Abstract

Short-term Bitcoin price prediction is a crucial aspect of transaction decision-making, especially for investors. In this study, a Bidirectional Long Short-Term Memory (Bi-LSTM) model was developed for short-term Bitcoin price prediction. The Bidirectional LSTM is designed to capture temporal context in both directions, allowing the model to process information from past and future time steps simultaneously. The model was validated using real-world data, including Bitcoin stock price datasets. The results show that the model achieved high accuracy, with a Root Mean Square Error (RMSE) of 56.90 on the training data and 157.35 on the test data, along with a Mean Absolute Error (MAE) of 366.40 and 486.63, respectively. The Bidirectional Least Square Memory model accurately predicted Bitcoin prices over a specific time period. This application integrates the model into a web application, enabling users to obtain real-time Bitcoin price predictions through a user-friendly interface.

Abstract

Tenun Ikat Troso atau Kain Ikat Troso adalah kriya tenun Jepara tepatnya dari Desa Troso. Tenun Ikat Troso berupa kain yang ditenun dari helaian benang pakan atau benang lungsin yang sebelumnya diikat dan dicelupkan ke dalam zat pewarna alami. Di Sentra Tenun Ikat ini pengunjung tidak hanya berwisata atau sekedar membeli sepotong kain saja, tetapi juga dapat mempelajari Kain-kain juga, sayangnya informasi yang ada hanya melalui deskripsi yang diberikan oleh penjaga toko yang sedang menjaga. Sayangnya kalau pengunjung toko tiba-tiba melonjak, penjaga kewalahan kalau dicecar pertanyaan oleh banyak pengunjung. Oleh sebab itu dengan dibuatkannya aplikasi ini diharapkan nantinya akan mempermudahkan tugas penjaga yang sedang dalam bertugas. Metode yang digunakan dalam perancangan ini menggunakan metode prototype, yang dapat digunakan untuk menghubungkan ketidakpahaman client. Pengunjung bisa melakukan scan ke Qr code yang sudah disediakan dengan menggunakan smartphone masing-masing dan bisa mendapatkan informasi tentang deskripsi kain. Penelitian ini menghasilkan sebuah Sistem Informasi Identifikasi Kain Tenun Berbasis Mobile yang menyediakan layanan berupa informasi jenis dan motif kain yang jelas di Kawasan Industri Tenun Ikat Jepara.MOBILE-BASED WOVEN FABRIC IDENTIFICATION INFORMATION SYSTEM IN THE JEPARA IKATE WEANING INDUSTRIAL AREAIkat Weaving from Troso or Troso Ikat Fabric is a weaving craft from Jepara, precisely from Troso Village. Troso Ikat is a fabric woven from strands of weft yarn or lungsin yarn that have been tied and dipped into natural dyes. In this Ikat Weaving Center, visitors can not only enjoy tourism or simply buy a piece of fabric but also learn about the fabrics. Unfortunately, the available information is only provided through descriptions given by the shopkeepers on duty. Regrettably, when the number of shop visitors suddenly increases, the shopkeepers are overwhelmed with questions from many visitors. Therefore, with the creation of this application, it is hoped that it will facilitate the duties of the shopkeepers on duty. The method used in this design uses the prototype method, which can be used to bridge the gap of understanding with the clients. Visitors can scan the provided QR code using their smartphones and get information about the fabric's description. This research resulted in a Mobile-Based Woven Fabric Identification Information System that provides services in the form of clear information about the types and patterns of fabric in the Jepara Ikat Weaving Industrial Area.

Abstract

Located in Kembang Subdistrict, Jepara Regency, Dudakawu Village possesses significant economic potential. However, its development is hindered by challenges such as inadequate entrepreneurial skills, ineffective marketing strategies, and limited access to digital technology. To overcome these issues, the PPK Ormawa Team of the Student Executive Board from the Faculty of Science and Technology at Unisnu Jepara initiated the "Entrepreneurial Village" program as a community service project. The program aims to improve entrepreneurial skills, enhance the competitiveness of local products, and broaden market access through digital transformation. This initiative utilized several strategies, including entrepreneurship workshops, the establishment of UMKM (Micro, Small, and Medium Enterprises) groups, product branding training, digital marketing education, and the development of innovative products. Activities were carried out through a collaborative approach involving academics, students, local authorities, and the community. Periodic evaluations were conducted using pre- and post-activity questionnaires, interviews, and direct observations to measure the program’s effectiveness in enhancing community skills and business activities. The findings reveal that more than 70% of participants improved their knowledge of entrepreneurship and digital marketing. The UMKM community established during the program served as a collaborative platform for local entrepreneurs, while products such as banana stem chips and the village’s specialty coffee gained added value and greater competitiveness in regional markets through branding and digital marketing efforts. This program has contributed significantly to sustainable, community-driven economic empowerment and offers a replicable model for other villages.
