Abstract

Mining results in infertile soil, acidic pH and lack of nutrients. Reclamation activities are one way to restore the benefits of land to be better and more productive in solving this problem. Assessment of reclamation success has been carried out on 8 (eight) IUPs, one of which is PT. Amanah Anugerah Adi Mulia (PT. A3M) in Tanah Laut Regency, South Kalimantan Province. Status PT. A3M has entered the post-mining stage and has rehabilitated mining-affected areas through reclamation and revegetation on the inpit dump land which is divided into three areas, namely the AR-05 area of 3.26 ha of the 2011 Planting Year, the AR-07 area of 3.61 ha of the 2014 Planting Year and the AR-07 area of 3.27 ha of the 2017 Planting Year. Therefore, the purpose of this study is to analyze the status of revegetation success related to the growth and health of revegetated plants in PT. Amanah Anugerah Adi Mulia and identified the factors causing the non-success of revegetation related to the characteristics of post-mining revegetation land. The results of the revegetation analysis regarding the percentage of plant growth and health: the percentage of growth was 96% (2011), 100% (2014) and 100% (2017), with a success value of > 90% (successful category) and a percentage of plant health of 91.14% (2011), 99.2% (2014) and 89% (2017), with a plant health value of > 89% categorized as healthy (normal height, fresh leaves and not yellow).

Abstract

Various indicators of hotspot occurrence as a cause of forest and land fires (karhutla) in Banjar District are still difficult to determine due to limited information. The analysis of FFMC (Fine Fuel Moisture Code) and DC (Drought Code) as well as the monitoring of the number of hotspots aims to determine the level of risk of forest and land fire hazards and can be an early picture of future forest and land fire disasters in the Banjar District of South Kalimantan Province. The data processing process to obtain the FFMC and DC values and their relationship with the number of hotspots is to calculate the FFMC and DC values of station observations and model observations through the Microsoft Excel Add-In (FWI Add-in) program. The two models will then be verified with a scatter plot and through the Pearson correlation test the relationship between the FFMC and DC of the ERA5 model and the number of hotspots can be found. As a result, the FFMC and DC (station observation and model) showed extreme risk levels for the 2014, 2015 and 2018 forest and land fires. Both models show a positive and linear relationship on the scatter plot. And in the Pearson correlation test, both variables between the FFMC and DC of the ERA5 model and the number of hotspots are moderately to strongly correlated. This condition indicates that an increase in the risk level of forest and land fires will be followed by a significant increase in the incidence of forest and land fires in the Banjar Regency area of South Kalimantan Province.

Abstract

Sebangau National Park, in Central Kalimantan Province, is a wetland conservation area. In 2015, forest and land fires resulted in 455 hectares being burned. The identification of hotspots in this study is based on the number and distribution of hotspots based on satellite imagery data from the Moderate Resolution Imaging Spectroradiometer (MODIS) in 2001–2020. This study identifies hotspots by looking at the influence of rainfall and ENSO (El Nino Southern Oscillation) conditions. The method used is the method of spatial and temporal analysis. The aim of this study was to determine the characteristics of the hotspot distribution pattern in Sebangau National Park, Central Kalimantan Province, both spatially and temporally. There is a similarity between the temporal and spatial characteristics of hotspots in the number of significant additions to the number of hotspots in August, September, and October. The influence of monsoonal rainfall types and climates such as ENSO (El Nino Southern Oscillation) greatly influences the occurrence of hotspot events in Sebangau National Park, Central Kalimantan Province. The distribution pattern of hotspots in Sebangau National Park, Central Kalimantan Province, peaked in October, and the worst addition to the number of hotspots occurred in 2015, when these conditions occurred during the dry season and when the ENSO index (El Nino Southern Oscillation) showed +2.6, where these conditions included strong El Nino categories.

Abstract

South Kalimantan is one of the provinces in Indonesia which has a high risk of flood disasters seen from its physical condition, which geographically is mostly located below sea level. In 2021, 11 out of a total of 13 districts and cities in South Kalimantan were affected by flooding on a large scale, which caused tens of thousands of residents to suffer losses and even lost family members. IBFWS (Impact Base Forecast and Warning Services) is present as the latest innovation from the Meteorology, Climatology and Geophysics Agency as an impact-based weather forecast information service. To determine the accuracy of the IBFWS service information, it is necessary to validate the prediction results issued by IBFWS with the actual situation. By using spatial analysis methods, it is hoped that it can describe which areas are potentially affected by flooding and continued with the calculation of the contingency table so that the accuracy value of IBFWS is obtained in predicting areas potentially affected by flooding in South Kalimantan. IBFWS validation results in predicting areas potentially affected by flooding in South Kalimantan during the rainy season range between 0.85 – 1.00 which mean 85% - 100% the IBFWS prediction results are correct, during the transition season in general is 0.77 which mean 77% the IBFWS prediction results are correct, and during the dry season it ranges between 0.92 – 1.00 which mean 92% - 100% the IBFWS prediction results are correct.

Abstract

The white-fronted langur (Presbytis frontata) is categorised as a protected wildlife according to (P.106/MENLHK/SETJEN/KUM.1/8/2018). Forest degradation, land use change, and environmental damage due to human activities by encroaching on forests can cause habitat fragmentation. The preservation of white-fronted langurs may be threatened by degraded or unsuitable habitat conditions. This study aims to analyse the characteristics and components of white-fronted langur habitat and to analyse the suitability of white-fronted langur habitat in the Cantung watershed area of Kota Baru district, South Kalimantan. The research was conducted in September-October 2021. Data collection using the roaming method.This study concluded that there were 31 habitat distribution points with 72 individuals of white-fronted langurs observed. White-fronted langurs in the Cantung watershed area were found at an altitude of 5-85 m above sea level, optimal temperature of 20°-32°C, humidity of 78-95%, distance from water sources 200-500 m, distance from roads <200-600 m, locations with plantation land cover, dry land agriculture, mixed gardens and mining. The suitability of white-fronted langur habitat in the Cantung Watershed Area based on 6 habitat components shows the highest scoring value of 3 (high level of suitability).
