Tujuan dari penelitian ini adalah untuk mengetahui kondisi fisika kimia perairan, tutupan terumbu karang dan jenis karang yang hidup di titik pengamatan , laju pertumbuhan karang dan korelasi antara variabel fisika kimia perairan terhadap laju pertumbuhan terumbu karang. Metode penelitian menggunakan metode eksplanatif dan dianalisa menggunakan SPSS 23 dan Microsoft Excel 2013 . Hasil yang diperoleh adalah kualitas perairan di lokasi tersebut mendukung pertumbuhan ekosistem terumbu karang dengan suhu yang berkisar 27-30 0 C, kecerahan sampai dasar dan salinitas sebesar 35 ppm. Tutupan terumbu karang di titik pengamatan tergolong baik dengan persentase penutupan sebesar 61,92%. Jenis karang yang dominan adalah jenis Acropora formosa dan Acropora divaricata . Laju pertumbuhan karang yang diukur adalah jenis Acropora formosa dengan nilai sebesar 5,47 mm/bulan. Berdasarkan nilai R 2 pada grafik rata-rata laju pertumbuhan terumbu karang, waktu pengukuran memiliki pengaruh sebesar 95,1 % terhadap laju pertumbuhan karang. Hasil uji Pearson menunjukkan variabel fisika kimia perairan yang memiliki hubungan terhadap laju pertumbuhan terumbu karang adalah arus dan pasang surut air laut dengan nilai Sig. 0,027<0,05 dan Sig. 0,046<0,05.

Tourists are interested to visit Menjangan Kecil Island because the diversity, especially the coral reef ecosystem and its location that close to the main island. However, these tourism activities cause degradation of coral reef. The purpose of this study was to determine the physical chemistry of the waters, coral reef cover and the types of coral, the growth rate of coral and the correlation between the variables of physical chemistry of the waters on the growth rate of coral reefs. The research method used explanatory method and analyzed using SPSS 23 and Microsoft Excel 2013. The quality of water in these locations supported the growth of coral reef ecosystems with temperatures ranging from 27-30 0 C, brightness to base and salinity of 35 ppm. Coral reef cover at the observation point is classified as good with a closing percentage of 61.92%. The dominant coral species are Acropora formosa and Acropora divaricata. The measured coral growth rate was Acropora formosa with a value of 5.47 mm / month. Based on the R 2 value on the graph of the average growth rate of coral reefs, the measurement time has an influence on the growth rate of the coral. The results of Pearson's test showed that the physics of water chemistry variables that have a relationship to the growth rate of coral reefs are currents and tides with the value of Sig. 0.027 <0.05 and Sig. 0.046 <0.05.
