Abstract

The potential of Selar Fish (Selaroides spp.) caught by fishermen in the waters of Donggala Regency requires in-depth study to support sustainable management and ensure its sustainability in the future. This research aims to analyze catch per unit effort (CPUE) as well as the maximum sustainable potential of trevally (Selaroides spp.) in the region. The research location covers three administrative areas, namely Labean Village (Balaesang District), Ogoamas Village (North Sojol District), and Labuan Bajo Village (Banawa District). The research results show that the average trevally production during the 2017-2023 period reached 5,019.06 tons per year, with an average fishing effort of 2,479.66 trips per year. The average catch per attempt (CPUE) was recorded at 2,394.92 tons/trip. Based on analysis using the Schaefer model, the maximum sustainable potential (hMSY) is obtained with a maximum biological production of 6,238 tons per year. Maximum economic profit is achieved at a hMEY production level of 6,152 tons per year, while the equilibrium condition for fisheries in open access (hOAY) occurs at a production level of 2,579 tons per year. In terms of fishing effort, the biologically optimum number of efforts (EMSY) is 3,175 trips per year, economically (EMEY) it is 2,803 trips per year, while in open access conditions (EOAY) it reaches 5,606 trips per year. This data indicates that MEY-based management is more advisable to maximize economic benefits while maintaining the sustainability of trevally resources. These findings can be a basis for policy makers in establishing sustainable fisheries management strategies in the waters of Donggala Regency

Abstract

Seagrass beds are macro and micro habitats for marine aquatic biota. The habitat characteristics formed by seagrass beds are closely related to the species and morphometrics of the species. Enhalus acoroides is a seagrass species that has larger root, rhizome, and leaf morphometrics compared to other seagrass species. This study aims to determine the morphometric characteristics of E. acoroides in the seagrass beds of Malahing Village, Bontang City, East Kalimantan Province. This study was conducted from October 2024 to February 2025. Data collection of E. acoroides, water samples and bottom substrates used a purposive sampling approach divided into 4 stations with 3 replications. Sampling of E. acoroides density used a 50x50cm square frame. Each sample of E. acoroides stands was subjected to morphometric measurements. The density of E. acoroides in the seagrass beds of Malahing Village in the density criteria, the morphometric characteristics of leaves, rhizomes and roots were relatively smaller and associated with the sand bottom substrate.

Abstract

Dalam dinamika bisnis global yang terus berubah, isu Lingkungan, Sosial, dan Tata Kelola (Environmental, Social, and Governance/ESG) telah mengalami pergeseran signifikan dari sekadar kewajiban normatif menjadi elemen strategis yang krusial. Secara historis, praktik akuntansi ESG kerap diposisikan sebagai alat pemenuhan regulasi pelaporan non-keuangan semata. Namun, pendekatan ini dinilai tidak lagi memadai dalam menghadapi kompleksitas tantangan dan ekspektasi pemangku kepentingan masa kini. Studi ini menyoroti pentingnya integrasi akuntansi ESG secara mendalam ke dalam kerangka strategi bisnis dan proses pengambilan keputusan organisasi. Ditemukan bahwa akuntansi ESG yang bersifat strategis slot zeus berpotensi menjadi motor penggerak inovasi, serta sarana untuk membangun keunggulan kompetitif yang berkelanjutan. Tidak hanya berperan dalam mitigasi risiko lingkungan dan sosial, akuntansi ESG juga mampu menciptakan nilai tambah jangka panjang melalui peningkatan efisiensi operasional, reputasi perusahaan, serta kepercayaan investor. Dengan demikian, ESG tidak lagi dipandang sebagai biaya kepatuhan, melainkan sebagai investasi strategis yang berdampak langsung pada kinerja dan keberlanjutan perusahaan. Temuan ini menggarisbawahi perlunya pergeseran paradigma dalam memandang akuntansi ESG: dari pendekatan reaktif menuju pendekatan proaktif yang menyatu dengan visi dan tujuan jangka panjang perusahaan

Abstract

The fishing industry is more popular among the community, and one of the reasons for this is the high demand for fishery products, especially shrimp. The Tanjung Harapan sub-district in Paser Regency has considerable potential for pond-based aquaculture, particularly for tiger shrimp (Penaeus monodon). The favorable geographical conditions and promising business opportunities have made this business a source of livelihood for the surrounding community. However, shrimp pond farming is vulnerable to production fluctuations due to climatic factors, pest and disease attacks, and suboptimal management. The purpose of this study is to assess the financial feasibility of pond farming in Tanjung Harapan Subdistrict, Paser Regency. This study uses analysis methods such as Net Present Value (NPV), Net Benefit Cost Ratio (B/C), Internal Rate of Return (IRR), and Payback Period (PP). The results of the study show that the Net Present Value (NPV) for the next five years for the shrimp farming business is IDR 546,335,336, the Net BCR is 8.35 with an IRR of 166%, and the payback period is 7.18 months.
