Abstract

Penelitian ini dilakukan untuk menganalisis kontribusi rehabilitasi mangrove terhadap peningkatan stok karbon di Kawasan Ekowisata Mangrove Karangsong, Kabupaten Indramayu. Rehabilitasi mangrove dianggap penting dalam usaha mitigasi perubahan iklim karena kemampuannya dalam menyerap karbon dioksida dari atmosfer. Tujuan penelitian ini mengetahui potensi stok karbon yang dihasilkan dari proses rehabilitasi mangrove dikawasan ini. Penelitian menggunakan metode survey dengan plot penelitian berukuran 10x10 m secara stratified random sampling. Hasil penelitian menunjukkan bahwa rehabilitasi mangrove secara signifikan meningkatkan stok karbon di area tersebut. Stasiun 1 mencatat stok karbon tertinggi dengan total 303,53 ton/ha, sementara Stasiun 3 memiliki stok karbon terendah dengan 138,96 ton/ha. Hasil ini menegaskan bahwa rehabilitasi mangrove tidak hanya berperan dalam konservasi ekosistem, tetapi juga sebagai strategi mitigasi perubahan iklim yang efektif melalui peningkatan penyerapan karbon.

Fakultas Ekonomi dan Bisnis, Universitas Mulawarman, dibawah bimbingan Iskandar, SE., M.Si., AK., CA dan Muhammad Abadan Syakura, SE., MSA., Ak. Penelitian ini bertujuan untuk mengetahui kinerja pengelolaan Pendapatan dan Belanja Daerah Kabupapaten Penajam Paser Utara (PPU) periode 2013-2017. Metode penulisan yang digunakan untuk menganalisis penelitian ini adalah deskriptif kuantitatif. Penelitian ini menggunakan data primer dan sekunder. Teknik yang dikunakan dalam penelitian ini  menggunakan teknik kepustakaan,dokumentasi dan wawancara. Sedangkan alat analisis yang digunakan berupa  Hasil penelitian pada APBD Kabupaten PPU menunjukkan bahwa dalam lima tahun penelitian belum terlalu baik dalam merealisasikan pendapatan daerahnya. Berbeda dengan belanja daerah, dalam lima tahun penelitian sudah baik dalam merealisasikan belanjanya dengan tidak melebihi jumlah yang dianggarkan.

Abstract

Feed availability is a crucial factor in aquaculture, accounting for approximately 6070% of total production costs. High-quality feed is often expensive due to reliance on imported ingredients. To address this issue, animal-based organic waste presents a promising alternative, given its abundance, underutilization, and high nutritional value when properly processed. This review was conducted from November 2024 to January 2025 using a narrative literature review approach, synthesizing previous publications to identify research gaps and development opportunities. Literature was sourced from national and international scientific databases, including Scopus, ScienceDirect, SpringerLink, and ResearchGate. The study aimed to explore the production of fermented animal by-product meal and its application in aquafeed to enhance fish growth performance. Findings indicate that fermentation significantly improves the nutritional quality of animal waste. Several reviewed studies reported that incorporating fermented by-products such as fish offal, poultry feathers, and blood at inclusion levels of 2025% can improve the growth and survival rates of juvenile fish. Therefore, the optimal use of such ingredients is recommended to reduce feed costs and support the sustainability of aquaculture systems.Keywords:Alternative ingredientsFish wasteChicken Feather WasteBlood WasteFermentationFish feed

Abstract

The male broodstock of Transgenic Mutiara catfish (P) (containing Clarias gariepinus Growth Hormone, CgGH) is a fish who show fast growth. Propagation of the Transgenic Mutiara catfish F1 and F2 progeny involves the crossing of broodstock P with Non Transgenic Mutiara catfish. New genetic variations (polymorphisms) can be generated from crosses broodstock P and F1 which lead to the fast growth inheritance of transgenic fish. Phylogenetic relationship analysis showed distance and genetic variation in broodstock P, F1, F2 and Sangkuriang catfish (as controls) using the RAPD-PCR method (Random Amplified Polymorphic DNA-Polymerase Chain Reaction) as the research purposes. The results showed that OPA-03 (5'-AGTCAGCCAC-3 ') primer was selective for determining phylogenetic among catfish samples. The closest genetic similarity index originates from the female broodstock of Non Transgenic Mutiara catfish (P) (93%), while the farthest originates from the male broodstock of Mutiara Transgenic catfish (P) (51%) with F1 dan F2. Closely related broodstock catfish is not recommended to be crossed.

Abstract

Food and feeding habits are important things in bioecological of fish. This study provides an understanding of the feeding habits and intensity of the M. gulio, by analyzing its food composition, relative gut length (RGL) and gastro-somatic index (GaSI). Fish specimens were caught with a gill net and fishing rod in an area of Cianjur estuaries during a period of one year from October 2021 to September 2022. The analysis of 452 fish samples shows that the relative gut length (RGL) values revealed the feeding habit of M. gulio as carni-omnivorous. The GaSI value was used to determine feeding intensity and was found to be highest in November, at Cidamar estuary, and in the second size group (7.1-10 cm). These results provide new knowledge on this fish species’ feeding habit and intensity, which also helps understand the fish adaptation and conservation in the study area.
