Abstract

Rice is a strategic commodity in Indonesia, yet its productivity is often threatened by leaf diseases such as Bacterial Leaf Blight, Brown Spot, Narrow Brown Spot, and Tungro. Conventional identification conducted by farmers is subjective and may delay proper treatment. This study implements transfer learning using the MobileNetV2 architecture for rice leaf disease classification. The dataset was collected directly from rice fields in OKU Timur, South Sumatra, consisting of five classes (Bacterial Leaf Blight, Brown Spot, Healthy, Narrow Brown Spot, and Tungro), each containing 300 images except Narrow Brown Spot, which was balanced through light augmentation. All images underwent cropping, resizing to 224×224 pixels, and normalization before being split into training, validation, and testing sets. The proposed model achieved 99.11% validation accuracy and 100% testing accuracy, with near-perfect precision, recall, and f1-score. The model was then deployed into a user-friendly web application using Streamlit, enabling farmers to upload rice leaf images for instant classification and recommended treatments. These findings demonstrate that MobileNetV2 with transfer learning provides accurate early detection of rice leaf diseases and supports better decision-making in rice cultivation.

Abstract

This study aims to develop a web-based information system for internship registration and report management at the Palembang City Communication and Informatics Office. Previous studies have developed internship information systems that generally focus on online registration, document submission, certificate generation, academic administration, and notification features. However, existing systems typically do not include secure account verification, structured daily logbook monitoring, or integrated role-based data management tailored for government institutions. These limitations create a gap that this study addresses by developing a more comprehensive and transparent internship management solution. A descriptive qualitative approach was used through interviews and observations, and a prototyping model guided the system development process. The system was built using Next.js, Express.js, MongoDB, JSON Web Token (JWT), Nodemailer, and Tailwind CSS, with features such as online registration, document upload, account verification, daily logbook submission, final report upload, and role-based access for admins and supervisors. Implementation results show improvements in administrative speed, communication, data accuracy, and transparency compared to manual processes. Overall, the system supports a more modern, efficient, and structured internship management process within government institutions.

Abstract

This research analyzes the distribution of public transport services from AKDP and AKDK units in 40 sub-districts in Bogor Regency, an area with rapid population growth that faces congestion due to dependence on private vehicles. The main problem is that service gaps have not been mapped quantitatively, so the aim of this research is to apply clustering techniques to identify underserved areas and provide an objective basis for data-based policy recommendations. The proposed method is a quantitative approach using the K-Means Clustering algorithm on secondary datasets from the Department of Transportation with three main features: number of licensed fleets, number of unlicensed fleets, and total fleet. The main findings succeeded in classifying sub-districts into three clusters, Cluster 0 (established services), Cluster 1 (static growth), and Cluster 2 (significant service gaps dominated by informal fleets). In conclusion, this research proves the existence of significant service disparities, and shows that the clustering method is effective in mapping priority zones for more equitable transportation policy interventions.

Abstract

SIPPMASBIMA UWHS stands for Sistem Informasi Internal Penelitian Pengabdian BIMA Internal UWHS (Internal Information System for Research and Community Service of UWHS), which is designed as a system architecture for uploading research and community service data. The urgency of this research lies in the fact that the previous system used for managing research and community service data at the UWHS LPPM had limitations in data uploading, and lecturers were not accustomed to the system used by the Ministry of Education, Culture, Research, and Technology (Kemendikbudristek). Therefore, the objective of this research is to develop a new system that is more integrated and user-friendly, with an interface and methods resembling the BIMA system of Kemendikbudristek, to support lecturers in adapting their data input practices in accordance with the ministry’s system. The method applied is Agile Development, ensuring flexibility in feature development based on user needs. The targeted outcomes include an information system, a journal publication (at least Sinta 4), and a system prototype.

Abstract

Digital watermarking is important for copyright protection, but challenges remain in maintaining a balance between imperceptibility and robustness. This study evaluated Discrete Cosine Transform (DCT)-based watermarking on JPEG images by inserting binary watermarks at the intermediate frequency coefficient of the DCT block 8×8. The method was tested against JPEG compression, Gaussian noise, Gaussian blur, and Salt & Pepper noise to assess the visual quality and durability of the watermark. The results show high visual quality with an average PSNR of 39.99 dB and a SSIM of 0.96, so the watermark is almost imperceptible. Robustness testing yielded a BER of 1.5% on Gaussian noise, 5.2% on JPEG compression, and 8.2% on Salt & Pepper noise. These findings prove that the DCT method is able to maintain image quality and maintain a watermark on most interferences, despite degrading performance in impulse attacks and aggressive compression. In practical terms, this approach can be applied to digital image protection systems and forms the basis for the development of more robust hybrid or adaptive methods in the future.
