Abstract

Ekosistem mangrove di pesisir Desa Pagatan Besar telah berkembang menjadi kawasan ekowisata mangrove yang membentang sepanjang 1 km di Pesisir Barat Desa Pagatan Besar. Desa Pagatan Besar dengan berbagai dinamika biofisiknya mempunyai potensi terjadinya perubahan bentang alam, yang umumnya dipengaruhi oleh gelombang dari Laut Jawa. Penelitian ini secara umum bertujuan (1) menganalisis riwayat gelombang maksimum 21 tahun, (2) menganalisis arus rata-rata selama 4 tahun terakhir, (3) mengamati pengaruh dinamika oseanografi terhadap perubahan garis pantai dan tutupan mangrove. Metode penelitian meliputi penelusuran literatur, pengumpulan data, pengolahan dan analisis data. Data gelombang diperoleh dari peramalan gelombang menggunakan data angin dari situs ECMWF dianalisis dengan plot series dan wave rose. Data arus diolah dengan metode least square pada software WTWC MATLAB untuk mengetahui pola distribusi arus total, pasang surut, dan residu setiap komponen arus. Analisis terhadap perubahan garis pantai dan tutupan mangrove menggunakan tumpang susun citra satelit Landsat tahun 1999, 2009 dan 2019. Hasil penelitian ini adalah (1) gelombang maksimum selama 21 tahun dominan terjadi pada Musim Barat (Desember – Februari) dengan ketinggian rata-rata 1,515 meter. Gelombang maksimum tertinggi terjadi pada tahun 2001 yaitu 2,03 meter, (2) Rata-rata kecepatan arus total pada Musim Barat mencapai 14,91 cm/s, arus pasut sebesar 13,88 cm/s dan arus residu sebesar 6,17 cm/s, dengan pola dominan ke arah timur laut dan tenggara, (3) Terjadi perubahan garis pantai (sedimentasi dan abrasi) serta penurunan luasan mangrove sebesar 4,68 Ha selama periode 1999 – 2009.

Abstract

This study examines the effectiveness of mangroves in long distances to the beach in the Mangrove ecotourism area of ​​Pagatan Besar Village. This study aims to determine the effectiveness of mangroves against extreme waves based on wave transformation before and after passing through mangrove vegetation. Data collection methods used are field research, literature and secondary data. The study was conducted by modeling the CMS Wave – SMS structure which predicts changes in height and deflection of extreme waves during the highest tide (Highest Astronomic Tide / HAT) that interacts with mangrove vegetation as a natural beach. The results obtained show that at stations overgrown with mangroves, the waves tend to be still high when approaching the mainland. This is different from Stations 2 and 3 which are overgrown with mangroves. The waves tend to decrease before approaching land. In Profile 1 (not overgrown with mangroves) and Profile 3 (covered with thin mangroves) the wave height is 75 meters from the shoreline (in front of the mangroves) the wave height is 0.31 m and at the back of the mangrove is still 0.01 m on the beach and the back of the mangroves. As for profile 2 (wide mangrove beach) at a distance of 150 m from the shoreline, the wave height has decreased to 0.26 m at the back of the mangrove. The wave height continues to decrease to 0.00 m or has run out.

Abstract

The Covid-19 pandemic has made all activities carried out online so that technological advances are the focus of development. The purpose of the service is to find out the Coordinate Retrieval Information System Using Google Map for Fire Mapping in Wetlands. The methodology used to use and utilize this application system is the Waterfall Model. Socialization and Training of Android-Based Applications is based on a geographic information system to view and find out the position of a location, for example the location of a settlement in a wetland area that has a high potential for disaster. The stages carried out in this service activity are the preparation stage and the stage of taking coordinates.

Abstract

Abstrak Amplang merupakan sejenis kerupuk yang selama ini dikenal sebagai cemilan khas dari Kalimantan dari bahan dasar olahan ikan tenggiri. Kelor adalah sumber vitamin dan mineral yang baik untuk tubuh.  Kelor juga kaya akan antioksidan yang berfungsi untuk melindungi tubuh dari radikal bebas. Tujuan dari kegiatan ini adalah mentransfer pengetahuan dan keterampilan teknis mengenai pengolahan hasil perikanan yaitu amplang ikan tenggiri yang gizinya tinggi dengan penambahan daun kelor sebagai kandungan antioksidan alami sebagai inovasi produk. Metode pelaksanaan kegiatan adalah metode observasi, penyuluhan dan diskusi, pelatihan dan demonstrasi, evaluasi dan pendampingan terhadap kelompok mitra poklahsar. Hasil kegiatan ini adalah bertambahnya pengetahuan mitra tentang kandungan dan khasiat daun kelor, meningkatnya keterampilan teknis dalam pengolahan hasil perikanan, terciptanya produk inovasi amplang ikan tenggiri yang mengandung daun kelor sebagai antioksidan alam, serta tingginya minat dan antusiasme mitra untuk menerapkan dan memasarkan produk ini sebagai variasi rasa amplang yang sudah ada sebelumnya. Kata kunci: amplang, ikan tenggiri, daun kelor, inovasi produk, desa tabanio

Abstract

Mangrove is a forest that grows on the coast, generally found in protected estuaries, river banks, and lagoons in subtropical and tropical regions. Mangroves describe ecosystems and plant families that can adapt to an environment influenced by tides. The condition of the mangroves in Bunati Village is quite apprehensive due to the conversion of mangrove land to other land uses such as oil palm plantations, industrial mining excavations, and others, seen from Google Earth images for 2013 and 2022, causing mangrove land cover in Bunati Village to decrease. Therefore it is necessary to analyze changes in land cover and the total area of mangrove damage for ten years from 2012 to 2022 in Bunati Village, Angsana District, Tanah Bumbu Regency, South Kalimantan Province. This study uses Sentinel 2 Satellite Image data for 2022, SPOT 7 for 2017, and SPOT 4 for 2012. The data analysis carried out is overlay. Changes in land cover in 2012 and 2022 in Bunati Village, namely mangrove land remaining to become mangroves covering an area of 73.48 hectares with a percentage of 39.88%, mangroves to non-mangrove 108.99 hectares with a percentage of 59.00%, mangroves to waters 2.05 hectares with a percentage of 1.12%, non-mangrove to mangrove 29.84 hectares with a percentage of 2.81%, non-mangrove to remain non-mangrove 1029.27 hectares with a percentage of 97.02%, non-mangrove to waters 1.79 hectares with a percentage 0.17%, waters turned into mangroves 6.67 hectares with a percentage of 47.14%, waters turned non-mangrove 5.43 hectares with a percentage of 38.35%, and waters turned into waters 2.21 hectares with a percentage of 14.51%. The total area of mangroves that have suffered damage or shrinkage is 74.74 hectares.
