s. Management of water for irrigation in Bali has been exist since the IX century, which is known as Subak. Subak is traditional irrigation system and it is closely associated with the principle of TriHitaKarana. The elements and facilities of subak include: irrigation networks, organizational structures and regulation. Distribution of water uses a comparison unit called ayahan. One unit of ayahan entitled to one tektek or one kecoran which is a unit of water flowing through the cross section of traditional spillway on a countinuous basis. If water availability is limited, then water supply is managed by rotation basis called pergiliran or nyorog system that based on different planting time. The principle of nyorog is the upstream section get water first (called ngulu), the midstream obtain water after the upstream had finished cultivating of soil (called maongin), and the downstream called ngasep. In rainy season, rice planting is simultaneously done in all area of subak, which is called kertamasa. Meanwhile in dry season called gadon, rice planting is scheduled by principles of nyorog or rotation. The arrangements of water resources and the settings of cropping pattern is stated in regulation (awig awig). Water distribution were managed ​​by the administrators of subak within the territory, or through an agreement between the territories’ administrators. The Sedahan and Sedahan Agung, whom in charge as subak’s adviser have very important role in the coordination on management and use of water. Recently they are facing uncertainty in existence, and causing lost of coordination in resolving various problems. In the future, the functioning of the Sedahan and Sedahan Agung is needed.

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.

Subak irrigation systems have been well known since the ninth century. These systems are managed by a Subak association based on the Tri Hita Karana philosophy, as a faith of Balinese Hindus based on harmony between human beings and God, harmony between people and nature, and harmony between people and people. This philosophy underlies every activity of Subak farmers. To manage Subak systems, Subak associations and farmers pursue the Subak regulation called Awig‐awig Subak as the togetherness consensus that was originally announced by the King and nowadays by the Head of the Regency. As associations for irrigation system management, Subak associations have been already naturally adapted to participatory irrigation management (PIM). This paper has been prepared based on a literature study to portray centuries of experience with ancient Subak irrigation system management, in which PIM was represented by three linked aspects: PIM in irrigation system operation and maintenance; PIM with respect to socioculture and economics of agriculture; PIM in light of a religious community. While several of these systems are now under stress, the results of this literature study may hopefully contribute to sustainable PIM for the operation and maintenance of irrigation schemes in Bali during the forthcoming decades.

Abstrack : Jembrana Regency especially Negara District have two river caracteristics such as the river which located in western Melaya River only flow when the rainy season and the rivers located between western Klatakan river and eastern Pulukan river flow every years with low discharge. it caused failing of harvest. So the ground water used to supply the surface water needs. But, complaint comes from the farmer caused by the expensive cost of operational generating set. The approach doing by study and research directly to the well pump which located in Negara district. Purposive sampling used  to determine the respondents in this quisionaires. 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.

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. From the equation it can be seen that the maintenance operations were more dominantly affected on the performance of the drainage system in Semarapura town District of klungkung compared with management and technical. The effort carried out to increase performance system of Semarapura town drainage network is to construct a structured system of maintenance operations so that it can be performed on a regular basic, establish drainage management institutions that it’s authority and responsibility can be coordinated as directed an make clear rules of management system, make repairs damage drainage infrastructure in accordance with the technical requirement.
