Abstract

One of the factors causing fires in peatlands is due to the condition of dry peat. This condition can be caused by uncontrolled human activities such as digging canals that can lead a significant decreasing change of groundwater level in peatlands and cause peat to become dry. The Government of Indonesia, through BRG, is attempting to Rewetting the peatland by canal blocking. How effective the impact of canal blocking is analyzed in this study. To analyze the fluctuation of groundwater level as impact of canal blocking changes before and after canal blocking using water level loggers. Groundwater level monitoring was carried out on 3 transects, namely, 1 transect in the downstream side which is 100 m from the canalblock and 2 transects in the upstream side which is 114 m and 491 m from the canal block. The results showed that the canalblock had a good impact for keeping groundwater elevation and keeping peatland on always wet condition until 419 m with an increase of 0,005 m to the upstream area from canalblock and around 240 m with an increase of 0,005 m perpendicular to the canal.Key words: peatland, canal blocking, Rewetting

Abstract

This paper presents the application of satellite remote sensing techniques to detect and identify peatland cover types in Riau Province, Indonesia. Mapping the spatial distribution of organic soils is important for decision making in land management and mitigation of peatland forest fires. Organic soil types have a strong effect on carbon storage, water availability and quality, biodiversity and many other ecosystem services. This study uses GIS software and Landsat-8 satellite data to identify the type of peat land cover in Tebing Tinggi island. This area were picked up as pilot project areas for this research, because these areas historically had many fire spots on last few years. The results show how this approach can be used to land cover classification and for predicting mineral and organic soils in locations within the map unit quickly and cost-effectively. The identification of Peatland was done using composites of band ratios and single band variables. The best composite band ratio that can be used is a 7-5-3 band combination. This combination consists of band 7 (Shortwave Infrared 2), band 5 (Near Infrared) and band 3 (Green). This combination is selected because it can classify land cover of peatland into 5 classes, there are primary peat swamp forest, disturbed / regrowth peat swamp forest, agriculture mosaic, burn scars or urban areas, missing data or water. The result of data processing of Landsat 8 Satellite image shows that 95% of Tebing Tinggi island area is composed of peatland. Based on the results of data processing Citra Landsat 8 can be seen some areas of Tebing Tinggi islands indicate red color means the area of burn scars or burn earth. The result of fire point processing shows the largest number of hotspots existed throughout the year 2014 with the number of fire points as much as 1351 points. In the year 2013 with the number of hotspots as much as 110 points and the smallest occurred throughout the year 2015 with the number of points of fire as much as 79 points. The result map peatlands will be useful for land management and carbon storage decisions in the soil in an effort to prevent land and forest fires. Keywords: GIS, remote sensing, peat, land cover, hotspot.

Abstract

In Siak regency, there are 10,000 hectares OF TORA land (Land object of agrarian reform) which is a peat area and 92% of them are deep peat. An area of 2,000 Ha of the total number of TORA land is at HGU 07. The Local Government of Siak Regency will manage the peatland productively in economic terms but does not damage the peat ecosystem. Based on PP RI number 57 year 2016 on protection and management of peat Ecosystem, the peat ecosystem with cultivation function is declared to be damaged when water level in peat land more than 0.4 meters below the peat surface at the linking point. The purpose of this research is to predict the fluctuation of groundwater in consideration to support the efforts to optimize the development of environmental commodities peatland in Siak Regency. The effort to maintain water level above 0.4 m is so that PP RI No 11 Tahun 2009, peat is kept in wet conditions for carbon emissions and the threat of land and forest fires due to drying of land can be reduced. Ground water advance fluctuations are predicted using linear regression methods. The results showed that the result of the calculation obtained the value of efficiency Of Determination In the highest dwrain analysis of 3 months with a data length of 0.5777. The prediction of ground water advance fluctuations in May – December means that water depth is not in accordance with government regulations that set a water level height of less than 0.4 m below ground level. Alternative commodity can live with government regulation if planted in surplus month, namely February to April.Keywords : hydrology, water balance, peat land, regression analysis, water level

Abstract

Bengkalis Island is a peat island which is prone to beach abrasion. Abrasion happens at the rate of 32,5 m/year,especially on the west of Bengkalis Island. The relatively lightweight characteristic of peat materials makes it moresusceptible to beach abrasion and sedimentation. Since peatland beaches are very rare in the world, study aboutpeatland beaches abrasion was also rarely done. To understand this phenomenon, this study has made a physicalmodel in the laboratorium. Experiment using this physical model was done in Hydrotechnical Laboratorium atDepartment of Civil Engineering, Universitas Riau, through Multi Teaching Flame method, while the sample materialof peat soil from Bengkalis Island Beach was subjected into preliminary property test. Experiment was done using 3scenarios of wave height generated by wave generator, and 3 variation of beach slope, which was 1:2.5, 1:5 and1:7.5. Data taken on this study were elevation of peak and valley of the wave (H), wave period (T) and sedimentheight (d) which was measured every 30 minutes for 300 minutes. Morphological changes of beach as a result ofbeach abrasion and sedimentation are further evaluated in terms of wave height and beach slope. Through this study,it can be concluded that wave length and rate affected by depth of the sea. The smaller the slope of the beach, themore stable the beach, which make it more susceptible from erosion.Keyword: Bengkalis Island, Morphological Changes, Physical Model, Wave and Slope

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

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

Cipogas lake has a non-uniform topography, that non-uniform topography caused flow patterns. Which results in a non-uniform of velocity and sediment distribution and then influences the changing trend of the reservoir bed configuration. Hydraulic simulation has used a RMA-2 model to determine flow patterns and velocity distribution. Topographic data, flood discharge, and surface water elevation are used as basic data for RMA-2 processing. Sediment transport simulation has used a SED2D module to generate sediment movements. The grain size and sediment concentration are used as a basis for SED2D processing. The simulation results showed that the flow pattern affects the velocity distribution and sediment distribution at certain times in the lake so that there is a change in the lake bed configuration. The bed configuration of the cipogas lake based on simulation results is classified in the Transition and Dunes. Keyword: flow patterns, sediment distribution, bed configurations

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
