Abstract

Product shipping is important in the economic process in the company. Efficient product shipping routes should provide low transportation costs. This study based on a case company of CV. Kayana, a distributor of “Sari Roti”, has 4 motorbikes and 2 cars. Each vehicle has their own shipping routes. Nowadays, high distance for each route results on high transportation cost. Therefore, the objective of this study to minimize the distance and cost of product shipping by developing shipping algorithm using Particle Swarm Optimization (PSO) for Traveling Salesman Problem (TSP). The MATLAB software was employed to solve this problem. The solution is obtained by varying the amount of particles and number of iterations. Experimental results proved that the developed PSO is enough effective and efficient to solve shipping routes problem. The results show the proposed model have lower distance and transportation cost. It helps the company in determining the routes for product shipping with minimum transportation cost.

Abstract

Jetis Batik Village is a Sidoarjo batik center that produces typical Sidoarjo handwritten batik. The batik processing process produces textile waste which must be processed before being discharged into the environment. Many producers, both large and household scale, have one thing in common, namely producing liquid waste, containing dyes, suspended solids, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Total Dissolved Solids (TDS) that need to be managed before being discharged into water bodies. One way of processing that can be done is by using adsorbents. Lapindo mud and Blood Clam shells are abundant natural materials that can be used to process textile waste. Varying adsorbent mass ratios were carried out to determine the optimal adsorbent ratio for processing textile waste. Variations in mass of Blood Clamshells and Lapindo mud (1:0, 0:1, 1:1, 1:2, 2:1). The best variation in reducing COD was variation C (1 g Lapindo mud and 1 g Blood Clam shell) with a removal efficiency of 89.13%. The best variation in reducing TDS is variation E (2 g Lapindo mud and 1 g Blood Clam shell) with an efficiency of 86.07%. The TSS removal efficiency showed relatively the same results 33.33%.
