Abstract

Penelitian ini bertujuan untuk mengetahui kondisi sosial ekonomi masyarakat pembudidaya rumput laut di kawasan pesisir Kecamatan Arungkeke, Kabupaten Jeneponto, Sulawesi Selatan. Penelitian dilaksanakan pada bulan Juni sampai November 2019. Penelitian ini adalah penelitian diskriptif kuantitatif pada aspek yaitu kondisi sosial masyarakat (kondisi tempat tinggal dan pendidikan), kondisi ekonomi (jenis pekerjaan dan tingkat pendapatan). Pengumpulan data menggunakan angket dan wawancara terstruktur kepada 45 rumah tangga sebagai responden. Hasil penelitian menunjukkan secara umum tingkat pendapatan masyarakat Kecamatan Arungkeke masih sangat rendah. Demikian pula, pendapatan masyarakat pembudidaya rumput laut. Mayoritas masyarakat bekerja sebagai petani, sedangkan masyarakat yang bekerja sebagai pembudidaya rumput laut sebagian besar bekerja sebagai nelayan. Masyarakat Arungkeke sudah memiliki tempat tinggal layak huni sesuai dengan beberapa kriteria serta status kepemilikan bangunan milik sendiri. Berdasarkan tingkat pendidikan secara umum masyarakat berpendidikan rendah dengan tingkat pendidikan terakhir Sekolah Dasar (SD), begitu juga pada rumah tangga sebagai pembudidaya rumput laut secara umum berpendidikan terakhir Sekolah Dasar.

Abstract

In addition to having high economic value, catfish (Clarias sp.) can also be cultivated quickly and they can adapt well. The demand of catfish is in line with the increase in production which is expected to remain efficient and environmentally sound. Biofloc technology has also been implemented in catfish for increasing productivity. Biofloc utilizes the activity of heterotrophic microorganisms and autotrophs for the conversion of organic waste into floc and is used as fish feed. This study aims to examine the effect of the use of molasses with different doses (C/N ratio) on the growth and survival rate of catfish. This study was conducted with as many as 3 treatments with 3 repetitions each except for the control. The treatment with the ratio of molasses in each of them: A: C/N of 10:1; B: C/N of 15:1; C: C/N of 20:1, and D without molasses given as control. The study using 240 catfish measuring 10-12 cm was carried out for 30 days with sampling every 10 days. It aims to determine the average growth, daily growth, and survival rate of test biota during the study. Based on the results of this study, it can be concluded that the use of different doses of molasses in catfish farming, and biofloc technology will affect the growth and survival rate of farmed catfish. Catfish farmed with biofloc technology at a C/N ratio of 15:1 show the best results on their growth and survival rate. In addition, catfish farming with a biofloc C/N ratio of 15:1 has a better economic analysis when compared to conventional catfish farming. In summary, the use of biofloc based on research results can be a recommendation to be applied in the community, especially among catfish farmers.

Abstract

Eksplorasi mineral logam tertentu dikhawatirkan dapat menyebabkan adanya limbah tambang berupa logam berat yang mencemari air dan sedimen di kawasan pesisir Kabupaten Kepulauan Sangihe, Provinsi Sulawesi Utara. Penelitian ini bertujuan untuk mengetahui konsentrasi dan status mutu logam berat dalam air dan sedimen sehubungan dengan potensi pencemaran yang mungkin terjadi dalam hubungannya dengan pengembangan marikultur. Penelitian dilaksanakan di kawasan pesisir Teluk Talengan, Manalu, dan Dagho dan sekitarnya dengan mengambil sampel air dan sedimen dan selanjutnya dianalisis di laboratorium untuk logam berat Cu, Fe, Hg, Pb, dan Zn. Statistik deskriptif digunakan untuk menganalisis data yang ada dan selanjutnya metode Storet (Storage and Retrieval) digunakan untuk menentukan status mutu air dan sedimen dari logam berat untuk biota laut. Hasil penelitian menunjukkan bahwa dari lima logam berat yang dianalisis dalam air dan sedimen, dijumpai satu di antaranya Hg yang tidak terdeteksi di kawasan pesisir Kabupaten Kepulauan Sangihe. Hasil penentuan status mutu air dan sedimen menunjukkan bahwa air di kawasan pesisir Kabupaten Kepulauan Sangihe tergolong tercemar berat dari logam berat Cu dan Pb untuk biota laut, sedangkan sedimennya tergolong memenuhi baku mutu logam berat untuk biota laut. Konsentrasi logam berat Cu dan Pb dalam air telah melampaui baku mutu logam berat untuk biota laut.
