Abstract

Classroom is a place that use by student to learn. Each classroom equipped by electrical equipment and tool including 4 lamps and 2 fans. When learning activities is over in some classroom, lamps and fans still on. The cause of this condition is due to manual control, the result is electricity to be wasteful. As a result, electricity supply is run out before one month use and it can obstruct the learning activities if the power goes out. The aim of the research is to build a system that able to controls electricity equipment in the classroom and make a monitoring power consume remotely so can be effective and efficient. The system design is use prototype method that is a design software technic, while in designing web, with Data Flow Diagram (DFD) and Entity Relationship Diagram (ERD). Control design and monitoring use Raspberry Pi 3 B+ as microcontroller and web as interface user media. Relay connected with raspberry pi through General Purpose Input Output (GPIO) as automatic switch. USB Converter serial as interface for communicating raspberry pi with PZEM-004T module as current, voltage and power reader. The result of the study Can control and monitor the use of power consume in electrical equipment remotely web based. The system is completed by daily report of power consume and warning notification on the web when kWh almost running out. This research is useful in preventing wasting electricity and running out of electricity while learning is in progress

Abstract

The Internet of Things (IoT) is a concept aimed at expanding the benefits of continuous internet connectivity. IoT can be utilized for monitoring the intensity of light, temperature, and air humidity in the surroundings to determine suitable locations for the placement of solar panels. Solar panels are made of semiconductor materials capable of converting solar energy into electricity. The primary issue with using solar panels is that the power output they produce depends on the intensity of light captured by the solar panel. Additionally, the temperature and air humidity around the solar panel also influence its performance. The objective of this research is to create a system for measuring the intensity of sunlight, humidity, and temperature for the placement of IoT-based solar panels using LDR and DHT 11 sensors. The development of this system involves the use of the Prototyping Method. The device's design incorporates the NodeMCU ESP32 microcontroller, and monitoring is conducted through a smartphone using the Blynk application. The LDR and DHT 11 sensors are connected to the NodeMCU ESP32's GPIO as data receivers. A WiFi network is used to transmit intensity of light, temperature, and humidity data from the NodeMCU ESP32 to the smartphone, where it is displayed through the Blynk application. This research is beneficial for identifying the most suitable locations for solar panel placement. Keywords : IOT, Solar panel, Monitoring, NodeMCU ESP32, Blynk

Abstract

Decision Support Systems (DSS) or Decision Support Systems (DSS) is an information system that is flexible, interactive, can be adapted and developed to provide information, modeling and data manipulation so that it can produce various alternative decisions and answers to assist management in dealing with various problems that arise. semi-structured and unstructured situations, where no one knows for sure how decisions should be made. One method that can be used is the Analytical Hierarchy Process (AHP) method. This method was chosen because it can describe complex multi-factor or multi-criteria problems into a hierarchy that is implemented in the selection of insurance products using the AHP method. With this method it is expected to be able to choose the right product because it is based on predetermined criteria and weight values so that it will get maximum results.

Abstract

The use of a decision support system (DSS) can help someone in making accurate and targeted decisions. Many problems can be solved by using this decision support system, one of which is to assess the performance of lecturers. In determining the assessment of lecturer performance, there are several criteria that must be possessed by each individual to be used as an assessment of lecturer perfomace. The method that can be used for this decision support system is the Simple Multi-Attribute Ratting Technique (SMART) method. This study aims to provide an ssessment of the performance of lecturers at STT Wastukancana to improve the quality of internal and external services.

Abstract

The growing cafe industry in Purwakarta presents challenges for customers in choosing the right cafe due to various factors such as distance, food prices, and service quality. This research aims to develop a Decision Support System using the MOORA method to efficiently recommend the best cafes based on predefined criteria. The research involved collecting data about cafes, analyzing the problem, and applying the MOORA method to rank cafes according to relevant criteria, such as distance, price, facilities, and service quality. The findings show that the MOORA method is effective in ranking cafés in Purwakarta, with cafés that get the highest score fulfilling the criteria of distance, price, facilities, and service quality, thus being recommended as the best choice for the community. This study concluded that the best café recommendation in Purwakarta is café salbeans park with the highest score of 0.093. In other words, café salbeans park is the best alternative. and it is recommended that this system be widely implemented and updated regularly to include the latest information about cafes, improving user experience in decision making.

Abstract

Environmental management in Cluster Cahaya Mekar Wangi is still manual, utilizing WhatsApp and Excel for dues recording, financial reports, and security tracking, which often results in data errors and low transparency. This study developed SIMLING, an Android-based application, to digitalize and integrate these processes into a unified system. Built using the Waterfall model with Kotlin (frontend), Golang (backend), and MySQL in Docker (database), SIMLING offers real-time payment recording with receipt uploads, automated validations, transparent reports, QR-based security monitoring, and centralized notifications. The implementation shows SIMLING streamlines administrative tasks, improves transaction validation, and enhances security monitoring, while providing residents with easier payments and clear financial information. This supports smarter, more structured, and sustainable community management.
