Abstract

Jagung merupakan tanaman pangan yang penting di Indonesia, karena selain digunakan sebagai bahan makanan pokok, tanaman jagung juga bisa digunakan sebagai pakan ternak, diambil minyaknya, dibuat tepung (maizena), serta bahan baku industri. Namun, jagung yang dihasilkan petani seringkali cepat dan mudah terkontaminasi jamur, sehingga harus dilakukan pengeringan di bawah sinar matahari. Akan tetapi, sekitar 75% produksi jagung di Indonesia dihasilkan pada saat musim hujan, sehingga para petani sangat kesulitan untuk melakukan pengeringan jagung dan membutuhkan alat pengeringan jagung mekanis dengan sistem kontrol. Penelitian ini bertujuan untuk (1) Merancang prototipe pengeringan otomatis dengan pengendalian suhu berbasis arduino uno, (2) Mendapatkan hubungan pengaruh parameter suhu dan aliran udara terhadap pengeringan jagung dan (3) Memperoleh efektivitas pengeringan jagung otomatis. Hasil penelitian menunjukkan bahwa dari 1 variabel kontrol dan 4 variabel terikat menunjukkan bahwa variabel P5 (variabel terikat dengan pengeringan mekanis sistem kontrol dengan Arduino on, kipas atas bawah on, kipas kanan kiri on, termokopel on, heater on) merupakan skenario terbaik dari perbandingkan dengan variabel pengeringan mekanis sistem kontrol lainnya dengan tingkat waktu dan proses pengeringan biji jagung yang efektif dengan mendapatkan rata-rata suhu pada perbandingan variabel kontrol sebesar 45.4 °C, RH 29.3 % dengan durasi pengeringan terbaik yaitu 18 menit. Skenario P4 dinilai lebih efektif dibanding skenario P1 (variabel dengan pengeringan manual atau dijemur), skenario P2 (variabel terikat pengeringan mekanis sistem kontrol dengan Arduino on, kipas kanan kiri off, kipas atas bawah off, termokopel on, heater on), skenario P3 (variabel terikat pengeringan mekanis sistem kontrol dengan arduino on, termokopel on, kipas atas bawah on, kipas kanan kiri off, heater on) dan skenario P4 (variabel terikat pengeringan mekanis sistem kontrol dengan arduino on, kipas atas bawah off, kipas kanan kiri on, termokopel on, heater on). Dengan proses pengeringan biji jagung dengan skenario P5 tersebut, akan membantu para petani dalam pengeringan biji jagung untuk menurunkan kadar air yang sesuai keinginan yaitu 12-14%.

Abstract

The development of sugar palm plants in Indonesia is very prospective. Can increase farmers' income from sugar palm farming, as well as preserving natural resources and the environment. The application of post-harvest technology for palm fruit that is not yet optimal causes the production of palm fruit to be very low. So researchers are interested in designing a tool for processing kolang kaling. The general aim of this research is to design a fruit processing machine for kolang kaling fruit. The specific aim of this research is to analyze, design and build flatteners for kolang kaling machines. This research method uses the experimental method with a combination of qualitative and quantitative approaches, while the data analysis technique used uses quantitative techniques. The measurement results show that the length of time for peeling, flattening and separating palm seeds required by the designed machine is faster than manually. The time required by the machine designed to peel 10 kg of palm fruit is an average of 38.6 seconds, while the manual requires 470 seconds. After stripping, the flattening process is carried out. The results obtained in one rotation of the flattening shaft are that it can flatten 180 palm fronds in a time of 2 seconds. In conclusion, the designed palm fruit flattening machine can flatten palm fruit without taking a long time. The time required to peel palm fruit using a designed machine is more effective than the manual method.

Abstract

Corn is a superior commodity owned by Indonesia. Apart from being a staple food, corn kernels are also used as chicken feed by grinding them using a grinding machine. But the processing of corn as animal feed is still relatively expensive. Breeders usually process corn to the mill because they don't have a grinding machine. Meanwhile, buying a grinding machine is not cheap. So to increase productivity and effectiveness in the livestock sector, it is necessary to develop technology or tools in this field. One of the technological developments that can be applied to this sector is the use of grinding machines for corn kernels. We made this machine with the aim of increasing efficiency and saving on animal feed costs. The design of this machine is carried out through the process of designing, selecting and calculating components, the stages of making and assembling the whole, as well as testing the machine. The machine was designed using Autodesk Inventor software to help design the whole. The control and electrical systems are designed using the Simurelay application. This machine has specifications of 250 watt motor power, 712 RPM rotation and 3.29 Nm torque which is capable of grinding dry corn kernels up to 30 kg/hour.

Abstract

Maggot black solder fly (maggot black solder fly) is the larvae of the black solder fly, many are found in various tropical countries, especially in Indonesia. On average, people in Indonesia dispose of food waste about 300 Kg every year, the amount of food waste is a problem that must be addressed. resolved Utilizing organic waste as a feed medium for black solder fly maggots is one way of processing and utilizing organic waste. The main driver of this machine is an electric motor. Power is transmitted through the pulley and the V- belt to the gearbox and then shaft to generate rotation. Here the electric motor and belt-pulley transmission have an important role. Namely, the electric motor as the main driver and the belt-pulley act as the power transmission system,which is where the selection of a V-bel for transmisi power has the advantage of producing greater power at a relative low voltage. So on this occasion the author designed a V-belt transmission, the pulley-shaft that is right for the black army fly maggot dryer.

Abstract

Dodol is a traditional Indonesian food made from glutinous rice, palm sugar, coconut milk, salt, and water. All the ingredients are mixed and stirred until reaching a certain thickness, usually requiring 4-8 hours of cooking time. During the mixing process, dodol must be continuously stirred to prevent it from burning or forming a crust. This design aims to create a machine that can assist in the dodol production process, particularly in the stirring process, to make it more effective and efficient. The method involves designing a dodol stirrer machine frame. The design of this dodol stirrer machine frame uses Autodesk Inventor Professional 2023, with a material of 4x4 cm angle iron with a thickness of 3 mm, capable of supporting a load of 10 kg. The stress analysis results for this dodol stirrer frame are sufficiently safe, with a value of 29.5 MPa, compared to the maximum limit of 147.3 MPa. The results from the frame manufacturing process, using welding with an SMAW machine and E6013 electrodes, show that the frame can support each component and does not experience excessive vibration when the dodol stirrer machine is operational.
