Abstract

   Many synthetic unit hydrographs have been developed including the Nakayasu Synthetic Hydriograph based on empirical observations in Japan. Although the determination of parameters has been presented with various criteria, so far the results are still relatively distorted if applied to watersheds in Indonesia, so it is necessary to calibrate some of the parameters used.   This research is a research study conducted in 3 sub-watersheds in South Sulawesi Province by using a type of spread, namely the Maros sub-watershed, Tallo sub-watersheds and Jeneberang sub-watersheds. There are 2 parameters to be calibrated, namely the coefficient α and Ctg with tg = 0.04-0.0058L, the calibration done is obtained α and Ctg values corresponding to each watershed.   The results of the study indicate that the use of the Nakayasu method for the purposes of the analysis of flood hydrographs which is a change in the variety of rainfall data in Indonesia, needs to be modified, especially to the parameters used. To get a range of parameters based on the parameters of watershed characteristics, it is necessary to conduct further studies on many watersheds based on the type of watershed.

Abstract

This study aims to analyze the parameters that influence the Snyder synthetic unit hydrograph method. The study was conducted on 11 watersheds in South Sulawesi Province, 8 watersheds for modeling and 3 other watersheds for reliability testing (model verification).     With rainfall data, the discharge data and watershed characteristics obtained from each watershed were analyzed for parameters that affected the hydrograph breakdown of the Snyder HSS method. Then compared to the hydrograph of the observation unit which was analyzed by the Collins method.     After calibration was done with the NASH criteria obtained Peak Time (Tp) = 97.996%; Peak Discharge (Qp) = 98.331% and Basic Time (Tb) = 99.700%. The curved delineation of the hydrograph uses the auxiliary point W, which gives the result of volume deviation, namely: 7.980%, 9.227%; 6.855%; 4.966%; 10.972% and 9.843% are relatively small when compared to the model using Alexejeyev Arch with deviations: 22.362%; 29.991%; 26,319%; 19.602%; 29,786% and 17,633%.

Abstract

Provision of water is very important to support optimal crop yields. However, in some areas there is a problem with not meeting the needs of the rice fields with the available discharge, this is due to several reasons, one of which is the loss of water along the channel during the journey to the rice fields. This study did not review and analyze sedimentation, this study only covered irrigation areas in the primary, secondary and tertiary canals of the Mencongah irrigation area, the type of layer was only limited to soil and concrete.From the results of the study, it was found that the efficiency difference in the channel that had been given a layer of concrete with the channel that had not been coated with concrete, which was obtained for the primary channel of 99 % efficiency, 97% of the secondary channel, while the layer which had not been coated with concrete was the tertiary channel of 87% efficiency.

Abstract

The existence of Jalan Pendidikan connects Mataram District with Ampenan District. The comfort and safety of road users really need to be considered in accordance with the initial planning for the construction of the city road. The increasing number of vehicles that pass every day and the influence of the weather have caused some parts of Jalan Pendidikan to be damaged. This research was conducted to find out the damage that occurred and the activities that needed to be done to improve the condition of the damage.The research method used to determine road damage and the steps taken in road maintenance are the Bina Marga and LHR methods. The survey data for the length of Jalan Pendidikan is 1,570 km. The road is divided into 5 sections with each section being 314 meters long. This division is carried out to determine the condition of the damage more thoroughly. The data is analyzed to determine the value of road damage based on the bina marga. Traffic data collection is carried out to determine traffic density so that the LHR value of the road is obtained. Furthermore, the value of the road class is determined based on the LHR. With the formula UP = 17 – (LHR Class + Road Condition Value) it can be determined the Priority Sequence carried out in the maintenance of Jalan Pendidikan.The results of the research on Jalan Pendidikan, there was light damage on sections 3 to 5 or km to 0.628-1,570 km needed periodic maintenance. Meanwhile, parts 1 and 2 are still in good condition so that the action taken in road maintenance is routine maintenance.

Abstract

Hydrological analysis is the most important measurement in determining runoff in order to find ways to overcome flooding. The flow rate that is the basis for calculating flood control and protection is the planned flood flow rate obtained from the sum of the volume of rain runoff and the flow rate of the water catchment area in question during a certain return period. This research is a case study using rainfall data for 10 years, namely 2014-2023. Rainfall prediction is an estimate of the amount of rain that will fall in a river basin. There are several methods for determining annual rainfall, the Gumbel distribution method, Pearson log type III, and the normal method. After analyzing the annual rainfall data obtained at the West Lombok Regency Meteorology, Climatology and Geophysics Agency office, using three methods, namely the EJ Gumbel method, the Log Person Type III method and the Normal method, where from the three methods the maximum rainfall difference was quite large, In the following table you can see the difference in the amount of maximum rainfall in the return period T years.
