Abstract

Peat restoration on peatlands is needed to restrain the rate of further damage from peatland ecosystems, one of which is a peat rewetting activity that is a way to re-wet the peatland using canal blocking to keepthe groundwater level at max 0.4 meters below the surface. Groundwater flow analysis was carried out in Lukun Village, Tebing Tinggi Timur District, Meranti Islands using Paper disc velocimeter (PDV)and groundwater level measurements using measuring pipes on 5 deep wells on the upstream transect and 5 deep wells on the downstream transect with a distance of 50 m and 100 m canal blocking. Theresults obtained from the Velocimeter Paper disc are the velocity and direction of flow in the upstream and downstream transects of the canal blocking, where groundwater flow rates are higher in thedownstream and lower in the upstream due to canal blocking. The benefit of having a canal block is that the groundwater flow rate in the upstream transect can be held up to the canal because the elevation ofthe channel's water level has been successfully raised.Keywords : peatland, canal blocking, paper disc velocimeter, groundwater flow.

Abstract

Drought is the decrease in the amount of rainfall from its normal condition and depends on how long it lasts. This study aims to determine the characteristics of drought that occurs in the longest duration of drought and the largest number of drought in the location of rain stations spread in Palambayan basin. Then can be used as early warning of drought disaster and help for the interest of planning design at Palambayan watershed. The method used to analyze drought is Run Theory method. The location of the study was in the Palambayan Basin of West Sumatra Province. The data used are monthly rainfall for 10 years (2007-2016) from 2 rain stations located in the Palambayan River Basin and 1 Rain Station located outside the Palambayan River Basin. The results showed that the largest cumulative drought occurred in 2008 of 283.49 mm at Muaro Tantang rain station. For the longest duration of drought is 9 months in 2009. Based on the result of drought distribution map using Geographic Informaton System (GIS), the worst drought station is Gumarang Station.Keywords: Drought Analysis, Run Theory, Drought Index

Abstract

A drought occurs when there is a lack of precipitation over an extended period of time, usually a season or more, resulting in a water shortage. BNPB, National Disaster Mitigation Regency has issued a drought disaster risk index map in Riau province which has a moderate and high level of drought risk. Siak regency is one that is experiencing the risk of drought in riau province. Therefore, drought index analysis using rainfall data from TRMM satellite (Tropical Rainfall Measuring Mission) was analyzed using Standardized Precipitation Index (SPI) method. Drought deployment and hotspot calculations in maps in GIS (Geographic Information System). A half month period on grid 5 with a value of (-4.589) and a month on grid 4 with value (-3,863) in February 2014 is the most severe dry category SPI classification. The association of fires affected by the meteorological drought index affected the a half month period due to the presence of more fires. However, not only the meteorological drought index affects fires, but can be caused by soil types, land cover and over land conversion.Keywords: drought, drought index, SPI, TRMM, GIS
