Abstract

Coral reefs are one of the most productive and diverse ecosystems on earth and provide ecosystem services. One of the islands of the Seribu Islands that has a coral reef ecosystem is Tidung Island. It is strategic and developing location makes this island used as a residential area, conservation area, and tourist destination. But the utilization has an impact on the damage of coral reefs through environmental and anthropogenic pressures. This study aims to determine coral diversity by identifying the coral genus Scleractinia and the factors that affect coral diversity. Observations were done on three different stations include 2 snorkeling areas and 1 natural area. The method used is LIT (Line Intercept Transect) and coral genus identification with Coral Finder Toolkit Indo Pacific 3.0. The results of identification obtained 16 coral genera namely genus Acropora, Montipora, Isopora, Favites, Leptastrea, Favia, Goniastrea, Montastrea, Platygyra, Echinopora, Porites, Pocillopora, Stylophora, Ctenactis, Pavona, dan Symphyllia, with the value of Diversity Index (H') in the waters of Tidung Island ranges from 0.94 – 2.34  in the category of low to moderate diversity. The parameters of water quality in Tidung Island, temperature, salinity, and acidity (pH) are relatively good for coral growth, but brightness is still relatively poor for coral growth. The impact of human activities such as snorkeling, ship anchors, fishing with destroyers, oil and waste pollution, and rock mining are factors that affect coral growth and diversity.Keywords: Coral Scleractinia; Limiting Factors; Coral Finder; Tidung IslandAbstrakTerumbu karang adalah salah satu ekosistem yang paling produktif dan beragam di bumi serta menyediakan jasa ekosistem. Salah satu pulau dari gugusan Kepulauan Seribu yang memiliki ekosistem terumbu karang yaitu Pulau Tidung. Letaknya yang strategis dan berkembang menjadikan pulau ini dimanfaatkan sebagai kawasan permukiman, daerah konservasi, dan kawasan tujuan wisata. Namun dari pemanfaatan tersebut memberikan dampak terhadap kerusakan pada terumbu karang melalui tekanan-tekanan lingkungan maupun antropogenik. Penelitian ini bertujuan untuk mengetahui keanekaragaman karang dengan mengidentifikasi genus karang Scleractinia dan faktor yang mempengaruhi keanekaragaman karang. Pengamatan di tiga stasiun berbeda yaitu di antaranya 2 kawasan wisata snorkeling, dan 1 kawasan yang masih alami. Metode yang digunakan yaitu LIT (Line Intercept Transect) dan identifikasi genus karang dengan Coral Finder Toolkit Indo Pasific 3.0. Hasil identifikasi didapatkan 16 genus karang yaitu genus Acropora, Montipora, Isopora, Favites, Leptastrea, Favia, Goniastrea, Montastrea, Platygyra, Echinopora, Porites, Pocillopora, Stylophora, Ctenactis, Pavona, dan Symphyllia, dengan nilai Indeks Keanekaragaman (H’) di perairan Pulau Tidung berkisar 0,94 – 2,34 berada pada kategori keanekaragaman rendah hingga sedang. Parameter kualitas perairan di Pulau Tidung, suhu, salinitas, dan derajat keasaman (pH) tergolong baik bagi pertumbuhan karang, namun kecerahan masih tergolong kurang baik bagi pertumbuhan karang. Dampak aktivitas manusia seperti snorkeling, jangkar kapal, penangkapan ikan dengan alat perusak, pencemaran minyak dan sampah, serta penambangan batu karang menjadi faktor yang mempengaruhi pertumbuhan dan keanekaragaman karang.

Abstract

Indonesia is a tropical country with high marine biodiversity, including sea cucumber. The high demand for sea cucumber has led fishermen to catch sea cucumber regardless of the type or size suitable for harvesting. The lack of cultivation and regulations governing the protection of sea cucumbers has caused some species to be endangered. Sea cucumber species with high selling prices are increasingly difficult to find in West Likupang District. This study aims to identify strategies for managing sea cucumber fisheries sustainably and provide policy recommendations for their sustainable management in West Likupang District. This study used a survey method and then analyzed it with a SWOT analysis (strengths, weaknesses, opportunities, threats). The SWOT analysis reveals several strategies for achieving sustainable sea cucumber fisheries: legislation, conservation efforts, aquaculture development, regulated fishing, proper post-harvest handling, and educating fishermen on regulations. Keywords: Management, regulation, conservation, sea cucumber, SWOT Abstrak Indonesia merupakan negara tropis yang mempunyai keanekaragaman hayati laut yang tinggi, salah satunya ialah sumber daya trepang (Holothuridea). Permintaan pasar yang tinggi terhadap trepang, menyebabkan nelayan menangkap trepang tanpa mengindahkan jenis dan ukuran yang layak panen. Belum adanya budi daya dan regulasi yang mengatur perlindungan terhadap trepang menyebabkan beberapa spesies sudah terancam punah. Spesies trepang dengan harga jual yang tinggi makin sulit ditemukan terutama di Kecamatan Likupang Barat. Penelitian ini bertujuan untuk menentukan strategi pengelolaan sumber daya perikanan trepang, untuk mencapai perikanan trepang yang berkelanjutan, dan membuat rujukan atau rekomendasi kebijakan untuk pengelolaan sumber daya perikanan trepang (Holothuroidea) yang berkelanjutan secara umum Di Provinsi Sulawesi Utara, khususnya di Likupang Kabupaten Minahasa Utara. Penelitian ini menggunakan metode survei kemudian dianalisis dengan analisis SWOT (kekuatan, kelemahan, peluang, dan ancaman). Berdasarkan hasil analisis, terdapat beberapa strategi yang dapat dikembangkan untuk mencapai perikanan trepang yang berkelanjutan, yakni: regulasi berupa peraturan perundangan, upaya konservasi, pengembangan usaha budidaya, penangkapan yang terukur, penanganan pasca panen/penangkapan dari alam, dan sosialisasi kepada nelayan terkait peraturan Kata kunci: Pengelolaan, regulasi, konservasi, trepang, SWOT

Abstract

This study aims to (1) evaluate the concentration of detergents in the water of the Dayanan River, (2) analyze the ability of Pistia stratiotes to reduce detergents, and (3) evaluate the effect of phytoremediation media on the physiological response of carp (Cyprinus carpio). The study used a Complete Random Design (RAL) with a plant contact time treatment of 3 and 6 days on two types of media (river water and well water + 10 mg/L detergent), as well as three replicas. Detergent analysis was carried out using the SNI 06-6989.51-2005 spectrophotometry method. The results showed that the highest concentration of detergent in the Dayanan River was found in the middle (0.0497 mg/L). Pistia stratiotes effectively reduced detergent significantly (p = 0.025) with optimal time on the third day. The fish response showed an increase in the frequency of operculum opening on the third day (p = 0.004) and no mortality was found for 48 hours. These results prove that Pistia stratiotes is effectively used as a natural biofilter to reduce the detergent content in waters. Keywords: detergent, Pistia stratiotes, phytoremediation, common carp (Cyprinus carpio), Dayanan River Abstrak Penelitian ini bertujuan untuk (1) mengevaluasi konsentrasi detergen dalam air Sungai Dayanan, (2) menganalisis kemampuan Pistia stratiotes dalam mereduksi detergen, dan (3) mengevaluasi efek media hasil fitoremediasi terhadap respon fisiologis ikan mas (Cyprinus carpio). Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan perlakuan waktu kontak tanaman 3 dan 6 hari pada dua jenis media (air sungai dan air sumur + detergen 10 mg/L), serta tiga ulangan. Analisis detergen dilakukan menggunakan metode spektrofotometri SNI 06-6989.51-2005. Hasil penelitian menunjukkan bahwa konsentrasi detergen tertinggi di Sungai Dayanan terdapat pada bagian tengah (0,0497 mg/L). Pistia stratiotes efektif mereduksi detergen secara signifikan (p = 0,025) dengan waktu optimal pada hari ketiga. Respon ikan menunjukkan peningkatan frekuensi bukaan operkulum pada hari ketiga (p = 0,004) dan tidak ditemukan mortalitas selama 48 jam. Hasil ini membuktikan bahwa Pistia stratiotes efektif digunakan sebagai biofilter alami untuk menurunkan kandungan detergen di perairan. Kata kunci: detergen, Pistia stratiotes, fitoremediasi, ikan mas (Cyprinus carpio), Sungai Dayanan
