Abstract

Destructive fishing such as using cyanide in capture of ornamental fish has caused damage to the coral reefs, this is suggested the use of clove oil which considered eco-friendly fishing. This study aims to analyze the changes of color, zooxanthellae density and mitotic index of coral Porites lobata after exposure to several concentrations of clove oil. Experimental design was a factorial design, which consists of six concentrations and five time treatments with 3 replication. Coral was placed into the 1.0x0.5x1.0 m aquarium that contains clove oil solution in different concentrations (control, 20, 30, 40, 50, and 60 ppm) for 5 min and then transferred to a tank containing clean seawater for 60 seconds and then removed to tanks for the recovery process. Observation was made everyday for coral color changes in 17 days period and on day 1, 5, 9, 13 and 17 for zooxanthellae density and mitotic index.  The results showed that the were no changes in Porites lobata colors until the 17th day after exposure to 20–60 ppm of clove oil and there was no significant difference in the zooxanthellae density and mitotic index of the Porites lobata on concentration variation, while zooxanthellae densities and mitotic index showed significant difference on time (day) variation. This suggested that exposure to clove oil at  a concentration of 20–60 ppm did not affect the color change, zooxanthellae density and mitotic index of Porites lobata.

Abstract

The increasing demand for live ornamental fish for export needs triggers fishermen to start looking for alternative fishing techniques that are more effective and efficient. The technique commonly used is the anesthetic technique using potassium cyanide. The use of cyanide has been banned by the government because of the many impacts it has caused such as the degradation of coral reef ecosystems, high non-target fish mortality and pollution of coastal areas. Clove oil is an alternative anesthetic which can be utilized with many advantages compared to cyanide. The sampled fish used was sergeant major (Abudefduf vaigiensis) as many as 15 fish with a size of 9-12 cm obtained from fishermen's catch using a scoop. The purpose of this study was to determine the optimal concentration of clove oil as an anesthetic of Sergeant Major Fish (Abudefduf vaigiensis) based on induction time  and recovery time. The experimental design used was a Completely Randomized Design (CRD). Analysis of the data used is One-Way ANOVA parametric analysis and Kruskal Wallis nonparametric analysis. The results obtained are five series of concentrations (20 ppm, 30 ppm, 40 ppm, 50 ppm, 60 ppm) which have a significant effect on induction time (20 ppm and 60 ppm) of sergeant major fish (Abudefduf vaigiensis) (P<0.05) The treatment of five concentration series (20 ppm, 30 ppm, 40 ppm, 50 ppm, 60 ppm) did not have a significant effect on the recovery time of the Sergeant Major Fish (Abudefduf vaigiensis) (P>0.05).

Abstract

Mikroplastik merupakan masalah yang sudah bersifat global dan menjadi ancaman bagi biota di perairan khususnya biota filter feeder seperti kerang hijau (Perna viridis). Penelitian ini telah dilakukan pada bulan Juni sampai Agustus tahun 2019 yang bertujuan untuk mengetahui konsentrasi mikroplastik pada kerang hijau (Perna viridis) yang berasal dari Perairan Mandalle, Kabupaten Pangkajene Kepulauan, Sulawesi Selatan. Sampel kerang yang dikumpulkan sebanyak 99 individu yang dibagi dalam tiga kelompok ukuran panjang cangkang kerang yaitu ukuran 2-3,9 cm, 4-5,9 cm dan 6-7,9 cm. Pengamatan dan penghitungan jumlah mikroplastik dilakukan dengan metode observasi visual menggunakan mikroskop stereo. Hasil penelitian menunjukkan bahwa rata-rata konsentrasi mikroplastik yang didapatkan pada kerang hijau paling tinggi pada ukuran 2-3,9 yaitu 1,87 item/g, kemudian ukuran 4-5,9 cm dengan konsentrasi 0,39 item/g dan konsentrasi terendah pada ukuran 5-6,9 cm yaitu 0,18 item/g. Mikroplastik yang ditemukan hanya satu jenis yaitu fiber yang ukurannya berada pada rentang 0,3-4,4 mm. Warna mikroplastik yang ditemukan terdiri dari empat jenis yaitu biru, merah, hitam, dan bening. Kesimpulannya, kerang hijau yang hidup di Perairan Mandalle telah terkontaminasi oleh mikroplastik baik ukuran kecil maupun ukuran besar meskipun konsentrasinya lebih banyak pada ukuran kecil.

Abstract

Penelitian ini menganalisis kandungan logam berat timbel (Pb) dan kadmium (Cd) pada ikan gabus (Channa striata) dan ikan tawes (Barbonymus gonionotus) dari Danau Tempe, Kabupaten Wajo, Sulawesi Selatan, yang merupakan ikan konsumsi utama masyarakat setempat. Meningkatnya aktivitas manusia di sekitar danau menambah risiko pencemaran logam berat yang berpotensi membahayakan kesehatan. Tujuan penelitian ini adalah untuk menganalisis kandungan logam berat timbel (Pb) dan kadmium (Cd) pada ikan gabus (Channa striata) dan ikan tawes (Barbonymus gonionotus) serta menilai tingkat keamanannya untuk dikonsumsi berdasarkan ambang batas yang ditetapkan oleh Standar Nasional Indonesia (SNI).  Sampel diambil dari nelayan lokal antara Desember 2021 hingga Maret 2022 dan dianalisis dengan metode Atomic Absorption Spectrophotometry (AAS). Hasilnya menunjukkan kandungan timbel (Pb) pada ikan gabus dan tawes masing-masing berkisar antara 2,01–2,70 mg/kg dan 2,35–3,09 mg/kg, melebihi ambang batas SNI sebesar 2,0 mg/kg. Oleh karena itu, ikan ini dinyatakan tidak layak dikonsumsi karena kandungan timbel (Pb) yang tinggi, sementara kandungan kadmium (Cd) pada ikan gabus dan ikan tawes yang terdeteksi hanya sebesar <0.25 yang menandakan dibawah nilai ambang batas dan dianggap aman dan layak konsumsi.

Abstract

Mangrove ecosystems are essential in mitigating climate change through Carbon storage in sediments. This study aims to analyze the bulk density values, carbon concentration, and Carbon storage and absorption in mangrove sediments in Borongkalukua, Maros Regency. Sampling was carried out at five sediment depths (0-10 cm, 10-20 cm, 20-30 cm, 30-40 cm, and 40-50 cm) using the Loss on Ignition (LOI) method and analyzed statistically using one-way and two-way ANOVA. The results showed an average bulk density value of 0.33 g/cm³, with the highest value at a depth of 30-40 cm (0.28 g/cm³). Furthermore, the average Carbon concentration was 11.37%, with the highest value at a depth of 40-50 cm (20.50%) and the lowest at 0-10 cm (1.98%), with no significant differences between depths (p-value > 0.05). Meanwhile, Carbon storage in sediment reached 2,423.77 tons/ha. Total absorption reaching 8,895.23 tons/ha. In conclusion,  sediment depth affects carbon accumulation, with higher carbon content in deeper layers due to the sedimentation process and minimal decomposition. This study emphasizes the importance of mangrove conservation in supporting Carbon storage and climate change mitigation.
