Abstract

Mesin pencacah memiliki berbagai macam komponen, salah satu komponen utama yang mempengaruhi kinerja mesin pencacah adalah mata pisau. Adapun yang mendasari dilakukannya modifikasi mata pisau mesin pencacah limbah pertanianyaitu, mata pisau yang digunakan pada sebelumnya memiliki kinerja yang kurang optimal sehingga dapat menyebabkan kualitas pemotongan bahan belum optimal dan seragam. Penelitian ini bertujuan untuk mengetahui kinerja mesin pencacah limbah pertanian setelah digunakan mata pisau yang dimodifikasi. Penelitian dilaksanakan mulai dari bulan November hingga Maret 2021. Bertempat di Laboratorium Mekanisasi, Fakultas Pertanian, Universitas Borneo Tarakan. Penelitian ini terdiri beberapa tahapan yaitu identifikasi masalah, modifikasi mata pisau, uji kinerja dan analisis data. Parameter penelitian yang digunakan adalah menghitung kapasitas efektif alat (kg/jam), kecepatan linear (m/s), rendemen (%), suhu mesin penggerak (t), dan kecepatan electromotor (RPM). Dari hasil analisis data berdasarkan parameter yang digunakan diperoleh nilai kapasitas efektif alat 9,14 kg/jam, kecepatan linear 5,28 m/s, rendemen 91,4%, rata – rata suhu 68,3 °C dan rata – rata kecepatan electromotor 234,9 rpm pada mata pisau standar. Kinerja tebaik mesin pencacah limbah pertanian yaitu pada saat menggunakan mata pisau hasil modifikasi dengan  sudut kemiringan mata pisau 10° dengan nilai kapasitas efektif alat 16,35 kg/jam, kecepatan linear 6,20 m/s, rendemen 96,5%, rata – rata suhu 55,5 °C dan rata – rata kecepatan electromotor 275,4 rpm.

Abstract

Building or designing an electric cultivator requires a comprehensive study by paying attention to each main component, namely the chassis. The chassis serves as a place to attach the constituent components and holds the weight of the overall components contained in the tool. A good machine frame will increase the workability of the machine because the components that make up the cultivator are in the right layout. A good chassis design is needed to improve the performance of the electric cultivator. This study aims to design and simulate the strength analysis of the electric cultivator frame. This research consists of several stages, namely literature review, frame design, chassis strength simulation and chassis cultivator capability analysis. From the results of the analysis concluded that technically this tool is classified as safe with a loading condition of 18 kg and a support on its axis. However, it is still recommended that before production, the tool design must be re-optimized. Especially at the joints of the upper and lower frames near the pillow block. This is because this cross section is a critical area because it has a large equivalent stress value, has a small life cycle, and has a low safety factor.

Abstract

Mesin pengering hasil pertanian akan baik jika dirancang berbasiskan logika fuzzy untuk menunjukkan hasil pengembangan maka sistem kontrol fuzzy logic diterapkan pada mesin pengering hasil pertanian tipe batch. Penelitian ini bertujuan menghasilkan prototype alat pengering hasil pertanian menggunakan sistem kontrol fuzzy logic dan mengetahui cara penerapan fuzzy logic pada alat pengering tipe batch. Penelitian ini menerapkan metode hybrid (himpunan fuzzy dan crispntuk mendesain kaidah-kaidah logika fuzzy kemudian mengonversi sinyal kontrol menjadi sinyal yang dapat digunakan untuk menggerakkan aktuator mesin. Hasil penelitian menunjukkan bahwa penerapan sistem kontrol fuzzy logic pada alat pengering biji-bijian tipe batch menunjukkan kinerja lebih baik, tidak terjadi overshoot, dan mampu menghemat penggunaan energi gas LPG selama proses pengeringan. Jumlah daya yang digunakan sistem kontrol selama proses pengujian dilakukan yaitu 304.760 (Watt.jam).

Abstract

The purpose of this study was to determine the quality of coffee bean basket yields with a fuzzy logic controlled incubator. The method in this research is experimentation by packing coffee beans in an incubator using a stirrer and without a stirrer. Fermentation was carried out for 12 hours at 40oC with two repetitions. The amount of fermented coffee was 3.5 kg for each treatment. Stages of hardening: coffee peeling, washing, weighing, and measuring the pH of the air in the stirrer container. After the measurement, the pH of the water was measured, the color test, the water content of the coffee beans, the pH of the coffee powder, and the total acid. The results obtained from this study are in the form of a tool that is tuned using an IoT-based fuzzy logic control system that can perform a temperature control system in the incubator room automatically based on a temperature set point of 40oC, a fan control device that functions to even out the temperature of the incubator room, and the temperature and power parameters used are monitored through the thingspeak application. The rules used to brew coffee beans are quite good based on that there is no overshoot, the steady state error is still in the range of 2-5, the settling time is quite short, stable and the energy used is relatively small during the coffee bean roasting process. Indicators of the quality of coffee beans produced from settlement according to SNI values include the amount of water content of coffee beans using a stirrer, which is 11.04% and without a stirrer, 11.18%, the color of the coffee beans has a chroma/color intensity (L*) value of 33.02 which is close to the biofermentor's L value of 31.71, the pH of coffee grounds steeping is 4.3 and the total acid steeping powder is 0.53%.
