Abstract

In general, CAPTCHA is an image containing distorted letters or numbers. This test involves users typing the results of guessing letters or numbers in the distorted image as security before users can enter or access a website they want to go to. In this paper, a simulation of an automatic reader system for CAPTCHA has been created where the letters and numbers in the image are carried out in several stages. The initial stage involves training using the EMNIST dataset to train the model to recognize general letter and digit characters before recognition in the CAPTCHA image. Furthermore, the process of recognizing letters and numbers in different CAPTCHA images is carried out to read the text contained in the CAPTCHA. The Convolutional Neural Network (CNN) model of the LeNet-5 method is used as a method for reading distorted letters and numbers in CAPTCHA with a high level of accuracy, achieving 88.56%.

Abstract

Economic growth is a key indicator of successful economic activities, with adequate crude oil availability playing a crucial role in supporting a country's economic development. This study aims to forecast Indonesian crude oil prices using an Autoregressive Integrated Moving Average (ARIMA)–Fuzzy Time Series (FTS) Cheng hybrid model. The data utilized consists of monthly Indonesian crude oil prices from January 2013 to April 2023 for training and from May 2023 to December 2024 for testing. The training data is modeled using ARIMA, and the residuals from the ARIMA model are subsequently analyzed using the FTS Cheng approach. The hybrid ARIMA-FTS Cheng forecast is generated by combining the predictions from both the ARIMA and FTS Cheng models. The results of the study show that the hybrid ARIMA–FTS Cheng model produced an MAPE of 7.46% on the training data and 4.57% on the testing data. Therefore, the ARIMA–FTS Cheng hybrid model is considered suitable for forecasting Indonesia's crude oil prices.

Abstract

Scalp dandruff is a common problem experienced by women and can cause discomfort and lower self-confidence. The large number of shampoo products on the market often makes it difficult for consumers to choose the product that best suits their scalp condition. This study aims to apply the MOORA (Multi-Objective Optimization on the Basis of Ratio Analysis) method to determine the best shampoo for women with dandruff. The problem faced is choosing an effective and safe shampoo for scalp dandruff, by considering various criteria such as price, active ingredients, and effectiveness in treating dandruff. This study uses predetermined criteria and calculates the weight of each criterion based on user preferences. Using the MOORA method, available shampoo alternatives are evaluated and ranked to find the optimal product. The results show that the MOORA method can provide objective and effective results in the decision-making process. With this system, it is hoped that consumers can more easily choose the appropriate shampoo, and assist manufacturers in improving product quality according to market needs. The research results show that the MOORA method can provide the right solution in choosing the best shampoo based on various factors, so that it can help consumers in making more informed and objective decisions.

Abstract

Harto Joyo Store faces challenges in inventory management due to manual recording processes. The main issue in managing sales data lies in the difficulty of grouping products based on sales patterns to support marketing strategies. This research aims to design and develop a web-based system capable of clustering products using the K-Means Clustering algorithm. The system was developed using the System Development Life Cycle (SDLC) with the Waterfall model, utilizing a dataset of 1,630 sales records from February 2023 to January 2024. The data was processed through the Knowledge Discovery in Databases (KDD) stages, which include Data Selection, Data Preprocessing, Data Transformation, Data Mining, and Knowledge Interpretation/Evaluation. The clustering process resulted in three data groups (Cluster 1 with 9 records, Cluster 2 with 191 records, and Cluster 3 with 28 records), with the number of clusters determined using the Elbow method. Cluster 1 represents best-selling products that require a high stock level, Cluster 2 includes low-demand products with minimal stock needs, and Cluster 3 consists of moderately-selling products that require a balanced inventory level. Evaluation using the Davies-Bouldin Index (DBI) yielded a DBI score of 0.356 for K=3, indicating optimal clustering results as it approaches zero. Initial testing shows that the system accurately classifies products into several sales clusters and can be used as a basis for business decision-making. This research contributes by providing a sales analysis system that can be integrated with the company’s information system. The analysis reveals that low-selling products dominate the data, suggesting that Harto Joyo Store should implement marketing strategies such as discounts or promotions to boost sales.

Abstract

Land certificate administration services at the ATR/BPN Mentawai Islands Office still face various obstacles, especially in terms of transparency and tracking of the application process which is carried out manually. This can cause uncertainty of information for the public. To overcome these problems, a web-based land certificate administration tracking information system was designed that can be accessed online. This system aims to make it easier for the public to monitor the progress of land certificate applications efficiently, quickly, and transparently.The system design was carried out using the System Development Life Cycle (SDLC) Waterfall model approach, which consists of the stages of needs analysis, design, implementation, testing, and maintenance. In system modeling, Unified Modeling Language (UML) tools were used, including use case diagrams, activity diagrams, class diagrams, and sequence diagrams. Sequence diagrams are used to describe the interactions between objects in the system, such as the flow of tracking certificate applications between users and the system.The system was developed using the PHP programming language on the server side and MariaDB as a database management system. The results of this study are in the form of a web application that can be used by the public and officers to track and manage land certificate applications digitally, effectively, and in a structured manner.

Abstract

Sundanese is one of the local languages taught at the elementary school level in West Java. Unfortunately, students’ enthusiasm and ability especially in understanding undak-usuk basa or speech level variations in Sundanese remain relatively low. This issue is generally caused by the lack of interactive teaching approaches and the absence of digital media that allow students to learn independently outside school hours. This condition poses a threat to the preservation of local languages among the younger generation. To address this problem, this study developed an Android-based Sundanese learning application using a gamification approach and the Extreme Programming (XP) method, with the goal of increasing students’ interest and understanding of undak-usuk basa independently. The development process involved five main stages: Planning, Design, Coding, Testing, and Release. Key features of the application include interactive quizzes, a coin-based point system, level progression, rewards, traditional Sundanese music, and a user interface designed to suit children. The application was developed using Android Studio with Kotlin and utilized Firebase Realtime Database for storage. To evaluate its effectiveness, pre-tests and post-tests were conducted on third-grade elementary students. The results showed an increase in the average score from 34 to 88 after using the application. These findings indicate that implementing gamification in an educational app based on the XP method can significantly enhance students’ interest and competence in learning the Sundanese language.

Abstract

The increasing intensity of internet usage in school environments demands optimal network management to ensure stable and high-quality connections. This study aims to evaluate the impact of bandwidth management implementation on the scalability of internet access within the Local Area Network (LAN) at SMKN 5 Seluma, Bengkulu Province. The research employed a descriptive quantitative method with an experimental approach, utilizing the Simple Queue feature on MikroTik devices. Data collection was conducted before and after the implementation, focusing on five key parameters: latency, bandwidth usage, packet loss, the ratio of active users to connection performance, and network availability. The test results showed significant improvements, including a reduction in latency from 144 ms to 52 ms, a decrease in packet loss from 2.58% to 0.5%, and an increase in availability from 94.5% to 99.48%. Statistical testing using the paired t-test confirmed that the differences were significant (p < 0.05). Therefore, the implementation of bandwidth management using the Simple Queue feature has proven effective in improving network efficiency and stability, even under high traffic conditions.
