Abstract

Seagrass as a flowering plant (Angiosperms) that can live in the marine environment well. One type of seagrass whose presence is dominant in Indonesian waters is the species Thalassia hemprichii and Cymodocea rotundata. Periphyton is an organism that has a close relationship with seagrass and has a role in seagrass as an increase in primary productivity. The purpose of this study was to determine the genus composition and density of periphyton on seagrass leaves Thalassia hemprichii and Cymodocea rotundata on Panjang Island, Jepara. The method carried out is seagrass leaf field data collection using the purposive sampling method with squared line transects. Seagrass leaf samples were taken and periphyton identification observations were made in the laboratory and then data processing analysis. Periphyton results were obtained from 10 classes, 39 genera and 1 type of zooplankton. Seagrass leaf periphyton density in both species is highest in old leaves and lowest in medium seagrass leaves. The periphyton diversity index of two seagrass species belongs to the medium category, the uniformity index belongs to the high category, and the dominance index shows that no genus dominates. The index value can indicate that the waters in the environment are still in stable condition.

Abstract

Jumlah sapi perah di Kabupaten Tasikmalaya masih sedikit jika dibandingkan daerah lain yang sudah menjadi sentra pengembangan sapi perah. Prospek pengembangan ternak sapi perah memerlukan kesiapan penyediaan pakan yang memadai untuk mendukung penambahan populasi ternak sapi perah. Tujuan penelitian: 1) Menganalisis tipologi peternakan dan logistik pakan; 2) Menganalisis prospek pengembangan pada peternakan sapi perah. Penelitian dimulai dari bulan Juni – Juli 2023 melalui metode survei menggunakan analisis deskriptif pada tipologi peternakan dan logistik pakan, serta strategi pengembangan (analisis SWOT). Kabupaten Tasikmalaya prospektif untuk pengembangan sapi perah menurut hasil penelitian dengan mempertimbangkan terlebih dahulu aspek logistik pakannya untuk dapat mendukung upaya peningkatan populasi ternak sapi perah. Hasil analisis prospek pengembangan sapi perah, Kabupaten Tasikmalaya berada pada Kuadran I. Strategi pengembangan sapi perah yang paling sesuai yaitu strategi agresif (growth oriented strategy) dengan prospek utama pada kemajuan usaha melalui kekuatan dan peluang yang dimiliki. Strategi yang disarankan yaitu: 1) Peningkatan pada sarana untuk logistik pakan, 2) Integrasi sapi perah dengan pertanian (padi, jagung), 3) Introduksi teknologi pengolahan pakan, 4) Memaksimalkan penggunaan lahan untuk penanaman hijauan berkualitas, dan 5) Mengoptimalkan peran koperasi dalam menyediakan pakan yang dibutuhkan. Saran penelitian yaitu pertimbangan kajian logistik pakan dan hasil analisis prospek pengembangan ternak untuk pengembangan sapi perah.

Abstract

The decline in fish stocks, resulting from habitat degradation and overfishing, has become a significant threat to the sustainability of fisheries in Indonesia. One of the efforts to support ecosystem recovery and improve fishermen’s catches is the application of artificial fish apartments. This study aims to analyse the implementation process and effectiveness of artificial fish apartments in the waters around the Tanjung Jati B Power Plant in Jepara. The programs were carried out through a participatory approach with local fishing communities, including socialization, scuba diving training, concrete module construction, installation, and evaluation. A total of five artificial fish apartment units were installed at two sites, namely Karang Pringitan (3 units) and Karang Ketapang (2 units). Evaluation three months after installation showed an increase in fish communities, with 16 species recorded at Karang Pringitan and 9 species at Karang Ketapang. These results confirm that artificial fish apartments can serve as new habitats for pelagic and target fish species and have the potential to support the sustainability of local fisheries.
