Processing seaweeds using solar and wind energy

Paper Abstract

Seriwe hamlet lies in the South East of Lombok Island, Indonesia where people are growing seaweeds as their main income. The people are living under prolonged poverty with average income of less than US$0.82/day. However, the hamlet is blessed with abundant sunshine and wind all year round with an average of 3396 Wh/m2/day and 5922 Wh/m2/day for solar energy and 4 m/s to 6 m/s for wind energy. The seaweeds are usually dried using direct sunshine under plastic mat on open space along the beach. 

After drying the seaweeds are sold to single buyer at low price. Our idea is to process seaweeds further into several food products of high quality such as local jelly, seaweeds chip, and wanton. The solar energy was used to operate reverse osmosis facilities to produce clean water for processing of raw seaweeds. The wind energy was used to pump brackish water from a well and to make air circulation within the processing building.

Several tests were conducted using solar energy only to produce clean water and it was found that solar power supply within 4 hrs. 6 mins. could produce 2.47 liters/mins, of clean water with TDS of 131 ppm using pressure of 5.1 MPa. Simple economic analysis have shown that by producing process foods, the local cooperative who manage the processing facilities could get benefit  from selling the products. 

Paper Keywords

Corresponding author Biography
Prof. Dr. Kamaruddin was bor on September 10, 1942 and received under graduate and graduate studies in Tokyo Japan from 1962. He received Dr degree in Agricultural Engineering at the University of Tokyo in 1976. His dissertation was dealing with abdsorption cooling machine using thermosipone effect of diluted LiBr-H2O solutions. Upon returning to Indonesia in 1977 he was employed at the Department of Agricultural Engineering, Bogor Agricultural University and at the same time he also worked as Associate Dirctor for the Graduate School of Bogor Agriculural University. In Bogor Agricultural university he continued his research on solar drying, hybrid nocturnal cooling, ammonia based absroption cooling and adsorption cooling machine. He wrote several books on renewable energy applications in Agriculture and Applied Mathematics. He has registered several  property rights on hybrid solar drying with biomass and hybrid  nocturnal cooling. He has attended several international seminar especially the WREC (World Renewabl Energy Congress) since 1990. After retiring from Bagor Agrcultural University in 2006 he was emplyed as Rentor of Darma Persada University, a private university established by former Japanese university alumni. In Darma Persada University he continued his reseach on solar drying and desiccant cooling using solar energy. He also wrote a book entitled Thermal Process using Renewable Energy. After his term of office as Rector was terminated in 2011, he was appointed untilnow as the Director of the Graduate School with program of Study in Renewable Energy.
