Abstract

Traffic congestion in the city of Semarang is increasing. This is due to the unbalance between the development of road infrastructure and the increasing number of vehicles. Therefore, an orderly, smooth, safe, and convenient mass transportation is needed to reduce congestion. The purpose of this research is to analyze the performance of Bus Rapid Transit (BRT) operation in Semarang City through Kaligawe road. This route is expected to become a reliable public transport in breaking down congestion. The research methodology begins with conducting a Kaligawe road performance survey which is about 4 KM in length, including traffic volume of Semarang-Demak direction of 3.982 emp and the reverse direction of Demak-Semarang is 3.814 emp. While degree of saturation ranged from 0.59 to 0.83. The results of the analysis on BRT found an unbalanced comparison between the capacity of BRT and the volume of traffic passing through the road. The results of this analysis and survey is necessary to maximize the function and work of BRT in several ways ie the location around the shelter must be barrier-free so that BRT can stop at the shelter. there should be a shelter guard who serves as a janitor, security, and information provider about the schedule and about the BRT. The socialization needs to be improved to the public, preferably the holding of Smart Card and feeder transportation, and the holding of tariff reduction in order to increase public interest.

Abstract

Cost estimation is an important element in the overall cost management project, It is used to plan and control the resources, such as materials, labor, and equipment. In this case, the construction management has function to ensure the implementation of the construction project properly in order to achieve the goals of the project. Project planning urgently needs a precise and accurate method in analyzing the allocation of the proportion cost of the resources planned. It must be implemented in the beginning before start of the construction, therefore it is necessary to conduct a detail study of the factors related to the financial of the composition of resources such as labor, materials, and tools. Previous researches on cost allocation of construction project resources were carried out; Hermiati, Zahraie, B. and Tavakolan, M., Lin, K., Heon Jun, D. and El-Rayes. K. Hermiati. (2007) conducted a study about Modeling and Analysis of the wages of labor in the construction projects with the research objects of infrastructure development projects (building). Zahraie, B. and Tavakolan, M. (2009) examined the Stochastic Time-Cost-Resource Utilization Optimization (TCRO) Using Nondominated Sorting Genetic Algorithm and Discrete Fuzzy Sets). Lin, K. (2011) has conducted research on Human Resource Allocation for Remote Project Construction. Heon Jun, D. and El-Rayes, K. (2011) conducted research on Multi-objective Optimization of Resource Leveling and Allocation during Construction Scheduling. Previous researches on resource variable of project construction carried out by Muzayanah, et al. Muzayanah, et al (2008) modeled the proportion of project construction resources. The conclusion was in the form of a mathematical model of the proportion of project resources, and the average use of construction project resources. The conclusion was mathematical proportion of project resources and the average of construction project resources in a simple building compared to non-simple building. The conclusion of the first year study was project construction cost that has four variables; Wibowo, et al (2014), consisted of the cost variable of human resources, building material, equipment, and others cost. The final conclusion of this study (Wibowo, et al, 2015) resulted in a statistical/ mathematical model and conceptual framework model of the decision making system on the cost allocation of construction project. Statistical/ Mathematical Model of Cost Allocation on Project Construction in general "Yn = Pn + Qn + Rn + Sn", which Yn shows the variable of Construction Costs. P Variable indicates the variable cost of Human Resources, Q shows Variable Cost of Building Materials, R shows the variable cost of equipment, and S indicates Other Costs Variable. Each of these variables is the model formula of Other Costs. The formulation of the model variables P, Q, R, and S depends on the value of Y.

Abstract

The demand of wood as construction material always increases. However, sawn-wood with large size is more difficult to find in the market due to decreasing in stock dimension. In addition, it makes price more expensive. Indonesia has many trees from fast-growing species: however, they have low wood quality, and still limited in usage. To obtain a better performance of fast-growing species as construction material, it needs to be combined to produce glulam. This research observed the influence of position and longitudinal connections of wood glulam beam on strength and stiffness with damage species of sengonglulam beams. Preliminary testing was done to obtain physical and mechanical properties of clear specimen of sengon wood, testing method followed ISO-1995 standard. Fifteen glulam beam specimens whichhad 70 mm wide, 200 mm depth, 3000 mm length were constructed: They represented variations of position and connection work of 0 %, 25 %, 50 %, 75 % and 100 %. Each layer of lumber glued with thermosetting phenol formaldehyde (PA-302) adhesive at pressure 1 up to 1,1MPa for 10 hour pressing time. The static lateral loading steps were done continuously until the beam was damaged. The result indicated that sengonwas V class of strength. Glulam testing showed that in terms of strength and stiffness, the higher the number of connections, the lower the value. The strength reduction percentages of 0%, 25%, 50%, 75% and 100% produced 0%, 13,08%. 28,11%. 29,42%. 70,72 %. Respectively and the degradation of glulam stiffness were 100%. 99,92%. 87,86%. 83,06%. 67,08%. The failure of glulam beam with 0% had a shear followed by flexure damages of 25%, 50%, 75% and 100%. A flexure damage was followed by shear damage. Keywords: Paraserianthesfalcataria, Connection, Glulam Beam, Strength, Stiffness.

Abstract

Sanitation and waste water become an important issue, as population growth. It is estimated that in the next 2025, almost 68.3% of Indonesians inhabit urban areas. Population access to the basic infrastructure of settlements is influenced by aspects of health, environment, socio-cultural education and poverty. Community-Based Environmental Sanitation (SLBM) is one of the sub areas of DAK in the Infrastructure Sector, sourced from the State Budget (APBN) provided to finance sanitation and wastewater activities in regional affairs and become a national priority. Through this research to get: 1) evaluation of program policy toward implementation performance of SLBM, 2) factors influencing performance of SLBM program implementation, 3) dominant factor influencing to SLBM implementation. The research used qualitative quantitative method of quantitative with multiple linear regression analysis. Regression model formed Y = 0.966 + 0.093 X1 + 0.207 X2 + 0.190 X3 + 0.191 X4 + 0.097 X5, where the value of F arithmetic is 36.159 with a significance level of 0.000. The significance level obtained is 0.000 <0.05 so that the regression model is considered feasible to predict the dependent variable (Y) based on the independent variables. Of the five variables tested, community assistance with the coefficient of determination is 32.9% is the dominant variable that affects the success of program implementation performance. The aspect of participation is so important to support the success rate in the development and development of sanitation, therefore the cooperation of all parties between the government and the Sanitation Working Group, the community and all parties is expected to be sustainable.

Abstract

It can be denied that most of roads condition in Indonesia is worst. It is because maintenance works is not properly conducted because of insufficiently, unsustainably, and inconsistency on allocating budget for maintenance. Insufficient or uncertain budgetary allocations to road maintenance have resulted in road deterioration that has significantly increased production and transport costs. To avoid this problem, highway professionals advocate the establishment of dedicated road funds, managed by independent road boards made up of road user representatives. So far roads maintenance in Indonesia is financed using the government budget allocation. It is difficult to give guarantee to the sustainable road maintenance if the finance for road maintenance takes from the government budget allocation. Therefore in this paper will be introduced road fund, the road maintenance funding system widely used in some countries that road conditions can be well maintained. The conclusion isthat the road fund needs to be applied to maintenancethe road in Indonesia.Keywords: Road, deteriorate, maintenance, road fund, budget system, sustainable
