Abstract

Alat otomatisasi buka tutup katup solar dryer berdasarkan nilai kelembaban yang dibaca dari sensor telah berhasil dibuat. Sensor pengukuran dikalibrasi dengan membandingkan nilai pada alat ukur standar (klimaloggpro) dengan nilai toleransi ukur suhu 1°C kelembaban 3%.  Rancangan hardware menggunakan kotak kayu dengan saklar buka tutup, arduino uno sebagai pengatur buka tutup dihubungkan dengan komputer dan sensor suhu dan kelembaban DHT22 sebagai sumber data pengukuran. Pengumpulan data dilakukan dengan tiga sistem solar dryer yaitu sistem tertutup, sistem terbuka dan sistem buka tutup. Sistem buka tutup diatur berdasarkan nilai kelembaban (%) yang dibaca di ruang pengering. Jika membandingkan ketiga sistem pengukuran yaitu sistem terbuka, sistem tertutup dan sistem buka tutup, sistem terbuka lebih baik dibanding sistem buka tutup dan sistem tertutup. Sistem terbuka dapat mengurangi massa air sebanyak 380 gram, sistem tertutup 229 gram, sistem buka tutup 337gram dengan nilai buka tutup 65%-90%.

Abstract

A program of community service has been implemented, with a focus on designing and producing low-cost, easily-assembled solar panels for the Opak-Grembyangan Madurejo Pramabanan village community. Creation of solar panel lighting systems that are practical to use and are capable of producing up to 100 Watts of electricity. The actions taken serve to introduce people to renewable energy sources, educate them about it, and help with solar panel lighting for the master plan area for village tourism development. Village communities may be equipped with the knowledge and skills necessary to create solar panel lights independently and for mass production after receiving continual mentoring and training. Alternative energy management is a more broad goal to be able to lessen reliance on fossil fuels and create a green tourism sector.

Abstract

This study aims to compare dryers for cocoa beans. The comparison carried out is a comparison of tools, moisture content, mass, quality of beans, and the time required by each tool in drying. The drying tools used are traditional solar cabinet dryers and solar tunnel dryers. Conventional drying uses direct sun contact on cocoa beans, and solar tunnel dryer uses two types to dry cocoa beans: hot air absorbed by solar collectors and direct sun. In contrast, solar cabinet dryer uses hot air absorbed by solar collectors and driven by fans in the drying room. The research was carried out from 09.00 until 16.00 in 31/2 hours, so in a day, there are three observation data for each research tool. To the research results, the time required for each tool is different, the solar cabinet dryer tool takes four days, and the solar tunnel dryer traditionally takes three days to dry cocoa beans; drying is done 7 hours a day. The highest ambient temperature is up to 36.3oC, the temperature entering the drying chamber for the solar cabinet dryer is up to 54.2oC, and the solar tunnel dryer is up to 51oC. With a mass of 1.5 kg of material dried to 0.50 kilograms, leaving a moisture content of 12%.
