Abstract

Indonesia terletak di pusat keanekaragaman terumbu karang dunia. Keanekaragaman hayati ini menekankan pentingnya Indonesia dalam upaya global untuk melestarikan sumber daya laut. Penelitian ini akan mengkaji struktur komunitas karang dan kompoisis ikan terumbu yang terdapat pada dua lokasi yang berbeda di dua titik di perairan Sabang, meliputi Pulau Rubiah dan Iboih sebagai perwakilan dari perairan Sabang bagian Selatan. Penelitian ini dilaksanakan pada bulan Agustus 2019. Metode LIT digunakan dalam penelitian ini (Line Intercept Transect) dengan panjang transek 100m. Analisis data karang meliputi persen penutupan karangdan kelimpahan ikan karang dan indeks  Keanekaragamannya. Hasil penelitian menunjukkan persentase tutupan karang di lokasi Pulau Rubiah dan perairan Iboih sebesar 27,76±5,30% dan 26,12±5,85% yang termasuk kedalam kondisi sedang. Dilokasi pertama karang didominasi oleh genus Acropora (16,74%) sedangkan pada lokasi kedua Heliopora (18,45). Komposisi ikan pada lokasi pertama dan kedua didominasi oleh Acanthuridae danPomacentridae dengan persentase yang berbeda pada setiap lokasi. Indeks keanekaragaman pada dua lokasi berada pada kriteria sedang yaitu 2,862 (Pulau Rubiah) dan 2,816 (Iboih).

Abstract

The role of coastal communities in the preservation of coral reefs is an important thing to supporting the sustainable management of coastal areas. This article is objected to determine the coastal communities’ role in the management of coral reefs in water conservation areas and the level of knowledge of the coastal communities about the importance of protecting coastal ecosystems. Data were collected by distributing questionnaires, direct interviews and Focus Group Discussions (FGD) and the results were elaborated based on descriptive analysis. The results showed that the community had begun to realize how important it is to protect coral reefs for the sustainability of fisheries and other benefits of coral reefs. Healthy reefs provide many benefits to people including improving the economy of the community and increasing tourists. Community awareness is shown by their participation in activities that lead to the conservation and management of coral reefs such as transplantation of coral reefs, beach cleaning, banner making, tree planting and provision of trash bins along the coast. Those who knew the benefits and functions of coral reefs both for increasing fish populations, increasing tourists and improving the economy of the community, as well as other benefits of coral reefs for the coastal areas, was 74.5%. The role of community in the aspects of coastal and marine ecosystems management was high, as many as 72% of the community participate in every coastal and marine ecosystem management activity carried out by the government and local NGOs.

Abstract

This study aimed to evaluate of patin seed (Pangasius hypothalamus) that is given Tubifex sp. as additional feed. The experiment design was used  completely randomized design with four treatments and four replications. The treatments studied were 100 % pellet without the addition of Tubifex sp. (A), 95 % pellet with the addition of  Tubifex sp. 5 % (B), 90 % pellet with the addition of  Tubifex sp. 10 % (C) and 85 % pellet with the addition of  Tubifex sp. 15 % (D). Patin seed stocking density was 1 individu/l with the length of  3-4 cm and weight of  0,15-0,28 g. The culture period for one cycle of fish farming was 40 days. The ANOVA test showed commercial feeding with the addition of Tubifex sp. as additional feed gave the significant effect on the specific of growth rate, length and feed conversion ratio, but did not give the significant effect on survival rate of patin seed. The best dose to increase the growth of catfish seeds is 85% commercial feeding with the addition of Tubifex sp. 15%.
