Abstract

Kelabau (Osteochilus melanopleurus) is one of the local fish found in Borneo. Economically, kelabau fish has a reason to be cultivated because it has a fairly high price. One of the aspects that needs to be considered is the availability of raw materials. This study aimed to evaluate the use of fermented palm kernel meal in feed on feed conversion, growth, and survival of kelabau. The experimental design applied was a Completely randomized design (CRD) with 4 treatments and 3 replicates, namely (P0) no palm kernel meal added; (P2) palm kernel meal fermented for 0 hours, (P3) palm kernel meal fermentaded for 24 hours, and (P4) palm kernel meal fermented for 48 hours. Fish rearing was carried out for 40 days with feeding experimental frequency three times a day with at satiation. The  fish  was  kelabau  seeds measuring 4-5 cm and weighing 1-2 g. Ovserved variades tested in this study included feed conversion rasio , growth, and survival rate. The highest growth was resulted by  palm kernel meal fermented for 48 hours, the lowest feed conversion ratio (FCR) was resulted by falm kernel meal fermented 24 hours, and the survival of all treatment during this rearing werw 100%. However statisticaly no significant differences were observed in either/ grow or feed conversion ratio.  Kata kunci: Kelabau; EM4;  fermentasi; bungkil inti sawit

Abstract

The abandoned land of coal mining activity in a form of pond was used for fish culture by the people of Kutai Kartanegara Regency of East Kalimantan Province. However, the problem occurs firstly when the land opened for the open pit system that should make the change of water quality of physic, chemistry, and biology of pond after mining activity. This research was done to know the existing condition of former coal mining land, and to analyze the sustainability of aquaculture in this area. Aquaculture sustainability in former coal mining ponds were analyzing with multi dimensional scaling which is a developmental method of Rap-fish (rapid appraisal analysis). The results of the analyzing for every dimension showed that ecological, economical, and sociality has approved index, which mean that balanced were occurred in these dimension for sustainability of the aquaculture activity. The ecological dimension, economy, and social in the developing activity must be in balanced without domination to achieve for sustainability.

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

Sungai Sangatta merupakan sumber daya air strategis di Kabupaten Kutai Timur, Kalimantan Timur, yang menopang kebutuhan domestik, pertanian, perikanan, dan ekosistem akuatik, namun saat ini tekanan pencemaran yang semakin meningkat akibat aktivitas pertambangan, pertanian, industri kecil, dan pemukiman di sepanjang daerah aliran sungai. Penelitian ini bertujuan untuk menganalisis karakteristik kualitas air Sungai Sangatta berdasarkan parameter fisika, kimia, dan biologi, dengan menilai dan membandingkan status mutu airnya menggunakan metode Indeks Pencemaran (IP) dan metode STORET guna mendukung pengambilan kebijakan pengelolaan lingkungan perairan secara berkelanjutan. Pengambilan sampel air dilakukan pada tiga stasiun yang mewakili segmen hulu, tengah, dan hilir sungai menggunakan metode grab sampling sesuai Standar Nasional Indonesia 8995:2021, dengan tiga periode pengamatan antara Februari hingga Maret 2026. Parameter yang dianalisis meliputi suhu, Total Suspended Solid (TSS), pH, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), fosfat, nitrat, dan total coliform, yang seluruhnya dibandingkan terhadap baku mutu air kelas II berdasarkan Peraturan Pemerintah Nomor 22 Tahun 2021. Hasil analisis Indeks Kualitas Air (IKA) menunjukkan ketiga segmen termasuk kategori Baik dengan skor hulu 85,09; tengah 82,76; dan hilir 83,19. Namun, penilaian metode IP mengklasifikasikan bagian hulu sebagai tercemar sedang (IP = 6,36), sementara bagian tengah (IP = 4,40) dan hilir (IP = 3,07) sebagai tercemar ringan, dengan TSS dan COD sebagai parameter pencemar dominan yang melampaui baku mutu secara signifikan pada periode 3 Maret 2026. Metode STORET mengklasifikasikan seluruh segmen sebagai tercemar sedang (Kelas C) dengan skor −12 di hulu, −17 di tengah, dan −18 di hilir. Perbedaan hasil kedua metode menunjukkan bahwa metode STORET lebih sensitif dalam mendeteksi akumulasi pencemaran lintas parameter dibandingkan metode IP yang lebih mencerminkan tingkat pencemaran dominan aktual. Kombinasi penggunaan kedua metode direkomendasikan sebagai pendekatan terpadu dalam pemantauan dan pengendalian kualitas air Sungai Sangatta secara berkelanjutan
