Abstract

Halal products are obligatory to be used by people who are Muslim. When viewed in terms of the number of the Muslim population in the world and Indonesia, halal products have very potential economic opportunities. However, halal products have the risk of becoming non-halal if the accompanying process and storage do not follow halal rules. Therefore, it is necessary to identify the critical halal point, the point where the potential for such change occurs. So far, identification is made manually, of course there will be opportunities for identification errors to happen and it will take a relatively long time. To overcome these problems, identification can use a computer-based system. Forward chaining is an algorithm that is suitable for identifying halal points, because in SJH LPPOM MUI there is a decision tree for identifying halal critical points which is carried out in the same forward sequence as the forward chaining algorithm process flow. The development of a halal critical point identification system is carried out using the Software Development Life Cycle V-model method, the PHP programming language and the MySQL Database Management System. The system was successfully tested using Whitebox testing, including unit testing, integration testing, and overall system testing. Then testing using Blackbox testing techniques by comparing the results of identifying critical points using the system with the results of identifying critical points manually producing the same results. User satisfaction testing was also carried out using the End User Computing Satisfaction method and obtained an average satisfaction score of 86.53%Keywords – halal products, critical halal point, AI, forward chaining

Abstract

This study aims to obtain an efficient distribution route to produce an optimal total mileage. The research was conducted at PT. XYZ which is one of the fertilizer producers in Sidoarjo, East Java. During the Covid-19 pandemic, the company experienced a decline in demand, so it was necessary to plan distribution routes based on fleet capacity. This research is focused on NPK Blending fertilizer products due to the high interest from the market and the company's frequent production and distribution of these products. The company distributes products to 42 buffers spread across East Java. The number of buffers results in many routes that must be passed so that companies need to do careful planning to produce optimal routes. So far, the company does not have the right method for planning distribution routes. In solving this problem, the researcher uses the differential evolution algorithm method. The company has 17 distribution routes with a total mileage of 4791,2 km, while the results of data processing using the differential evolution algorithm obtained 9 distribution routes with a total distance of 3594,4 km and obtained a mileage savings of 26% so that the use of the differential evolution algorithm can provide a more optimal distribution route. from the company route.Keywords – Distribution, Differential Evolution Algorithm, Vehicle Routing Problem

Abstract

Kedurus river is located in a residential and agricultural area in the Wayang sub-district, Surabaya. Domestic and non-domestic activities around the river have provided excessive pollutants to the river, more than the standard contents as regulated by the government. This study is aimed to measure the pollution level in the river. Regulation PP 22 of 2021 is used as a quality standard while the capacity to accommodate pollution loads is calculated based on Kempten-LH No. 110 of 2003. Based on the research results, the DO, TDS, BOD, COD, and Ammonia parameters at points 1, 2, and 3, and the TSS and detergent parameters at point 3 indicated concerns for the quality of the water environment. This can be seen from the measurement values that exceed the pollution load capacity limit in accordance with class II quality standards, Government Regulation No. 22 of 2021. Appropriate measures are needed to improve the condition of the water environment to protect the health and survival of the living things in the river and maintaining the sustainability of aquatic ecosystems.Keywords – Pollution Load Capacity, Kedurus River,
