COMPARATIVE MODEL OF MEASURED UNIT HYDROGRAPH WITH SYNTHETIC UNIT HYDROGRAPH (CASE STUDY OF TUKAD PAKERISAN WATERSHED) ABSTRACT Several methods and models of Synthetic Unit Hydrograph (SUH) have been developed to assist in the process of hydrological analysis within a Watershed. These methods include Snyder, Nakayasu, GAMA I, Limantara and ITB. The SUH methods are widely used by practitioners in calculating flood discharge, without knowing the deviations of these methods when compared to measured unit hydrographs in a watershed. This causes the SUH models give an overestimated or underestimated results to the measured unit hydrograph. Therefore, comparative SUH models are needed to determine the deviation of each model, and if necessary adjust the coefficient of the SUH model so that the SUH model approached the measured unit hydrograph in a watershed. Comparative studies of several SUH and measured unit hydrograph were performed on the Tukad Pakerisan watershed in Gianyar Regency-Bali. The measurable unit hydrograph comparisons on the watershed with the SUH Snyder, Nakayasu, GAMA I, Limantara, ITB-1 and ITB-2 models have significantly deviated results. This deviation is shown in three unit hydrograph parameters which include peak discharge (Qp), peak time (Tp), and base time (Tb). The SUH Snyder model with adjustment coefficient Ct = 0.800 and Cp = 1.052 very close to measured unit hydrograph of Tukad Pekerisan watershed with deviation less than 5%.

Urban drainage is one of basic facilities and infrastructure of a town which is cincidered quite important. Agood city needs to consider the condition of the drainage system, because if a settlement is flooded, it will greatly impact the lives of the city. Buildings will be easily damage, environments will be unhealthy and settlements will turn into slumps. The case of flooding is not only in big cities but also emerged in the town of Semarapura that extents only, 5,151 km2. From the conditions on ground, puddles can still be found in some locations, so based on the fact it is necessary to issue reviewing Semarapura drainage system to improve the drainage system in the region. The study in this research has the sense of a systematic search of the drainage problems from an investigation in order to get treatment effort. The approach applied in this research was exploratory and descriptive analytical approach. Data were collected through questionnaires an in-depth interviewers with selected agencies using purposive sampling method. Data analysis was perfomed by descriptive qualitative using likert scale to measure the attidudes, opinions and perceptions of tge performance of the drainage system. The analysis was performed with the aids of SPSS version 20.0, through several stage of the test process to the data sample. The result of the study showed that the influence of the level of maintenance operation, technical management and overall was high at 93,5% with the regression equation Y = -4.874 + 0.405 X1 + 0.228 X2 + 0.089 X3 and the remaining 6.5% was influenced by other factors.

Likert scale used to measure attitudes, opinon and perceptions from the respondents on data analyzed by descriptive qualitative. The research showed resource, subak organization, operational and maintenance generating set, pump, and financial. Work on 82% reaching effectiveness of irrigation management with pump well in Negara district. And, based on result of double linier regression simultaneous and partial, showed that the significant effect to effectiveness of irrigation management with pump well in Negara district, Jembrana regency.

Lakes are one of the surface water resources in Bali Island which supports the socio-economic activities of the community. The growing economic activities either in the tourism or agricultural sector have their effects on the emergence of various problems such as the environmental pollution, shallowness of lakes and erosions. The emergence of various pollutions and the decreased functions of the Lake Beratan is not separable from the intervention of the community living surrounding the lake so that the conservation efforts need the community participation living surrounding the lake. This is based on the idea that the success of the conservation of water resources does not only depend upon the government but the involvement of the community also becomes a key factor. This study aims to identify and analyze the participation of the community living surrounding the Lake Beratan in the conservation of water resources. The number of samples used in this study was 98 respondents gathered by means of purposive sampling in the village of Kembangmerta, the village of Candikuning I and Candikuning II which are located close to the area of Lake Beratan and the majority of the people there use the lake water for daily needs. The community participation is divided into two categories, less participations and good participations, calculated based on Likert scale while the effect of free variables such as age (X1), education (X2), income (X3), length of living (X4), and perception (X5) on bond variables were calculated using discriminating analysis. The result of the study shows that the community participation surrounding Beratan Lake in conserving water resources had been good. The differentiating variables were the age of the respondents and their incomes.

lack of Subakparticipation as a water user farmer association (P3A) and the Government of the Operation and Maintenance of the irrigation network which resulted in disruption of the network as a whole. In line with this, one of the activities to be carried out is the rehabilitation of Irrigation network in the River Basin of Empas-Sungi especially in GadonIrrigation Area in Tabanan on the activities of DISIMP II (Decentralized Irrigation System Improvement Project in Eastern Region of Indonesia Phase II), which aims to restore and improve the functions of network facilities and irrigation.The study was conducted on Gadon D.I Watershed of SungiRiver with explorative methods, that is, studying and evaluating DI Gadon on the Watershed of Sungi River, by conducting interviews with members of Subak and relevant agencies. 73 respondents were selected based on purposive sampling method to measure attitudes, opinions and perceptions of Subak and the Government using Likert scale. Data were analyzed using descriptive qualitative methods and Linear regression to determine the role of water control system and the government against the post-construction operation and maintenance of infrastructure of DISIMP II in Gadonirrigated areas in the watershed of Sungi River in Tabanan Regency.Regression analysis showed that the Government had shown a greater role withthe beta standardizedcoefficient value of 0.499 (49.9%), followed by the role of Subak / P3A amounting to 0.344 or 34.4% of the Operations and Maintenance while 15.7% was influenced by factors that had not been included in this study. In this study, Subak / P3A had the participation or role lower than the participation of the government. The results also showed that the increase in government participation and Subakwill improve the operation and maintenance of the irrigation network of post Infrastructure Development of DISIMP II either partially or simultaneously. Keywords: Participation, SubakGadon, Government, Operations and Maintenance.
