ABSTRAKDalam kegiatan penelitian ini telah dilakukan studi konservasi energi di satu industri tekstil proses pertenunan, pencelupan dan penyempurnaan. Studi ini bertujuan untuk mempelajari pola konsumsi energi, menganalisa potensi penghematan penggunaan energi dan mengevaluasi peningkatan efisiensi energi melalui implementasi program konservasi energi. Metode penelitian terdiri dari: observasi, pengumpulan data dan pengukuran, identifikasi potensi penghematan energi, implementasi program konservasi dan evaluasi peningkatan efisiensi energi. Hasil identifikasi selama satu tahun mulai dari bulan Juni 2014 sampai Mei 2015 menunjukkan konsumsi energi spesifik (KES) dalam proses produksi adalah sebesar 51,02 MJ/yard. Program konservasi energi yang telah diimplementasikan adalah: heat recovery dan reuse air kondensat dari proses pencelupan (rasio penghematan 7,02%), penyempurnaan insulasi perpipaan sistem uap (rasio penghematan 0,81%), pengurangan kebocoran uap pada sistem distribusi uap panas (rasio penghematan 0,04%), dan pemeriksaan dan perbaikan kebocoran udara pada perpipaan udara bertekanan (rasio penghematan 0,07%). Evaluasi terhadap implementasi program konservasi energi di lokasi studi selama periode Januari -Mei 2016 menunjukkan bahwa konsumsi energi spesifik dan biaya energi dapat dikurangi masing-masing sebesar 7,36% dan 6,63%. ABSTRACTIn this research, energy conservation study in textile weaving, dyeing and finishing processing industry was carried out. The aims are to determine energy consumption pattern, analyze potential of energy consumption saving and evaluate energy efficiency improvement through implementation of energy conservation program. Research method consists of: observation, data collection and measurement, conservation program implementation and evaluation of energy efficiency improvement. Results of identification along one year start from June 2014 until May 2015 shows that specific energy consumption of production process were 5.02 MJ/yard. Several implemented energy conservation program were : water condensate recovery and reuse from dyeing process (saving ratio of 7.02%), improvement of heat insulation at steam system piping (saving ratio of 0.81%), fixing steam leakage of steam distribution system (saving ratio of 0.04 %), and checking and fixing of air leakage at compressed air piping (saving ratio of 0.07%). Evaluation of energy conservation program implementation in studied location during January to May 2016 shows that specific energy consumption and energy cost reduced up to 7.36% and 6.63%, respectively.
