Abstract

Sampah plastik masih menjadi masalah yang tidak dapat disepelekan sampai saat ini. Banyak upaya yang dilakukan untuk menangani permasalahan tersebut. Hingga saat ini proses pirolisis sampah plastik masih terus diteliti. Pirolisis adalah proses konversi sampah plastic menjadi bahan bakar minyak melalui proses pemanasan pada suhu tinggi tanpa oksigen. Selain menghasilkan minyak, proses pirolisis juga menghasilkan zat padat dan gas buang. Pada gas buang pirolisis masih mengandung CO2 yang tinggi. CO2 merupakan zat pengotor yang dapat menurunkan nilai kalor. Tujuan dari penelitian ini yaitu untuk memaksimalkan proses purifikasi gas buang pirolisis. Proses purifikasi dibagi menjadi dua bagian yaitu absorber dan adsorber. Absorber adalah penyerapan menggunakan zat cair(larutan) sedangkan adsorber adalah penyerapan menggunakan zat padat. Pada penelitian kali, purifikasi menggunakan bahan larutan NaOH sebagai bahan absorber, dan bahan adsorber menggunakan steel wool, zeolit, arang aktif, dan silika gel. Sedangkan untuk proses pirolisis menggunakan plastik jenis LDPE (Low Density Poly Ethylene) yang sudah dicacah.

Abstract

To support product delivery, there is a need for distribution centers to send in a timely manner to various regions in Java Island. Research at PT. XYZ has a goal to determine the location of distribution centers that are effective and efficient in terms of minimizing transportation costs, because currently there are only old warehouses that are too far from distributors, with this distribution center, we can find out the cost comparison of product delivery to the intended distributor, and can also find out whether the center of gravity method can be applied to PT. XYZ or not. The case study of this research is product delivery in the East Java region by collecting product delivery data at PT. XYZ. This study uses Google Maps software to determine the coordinates of each customer, then calculates and processes the data using the Center of Gravity method. The research results obtained are the location of the new distribution center which is located in Kebontemu Hamlet, Peterongan District, Jombang Regency. With the new distribution center optimized by grouping, the effect on reducing transportation costs is 47%, and distances are 54%.
