Abstract

Dapur si Nyonyong is one of the home industries located in Padang City, engaged in the production of ready-to-eat snacks, particularly potato chips. The production system applied is a make-to-order production system. The fluctuating and uncertain customer demand in each ordering period requires Dapur si Nyonyong to be able to fulfill customer requests to produce potato chips according to the quantity demanded by customers. In this study, a dynamic system modeling of potato chips production is conducted to identify the interacting variables in the dynamic potato chips production process at Dapur si Nyonyong and analyze the potato chips production system's impact on the raw material requirements. The modeling is carried out using Vensim software. The results obtained are as follows: 1. The dynamic system model of potato chips production at Dapur si Nyonyong consists of interconnected variables. The factors that build the model include the customer demand subsystem, raw material subsystem, production subsystem, and cost and revenue subsystem. 2. Based on the simulation results for the next 2 years, potato chips production will increase by 33%. However, with a monthly raw material inventory of only 20 kg, production delays are expected due to the demand for production that exceeds the available inventory. The cost for raw material requirements also increases by 33%.

Abstract

In the discipline of computer science, artificial intelligence, commonly referred to as AI, is a subfield that tries to make machines (computers) capable of completing activities simultaneously with and in addition to those that are performed by people. Due to a lack of information regarding pregnancy illnesses in women, the symptoms that are experienced during pregnancy, as well as the significance of pregnancy and delivery services, there is a lack of understanding regarding the period during which the fetus is developing inside the womb. This has a substantial impact on the health of both the mother and the fetus, since it carries with it an increased chance of miscarriage and maternal death since the pregnancy is being maintained. With a system that diagnoses pregnancy disorders in women, it can be used for the consultation process to find out what symptoms are solutions for pregnancy. The forward chaining method can determine solutions based on symptom data. The study's goal is to create a web-based expert system to diagnose pregnancy disorders in women. symptoms that are selected by the user, and the system that has been developed is able to offer a solution to the difficulties that have been encountered.

Abstract

SMPN 40 Batam Library implements a library information system. Currently, because library data information management is still very conventional, errors in checking data and difficulties in finding data information still often occur in library data management. Along with the development of library needs, it is important to realize that the data management process, including member data, book data, data borrowing, data returning, and data library are still done manually. The main objective of implementing a library information system is to facilitate the smooth processing of data and information in the library, especially for library staff. This aims to ensure that book borrowers can more easily access various information related to the book collections available in the library. For digital library development, the first is small-scale development. The digital library application was created using Adobe Animate software and Adobe AIR as the programming language. The data collection method uses the waterfall method which is carried out in stages, namely needs analysis, design, implementation, testing and maintenance. Design stages use Unified Modeling Language (UML) such as use case diagrams, activity diagrams, sequence diagrams, and class diagrams. And system testing adopts black box testing. The research results show that the digital library system has succeeded in building Android-based applications that can be run on mobile devices. Digital library applications are more convenient for administrators to use, managing book data and querying book information and making library reports more efficient.
