Abstract

This study aims to design and build a web-based employee attendance and payroll information system at CV Expressa to overcome problems arising from manual processes, such as late salaries, data recapitulation errors, and lack of transparency. The method used is the System Development Life Cycle (SDLC) waterfall model approach, which includes needs analysis, system design, implementation using the Laravel framework and MySQL database, testing with the blackbox method, and maintenance. The results of the study show that the system built is able to automate GPS-based attendance recording and salary calculations, accelerate data recapitulation, and provide independent payslip access for employees. This system also succeeded in increasing operational efficiency and data accuracy, as well as reducing administrative workload. However, this study has limitations in the scope of implementation which is still limited to one company and does not include advanced security features such as biometric authentication and mobile applications. Further development is recommended to improve the scalability and flexibility of the system.

Abstract

Wheeled robots have evolved significantly, starting from simple designs that utilized a single wheel for maneuvering to the present day, where there are numerous types capable of moving in all directions. The increasing complexity of wheeled robots today has created a learning gap for students who are just entering the world of robotics and the advanced robots that currently exist. Based on this problem, a mobile robot learning platform is needed to bridge their knowledge. The design of this platform is expected to help guide students’ learning of omniwheel robot kinematics in terms of robot model preparation, robot firmware design, communication design between the PC and the robot, and the implementation of kinematic formulas as robot commands. This platform is also designed to be universal, so it can be implemented for ready-made robots or robots built with any type of microcontroller. Comprehensive testing was performed for both movement modes in the application: forward kinematics and inverse kinematics. The forward kinematics test was carried out by assigning speed values to each motor individually. The inverse kinematics test was cariied out by assigning target position in cartesian plane. This platform is expected to serve as a valuable tool in the study of omniwheel robot kinematics.

Abstract

This study aims to analyze the performance of reclosers in improving the reliability of the 20 kilovolt distribution network at PT PLN (Persero) UP3 Lhokseumawe. The research focuses on optimizing the placement and delay time settings of reclosers based on fault current and network impedance. A comparative method was used involving manual calculations and simulation using ETAP 16.0.0 software. The object of study is the CD 12 feeder. The simulation evaluates fault currents and the corresponding recloser delay times at several bus locations. Results show that the closer the fault location to the power source, the higher the short-circuit current, which leads to shorter recloser operating time. Conversely, longer distances result in lower fault currents and longer delay settings. The analysis confirms that proper coordination and parameter settings significantly improve system protection and recovery. Moreover, differences between manual and simulation results emphasize the importance of digital tools in distribution network analysis. The study concludes that recloser configuration based on accurate load profiles and fault data enhances overall system performance and operational efficiency.

Abstract

Corn is one of Indonesia's food commodities, which is an alternative food that supports food diversification in Indonesia. However, leaf infections in corn plants often cause significant yield losses and threaten food security. Early detection of this disease is very important, especially for small farmers, because conventional diagnostic methods that rely on agronomists are expensive and time-consuming. Recent advances in Agricultural Artificial Intelligence (AI) and image processing have facilitated automatic plant disease recognition through Convolutional Neural Networks (CNN), with ResNet as the main backbone combined through concatenation with MobileNetV3, DenseNet161, and GoogleNet. The dataset consists of 4,000 images divided into 2,560 training data, 640 validation data, and 800 test data, with image sizes adjusted to 224×224 pixels. The dataset consists of 4,000 images distributed across four categories: gray leaf spot, common rust, northern leaf blight, and healthy leaf. The testing was conducted using three different optimizers, namely Adam, RMSprop, and SGD, with a learning rate of 0.01. The experimental results showed that the SGD optimizer provided the best performance with a loss value of 0.2275, accuracy of 0.9513, precision of 0.9536, recall of 0.9513, and F1-score of 0.9512. These findings confirm that the combination of ResNet, MobileNetV3, DenseNet161, and GoogleNet architectures with the SGD optimizer can significantly improve the accuracy of corn leaf disease detection, making it a potential application for automatic detection systems in support of smart farming practices.

Abstract

In developed countries, waste has been regarded as an important component of management systems as well as reuse practices. In contrast, developing countries, particularly Indonesia, still face various challenges in waste management. Approximately 60% of the total national waste generation originates from household waste, and about 39.98% of this amount has not been optimally managed. Processing organic waste into compost is an environmentally friendly alternative that can reduce waste volume while increasing the value of household and agricultural waste. However, conventional composting methods often encounter difficulties, especially in maintaining temperature and moisture stability, causing the decomposition process to be less optimal. Based on these issues, this study aims to design and implement an automated efficiency and monitoring system for compost processing based on the Internet of Things (IoT). The developed system utilizes an ESP32 microcontroller, a soil moisture sensor for moisture measurement, a DS18B20 sensor for compost temperature monitoring, as well as an automatically controlled water pump and a 12 V DC fan. Sensor data are transmitted in real time to the Blynk platform for remote monitoring purposes. The experimental results indicate that the system is capable of maintaining moisture levels within the ideal range of 50–60% and compost temperature within the optimal range of 30–40°C, enabling the composting process to operate more stably, efficiently, and in a controlled manner.

Abstract

The rapid development of multimedia technology has encouraged innovation in learning media, particularly for practical-based courses. Fiber optic practicum learning requires direct practice, specialized equipment, and adequate laboratory facilities, which often become constraints, especially during distance learning conditions. This final project aims to develop a virtual reality–based learning media for fiber optic practicum to support students’ understanding of practical procedures in a more interactive and immersive manner.The development process utilizes Blender as a 3D modeling and animation tool to design laboratory environments and fiber optic practicum equipment, including stripper, cleaver, fusion splicer, optical power meter, and fiber optic cables. Verge3D is used to create interactive animations and integrate the models into a virtual reality environment. The learning media simulates key practicum stages, such as cable stripping, cutting, splicing, and attenuation measurement using an optical power meter.The resulting virtual reality learning media allows users to experience fiber optic practicum activities in a simulated laboratory environment as if performing real practices. This media is expected to function as an alternative learning tool that enhances students’ understanding, motivation, and readiness before conducting actual fiber optic practicum in the lab.
