Abstract

Schistosomiasis caused by the Schistosoma japonicum worm is a significant health problem in Indonesia, especially in endemic areas such as the Napu Plateau and Bada Plateau. The main problem in controlling this disease is the difficulty in rapid and accurate identification of Oncomelania hupensis lindoensis snails as intermediate hosts of the parasite. This research aims to develop an artificial intelligence-based system that can efficiently identify the snail species. The stages of this research include collecting snail image data from the Central Sulawesi Provincial Health Office, consisting of 2100 images covering seven snail species, then processed through preprocessing and augmentation stages. The model applied was EfficientNet-B0. The results showed that the EfficientNet-B0 model achieved 98.80% training accuracy and 98.33% validation accuracy. Confusion matrix testing showed good performance, with an accuracy of 98% and for the species Oncomelania hupensis lindoensis had a recall of 93%, precision of 100%, F1-score of 97%, and the resulting AUC value of 99.7%. This research successfully developed an efficient identification system, which is expected to help health surveillance personnel in accelerating the identification process of schistosomiasis intermediate hosts.

Abstract

This research focuses on the problem of PT Anugrah Wina Sentosa, which is a producer of bottled drinking water in Central Sulawesi. The company faces challenges in organizing and improving the efficiency of the distribution of bottled drinking water products. Problems include distribution management that has not been optimized and distribution arrangements at various outlets that have not been mapped. Based on this problem, researcher develop a web-based distribution system with the Distribution Requirement Planning (DRP) algorithm and Trend Moment Algorithm to see the results of sales and distribution predictions. The designed application can carry out data processing, Distribution Requirement Planning processes, Trend moment processes, MAPE calculations, and sales predictions. The application development method uses the Waterfall method. The test results show that the system can manage input, edit, and delete data and run DRP calculations as a whole or per outlet. With an error value of 1.71%, the trend moment forecasting system proved to be very accurate in forecasting sales of drinking water products. Thus, the implementation of a web-based distribution system can improve production efficiency and facilitate stock management and distribution management at PT Anugrah Wina Sentosa. This research has several limitations that need to be considered, namely limited scope, limited data, limited generalization, limited affordability, and limited time.

Abstract

Introduction: Eye disease, especially in adolescents, has various symptoms. Currently, most adolescents pay little attention to the condition of the eyes. The assumption circulating in society is that the disease will heal on its own without the need for medical treatment. As a result, many adolescents experience delays in treatment. Method: This method is used because forward chaining uses a search value or reasoning that starts from facts to get conclusions from these facts to assume the degree of confidence of an expert. The data in this study are data on symptoms and eye types in adolescents aged 12-15 years obtained through interviews with experts at the Smec Palu eye clinic. This study uses 3 tests namely Alpha testing, beta testing, and accuracy testing. Results and Discussion: System testing is done through alpha testing, beta testing, and accuracy testing. Alpha testing shows that the system components function as expected. Beta testing uses a questionnaire that produces a percentage of 86% for System Quality, 86% for Information Quality, and 88% for User Satisfaction. Accuracy testing shows that the system has 100% accuracy because all test data matches the results of expert analysis. This shows that the system has very good accuracy. Conclusion: Expert system testing to diagnose eye diseases in adolescents aged 12-15 years with the forward chaining method shows positive results. Alpha testing ensures that all features function properly, while beta testing gives a score of 86% for System and Information Quality, and 88% for User Satisfaction. Accuracy testing showed 100% results. This system is effective for diagnosing eye diseases based on symptoms.

Abstract

The increasing complexity of supply chains, driven by globalization and technological advancements, necessitates effective logistics collaboration, particularly for food SMEs in Indonesia. Despite its recognized benefits, many SMEs face fragmented supply chains, inefficient distribution networks, and resource limitations that hinder competitiveness. Addressing these challenges is crucial for improving supply chain resilience and efficiency. This research examines the influence of horizontal, vertical, and lateral logistics collaboration on the supply chain performance of food SMEs in Indonesia. Using a quantitative approach and Partial Least Squares Structural Equation Modeling (PLS-SEM), the study analyzes data from food SMEs in Palu, Indonesia. A purposive sampling technique was employed, targeting SME owners and managers involved in logistics collaboration, resulting in a final sample size of 92 respondents. The findings reveal that horizontal logistics collaboration has the most significant impact, enhancing efficiency and effectiveness through partnerships among SMEs and distributors. Vertical collaboration also demonstrates a strong influence, improving integration and synchronization between producers and distributors. However, lateral logistics collaboration does not exhibit a statistically significant effect, likely due to coordination challenges and a lack of resources. This research contributes to logistics literature by empirically validating the varying impacts of collaboration types on SMEs' supply chains in an emerging market. The findings highlight the superior role of horizontal partnerships and suggest fostering collaboration through digital platforms, training, and the adoption of technology. Future research should explore government policies, digitalization, and sustainability practices to develop comprehensive strategies for optimizing logistics collaboration among SMEs.
