Abstract

Abstrak.  Luas Sub DAS Krueng Jreue 23.218,06 Ha dan Sub DAS Krueng Khee 9.599,66 Ha. Berdasarkan hasil kajian bahwa luas vegetasi tutupan lahan semakin berkurang setiap tahunnya dimana ditandai dengan tingginya nilai fluktuasi debit sehingga mengakibatkan banjir pada musim hujan dan kekeringan pada musim kemarau. Tujuan penelitian adalah untuk mengetahui nilai ambang batas kekeringan hidrologi di Sub DAS Krueng Jreue dan Sub DAS Krueng Khee dan indeks kekeringan hidrologi di Sub DAS Krueng Jreue dan Sub DAS Krueng Khee. Penelitian ini menggunakan metode ranking Weibull dimana ditentukan nilai ambang batas Q50 dan Q80, dihitung defisit dan durasi dan kemudian ditentukan nilai indeks kekeringan hidrologi. Nilai ambang batas Sub DAS Krueng Jreue adalah 0,067 m3/s dan Sub DAS Krueng Khee 0,181 m3/s. Defisit Sub DAS Krueng Jreue tahun 2014 adalah tertinggi dengan angka 0,401 m3/s dengan durasi kering tujuh bulan dan Sub DAS Krueng Khee tahun 2012 adalah tertinggi dengan angka -0,715 m3/s dengan durasi kering enam bulan. Indeks kekeringan hidrologi di Sub DAS Krueng Jreue tahun 2015 adalah tertinggi dengan nilai 0,0629 m3/s dan indeks kekeringan hidrologi di sub DAS Krueng Khee tahun 2011 adalah tertinggi dengan nilai 0,3282 m3/s.An Analysis of The Krueng Aceh’s Hydrological Drought Index  (A Case Study of The Sub Watershed Krueng Jreue and Krueng Khee)Abstract.  The area of the Krueng Jreue Sub-watershed is 23,218.06 Ha and the Krueng Khee Sub-watershed is 9,599.66 Ha. Based on the results of the study that the area of land cover vegetation decreases every year which is indicated by the high value of discharge fluctuations, resulting in flooding in the rainy season and drought in the dry season. The purpose of this study was to determine the threshold value for hydrological drought in the Krueng Jreue Sub-watershed and Krueng Khee Sub-watersheds and the hydrological drought index in the Krueng Jreue Sub-watershed and Krueng Khee Sub-watersheds. This study uses the Weibull ranking method where the threshold values for Q50 and Q80 are determined, the deficit and duration are calculated and then the hydrological drought index value is determined. The threshold value for the Krueng Jreue Sub-watershed is 0.067 m3/s and the Krueng Khee Sub-watershed is 0.181 m3/s. The Krueng Jreue Sub-watershed deficit in 2014 was the highest at 0.401 m3/s with a dry duration of seven months and the Krueng Khee Sub-watershed in 2012 was the highest at -0.715 m3/s with a dry duration of six months. The hydrological drought index in the Krueng Jreue Sub-watershed in 2015 was the highest with a value of 0.0629 m3/s and the hydrological drought index in the Krueng Khee Sub-watershed in 2011 was the highest with a value of 0.3282 m3/s.

Abstract

The existence of forest park areas plays an essential role as carbon sequestration can reduce the concentration of greenhouse gases in the atmosphere. Analysis of carbon potential is essential in determining the amount of available carbon potential. This study aims to analyze the carbon potential in the forest park area Pocut Meurah Intan Forest Park. The study used a descriptive method with the sampling technique of the path system. Data analysis and calculation of carbon potential using allometric equations to calculate the total biomass. Spatial analysis using Arc.GIS 10.4 software and the carbon content analysis was carried out using the ashing method. The results showed that the potential carbon stock of Pocut Meurah Intan Forest Park was 640,282 tons. The carbon potential is the carbon stored above the ground in the form of carbon from above-ground biomass (trees, poles, saplings, undergrowth) and organic matter (necromass and litter). The highest carbon potential was found in the secondary dryland forest land cover with a total of 555,204 tons or 167.6 tons ha1 , followed by shrubs of 78,949 tons or 33.3 tons ha -1 , and the lowest potential carbon stock was found in the open field of 303 tons or 2.8 tons ha-1 . The increase in land cover in secondary dryland forests causes increased carbon storage. The low potential for carbon stocks is due to land clearing and a small number of stands, resulting in a decrease in potential carbon stocks.

Abstract

The land requirement for Putri Betung Sub District in Gunung Leuser National Park (GLNP) area kept increasing along with the population growth. The population density in the Putri Betung Sub-district was driven by the need for cultivation and residential area along the GLNP conservation boundary. This study aims to analyze the space adequacy for Putri Betung Sub-District in the GLNP area based on the population pressure prediction for 20 years. The research method was conducted by field survey using remote sensing, interviewed the residents, and analyzed the population pressure index using the Soemarwoto formula. ThePopulation Pressure Index (PPI)forthe cultivation area was determined from 13 villages in Putri Betung Subdistrict and shows that 12 villages had a PPI 1 value (population pressure was over the land carrying capacity limits). Only one village had PPI 1 (population pressure less than the land carrying capacity. Based on data surveys obtained, the cultivation area set in the Putri Betung area was no longer sufficient for population, resultingfrom the expansion in the GLNP area of 4,776.97 ha. Meanwhile, predictive analysis on space adequacy for people living decently in Putri Betung Sub District for 20 upcoming years is 6117.15 ha. In conclusion, 12 out of 13 villages in the Putri Betung SubDistrict havePPI 1 value, which is inversely proportional to the land carrying capacity. The PPI values could result in other pressures on the ecology and biodiversity conservation in National Park. It is suggested that the government need to surpassthe pressure by making new policy on peoples resettlement, expanding the cultivation area, or shifting people's livelihoods.
