Runway is an airport facility which is very important for aircraft landing and taking off. The runway is a square area on the surface of the airport that is prepared for aircraft take off and landing, without a well-planned and managed runway, the aircraft will not be able to use the airport. In designing the runway, it is strictly regulated regarding the length, width, orientation (direction), configuration, slope / slope, and thickness of the runway pavement. This final project will analyze the feasibility of the runway length and the thickness of the pavement (runway) for the operational plan aircraft that will be used in the next 20 years. With ARFL corrections to the existing runway conditions, the current runway length is 2,500 meters. For the next 20 years traffic flow is forecasted using linear regression analysis from 2011 to 2037. From the forecasting results, it was found that the total aircraft movement was 19,138 movements (R1), so it was planned to use the B 737 900 ER aircraft because this aircraft had a passenger capacity of 220 seats. This aircraft is the reference for the planning of the runway dimensions. Some of the resulting planning analyzes include: the length of the planned runway is 2,498 meters long and 45 meters wide. Meanwhile, the pavement planning analysis resulted in a surface layer thickness of 4 inches, a base coarse layer of 13 inches, and a subbase thickness of 22 inches.

Keterbatasan data aliran merupakan kendala yang sering terjadi di dalam analisis ketersediaan air. Untuk mendapatkan data tersebut dewasa kini sudah banyak model-model prediksi debit aliran. Teknologi penginderaan jauh (remote sensing technology) dapat meningkatkan pengembangan studi model hubungan curah hujan–limpasan secara konvensional. Dengan teknologi ini dapat membantu dalam memprediksi debit limpasan untuk tiap Sub-DAS. DAS Unda merupakan salah satu DAS Potensial di Provinsi Bali. Analisis debit aliran ini dilakukan dengan metode overlay dengan mengoverlay peta tata guna lahan dan peta jenis tanah di DAS Unda sehingga mendapatkan nilai CN kemudian dilanjutkan dengan menghitung debit aliran prediksi menggunakan metode SSCN. Dari analisis dalam sepuluh tahun terakhir terjadi fluktuasi debit, dimana debit terbesar yang pernah terjadi adalah 10.569 m3/dtk pada tahun 2013 di subdas Telagawaja dan terendah sebesar 0,079 m3/dtk di subdas Tanah pada tahun 2010. Untuk subdas Telagawaja dalam sepuluh tahun terakhir debit rata-ratanya sebesar 8,068 m3/dtk, subdas Masin sebesar 0,963 m3/dtk, subdas Tanah sebesar 0,163 m3/dtk, subdas Nyuling sebesar 0,705 m3/dtk, subdas Kaun sebesar 1,653 m3/dtk, subdas Yeh Batah sebesar 0,564 m3/dtk, subdas Unda sebesar 1,722 m3/dtk, dan subdas Sangsang sebesar 0,764 m3/dtk

Performance assessment and preparation of AKNOP (operation and maintenance costs) were carried out on 13 reservoirs in the province of Bali, including Embung Badeg, Embung Batudawa, Embung Baturinggit, Embung Besakih, Embung Bukit, Embung Datah I, Embung Datah II, Embung Dukuh, Embung Muntig, Embung Seraya Timur, Embung Seraya, Embung Telung Buana, and Embung Untalan located in Karangasem Regency. The purpose of this study is to evaluate the reservoir performance against the specified assessment aspects and to obtain the planned operating and maintenance costs for the reservoir facilities and infrastructure based on the damage criteria. The evaluation of the operation performance and maintenance of the reservoir refers to the Circular Letter of the General Director of Water Resources, Ministry of Public Works and Housing. Meanwhile, the AKNOP value is calculated from the total of multiplication volume, frequency, and unit price of work for each reservoir operation and maintenance activity. The reservoir performance evaluation is based on four criteria, physical performance, operating and service performance, security and environmental system performance, and institutional performance. From the study, the result shows that 13 reservoirs' performances are in adequate condition. The operation and maintenance can be done by routine and periodic maintenance activities based on operating and maintenance cost plans. This activity is expected to reduce reservoir damage.

COMPARATIVE ANALYSIS OF WATERSHED CHARACTERISTICS IN BALI PROVINCE FOR SUSTAINABLE WATER RESOURCES MANAGEMENT I Gusti Agung Putu Eryani; Abd Muluk Abd Manan; Made Widya Jayantari

Aims: This research will provide an overview of the comparative analysis of watershed characteristics in Bali which are differentiated from watersheds flowing to the north, and watersheds flowing to the south of Bali Province. The aim is to determine the characteristics of each, and proper sustainable management for each watershed. Methodology and Results: This is a descriptive, quantitative research that analyzes and compares the characteristics of the Saba watershed and Unda watershed, where the characteristics analyzed are morphometric and hydrological. From the analysis, it was observed that the Unda watershed, which has a flow direction to the south of the island of Bali, and the Saba watershed, flowing to the north of the island of Bali, possess several differences and similarities. The similarities include rainfall patterns, high temperatures, and the comparison values between Qmax and Qmin is significant. Meanwhile, the differences include the Saba watershed slope being steeper than the Unda watershed, and the Saba has young geomorphic features, while the Unda watershed possesses advanced geomorphic features. Conclusion, significance, and impact of study: Differences in watershed characteristics lead to differences in the management carried out. Furthermore, in terms of hydrology, where there are lesser differences, the sustainable management of the Saba and Unda Watershed also require conservation in form of a reservoir (weir or dam). This is to enable the storage of water in the rainy period for the dry season.

The construction of the Wolowaru Community Health Center in Ende Regency has been delayed. Delays in the duration of this project will have an impact on project costs which will get bigger. Therefore, an analysis of the accelerated duration of project implementation is needed so that the initial target can be achieved. This study applies the crashing method, namely speeding up the duration of each work item according to needs and calculations so as to avoid excessive delays. The application of this method is assisted by using the Microsoft Project 2013 with alternative working hours or overtime and work shift systems. The results of the analysis on the Wolowaru Community Health Center construction project in Ende Regency showed that the total project cost after carrying out an alternative of two hours of additional working hours was Rp. 8,371,332,720 and the duration of project implementation is 175 working days. This shows a fee that is 0.62% more expensive than the normal total cost and 20% faster than the normal duration. Then for the project cost after carrying out an alternative system of morning shifts and night shifts, it is Rp. 8,359,287,673 and the duration of project implementation is 156 working days. This shows a fee that is 0.48% more expensive than the normal total cost and 39% faster than the normal duration. From this study, it shows that the implementation of the work shift system requires cheaper costs with a shorter duration of work than the implementation of additional working hours in the Wolowaru Health Center development project in Ende Regency.

The success of construction projects, especially in the construction of multi-storey buildings is influenced by material components. Therefore, optimizing material planning is important to do. In the Pacto Sanur Building construction project, optimization of material planning is viewed from the ironing work because it costs a relatively large amount compared to other works. The purpose of this study is to analyze the comparison of bar bending schedules on projects using the British Standard 8666:2005 and SNI-2847:2013 methods, then to identify project cost comparisons. From the results of the identification of iron planning using the SNI-2847:2013 method, it can be seen that the weight of Ø16 iron = 3971.00 kg, the weight of Ø13 iron = 251.51 kg, and the weight of Ø10 iron = 7034.38 kg. Furthermore, in the identification of repair plans using the British Standard 8666:2005 method, it can be seen that the weight of iron Ø16 = 42153.22 kg, the weight of iron Ø13 = 280.95 kg, and the weight of iron Ø10 = 7343.58 kg. The volume optimization for Sloof, Beams, Columns, and Floor Plates II uses the British Standard 8666: 2005 method of 47% with the total cost of the SNI-2847:2013 method ironwork Rp. 202,623,928 and the total cost of repair work using the British Standard 8666:2005 method is Rp. 213,799,435.
