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. Keywords: manufacturing, electrical dryer machine, opak and banana.

Kabuapten Subang merupakan sentra penghasil buah nanas terbesar di Indonesia. 500 keluarga menggantungkan penghasilannya dari bertani nanas, dengan kepemilikan lahan perkebunan rata-rata 0,4 Ha, namun petani hanya terfokus kepada produksi nenas belum menyentuh kepada pengolahan hasil.sehingga yingkat kesejahteraan petani masih belum optimal. Pengabdian masyarakat ini bertujuan menambah pengetahuan petani melalui penyuluhan dan pembinaan mengenai tata cara pegolahan produk nanas seupaya memiliki nilai tambah. Pelaksanaan pengabdian kepada masyarakat dilaksanakan di  Kecamatan Compreng, Kabupaten Subang selama bulan Juli sampai Oktober 2019 dengan menggunakan metode ceramah, focus group discussion, pelatihan dan pendampingan serta monev. Hasil dari pengabdian masyarakat ini yaitu masyarakat dapat membuat olahan dari nanas sebagai upaya dalam meningkatkan nilai tambah dari produk nanas itu sendiri. Kesimpulan dari pengabdian masyarakat ini yaitu pelaksanan kegiatan pengabdian masyarakat mampu membantu masyarakat untuk meningkatkan kesejahteraan melalui peningkatan nilai produk dan nilai jual dari produk serta masyarakat mampu mengembangkan manajemen kelembagaan.

The process of draining oil is one of the processes that can affect the oil content of the frying or chips. The oil that is left in a lot of fried food or chips when stored for a long time will cause a rancid smell. Meanwhile, if consumed directly, it will affect the health of consumers because of high cholesterol levels. Most people do not know the consequences that occur if they consume excess oil. People who already know cannot do anything because the oil draining machines on the market are still quite expensive and their working capacity is limited. In the previous research, a draining machine with a tube system with a diameter of 40 cm and a height of 22.2 cm was made with an rpm of 517. Within 5 minutes this system reduce oil content from 27% to 24,65% . The data shown in strightline gaphic trend that mean the reduction oil conten is not optimal yet . For this reason, this research will be redesigned by extending the spinner axis and adding the bearings to 2 units, it is hoped that this addition will stabilize the spinner rotation, the rotation can be increased and the ability to reduce oil content increases. extending the drain axis and increasing the position of the bearing to 2, the draining machine has been able to function properly until 967 rpm rotation, from the test results for draining the cassava chip oil, within 5 minutes, the slicer with a rotation of 598 rpm can reduce 2.29%, 727 rpm 2.93%, and 967 rpm 4.27% rotation.

The fish feed spreader machine is a feeding tool that is made to facilitate fish breeders in feeding fish. The fish feed spreader is specially programmed to provide fish feed according to the schedule and the desired dose. The purpose of making this tool is to design a fish feed spreader machine based on the logic controller programmale, and to test the performance of the designed fish feed spreader machine. The results showed that the average feed expenditure was 2.66 kg for a duration of 40 seconds. Then for the farthest throw of feed is 7.5 meters, while for throw of feed that is evenly distributed it has a distance of 5 meters with a spread width of 5.85 meters, and the angle of spread of feed is 90º.
