Abstract

Mangroves are plants that live on beaches and river mouths, where these areas experience ups and downs of sea water. Around 3 million hectares of mangrove forest grow along 95,000 kilometers of Indonesia's coast, which is 23% of the world's total mangrove ecosystem. Indonesia's mangrove ecosystems are located in Papua, Kalimantan and Sumatra. This study aims to measure the distribution and density of mangrove forests in Tanah Bumbu Regency, South Kalimantan using Landsat 8 imagery with the support vector machine (SVM) classification method. Meanwhile, the density value was determined using the Normalized Difference Vegetation Index (NDVI) method. The results show that the mangrove distribution area is 2448.84 ha, of which the widest mangrove distribution is in the Simpang Empat area with an area of 1702.62 ha. Based on these results, it shows that the mangrove forest area in Tanah Bumbu Regency still has a fairly dense mangrove area.

Abstract

Land use is a form of the influence of human activities on part of the physical surface of the earth. Land use will increase if the population increases. Activities carried out by humans can be in the form of building settlements, plantations and agriculture and cannot be separated from spatial problems because they are related to land use. Research aims to identify the land use and create distribution maps of land use in the district of Central Kalimantan province Lamandau using Landsat Satellite Imagery 8 OLI/TIRS. The land use classification uses the maximum likelihood classification method. The result of this research is a map of land use distribution in Lamandau Regency which has an area of approximately 486,738 ha. The results of this study obtained 7 classes of land use in Lamandau Regency, namely forests with an area of 182,383 ha, shrubs 118,263 ha, oil palm plantations 74,666 ha, mixed gardens 51,117 ha, settlements 28,742 ha, agriculture 28,087 ha and rivers 3,480 ha.

Abstract

Aliran permukaan merupakan air yang mengalir di permukaan tanah dan merupakan curah hujan yang mengalir ke sungai atau saluran danau dan laut. Di daerah beriklim basah bentuk aliran yang mengalir dikenal sebagai aliran permukaan. Debit adalah laju aliran air (dalam bentuk volume air) yang melewati suatu penampang melintang sungai persatuan waktu. Penelitian ini dilakukan di Catchment Area Sungai Hauran karena dapat dikatakan sebagai daerah tangkapan air bagian hulu dari Sub Sub DAS Apukan, Sub DAS Banyu Hirang, DAS Maluka. Analisis Aliran permukaan dan debit puncak dapat menggunakan Agricultural Non Point Source Pollution Model (AGNPS). Pengolahan data menggunakan model AGNPS diperoleh nilai tertinggi aliran permukaan pada sebesar 7,366 mm. Nilai aliran permukaan yang tinggi terdapat pada daerah tangkapan hulu, hal ini di pengaruhi oleh tekstur tanah dan tutupan lahan pada area tersebut. Besar nilai debit puncak pada outlet keluaran model AGNPS sebesar 3,063 m3/s , sedangkan nilai debit puncak tertinggi yaitu sebesar 3,390 m3/s
