It is known that the development of physical medium especially housingproblem is needed by everybody and has already developed by the developerseither in town or outside town. The houses vary started from their types, technicalspecification designs which are intended to be reachable by the customer.Eventhough the amenities offered by the developer such as paying installments, inreality there are still public civil servants (PNS) and private sector officers are notyet able to buy / to own a house by themselves caused by many reasons.In this research the selection of respondent was conducted using purposivesampling method. It is a research that base on the ability, knowledge and also certain consideration in selecting the respondents who are believed can make theirchoices and are able to answer the questioner promptly according to the relatedtopic. The analyses were carried out using the theory of linear probability modelmethod (LPM) and if the probable value is outside the definition (0 and 1) hence itwill be overcame by using a logistic regression model.The analysis results showed that the sum of the family members have a signifanteffect to the ownership of the house with a significant level of 5%. The coefficientof logistic regression was equal to 1.2142105 meaning that if family membersincrease one more hence the probability of the ownership of the house will increaseby 0.771043 (77.10 %). The value -2log likelihood equal to 27.953 was bigger thanthat of X2 table (7.815). This means that simultaneously the three independentvariables (earnings, work, and total of family member) have an effect towarddependent variable (ownership of house).

Although it has a large amount water resources but the agricultural land of Unda Irrigation Area still has water crisis. 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.

Abstract :Reducing the negative effect of erosion problem efforts either by hard structure (e.g. groin construction) or soft structure (e.g. Sand nourishment) solution have been already implemented. One of the location with sand nourishment solution as well as the groin construction is located in Sanur beach, Bali. This location is in critical situation, where the infrastructure is threatened by the lack of the sediment amount and hence it will be impact on the tourism. The evaluation of the coast line changing impact due to the existing of coastal structure need to be assessed. In the worst case, where the coastline changes significantly, the efforts to solve the erosion problems are by groin shape modification and adding the new coastal structure. Simulation results show that there are three segment of the coastal area in between the groin need to be overcome, GN.4 – G7, G39 – GA2 and G32 – G37. The methodology in this study is by comparing the simulation result with the measurement data in 2012. The evolution of coastline changing in those areas shows significant coastal recesion compare to the other places. What can be done to solve the problem is that by modifying and construct new structure. In GN.4 – G.7, we can construct breakwater paralel to the coastline in the middle. In GN 4, transforming the groin shape from T to I, in the location of G39 – GA2 we propose to omit the bending of the groin in GA2 and construct the groin parallel to the beach in between G39-GA2, in the location of G32 - G37 the breakwaters need to be constructed in the right side and in the left side of the groin G32. The modification of groin construction in the GN.4 – G7, G39 – GA2, and G32 – G37 reduces the losing of material. The coastal recession can be reduced from 6.15 m to 5.34 m in GN.4, in GA 2 from 3.4 m to 2.85 m, and in G32 from 3.69 m to 2.98 m.

Abstract : Tukad Penet is one of the biggest rivers in Bali which is used to support farming and fresh water demand. The increasing of water demand in various sectors such as for irrigation and drink water recently using water from Yeh Penet source shows the over use of its water has caused some conflicts between the use of the water user for irrigation and another use. Therefore, it was needed to review the use of Yeh Penet water to see how big the potential of its water that could be exploited to support the water source demand. The optimal analysis of water usage was carried out in six regional irrigation (DI) used Penet river water such as DI Peneng, DI Kacangan, DI Luwuscarang Sari, DI Penarungan, DI Kapal and DI Munggu. This analysis was based on cropping, planting and water management as well as a maximum water raw demand of the regional company of drinking water (PDAM) in Tabanan and Badung regency. Based on the simulation result, water availability in each irrigation regional (DI) depended on the cropping and planting. It was needed to provide the planting and rotation system for some irrigation regionals in river fluctuation discharge. The deficit of irrigation water balance occurred in DI Peneng, DI Luwuscarang sari, and DI Kacangan. The optimal use of irrigation water in the third irrigation regional was carried out by using planting stimulation and water management. The water balance analysis result at watershed in the part of downstream Penet watershed showed the availability of water surplus occurred in alternative plan I and II. The water balance analysis showed water availability in alternative plan I of a minimum 0.04 million m3 and maximum 1.43 million m3, whereas in alternative plan II the wasted water availability of a maximum 0.25 million m3 and a maximum 1.51 million m3. The potential development of Penet watershed in alternative plan I was 0.67 million m3 (0.52 m3/sec) and in alternative plan II was 0.76 million m3 (0.58 m3/sec) was not able to support the total water demand in Badung and Tabanan regency. Besides, the water source development of Penet watershed only occurred in downstream part of Yeh Penet river to avoid some conflicts of water utilization in Penet watershed.
