Abstract

Some research on the Ultrasonic Pulse Velocity (UPV) test has not covered much about the problems encountered during the data collection process. Based on experience using UPV test equipment, it is known that instability occurs in reading the test results. This is caused by the inability of the operator, in maintaining the stability of the transducer both in its position and pressure, especially in the measurement with the overhead position. Therefore, in this study a tool was made to make the transducer stable in the test position. Comparison of measurement results shows that, the uncertainty of wave velocity measurement decreases from the range of 4% -17% to 0.2% -0.4%. Meanwhile, the uncertainty of measurement of wave travel time decreased from the range of 0.8% -14% to 0.1% -0.4%. This can be interpreted that, the level of accuracy of measurements using a transducer stabilizer is 99.6% -99.9%. Thus, the use of transducer stabilizers is believed to be able to improve measurement accuracy.

Abstract

Darul Hikmah Mosque is a building located inside Politeknik Negeri Semarang as a place of worship for all campus residents, and people who live around the area. The prayer activity is preceded by the Wudu. In order for Wudu to be carried out perfectly, sufficient quantities of water are needed. The lack of pressure and discharge of Wudu tap water, when used simultaneously, becomes a constraint that is the water pressure decreases. The purpose of this study is to determine the factors causing the lack of water discharge or pressure as required in SNI 03-7065-2005. The research method is quantitative descriptive by evaluating the performance of the existing water supply system and using a discrepancy model by comparing the evaluation results with existing data to find discrepancies. Evaluation results indicate that the factors that cause the lack of water pressure are the roof tank height is less than ideal for water distribution with gravitational power, and the volume of available water is not sufficient

Abstract

Flood is a disaster that has the biggest threat, in terms of the number of victims or losses. Semarang City is a city that is classified as a flood prone area, this is due to the geographical location in the lowlands and highlands. The impact of the flood disaster caused damage and losses from various sectors of public infrastructure including the education service sector and health services. Damage and loss of public infrastructure will burden the government in the post-flood recovery phase. An assessment of infrastructure damage and losses from flooding is needed in order to help the Semarang City Government prepare a budget plan and manage rehabilitation and reconstruction. The purpose of this research is to explore the loss of public infrastructure due to the impact of the flood disaster, so that it can accelerate the post-disaster recovery process and management strategies for the risk of further flood disasters. The valuation method used is ECLAC (Economic Commission for Latin American and the Caribbean) Method. This method can identify damage and estimate the losses caused by floods. The results of this study are that each public infrastructure building has a different level of damage and loss and the budget allocation for disaster management each year is still inadequate. A risk transfer strategy is needed with an insurance financing scheme based on the level of risk in each infrastructure building.

Abstract

The Government of Jakarta is trying to reduce the traffic volume by launching many new rail-based public transportation modes in this Jakarta Capital Region, one of them is Jakarta LRT. There are so many special things at the LRT Velodrome Station, for example the strategic location of Velodrome, the Jakarta International Velodrome stadium, integrated with Transjakarta transportation mode, etc. Even though the Jakarta LRT is the new transportation mode, but the Jakarta LRT only used by few people, because the route is still too short only 5,6 km (Pengangsaan Dua to Velodrome). So, this research discuss about the preference of passengers in using Jakarta LRT as the option for their daily transportation. The analysis of data obtained in this research by using the “Importance Performance Analysis” method, and analyzed the validity and reliability by using SPSS 24 program. The results of people’s preferences by using Jakarta LRT in this research are located in quadrant II that have a good performance on passengers satisfaction, so the performance must be maintained. And the items that needs to be improved for the efficiency and effectiveness are located in quadrant I that requires the high priority on its performance

Abstract

The world of industrial construction is always developing, thus there are negative impacts arise such as the reduction of free / green land, the use of construction materials originated from natural resources in very large quantities, excessive use of energy, and air pollution. We can actually use the tropical climate in buildings and the environments using the green building concept. The green building concept includes several parts of the construction process such as green initiation (awareness of the green building concept), green design (green building design), green construction (environmentally friendly construction process), green operation & maintenance (green building maintenance). This research is conducted with the aim of analyzing the effectiveness of the application of the green building concept in construction of the buildings. The method used in this study is to compare the total cost of maintenance and impact between buildings categorized as buildings with conventional concepts and buildings with green building concepts. The variables used in this study to include the use of the type of material, monthly electricity costs, and monthly water costs. In processing the data the writer use EDGE software and the results of data processing will show the difference in the total maintenance costs of the two buildings.

Abstract

Based on the initial plan from the contract of the Rehabilitation Klambu Kiri’s Project, main channel's work was carried out continously by an open and closed system using the kistdam method. However by the time of execution work, the stakeholders wanted the work in the main channel to be carried out based on cropping pattern, where there a drying period and a drainage period. In this case, flow area and bottom structure of the channel can only be worked during the drying period lasting three months. To be able to determine the impact of these change, a duration calculation is carried out from project's data which are internal's BQ, initial plan's resources, and the relations between activities using Microsoft Project on the flow section structure which be worked in drying period of 2017. The normal duration obtained from analysis is 203 days. It was exceeded time of drying period and possibly could have an impact on the overall project completion schedule resulting in delays, defaults and even termination of contracts. Therefore, it is necessary to have an accelerate strategy of the work on the flow section structure to be completed within a predetermined time. In this study, the acceleration strategy was carried out using crashing analysis in the critical activities from normal duration using Microsoft Project. The crashing method was carried out in stages from the crashing simulation of 30 days, 60 days, to 120 days so that obtained the duration of acceleration was 83 days. The cost component of acceleration is calculated by choosing the lowest cost from the alternatives of increasing work hours (overtime) or by adding resources. From the simulation results, the crash cost to complete the acceleration work is Rp. 1.298.307.591,- or about 2,05% of direct cost, so the efficiency is Rp. 9.692.409,- from normal duration

Abstract

The main issue in the utilization of ground water is always related to the decrease in water table or piezometric level. The decreasing of groundwater level is often accompanied by number of environmental impacts such as; subsidence, sea water intrusion, or reduced water from residents' wells and surface water bodies. Therefore, an experimental and numerical study was carried out to learn phenomena of cone depression resulted by groundwater production well. The experimental study of physical modeling used the S12-MKII Hydrology Study System equipment, and numerical modeling used Groundwater Modeling Software - Modflow. The modeling results were verified by analytical estimation. The results indicated that the groundwater withdrawn obtained with physical model and numerical simulation is bigger than estimated by analytical equation, particularly in estimating groundwater divide to a well.
