Sebagian peternak, pemberian pakan masih mengandalkan pakan siap saji yang banyak di pasaran. Kondisi ini tentu akan menyulitkan para peternak dari sisi biaya. Oleh karena itu, para peternak harus memanfaatkan sumber daya yang ada dengan bantuan teknologi. Beberapa peternak dijumpai melakukan metode pencampuran konsentrat dan hijauan sebagai pakan, dimana proses tersebut masih dilakukan secara tradisional/manual. Untuk memudahkan peternak, diperlukan suatu mesin yang dapat membantu dalam proses pembuatan pakan. Penelitian ini bertujuan untuk merancang mesin pembuat pakan dan menguji kinerjanya. Penelitian ini dilakukan melalui beberapa tahapan, yaitu desain rancang bangun, perancangan mesin, pengujian, dan pengambilan data. Mesin pembuat pakan ini memiliki dua komponen utama yaitu pencacah dan pengaduk. Bagian pencacah memiliki volume 18,840 cm3 yang dilengkapi dengan dua jenis mata pisau. Mata pisau pertama berjumlah satu buah yang berfungsi sebagai dengan ukuran 36,4 cm x 4,1 cm dan ketebalan 3 mm.

Therefore, it is necessary to have other alternatives as a substitute for fuel. One of the materials that can be used as an energy source is biopellet. This study aims to design a machine used to make biopellets. The biopellet in this study was made from rice husk as raw material. This research was conducted through several stages, namely design and design, manufacture and fabrication, and testing. The biopellet printing machine has a tube-like shape with an outer diameter of 300 mm, whereas on the inside there is a mold with a hole with a diameter of 15 mm. The biopellet printing machine is also equipped with a roller that functions to press the dough to pass through the mold. Tests for making biopellets were carried out three times with different compositions of raw materials. The first test consisted of adhesive and rice husk with a ratio of 0.50:1. The second and third tests have adhesive and rice husk ratios of 0.75:1 and 1:1, respectively. 0.50 liters of water was added to each mixture to form a dough. The test results show that biopellets have different structures and characteristics. The third test had a dense biopellet structure, a smooth and uniform surface, and fewer fractures and cracks. In addition, the productivity is also higher than the first and second tests. This difference is of course many factors that influence, such as emphasis, the main composition of the material, and the size of the main material.","PeriodicalId":172188,"journal":{"name":"Jurnal Teknologi Pertanian Gorontalo (JTPG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129288326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
