The condition of coral fish will improve if the health of coral reefs has a direct impact on the abundance of coral fish. The literature review aims to identify coral fish species and the abundance of individual coral fish in Indonesian waters. This study is a literature review containing journal articles from 2010 to 2024 from the Google Scholar database. The results of the study show that the coral fish species found in Indonesian waters include Acanthuridae, Scaridae, Haemulidae, Mullidae, Lutjanidae, Caesionidae, Serranidae, Siganidae, Sphyraenidae, Pomacentridae, Chaetodontidae, Mullidae, Muraenidae, Nemipteridae, Apogonidae, Balistidae, Labridae, Aulostomidae, Carangidae, Holocentridae, Pemoheridae, Pomachantidae, Siganidae, Tetraodontidae, and Zanclidae. The highest abundance of coral fish in Indonesian waters is found in the waters of the Karimunjawa National Park Conservation area with the highest abundance value of 14,850 ind/ha, namely from the Pomacentridae family with factors that influence the abundance of coral fish in Indonesian waters in the form of environmental conditions, coral reef cover values, substrate morphological characteristics, and community activities.

Kebakaran adalah bencana paling umum di Indonesia yang terjadi di rumah-rumah. Dalam beberapa situasi, pemilik rumah mungkin tidak menyadari kebakaran. Salah satu contohnya adalah jika kebakaran terjadi pada saat pemilik rumah tidak berada di rumah. Untuk menyelesaikan masalah ini, diperlukan sistem yang dapat memberi tahu pemilik rumah tentang gejala dini kebakaran. Selanjutnya, sistem pendeteksi kebakaran dini berbasis IoT dibangun dengan menggunakan bot WhatsApp untuk memberikan informasi. Metode prototipe digunakan untuk mengembangkan sistem. Hasil penelitian menunjukkan bahwa sistem deteksi kebakaran rumah yang menggunakan notifikasi WhatsApp berbasis IoT bekerja dengan baik dengan bagian yang digunakan. Sistem ini menggunakan sensor gas dan api untuk mendeteksi potensi kebakaran, dilengkapi dengan buzzer sebagai alarm suara dan fitur water pump untuk penanganan awal. Selain itu, sistem ini mengirimkan notifikasi otomatis melalui WhatsApp saat kondisi berbahaya terdeteksi.
