Abstract

Diffusion-advection is the process of transportation of matter from one part of a system to another as a result of random molecular motions involving fluid transport processes in the form of mean flow or currents which are driven by gravity or pressure forces and in the form of horizontal motions. Mathematically, diffusion-advection equation can be written as where is concentration of material in the fluid, stands for the advection velocity, and for diffusion coefficient. In this paper, a solution is sought by using the Green’s function concept. The general solution for Green’s function that can be solved in two parts, namely, the principal solution and the regular solution. The principal solution is obtained by applying the Fourier transform to the variable which is denoted by and then calculate the inverse of its transform. A regular solution is obtained based on an inspection approach that is designed on a negative heat source.

Abstract

Kemajuan teknologi yang pesat telah memberikan pengaruh besar terhadap cara usaha mikro, kecil, dan menengah (UMKM) beroperasi dan bersaing di dunia bisnis. Penelitian ini membahas penerapan website e-commerce menggunakan platform Odoo.com pada Captain Distro, sebuah toko fashion di Kota Sorong, Papua Barat Daya. Melalui wawancara, observasi langsung, dan studi pustaka, penelitian ini mengidentifikasi tantangan utama yang dihadapi usaha, yaitu masih mengandalkan proses penjualan dan administrasi secara manual. Pengembangan sistem informasi digital berupa website diharapkan dapat mempermudah promosi produk, memperluas jangkauan pasar, serta meningkatkan kualitas pelayanan kepada pelanggan. Hasil pengabdian kepada masyarakat menunjukkan bahwa website membantu memperlancar proses penjualan, pengelolaan stok, dan administrasi, sehingga meningkatkan efisiensi dan daya saing usaha. Inovasi ini membuktikan pentingnya transformasi digital bagi UMKM agar dapat bertahan dan berkembang di pasar yang semakin kompetitif. Sosialisasi literasi hukum digital juga menjadi hal penting yang perlu dimiliki oleh pelaku UMKM dalam menjalankan usahanya secara daring. Pemahaman terhadap regulasi seperti perlindungan data pribadi, transaksi elektronik, dan hak kekayaan intelektual menjadi kunci untuk menciptakan ekosistem digital yang aman dan terpercaya.
