However, tourists often seek recommendations that align with their preferences. To address this need, a tourist destination recommendation application for the Lake Toba area has been developed using the Multi-Objective Optimization based on the Ratio Analysis (MOORA) method, incorporating Rank Order Centroid (ROC) weighting. This application aims to simplify the process for tourists to find appealing destinations based on their criteria. It provides optimal recommendations according to various factors, including type of tourism, region, ratings, ticket prices, operational days, and hours. The application features data on 123 tourist attractions. The resulting application is a mobile-based platform developed using API, PHP, and cross-platform technology, specifically Flutter. Thorough testing has been conducted, including system testing, user testing, and data management accuracy testing. The system testing revealed that the application operates smoothly without errors and that all functionalities perform as intended. User testing involved distributing questionnaires to 625 respondents who had used the application, comprising 144 individuals from North Sumatra (69.2%) and 65 from outside the region (30.8%). The feedback was overwhelmingly positive, with 94.2% of respondents finding the application easy to use, 94.1% satisfied that the recommendations met their needs, 83.2% deeming the design attractive, and 95.5% confirming that the information about each tourist destination was clear. Furthermore, 94.7% of users, both from within and outside North Sumatra, reported understanding the application flow, and 94.4% expressed their intention to use the app as a guide for visiting tourist sites in North Sumatra. The data management accuracy test indicated a strong correlation between manual calculations and the application's data handling capabilities for adding, modifying, and deleting tourism data. This recommendation application highlights tourism around Lake Toba, making its potential and local wisdom more appealing to new visitors.

Abstract

This research shows the effect of oil mixture and temperature on breakdown voltage. Palm oil is combined with diala-b oil in various mix ratios and various temperatures. Test results on the sample, as the concentration of the mixture of diala-b oil increases, the breakdown voltage value also increases. The breakdown voltage values of all oil mixture samples that have gone through the treatment process have met the IEC standard No. 56 of 1991 with results that are classified as above the standard (standard ≥ 30kV/2.5mm). Breakdown voltage values for the composition of 100% diala-b oil, 100% palm oil, and a mixture of 50% diala-b oil: 50% palm oil at 60 °C, 70 °C, 80 °C, 90 °C, and 100 °C is above the standard that is ≥ 30 kV. Water content and acidity affect the breakdown voltage value. Based on the results of breakdown voltage testing that has been done, palm oil can be used as an alternative to transformer oil.

Abstract

Caladium is a popular ornamental plant and has business potential. However, difficulties in recognizing the type of Caladium often occur because of the similarities in shape, pattern, and color of the leaves between the different kinds of Caladium. To overcome this problem, research will use machine learning with the Convolutional Neural Network (CNN) algorithm to build a mobile application that can accurately classify four types of Caladiums. The data set used is 1200 data with four classes; each class has 300 data. The best model is found with the parameter epoch 100, learning rate 0.001, and batch size 64. The model is then implemented in a mobile application with two menus, "Take a photo" and "Choose an image," which will display the classification output and confidence values of the four types of Caladiums. Testing with 30 test data per class achieves 0.975 accuracy on both menus. On the “Take a photo” menu, precision is 0.974, recall is 0.9725, and f1-score is 0.965. Meanwhile, on the “Choose an image” menu a precision and recall value is 0.975, and f1-score value of 0.97.

Abstract

The aim of this research is to analyze the regional autonomy policy to improve the quality of public service in the Islamic perspective. Regional autonomy as a policy of decentralization gives authority to local governments to self-regulate regional affairs, with the aim of improving the efficiency and effectiveness of service to local communities. In Islamic terms, the concept of leadership and public service is strongly based on the principles of justice, trust, and the well-being of the people (maslaha). This study uses a method of literature study used to examine articles published in scientific journals at a particular time to find out how Islamic principles can be applied in the context of regional autonomy policy in Indonesia. Research results show that the implementation of Islamic values in regional autonomy policies can improve the quality of public service by strengthening accountability, transparency, and public participation. Furthermore, the implementation of a policy based on Islamic doctrine can encourage the formation of a government that is more responsive and accountable to the needs and wishes of local communities. The study concludes that there is great potential for achieving better public service through the synergy of regional autonomy policies and Islamic principles.

Abstract

The farmer group in the Silaen sub-district which is located in Toba Regency is a farmer group where the majority of farmers are corn farmers. The general problems faced by this farmer group include the ineffectiveness of the harvest process where farmers have to peel and dry the corn before the corn is ground using a corn sheller machine. Therefore, this research was carried out in order to answer the problems faced by this farmer group. Where in this research we will design a machine for peeling and shelling corn, so that farmers will be more practical when carrying out the harvest process. In this research, the Axiomatic House of Quality (AHOQ) method was used by integrating it with the House of Quality (HOQ) and Axiomatic design (AD). Then you will get a design and specifications for a corn peeling and shelling machine that uses an oil-fueled engine.

Abstract

This research proposes a novel method for detecting artificial intelligence (AI)-generated essays by integrating the bidirectional encoder representations from transformers (BERT) model with particle swarm optimization (PSO). Unlike traditional approaches that rely on manual hyperparameter tuning, this study introduces a systematic optimization technique using PSO to improve BERT’s performance in identifying AI-generated content. The key problem addressed is the lack of effective, real-time detection systems that preserve academic integrity amidst rapid AI advancements. This optimization enhances the model’s detection accuracy and operational efficiency. The research dataset consisted of 46,246 essays, which, after data cleaning, were refined to 44,868. The model was then tested on 9,250 essays. Initial evaluations showed BERT's accuracy ranging from 83% to 94%. After being optimized with PSO, the model achieved an accuracy of 98%, an F1-score of 98.31%, precision of 97.75%, and recall of 98.87%. The model was deployed using a FastAPI-based web interface, enabling real-time detection and providing users with an efficient way to quickly verify text authenticity. This research contributes a scalable, automated solution for AI-generated text detection and offers promising implications for its application in various academic and digital content verification contexts.
