      Abstract
      Air laut menjadi bahan baku utama untuk proses penguapan dalam Pembangkit Listrik Tenaga Uap (PLTU). Proses penyaringan air laut di PLTU untuk menghasilkan energi juga menghasilkan limbah, termasuk limbah cangkang kerang. Limbah cangkang kerang di PLTU Banten 3 Lontar dapat dijadikan bahan pengganti untuk berbagai produk dan sisanya dibuang langsung ke Tempat Pemrosesan Akhir (TPA) Jatiwaringin. Tujuan dari penelitian ini adalah (1) mengidentifikasi proses pengelolaan dan pemanfaatan limbah cangkang kerang oleh PLTU Banten 3 Lontar (2) mengestimasi manfaat ekonomi dari pengelolaan limbah cangkang kerang di PLTU Banten 3 Lontar serta (3) menganalisis strategi pengembangan pengelolaan limbah cangkang kerang berkelanjutan di PLTU Banten 3 Lontar. Metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif, analisis kuantitatif dengan pendekatan harga pasar dan PROMETHEE. Hasil penelitian menunjukkan bahwa terdapat pemanfaatan internal maupun eksternal limbah cangkang kerang di PLTU Banten 3 Lontar. Terdapat penghematan biaya karena adanya substitusi tepung cangkang kerang dengan bahan konvensional dalam pembuatan produk sebesar 94,95%. Pengembangan bahan campuran untuk pakan ternak merupakan alternatif strategi terbaik yang menjadi prioritas di PLTU Banten 3 Lontar.
       
      Seawater is the main raw material for the evaporation process in the Steam Power Plant (PLTU). The process of filtering seawater in PLTU to produce energy also produces waste, including clam shell waste. Clam shell waste in PLTU Banten 3 Lontar can be used as a substitute material for various products and the rest is disposed of directly to the Jatiwaringin Final Processing Site (TPA). Therefore, the objectives of this study are (1) to identify the process of management and utilization of clam shell waste by PLTU Banten 3 Lontar (2) to estimate the economic benefits of clam shell waste management in PLTU Banten 3 Lontar (3) to analyze the development strategy of sustainable clam shell waste management in PLTU Banten 3 Lontar. The methods used in this research are descriptive qualitative, quantitative analysis with market price and PROMETHEE approaches. The results showed that there was internal and external utilization of clam shell waste at PLTU Banten 3 Lontar. There are cost savings due to the substitution of clam shell flour with conventional materials by 94.95%. The development of mixed materials for animal feed is the best alternative strategy that is prioritized in PLTU Banten 3 Lontar.
