This work covers waste energy utilization of the combined power cycle by using it in the candle raw material (paraffin) melting process and an economic study for this process. After a partial utilization of the burned fuel energy in a real bottoming steam power generation, the exhaust gas contains 0.033 of the initially burned energy. This tail energy with about 128 ºC is partly driven in the heat exchanger of the paraffin melting system. Ansys-Fluent Software was used to study the paraffin wax melting process by using a layered system that utilizes an increased interface area between the heat transfer fluid (HTF) and the phase change material (PCM) to improve the paraffin melting process. The results indicate that using 47.35 kg/s, which is 5% of the entire exhaust gas (881.33 kg/s) from the exit of the combined power cycle, would be enough for producing 1100 tons per month, which corresponds to the production quantity by real candle's factories. Also, 63% of the LPG cost will be saved, and the payback period of the melting system is 2.4 years. Moreover, as the exhaust gas temperature increases, the consumed power and the payback period will decrease.

Abstrak: Pengelolaan sampah di Kota Pematangsiantar masih bertumpu pada pendekatan akhir (kumpul-angkut-buang), dengan tingkat pelayanan yang rendah, sehingga untuk meningkatkan pelayanan sampah, perlu dilakukan pemilahan di tempat penampungan sementara (TPS). Penelitian ini bertujuan untuk mengkaji sistem pengelolaan sampah dengan melakukan pemilihan di TPS dapat meningkatkan pelayanan aset persampahan sampai tahun  2015 secara teknis operasional dan dari aspek keuangan. Analisa teknis operasional aset pengelolaan sampah mulai dari pewadahan, pengumpulan dan pengangkutan sedangkan analisa keuangan dan analisa kelayakan menggunakan Net Present Value, Internal Rate of Return, Benefit/Cost Ratio, dan Payback Period. Dari hasil analisa tersebut diperoleh suatu sistem pengelolaan sampah dengan pemilihan di TPS berdasarkan zona pelayanan dengan skala prioritas secara bertahap daritahun 2013-2017, dapat meningkatkan cakupan pelayanan sampah eksisting rata-rata 6,69 %, cakupan pelayanan TPS eksisting rata-rata 8,29 %, dan cakupan pelayanan truk pengangkut sampah eksisting rata-rata 12,03 %. Investasinya layak, diperoleh Net Cashflow pada tahun 2020 sebesar Rp 1.720.242.284,-, NPV suku bunga 15 % bernilai positif, IRR > MARR 15 %,  B/C Ratio > 1, dan PP 4,7 tahun, lebih pendek dari periode investasi 10 tahun. Dari Metode penelitian ini maka pengumpulan data, observasi lapangan dan pengukuran contoh timbulan sampah dengan sampel 4 TPS perumahan yang terlayani pengangkutan.

Mineral timah mengandung mineral ikutan berharga apabila dilakukan pengolahan lebih lanjut. Menurut Peraturan Menteri Nomor 25 tahun 2018 mineral ikutan harus dilakukan pengolahan dan pemurnian di dalam negeri. Tujuan penelitian ini adalah untuk menganalisis potensi, arah peningkatan, dan kelayakan inivestasi pada peningkatan nilai tambah mineral ikutan timah. Analisis investasi mineral ikutan timah dilakukan dengan menggunakan metode evaluasi ekonomi berupa NPV yang menunjukkan kelayakan bila bernilai positif, IRR dengan menggunakan suku bunga acuan 10% dengan kelayakan bila menghasilkan IRR diatas 10%, payback period yang ditunjukkan dengan masa pengembalian kurang dari umur proyek, dan PI yang menunjukkan kelayakan bila diatas 1. Mineral ikutan timah yang akan dilakukan peningkatan nilai tambah adalah  monasit, zirkon, dan ilmenit. Hasil pengolahan mineral ikutan timah pada penelitian ini yaitu monasit menjadi lanthanum oksida dan cerium oksida, zirkon menjadi micronized zircon, dan ilmenit menjadi titanium dioksida. Penelitian menunjukkan mineral ikutan layak diadakan investasi dengan nilai NPV monasit  Rp14.456.271.847; NPV zirkon Rp59.412.809.669; dan NPV ilmenit Rp74.697.631.175. IRR monasit 31,60%; IRR zirkon 37,49%; dan IRR ilmenit 34,59%. Payback period monasit selama 2,67 tahun,  zirkon selama 1,28 tahun, dan ilmenit 2,59 tahun. PI pengolahan mineral ikutan memiliki nilai di atas 1 dengan nilai PI monasit sebesar 1,70; zirkon sebesar 1,84; dan ilmenit sebesar 1,84.
