Putro, Sony Saksono (2017) Analisis Hubungan Fraksi Sedimen Vulkanik Terhadap Kerapatan Mangrove Di Pesisir Kelurahan Pilang, Kecamatan Kademangan, Kota Probolinggo. Sarjana thesis, Universitas Brawijaya.
Abstract
Ekosistem mangrove merupakan salah satu ekosistem langka dan khas di dunia, karena luasnya hanya 2% permukaan bumi. Tingkat kerusakan ekosistem mangrove dunia, termasuk Indonesia, sangat cepat dan dramatis.. Akhir-akhir ini yang paling terlihat memiliki dampak terhadap ekosistem mangrove adalah dampak yang ditimbulkan oleh lahar dingin erupsi Gunung Bromo. Aliran lahar dingin ini mengakibatkan rusaknya mangrove dan juga sedimentasi berlebih yang mengganggu sirkulasi pasang surut di daerah tersebut. Melihat permasalahan tersebut, maka upaya-upaya perlindungan pantai harus dilakukan untuk menghindari terjadinya pasang surut yang tidak normal karena sedimentasi yang sangat tinggi. Tujuan penelitian ini adalah untuk mengetahui kerapatan mangrove dan fraksi sedimen dan juga hubungan keduanya untuk penentuan kawasan konservasi. Pengambilan data meliputi data mangrove, fraksi sedimen, dan kualitas perairan. Analisa data menggunakan uji korelasi regresi linier sederhana. Terdapat 3 spesies mangrove yang ditemukan di Kelurahan Pilang yaitu Avicennia alba, Avicennia marina, dan Rhizophora mucronata. Kerapatan mangrove di Kelurahan Pilang sebesar 311 ind/ha tergolong kerapatan mangrove yang jarang. Fraksi pasir sangat mendominasi pada substrat kawasan mangrove sebesar 68.7%, kemudian fraksi lanau 24.4%, dan lempung 6.7%. Hubungan fraksi sedimen terhadap kerapatan mangrove memiliki nilai yang rendah, yaitu : pasir 0.35426 atau 35.43%, lanau 0.34756 atau 34.75%, dan lempung 0.35426 atau 35.43%.
English Abstract
Mangrove ecosystem is one of the rarest and most unique ecosystems in the world because of the extension of only 2% of the earth's surface. The rate of damage to the world's mangrove ecosystems – including Indonesia – is very fast and dramatic. Nowadays, the most visible impact on mangrove ecosystem is the impact caused by the cold lava eruption of Mount Bromo. This cold lava flow causes damages on mangrove plantation and also excessive sedimentation that disrupts the tidal circulation in the area. Judging from these problems, coastal protection efforts should be undertaken to avoid unusual tides due to high sedimentation. The purpose of this study was to determine the density of mangrove and sediment fractions as well as their relationship to the determination of conservation areas. Data collections included were mangrove data, sedimentary fraction, and water quality. Data analysis used in this study was simple linear regression test. There were 3 species of mangroves found in Pilang Village namely Avicennia alba, Avicennia marina, and Rhizophora mucronata. Mangrove density in Pilang Village for 311 ind /ha is rare mangrove density. Sand fraction was dominant in mangrove substrate with 68.7% percentage, followed by the fraction of silt with 24.4% percentage and clay with 6.7%. The relation of the sedimentary fraction to the mangrove density showed a low value, namely sand as much as 0.35426 or 35.43% followed by silt with 0.34756 or 34.75% and clay with 0.35426 or 35.43%.
