The accuracy of hydrological data is influenced by the method, operator/observer, and the performance of the measuring instrument. Until now, Water Resources Management Agencies in Indonesia conducted observations of discharges in rivers or channels indirectly, by observing WL (Water Level) in the WL Gauging Station. WL values can be read directly and manually or using an Automatic WL Meter Tool (AUTO) which has been found in many types. Whatever the type, it is necessary to evaluate its performance, one of which is through calibration trials in the laboratory. This paper presents an evaluation of several types of AUTO (AWLR, AWLL Buoyance, and AWLL Pressure) using a Calibrator in the Laboratory. With calibration can be compared the results of WL readings from AUTO with the Standard/Reference Tool using the Calibrator as the main facility, so that the value of the Measurement Error and Measurement Uncertainty is obtained. Both parameters are used to determine the performance of a device because it is related to the level of accuracy and precision. Based on the results of the test, it was found that both the best level of accuracy and precision in sequence are AWLR, AWLL Pressure, and AWLL Buoyance.","PeriodicalId":356205,"journal":{"name":"JURNAL TEKNIK HIDRAULIK","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128480170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The treatment should be directed to comprehensive changes of management paradigm for all aspects in it. Those were indicated by the increasing of disasters around the watershed, such as floods, droughts, landslides, erosion and increased of sediment transported by the river basin. The increasing of sedimentation which occurs in the river flow will disrupt the performance of existing hydraulic structure in the river. The event could be monitored by hydrological data, especially with the continuously and accurately of discharge and sediment data. In order to solve the problem, sediment data quality control model was needed. The purpose of this research is to determined suspended sediment data quality control model, in order to have continuous and quality guaranteed of sediment transport data. The scopes of this sediment data quality control were making criteria and sub, determining rank priority between criteria and sub, arranging scoring form, trial and error, finalization. The model consists of three main stages, there are measurement of discharge and taking sediment sample (QC1), drawing of sediment rating curve (QC2), and conversion of discharge data to sediment transport (QC3).","PeriodicalId":356205,"journal":{"name":"JURNAL TEKNIK HIDRAULIK","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125956283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The extraction can be done by drilling, damming water, and pumping. Management of the potential of raw water in an area is determined by geographical and geological conditions. One of the occurrences of springs found in coastal areas is influenced by marine and geological parameters which will further affect the method of capture, management, and utilization. This prototype of raw water supply has been installed in a location around the spring at Banyu Asri Beach, Singaraja City, Buleleng Regency, Bali Province in 2013. Data collection methodology is carried out by observing the wave data, pumping discharge and water salinity. These observations were made for two types of oscillation boards, namely using wood and fiber. From this technology, it is expected that the supply of a stable source of springs and the mineral content that is maintained even though the position of the spring is strongly influenced by the tide of the sea water which often inundates the discharge point of the spring. The spring at Banyu Asri Beach has been widely used by the community for drinking water and ritual worship. From the results of the performance of the prototype after being installed at the location of the spring, it has shown the ability to drain fresh water through pipelines towards the land, although the wave height that occurs in very small locations ranges from 0.10 to 0.30 cm and the discharge flow is up to 0.03 L / sec.","PeriodicalId":356205,"journal":{"name":"JURNAL TEKNIK HIDRAULIK","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128413543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dranage construction will be followed by subsidence of peatland . To be able to extend the chance to get profit in the plantation business subsidence prevention efforts are needed. Setting water level and the prevention of excessive drainage is one of the efforts to reduce the rate of subsidence of the peat.This study is based on literature review by collecting information from various sources and then comparing and analyzing it so that information is obtained on a comprehensive subject matter. Literature review include: monitoring parameters, types of equipment for monitoring, pattern placement monitoring equipment, the range and the frequency of monitoring. From the study concluded that the water level necessary to measure on land and channels using dipwell and staff gauges. Observations were made with a combination of automated recording device and manual recording. Both are quite accurate, but the use of automatic registers in remote locations saves time, and if an automatic device is installed in an area that has the potential to have large water level fluctuations and runs quickly, it will provide more accurate data. Observations on dams for water level control are installed at every 20 cm drop in hidraulic head.","PeriodicalId":356205,"journal":{"name":"JURNAL TEKNIK HIDRAULIK","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116372401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
