Food insecurity happen because agriculture is not handled well. Parameter optimalization is planned based on the decision-making system method of Analytical Hierarchy Process (AHP) which are : Technical, Economic, Environmental, and Social/Cultural. The results of the AHP analysis with the help of Expert Choice program 2000 found that the most influential criteria in optimizing the use of irrigation water is technical criteria. The percentage of some criteria are technical criteria 39.9%, economic criteria 36.0%, environmental criteria 15.9%, and the criteria of social/cultural 8.1%. In addition, sub-criteria that most affect the optimal use of irrigation water are the cost of development and rehabilitation work of irrigation channel, the performance of the channel, and cooperative farmer groups P3A, where the three sub-criteria above must be maintained well. While the sub-criteria which need to be improved are the presence of a water keeper, the availability of funds to finance the annual operation and maintenance of irrigation, as well as the condition and function of irrigation channel.Item KAJIAN PEMENUHAN KEBUTUHAN AIR BAKU DI KOTA PASIR PENGARAIAN KABUPATEN ROKAN HULU(2013-07-25) Saputra, Wirya; Fauzi Manyuk; SiswantoThe needs of clean water in Pasir Pengaraian City increasing in line with population growth and urban growth. Water supply systems that are currently held by BPAB still have the problem with the lack of service coverage. Therefore, the existence of Lubuk Batang River is expected to be a solution to overcome these problems. This study uses IHACRES in modelling flow discharge, which in calibration stage generated the R2 value of 0,437 with a bias 53,131 mm/year. Analysis for the availability of water is done by analyzing the mainstay of river discharge (Q90%) based on the average annual discharge that produced the flagship in 2005. Mainstay discharge occurred in January 2005 amounted to 260,8 m3/sec and smallest discharge in June 2005 was 30,5 m3/sec. Analysis of water needs is projected to the population growth in the next 10 years, produced the total water demand for the Pasir Pengaraian City’s (Rambah District) service area at the beginning of the projection year (2012) that is equal to 0,0491 m3/second (49,082 liters/sec), while the total requirement water at the end of the projection year (2022) amounted to 0,066 m3/second (65,962 liters/sec). The analysis showed that the available flow at Batang Lubuk River very inadequate even exceed the total water demand in the area of service coverage.Item PEMODELAN HIDROLOGI HUJAN-ALIRAN DENGAN MENGGUNAKAN DATA SATELIT HASIL PENGINDERAAN JAUH (Studi Kasus DAS Tapung Kiri)(2013-06-29) Hamiduddin; Sutikno Sigit; Fauzi ManyukHydrological modeling is a simplification or approximation from an actual reality of hydrological phenomena. Data’s availability for modeling is often become a problem because of incompleteness and imprecision data. Advancement of remote sensing technology makes it possible to overcome these problems by using data derived from satellites. To use satellite’s data for hydrological modeling needed a special software, one of it is the Integrated Flood Analysis System (IFAS). IFAS was be used to model the rainfall-runoff in Riau Province, Tapung Kiri watershed. This model was simulated and calibrated with period from 1 January until 31 December 2006 and then was validated with period 1 January until 31 December 2005. Modeling become optimal after the calibration process with the correlation (R) value of 0,776, volume error (VE) of 0,574%, and the coefficient of efficiency (CE) of 0,75. This showed that the model has a high degree of association with the measured data (0,7Item PENGGUNAAN DATA HUJAN SATELIT UNTUK PEMODELAN HIDROLOGI DAS INDRAGIRI(2013-07-17) Hasan, Hasniati; Sutikno Sigit; Fauzi ManyukThe use of modeling techniques in hydrology research is now highly developed. It can be seen from the increasing number of hydrologic modeling that appears along with the development of knowledge and the advancement of computer technology. IFAS is a remote sensing program that was developed by a research institution of the Japanese public works called the International Centre for Water Hazard and Risk Management (ICHARM). the IFAS system has several parameters are initially set to default parameter values based on the data downloads from the satellite. This parameter is then calibrated by using a reference from the local hydrological data observed (measured data). If we do not have measured data then must use the default parameter values. Rain hydrological modeling process is carried out in the watershed flow Lubuk Ambacang with data length for 1 Januari until 31 Desember 2004 and then was validated with data length for 1 January until 31 December 2006. Modeling become optimal after the calibration process with the correlation (R) value of 0,717, volume error (VE) of 3,13%, and the coefficient of efficiency (CE) of 0,89. This showed that the model has a high degree of association with the measured data (0,7Item PENGISIAN KEKOSONGAN DATA HUJAN DENGAN METODE MULTIPLE NONLINIER STANDARDIZE CORELATION PADA STASIUN HUJAN DAERAH ALIRAN SUNGAI INDRAGIRI DAN ROKAN(2013-04-11) Hilwan, Farid; Fauzi Manyuk; Darmayanti LitaMissing rainfall data is a common problem in the practice of hydrology. To complete the missing rainfall data, there are several methods that can be used. Application of a method in a particular location is not guaranteed to produce a satisfactory outcome. For this study, the effectiveness of a model at a specific location is necessary. This study examined the effectiveness and behavior for Standardize Nonlinear Multiple Correlation (MNSC) methods in the implementation of the Watershed in Indragiri and Rokan. For this study, 10 years monthly rainfall data was used. Calculation process was done by making several variations of the simulation analysis of data relating to the condition of filling stations. The results of the calculation will be evaluated by using two categories of errors which are absolute errors and the comparison of statistical parameters of the count data from the original data. The results showed the error evaluation value was greater than that required by the method MNSC less than 25%. Behavior of the model indicates that the data length and sequence of the data does not affect the size of the errors that are generated, and there was no guarantee that a high correlation coefficient between the variable filling station and filled a small error value.Item PERAMALAN DEBIT ALIRAN SUNGAI MENGGUNAKAN METODE MOVING AVERAGE (Studi Kasus Batang Ombilin)(2013-01-09) Hutasoit, Venny M.; Suprayogi Imam; Fauzi ManyukThe main objective of this research is forecasting the river flow in Batang Ombilin.

The problem occurs is the lack of data indicating the level of drought in the region. Therefor, by using the rainfall data in Indragiri watershed, we can obtain an index of drought. Drought index can be used to indicate the drought in the rainfall data series such as drought duration and amount of drought by using the Run Theory. The data used are 25-years rainfall data of Air Molek, Pangkalan Kasai, Sentajo, and Talang Jerinjing Station and 15-years rainfall data of Air Molek, Pangkalan Kasai, Sentajo, Talang Jerinjing, Lirik, Sijunjung, Tembilahan, and Usul Station. The time period used are monthly, 15 daily, 10 daily, and weekly. Rainfall station experienced the highest drought duration and amount of drought for 25 years rainfall data was Air Molek Station, while the lowest was Talang Jerinjing Station. For 15 years rainfall data, the highest and the lowest drought duration for each period of time were in different stations, while the highest amount of drought was in Pangkalan Kasai Station and the lowest amount of drought was in Talang Jerinjing Station. The description of drought duration value and the amount of drought could be found with Golden Surfer 8.0 software. The description of isohyet method between using four rainfall stations and eight rainfall stations shows that the differences in contour value are not very significant.Item STUDI EVALUASI KINERJA PDAM TIRTA KAMPAR BERDASARKAN KEPUTUSAN MENTERI DALAM NEGERI NO. 47 TAHUN 1999(2012-11-24) Hendri; Darmayanti Lita; Fauzi ManyukResult of survey on PDAM Tirta Kampar show that many customers complained of unsatisfactory service. This is due to the performance of taps that are not optimal, so that service to the customer felt also not optimal. This study aimed to find out the problems faced by PDAM Tirta Kampar. Problem analysis is performed to determine the level of success PDAM performance by Kepmendagri No. 47 Year 1999 on Guidelines for Assessment of Regional Water Company. Aspects that affect the performance of taps include: financial, operational and administrative aspects, thus obtained PDAM excellent condition, good, fair, less, and not well. PDAM Tirta performance results shows Kampar success rate simply by weighting the value of >45-60, the value in 2009 was 45.74, and in 2010 was 46.49. Among other causes of low performance is not optimal operational performance, as well as damage to the water meter and the IPA resulted in very big problems of water leakage. For that carried on in an effort to increase the performance of taps as optimizing operational performance and the optimization of human resources. Besides physical action plan efforts through customer water meter replacement, repair IPA, replacement/renewal of piping systems, terameter and providing other support, which is expected to suppress leakage of water so it can improve the performance of the PDAM Tirta Kampar.
