Abstract

During 2018 there were quite severe fires in South Sumatra, one of which was Musi Banyuasin Regency. Approximately 38,000 hectares of land were burned due to the condition of the vast and dry peatlands making it difficult to extinguish during a fire. The peat layer will also be prone to fire if the groundwater level is deeper than 40 cm. Efforts to maintain a height of less than 40 cm are monitored by the groundwater level by direct measurement in the field. High monitoring by direct measurement is carried out using a Sensory data transmission Service Assiated by Midori Engineering (SESAME) tool that can record rainfall, temperature, and surface water data. The purpose of this study is to make a prediction model of water level on peatlands using a regression method and predict water level on peatlands within a certain period. The results showed that the regression analysis with a period of 1 month, 3 months, and 6 months to get the results of the prediction of groundwater level with a strong correlation coefficient value of 0.756; 0.773; and 0.742. Whereas in the regression analysis for 9 months, the prediction results of the groundwater level with a moderate correlation coefficient are 0.524.Key words: groundwater level, rainfall, regression analysis, peat

Abstract

Air Hitam River is one of the river in Pekanbaru which have the function as the main drainage of the Pekanbaru city. In the past, land surrounding the Air Hitam River Basin is dominated by vegetation that can infiltrate rain water, but as the development of the city, the vegetation areas has changed to housing, offices, warehouses and trade. The change of land use will influence hydrology condition and make river flow higher. If the river is not able to accommodate the rain water, it will cause flooding which cause harm to the surrounding community. For this conditions, it is required data and information about the Air Hitam flooding in the watershed. This study uses the integration of Geographic Information Systems (GIS) and hydraulics models in Hec-GeoRAS. This research used existing land use data in 2010, land use plan in 2026, and land use in extreme condition to estimate. The result showed that in period from 2010 to 2026, the vegetation areas has decreased amounted to 56.778 % to 21.641 %. This causes the value of the composite runoff coefficient land greater so the river can’t accommodate the flow occurs. Discharge that exceeds the capacity of the river caused flooding of 4.5 ha by 2010, 322.338 ha by 2026 and 372.645 ha by extreme conditions.  Keywords: land use, flood inundation, Hec-GeoRAS

Abstract

Peatland fires in Indonesia occur almost every year with an ever-increasing area. Factors affecting peat drought and fire are the high and low ground water level of the peat, for this reason it is necessary to review how high the peat water level can cause a fire so that it can be used as an early warning before peatland fires occur. This study created a hydrological model using regression analysis to predict groundwater levels in peatlands which were then verified using correlation coefficients. The data used were obtained from the SESAME tool namely rainfall data and water surface data recorded in time series per 10 minutes. The hydrological model is carried out with several variations of data usage periods to get the best value. The results showed the use of data for the period July 2017 - December 2017 got the best correlation coefficient value of 0.86, while the use of data for the period February 2018 - July 2018 obtained the lowest correlation coefficient value of 0.15.Key words: Fires, hydrological models, regression analysis, peatland

Abstract

Tanjung Leban Village is a village whose majority consists of deep peatlands, reaching depths to dozens of meters. The condition of the ground water level far from the surface of the peat soil causes the peatlands to be prone to fire. Government Regulation No.57 of 2016 states that the height of the ground water level on peatlands must be maintained so as not to fall less than 40 cm below the surface of the peat. The peat restoration agency established a canal blocking program to raise and maintain the ground water table 40 cm from the ground. So how is the influence of canal blocking on ground water level and mapping the level of fire risk. Groundwater level data obtained in the field from the height of measurements using a float on a monitoring well. The analysis shows that water flow tends to flow from the land into the canal, because the water level in the land is higher than the water level in the canal. The installation of the canal raises the groundwater level 60.5 cm and affects the water level to a distance of 476 m from the canal, after that the ground water level can only be increased by rainfall and water distribution from the concession area. The highest fire risk level was in February with a percentage of 100%, while the lowest risk level was in January with a safe percentage of 1.74%, standby 1.67% and danger or hazard-prone to 96.58%.

Abstract

Significant shift in the land use within Siak watershed (DAS Siak) affects to groundwater reserves. This also affected to fluctuation of the river flows. Therefore to develop a comprehensive watershed management strategies, it is required a hydrological model which is in capable to represent the hydrological cycle of the watershed. Hydrological model may use SWAT application software package. The SWAT simulations performed various scenarios for land use changes in the period of 2002, 2007, and 2012. Based on this research study, the optimal determination coefficient (R2) of SWAT output models were = 0.59, with Nash Suflicfe Efficiency (NSE) was 0.58. The determination coefficient for validation models was 0.55 and NSE was 0.48. These results have satisfied the reserach objectives as the findings coefficient were > R2 min 0.4, and >NSE 0.35. The level of ground water reserves was calculated by comparing the ratio of Qmaximum and Qminimum during the period of 2002 to 2012. It was revealed that the ratio of ground water reserves were as the following order 10,725 (2002), 6,834 (2007) and 12,951 (2012) respectively. Should the ratio value Qmaxsimum / Qminimum was bigger, the more critical ground water reserved will be. Hence, the fundamental changes in land use is Siak watershed affected to suppress the ground wateer reserve to the critical level.Keywords: Land use change, SWAT model, ground water reserve.

Abstract

Banda Aceh is one of the cities in Sumatra that is affected by the earthquake and tsunami Andaman on 26 December 2004. Banda Aceh has a sloping and relatively flat topography, with an average height of 0.8 meters above sea level, making this city became one of the cities with The worst effects of tsunami 2004, and still have the risk of earthquakes and tsunamis in the future. It is necessary for the system in the form of vertical evacuation like escape building, so that residents can take refuge from the tsunami. However, the number and location of the escape building existing only found in the Meuraxa village, so it can not reach all areas of tsunami inundation. This research use network analyst tool to the configuration of the escape building existing to analize the service area of each escape building. From this analysis it can be known that there are still many people who are not able to reach the nearest escape building or toward a secure area before the tsunami waves arrive. The scenarios analysist simulate varying evacuation time conditions, and there are two overload escape building. The simulation result shows that the percentage of residents who are not able to reach an escape building is very small, ranging between 23.73% -10.35%, so it is considered not effective, while the analysis of the escape building existing capacity shows two escape building had excess capacity, ranging between 55.48% - 55,78%.Keywords: Banda Aceh City; service area; escape building

Abstract

Stages of disaster mitigation study consists of the level of hazard, vulnerability and capacity. Pekanbaru, the capital of Riau province has the potential to flood inundation. An assessment of the vulnerability of flood inundation using GIS technology be done in twelve districts in the city of Pekanbaru. This study was conducted as a early warning to the public and to the relevant parties. This study uses two parameters causes of flood inundation, such as the parameter of flooding inundation (landform, slope either side of the river, damming the river branching, meandering rivers, and waterworks) and parameters of flood inundation potential water supply (rainfall, river basin shape, drainage density, slope watersheds, and land use). By analyzing satellite imagery data (DEM and Landsat 8 OLI), rainfall data, and administrative map of Pekanbaru City area with the help of GIS technology, the results of the analysis of these two parameters indicate that the city of Pekanbaru has a weighted average score is 2.70, so that the city of Pekanbaru has a severe impact categories rather prone to flooding inundation. The weighted scores of the two parameters in the city of Pekanbaru has shown that the land (weighted score of 1.33), the availability of water building (weighted score of 2.25), and the use of land (weighted score of 1.20) has a considerable influence on the cause of the flood puddles in the city of PekanbaruKeywords: inundation flood, GIS, parameters of flood, vulnerability
