Abstract

Kondisi ekosistem pesisir Kabupaten Pangandaran, sepanjang 28 kmmengalami kerusakan terutama pasca tsunami tahun 2006 mulai dari Pananjung hingga Parigi, kecuali Cagar Alam Pananjung yang masih terjaga kelestariannya. Oleh karena itu, diperlukan konsep terintegrasi yang memperhatikan aspek sosial, ekonomi, dan ekologi untuk mengatasi masalah tersebut. Penelitian ini meliputi wilayah pesisir Kabupaten Pangandaran. Penelitian ini bertujuan untuk mengetahui laju perubahan luasan greenbelt untuk mitigasi bencana tsunami yang terjadi di pesisir Kabupaten Pangandaran menggunakan data citra landsat tahun 1999, 2003, 2010 dan 2013. Metode yang digunakan dengan analisa supervised classification dengan interpretasi Citra Landsat. Hasilnya menunjukkan bahwa sejak tahun 1999 hingga 2013, kondisi greenbelt di pesisir Kabupaten Pangandaran mengalami perubahan. Greenbelt tahun 1999 memiliki luasan sekitar 133,56 Ha dan turun sekitar 40% pada tahun 2003 menjadi hanya 81,27 Ha. Pengrusakan hutan diakibatkan oleh aktifitas illegal logging dan pembukaan lahan untuk keperluan perkebunan, tambak dan aktifitas ekonomi lainnya. Setelah kejadian tsunami pada tahun 2006, proyek penanaman kembali greenbelt mulai digalakan pada tahun 2007/2008 dan hasilnya terlihat pada peningkatan luasan greenbelt menjadi 128,82 Ha atau naik sekitar 68% dibandingkan keadaan pada tahun 2003. Namun, pada tahun 2013 atau tepatnya 6 tahun pasca tsunami 2006, jumlah luasan hutan pantai kembali berkurang sekitar 4% menjadi 120,51 Ha. Kata Kunci : Citra Landsat, Greenbelt, Pangandaran

Abstract

Perairan Teluk Banten merupakan wilayah yang sibuk dengan aktivitas wisata bahari, industri, permukiman dan lain-lain. Kondisi tersebut dapat menimbulkan dampak-dampak negatif seperti pencemaran, erosi, dan masalah lingkungan lainya. Pemahaman mengenai kondisi hidro-oseanografi sangat penting sebagai langkah untuk pengelolaan dan perlindungan wilayah pesisir dan laut. Tujuan dari penelitian ini untuk mengetahui karakteristik hidrodinamika di Perairan Teluk Banten pada musim peralihan (Agustus - September) berdasarkan data primer (data satu bulan arus, pasang surut, suhu) dan data sekunder (batimetri, kualitas air dan nutrient). Simulasi model diolah menggunakan MIKE 21, didukung dengan penggunaan CD-Oceanography. Hasil pengolahan data menunjukkan bahwa pola arus di Perairan Teluk Banten didominasi arus pasut dengan kecepatan berkisar antara 0-0,41 m.s-1, ditunjukkan oleh hasil pengolahan dalam bentuk stick diagram dan scatter plot yang menunjukkan pergerakan arus cenderung teratur dan arah arus dominan menuju ke arah Tenggara dan Selatan, hal ini juga didukung dengan hasil Current rose dengan menggunakan software WR plot. Kecepatan arus di permukaan lebih besar dan menyebar dibanding kecepatan arus di dekat dasar perairan. Simulasi arus permukaan (nilai error MRSE 12,25 %) menunjukkan bahwa arus bergerak sesuai dengan pengaruh pasang dan surut dengan kecepatan berkisar antara 0-0,42 m.s-1. Simulasi juga memperlihatkan distribusi konsentrasi nutrient dan kualitas perairan dipengaruhi oleh karakteristik hidrodinamika Teluk Banten.

Abstract

Secara garis besar, morfologi pesisir timur laut Bali dikategorikan sebagai “Mountainous Coast" yaitu pesisir yang terbentuk dari aktivitas gunung api Tersier-Resen dari gunung Agung (3.142 mdpl). Sungai-sungai yang bermuara umumnya bersifat sub radial karena pengaruh gelombang dan arus laut lebih dominan dari arus sungai, maka beberapa sungai mengalir sejajar dengan garis pantai (spit) sebelum bermuara ke laut. Pengaruh endapan sungai dan gunung api menyebabkan pesisir timur laut Bali memiliki sedimen pasir hitam, kerakal dan bongkah yang terbentuk oleh proses-proses vulkanik. Adapun tujuan penelitian ini adalah untuk mengetahui zona wilayah pesisir yang rentan terhadap perubahan iklim di timur laut Bali. Metode penelitian yang digunakan yaitu dengan Indeks Kerentanan Pesisir (IKP) dimana data-data yang digunakan terdiri dari data geospasial dan data oseanografi yang diolah menjadi angka-angka secara kuantitatif. Hasil analisa data penelitian menunjukkan, pesisir timur laut Bali dikategorikan sebagai wilayah dengan kerentanan pesisir sedang – sangat tinggi, dimana dari 20 titik pengamatan dengan panjang garis pantai ± 60 km memperlihatkan hasil IKP untuk Profil 3 dan 9 memiliki kerentanan sangat tinggi ( > 4), sedangkan untuk Profil 1, 2, 4, 5, 6, 7, 8, 11, 12, 13, 14, 16, 17, 18, 19, dan 20 memiliki kerentanan tinggi (3 – 4), dan Profil 10, 15 memiliki kerentanan sedang (2 – 3).Kata kunci: kerentanan pesisir, perubahan iklim, timur laut BaliABSTRACTIn general, morphology of the northeastern coast of Bali is categorized as "Mountainous Coast" which is a coastal that was formed by volcanic activity Tersier-Resen from Mount Agung (3.142 mdpl).The rivers that empties to the sea generally in a sub radial form due to the influence of waves and ocean currents are more dominant than the rivers, hence several rivers flowi parallelly toward the coastline (spit) before emptying into the sea. Effect of stream sediment and volcanic cause the northeastern coastal Bali contains black sand sediment, gravel and boulders were formed by volcanic processes. The purpose of this study was to determine the coastal zone areas in the Northeastern Bali that are vulnerable to climate change. The method used was a Coastal Vulnerability Index (CVI) where the data used consisted of geospatial and oceanographic data that were processed into quantitative figures. Results of analyses shows that the northeastern coastal Bali categorized as coastal regions with moderate to very high vulnerability. Among the 20 observation points along ± 60 kms coastline,the CVI in Profile 3 and 9 show a very high vulnerability (> 4), while CVI at Profile 1, 2, 4, 5, 6, 7, 8, 11, 12, 13, 14, 16, 17, 18, 19 and 20 show high vulnerability (3 – 4), and CVI at Profile 10, 15 show moderate vulnerabilities (2 – 3).Keywords: Coastal Vulnerability, Climate Change, Northeastern Bal

Abstract

According to the Hazard Vulnerability Index from BNPB, Indonesia’s National Disaster Management Authority, West Pasaman Regency is one of the area with high vulnerability index located in West Sumatra Province, where all of its coastal areas are adjacent with The Indian Ocean. Coastal erosion and extreme waves have been reported to be the most prominent hazards, beside anthropogenic factors, along West Pasaman coastal area. This research was conducted to estimate the loss of shoreline in the area, and how far it has been shifted over the years. Thus, to achieve the objective, the dynamic of shorelines from different time scales was analyzed using quantitative data (satellite images, Netherland Map of Indonesia, and Indonesia topography map), and the statistical output of DSAS (Digital Shoreline Analysis System). The results were validated by a field survey in 2011 and interviewed local people in 2015. We found the highest erosion, about 8.44 m/y, has been occurring in Sasak Ranah Pasisie District, which separate 14 Km from where the highest accretion, about 23.7 m/y, in Kinali District took place.

Abstract

Marine sand mining activities in Lontar Village have been started legally since 2003 and temporarily halted in 2013. The locals blamed the activities for severe environmental destruction in almost every corner of the village such as low productivity ofaquaculture, coastal erosion, and habitat loss. This paper has an objective to provide preliminary data and analyses for environmental impact assessment of marine sand mining in Serang (Lontar Village). Field investigations were carried out in June 2014 to collect primary data such as bathymetrical data and water quality parameters in the region to understand the environmental conditions after 10 years of marine sand mining activities as well as the characteristicsof local oceanography. Extensive interview with the locals were also conducted to collect information about the socio-economic conditions of the village. Field findings showed that LontarVillage have experienced critical environmental problems such as coastal erosion, high turbidiy and loss of marine lives. Moreover, we also found that the abandoned aquaculture fields have also been converted as sand mining quarries. Recommendations to reduce further environmental damage in Lontar Village are proposed considering both socio-economy and physical aspects.
