelitian ini bertujuan untuk merancang sebuah alat pencampur pakan ternak dan melakukan uji teknis guna meningkatkan efisiensi proses pencampuran pakan ternak. Pendekatan penelitian yang digunakan adalah pengembangan alat. Alat pencampur pakan ternak yang dikembangkan memiliki kapasitas hopper sebesar 28 kg. Hasil penelitian menunjukkan bahwa alat ini mampu mencampur pakan hingga 120 kg dalam satu jam, dengan waktu pencampuran 10 kg bahan selama 5 menit, menghasilkan campuran yang merata dan homogen, serta tanpa ditemukan gumpalan. Alat pencampur pakan ternak ini dapat mencampur dengan kecepatan rotasi rata-rata sebesar 38,7 RPM. Selain itu, kebisingan yang dihasilkan oleh alat ini rata-rata sekitar 77,37 dB, yang tetap berada di bawah batas kebisingan yang diperbolehkan. Durasi pencampuran juga memengaruhi suhu alat dan bahan yang dicampur.

Abstract

Innovation in agricultural mechanization is crucial for the sustainable development of agricultural machinery in Indonesia. This study aims to design and develop a cutting force measurement device for agricultural products. The device consists of a mechanical system utilizing a linear actuator (5.88 mm/s) as a blade pusher and a control system employing a load cell as a force sensor. Testing was conducted using three blade types with cutting angles of 10°, 15°, and 20° on taro, chayote, and papaya. Measurement data were displayed as graphs on an LCD and stored as XLS files on an SD card. The tested materials had moisture content ranging from 85% to 95%. Results showed that taro required the highest cutting force (74.3 N), followed by chayote (39.77 N) and papaya (31.1 N), corresponding to their hardness and moisture content. In contrast, the highest cutting speed was observed in chayote (6.1 mm/s), followed by papaya (5.8 mm/s) and taro (3.5 mm/s) using a 20° blade. These findings confirm that harder materials with lower moisture content require greater cutting force than softer materials with higher moisture content. Keywords: Controller, Cutting force, Load cell, Mechanization, Small-scale.

Abstract

Straw is an organic material that has the potential to be used as a basic material for making compost. Rice straw rich in cellulose and lignin, requires a long composting process. The use of IoT as a compost monitoring system is needed to predict the level of compost maturity to meet standards. The aim of this study is to design a composter that is integrated with the development of a monitoring system to obtain data on temperature, humidity, and pH distribution in real time as reference to determine the maturity of straw compost. The monitoring system used based on an ESP32 which was connected to DHT22 sensors, DS18B20, soil moisture sensor V1.2, and soil pH sensor. Data collected from these sensors was transmitted and visualized through the Antares website. The temperature of the composter reached its peak on the 7th day with a value of 56.7°C. The temperature of the compost material reached its highest peak on the 7th day with a value of 42.75°C. The pH value is in the range of 5.5 – 7.4 from the beginning to the end of composting. C/N ratio of compost is 18.13 and is in accordance with SNI 19-7030-2004. Monitoring was conducted for 35 days, in accordance with the estimated compost maturity. Keywords: Humidity, pH, Sensors, Straw, Temperature.

Abstract

Telah dilakukan penelitian mengenai analisis tekno-ekonomi mesin pencacah hijauan (chopper) tipe vertikal di kelompok tani harapan sejahtera aie pacah dengan perlakuan ragam bahan uji. Penelitian ini bertujuan untuk melakukan analisis teknis dan analisis ekonomi mesin pencacah (chopper) tipe vertikal dengan perlakuan ragam bahan uji yaitu rumput gajah, rumput raja, dan tebon jagung. Pengamatan analisis teknis yang dilakukan adalah kapasitas kerja mesin, perubahan frekuensi putaran poros motor penggerak dan poros pencacah, konsumsi bahan bakar, daya mesin, torsi motor, tingkat kebisingan mesin, kecepatan angin keluaran, dan hasil cacahan terbaik mesin. Pengamatan analisis ekonomi yang dilakukan adalah biaya pokok dan titik impas mesin. Pengamatan mesin pencacah menggunakan 3 ragam bahan uji, didapatkan hasil bahwa ragam bahan uji berbeda nyata terhadap kapasitas kerja, frekuensi putaran, debit bahan bakar, daya motor, torsi motor, tingkat kebisingan, dan titik impas mesin. Didapatkan nilai kapasitas kerja mesin menggunakan bahan rumput gajah, rumput raja, dan tebon jagung secara berurutan yaitu 1302 kg/jam dengan rendemen 86,9 %; 1380,8 kg/jam dengan rendemen 92,1 %; dan 1412 kg/jam dengan rendemen 94,1 %. Nilai biaya pokok mesin untuk rumput gajah, rumput raja, dan tebon jagung secara berurutan adalah Rp 45,05/kg; Rp 43,3/kg; dan Rp 42,58/kg.
