Abstract

Agrarian reform is a strategic program aimed at improving land ownership distribution and enhancing community welfare. One crucial stage in this program is determining the eligibility of Tanah Objek Reforma Agraria (TORA), which requires an objective and structured selection method. This study develops a web-based system that implements the Simple Additive Weighting (SAW) method to assess TORA eligibility more efficiently and transparently. The SAW method is chosen because it provides systematic calculations by considering various established criteria, such as land legal status, land use, and social and economic potential. This system enables policymakers to manage and analyze data more effectively, thereby supporting accurate and fair decision-making in the implementation of agrarian reform. The study results indicate that a web-based approach using the SAW method can improve accuracy and efficiency in determining TORA eligibility, offering a more structured solution for agrarian reform programs in Indonesia.

Abstract

This study uses the PIECES framework, which has six important aspects: Performance, Information, Economy, Control, Efficiency, and Service, to assess the shipment tracking system on the Shopee Express website. Direct observation and system testing serve as the foundation for the study's qualitative descriptive methodology. The system's accuracy in displaying real-time tracking information and its performance on stable networks are demonstrated by the results. However, a number of drawbacks are discovered, including restricted service responsiveness on sluggish connections, no progress feedback during data loading, and no input validation. The system lacks user assistance features like history tracking and interactive guidance, despite being cost-effective and available without a login. The PIECES framework is a useful tool for determining web-based logistic tracking systems' advantages and shortcomings.

Abstract

Data classification is one of the important techniques in data mining and machine learning, which is widely used to group data into certain classes. This study aims to analyze and compare the performance of three classification algorithms, namely K-Nearest Neighbor (K-NN), Naive Bayes, and Decision Tree, in classifying Iris data from the UCI Machine Learning Repository. This dataset consists of 150 data with four feature attributes and three target classes. Testing was carried out using the cross-validation method with a k-fold approach of 10 folds. The results of the performance evaluation were measured using the metrics of accuracy, precision, recall, and f1-score. Based on the test results, the K-NN algorithm showed the highest accuracy rate of 96.67%, followed by Decision Tree at 95.33%, and Naive Bayes at 94.00%. These findings indicate that choosing the right classification algorithm can affect the success rate in the data classification process.

Abstract

Posyandu is a primary healthcare service that plays an essential role in monitoring child growth and maternal health in communities. However, manual record-keeping still used by “Bintang Timur” Posyandu in RW 17, Sendangmulyo Subdistrict, Semarang City, has led to delays in data processing and reporting. This study aims to design and develop a web-based information system to enhance the efficiency and accuracy of Posyandu data management. The system was deveIoped using the WaterfaIl model and built with PHP, Laravel, and MySQL technologies. The results show that the system effectively manages child data, visit records, immunizations, and generates digital reports. The implementation of this system accelerates data entry, minimizes errors, and facilitates easier access to information for cadres and related parties. Therefore, the system is expected to support more effective, transparent, and sustainable healthcare services.

Abstract

This research introduces an IoT-based speed control system tailored for ambulance vehicles using the NodeMCU ESP8266 microcontroller. The system employs an optocoupler sensor to detect wheel rotation speed and transmits real-time data via Wi-Fi to the Blynk application. The objective is to ensure that the ambulance maintains safe operating speeds, while simultaneously activating alerts for the driver whenever thresholds are exceeded. Performance evaluations were conducted across GPRS, 3G, and 4G networks to assess reliability and responsiveness. The findings reveal a response latency of approximately 1 second on a 4G connection, and up to 3 seconds under GPRS. The proposed system exhibited strong network stability over a 24-hour test period and delivered accurate speed monitoring throughout. The novelty of this work lies in the seamless integration of real-time monitoring and alert mechanisms without reliance on manual intervention. This solution has potential application in improving the operational safety and efficiency of emergency medical transport services in Indonesia.

Abstract

Neural networks represent a widely adopted paradigm within the domain of machine learning, employed for a multitude of classification endeavors, encompassing image recognition and natural language processing. This investigation seeks to elucidate the influence of varying neuron quantities in hidden layers on the efficacy of neural networks in both binary and multi-class classification endeavors. The research utilizes a dataset procured from images depicting characters and digits, which were transformed into binary format via a thresholding methodology. The neural network architectures comprise one and two hidden layers, which are trained employing the backpropagation algorithm in conjunction with the Adam optimizer. The evaluation of the models is conducted through metrics such as accuracy, loss curves, and confusion matrices. Findings reveal that the configuration featuring two hidden layers with 40 sampai 99 neurons achieves the pinnacle accuracy of 99.64 percent alongside optimal loss stability. Furthermore, models incorporating a single hidden layer exhibited commendable accuracy, thereby indicating that a reduced number of neurons can proficiently encapsulate data complexity in less demanding tasks. This research underscores the criticality of selecting suitable neural network configurations contingent upon data complexity and classification objectives, while advocating for further investigation into regularization strategies to enhance performance.

Abstract

The development of renewable energy systems is a major focus in efforts to reduce environmental impacts and dependence on fossil energy sources. One promising renewable energy source is solar energy, which can be utilized through photovoltaic technology. However, to increase the efficiency of the photovoltaic system, an accurate estimate of the output power produced is required. This study aims to develop a photovoltaic output power estimation model using MATLAB-based Genetic Algorithm (GA). Genetic Algorithm was chosen because of its ability to find optimal solutions to a problem using the principles of natural selection. In this study, parameters that affect the performance of the photovoltaic system, such as sunlight intensity, cell temperature, and panel tilt angle, will be analyzed and modeled. The results of this photovoltaic output power estimation model are expected to provide more accurate predictions, so that they can be used for decision making in the planning and development of solar energy systems. Through simulation and data analysis, this study is expected to make a significant contribution to the development of photovoltaic technology in Indonesia and increase the efficiency of its use.

Abstract

Badminton is one of the most popular sports in the world, with Indonesia having achieved great success in international competitions. The high level of public interest in this sport requires the availability of adequate court facilities. However, the comfort of badminton court facilities still varies, so a decision support system is needed to help select the optimal court. This study develops a decision support system based on the integration of the Simple Additive Weighting (SAW) and Analytical Hierarchy Process (AHP) methods. SAW is used for criterion weighting, while AHP is applied in the ranking stage of alternatives. This combination of methods was chosen due to its ability to process qualitative data from player and athlete evaluations, as well as quantitative court data, while addressing complex issues through hierarchy-based prioritisation. The results of the study indicate that the system is capable of consistently weighting criteria (CR < 0.1). This study also produced a ranking of badminton courts in North Brebes based on seven criteria (price, floor type, lighting, bathrooms, scoreboards, cooperatives, and parking lots) and identified priority facilities. Court 33 in Brebes was selected as the best alternative with a preference value of 0.7485.
