Abstract

Cocoa is one of Indonesia’s leading agricultural commodities and plays a strategic role in increasing national foreign exchange earnings. However, the low quality of Indonesian cocoa beans remains a major obstacle in penetrating the export market. This issue is largely caused by post-harvest drying processes that still rely on traditional sun-drying methods. Dependence on weather conditions often results in cocoa beans failing to reach the ideal moisture content (6–8%), making them susceptible to mold growth, deterioration, and reduced quality. These conditions ultimately lower the market value and competitiveness of Indonesian cocoa in the global market.This study aims to develop a direct-type active solar dryer technology powered by solar energy to improve drying efficiency and preserve the quality of cocoa beans. The system is designed using a combination of solar panels, heating elements, and exhaust fans controlled to regulate temperature, humidity, and airflow optimally throughout the drying process. The methodology includes design engineering, thermal simulation, and experimental testing to determine the best operating conditions that ensure fast drying, energy efficiency, and maintained physical and chemical quality of the cocoa beans. This research is expected to serve as an innovative step in the application of renewable energy in the agricultural sector, contributing to improved productivity and sustainable competitiveness for Indonesian cocoa farmers.

Abstract

Braille digitization plays an important role in improving access to written information for visually impaired individuals. However, automatic recognition of Braille text remains challenging due to the small size, dense spatial arrangement, and subtle variations of Braille dot patterns. This study proposes a syllable-based Braille cell detection and recognition framework using a customized Faster R-CNN architecture. The system employs a Region Proposal Network (RPN) to localize individual Braille cells, followed by an AlexNet-based classifica-tion network to recognize syllable-level patterns. The proposed method is evaluated on a syllable-level Braille dataset covering 50 syllable classes, and a two-stage training strategy is adopted to improve bounding box localization accuracy. Experimental results show stable training convergence and consistent classification performance across syllable categories. Confusion matrix analysis indicates that most misclassifications occur among syllables with visually similar dot configurations. Despite sensitivity to variations in physical Braille quality, the proposed framework indicates potential applicability in accessibility-oriented Braille digitization systems

Abstract

Advances in information technology have led government agencies to adopt digital changes in administrative management, including document archiving. Manual archive management is still widely used and causes various problems, such as difficulty in searching for documents, the risk of archive destruction, and a lack of work efficiency. The Health Resources Division of the Pati District Health Office has a high volume of documents, requiring an integrated, digital-based archiving system. This study aims to design and develop a Web-Based Document Archiving Information System to increase the effectiveness of archive management, speed up the document search process, and support orderly administration. The system was developed using the Waterfall method, which includes the stages of requirements, analysis, design, implementation, testing, and maintenance. The system was refined using the PHP programming language and a database as a centralized archive storage medium. The main features of the system include user authentication, document uploading by category, and document management in the form of viewing, downloading, renaming, and deleting documents. System testing was conducted using the Black Box method on 26 functional components, and the test results indicated that all system functions worked well as required. Thus the developed information system is capable of improving archive management capabilities and supporting the improvement of administrative service quality in the Health Resources Division of the Pati District Health Office.
