Abstract

The coastal waters of Semarang Bay have been polluted by heavy metal lead (Pb). The research was conducted from September 2015 to March 2016 with 3 stations at the Tambaklorok green mussel cultivation location. Analysis of the concentration of heavy metal Pb using the AAS (Atomic Absorption Spectrophotometer) method. Data processing using SPSS and Excel. The results showed that the average concentration of heavy metal Pb in the air ranged from 0.51 to 0.76 mg/L. The average concentration of heavy metal Pb in three observations obtained an average concentration of Pb between 4.975-20.43 mg/kg. Green mussels taken in the waters were sorted and separated according to the length of the shell and weighed 1 kg each according to the length of the shell. Small (2-3 cm), medium (3-4 cm) and large shells with long shells (5-6 cm). The results of the measurement of the concentration of heavy metal Pb in P. viridis showed that the average green mussel shell size 4-5 cm at the location of station III had the lowest concentration of heavy metal Pb at 0.24 mg/kg. Meanwhile, the highest average concentration of Pb in P. viridis was found at station I at 0.89 mg/kg with a shell length of 2-3 cm. The correlation equation between shell length and Pb concentration is Y= - 0.131 + 1.13 X. Standard error of the Estimate (SEE) is 0.19. While the standard deviation of 0.20 means that the predictor variable (water) to predict the dependent variable (shellfish) is feasible because SEE is greater than the standard deviation. The average value of the Bioconcentration Factor (BCF) of green mussels is smaller than that of medium-sized green mussels and large green mussels. Green mussels can be consumed by someone if the body weight is 60 kg, then as much as 5.8 kg in a week because it contains Pb.

Abstract

The Banggai cardinalfish (Pterapogon kauderni Koumans, 1933) is an endemic species that inhabits a limited habitat in shallow waters. This species is a widely traded marine ornamental fish. However, since late 2007, the International Union for Conservation of Nature (IUCN) has classified P. kauderni as an endangered species. Changes in P. kauderni habitat in Palu Bay have been reported, particularly in the waters of Mamboro Village Beach. According to local community information, this species has been introduced to Kayumalue Pajeko Village Beach, also within the Palu Bay area. Daily human activities and environmental changes caused by natural disasters and post-tsunami recovery necessitate annual updates on population development data and habitat conditions. This study aimed to reassess the habitat conditions of P. kauderni in the waters of Kayumalue Village, Palu Bay. Observation results showed that P. kauderni was only found in the macrohabitat of sea urchins. Meanwhile, along the observed transect, no recruit-sized P. kauderni were found. This is suspected to be due to the limited availability of macro habitat types such as anemones or other soft corals.

Abstract

Pantai Tanjung Karang dikenal memiliki potensi yang tinggi untuk dikembangkan sebagai destinasi wisata bahari unggulan di Kabupaten Donggala. Penelitian ini bertujuan untuk mengkaji kesesuaian lahan dan daya dukung lingkungan kawasan tersebut dalam mendukung kegiatan wisata pesisir. Penelitian dilaksanakan pada bulan Agustus sampai dengan September 2024 dengan menggunakan metode survei yang dipadukan dengan pengamatan langsung di lapangan pada tiga stasiun pengamatan yang telah ditentukan. Pengumpulan data dilakukan berdasarkan parameter biofisik yang dianggap penting bagi keinginan dan kelayakan kegiatan wisata bahari. Hasil penelitian menunjukkan bahwa garis pantai yang sesuai untuk pemanfaatan wisata bahari luasnya kurang lebih ±1.002 meter, sedangkan luas perairan yang sesuai untuk berenang sekitar ±5.334 m². Indeks Kesesuaian Wisata (IKW) tercatat sebesar 2,190 pada Stasiun 1 dan 2,130 pada Stasiun 2, keduanya berkategori “sesuai”, sedangkan Stasiun 3 memperoleh nilai sebesar 2,250, berkategori “sangat sesuai”. Berdasarkan analisis daya dukung, Pantai Tanjung Karang diperkirakan dapat menampung hingga 80 pengunjung per hari untuk rekreasi pantai dan 427 pengunjung per hari untuk berenang, sehingga total daya tampung harian maksimum adalah 507 pengunjung. Temuan ini memberikan dasar ilmiah untuk merumuskan strategi pengelolaan dan pengembangan berkelanjutan untuk kawasan wisata pesisir Tanjung Karang.

Abstract

Segmen pendederan udang vannamei dapat dipengaruhi oleh warna tangki hal ini dapat memberikan preferensi yang baik dalam proses awal budidaya udang vanamei. Warna tangki menjadi faktor visual feeding larva udang mengkonsumsi pakan dapat maksimal. Tujuan penelitian ini untuk mengkaji performa Calsium (Ca), mengetahui komposisi tubuh atas hasil respon aktivitas Superoxide dismutase (SOD) pasca pendederan udang vannamei. Hasil penelitian menunjukan bahwa warna tangki mempengaruhi preferensi udang vannamei yaitu aktivitas SOD yang berfariasi pada masing-masing perlakuan. Komposisi udang pasca pendederan cendrung sama yaitu memiliki kadar air yang cukup tinggi, serta kandungan lainnya memiliki nilai yang relatif sama. Namun kandungan Ca pada tubuh udang memiliki nialai yang berbeda. Pada perlakuan D kandungan Ca lebih tinggi di bandingkan dengan perlakuan C,B dan A. SOD tangki berwarna hijau cendrung lebih rendah dari pada warna tangki lainnya. Rendahnya aktivitas SOD tersebut diduga dapat menjadi indikasi preverensi yang baik untuk pendederan udang vannamei.
