Abstract

This writing aims to analyze the distribution patterns and find out the affordability of the School's location to the settlements in the Batauga sub-district of South Buton Regency. The method used in this study is a quantitative descriptive method with Nearest Neighbor Analysis and baffer analysis. Data is obtained by survey and document review. The results showed 1) The pattern of distribution of School Locations in Batauga sub-district was calculated using the analysis of the nearest neighbor (Analysis Nearest Nigh) obtained T value = 0.26369, spatial pattern of School Location distribution in Batauga Subdistrict was Cluster pattern. 2). The results of Spatial Analysis using the Baffer function are the distribution of school locations in Batuaga Subdistrict, which have not fully served all villages in the subdistrict of Batauga. Educational facilities for junior high schools (SMP / MTs) are only able to serve 75%, namely Lawela Village, Lawela Seatan, Bandar Batauga, Busoa, Lakambau, Majapahit, Pogalampa, Mologina and Bola Village.

Abstract

The formulation of the problem in this study are: 1) What is the pattern of population settlements in Taliabu Barat Northwest District Taliabu District, 2) What are the factors that influence the population settlement patterns in Taliabu Northwest District Taliabu District. The purpose of this study is 1) To describe the population settlement patterns in Taliabu Northwest District, Taliabu Regency. 2) To find out the factors that influence the population settlement patterns in Taliabu Northwest District Taliabu District. This type of research is descriptive qualitative using a case study approach. Data collection techniques are observation, questionnaire, and documentation.Analysis of the pattern of settlement distribution was measured using the analysis of the nearest neighbor (nearest neighbor analysis), namely by calculating the size of the nearest neighbor parameter (T). Based on the results of the research on the Distribution Pattern of Population Settlements in Taliabu Northwest Subdistrict, Taliabu District, the pattern is uniform because the value of T ≥ 1.4 is the value of T = 2.54 m and patterned to follow the path or linear settlement pattern. Factors of settlement distribution patterns in Taliabu Northwest Subdistrict, Taliabu Regency are influenced by: First the community prefers to establish settlements in the coastal area of 67.3% and close to the road by 56.4%; The two of them mostly use their land as plantation land of 78.2% and agricultural land by 20%; The third source of water comes from the PDAM of 50.9% and is> 31 m at 54.5%; The four availability of natural resources mostly comes from agriculture / plantations, which is 96.4%.

Abstract

Beberapa tahun belakangan ini muncul berbagai isu-isu lingkungan tentang mangrove di Kabupaten Mamuju, seperti penyusutan lahan mangrove dibeberapa titik akibat alih fungsi lahan untuk kegiatan akuakultur. Tujuan penelitian ini adalah untuk: (1) menganalisis sebaran vegetasi mangrove di Kecamatan Kalukku; (2) menganalisis kondisi kesehatan vegetasi mangrove di Kecamatan Kalukku berdasarkan nilai normalized difference vegetation index (NDVI). Dalam penelitian ini dilakukan analisis citra Landsat 8 untuk memperoleh nilai NDVI dan pengumpulan data di lapangan. Hasil penelitian menunjukkan bahwa: (1) vegetasi magrove di Kecamatan Kalukku Kabupaten Mamuju tersebar sepanjang pantai wilayah ini dengan luas 82,2 ha dan Rhizophora mucronata merupakan jenis vegetasi mangrove yang mendominasi; (2) berdasarkan nilai NDVI pada citra Landsat 8 diperoleh rentang nilai NDVI dari -0,133 (terendah) hingga 0,414 (tertinggi). Sebagian besar kondisi vegetasi mangrove termasuk dalam kategori normal, yaitu seluas 78,19 ha (95,12%), sedangkan sisanya masuk dalam kategori buruk dan sangat buruk dengan luas masing-masing sebesar 3,12 ha (3,79%) dan 0,89 ha (1,08%). Hasil analisis korelasi antara nilai NDVI dengan tingkat kerapatan jenis mangrove sebesar 0,93 atau 93%. Hal ini menujukkan korelasi sangat kuat (0,80-1,00). Penelitian ini memiliki dampak yang signifikan dalam pengembangan kebijakan konservasi dan pengelolaan wilayah pesisir, serta meningkatkan kesadaran publik tentang pentingnya memelihara ekosistem mangrove.

Abstract

The application of the Normalized Difference Vegetation Index (NDVI) on multispectral satellite imagery has been extensively used to assess the quantitative and qualitative aspects of mangrove vegetation. However, the use of Sentinel-2 imagery for this purpose is still relatively new. This research aims to monitor the distribution and density of mangrove vegetation in West Sulawesi by implementing NDVI transformation on Sentinel-2 imagery. The mangrove forest in Mamuju Regency, located in West Sulawesi, is one of the rich areas of mangrove forests on the island of Sulawesi, Indonesia. However, this region also exhibits disturbances in the mangrove ecosystem, resulting in limited monitoring efforts. By utilizing NDVI transformation, we identified the distribution and density of mangrove vegetation using Sentinel-2 imagery. The accuracy of image classification was evaluated using the confusion matrix method, and further analysis was conducted using linear regression to test the relationship between NDVI and mangrove density values obtained from field surveys. The results indicate that the total area of the mangrove forest reaches 1,798 hectares distributed along the coastal areas in the districts of Sampaga, Papalang, Kalukku, Mamuju, Simboro, Tapalang Barat, and Tapalang. Nearly 60% of this area has high mangrove density, while approximately 7% to 9% falls into the low and lowest density categories. NDVI values range from 0.06 to 0.81, with the highest value found in the Mamuju District and the lowest in the Papalang District. The correlation between NDVI and mangrove density shows a strong positive relationship (R=0.78). Therefore, Sentinel-2 imagery demonstrates high accuracy and potential for the development of predictive models for mangrove vegetation density. These findings have significant implications for the development of conservation policies and environmental management, as well as raising public awareness of the importance of preserving mangrove forests.
