Abstract

This research aimed to develop a Convolutional Neural Network (CNN) model for automatic object color classification using MobileNetV2. To determine the optimal configuration, the training process adjusted several hyperparameters, with particular focus on identifying the most suitable learning rate. The dataset consisted of 3,212 images grouped into five color categories: red, green, blue, random (including yellow, orange, and brown), and none (no object detected). Data augmentation techniques were applied to enhance the variety and robustness of the dataset. The model was trained using the Adam optimizer alongside the categorical crossentropy loss function, with various learning rate settings tested during training. Evaluation results showed that the model worked best with a learning rate of 0.0001 and a batch size of 32, with an average accuracy of 94%. To display prediction results in real time, the top-performing model was integrated into a graphical user interface (GUI). These findings demonstrate the effectiveness of the MobileNetV2-based CNN model in recognizing object colors and highlight its suitability for integration into real-time industrial sorting applications

Abstract

Manual attendance systems in educational institutions, particularly in highly disciplined environments such as vocational schools with cadet programs, present significant challenges, including inaccuracy, administrative burden, and susceptibility to fraud. This study addresses these issues by designing and developing a secure mobile attendance application for the Android platform. The development process followed the Waterfall software development model, providing a structured framework from requirements analysis through testing. The proposed solution incorporates a dual-validation mechanism combining Quick Response (QR) Codes for session-specific identification with Geolocation technology to verify users’ physical presence within the designated school area. The application supports multiple user roles, including students, teachers, administrators, and parents, and offers automated attendance tracking for daily roll calls and extracurricular activities. It enables teachers to input attendance for in-class sessions manually. Empirical evaluation confirmed that the application effectively mitigates vulnerabilities inherent in the manual system. The dual-validation approach substantially enhances both the integrity and efficiency of the attendance process, offering a reliable and secure tool for monitoring student discipline. This study provides a practical model for integrating accessible digital technologies to strengthen administrative processes in secondary education contexts.

Abstract

E-voting adalah sistem pemungutan suara elektronik yang memanfaatkan teknologi seperti komputer atau perangkat seluler untuk mempermudah proses pemilihan dan mengurangi risiko kecurangan serta kesalahan manusia. Dengan e-voting, proses perhitungan suara lebih cepat, biaya pencetakan surat suara bisa dihemat, dan peralatan dapat digunakan berulang kali. Namun, e-voting memiliki kelemahan dalam hal keamanan, seperti potensi perubahan surat suara dan manipulasi data pemilih. Blockchain, khususnya Ethereum local blockchain Ganache, dapat mengatasi beberapa tantangan ini dengan meningkatkan keamanan data pemilihan. Penggunaan model prototype dalam pengembangan e-voting membantu memperjelas spesifikasi dan kebutuhan sistem.

Abstract

Elections are a democratic activity in Indonesia which are carried out every five years to elect leaders, but in the process of manual election calculations, the results are leaked and can cause data security problems. Through this research, we can provide solutions by implementing blockchain technology in election applications that will provide security for election results data stored on the blockchain. Blockchain technology is a chain of data blocks that are connected to each other by peer to peer. This application uses the Solidity programming language and uses a local ethereum blockchain database (Ganache). The method used in making this application is the waterfall method with Unified Modeling Language (UML) modeling where the visual modeling method is in object-oriented system design. From the results of testing the blockchain system for this application, it is found that blockchain can help secure election results very securely, where every result data will be stored in every block in a decentralized blockchain network.

Abstract

The sales strategy determines the continuity of the business being run. The problems that occur are the sales archive data has not been analyzed in-depth, the information system has not been integrated with applications for sales data analysis, online media promotion has not been maximized, inadequate stock of goods, the layout of goods is not optimal, and the combination of the number of products is not optimal. This study aims to extract hidden information in the sales database using Data Mining. From the information generated, sales strategy recommendations are developed relating to promotions, inventory, catalogue design, item layout, and the combination of product quantities. The method used is the association rule with Apriori algorithm to find consumer purchase patterns through the resulting association. The importance of association can be identified by two benchmarks, namely support and confidence. The sales strategy analyzed includes product promotion, catalogue design, product layout, stock predictions, and product combinations for sale. Based on the research produced 7 strong rules which are the highest association rules which are then developed into a sales strategy recommendation.
