Tukad Mati is one of the rivers in the province of Bali that unfolds and flows in Badung regency and Denpasar. Inundation due to flooding is a problem that often occurs in this region during the rainy season. In an effort to overcome problems of flooding have been many studies carried out so as to produce flood control alternatives such as normalization, diversion channels and retarding basins. Retarding basin is one of flood control alternative that has not been much studied. In this study conducted a simulation of flood prevention alternative with retarding basin at Tukad Mati, by the hydrology approach method and hydraulics using HEC-RAS 4.0 program applications. Simulations performed on the current river flow conditions (existing condition) and to the existing conditions with the retarding basin, according to the detail design of retarding basin in the city of Denpasar and evaluate the effectiveness of the retarding basin in the river basin flood control of Tukad Mati. Flood control by retarding basin based on simulations with the 2 (two) years flood return period, resulting in a reduction of water level by an average of 0.42 meters or an average of 12% of the maximum water level in the conditions without retarding basin, which occurred in along the grooves on the lower reaches of the retarding basin and inundation waters still occur in some places, particularly in the downstream of Umadui Dam. Economic analysis of both the analysis of Benefits/Cost produces a parameter of BCR, NPV and IRR are not meet the feasibility requirements. The effective retention of retarding basin based on simulation results are 282,630.00 m3 with the ability to flood accommodate for 3-4 hours. In terms of economic development retarding basin is not feasible in terms of comparative costs and benefits

RISK MANAGEMENT AT THE CONSTRUCTION STAGE OF IMPROVING THE IRRIGATION NETWORK OF THE SUNGI RIVER WATERSHED AREA IN TABANAN REGENCY ABSTRACT The implementation of irrigation network improvement project in Sungi River Watershed is quite complex because it is related to water regulation system by water user farmer association (subak). In the implementation there are various risks that may affect the cost, quality and timing of the project. The purpose of this study was to identify risks, assess and determine the acceptance of risk, determine the dominant risk and mitigation actions and risk ownership for the dominant risk. The research was conducted in the Irrigation Areas (IA) of Cangi, Bunyuh, and Baru Kedokan with a combination method (quantitative and qualitative descriptive). The data collection was done by distributing questionnaires to respondents directly involved in the project implementation. The number of respondents was 20 people and selected by purposive sampling. The results showed identified risks of 36 risks with 14 risks of previous research outcomes and 22 risks from brainstorming results. The risk assessment and acceptance results were categorized as undesirable 52.78%, acceptable 33.33%, negligible 13.89%, and no risk was found in the category of unacceptable. Mitigation was conducted on the undesirable risks by making changes to the initial design plan in accordance with the field conditions, intensifying the implementation of the supervision in the field and carrying out the work in accordance with the operational standards and procedures contained in the contract. The ownership of risk was allocated to the parties involved in the project implementation including job owners 8 risks, supervisory consultants 9 risks, contractors 16 risks and farmer community 1 risk. The undesirable risk should be the concern of the parties involved in the project so that the final results of the work were in accordance with quality, cost, and time planned.

Karangasem regency is one area of dry areas in the province of Bali. This area has limited surface water resources in some area, and the rivers are partly a intermittent, which there is no water in the dry season, so as to meet the needs of raw water is very difficult. One alternative to overcome this, the government has built the small reservoir, called the Embung. In order to meet the embung system sustainable, the participation of water users in the operation and maintenance of Embung is required. This research aims to determine the influence of human resources (HR) factors, funding, ideas and effort, and organization in the operation and maintenance of Embung. Number of samples obtained in these research as many as 290 respondents is calculated by Slovin theory formulation of the total 1.045 family heads of water user population. Community participation is measured statistically using the independent variables, namely human resources (X1), funding (X2), ideas and effort (X3), organization (X4), as well as the operation and maintenance of embung as the dependent variable (Y). Data results of the questionnaire, scored into a Likert scale, further processing was carried out by multiple linear regression analysis. using statistical software Statistical Package for Social Science (SPSS) version 19. The results showed that there is participation of water user in the operation and maintenance of embung in the regency of Karangasem, which can be shown from the resulting regression equation model, where all the regression coefficients of each variable are positive. Independen variables also have a significant influence on the dependent variable, with Fhitung (= 2316,926) > Ftabel (= 1,96). While the most dominant variable effects on the operation and maintenance of embung is organization's variable, with the ? value of 0.382, followed by ideas and effort variable (? = 0.329), proceeded by funding (? = 0.302), and the lowest is the human resources (HR) variable (for ? = 0.283)

One of the strategies to fulfil the needs of raw water in Tabanan is to plan for utilization of Wellspring of Metaum as a source of raw water. Before deciding to take the spring water source of Metaum as raw water, it was indicated the potential failure of either the pre-construction, the construction and the post-construction for example in the management of groundwater abstraction permits and the determination of trace pipeline network. The risk analysis was conducted on the plan to use the Wellspring of Metaum in Marga village of Tabanan, descriptive and qualitative methods. Data were collected through questionnaires that distributed to 28 respondents based on purposive sampling method. The result showed that there were 44 risks in the utilization plan of Wellspring of Metaum. These included 14 unacceptable risks, 24 undesirable risks and 6 acceptable risks. This indicated that the utilization of Wellspring of Metaum has a high level of risks, especially for the unacceptable categories and the undesirable risk categories. The mitigation actions that should be performed were dissemination and lobbying to the religious leaders / people directly affected as well as a limitation of protection for the sacred area. While mitigation action for the undesirable risks can be conducted through dissemination and personal approach through district level officials, village or neighborhood small units directly affected. The risk ownerships of the unacceptable risks were the Local Government / Central Office / Central River Region of Bali-Penida, Consultant / Contractor and the people. For the risk taker of the undesirable risk category are the Local Government / Central Office / Central River Region Bali-Penida, Consultant / Contractor and the people. Keywords : risk analysis, Wellspring of Metaum, Mitigation, Risk Ownerships.
