Abstract

Purwakarta Regency has a variety of interesting tourist destinations, but the large number of choices often makes it difficult for tourists to determine the location that suits their preferences. This research aims to build a web-based decision support system (SPK) with the Complex Proportional Assessment (COPRAS) method to help select the best tourist destinations. The research methods include problem identification, literature study, data collection, implementation of the COPRAS method, and system testing. The criteria used in the evaluation process include cost, distance, tourist facilities, operating hours, accessibility, and reviews of digital maps. The results of the implementation of the COPRAS method show that Panenjoan Village is the destination with the highest ranking with a value of 1,000. This system can make it easier for tourists to choose a destination that suits their needs

Abstract

Batik merupakan kerajinan tradisional Indonesia yang memiliki nilai seni tinggi dan telah diakui sebagai warisan budaya dunia oleh UNESCO pada 2 Oktober 2009. Namun, pengetahuan tentang identifikasi motif batik umumnya hanya dimiliki oleh mereka yang memiliki keahlian khusus, seperti pengrajin batik. Penelitian ini bertujuan untuk mengembangkan aplikasi berbasis Streamlit yang mampu mengklasifikasikan motif batik menggunakan metode Convolutional Neural Network (CNN) dengan arsitektur ResNet-50 untuk dapat menjadi solusi dalam mengenalkan batik secara lebih luas kepada masyarakat, baik sebagai media edukasi maupun sebagai alat bantu bagi industri kreatif. Penelitian ini menggunakan metodologi CRISP-DM (Cross-Industry Standard Process for Data Mining) yang mencakup tahapan Business Understanding, Data Understanding, Data Preparation, Modeling, Evaluation, dan Deployment. Model dilatih selama 21 epoch, dengan hasil akurasi pelatihan sebesar 99,31%, akurasi validasi 94,37%, loss pelatihan 2,4%, dan loss validasi 22,25%. Dalam evaluasi menggunakan 140 sampel citra batik, model mencapai akurasi 89,285%. Hasil ini menunjukkan bahwa aplikasi yang dikembangkan berhasil dalam mengklasifikasikan motif batik menggunakan CNN.

Abstract

Environmental management in Cluster Cahaya Mekar Wangi is still manual, utilizing WhatsApp and Excel for dues recording, financial reports, and security tracking, which often results in data errors and low transparency. This study developed SIMLING, an Android-based application, to digitalize and integrate these processes into a unified system. Built using the Waterfall model with Kotlin (frontend), Golang (backend), and MySQL in Docker (database), SIMLING offers real-time payment recording with receipt uploads, automated validations, transparent reports, QR-based security monitoring, and centralized notifications. The implementation shows SIMLING streamlines administrative tasks, improves transaction validation, and enhances security monitoring, while providing residents with easier payments and clear financial information. This supports smarter, more structured, and sustainable community management.
