Abstract

This study analyzes the potential and operational planning of the Tabulahan hydropower plant located at the Bonehau River, Periangan Village, Tabulahan District, Mamasa Regency, West Sulawesi. The project utilizes a water catchment area of 306 km² upstream of the dam and 324 km² downstream of the plant. The discharge analysis uses the Flow Duration Curve (FDC) method with the results showing adequate discharge availability. A reliable discharge of 22.80 m³/s was selected based on a reliability level of 85%-90%, with a design discharge of 8.97 m³/s for each turbine. For further planning analysis, the power generation discharge was set at Q50% (14.72 m³/second) and the river maintenance discharge (ecoflow) at Q95% (21.60 m³/second). With an installed power capacity of 10 MW, the Tabulahan hydropower plant is designed to optimize the potential of water resources with a sustainable approach.

Abstract

Hydrological data is the data that became the basis of planning activities Water Resources Management (SDA) in the river area, such as irrigation building planning, water building, river management, flood control and others. Therefore, hydrological data needs to be managed into a geographic information system to provide accurate, true and timely SDA information for all interested parties. By knowing the position of climate observation post and rain station along with the climatic and rainy data, which can be observed by the public, it is expected that the control over the implementation of development can be done more openly. The results obtained from this research are digital map position of observation post along with climate data, water level and rainfall along with South Sulawesi Province that can be used by public, government, and educational institution that need location of station position and data recording climate observations, water levels and rainfall in South Sulawesi.

Abstract

The tools and methods used in the measurement of water flow velocity are now very diverse, such as by using Venturi Meter, Orifice, Current Meter, Pitot Tube, and so forth. To learn more about water flow velocity measurement method, in order to improve professionalism in the field of water resources can be done research at Hydraulics Laboratory by researching Water Flow Analysis by Using Pitot Tubes. The research process will be carried out using three varied channel basis samples: reviewing the velocity of the water flow at the bottom of the channel with slippery base, reviewing the flow rate of the water on the gravel base channel, and reviewing the flow rate of the water on the channel with the decking concrete base. The expected result of this research is knowing the distribution of velocity in a cross section such as drainage channel, irrigation channel and river, so construction of water structure can be adjusted position placement in the open channel section. In addition it can be used as a reference in planning an open channel. One of the benefits to construction cofferdam construction speed distribution is to determine the dewatering system to be carried out during construction.Keywords— Flow Speed, Speed Distribution.

Abstract

The purpose of the research is the determinationof Irrigation water requirement based on primer datas collectingand analysis factors of land preparation, plant growth,determination of water loss due to percolation. Irrigation waterrequirement depends from various factors in the preparation ofthe land, plant growth, determination of water loss due topercolation, the determination of the replacement of water andrain layer effectively. The availability of irrigation water iscalculated based on discharge data retrieval on the TaroangSecondary channel. which then processed to obtain the finalresult of the availability of water in the channel. Results of thestudy shown that needs water to irrigate an area of secondarychannels Taroang covering an area of 2,140 Ha as much 39.11m3/s. While the availability of water that goes into the secondarychannel taroang where discharge a minimum of 0.12 m3/s and themaximum discharge of 0.31 m3/s.

Abstract

The purpose of this research was to determine the surface runoff and the puddle  in the of flood risk area in Manggala village. Modified Rational Method had been applied to determine runoff discharge. While, flood risk areas were based on the map from National Disaster Management (BPBD Kota Makassar, 2014). Rainfall data of Manggala village wascollected from 2009 to 2018 from three stations, they areBiringRomang, Panakukkang, and TamangapaKassi. Therefore,  a Thiessen method had been applied to determine the rainfall area.Research results shown that runoff discharge for return period 5 years was185.38 m3/s, with height around 0,50 to 2,00 m.

Abstract

The community, both individuals and groups, need water for daily and other needs. From the various types of needs, the water for drinking water is a top priority, above all other necessities.Excessive exploitation of groundwater that exceeds the ability of aquifers to provide groundwater due to competition for various interests can cause a continuous decline in groundwater level and will certainly reduce the potential for groundwater availability in the aquifer. In this research, the potential of groundwater in Jeneponto’s aquifers in several locations is examined using in situ pumping test. From the pumping test results, it is known that the potential of groundwater reserve in Jeneponto Regency is quite significant and is spread in several districts with a minimum discharge supply of 4 litres per second. However, some procedures must be taken to protect the availability of groundwater in the regency from the technical aspects for example the determination of pumping location, the depth of groundwater pumping and the maximum pumping discharge allowed, and also all steps that support groundwater recharge.

Abstract

Cabenge River is part of the WalanaeCenranae River area in Soppeng Regency. Annually, the area around the Cabenge River gets the most losses from floods, both in terms of facilities and infrastructures. This study aims to map the areas prone to flood and flood risk, based on the field that gets the most significant impact. This study uses a Geographic Information System (GIS) as a tool and ArcGis Software in determining the level of vulnerability and risk of flooding at the study site. This type of research is a combination of mapping (topographic results) and map analysis. The variables used are DEM (Digital Elevation Model) data and flood volume. The data processing technique used is the GIS-based inundation model approach using inundation height (H) based on a comparison between the volume of water (V) in inundated areas and the volume of water (Q) of flood sources. The results showed that Lilirilau District was in the high hazard class with an area of 100 km2 and had the biggest impact, while in Liliriaja District, the area that was in a high hazard class was 34 km2 and Ganra District was 21 km2.
