Abstract

Currently, one of the main problems in the agricultural industry is the conversion of irrigated rice fields. The potential for irrigated rice fields in Bandung Regency is needed to help overcome agricultural problems. This study aims to find out how to analyze the potential index of irrigated rice fields and land that is not rice fields but in Bandung Regency by mapping the potential index of rice fields using the Geographic Information System. The GIS analysis used was using scoring and overlay on the parameters used. The results of the overlay of each parameter produced an index of irrigated rice field potential which showed that rice fields in Bandung Regency were most planted on land that had IPL with a medium class, which was 697.99 Km² with a percentage of 39%. Land that is not a rice field and has the potential to become a new rice field is 5 classes, namely very high with an area of 42.34 Km2 consisting of 12 sub-districts, land with a high category has an area of 321.44 Km² consisting of 14 sub-district areas, in the medium potential class, which is the most dominating Bandung Regency, which is 633.79 Km2 which covers 20 sub- district areas, the distribution of low-class potential land covers 24 sub-districts covering an area of 355.36 Km2, while in the very low land potential class spread across 20 sub-districts covering an area of 98.21 Km2. As a recommendation, rice fields with high potential should be maintained as rice fields, and rice fields with low potential should be processed more optimally.

Abstract

Forest and land fires often occur in the Lamandau Regency area, Central Kalimantan, which causes forest function to no longer be optimal due to forest and land fire disasters which continuously occur every year. This research aims to determine the severity of forest and land fires that occurred in Lamandau Regency in 2021 and 2022. The method used in this research is the Normalized Burned Ratio (NBR). The results of the research include mapping the severity of forest and land fires in 2021-2022 in Lamandau Regency. In 2021, the area affected by forest fires reached 151,750 hectares, 48 hectares in the very severe category, 2,156 hectares in the severe category. There will be a decrease in 2022 with an area affected by forest and land fires of 40,982 hectares, a reduction of more than 50% from 2021. The area of very badly burned areas has decreased, to 0.08 hectares. Meanwhile, the area of severely burned areas experienced a significant decrease, reaching 207 hectares. The land use affected in 2022 is forest of 82,284 hectares, plantations of 53,921 hectares. Other land uses such as open land and settlements do not have a large enough impact with an affected area of 1000 hectares. The worst affected land use in 2022 will be forests covering an area of 27,284 hectares, plantations covering an area of 10,361 hectares. However, in the use of residential land and built-up land as well as open land, the area burned has increased by 1000 hectares. This study shows a decrease in the severity of forest and land fires that occurred in 2021 and 2022.
