Abstract

The presence and establishment of invasive alien fish species is one of the biggest threats to aquatic biodiversity. The red devil, Amphilopus citrinellus, is one of the emerging invasive species and its occurrence is massively detected in common water bodies in tropical areas such as Indonesia. However, the topic remains under-reported from the small urban lakes. This study aims to present the reproductive characteristics of the fish in Situ Cilodong, a small urban lake in the country, that can be used as a principal reference for population control. The sampling was conducted in June 2021 and May 2022 using a mix of seven mesh-sized gillnets. The results of the length-weight relationship reveal that both the female and male fish perform isometric growth type. The calculated Gonad Somatic Index (GSI) and the histological analysis confirmed that the fish is a multi-spawner species. The results imply that sustainable population control efforts must include intensive catch and engage a participatory approach between the legal authority and the local fishers.

Abstract

This study aims to analyze the epistemological framework of Islamic economics based on the thoughts of Masudul Alam Choudhury. Islamic economics is not merely a system of financial instruments but a comprehensive framework grounded in moral, ethical, and spiritual values derived from Islamic teachings. This research employs a qualitative approach using library research methods by examining various academic sources such as books and scientific journals. The findings indicate that Choudhury’s concept of tawhidi epistemology emphasizes the integration of knowledge, religion, and socio-economic systems into a unified and dynamic framework. The principles of Islamic economics, including unity (tauhid), justice, productivity, and wealth distribution, offer a holistic solution to the limitations of conventional economic systems. Furthermore, Islamic political economy, as proposed by Choudhury, integrates economic, social, and political dimensions through participatory and ethical mechanisms. Therefore, his framework contributes significantly to the development of a more just, sustainable, and value-based economic system

Abstract

Keterbatasan lahan budidaya air tawar (freshwater pond) merupakan salah satu kendala pembesaran udang galah yang selama ini menjadi penyebab sedikitnya produksi udang galah di Indonesia. Penelitian ini bertujuan untuk mengetahui pengaruh media bersalinitas terhadap kelangsungan hidup dan pertumbuhan udang galah, dengan memanfaatkan sifat euryhaline yang dimiliki oleh udang galah.Hasilnya diharapkan bermanfaat bagi upaya pemeliharaan udang di tambak (brackishwater pond) sebagai salah satu lahan yang bisa dimanfaatkan dalam budidaya udang galah. Media yang digunakan sebagai perlakuan adalah air bersalinitas 3 ppt, 6 ppt, 9 ppt, 12 ppt, 15 ppt, dan air bersalinitas 0 ppt sebagai kontrol. Media ditempatkan pada akuarium berukuran (80x40x40) cm3. Udang uji yang digunakan berumur 2 bulan dengan panjang total dan bobot awal masing-masing4,87±0,448 cm dan 0,68±0,193 gr. Pada setiap akuarium diisi dengan 15 ekor udang uji. Parameter utama yang diamati adalah tingkat kelangsungan hidup, pertumbuhan bobot dan panjang, serta laju pertumbuhan hariannya. Dengan menggunakan Rancangan Acak Lengkap (RAL). Kelangsungan hidup tertinggi (P<0,05) diperolehdari perlakuan media bersalinitas 3 ppt, 6 ppt, 9 ppt dan 12 ppt. Sedangkan pertumbuhan bobot tertinggi (P<0,05) diperoleh pada salinitas 0 ppt, 3 ppt, 6 ppt dan 9 ppt, sementara pada pertumbuhan panjang, laju pertumbuhan harian bobot serta laju pertumbuhan harian panjang tidak menunjukkan perbedaan yang nyata (P>0,05).
