Abstract

This research is motivated by the rapid growth and development of infrastructure and tourism in North Toraja Regency. This has an impact on the closure of green land or vegetation areas and a decrease in environmental quality. Vegetation is a collection of several types of plants that grow together in one place to form a unity where individuals depend on each other. Vegetation has a major influence on all aspects of life, one of which is changes in forest land cover. If the vegetation has a low level of density, it will cause a reduction in forest litter, because there is no longer any part of forest vegetation on the land. Based on this information, it is necessary to conduct research on the level of vegetation density in North Toraja as a reference to see the condition of vegetation density and changes in vegetation density. The Normalized Difference Vegetation Index (NDVI) and Soil Adjusted Vegetation Index (SAVI) algorithms are applied to Landsat 8 imagery. Then the data is processed using GIS software. Based on the NDVI algorithm, the vegetation density that decreased in the high-medium class was 11,484.32 Ha; high-low 2,718.90 Ha; medium-low 7,107.67 Ha; and there was an increase in the low-medium class of 4,741.15 Ha; low-high 1,090.48 Ha; and medium-high 16,540.27 Ha. Meanwhile, based on the SAVI algorithm, vegetation density decreased in the high-medium class 11,484.31 Ha; high-low 3,791.33 Ha; medium-low 1,121.40 Ha; and there was an increase in the low-medium class 1,428.21 Ha; low-high 2,055.49; and medium-high 2,762.21 Ha.

Abstract

This research is motivated by the relocation of the capital city from DKI Jakarta Province to East Kalimantan Province, specifically in the Sepaku Sub-district, Penajam Paser Utara Regency. The relocation of the capital city may lead to changes in land cover due to land conversion and development activities. The purpose of this study is to analyze changes in land cover in the Sepaku Sub-district, Penajam Paser Utara Regency, based on mapping using the supervised classification method with Landsat 8-9 imagery from 2014 and 2024. The results of land cover identification in the Sepaku Sub-district classify the area into vegetated areas (agriculture), vegetated areas (non-agriculture), open land, settlement and related land, and water bodies. In 2014, land cover in Sepaku Sub-district was dominated by non-agricultural vegetated areas, accounting for 60.04% of the total area, which slightly increased to 60.21% in 2024. Furthermore, the results show a slight increase in non-agricultural vegetated areas, from 75,804.1 hectares in 2014 to 76,013 hectares in 2024. Conversely, a decrease was observed in agricultural vegetated areas and open land types. The area of agricultural vegetated land decreased from 39,663 hectares in 2014 to 38,271 hectares in 2024, while open land decreased from 7,111 hectares in 2014 to 6,141.2 hectares in 2024. Meanwhile, settlement and related land cover experienced a significant increase, growing from 2,454 hectares in 2014 to 4,520.2 hectares in 2024.

Abstract

This research is motivated by the fact that currently remote sensing technology continues to develop, both in terms of data collection and processing. This is characterized by the existence of data collection techniques using unmanned aerial vehicles for aerial photo mapping. The advantage of using this technology is that it is effective and efficient both in terms of time and human resources for mapping in areas that are not too large. Another advantage is that it can produce clearer photos, because the plane's flying height is below 400 meters above ground level so that during the shooting process there is no cloud interference. The aim of this research is to create an aerial photo map at the Samarinda State Agricultural Polytechnic, validate objects in aerial photos and in the field, and provide information about the area, boundaries and topography of the Samarinda State Agricultural Polytechnic campus area. The implementation of activities and research objects is the Samarinda State Agricultural Polytechnic campus area. This research uses a small format aerial photo mapping method using a Quadcopter, making it easier to determine where to start taking off and landing. With a Quadcopter vehicle, grounding problems are no longer an obstacle. The research results showed that photography carried out with a Quadcopter at a height of 200 m above the ground produced an area of 28.17 Ha and a spatial resolution of 8.40 cm/pixel. The validation results in aerial photos and in the field using drones have a small difference between 0-4 cm with an average of 1.625 cm/photo. From the digitization results of campus objects, there are 30 objects on campus with a total area of 2.67 Ha. As for the topography results in the campus area, the highest point is 107.5 meters above sea level and the lowest point is 60 meters above sea level.

Abstract

The relocation of Indonesia's capital from Jakarta to Nusantara in East Kalimantan Province has significantly affected land use, particularly in forests and agricultural resources. This study examines the spatiotemporal dynamics of land cover in the forestry and agricultural sectors within Kutai Kartanegara Regency of East Kalimantan Province. The goal is to support the smart forest city concept and enhance food sources within Ibu Kota Nusantara (IKN). Data related to geographical (location) and temporal (time) were analyzed using Geographic Information System (GIS) tools, enabling the mapping, overlaying, and analyzing spatial data over time. The findings show that Kutai Kartanegara has 30% forested areas and 7% agricultural land. There are eight districts with dryland forests, seven with mangrove forests, and fourteen with swamp forests. The study identifies fourteen districts nominated for dryland agriculture, nine for rice fields, and seven for aquaculture. However, forest cover in both drylands and wetlands has been declining annually. Additionally, the study pinpointed potential areas for urban forest development in Tabang District and locations for food production in Anggana, Samboja, and Muara Badak. The findings provide actionable insights for policymakers to optimize land allocation, ensuring sustainable resource management in the evolving ecosystems of the new capital.

Abstract

Ekosistem hutan hujan tropis merupakan sumber kehidupan dan penghidupan bagi masyarakat Kalimantan Timur. Sayangnya keberadaan hutan di Kalimantan Timur sering hanya dilihat dalam perspektif ekonomi saja. Untuk itu perlu adanya studi untuk mengetahui nilai manfaat jasa ekosistem yang dimiliki oleh hutan tropis di Kalimantan Timur secara menyeluruh bukan hanya aspek ekonomi saja, tetapi juga aspek ekologis dan sosial. Dengan tujuan itulah, penelitian ini dilakukan. Metode valuasi yang digunakan adalah metode benefit transfer dengan memanfaatkan database valuasi jasa ekosistem TEEB (The Economics of Ecosystems and Biodiversity), serta data luasan hutan Kalimantan Timur. Hasil penelitian ini menunjukkan bahwa nilai total ekonomi (Total Economic Value/TEV) ekosistem hutan tropis di Kalimantan Timur adalah sebesar 90.806.238.765 USD/tahun. Nilai TEV tersebut mencakup nilai manfaat jasa pendukung sebesar 0,24%, jasa penyediaan sebesar 45,11%, jasa pengaturan sebesar 17,31%, dan jasa kultural sebesar 37,34%.
