Abstract

Registration of proposal seminars at the Sheikh Abdul Halim Hasan Binjai Institute is still done manually, which causes problems such as late information, errors in data recording, and lack of efficiency in administrative management. The institute currently has approximately 1,200 active students, with an average of 150–200 students submitting seminar proposals each semester. This increasing number of participants makes the manual system even more burdensome and prone to errors. To overcome these problems, a website-based proposal seminar registration system was implemented. This system is designed to make it easier for students to register, as well as help the administration in managing the data of seminar participants in a more effective and structured manner. The system development uses the PHP programming language with a MySQL database and the waterfall development method as a systematic approach in the implementation process. The results of the implementation show that the system is able to improve the efficiency of the registration process, minimize data errors, and provide real-time information for students and supervisors. With this system, it is expected that the proposal seminar administration process will become more organized and transparent.

Abstract

Packaging design plays an essential role in shaping consumers’ first impressions of a product, particularly in the batik industry, where cultural meaning and visual identity are deeply intertwined. This study aims to explore how a Convolutional Neural Network (CNN) can help identify consumer preferences toward various batik packaging designs. The dataset consists of real packaging from local SMEs as well as prototype designs created specifically for this research, incorporating variations in motifs, colors, and structural formats. All images were standardized and normalized to ensure consistency before being processed by the CNN model. The architecture consists of several convolutional layers, pooling layers, and fully connected layers, with dropout applied to reduce overfitting. Model training was conducted using the Adam optimizer and the sparse categorical cross-entropy loss function. The results demonstrate that the model achieved a testing accuracy of 92.51%. Stable performance across precision, recall, and F1-score indicates that the CNN effectively captures visual patterns associated with consumer appeal. These findings highlight the potential for batik SMEs to utilize deep learning as a decision-support tool, enabling them to design packaging that is more appealing, relevant, and aligned with contemporary consumer preferences.

Abstract

Air pollution in DKI Jakarta is an important issue and has a negative impact on public health. This study applies the naive Bayes algorithm to classify air quality, Utilizing the SMOTE technique effectively addresses the issue of data imbalance. The data analyzed came from air pollution index data from 2022 to 2024, taken from five air monitoring stations in Jakarta. The analysis process was carried out following the CRISP-DM stages, starting from understanding the problem to evaluating the model. The results showed that SMOTE succeeded in increasing prediction accuracy in fewer classes. Without SMOTE, the model accuracy reached 90% but appeared biased towards fewer classes, with a recall value of only 0.75 and a precision of 0.62. While SMOTE, the model accuracy became 88%, with a precision value of 0.86, recall 0.87, and f1-score 0.87, which showed more balanced results across classes.

Abstract

 In In the digital age, the use of information technology in public services, including population administration, is crucial. To facilitate access to online population services, the Population and Civil Registration Office of Central Lombok Regency provides the SEMAIK website. Nonetheless, several issues persist, particularly in system quality and service quality. System performance often becomes unstable, with the website slowing down when many users submit service requests simultaneously, while service responsiveness is also frequently delayed. These issues highlight the need for a more comprehensive evaluation of the platform. This study aims to quantitatively assess the effectiveness of the SEMAIK website using the DeLone and McLean Information System Success Model. Data were collected through questionnaires distributed to 126 respondents and analyzed using the SEM-PLS approach. The findings indicate that information quality positively influences system use but does not significantly affect user satisfaction. Meanwhile, service quality, system quality, and system use all show positive effects on user satisfaction. Additionally, although system use does not significantly contribute to net benefits, user satisfaction demonstrates a strong positive effect on net benefits. The model also meets the criteria for good model fit based on the goodness-of-fit assessment. However, the results suggest that aspects related to information quality and system use require improvement, as their effects on user satisfaction and net benefits are not yet optimal. These findings provide concrete recommendations for enhancing the SEMAIK website to ensure more effective and reliable digital public services.

Abstract

Vehicular Ad-hoc Networks (VANETs) are dynamic wireless systems enabling vehicles to exchange data such as speed, location, and direction. A core component in VANETs is the routing protocol, with Ad-hoc On-Demand Distance Vector (AODV) being widely used. However, AODV struggles in highly dynamic environments, leading to reduced performance in throughput and end-to-end delay. This study proposes an improved AODV protocol using the Learning Automata approach (LA-AODV), which enhances relay node selection for better routing efficiency. The performance of LA-AODV is evaluated against standard AODV using NS-3 and SUMO simulations, focusing on key Quality of Service (QoS) metrics: throughput, packet delivery ratio, packet loss, and end-to-end delay. Simulation results show that LA-AODV significantly increases throughput (up to 90.84 Kbps) and reduces end-to-end delay by 20–35%, while lowering communication complexity (15–25% fewer Flow IDs). However, LA-AODV suffers from higher packet loss (up to 62%) and lower delivery ratios (37–92%) compared to AODV. This performance trade-off highlights LA-AODV's improved data efficiency at the cost of reliability. To mitigate delivery issues, solutions such as buffer tuning, adaptive queuing, or hybrid protocols are suggested. Future research should address these challenges and examine LA-AODV's scalability in larger VANET deployments.
