Abstract

Jenis penukar kalor sangatlah beragam dan masing masing dirancang untuk memenuhi kebutuhan yang spesifik. Namun demikian jenis shell & tube sejauh ini merupakan jenis yang paling banyak dipergunakan berkat konstruksinya relative sederhana dan memiliki keandalan karena dapat dioperasikan dengan beberapa jenis fluida kerja. Efek pendinginan yang dihasilkan dalam sistem perpindahan panas tergantung dari efektivitas kinerja kondensor. Sementara, kinerja kondensor semakin lama akan menurun seiring dengan terjadinya fouling factor. Pada penelitian ini dilakukan analisa perhitungan jumlah tube dan diameter tube pada kondensor sebagai Alat Penukar Kalor (APK). Dari hasil analisa perhitungan adalah jumlah tube 663 buah, diameter tube 40 mm, panjang tube 2,5 m.

Abstract

Plastic waste in the Seribu Islands has become a significant issue threatening marine and coastal ecosystems. This study analyzes the conversion of plastic waste into diesel fuel through pyrolysis, employing three scenarios of plastic mixture ratios: LDPE and PP, PET, PS, and HDPE. With operating temperatures of 400 °C, 480 °C, and 550 °C, the research evaluates energy efficiency, diesel output, and return on investment (ROI). Results indicate that a mixture of 50% LDPE and PP, 15% PET, 10% PS, and 25% HDPE at 550 °C produces the highest diesel yield of 0.805 tons per 1,000 kg of plastic. The annual ROI is recorded at 0.26%, highlighting the project's potential to support environmental conservation while providing economic benefits
