Abstract

The development of information technology has driven major changes in corporate promotion and communication strategies, one of which is through the use of company profile websites. This study aims to design and implement a web-based company profile website for PT Mitra Makmur Global; a company engaged in the heavy equipment rental sector. The research method used is a qualitative method with a Waterfall system development model, which includes the stages of needs analysis, system design, implementation, testing, and maintenance. The website is designed to provide information about the company profile, vision and mission, services, and contacts in an interactive and easily accessible manner. The implementation results show that the company profile website is able to improve the company's professional image, expand the reach of promotions, and make it easier for potential clients to obtain information related to the company's services. In addition, the implementation of a responsive interface design and structured navigation makes users feel more comfortable in navigating the site. In conclusion, the development of the PT Mitra Makmur Global company profile website plays a significant role in strengthening the company's digital presence, increasing customer trust, and becoming an effective promotional tool in the digital era.

Abstract

Electrical energy efficiency is an essential requirement in supporting environmental sustainability. Lamps, as one of the most frequently used electrical devices, contribute significantly to energy consumption in both households and industries. This study aims to design an Internet of Things (IoT)-based current monitoring system for lamps using the Blynk application. The system is built using a NodeMCU ESP8266 as the main controller and a PZEM-004T sensor as a measuring tool for voltage, current, power, and energy. The test results show that the system can operate in real time to monitor electrical parameters and display data through the Blynk application on a smartphone. The measurement accuracy reaches ±3.8%, with influencing factors including voltage stability and internet connection quality. This system has proven effective as an electrical energy monitoring solution that supports energy conservation and electrical safety.

Abstract

The increasing demand for sustainable agriculture in Indonesia and challenges like land scarcity and inefficient resource use have driven interest in innovative farming technologies. This study investigates the comparative effectiveness of an innovative farming-based aeroponic system versus a conventional soil-based system in cultivating green chili. A quantitative experimental design was employed, using IoT-integrated sensors in the aeroponic setup to monitor and control environmental parameters, while the conventional system relied on manual practices. Key growth indicators, including plant height, number of leaves, and wet and dry weight, were measured over a 30-day day. Statistical analysis revealed that the aeroponic system significantly outperformed the conventional system across all parameters (p < 0.05), with dry weight showing the most substantial improvement. These findings underscore the potential of smart aeroponics in enhancing crop productivity and resource efficiency. However, cost, energy dependency, and scalability considerations must be addressed to enable broader adoption. The study contributes to the growing body of evidence supporting precision agriculture as a viable strategy for sustainable food production.

Abstract

Conventional English vocabulary learning methods, such as memorizing word lists, are often considered less effective because they offer little interactivity and provide no immediate feedback. This study aims to design and develop the Vocaup! website, an English–Indonesian vocabulary learning platform equipped with interactive flashcards, quizzes, pronunciation audio, and progress tracking. The system was developed using a Research and Development (R&D) approach with the Waterfall model, covering requirements analysis, system design using UML, implementation using native PHP and MySQL, black box testing, and evaluation and improvement. The system provides illustrated flashcards with audio, quizzes with translate, listening, and arrange-words question types, a guest mode, login to store learning progress, badges as a gamification element, and an admin panel to manage user data, vocabulary, and quiz questions. The results show that the Vocaup! website provides an interactive and easy-to-use vocabulary learning medium, and all features work according to user needs and support independent learning. The website is expected to serve as an accessible digital learning alternative for a wide range of learners.

Abstract

Automatic water dispensing technology can reduce direct contact with dispenser surfaces and support better control of water use. This study aimed to design and develop an automatic water dispenser using an HC-SR04 ultrasonic sensor and Arduino Uno to improve hygiene during the water dispensing process. The research used a design and development approach consisting of problem identification, literature study, hardware and software design, prototype assembly, system integration, testing, and evaluation. The HC-SR04 sensor was used to detect the presence and distance of a glass, while the Arduino Uno processed the sensor readings and controlled a water pump through a relay. System testing was conducted at several glass detection distances and through repeated measurements of the volume of water dispensed. The results showed that the sensor detected a glass at distances of 3, 5, 7, and 10 cm, while an object positioned beyond 12 cm was not detected. Five water volume tests produced 190, 195, 200, 192, and 198 mL, with an average volume of 195 mL per filling cycle. Functional testing also showed that the pump turned on when a glass was detected and turned off when the glass was removed. These findings indicate that the prototype operated according to the designed system and enabled water dispensing without direct contact. In practical terms, the system can support more hygienic dispenser use and reduce unnecessary water flow by activating the pump only when a glass is detected. Further development can focus on water-level monitoring, IoT integration, enclosure improvement, and longer testing.
