Lubuk Karet Village has great potential in rubber production. However, the rubber sales process is often faced with various obstacles, such as difficulty in determining the right price and lack of transparency in transactions. This study is an analytical study using a qualitative approach. The aim is to analyze and design a prototype of a rubber sales application. This study uses questionnaires and interviews as the main data to answer research questions. The output of this study is the identification of problems and concerns of farmers related to how to calculate market prices, difficulties in recording transaction history, and minimal transparency of information regarding selling prices in the wider market. Then the second finding is regarding the prototype design of a prospective rubber sales application which will later be further developed by researchers. From the results of the analysis in this study, it is hoped that there will be further development of the application with farmer data entry features, rubber price calculations, and transaction tracking. It is hoped that this application can provide convenience for farmers in selling their crops, increase farmers' income, and provide transparent information regarding market prices. In addition, this application can also be a promotional media for local rubber products.

This study aims to develop an intuitive and efficient smart home control system by utilizing hand tracking and speech recognition technologies. These technologies employ the OpenCV, Mediapipe, PyAudio, and Speech Recognition libraries to recognize hand gestures and voice commands in real-time. The system is developed using a Raspberry Pi connected to a webcam and microphone as input devices, and a relay to control electronic appliances. The results show a high accuracy rate at optimal light intensity for hand tracking and a specific distance for speech recognition. This system is implemented in an IoT environment to control devices such as lights and door locks. The research is expected to contribute to the development of smarter and more user-friendly smart homes.

The manual attendance system using paper at work locations other than offices at PT Gresik Migas creates challenges in the effectiveness and efficiency of employee attendance records. This study implements a web-based attendance system that integrates geolocation and selfie features to improve the accuracy and efficiency of attendance recording. The system was developed using native PHP for backend, jQuery for frontend, MySQL as database, and Leaflet JS for geolocation implementation. Implementation results show the system was successfully implemented in 5 different locations with a 50-meter validation radius and used by 40 employees. This system enables real-time attendance monitoring through an admin dashboard and produces more efficient attendance records compared to the previous manual system.

This research aims to develop the company website PT. Rantangin Digital Indonesia uses the latest technology, namely Next.js and Tailwind CSS. This website development was carried out to increase visibility and user experience in accessing the services offered by the company.

The development results show that the website built has succeeded in fulfilling the company's goals of providing a digital platform that is easy to access, responsive on various devices, and has optimal performance. By using Next.js and Tailwind CSS, website development can be done efficiently and effectively, and provide a better user experience. Recommendations for further development include integration with content management systems and analytical features for monitoring website performance.

The Electronic Medical Record Information System (RME) is an information technology solution used to manage patient medical record data digitally, replacing manual recording systems that are prone to errors and data loss. This report discusses the design and implementation of the Electronic Medical Record Information System (RME) at the Community Health Center, which aims to increase efficiency, accuracy and security in managing patient medical records. This system includes recording medical data, treatment history, diagnosis, drug prescriptions, as well as integration with other health service systems. With RME, the medical service process at the Community Health Center is expected to be faster, more transparent and organized. This research uses a web-based system development method with database-based programming, which allows medical record data to be managed centrally and easily accessed by authorized medical personnel. The results of implementing this system show a significant increase in speed of service as well as a reduction in administrative and medical errors.
 

This paper aims to overcome the problem of manual financial recording that is still commonly used by MSMEs, which often causes data loss and inefficiency in financial management. To answer this challenge, researchers developed a mobile-based financial recording application using Flutter and a number of available supporting packages. This application is designed to be able to record and store income and expenditure data directly on the user's mobile device, making it easier for MSMEs to monitor their financial condition in real time. The development was carried out using a waterfall model approach, which includes the stages of analysis, design, implementation, and testing. To test the functional performance of the application, the Black Box testing method is used to assess the accuracy and reliability of the features without looking at the internal code structure. The test results show that all features can function as they should and the application is considered effective in supporting digital MSME financial recording.

The increasing waste problem requires innovative solutions that are efficient and sustainable. This study aims to design and build an Internet of Things (IoT) based garbage cleaning robot that can be monitored and controlled remotely. This system is designed by utilizing a microcontroller as the main brain, sensors to detect the presence of garbage, and an IoT-based communication module that allows monitoring and control of the robot via mobile devices or the web. Based on the results of the analysis and testing carried out, this study shows that the use of ESP8266 in the RC Trans Robot motor control with the Blynk application has succeeded in significantly increasing system efficiency. The system successfully responds to user input via a mobile application and can control the movement of the robot in real-time. The performance of the robot system controlled via a WiFi network shows good stability in various test scenarios. The robot can operate effectively within a distance that matches the range of the WiFi network, with fast control response and reliable communication.

Determining the best hosting service provider is a very important first step in starting a digital business. Mistakes in choosing a hosting service will have fatal consequences for the continuity and smooth running of a digital business. This research aims to select the best hosting service in the form of a Decision Support System (SPK). Determining the best hosting service provider is very important because hosting is one aspect that determines the success of an e-business. This research uses the PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation) method to determine the ranking of the best hosting service providers. The performance assessment of hosting service providers was carried out from January to April 2024. This research was carried out using data from 9 alternatives and 5 criteria which are crucial aspects in hosting services, namely, loading time, server uptime, number of downtimes, support and user friendliness. In this research, it was found that the hosting service provider Niagahoster was the first ranked alternative with a net flow value of 0.75.
