Abstract

Riau Province, which has a peatland area of ​​5.09 million hectares or 56.42% of the area of ​​peatlands on the island of Sumatra, is one of the provinces in Indonesia which has the greatest potential for forest fires to devastate hundreds of hectares of forest and gardens and increase home gas emissions glass in the atmosphere. Forest fires that occur are closely related to Consecutive Dry Days (CDD) or consecutive days without rain (HTH) which result in low humidity, thereby affecting the potential for hotspots to emerge, especially around peatlands. CDD, which is the result of the accumulation of the amount of HTH in one period between rainy day events, is calculated using CMORPH precipitation data (CPC MORPHing technique). Hotspot data is obtained from NOAA and Hotspot event data with a confidence level of more than 70% in the eastern region of Riau province where there is a peatland. The probability of a Hotspot occurring is calculated based on the CDD for each grid that will produce a CDD value with a significant probability for the occurrence of a Hotspot on the grid each month. The level of density of Hotspots in each season period with a high category is in the JJA and MAM periods. An early warning system for the emergence of a Hotspot based on the level of Hotspot and CDD density is carried out the day before the opportunity arises with a value less than or equal to 0.5. With an average CDD value for early warning in MAM is 13 days and in JJA is eight days. This research is expected to be able to be applied in early warning of forest and land fires in Riau.

Abstract

Jakarta and its surroundings areas that have high surface temperatures due to high total CO2 emissions. High CO2 emissions will cause surface temperatures to increase due to the phenomenon of greenhouse gases. An increase in temperature will also have an impact on increasing heat strs which will be dangerous if no steps are taken for prevention. The El Niño – Southern Oscillation (ENSO) factor is also considered influential in terms of the value of heat stress. Calculating heat stress in Jakarta and surrounding areas can be done by the Wet-Bulb Globe Temperature Index (WBGT) method. Data was obtained from six station points in Jakarta and surrounding areas in 1993 – 2018 consisting of daily air temperature and humidity and using Oceanic Nino Index (ONI) data to determine the ENSO period. The results show that the highest WBGT were identified in four regions, Tanjung priok, Kemayoran, Cengkareng and South Tangerang with ISBB values ​​of 30 – 32.5 (the heat stress increases to dangerous levels), while for the other two, Curug and Dramaga Bogor have WBGT values at 28.5 – 30 (heat stress increases). The most dangerous WBGT category was in Tanjung priok in April during El – Niño with 71% (58) days were in the dangerous category, while the WBGT category had the least heat stress at Dramaga in August when it was neutral with 17.7% (66) days were in the no heat stress category. When El-Niño ISBB was higher than when it is neutral and La-Niña and has higher minimum and maximum extreme values than when it is neutral and La – Niña.
