Abstract

Protected a whose existence is protected because it is useful in maintaining the ecosystem. De jure land in the Liang Anggang protected forest area is state-owned land, but de facto is used, controlled and even owned by the community with land titles, until now there is no latest data regarding the status of land tenure (tenure) and community settlements  that exist in the Liang Anggang protected forest, so the problem raised in this study is how the status of land ownership is controlled by the community in the Liang Anggang protected forest land tenure boundaries take an inventory  the existing tenure status in the Liang Anggang Protected Forest Area. The method used is descriptive method, which aims to describe the object of research or research results, the data analysis used is spatial analysis, land tenure boundary data is analyzed using image overlays, land tenure status data is analyzed by tabulation and for the presentation of inventory data is in the form of maps and Tables. Most of the Protected Forest area has been controlled by the community since decades ago and the community said that they had obtained the land from generation to generation and part of the proceeds came from buying and selling. Based on the field survey, the land controlled by the community is 19.25 ha. The status of land tenure cultivated by the community does not have a certificate but there are some who hold cultivation permits issued by the RT, namely 15 lands, in the form of SKT issued by the Kelurahan as many as 6 lands and having cultivation permits from the Social Forestry Decree as many as 14 landsHutan lindung adalah hutan yang dilindungi keberadaannya karena bermanfaat dalam menjaga ekosistem. Secara de jure adalah milik negara, tetapi secara de facto dimanfaatkan, dikuasai bahkan dimiliki oleh masyarakat dengan adanya surat-surat tanah, sampai saat ini belum adanya data terbaru mengenai status penguasaan lahan (tenurial) dan pemukiman masyarakat yang ada di hutan lindung liang anggang, sehingga masalah yang dikemukakan dalam penelitian ini adalah bagaimana status kepemilikan lahan yang dikuasai oleh masyarakat dalam hutan lindung Liang Anggang. Tujuan dari Penelitian ini adalah mengidentifikasi batas-batas penguasaan lahan dan menginventarisasi status penguasaan lahan. Metode yang digunakan adalah metode deskriptif yaitu bertujuan untuk mendeskripsikan objek penelitian ataupun hasil penelitian, analisis data yang digunakan yaitu analisis spasial, data batas penguasaan lahan dianalisis menggunakan overlay citra, data status penguasaan lahan dianalisis dengan tabulasi dan untuk penyajian data hasil inventarisasi adalah dalam bentuk Peta dan Tabel. Kawasan Hutan Lindung sebagian besar telah dikuasai oleh masyarakat sejak puluhan tahun lalu dan masyarakat menyampaikan bahwa mereka mendapatkan lahan tersebut secara turun temurun dan sebagian hadil dari jual beli. Berdasarkan survey lapangan lahan yang dikuasai masyarakat adalah seluas 19,25 ha. Status penguasaan lahan yang digarap oleh masyarakat tidak memiliki sertifikat namun ada beberapa yang memegang izin garap yang dikeluarkan oleh RT yaitu 15 lahan, berupa SKT yang dikeluarkan oleh Kelurahan sebanyak 6 lahan dan memiliki izin garap dari SK Perhutanan Sosial sebanyak 14 lahan

Abstract

The level of vegetation density is one of the indicators of the value of soil surface moisture. However, monitoring the condition of vegetation and soil surface moisture quickly and thoroughly will be very difficult if only conventional methods are used. Remote sensing is one of the solutions for monitoring very large forest areas and can be used to find out information about very complex forestry problems using data from satellite imagery. The purpose of this study was to determine the distribution of moisture in KHDTK ULM, analyze the value of soil surface moisture at various levels of vegetation density and the correlation between humidity and vegetation density in the KHDTK ULM Area of Mandiangin Village. This study utilized the vegetation index using the EVI algorithm and the humidity index using the NDMI algorithm. The data presented is in the form of information about how much influence the vegetation index value (EVI) has on moisture conditions in the study area. The results of the data analysis showed that the EVI value was positively correlated with the soil surface moisture value. Regression analysis of the two variables resulted in the equation Y= 21.8936 + 97.3197X with a coefficient of determination (R2) value of 0.5451 or 54.51%. The coefficient of determination of 54.51% means that EVI has an effect of this value in affecting surface soil inertia. The correlation coefficient (r) of 0.738 shows a strong relationship between EVI value and humidity.Tingkat kerapatan vegetasi merupakan salah satu indikator nilai kelembaban permukaan tanah. Akan tetapi pemantauan kondisi vegetasi dan kelembaban permukaan tanah secara cepat dan menyeluruh akan sangat sulit dilakukan apabila hanya menggunakan metode konvensional. Salah satu solusi untuk pemantauan kawasan hutan yang sangat luas adalah menggunakan metode penginderaan jauh dengan untuk mengetahui informasi mengenai permasalahan kehutanan yang sangat kompleks menggunakan data dari citra satelit. Tujuan dari penelitian ini yaitu untuk mengetahui sebaran kelembaban di KHDTK ULM, menganalisis nilai kelembaban permukaan tanah pada berbagai tingkat kerapatan vegetasi serta korelasi antara kelembaban dan kerapatan vegetasi di Wilayah KHDTK ULM Desa Mandiangin. Penelitian ini memanfaatkan indeks vegetasi menggunakan algoritma EVI dan indeks kelembaban menggunakan algoritma NDMI. Data yang disajikan berupa informasi mengenai seberapa besar pengaruh nilai indeks vegetasi (EVI) terhadap kondisi kelembaban pada wilayah penelitian. Hasil analisis data menujukan bahwa nilai EVI berkorelasi positif dengan nilai kelembaban permukaan tanah. Analisis regresi dari kedua variabel tersebut menghasilakn persamaan Y= 21.8936 + 97.3197X dengan nilai koefisien determinasi (R2) sebesar 0.5451 atau sebesar 54.51%. Koefesien determinasi sebesar 54.51% mengartikan bahwa EVI berpengaruh sebesar nilai tersebut dalam mempengaruhi kelembaan tanah permukaan. Koefesien korelasi (r) yang bernilai 0,738 menunjukan hubungan yang kuat antara nilai EVI dengan kelembaban.

Abstract

The Forest Area with a Special Purpose of Lambung Mangkurat University has an area of approximately 2000 Ha, divided into 2 areas, namely Bukit Babaris and Bukit Waringin. Identification of changes in land cover and vegetation density has never been carried out, especially in the Babaris mountain area (1,617 hectares). This study aims to compare the results of the accuracy of the Maximum Likelihood Classification (MLC) method with the Normalized Different Vegetation Index (NDVI) method in identifying vegetation density from 2018 to 2022. The results of the accuracy test for the vegetation density method using the confusion matrix show that the Overall Accuracy value of the MLC method is low lower, namely 92.5%, and the NDVI method 93.75%. It can be concluded that the NDVI method is more sensitive in detecting vegetation than the MLC method. Factors that affect the inaccuracy of the MLC method depend on the accuracy and the number of class class training samples taken. Based on the results of the interpretation of density changes from the two methods, from 2018 to 2022 the area of vegetation classes tends to increase and looks fluctuating. The area of change in vegetation density in the MLC method of the non-vegetation classification class is relatively stable at over 9 ha/year, although the classification class rarely dominates over the year. Changes in the density of non-vegetation class vegetation in the NDVI method tend to decrease significantly in 2020 and 2021. Based on the two most accurate methods obtained by the NDVI method, that there is an increase in vegetation density in the KHDTK ULM area of the Babaris hill.
