Design of a Desktop Java-Based Introduction to Basic Electronic Components

Ulil Albab — 2024-12-19

The development of information technology has had a positive impact on the world of education, one of which is to simplify the learning process. In the field of electronics, understanding basic components is an important foundation for students and practitioners. This Java Desktop-based application design aims to introduce basic electronic components with an easy-to-understand interactive interface. In this software, it contains various information about basic electronic components such as Resistors, Capacitors, Transistors, Diodes, Push Buttons, which is equipped with detailed information about the specifications and basic functions of various electronic components. In addition, the app comes with visual illustrations in the form of images that support the understanding of physical and component symbols. To explain how components in a series work, the app presents interactive animations to clarify the concept of how each component works and functions. During the creation and testing of 5 times, which was carried out using 5 different basic components resulting in different circuits and explanations of how to work, these results then obtained data from these 5 components which were then entered into the MySQL Database. The data present in the Driver Database is displayed using the Desktop-Based Java Programming Language.

Mohammad Humam — 2024-12-13

Studi kasus penelitian ini pada Politeknik Harapan Bersama yang nantinya digunakan untuk pengambilan keputusan mahasiswa penerima beasiswa. Tujuan penelitian ini untuk pengambilan keputusan penerima beasiswa. Penelitian sebelumnya sudah melakukan Sistem Pengambilan Keputusan (SPK) dengan metode TOPSIS (Technique for Others Preference by Similarity to Ideal Solution), oleh karena itu pada penelitian ini akan menganalisa perbandingan SPK dengan metode SAW dan metode TOPSIS untuk mencari model yang lebih baik dalam pengambilan keputusan penerima beasiswa. Diharapkan nantinya menghasilkan Solusi yang tepat dan mengetahui perbandingan dari 2 model yang terbaik dalam pengambilan keputusan penerima beasiswa pada penelitian ini hasil implementasi akan ditampilkan berupa website.

Design of Cashier Information System and Sales of Jaya Putra 04 Store Based on Website Using Waterfall Method

Muhamad Bakhar — 2024-12-13

In the digital era, the need for effective and efficient information systems has become increasingly important to support business operations. This study aims to design and develop a web-based cashier information system for Toko Jaya Putra 04 using the Waterfall method. The system is designed to address challenges in manual transactions, such as long queues, recording errors, and lack of stock visibility. The research stages include requirements analysis, system design using Unified Modeling Language (UML), implementation with PHP programming language and MySQL database, testing using the Black Box Testing method, and system maintenance. The results show that this cashier information system can improve transaction process efficiency, reduce customer waiting times, and simplify stock management and financial reporting. This system is expected to be further developed with additional features, such as digital payment integration, customer loyalty programs, and enhanced data security. By implementing this system, Toko Jaya Putra 04 can enhance service quality and support more strategic business decision-making.

Monitoring the Filtration of Brackish Water Into Raw Water by the Reserve Osmosis Method

Abdul Basit — 2024-10-15

The need for raw water is still a serious problem for coastal communities, where groundwater obtained by coastal communities cannot be categorized as suitable for use, because the water tends to be brackish. Clean water that is suitable for consumption is not only clear, odorless, and tasteless, but must also meet health requirements. The urgency of the condition in the coastal area is that with the development of housing located on the coast, the need for clean water is very important for people living on the coast. The purpose of this study is to implement appropriate technology in the coastal area of the north coast with the hope of providing raw or usable water for the people of the north coast, especially for the people in the coastal area of Tegal City, Central Java. The appropriate technology that will be applied is to monitor the results of an internet-of-things based filtration system by reading the TDS and PH sensor values. The TDS sensor can detect a decrease in moisture content with an average decrease in PPM value of around 321 and salinity or salt levels, which is an average decrease of about 8.63%, while the PH sensor detects an increase in the sample, which is an average of 1.8 with a water filling speed of 9.03 L/min. Thus, the previously brackish water condition can be used as an effort to overcome the raw water crisis in coastal communities with the reserve osmosis filtration method.
