Abstrak :. Air minum merupakan kebutuhan dasar bagi manusia sehingga menjadi hal yang wajar jika sektor air bersih mendapat prioritas dalam penanganan dan pemenuhannya. PDAM sebagai perusahaan daerah pengelola air minum seharusnya mampu untuk memenuhi kebutuhan tersebut. Penggunaan air minum di masyarakat yang tergolong tinggi menyebabakan perlu dilakukannya perubahan tarif dasar air minum. Ini bertujuan agar masyarakat lebih bijak dalam penggunaan air minum ini. Tujuan dari analisis ini adalah untuk mengetahui penggunaan air rata-rata sebelum dan setelah dilakukannya kenaikan tarif PDAM. Selain itu juga untuk mengetahui besarnya penggunaan air rata-rata per orang per harinya. Metode yang digunakan adalah dengan menentukan beberapa sampel pelanggan untuk setiap golongannya, dan mentabulasikan data penggunaan air minum setiap tahunnya dari sampel yang ditentukan. Berdasarkan analisis yang dilakukan dari data penggunaan air minum pelanggan PDAM Kecamatan Denpasar Selatan, terjadi perubahan total penggunaan air minum per tahunnya untuk setiap golongan pelanggan. Sementara itu rata-rata penggunaan air setelah dilakukannya kenaikan tarif 60% sampel pelanggan yang diambil mengalami penurunan penggunaan. Untuk rata-rata pemakaian air minum per orang per harinya di Kecamatan Denpasar Selatan mencapai 232,15 liter per orang per harinya dengan asumsi 1SR = 5 jiwa) . Dimana pemakaian tersebut di atas rata-rata penggunaan yang ditetapkan pemerintah sebesar 130 liter per orang per hari untuk kota besar. Maka penggunaan air minum di Kecamatan Denpasar Selatan masih terbilang tinggi. Tingkat kebutuhan akan air minum di masyarakat, dipengaruhi juga oleh faktor perekonomian dari masyarakat itu sendiri Abstract: Water is a basic need for human si it became fair in the water sector acquire priority in handling fulfillment. PDAM as a local water management company should be able to meet those needs. The highly used of water in society caused basic water tariff changing. The purpose to make people wiser in using water. The aim of this analysis is to determine the average water usage before and after the increase of PDAM tariff. In addition, to know the average water usage per person per day. The method is to define multiple customer samples for each faction, and tabulatingthe data usage of water each year from yhe specified sample. Based on the analysis of PDAM costumer water usage in South Denpasar District, a change in total water usage per year for each class customer. Is happen, the average water use after doing 60% rate increase, The water usage is decrease. For the average water consumption per person per day in South Denpasar District reached 232.15 liters per person per day assuming 1SR = 5 people). Where the usage is above the average usage set by the government is 130 liters per person per day for a big city. So the use of drinking water in the District of South Denpasar still fairly high.The level of demand for drinking water in the community, influenced also by the economic factors of the community it self

The three stars hotel occupation in Bali is unpredictable compared to other luxury hotels. However the average length of stay at the hotel of this level is higher than the other five-star hotel. Both types provide opportunities and risk to investor, thus, that investor need to conduct broad examination before do some investment, especially to identify risk factors for investment. This paper presents comprehensive risk factors of investing in three star hotels in Bali. Data obtained from structured interview to the tourist of the various levels of tourism management in Bali. The data ware processed using a descriptive qualitative into three major groups namely the major risk, unacceptable risk, and undesirable risk. The results of this study indicate that there ware 40 types of investment risk on a three-star hotel in Bali. Amongst the 40 types of these risk, only 25% was acceptable risk and negligible risk, while the rest categorized major risk. Between the major risk, 50% was unacceptable risk and the remaining 25% was an undesirable risk. Unacceptable risk were classified into risk occurs more often in pre-design activities which mainly related to marketing activity, even as the dominant risk was the environmental problem, especially with the traditional village-awing awing (local village regulations). Risks a classified as undesirable risk were more common in the activities during the operation of hotels, which are generally triggered from the human risk.

The Saba river basin has an area of ??69.54 km2 and the length of the drainage is 36 km. The river drainage area is a hilly area, so that rainwater flows quickly which then becomes a flood. The land condition in the inundation area generally consists of rice fields that depend on rain, there is no technical irrigation system so that the cropping pattern depends on the rain. So to overcome this problem a Titab Reservoir was built. The Titab Reservoir serves as the supply of irrigation water for DI Saba with an area of ??1,396.40 ha and Pulp of 398.42 ha, raw water as much as 0.35 m3/s and PLTA with 2 x 0.75 MW. Given the importance of the benefits of the Titab Reservoir, a study of the reservoir capacity of the Titab Reservoir was conducted. The analysis begins with calculating the reliability discharge from measured discharge data, obtained Q80 of 2.01 m3/dt. Furthermore, calculating irrigation needs, while water and hydropower needs are used from existing planning data. Then do the simulation using the RIBASIM program. The simulation results show scenario 2 produces a reliability level of 83.33%, scenario 3 produces a reliability level of 82.22%, and scenario 4 produces a reliability level of 58.54%. Scenario 2 is the optimum result. Furthermore, verification of the RIBASIM model is needed using observational discharge data at the Saba dam. The verification results show that the data accuracy is quite good with a correlation coefficient of 0.74 and determination of 0.55.

RISK ANALISYS OF DEVELOPMENT AND MANAGEMENT OF GARBAGE PROCESSING FACILITY 3R (REDUCE, REUSE, RECYCLE) IN DENPASAR CITY (CASE STUDY OF GARBAGE PROCESSING FACILITY 3R SANUR KAUH VILLAGE)ABSTRACTThe implementation of 3R Garbage Processing Facility in Denpasar City still encounters various obstacles and constraints in its development until it failed in its management, therefore this study aims to analyze various dominant risks that can hinder the development process and management of 3R Garbage Processing Facility so that in the future the development and management of 3R Garbage Processing Facility will be better prepared to anticipate and mitigate the risks that may arise. This research is a case study conducted in the 3R Garbage Processing Facility in Sanur Kauh Village, located in the City of Denpasar. Risk identification in this study was obtained by brainstorming methods, study reports on development activities, observations to locations, and interviews by using questionnaires to those who have competence and direct involvement in the construction and management of the 3R Garbage Processing Facility in Sanur Kauh Village. The results of the study obtained 80 (eighty) risk identifications consisting of: 8 (eight) extreme risk categories, 43 (forty three) high risk categories, 25 (twenty five) moderate risk categories, and 4 (four) low risk categories. The dominant risks were extreme and high risks totaling 51 (fifty one) risks. The dominant risks include the difficulty of mobilizing the community to sort garbage from the source, the issue of dissemination of development to the community, the pros and cons of developing 3R Garbage Processing Facility, obstacles to the formation of KSM (Self-Help Groups), obstacles to preparation of shop drawings and procurement documents and services, operational cost deficits, shortages of human resources, problems with the accumulation and sorting of garbage, and difficulties in obtaining customers. Risk mitigation is, among others, cooperation between the KSM (Self-Help Groups) and the government of Sanur Kauh Village in overcoming the issue of dissemination to the community, financial solutions and the availability of human resources. The allocation of risk was mostly found on KSM (Self-Help Groups) by a percentage of 84.31%.

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

Many potential water of Unda river waste into the sea that indicate the management of irrigation network is still less. The lack participation of stakeholders from the government and the public in this case Irrigation Area of Unda river seen from the number of the irrigation channels damage and existing buildings. The approach used in this research is explorative and descriptive approach. The collecting Data obtained by questionnaires and in-depth interviews with stakeholders were selected using purposive sampling method. Data were analyzed with descriptive qualitative Likert scale used to measure attitudes, opinions and perceptions of stakeholders in the securement and maintenance. The test results show the value of the adjusted R Square is 0.747. This mean that stakeholders have 74.7% effects, while 25.3% is influenced by other factors. Which is government contributes most, followed by Subak / P3A. It caused by the influence of the test simultaneously or partial value of Fcount > Ftable, so it can be concluded participation of stakeholders have a significant influence on this operation and maintenance of irrigation system in Unda Irrigation area in Klungkung district either simultaneously or partially. This means increased participation of stakeholders simultaneously and partially will improve the operation and maintenance of irrigation networks. From this research can be given some suggestions. In order for the participation of stakeholders can be improved, the other stakeholders instead of government sector and Subak / P3A which is not included in the study need to observe. To increase the participation of Subak / P3A in the operation and maintenance of irrigation networks needs to be disseminated about the importance of stakeholder participation by the government so that the participation of Subak / P3A can be maximized.
