Abstract

Water is a natural resource important for life and daily activities. Water distributed by the Regional Drinking Water Company (PDAM) should include a coagulation process using liquid aluminum sulfate as a coagulant before it can be consumed. Therefore, this research aims to predict the need for liquid aluminum sulfate in PDAM from 2023 to 2024 using Holt-Winter's method. It also aims to evaluate the optimum liquid aluminum sulfate chemical inventory policy using Q probabilistic inventory model with Normal and erlang probabilistic distributions in PDAM. The data was obtained from Tirta Musi PDAM in Palembang City, Indonesia. The results of forecasting liquid aluminum sulfate demand level data with the Holt-Winter multiplicative method provide the smallest MAPE value. The erlang probability distribution assumption has been met through the Kolmogorov Smirnov test method. The erlang probabilistic inventory model provides a more optimal policy solution than the normal probabilistic inventory model, with minimum total cost and higher service level.

Abstract

In this study, an inventory model is developed for pharmaceutical products that deteriorate over time with an exponential demand rate. The discussion of exponential demand is rarely explored but has the advantage that the demand value toward total cost remains positive. This study assumes allowable shortages and complete backlogging, making it necessary to design an optimal policy for deteriorating goods with an exponential demand rate. The model shows that the initial stock decreases over time, potentially leading to shortages before the next order arrives. The optimal solution indicates that the inventory reaches the zero point at ????1 = 0.0000011 and the cycle length ????1 = 0.012 resulting in an average minimum total cost of ????????̅̅̅̅ = $17,133.9 per cycle by Wolfram Alpha. Sensitivity analysis measures the changes of the results in the increasing value of ????????̅̅̅̅ for all parameters. Exponential function variables (???? and ????) produces ????1 and ????1 stable values. On increasing the cost of each damage (????????) and constant damage rate (????) produces a ????1 stable value, but the value of ????1 increases. An increase in storage costs (h) results in a decrease in the value of ????1 and ????1. Increasing in the cost of shortages (s) resulted in an increase in the value of ????1 and a decrease in the value of ????1.

Abstract

Optimasi merupakan salah satu kajian dalam terapan Matematika yang bertujuan untuk mengoptimalkan suatu keadaan. Salah satu masalah yang dapat diaplikasikan dalam optimasi adalah masalah rute. Masalah nyata yang dapat diterapkan dalam kehidupan sehari-hari adalah permasalahan rute pengangkutan sampah. Pada permasalahan rute pengangkutan sampah dapat digunakan konsep Vehicle Routing Problem (VRP). Konsep optimasi pengangkutan sampah menggunakan konsep VRP merupakan salah satu konsep yang cukup populer di kalangan mahasiswa, namun konsep VRP sendiri tidak terlalu dibahas secara mendalam dalam perkuliahan. Oleh karena itu kegiatan ini bertujuan untuk memberikan pemahaman mahasiswa dalam menggunakan konsep VRP dalam masalah pengangkutan sampah.
