Abstract

Traffic volume in Semarang City has increased every year due to the increasing number of vehicles. Congestion that occurs at the T-junction intersection Jl. Brigjen Sudiarto - Jl. Majapahit is one of the impacts of high traffic growth and the traffic system is not functioning properly. By considering the geometric conditions of the road, traffic volume, side obstacles and the intersection environment which is a commercial area, it is necessary to analyze the cause of the congestion at the intersection. The research conducted was to conduct a field survey to obtain primary and secondary data which are then processed using intersection management. Planning uses the 1997 Indonesian Road Capacity Manual (MKJI) and uses the Excel 2013 program to process traffic data. Traffic data is obtained from recording the number of vehicles in the field for 3 days (April 29, 01 and May 4, 2019) during peak hours and presented in the form of a vehicle data table, then the behavior of the intersection can be analyzed. From the analysis results obtained value of the degree of saturation (DS) at the intersection of Jl. Brigjen Sudiarto - Jl. Majapahit 0.991. This value has exceeded the required value by the 1997 MKJI, DS ≤ 0.85. The analysis shows that the average traffic delay is 141,320 sec / pcu, so this intersection has a Service Level (LOS) F (> 60).

Abstract

Artificial Neural Network (ANN) is a Machine Learning (ML) algorithm which learn by itself and organize its thinking to solve problems. Although the learning process involves many hidden layers (Deep Learning) this algorithm still has weaknesses when faced with high noise data. Concrete mixture design data has a high enough noise caused by many unidentified / measurable aspects such as planning, design, manufacture of test specimens, maintenance, testing, diversity of physical and chemical properties, mixed formulas, mixed design errors, environmental conditions, and testing process. Information needs about the compressive strength of early age concrete (under 28 days) are often needed while the construction process is still ongoing. ANN has been tried to predict the compressive strength of concrete, but the results are less than optimal. This study aims to improve the ANN prediction model using an H2O’s Deep Learning based on a multi-layer feedforward artificial neural network that is trained with stochastic gradient descent using backpropagation. The H2O’s Deep Learning best model is achieved by 2 hidden layers- 50 hidden neurons and ReLU activation function with a RMSE value of 6,801. This Machine Learning model can be used as an alternative/ substitute for conventional mix designs, which are environmentally friendly, economical, and accurate. Future work with regard to the concrete industry, this model can be applied to create an intelligent Batching and Mixing Plants.

Abstract

Water is a major and important resource in the process of life in the world because of every living creature whether human, animal, and plant needs water. The technology of artificial geomembrane reservoir or water tank is the small reservoir in the village land (TKD) which is built to collect the water in the rainy season by using waterproof material as the layer by utilizing the rainwater through the river around which is then used as an alternative source of clean water (water supply) in the dry season. As for the calculation methods used for this research include: analysis of rainfall area using algebra average method (arithmetic mean), the calculation of rainfall plan can be done by using disperse measurement, with the statistical parameter of the calculation result of Sd= 23.884 Cs= 1.933 Ck= 4.031 Cv= 0.233. The distribution analysis is done using the Gumbel 1 method for 10 years plan amounted to 146.601 mm/day. Rainfall intensity analysis is done by using the Mononobe method for 10 years rainfall intensity plan amounted to 6.108 mm/hour. For the next 10 years, population projection is done using a calculation of the Arithmetic method of 2.795 populations. The conclusion of this research indicates that the clean water need in the dry season at Tanggung Prigel Village, Glagah District in 2026 is approximately 0.001941 m3/sec. While the plan for reservoir debit of 0.003254 m3/sec so it is considered sufficient to fulfill the clean water need in the Tanggung Prigel Village, Glagah District.

Abstract

Indonesia as the second largest contributor in global were produced about 9.52 million tons plastic or 14% of the total waste. The rapid population growth of urban area in Indonesia indirectly encourages various activities that affect the volume of waste. Semarang city were contributing waste in landfills reaches 850,000 tons per day, where 1,000 tons unmanageable. Unsorted garbage has the potential as new materials option in cultural heritage buildings. To elaborate these potential options, this research has been conducted qualitative method as the best approach to answer the research question. This research investigates the stakeholders’ perspectives about potential of plastic waste for replacement material of heritage buildings. The results show that there is a lack of data on waste management which is one of the challenges to find out how much volume of plastic waste can be reused. In addition, the principle of building cultural heritage is opposed to the use of plastic waste as an alternative material as a substitute element. In conclusion, plastic waste has a little potential from current waste to be applied on heritage buildings are limited element such as roof, furniture or temporary support of the structural element.

Abstract

Two generally method / tools which used in project construction management system in Indonesia and the name are CPM (critical part method) or network planning and Bar Chart. The system used general method called conventional management system. Nowadays, was appeared one of a new system which seldom to applied in Indonesia, it is called LPS (last planner system). This research, researcher doing analyzed the differences between LPS and conventional management system. The result which obtained in this research are LPS dominated to accentuates team collaborative in the scheduling planning, resource allocation, control and enhance of work productivity, issue solved, regularly scheduling planning. Conventional management system more rely on the way CPM and Bar Chart working in that system with project manager decision. Planning of the schedule in this system doing by scheduling team. rescheduling in this system is not routine, it’s depend by construction progress. CPM and Bar Chart methods is influence on LPS. The both of methods was appeared in master scheduling, look a head scheduling, weekly work planning, shielding production, workable back log, percent plan completed and reliable promise process
