Abstract

The Durslin Watershed is one of the watersheds located on Singkep Island, Lingga Regency, Riau Islands Province with an area of 99.80 km2. In accordance with Permen PUPR (2018), the Lingga Regency River Area is in the medium-critical zone. However, the local government plans to increase the irrigation areas as the highest contributor to the economy. The expansion of the irrigation area must be supported by an adequate water supply. So it is necessary to conduct research related to the irrigation water demand in the Durslin watershed. The method for determining evapotranspiration is using Penman-Monteith with calculations based on the KP-01. The analysis is then projected for the next twenty years to 2040. Result the research show that the demand for irrigation water is always increasing every year. In 2021 irrigation water demand is 0.1022 m3/sec, while irrigation water demand in 2040 is 0.2922 m3/sec.Keywords: irrigation, watershed, water demand

Abstract

Upper Siak watershed is increase discharge caused by the land use change. Therefore, this study is aimed to calibrate the parameters of the flood discharge in the upper siak watershed. Various hydrological modeling to calculate the flood discharge have been developed, one of them that is used in this study is the HEC-HMS (Hydrologic Engineering Center-Hydrologic Modelling System). Calibration parameters intended that the flood discharge output HEC-HMS approaching the flood discharge observation. Calibration data input is in the form of daily rainfall data, hourly discharge, and land use maps of 2012. Based on the calibration results showed that the flood discharge has a duration of 3 hours have simulated peak flow value of 70,99 m³/s while the observed peak flow amounted to 71,06 m³/s with a percent difference of 0,1% and the flood discharge duration of 6 hours have simulated peak flow value of 70,60 m³/s while the observed peak flow amounted to 71,06 m³/s with a percent difference of 0,6%.Keywords: land use change, calibration, flood discharge, HEC-HMS

Abstract

Lubuh River which is located in the stems of Rokan Hulu Riau Province is one of the rivers that often have overflow water. Hydrology analysis is necessary to help the process of flood mitigation in Rokan Hulu. The advancement of technology in remote sensing has provide an alternative solution of data availability in hydrological modeling by using data obtained from the satellite. This research took the case study of AWLR station of Pasir Pengaraian in Rokan watershed with the length of the data in two conditions at the stage of no calibration. One condition for fourteen days (February 13, 2012 00:00 to February 26, 2012 period) and two conditions for six days (01 may 2012 00:00 to 06 may 2012 23:00 period). Based on the results at the beginning and the calibration process simulation, wave shape error after calibration is smaller than the initial simulation. While the value of the volume error and peak discharge error in the initial simulation is smaller than the calibrated value. The value of each parameter of the wave shape error, error and peak discharge volume error are 33.6176%, 8.6025%, and 5.8720% respectively at beginning of simulation in condition two and 0.0169%, 15.4120% and 28.7533% in the calibration process.  Keywords : hydrological modeling, flood analysis, satellite data, IFAS

Abstract

Drought is one of the phenomena that often happen every year in some regions of Indonesia. Therefore, it is necessary to do drought index analysis to know the level of drought so that it can be used for early against peat fire disaster. Analyzing level of drought in peat land in this research used SPI (Standardized Precipitation Index) method based on GIS (Geographic Information System). The data used were monthly rainfall data taken from TRMM (Tropical Rainfall Measuring Mission) satellite in the area of Tebing Tinggi Island from 2009 -2016. The calculation of SPI index was conducted on monthly and half monthly period in each designed grid. The results show that in monthly period, the severe drought index values occurred on grid 21, February of 2014 at -4.007 (Very Dry), whereas the period of half monthly values of severe drought index occurred on grid 4, the month of February 2 of 2014 was -4.896 ( Very Dry). The results indicated that the calculation of the half monthly period is better than the monthly period, because the result of the half monthly period is more detailed. Keywords: Drought Index, Standardized Precipitation Index, TRMM, Drought Distribution Mapping.

Abstract

Peat water is water that available on surface or ground water, it has been affected by the characteristic of the peat. These conditions make well water in that area can not be consumed. Water treatment process needs to be done to improve the water quality. One of them with a simple concept and experiencing is rapid sand filter. The purpose of this study was to determine the effectiveness retrospective on the addition of saturated filter backwashing installation. Reactor rapid sand filters without backwashing and rapid sand filter by backwashing made of PVC pipe diameter 6 " and high 50 cm. The results showed rapid sand filters without backwashing produce the best effectiveness to raise the pH value of 7,96 % and lowers the organic content of 29,31 %. While the rapid sand filter by backwashing produce the best effectiveness in raising the pH value of 5,81 % and lowers the organic content of 30,43 %. In general, the processed peat water from rapid sand filter is capable of improving the water quality of the peat.Keywords : peat water, rapid sand filter, backwashing, water quality

Abstract

Bengkalis Regency has rice fields with an area of 5,014 ha. The extent of this rice field is a potential that can support the availability of food to meet local and regional needs. One of the irrigation areas in Bengkalis Regency is the Daerah Irigasi Rawa Sepotong in Langkat Village. This irrigation has an area of 326 ha and is a rainfed irrigation area that only utilizes rainfall to meet irrigation water needs. Although in the rainy season the irrigation water needs are met, in the dry season the rainfall is not able to meet the irrigation water needs. One alternative source of water for this irrigation area can be taken from the Siak Kecil River. However, the water level of the Siak Kecil River is lower than the elevation of the rice fields, so pumping is needed to drain the water. This research was conducted by using various secondary data and analyzing the feasibility of the pumping development. Based on the data analysis, it was found that the availability of reliable discharge (Q80) of the Siak Kecil River using the F.J Mock method was 31.5 m3/s with the highest irrigation water requirement in August period I of 0.68 m3/s. With a very high level of water availability compared to the irrigation water needs of the area, technically the construction of irrigation pumping is feasible.  Keywords: F.J Mock method, feasibility, irrigation, irrigation water needs, pumping, water availability.

Abstract

The existence of laundry has a positive impact on the community but actually has a negative impact on the environment. Chemical compounds contained in laundry water such as surfactants, can trigger eutrophication in water bodies. If this is allowed continuously will cause water pollution problems. Floating Treatment Wetland (FTW) comes as an option that can be used to decompose water pollutants by utilizing macrophyte plants. This research aims to describe the application of FTW as one of the potential methods for laundry wastewater treatment because it is minimally costly, environmentally friendly, and sustainable.Keywords : Laundry wastewater, FTW, water pollution.

Abstract

The rapid growth of  the Indonesian  population  will  produce  more and more wastewater. Throwing domestic wastewater directly without treatment had caused the water pollution. One of simple, easy, low cost in maintenance and operation technology to decrease the pollutant in wastewater is constructed wetland. This research is aimed to know the efficiency and the best of detention time Subsurface Flow Wetland 2 levels with peat soil media and plant of Alisma plantago in treatment of domestic wastewater. The quality parameters of water that  was tested  are  pH, COD, and TSS.  Statistic calculation that was used in this research is Anova (Analysis of variance) of one way. The best efficiency for pH 31.7%, COD 82.1%  and TSS 90.3% in variance 4 with time of detention 4 days in reactor 1 and 1 day  in reactor 2. The  results showed  that the constructed wetland  2 levels  using  peat  soil media  and  plant of Alisma plantago  can  improve the quality of wastewater.
