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

Gold miners use mercury for the gold extraction process, and annually releases no less than 1,000 tons of hazardous materials into the environment. The mercury content in the Kahayan watershed reaches 2,996 - 4,687 g/l and this value exceeds the standard limit for mercury content in water. Mercury is highly toxic so that it causes negative impacts on the environment and public health. Bioremediation is one of solution to reduce mercury waste pollution. Mercury bioremediation using microorganisms and adsorbents requires appropriate process steps to be effective in eliminating mercury. This study aims to determine the effect of the bioremediation steps on the effectiveness of mercury (Hg) elimination in liquid media and to determine the most effective bioremediation steps for mercury (Hg) elimination in liquid media. This study used an experimental method with a non-factorial Completely Randomized Design consisting of treatments, namely control (K), treatment 1 (T1), treatment 2 (T2), treatment 3 (T3), treatment 4 (T4), with 5 (five) times repetition. Analysis the results of the bioremediation stage used AAS (Atomic Absorption Spectrophotometry). Data were analyzed using One-way Anova test, LSD test and effectiveness test. The results showed that the bioremediation stage had a significant effect on the effectiveness of mercury (Hg) elimination in liquid media, this was proven by the results of statistical tests carried out using the One-way Anova test and further tests where the different reduction data obtained from each treatment. The initial level mercury 10 ppm, after being given treatment decreased T1 to 1.25 ppm, T2 to 1.33 ppm, T3 to 1.06 ppm, and T4 to 1.24 ppm. The most effective bioremediation step for the elimination of mercury (Hg) in liquid media is the T3 stage starting from Mercury Waste→Microalgae→Bacteria→Red Clay→Activated Charcoal, with a mercury reduction effectiveness value of 89.4%.

Abstract

Sengon (Falcataria moluccana) is a legume that generally has physical dormancy. Physical dormancy causes slow seed germination if the dormancy is not broken properly. Many studies have been reported regarding dormancy breaking treatment with hot water on sengon seeds, but rarely use mechanical scarification treatment. The purpose of this study was to examine the effect of mechanical scarification on sengon seed germination. The experimental design used was a one-factor Completely Randomized Design (CRD). The factors used were the mechanical scarification technique (3 treatments), namely P1:  control, P2:  pricking the seed with a needle, and P3:  cutting the tip of the seed. The germination parameters used were the percentage of germination (PK), peak value (PV), average daily germination (MDG), and germination value (NK). The results showed that the PK values for each treatment were P1 = 55%, P2 = 75%, and P3 = 72%. The PV values were P1=15.18, P2=17.75, and P3=17.53. The MDG values were P1=0.92, P2=1.25, and P3=1.20. The NK values were P1=13.90, P2=22.28, and P3=22.13. P2 treatment (needle prick) gave the highest response on all parameters of sengon germination. Based on the results of the Analysis of Variance (Anova), it was found that the treatment had a significant effect on the parameters PK, MDG, and NK. While the PV parameters showed no significant difference.

Abstract

The Indonesian government's food estate program aims to achieve food security through the use and improvement of agricultural land, one of which is in peatland areas. The implementation of the food estate program in Indonesia needs to comprehensively consider environmental, economic and social aspects, so that it will not only provide benefits to the wider community, but also pay attention to the ecological functions of the peatland ecosystem. In this paper, a study is carried out on several aspects such as the availability and potential of peatlands for agriculture, the right commodities for agricultural activities on peatlands, examples of the economic benefits of peatland agriculture, and the involvement of local communities as indicators of sustainability of the food estate program. The discussion is carried out using the perspective of environmental science and FEW Nexus. The results of this study explain that the food estate program on peatlands needs to pay attention to several challenges in the environmental, social, and economic sectors. Furthermore, food estate on peatlands is also considered necessary to be implemented within the framework of the FEW Nexus in order to become a sustainable program.

Abstract

Gold mining without a permit is one of the activities that results in a decrease in environmental quality, because gold mining activities use mercury to separate gold ore from rocks until the refining process. The purpose of this study is to identify and analyze the implementation of law enforcement against gold mining without a permit and controlling the environmental impact of gold mining without a permit in Sintang District, Sintang Regency. The type of research is sociological juridical. Data collection by interview and observation was then analyzed by qualitative methods. Unlicensed gold mining is caused by economic factors, education and the community feels they have the right to manage natural resources. Gold mining law enforcement without a permit applies criminal law with the imposition of fines and is still not optimal due to several constraints on the location of miners moving around, the absence of regional regulations related to PETI and community resistance. The government's efforts to control environmental impacts on water pollution from PETI activities are monitoring water quality conditions on a regular basis.

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).
