This study aims to analyze the digital marketing strategies implemented by clothing stores in the Telang area from a sharia economic perspective. In the digital era, business actors are required to adapt to technology, including in terms of promotion and marketing. The approach used in this study is descriptive qualitative, with data collection through observation, interviews, and documentation. The results of the study show that most business actors have utilized social media such as WhatsApp, Instagram, and Facebook Marketplace to market their products. The strategies implemented are mostly in line with the principles of sharia economics such as honesty (?idq), openness (tabligh), and amanah. However, some practices that are not in accordance with sharia are still found, such as the use of photos that do not match the original product (gharar) and excessive promotion (tadlis). The main inhibiting factors in the implementation of sharia digital strategies are limited digital literacy and infrastructure. Therefore, ongoing assistance and training in sharia-based digital marketing are needed to improve understanding and business practices in accordance with Islamic values.

This study investigates the solutions of electrical current in linear circuit systems using two numerical methods implemented in MATLAB: the Matrix Inverse Method and the Gauss-Jordan Elimination Method. The objective is to analyze the effectiveness, accuracy, and computational efficiency of both techniques in solving systems of linear equations derived from Kirchhoff's laws. Several circuit models with varying levels of complexity are tested to compare results obtained from each method. The findings indicate that both methods yield consistent solutions, although differences in computational steps and processing time are observed. This research highlights the practicality of MATLAB as a powerful tool for electrical circuit analysis and provides insights into the selection of appropriate numerical methods for solving engineering problems.

Kebutuhan air bersih yang terus meningkat dan cakupan pelayanan yang kurang tersebar ke berbagai daerah di Kabupaten Jember menjadi latar belakang adanya perencanaan ini. Kecamatan Sukowono masih belum terlayani ada jaringan perpipaan dari PDAM. Perencanaan ini bertujuan untuk merencanakan sistem distribusi air minum di Kecamatan Sukowono pada 5 Desa Prioritas. Fokus penelitian ini adalah terhadap pembentukan District Meter Area (DMA) di Desa Sukowono karena kepadatan penduduk yang tinggi. DMA dipilih dikarenakan sudah efektif dan terbukti dalam mengoptimalkan jaringan yang kecil terjadi kebocoran air. Hasil perencanaan penelitian ini berupa jaringan perpipaan SPAM dengan sumber air gayam debit 75 l/detik menggunakan sistem bercabang, pengaliran secara pompa pada elevasi tinggi dan gravitasi pada elevasi rendah, peta pembagian blok pelayanan dan DMA serta hasil analisis hidrolis menggunakan EPANET. Dari hasil,analisis. EPANET diperoleh tekanan terendah 14.76, tekanan tertinggi yaitu 69,18 m. Pada jam puncak tekanan terendah yaitu 11,43 m dan tekanan tertinggi pada 62,58 m. Kecepatan terendah yaitu 0,30 m/s dan tertinggi 0,71 m/s.  Sedangkan untuk kecepatan pada jam puncak terendah 0,58 m/s dan tertinggi 1,37 m/s. Pompa yang digunakan yaitu jenis submersible tipe inline single stage pumps. Pipa dalam perencanaan ini menggunakan rucika black dengan diameter terkecil 32 mm dan terbesar 500 mm.
