Abstract

This study aims to optimize the search for nearby coffee shops using the Haversine algorithm in a mobile recommendation system based on Location-Based Filtering (LBF). The system was developed by utilizing GPS, OpenStreetMap, and Firebase to provide real-time coffee shop recommendations according to the user’s location. The research methodology consisted of problem identification, coffee shop location data collection, implementation of the Haversine algorithm for geographic distance calculation, application of the Location-Based Filtering method to sort recommendations based on the nearest distance, and system evaluation using User Acceptance Testing (UAT) and distance accuracy comparison with Google Maps. The results showed that the system was able to calculate location distances with an average accuracy rate of 98.86% compared to Google Maps, with a distance difference ranging only from 0.03 to 0.05 km. In addition, the system successfully provided fast and relevant coffee shop recommendations based on the user’s real-time location. These findings indicate that the combination of the Haversine algorithm and Location-Based Filtering method is effective for implementation in a mobile-based coffee shop recommendation system to improve location search efficiency in real time.

Abstract

Wood type classification in the timber industry is frequently hindered by the high visual similarity of grain patterns, a structural challenge that is particularly pronounced with small-scale datasets. This study systematically resolves this fine-grained visual ambiguity by developing a rigorously optimized InceptionV3 framework. Initial baseline evaluations conducted on a dataset of 800 images encompassing four wood species, namely Pterospermum javanicum (Bayur), Magnolia champaca (Cempaka), Tectona grandis (Jati), and Melia azedarach (Mindi), revealed that a standard ResNet50 architecture experienced a severe performance degradation, generating a random guess accuracy of merely 25 percent. Addressing this severe architectural inadequacy, the proposed InceptionV3 model integrates highly targeted spatial augmentations, a Dropout rate of 0.6, and L2 regularization. Furthermore, the optimization strategy deploys Stochastic Gradient Descent with Nesterov momentum and Label Smoothing to explicitly mitigate intra-class visual similarities. Consequently, the proposed framework achieved a robust overall accuracy of 89 percent, surpassing the baseline by a substantial 64 percent, alongside a macro-averaged F1 Score of 0.89. These empirical findings substantiate that specific architectural fine-tuning and advanced stochastic regularization are highly essential for capturing subtle wood-grain patterns, thereby offering a highly reliable, automated quality-control solution for the timber industry.

Abstract

This research aims to implement the Promethee method (Preference Ranking Organization Method for Enrichment Evaluation) in recommending appropriate skincare products based on facial skin type. With so many skincare products on the market, consumers may have difficulty choosing the right product. The Promethee method helps make multi-criteria decisions by considering various relevant factors such as skin type, price, user ratings, product quality, and price suitability based on the preferences of people who have used skincare products before as a reference in recommending skincare products. Recommendations are made based on data from the preferences of students who have used skincare products and provide an assessment of the products they have used. Researchers used the Promethee method as research to see how effective its use is in providing skincare product recommendations. The data used as a basis for manual calculations uses 10 data points for normal skin types. With the highest net flow value for normal skin types of 3.44444444 for Wardah Lightning and Ponds Men products. The highest net flow value for combination skin type is 24.250000, net flow for oily skin type is 14.222222, net flow for sensitive skin type is 14.722222, and net flow for dry skin type is 8.166667. The research results show that the Promethee method can provide appropriate recommendations regarding the selection of skincare products based on facial skin type.

Abstract

Along Malioboro street, there are electric scooter rental services that make it easier for tourists to explore the surrounding area. By renting an electric scooter, visitors can enjoy the nighttime atmosphere with a gentle breeze and a beautiful view of the city lights. This service is in high demand, especially by young people, as it provides a unique and fun traveling experience. Although the scooter rental service in Malioboro provides convenience for tourists, there are some problems faced in its implementation. One of the main problems is the absence of a dedicated platform for scooter rental. Travelers can only rent directly, so there is often a scramble.

Abstract

The wedding industry in Indonesia has undergone a significant transformation thanks to technological advancements and changing consumer behavior. Today, brides-to-be are increasingly utilizing digital platforms to search and book wedding services. Many vendors still manage the booking system conventionally. The booking system at vendors still uses regular telephone calls so there are often errors in recording bookings because the vendors often forget to record the booking schedule in the ledger. Promotional activities are also still very limited. This research aims to develop a mobile web-based application that facilitates wedding vendors in offering their services and products more efficiently. This application is designed to overcome various challenges faced by vendors, such as difficulties in promoting vendors to prospective brides, managing bookings, communicating with clients, and improving operational efficiency to achieve client satisfaction with the services provided. The application development involved collecting wedding package data, product data (such as physical souvenirs and invitations), system design, technology selection, and implementation and evaluation strategies. The technologies used include React JS for web application development and React Native for mobile applications, both using the JavaScript programming language. The database uses MongoDB, with the support of platforms such as Stripe as a payment gateway. The software development method applied is Agile, to ensure flexibility and responsiveness to user needs. The interim result of this research is an application that provides a source of information for prospective brides related to vendors of wedding organizer products and services with a wide scope. In addition, the Moore App has been tested by 30 respondents with an average success rate of 100%, indicating that all features function properly according to user needs and established specifications.
