Description 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.
