Abstract
Terjadinya perubahan iklim yang cukup ekstrem membuat intensitas curah hujan tinggi di seluruh wilayah Indonesia sehingga produksi garam rakyat turun tajam. Data Kementerian Kelautan dan Perikanan mencatat bahwa produksi garam rakyat pada 2016 hanya 188 ribu ton menurun dari tahun sebelumnya 2,9 juta ton. Desa Pengarengan ialah salah satu penyumbang garam tertinggi di Indonesia. Petambak garam di Desa Pengarengan, Kabupaten Sampang umumnya menggunakan teknologi evaporasi bertingkat sehingga butuh waktu 10-12 hari untuk menjadi garam. Oleh karena itu dibuat perancangan sistem model scale alat pencegah bercampurnya air hujan dengan air laut dengan menggunakan sistem kontrol otomatis sensor suhu guna menjaga produksi garam pada musim hujan. Dalam perancangan alat, terdapat beberapa komponen utama, diantaranya arduino, sensor suhu, LCD, motor servo, dan SD card module. Berdasarkan penelitian ini dapat disimpulkan bahwa atap pada model scale alat dibuat miring agar air hujan yang mengenai atap turun ke bawah tanah dan ketahanan atap agar berlangsung lama. Hasil perbandingan garam yang dihasilkan menggunakan sistem model scale alat yang dirancang lebih baik dari metode konvesional. Parameter uji kualitas garam tertera berdasarkan standar SNI 01-3556-2000. Garam yang diproses menggunakan model scale alat diperoleh kadar NaCl 94,086% dan kadar air 4,73%. Sedangkan garam dengan metode konvensional diperoleh kadar NaCl 88,644% dan kadar air 8,909%. Garam yang dihasilkan oleh model scale alat adalah 170g. Sedangkan garam yang dihasilkan tanpa alat hanya diperoleh 150g. Untuk tingkat putih garam, garam dengan penguapan menggunakan alat mempunyai tingkat putih 86% lebih baik daripada garam tanpa menggunakan alat yaitu 80%.

The occurrence of extreme climate change makes the intensity of rainfall high in all regions of Indonesia so that the production of people's salt falls sharply. Data from the Ministry of Maritime Affairs and Fisheries notes that people's salt production in 2016 was only 188 thousand tons, down from the previous year of 2.9 million tons. Pengarengan Village is one of the highest salt contributors in Indonesia. Salt farmers in Pengarengan Village, Sampang Regency generally use multilevel evaporation technology so it takes 10-12 days to become salt. Therefore, the design of a model scale system for preventing the mixing of rain water with sea water is made by using an automatic temperature sensor control system to maintain salt production in the rainy season. In designing the tool, there are several main components, including Arduino, temperature sensor, LCD, servo motor, and SD card module. Based on this study it can be concluded that the roof on the model scale tool is made tilted so that rainwater that falls on the roof goes down underground and the resistance of the roof to last long. The results of the comparison of salts produced using a system scale model of tools designed better than conventional methods. Salt quality test parameters are listed according to SNI 01-3556-2000 standards. Salt processed using a model scale tool obtained 94.086% NaCl levels and 4.73% moisture content. Whereas salt using the conventional method obtained 88.64% NaCl levels and 8.909% water content. The salt produced by the tool scale model is 170g. Whereas salt produced without tools is only 150g. For the level of white salt, salt with evaporation using a tool has a white level of 86% better than salt without using a tool that is 80%.
