Abstract

The forest resources balance sheet prepared for the implementation of law no. 41 of 1999 ratified article 13 paragraph (4), in the technical process of implementation it always refers to the decision of the Minister of Forestry no. 6444/kpts-ll/1999 regarding instructions for preparing forest resource balance sheets. The forest resource balance sheet is information that describes forest resource reserves, loss and use of forest resources so that at a certain time the trend of surplus or deficit compared to the previous period can be seen. Law. 41 of 1999, article 13 paragraph 4. Remote sensing offers great potential for the development of methods for calculating the balance of forest resources and changes in the forest sector and geographic information systems (SIG) which are used to provide digital form and analysis of the earth's geographic surface so as to form precise and accurate spatial information. This research uses quantitative analysis. This research aims to determine changes in forestry stocks in the Gumanti Valley district, and knowledge about forest balance in the Gumanti Valley region. The results of research based on data show that around -12,708 ha of land in the form of secondary forest has experienced a reduction or deficit in area. Apart from that, other land that has experienced a reduction in area is primary forest. Meanwhile, the land that has experienced the most significant increase in area is in the form of fields covering an area of ​​+13,239 ha from 2017 to 2023.

Abstract

This research of aims are; 1) identify the Land Surface Temperature (LST) of land use using Landsat 8 OLI imagery for the Padang City area, 2) identify the distribution of land use using Landsat 8 OLI imagery for the Padang City area, 3) The effect of Land Surface Temperature (LST) on land use using Landsat 8 OLI imagery for the Padang City area. In obtaining the results of Land Use researchers used the Indonesian National Standard (SNI) 7645-2020 Classification of Land Cover Scale 1: 250,000. Meanwhile, to get the surface temperature value using the LST (Land Surface Temperature) method. The results of land use analysis obtained 10 classes, namely settlements, airports, mining, built-up land, settlements, fields, rice fields, shrubs and shrubs, secondary forests, and rivers. LST (Land Surface Temperature) results obtained 8 temperature classes including the lowest temperature, which is around 19.38ᵒC and the highest temperature 33.17ᵒC.

Abstract

The increase in population and urban development leads to higher energy consumption, which adversely affects environmental quality. The resulting impacts include a reduction in green open spaces, an increase in air pollution, and a rise in surface temperatures. This leads to the phenomenon known as the Urban Heat Island (UHI), where urban areas experience higher temperatures than their rural surroundings. This research aims to identify the UHI in Padang City using Landsat multitemporal data over a 5-year observation period from 2019 to 2023. The method involves converting digital numbers from Landsat 8 OLI/TIRS and Landsat 9 satellite images in the Thermal Band to generate Land Surface Temperature (LST) data. Subsequent processing is carried out in GIS software, such as QGIS or ArcGIS, to obtain the distribution of UHI. The research findings indicate fluctuations in land surface temperatures, with both increases and decreases observed over the study period. Each year witnesses an expansion of the UHI area, indicating worsening heat conditions in various regions of Padang City. The findings suggest that land surface temperatures will continue to rise with further urban expansion, highlighting the need for proactive measures. Therefore, it is crucial to develop and implement policies to control and mitigate the negative impacts of UHI in urban spatial planning.

Abstract

Land Surface Temperature (LST) is widely utilized in current studies, particularly as an initial survey tool to assess geothermal activity in locations suspected to have geothermal sources. The research method involves geometric correction of Sentinel-3 imagery and conversion of temperature units from Fahrenheit (F) to Celsius (C) to ensure accuracy in temperature measurement. Image data processing from Sentinel-3, including thermal band analysis, is carried out to generate land surface temperature values. The field-measured temperatures are then compared to the land surface temperature data obtained through processing. The temperatures in the location, ranging from 23°C to 35°C, fall within the minimum geothermal temperature range, indicating potential geothermal activity. However, the LST values from the image data exhibit some differences compared to the on-site measurements. These discrepancies are categorized into classes I (23.7 – 24°C), II (24 – 24.3°C), and III (24.3 – 24.8°C), marked by red areas in the LST values. These discrepancies are attributed to various factors during image recording and processing, such as atmospheric interference and sensor calibration.
