Abstract

Udang vaname merupakan salah satu komoditas budidaya budidaya yang bernilai ekonomi tinggi dan banyak dibudidayakan di wilayah pesisir Indonesia, termasuk di Desa Pendowolimo, Kecamatan Karangbinayun, Kabupaten Lamongan. Namun, produktivitas panen seringkali tidak stabil karena faktor-faktor seperti perubahan iklim, kualitas air, dan terbatasnya penggunaan teknologi prediktif. Penelitian ini bertujuan untuk merancang dan membangun sistem prediksi panen udang vaname berbasis web menggunakan metode K-Nearest Neighbors (KNN). Metode KNN dipilih karena kemampuannya melakukan klasifikasi dan prediksi berdasarkan kedekatan data historis. Kumpulan data yang digunakan terdiri dari 150 catatan panen dengan variabel antara lain periode panen, luas tambak, jumlah tebar ("rean"), durasi tumbuh, dan jumlah pakan. Perhitungan dilakukan dengan menggunakan jarak Euclidean untuk menemukan tetangga terdekat K tersebut, dan hasil panen diprediksi dari nilai rata-rata tetangga tersebut. Untuk mengukur akurasi sistem, digunakan Mean Absolute Percentage Error (MAPE), menghasilkan MAPE sebesar 9,6%, yang dikategorikan sebagai prediksi yang sangat baik. Sistem ini diimplementasikan pada platform web dengan fitur login, manajemen data, dan prediksi real-time otomatis. Hasil penelitian ini menunjukkan bahwa menggunakan metode KNN untuk memprediksi panen udang vaname mampu membantu petambak membuat keputusan budidaya yang lebih terencana dan berbasis data. Oleh karena itu, sistem tersebut diharapkan dapat meningkatkan efisiensi, produktivitas, dan keberhasilan panen di masa depan.

Abstract

The rapid development of digital technology has encouraged the emergence of new forms of economic transactions, including the purchase of in-game currency through game top-up services. Third-party service providers such as ArgamingShop facilitate players in obtaining in-game currency; however, the transaction mechanism requires examination from the perspective of Islamic sale contract principles. This study aims to analyze the transaction mechanism of in-game currency in ArgamingShop's game top-up service and to examine its conformity with the principles of Islamic sale contracts. This research employed a qualitative field research approach using a case study method. Data were collected through observation, interviews, and documentation, and analyzed using data reduction, data display, and conclusion drawing, with source triangulation employed to ensure data validity. The findings reveal that the transaction mechanism consists of product selection, game account identification, payment, payment verification, and delivery of in-game currency. From the perspective of fiqh muamalah, the transaction fulfills the essential elements of a valid sale contract, including competent contracting parties, a lawful object, a clearly determined price (thaman), and mutual consent (ijab and qabul). Furthermore, the transaction satisfies the legal requirements of Islamic contracts, namely legal capacity, mutual willingness, certainty of the object and price, lawful contractual purpose, and the absence of prohibited elements such as riba, gharar, and maisir. Therefore, the transaction mechanism of in-game currency at ArgamingShop is consistent with the principles of Islamic sale contracts.

Abstract

Abstract This study aims to analyze the development strategies of the Muhammadiyah Layer Chicken Farm in Pucakwangi Village and the implementation of Islamic business ethics principles in promoting business sustainability. The study employed a qualitative approach using a case study design. Data were collected through in-depth interviews with Ali Rofiq, the farm manager, and supported by documentation related to business management. The data were analyzed thematically by identifying business development strategies and examining their relevance to Islamic business ethics principles. The findings indicate that the development of the farm is implemented through five main strategies: community economic empowerment, strengthening marketing networks, production efficiency and innovation, strengthening management and human resources, and capital development through the syirkah system. Business sustainability is further supported by risk management through reserve funds, synergy among Muhammadiyah’s charitable enterprises, and the capacity to adapt to crises, including the COVID-19 pandemic. From the perspective of Islamic business ethics, these practices reflect the principles of amanah (trustworthiness), ‘adl (justice), tabligh (transparency), ihsan (benevolence), and maslahah (public benefit), manifested through transparent management, profit-sharing mechanisms, social responsibility, and a commitment to collective benefit. This study demonstrates that Islamic business ethics function not merely as moral guidelines but also as a foundation for governance, resilience, and sustainability in community-based enterprises. These findings may serve as a reference for developing business units within religious organizations that integrate economic and social interests.
