By Pass Ngurah Rai is the only primary arterial road linking the traffic flow of people and goods from Ngurah Rai Airport to Nusa Dua. Peak hour traffic flow condition has exceeded the capacity of the road. To solve the above problems, it is planned to build toll roads Benoa-Bandara-Nusa Dua. The objectives of this study were to analyze the performance of existing roads with and without the toll road, the rates applicable to service users and to analyze the financial feasibility of the investment of the project. Analysis was performed for several scenarios, including the scenario-1, assuming traffic growth factor of i = 9.96% / year, the interest rate 16% / year, inflation accounted for 8.506% / year and the toll rates using rates set by the Jasa Marga. All of the cost including land acquisition and construction costs were provided by investors. It was found that for the scenario-1, the NPV is Rp 1,586,137,984,347, -, BCR: 0.4754 and IRR 3, 8676%. The results of the financial analysis indicated that investment of the toll roads Benoa-Bandara-Nusa Dua is not financially feasible. In order for this project to be financially feasible, the growth rate of vehicles should be at least i = 14.7% / year.

Facilities in an airport requires maintenance activity in order to achieve excellent quality level and able to support activities at the airport to avoid negative impacts, which is the declining quality of the facility that can lead to lower levels of the productivity carried out in an airport. Maintenance facilities at Bali's Ngurah Rai airport need the maintenance costs planning. To get proper maintenance actions, the maintenance costs early stages of planning phase needs to develop a model of facility maintenance costs that can provide the maintenance costs estimates quickly and accurately. To produce a maintenance costs model we should identify the maintenance activities that exist at Ngurah Rai airport. Maintenance costs data used is within the last 5 years (2007-2011). Using the Cost Significant Model methode and the linear regression equation it showed that several of the facility maintenace significantly affect the facility maintenance costs in the Ngurah Rai Airport which is the cost of passenger terminal building maintenance (X6), the cost of runway maintenance (X1), the cost of taxiway maintenance (X2), the cost of air conditioning installation maintenance (X14), the cost of road maintenance (X4), the cost of vehicle parking maintenance (X5), and the cost of navigation and communication equipment maintenance (X10). There is 3 linear regression equation model which is 1) Y = 11873745878,77 + 0,993 X1 + 0,826 X2 + 0,334 X4 + 1,181 X6, 2) Y = -698840481,94 + 1,327 X1 + 1,716 X2 + 5,516 X5+ 3,060 X14, and 3) Y = 82110363478,07 + 1,013 X1 - 17,223X5 + 22,406 X10 - 12,035 X14. After doing the Cost Model Factor (CMF) test to the three linear regression equation, the most accurate equation is linear regression equation Y = 82110363478,07 + 1,013 X1 - 17,223X5 + 22,406 X10 - 12,035 X14 that has the average ratio 0.006% of the actual cost, so it is the best facility maintenance cost model at Bali's Ngurah Rai Airport.

The garbage transportation in Bangli City is currently done using a direct individual pattern (door to door). The vehicles used are dump trucks which are not covered, so they pollute the areas they pass by. Most of the vehicles are in bad condition. This study was aimed at identifying the transportation routes, the number of vehicles needed, the temporary place of garbage disposal ‘Tempat Pembuangan Sementara’ (TPS), and the rate of garbage retribution. The research method included the sample of garbage from the place of residence and the place of non residence based on SNI-19-3964-1994 used as a reference. This model used five compactor trucks for carrying garbage from 283 container bins with capacity of 0.36 m3, and one armroll truck for carrying the market garbage from four loudhaul with capacity of 6 m3 per day. The amount of retribution is analyzed based on the calculation of investment feasibility for 10 years time at 18% MARR interest rate, with an assumption that there was subsidy from the government. It was found that the value of NPV (Net Present Value) was Rp. 35.673.540,99, the value of BCR (Benefit of Cost Ratio) was 1.021 and the value of IRR (Internal Rate of Return) was 19.11%. The monthly rates of retribution were Rp. 2,000.00/family, Rp. 20,000.00/school unit, Rp. 25,000.00/office unit, Rp. 8,000.00/shop unit, Rp. 20.000.00/restaurant unit, Rp. 2,000.00/hotel/accommodation unit, and Rp. 6,000.00/market trader.
