Abstract

Penyu adalah biota yang termasuk kategori hewan dilindungi, karena memiliki tingkat keterancaman punah yang tinggi dari faktor alami maupun antropogenik. Penyu menghabiskan hidupnya di laut lepas dan pergi ke daratan untuk bertelur pada setiap musimnya. Keberhasilan penetasan telur penyu menjadi hal yang penting sebagai upaya untuk menambah populasinya. Penelitian ini bertujuan untuk menganalisis keberhasilan daya tetas telur penyu hijau (Chelonia mydas) serta penyu sisik (Eretmochelys imbricata) di Pulau Mangkai Kabupaten Kepulauan Anambas. Penelitian dilakukan pada tahun 2022 di bagian utara (Pantai Empung) dan selatan Pulau Mangkai (Pantai Pantai Suit, Pantai Skanji dan Pantai Teluk Kado). Penelitian dilakukan dengan melakukan pengamatan pada kondisi pantai pendaratan, jumlah sarang, jumlah telur, probabilitas dan frekuensi penyu bertelur, persentase telur menetas, hatching success dan persentase tukik hidup dan rilis. Hasil penelitian menunjukkan bahwa terdapat dua jenis penyu yaitu penyu hijau (Chelonia mydas) dan penyu sisik (Eretmochelys imbricata) yang melakukan pendaratan di Pulau Mangkai. Probabilitas penyu bertelur terjadi selama 8 bulan dan probabilitas tertinggi didapat pada bulan Juni (100 %). Terdapat 615 sarang semi alami dan 4 sarang alami, di mana jumlah sarang tertinggi berada pada bulan Juni dengan total 164 sarang dari jenis penyu hijau. Jumlah telur yang ditemukan sebanyak 55.916 butir dan total telur yang menetas sebanyak 48.864 telur penyu. Rata-rata persentase hatching success didapatkan sebesar 86.27%, rata-rata persentase tukik hidup dan rilis sebesar 99.2%. Total tukik hidup dan yang berhasil dirilis di Pulau Mangkai sebanyak 48.276 ekor.  Sea turtles are one of the protected biota species because they have a high level of endangerment from both natural and anthropogenic factors. Turtles spend their lives on the high seas and go ashore to lay their eggs every season. The success of hatching turtle eggs is essential to increase their population. This study analyzes the hatching success rates of green sea turtles (Chelonia mydas) and hawksbill sea turtles (Eretmochelys imbricata) on Mangkai Island, Anambas Islands Regency. The research was conducted in 2022 in the northern (Empung Beach) and southern parts of Mangkai Island (Suit Beach, Skanji Beach, and Teluk Kado Beach). The research was conducted by observing the conditions of the number of nests, the number of eggs, the probability and frequency of turtle laying eggs, the percentage of hatching eggs, hatching success, and the rate of live and released hatchlings. The results showed that two types of turtles, namely the green sea turtle (Chelonia mydas) and the hawksbill sea turtle (Eretmochelys imbricata), landed on Mangkai Island. The probability of laying eggs occurs for eight months, and the highest probability is obtained in June (100%). There were 615 semi-natural nests and 4 natural nests, where the highest number was in June, with a total of 164 nests of green sea turtles. The number of eggs found was 55,916, and 48,864 turtle eggs were hatched. The average percentage of hatching success was 86.27%, and the average percentage of live and released hatchlings was 99.2%. The total number of live and successfully released hatchlings on Mangkai Island was 48,276.

Abstract

The Pieh Island National Marine Protected Area (NMPA) is managed by the LKKPN (National Marine Protected Area Office) Pekanbaru and includes distinct zones: a 197.34-hectare core zone, a 39,681.1-hectare limited utilization zone, and a 41.56-hectare anchoring and habitat rehabilitation zone. The largest, the limited utilization zone, highlights the importance of managing human interactions within the MPA. This research focuses on identifying and exploring strategies to address challenges faced by LKKPN Pekanbaru in managing the Pieh Island NMPA, specifically using the Bando Island area as a case study. Bando Island, a survival tourism destination within the MPA, needs to be more adequately managed. A literature review and data collection through focus group discussions (FGD) were conducted. Issues were explored and validated using the APKL (Aktual, Problematik, Khalayak, Layak) analysis, with priorities determined by the USG (Urgency, Seriousness, Growth) matrix. Fishbone analysis was used to identify root causes of top-priority issues, and alternative strategies were ranked using the McNamara approach. The research identified the lack of stakeholder collaboration as the primary issue, leading to the development of the "KADO SPESIAL" model—focusing on stakeholder involvement in every phase of the management process.

Abstract

The Anambas Islands is one of the regencies in the administrative area of the Riau Islands Province. The sea waters of the Anambas Islands are one of the regions that are strategic in Indonesia because they are located in the South China Sea and bordered by Malaysia, Singapore, Vietnam, and Thailand. Understanding the location of hot spots of fishing activities in this area is very useful for knowing fishing areas as the basis for fisheries management, and potential fish stocks and distributions estimation. This study aims to determine the distribution of fishing vessels in the Anambas Islands, and the distribution of hot spots of fishing vessel locations in the Anambas Islands from 2014 to 2020. The method used is Optimized Hot Spot Analysis which runs the Hot Spot Analysis algorithm by calculating Getis-Ord Gi* statistics on each pixel of the fishing vessels detection image. The study found that the Tokongnanas hot spots cluster was a cluster that consistently appeared from 2014 to 2020. The Mubur, SW Munjan, E Munjan, S Lingai, and Mengkait hot spot clusters were found relatively new. The increase in the number of fishing boats detected in those new hot spot clusters is thought due to the increasing number of squid fishing gear in the area.
