Abstract

Hutan mangrove di Pantai Timur Sidoarjo sebagian besar telah mengalami kerusakan yang disebabkan oleh rendahnya tingkat kesadaran masyarakat dan stakeholder lainnya dalam menjaga pelestarian dan fungsi serta manfaat hutan mangrove, sehingga diperlukan evaluasi zonasi hutan mangrove yang ada untuk memberikan informasi dan bahan pertimbangan dalam pengelolaan wilayah pesisir. Pelaksanaan evaluasi hutan mangrove dilakukan melalui kajian vegetasi mangrove, aspek peran serta masyarakat, kebijakan dan kelembagaan. Empat stasiun pengamatan diobservasi selama penelitian berlangsung guna menentukan zonasi, kekerapan, kerapatan, dominasi dan Index Nilai Penting vegetasi. Sebanyak 60 responden yang terdiri dari tokoh masyarakat, LSM dan Instansi terkait dilibatkan dalam survey sosial guna menentukan persepsi dan perilaku masyarakat terhadap hutan mangrove. Sedangkan dari segi kebijakan dikaji tugas dan fungsi lembaga yang berperan serta kebijakan yang berperan dalam pengelolaan hutan mangrove. Kondisi zonasi hutan mangrove yang ada mendekati kondisi alami, dijumpai di daerah muara sungai dan pesisir pantai yang relatif belum terganggu, sedangkan di daerah pertambakan dan budidaya (stasiun 3 dan 4) mengalami pengurangan jenis maupun kerapatannya. Jenis mangrove yang mendominasi adalah Avicennia sp. diikuti jenis Bruguiera sp., Rhizophora stylosa dan Sonneralia alba. Untuk menjaga dan meningkatkan fungsi hutan mangrove diperlukan peran serta masyarakat dan didukung oleh kebijakan dan kelembagaan yang jelas tugas dan kewenangannya.

Mangrove forests along the eastern coast of Sidoarjo have mostly been damaged due to a lack of public and stakeholder awareness regarding the sustainability, functions, and benefits of mangrove forests. Therefore, an evaluation of the existing condition of the mangrove forests is required to provide input for coastal area management. This study was conducted by evaluating the existing condition of mangrove vegetation, public involvement, and policy and institutional issues. Four stations were observed during the research to determine the composition, frequency, density, dominance, and Importance Value Index (IVI) of the vegetation. Approximately 60 respondents, comprising community leaders, NGOs, and representatives of relevant institutions, were surveyed to determine their perceptions and behaviors toward mangrove forests. From a policy perspective, the tasks and functions of the relevant institutions were evaluated using SWOT analysis. Natural mangrove forest formations at Stations 1 and 2 were found in relatively undisturbed estuarine and coastal areas, whereas the fishery zones at Stations 3 and 4 showed a reduced number of species and lower vegetation density. The dominant mangrove species was Avicennia sp., followed by Bruguiera sp., Rhizophora stylosa, and Sonneratia alba. To maintain and improve the functions of mangrove forests, public involvement is required and should be supported by institutions with clear policies, roles, and responsibilities.
