Abstract

This study aims to determine the water quality of the Cimarinjung River in the Ciletuh Geopark area, Ciwaru Village. The method used in the study was a survey method by taking samples at one location of Cimarinjung River water samples. The results of the study found that the water quality of the Cimarinjung River had some parameters that did not meet the standards required in the water quality standards in Government Regulation Number 22 of 2021 concerning the Implementation of Environmental Protection and Management (Appendix VI concerning Class 1 National Water Quality Standards). Shown by water quality in physical parameters, namely the total solids are sorted by 1369 mg/l which is not in accordance with the requirements (1000 mg/l). The water quality for chemical parmeter, chloride (Cl), was 9340 mg/l exceeding the required limit (300 mg/l). The quality of the biological parameter is APM Esherichia Coli 350 APM/100 ml which exceeds the required limit (100 APM/100 ml).

Abstract

This research aims to assess the effectiveness of inventory control applied by Mie Ayam Pahlawan in optimizing production costs and determining the economically optimal order quantity for raw materials, as well as minimizing the total inventory cost. The study employs a quantitative descriptive method, focusing on the company within a specific timeframe, gathering data and information relevant to the research objectives. Descriptive analysis techniques are utilized to analyze data related to raw material inventory control issues in efforts to reduce production costs, using the Economic Order Quantity (EOQ) and Period Order Quantity (POQ) methods. The findings indicate that the company can achieve cost savings by adopting the POQ method, where ordering costs are lower compared to the EOQ method or the current method employed by the company. The frequency of raw material purchases using the company's method is higher than the POQ method (Period Order Quantity).
