Abstract

At the time of the high intensity of rainfall in Semarang, the water contained in the Babon River had overflowed, resulting in flooding of parts of the area adjacent to the Babon river flow. This matter has many factors, there are erosion and sediment produced. This study aims to study erosion potential in the Babon watershed, using the Geospatial Interface for Water Erosion Prediction Project (GeoWEPP) modeling. The results of the modeling are the amount of erosion rate and erosion distribution in the study area. The erosion prediction period in this study is in 2006 - 2015. Data needed in GeoWEPP operation are Digital Elevation Model, climate data, land use data, and soil type data. Based on the GeoWEPP process in the Babon watershed the erosion rate was 36.1 tons / ha / year and the sediment yield was 26075.2 tons / year. From the results of the erosion rate produced divided by the reasonable erosion rate get the Erosion Hazard Level index (TBE) of 3.6 or including medium TBE. Based on the distribution of erosion maps produced, the area experienced the greatest erosion rate in the Ungaran region. This is due to the fact that it belongs to the highlands and has a high slope value.

Abstract

The development of transportation occurs along with the development of residents in an area. The impact caused a buildup of vehicles on the highway. Transportation growth is linearly related to the Traffic Light Signaling Tool (APILL). Giving a Traffic Giver Tool is one way to regulate traffic. The methods that can be used for the duration of the APILL include the 1997 Indonesian Road Capacity Manual Method and Webster. The location of the study was in the Simpang Statue area of Pangeran Diponegoro and Abdulrahman Saleh. The webster method is calculated based on vehicles that come randomly. The calculation of the webster method is used to calculate the average delay of a vehicle when approaching an intersection where this delay occurs due to the large number of vehicles entering compared to the vehicle coming out of the intersection. the use of this webser method aims to be able to produce the optimum cycle time at each intersection. The Indonesian Road Capacity Manual Method (MKJI 1997) is a manual for road traffic calculations but cannot be used to analyze networks. This intersection obtains a degree of saturation average of ≥ 0.75, meaning that this intersection experiences a buildup of vehicles or congestion. The capacity and volume of vehicles in each intersection are inversely proportional. The intersection capacity can only accommodate around 2500 vehicles / hour but when on the field there are 7200 vehicles / hour. This makes APILL not work in each intersection. Simpang Statue of Pangeran Diponegoro and Abdulrahman Saleh is included in the F service (low speed blocked flow). The duration of the APILL time is not the same every day because the vehicle volume changes in each hour so that it is designed several plan APILL in the intersection. To overcome this kind of incident can be assisted by officers from the Police or the Semarang City Transportation Agency. Until now the APILL method still uses the Indonesian Road Capacity Manual 1997. Compared to the Webster method, the data needed is very minimal or incomplete. The results of the APILL time duration obtained using the 1997 Indonesia Jalan Capacity Manual method differ from the duration of time in the field and generally the results of calculations the duration of time obtained from this method added 10% of the calculation results and applied in the field.

Abstract

At present, there are many damages to concrete structures in buildings that have build. One such damage is the appearance of cracks. Cracks in concrete are caused by many factors, including loads that exceed limits, temperature, components of the constituent material, the process of making concrete and time.This research was conducted with the aim of studying the effect of the use of admixture "x", fiber and cement grouting on the compressive strength and cracking of concrete in untreated concrete. The specimens in this study are in the form of a concrete slab with a size of 1 m × 1 m with a thickness of 6 cm, cylinder size Ø 15 cm with a height of 30 cm, concrete quality plan K 250 (20,75 MPa), viscocrete, fiber type monofilament polypropylene, and cement grouting.The results of this study indicate that the addition of fiber can minimize the appearance of cracks in concrete. In addition, it also increases the compressive strength of concrete, namely K 295 (24,5 MPa). The use of viscocrete actually causes the most cracks if not cured, but has the highest strength, namely K 340 (28,3 MPa).

Abstract

Concrete is a material used for buildings construction such as buildings tower, bridges, etc Concrete consists of a mixture of fine aggregate, coarse aggregate and water. The price of material is increasingly expensive because the material limitations are not comparable to needs.This study uses data collection techniques with interviews, documentation, literature studies and direct observation and sampling at the site. The research of type of sand, sludge content testing and compressive strength testing were carried out in the SOEGIJAPRANATA Faculty of Engineering Faculty of Engineering's Civil Engineering Study Program laboratory. The purpose of this study was to determine the compressive strength of concrete with low quality sand plus admixture "XY", knowing the exact dosage of "XY" admixture material so that the concrete with low quality sand had the same or more compressive strength for concrete using good quality sand.The conclusion of this study is that low quality sand concrete added with admixture "XY" produces a compressive strength of 10% greater than the compressive strength of concrete with good quality sand without using admixture "XY". However, the use of the "XY" admixture material is not recommended or depends on consumers who want to use because the price is not economical. Therefore it is necessary to conduct further research using other admixture materials to increase the compressive strength of the concrete with this low quality sand.

Abstract

Reinforcing steel is one of the major construction materials which produces significant CO2 emission. In addition, reinforcing steel is also the main material in various construction Project type. Type of construction project which uses large amounts of reinforcing steel is high-rise buildings. The growth of high-rise buildings almost all over the world tend to increase. The tendency can be shown in Indonesia which has a total of 621 high-rise buildings. With this amount, Indonesia is one of 10 countries which have a significant tendency in the growth of high-rise buildings. Furthermore, the large and small of CO2 emission of reinforcing steel is indicated sourced from the supply chain as well. Hereafter, the reinforcing steel on the site needs some heavy equipment such as bar bending, bar cutter and transportation using tower cranes. The contribution of CO2 emission from the supply chain and install on site becomes important as it contributes in shaping cycles within the construction project. The existence of such cycles can be shown by the source and the amount of CO2 emission produced by each step. By using LCA, the source and amount of CO2 emission from each step can be found. The scope developed in this research is cradle to install. The result of the research shows that the size of CO2 emission in the cradle section range from 99 kg.CO2/m3-171 kg.CO2/m3. Furthermore, the size of CO2 emission in the supply chain section ranges from 10 kg.CO2 / m3-21 kg.CO2/m3. The size of CO2 emission ranges between 1 kg.CO2/m3-5 kg.CO2/m3. The result of the research is that reinforcing steel cradle is the biggest source of CO2 emission. The CO2 emission on the site is the smallest compared to the cradle and supply chain, but they cannot be ignored because they also contribute to and make a big determinant of CO2 emission in the construction project.

Abstract

Industrial estates have a large scale workforce. Workers usually come from different locations, so they need transportation to get to the Industrial Estate location, because of the large movements of industrial workers. Especially at the turn of the morning and evening work shifts, at these hours the number of vehicle workers contributes to traffic congestion on the roads it passes. The survey was conducted at the entrance of the industrial area to determine the level of congestion that occurred at the entrance of the Industrial Zone road section, namely on the Kaligawe road, Jalan Candi Raya, Jalan Pantura Semarang - Kendal KM.12 especially when there was a shift of work shifts in terms of road capacity based on the Indonesian Road Capacity Manual. To determine the level of congestion if after provided worker transportation. From the data obtained, the largest VCR results in the Wijayakusuma Industrial Zone are 3.177 pcu / hour when the entry hours from the direction of Kendal are classified as the most jammed; in the Terboyo Industrial Zone is 0.917 pcu / hour when the hour enters from the direction of Demak; in the Temple Industrial Area is 0.875 pcu / hour when the hours go out towards Semarang are classified as quiet. After the workers of private vehicle users are transferred using buses, the largest VCRs are obtained from Type A buses with a capacity of 25 passengers, thus the value of VCRs in the Wijayakusuma Industrial Zone is 0.188 pcu / hour in the direction of Kendal; in the Terboyo Industrial Area is 0.066 pcu / hour in the direction of Demak; in the Temple Industrial Zone is 0.122 pcu / hour in the direction of Semarang. Planning to determine the number of buses that must be provided for each Industrial Estate, as well as efficient bus operating time.
