dc.descriptionJus jeruk hasil pemekatan dengan mikrofiltrasi masih mengandung total padatan terlarut yang rendah yaitu 6,8 oBrix. Tingkat kepekatan jus ini masih perlu ditingkatkan untuk mendapatkan konsentrat jus dengan cara mengurangi kandungan air dalam jus. Pada penelitian ini proses pemekatan dilakukan menggunakan Reverse Osmosis Bertekanan Rendah (Low Pressure Reverse Osmosis, LPRO) berbentuk lilitan spiral (spiral wound) berbahan poliamida dan luas permukaan 0,59 m2. Tingkat pemekatan, kualitas jus, dan fluksi diamati pada berbagai variasi laju alir umpan (0,01; 0,015; 0,02; dan 0,03 m/det) dan tekanan trans-membran (TMP) 4, 6, dan 8 Bar. Pada laju alir umpan dan tekanan trans-membran masing-masing 0,03 m/det dan 8 Bar diperoleh tingkat pemekatan tertinggi mencapai 76% menghasilkan konsentrat jus sebesar 11,8 oBrix, dan fluksi 0,73 L m-2 jam-1. Tingkat pemekatan dengan LPRO ini cukup baik sebagai tahap awal proses pemekatan dengan reverse osmosis (RO). Concentration Of Citrus Siam (Citrus Nobilis) Juice By Reverse OsmosisConcentration of citrus juice with microfiltration still contains total soluble solids that is 6.S "Brix. Level concentration of this juice still require to be improved to get juice concentrate by lessening water content in juice. In this research. concentration process used low pressure reverse osmosis (LPRO) in form of circumference of spiral (spiral of wound) poliamide material and surface 0.59 m'. Level of concentration, juice quality, and flux perceived at variation rate of flow (0.01, 0.015, 0.02, and 0.03 m/sec) and pressure of trans-membrane (TMP) 4,6, and 8 Bar. At rate of flow and pressure of trans-membrane{0.03 m/sec and S Bar respectively, it was obtained a high level concentration 76% of equal LO II.S "Brix, and flux 0.73 1 h-1 m-2. This level of concentration with LPRO is adequate as early stage of concentration process of reverse osmosis (RO).en-US
