(Suci Laela Utami. 26040119120008. Indeks Kesehatan Mangrove Di Taman Nasional Karimunjawa. Rudhi Pribadi & Ibnu Pratikto).
Mangrove adalah tumbuhan yang mempunyai habitat di daerah pasang surut sehingga berkaitan dan berpengaruh terhadap ekosistem darat maupun lautan. Peran mangrove juga sangat penting terhadap ekologis,fisiologis dan ekonomis. Seiring perkembangan zaman ekosistem mangrove mengalamai degradasi baik disebabkan secara alami maupun aktivitas antropogenik. Untuk mengatasi hal tersebut maka dilakukan penilaian kondisi kesehatan mangrove. Mangrove Health Index merupakan suatau matrik yang menunjukan kualitas suatu ekosistem mangrove dengan indeks yang dapat diperbandingkan antara lokasi dan waktu yang berbeda. Tujuan penelitian ini adalah untuk mengetahui persentase Mangrove Health Index di kawasan ekosistem mangrove Pulau Karimunjawa yang dilakukan melalui pengukuran parameter komunitas mangrove seperti jumlah individu anakan (Nsp), diamater rata-rata batang (DBH) dan persentase tutupan kanopi (C). Metode penelitian
menggunakan metode deskripstif dan penentuan lokasi penelitian menggunakan meotde purposive random sampling. Perhitungan Mangrove Health Index (MHI) menggunakan persamaan parameter utama tutupan kanopi mangrove,kerapatan,dan diameter batang (DBH). Sampling tutupan kanopi mangrove dilakukan dengan metode hemispherical photography dengan menggunakan lensa fish eye yang diletakan pada kamera depan smartphone. Kerapatan dan diameter dihitung dan dimasukan datanya menggunakan aplikasi
MonMang. Hasil penelitian menunjukan Mangrove Health Index diperoleh dengan rentang nilai 52,45 – 75,85% dengan kategori secara umum adalah Excellent. Nilai persentase Mangrove Health Index di Taman Nasional Karimunjawa mempunyai nilai terendah pada stasiun JK yaitu sebesar 52,45% dan tertinggi pada stasiun LG yaitu sebesar 75,85%.

ABSTRACT
(Suci Laela Utami. 26040119120008. Mangrove Health Index in
Karimunjawa National Park. Rudhi Pribadi & Ibnu Pratikto).

Mangroves are plants that have habitats in tidal areas so that they affect terrestrial and marine ecosystems. Mangrove function is also very important to ecological, physiological and economical. Along with the times mangrove ecosystems experience degradation both natural causes and anthropogenic activities. To overcome this, an assessment of mangrove health conditions is carried out. Mangrove Health Index is a matrix that shows the quality of a mangrove ecosystem with an index that can be compared between different locations and times. The purpose of this study was to determine the Mangrove Health Index in the mangrove ecosystem area of Karimunjawa National Park conducted through
measurement of mangrove community parameters such as the number of individual saplings (Nsp), average stem diameter (DBH) and percentage of canopy cover (C). The research method uses descriptive methods and determination of research locations using purposive random sampling. Calculation of Mangrove Health Index (MHI) using the main parameter equation of mangrove canopy cover, density, and stem diameter (DBH). Sampling of mangrove canopy cover was carried out using the hemispherical photography method using a fish eye lens placed on the front camera of a smartphone. Density and diameter were calculated and data were entered using the MonMang application. The results showed that the Mangrove Health Index was obtained with a value range of 52.45 - 75.85% with the general category being Excellent. The percentage value of Mangrove Health Index in
Karimunjawa has the lowest value at JK station which is 52.45% and the highest at LG station which is 75.85%.
