Abstract

One of parameters to determine the discharge is to know the pattern of rainfall distribution. To calculated the rainfall distribution is required hourly rainfall data of TRMM. Rainfall distribution patterns can be calculated using the empirical method of Alternating Block Method (ABM), Tadashi Tanimoto and Mononobe. The aim of this research to determine the pattern of rainfall distribution in the city of Pekanbaru from 2009 to 2016 based on the pattern and correlation. Based on shape, the most common TRMM distribution pattern is the bell shape that occurs from the duration of 3 to 9 hours and for the duration 2 hours has the form of a declining ladder. While based on correlation, pattern of rainfall distribution for duration of 3, 4, 6, and 7 hours tend to ABM Method, 5 hour duration tends to Mononobe Method and 8 hour duration tends to Tadashi Tanimoto Method. The results of this study have been compared with previous studies for Pekanbaru City, which of the two studies only rain with duration of 3 and 5 hours that have a match pattern.Keywords : The Pattern of rainfall distribution, Satellite rainfall data, Alternating Block Method (ABM), Modified Mononobe, Tadashi Tanimoto

Abstract

The construction project is an activity which has a goal to be achieved. In the construction process, the cost is the major consideration because it commonly involves a large amount of investment and is vulnerable to the risk of failure. The purpose of this research was to determine the rate of validation, and to analyze the most dominant factor causing the overrun of construction costs (case study on Municipal Projects in Pekanbaru). The collected data were analyzed by using validation and reliability test, factor analysis, classic assumption test, and multiple linier regression. The data processing was done by using SPSS software (Statistical Product and Service Solution) version 23. As a result, it is obtained that the most dominant factor which has triggered the overrun cost consisted of: planning and construction department i.e. handling too many projects at the same time with the percentage of 83,9%, part of the cost estimate that does not take into account the unexpected cost with a 92.0% percentage on the road, part of the cost estimate that does not take into account the unexpected cost with a percentage of 90.1% on the bridge.Keywords : construction, cost, overrun cost, dominant factor.

Abstract

Wastewater of commercial areas such as hotels, shops, restaurants, offices, and shopping centers relatively contain high pollutant concentrations, they caused the imbalance of drainage ecological quality, health problems, and the water pollution itself. The effective technology in treating waste wateris The Sub Surface Flow Constructed Wetland (SSF-Wetland) that maximize either the impact or the potentcy of the plants in treating waste waterin the physical, chemical and biological wayby using plants/vegetation, water and microorganisms to reduce the level of pH, Chemical Oxygen Demand (COD), and the level of Total Suspended Solid (TSS) contained in waste water by slowly flowing them through the inlet hole to the surface covered by the living plants. The experimental result shows by using bamboo water plant (Equisetum hyemale) in artificial wetland system, the content of pollutants in wastewater can be eliminated. The highest average value of COD reduction efficiency is 61.9 %, 92.6 % of TSS and the decreasing of pH reaches 29.4%. The advantage of wastewater treatment using this system enables us to produce the appropriate water quality of the domestic wastewater based on the quality standards.  Keywords:Equisetum hyemale, SSF-Wetland, wastewater

Abstract

Kampung Sungai Tengah has a productive rice field area of about 450 ha. The extent of rice fields is a potential that can support food availability to meet local and regional needs. The government provides long storage to meet agricultural irrigation water needs, but the quality of crop yields is not maximized and land conversion still occurs. This is caused by difficulties in providing irrigation water due to the absence of pumping development from the government and the lack of understanding of farmers about the function of long storage. In addition, the elevation of the water table during the dry season is lower than the elevation of the rice fields. This research was conducted by using various secondary data and analyzing the feasibility of constructing irrigation pumps in the rice fields of Kampung Sungai Tengah. Based on the data analysis, it was found that the availability of reliable discharge (Q80) of the Siak River using the F.J Mock methods was 147.48 m3/s with the largest irrigation water requirement in April period I of 0.88 m3/s. With a very high level of water availability compared to the irrigation water needs of the area, technically the construction of irrigation pump is feasible.Keywords: Irrigation, Irrigation pump, Feasibility, F.J Mock methods

Abstract

Rainfall distribution is one of the parameters required for calculations of the design flood. The pattern of rainfall distribution is the mean of rainfall expressed in a graph that describe time function to variation in depth of rainfall. The pattern of rainfall distribution is obtained in two method, empirical method and averaging hourly rainfall data. The rainfall data used is obtained from TRMM JAXA in eight years (2009-2016) for Kampar Regency. In this research, the approach of distribution form between empirical methods with the hourly rainfall data average of TRMM to simplify the acquisition pattern of rainfall distribution. The empirical method used is Alternating Block Method (ABM), Modified Mononobe, and Tadashi Tanimoto. Based on TRMM rainfall data, that rainfall duration was dominated by one hours rainfall events. The analysis results for pattern of rainfall distribution approach of TRMM JAXA with empirical method shows that designed rainfall duration (3 to 8 hours) tends to approach Alternating Block Method (ABM) pattern.Keywords: Rainfall distribution, satellite rainfall data, Alternating Block Method, Modified Mononobe, Tadashi Tanimoto
