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

This study designs and develops an Application Android-based Geographic Information System (GIS) to assist residents of Purwakarta Regency in locating the nearest BPJS-affiliated healthcare facilities, addressing the limitations of distance information and mapping on the Health Office’s website. To compute distances, the application utilizes the Haversine Formula based on the user’s coordinates. It is developed using Flutter for the Android application and Laravel for the web-based admin system, following the Extreme Programming (XP) methodology. Blackbox Testing is used to ensure system functionality. As a result, the application can display a list and geographic locations of healthcare facilities along with the distance from the user. The application is expected to provide easier access to healthcare information and enhance the quality of health services in Purwakarta Regency.

Abstract

UMKM Bolu Ara is a micro business engaged in the production of cakes and sponges, which still uses manual methods in recording and managing orders via WhatsApp. This system causes various obstacles such as delays in payment verification, order recording errors, and difficulties in data management. To overcome these problems, the design and development of e-commerce websites using the Extreme Programming (XP) method was carried out. The XP method was chosen because it is iterative and flexible, with stages of planning, design, coding, and testing. The tools used include the CodeIgniter 3 framework, PHP programming language, MySQL database, and Visual Studio Code editor, with XAMPP support as a local server. Testing is done using the Black Box Testing method to ensure system functionality in accordance with user needs. The development results show that the e-commerce website built is able to make the process of recording and managing orders more structured, and provide convenience for users in making transactions independently. This system also supports managers in recording data and reports better.
