Abstract

Indonesia is a country with a tropical climate that has two seasons, namely the dry season and the rainy season. In the dry season, sun drying is the most widely used method for agricultural products. In the rainy season, people who open businesses in the food processing sector have difficulty predicting uncertain weather. The community needs solar thermal energy to dry food ingredients in the form of opak, tubers, fruits, etc. In the rainy season, the value of production has decreased. This study aims to create a drying machine that can help people to dry various types of food and fruit products. The research was carried out in several stages, namely field observation, literature study, design, manufacturing, and performance testing. The study states that: (1) the manufacturing process of electrical machine dryer was done in three stages: the initial stage, advanced stage, and the final stage. (2) the trial of an electrical dryer machine was used to dry opak and banana. Data obtained in the form of opak before drying weighs 3.4 ounces and after drying to 2.2 ounces. Whereas the banana before drying weighs 7.3 ounces and after drying to 4.5 ounces; (3) electrical dryer machine is very helpful in the process of drying food processed products in Subang Regency.

Abstract

Mobil listrik merupakan salah satu teknologi terbaru dalam dunia otomotif yang digerakan dengan energi yang bersumber dari baterai atau tempat penyimpanan energi lainnya. Pembuatan mobil listrik ini adalah salah satu langkah yang diambil untuk membantu mengurangi penggunaan bahan bakar fosil yang menyebabkan terjadinya globalisasi, sehingga akan menghemat energi. Pembuatan mobil listrik sendiri harus memiliki efesiensi tinggi sehingga dapat menghemat penggunaan baterai. Salah satunya adalah dengan cara membuat desain rangka yang kuat dan ringan yang nantinya akan mengurangi beban dan hambatan udara pada saat dijalankan. Hasil penelitian menunjukan proses pembuatan desain rangka mobil listrik ini dimulai dari melakukan studi literatur dan pengumpulan data, dilanjutkan melakukan observasi lapangan, setelah itu membuat desain rangka mobil menggunakan perangkat lunak komputer berupa CAD (Computer Aided Design).

Abstract

Menjaga kualitas dan kesegaran dari buah-buahan dan sayur-sayuran yang membutuhkan waktu perjalanan Panjang adalah suatu keharusan, karena kualitas produk akan berpengaruh pada nilai jual. Sehingga permintaan produk akan semakin meningkat. Dalam menjaga kualitas kesegaran dan kualitas buah – buahan maupun sayur-sayuran dibutuhkan alat yang dapat mengkondisikan udara sehingga suhu dan kelembaban dari komoditi tersebut tetap terjaga.Reefer Coontainer atau kontainer pendingin ini berfungsi untuk mengkondisikan udara. Alat ini biasa digunakan untuk membawa komoditi seperti buah dan sayur untuk di ekspor ke negara lain. Alat ini digunakan karena dibutuhkan waktu yang lama untuk mengirim suatu produk untuk di ekspor ke negara lain. Tetapi ada beberapa kendala yang menyebabkan komoditi mengalami penurunan kualitas yang disebabkan oleh beberapa faktor. Oleh sebab itu perlu dilakukan penelitian untuk mengetahui nilai beban pendinginan total dan kelembaban relatif pada Reefer Container agar temperatur dan kelembaban di dalam kontainer dapat tersirkulasi dengan baik sehingga komoditi yang berada di dalamnya akan terjaga sampai tujuan meskipun memakan waktu yang lama.Beban pendinginan pada suatu mesin pendingin sangat mempunyai pengaruh yang besar terhadap nilai kapasitas pendinginan mesin tersebut. Beban pendinginan juga berpengaruh terhadap nilai COPnya. Semakin besar nilai beban pendinginannya maka semakin kecil COP (Coefficient of Performance) pada mesin pendingin tersebut.
