Abstract
Underpass Jatingaleh is designed to solve congestion problem and reduce the rates at which accidents occur at intersections due to conflicts, but bottleneck can affect traffic performance. This study aims to determine changes in traffic movements, traffic performance after the existence of Underpass based on MKJI 1997, analyze density with the Greenshield linear approach, and analyze the effect of bottleneck. To be more effective, the survey is conducted by using drones. Based on the analysis, the road performance becomes better, but some segments should be optimized because degree of saturation (DS) > 0.75. The vehicle speed results are 52.29; 55.49; 29.87; 26.28 Km / Hour in segment A; B; C; D and Segment Density C; D = 155.71; 152.86 pcu/Km. Vehicle speed on bottleneck Segments C and D, in Setia Budhi Street does not meet the Primary Arterial Road criteria at 60 km / hour with very high density result. Bottleneck causes increased density, raises new conflict points (weaving), decreases vehicle speed up to 42-46%, and causes queue length of 0,150 Km. We propose that the Underpass it must be in accordance with the geometric requirements of MKJI, there should be no narrowing of/ the road in any segment.

Abstract
Transparency and Accountability are two principles of good governance and need to be prioritized in applying the concept of good governance. Both of these principles have a close and mutually supportive relationship. Without transparency, there will be no accountability and without accountability, transparency means nothing. This study aims to discuss the relationship and position of these two principles through criteria and methods based on literature review. According to the Construction Services Act, the selection of service providers as referred to in Article 41 which uses funding sources from state finances is carried out through tendering or selection, electronic procurement, direct appointment, and direct procurement in accordance with statutory provisions. Electronic procurement as referred to in paragraph (1) is the method of selecting Service Providers listed in the catalog. Data collection is sourced from Indonesian legislation related to the procurement of Government goods / services. Equipped with 50 national and international articles that discuss transparency and accountability in the procurement of goods / services. However, from a number of articles that have been analyzed, few have specifically addressed infrastructure. The results of the study are presented in the form of a model of transparency and accountability in the infrastructure public sector.

Abstract
Urban communities have a tendency to have high movement activities. To carry out their daily activities, the community is assisted by a variety of transportation modes. Most people in Yogyakarta urban area use private vehicles, such as motorcycles. The excessive use of motorcycle certainly has negative impacts like traffic congestion and increases travel time and air pollution. Government policies are needed to reduce motorcycle ownership and promote the use of public transportation. The policies issued must be pushed and pulled, which means that the policies issued should be able to not only improve public transports but also suppress the ownership and movement of private vehicles. The purpose of this paper is to understand the factors that influence motorcycle ownership. First understand about travel characteristics, household characteristics, and travel movements. Sources of data were collected from the survey by conducting interviews with household interview surveys in Yogyakarta Province. Data collection was carried out at the end of 2015

Abstract
A static equivalent is an approach method to design earthquake loads that must be calculated in the structural design. This method is practical and easy to apply, but only appropriate for low structures with high rigidity. This paper aims to investigate how high structures are still allowed to be designed using static equivalent earthquake loads. Validation is done by comparing the results of the static equivalent analysis with the results of time history analysis representing the reality. The structural models are four open resisting concrete frame 2D, with 7, 9, 10 and 15 stories. The Analysis use the SAP2000 program resulting in a structural response, include a base shear, story shear, and displacement. The result of the analysis shows that the static equivalent method is not recommended to design earthquake loads of more than nine stories structures. The potential damage of structures designed using static equivalent methods is in the basic story.

Abstract
In Citarum River, West Java, Indonesia, there are three serial reservoirs successively spreading out from upstream to downstream, namely Saguling Reservoir with the volume of 875 million m3and electrical energy production of 700 MW, Cirata Reservoir with the volume of 2,156 million m3 and electrical energy production of 500 MW, and Jatiluhur Reservoir, the most downstream, with the volume of 2,451 million m3 and electrical energy production of 150 MW. Jatiluhur Reservoir also provides supply for irrigation of 260,000 ha areas and drinking water industry with average inflow of 100m3/s. Those reservoirs have highly fluctuated with maximum water level 5 m per month. This condition occurs as sharing-non-sharing system is applied. Although this fluctuation is still in a normal condition, it affects the stability of reservoir slope. This study discusses about the validation of linear method to reach an optimal value of reservoir production in terms of electrical energy. The primary reservoir inflow data used was from 1988-2000, while the demand data was taken from 1992-2000, Cascade reservoir technique data was based on the existing data in 2000, Stochastic analysis was used to determine the inflow of 2000-2005 generation, while demand analysis was carried out using regression analysis. Multi-reservoir optimization analysis is carried out with linear simulation programs to obtain energy or fulfillment of demand every month, while demand for irrigation in the Jatiluhur reservoir is needed as a top priority supported by Saguling, Cirata and Jatiluhur reservoirs as the next priority. The result of optimizing cascade reservoir from 2001-2005, with initial period of operation on April obtained an average electrical production of 4,996.5 GWh, shows that the realization of average electrical production is 4,141.96 GWh. Besides, the average of demand is 4,996.8 MCm while the average supply is 5,806.2 MCm.

Abstract
Most of the houses in Indonesia are still categorized as non-engineered buildings which do not use good structural analysis in the manufacturing process. The level of education and knowledge about the construction of simple houses is certainly the main cause. The geographical conditions of Indonesia which are quite prone to disasters such as earthquakes, eruptions and cause this condition is one of the real threats to the population of Indonesia. This study discusses the level of vulnerability of buildings in the Klaten area to earthquake hazards. This area is one of the areas affected by the earthquake in 2006, and the community living was rebuilt with funds from the Indonesian government. The results showed that at the time of the initial construction 95% of this building had been calculated to withstand earthquake loads, this was seen from the main building which had a fairly strong structural component and was equipped with a fairly good structural drawing. Along with the growth of the population, most of the buildings have undergone a change of shape, many people have added their own buildings without considering the strength of the construction to withstand earthquake loads. so that buildings that were initially categorized as resistant to earthquake forces are very dangerous if an earthquake occurs.

Abstract
The Central Java Province has many river watershed that are not known water quality, water class and its function. Babon Watershed is one of watershed where located at north slope of Ungaran Mounth. Babon Watershed consist of three rivers basin, i.e. Gung (8,372 Ha ), Pengkol (7,009 Ha), and Babon downstream (9,202 Ha). The main river is about 33,76 km length. Base on its function, from upstream to downstream of Babon Watershed can be divided into 8 segments. The research aims to measure water quality and water class, to know each function and to predict its pollutant load capacity. Data collecting method use sampling for each segment. Meanwhile, the parameters measured are Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Dissolved Oxygen (DO), Natrium (Na), dan Phosphat (PO4). There are 17 sampling locations that consist of 9 location points in the main river, 5 points in the tributary, and 3 points random withdrawal. Data analysis was carried out based on Government Regulation No.82 of 2001. According to the analysis results obtained that in segment number I, II, III of Babon Watershed is recommended to function in class II, while segments number IV, V, VI, VII, VIII are recommended to function in class III, for 2.17 m3/s flow-rate can be COD 50 mg/l.

Abstract
Pekalongan River has two functions for fishing boat transportation and also the main drainage of Pekalongan City. The Pekalongan river estuary has Jetty located on two sides of the river mouth. The jetty used to protect to wave and sediment. The Pekalongan river had upstreams flow from Kupang and Banger river. Because of the flood incident around 2003, Since 2014, the two river became one estuary. This condition has a negative impact of sediment at the river mouth. So that the research aims to find solutions by simulating waves, currents and sediments. In this paper the focus is about the wave simulation. This research method begins with the collection of primary data in the form of bathymetry measurements at the river mouth. While the secondary data is wind data for 13 years and tidal. Calculations generated from wave forecasting are the results of a significant high value of 1.38 m and a significant period of 4.80 seconds. For wave simulations, SMS software is used with the CGWave module. Based on the results of the simulation, the wave propagation movement results when the dominant wave direction comes from the northwest, north and east. The simulation results can be used to analyze the movement of sediment transport that is affected by the movement of waves around the river mouth.
