Abstract

The increase number of personal vehicle is not comparable with the growth of public transportation. Though the number of civil has increased rapidly and followed by the increase of people mobility from one place to another. This immeasurably mobility must be facilitated by public transportation in order that the traffic is not crowded by private vehicle.  Because of the increasing personal vehicle user’s, it will have an impact on improvident of using motor cycle  fuel along with it traffic jam that causing time and costs improvident and it is also makes an environmental pollution. Therefore, the growth of public transportation on the city must be held as soon as possible in order to respond increasingof the townspeople, increasingthe number of people mobility from one place to another andincreasing the motor cycle user’s.

Abstract

The lot deposit of Domato Stone as local material from sea location in Banggai island in half Sulawesi of Indonesia. Was still not be exploited better. Some reseaarch in the field of road construction showed that Domato Stone was powefull enough when mixtured asphalt structure. Permeable asphalt pavement or porous friction course is commonly knows as porous asphalt. The porous pavement used in japanes and europe. The pavement consists in a porous overlay allowing rainwater to flow down to the botton the overlay and then to drain on the edges of the pavement. Quality of porous asphalt was developed to drain pavement surface flow through it’s pores, because of is specific propertis to mesure it’s ability to drain the water ( Permeability ), a special measuring device is required. This study is aimed to measure the coefficient of permebility using the constanthead permeability test at transportation laboratory Hasanuddin University. The result were compared with the previous study. The test included horizontal and vertical permeability. There types of gradation were in comporated to : British Graduation, Binamarga Gradation, and Australian Gradation. The tests were carried out at optimum bitumen content, the result shows that the vertical permeability of porous asphalt usig British Gradation were : 0,0914, 0,2841 and 0,2912 Cm/sec. Respectively meanwhile for horizontal permeability were 0,1168, 03212, 0,2897 Cm/Sec. The Marshall stabilities were at in countary to the permeabilities, the porousity were comparable to the permeabilities. The results of research indicates that porous asphalt mixture showed an influence on the value of the characteristics of porous asphalt particularly at concrete waste fraction grading 50% retained 1/2 " and 50% natural crushed stone retained 3/8" where the values obtained from the analysis of optimum binder content is 9.5%. Based on the Scanning Electron Microscope (SEM) can be seen the microstructure and content of chemical elements present in the porous asphalt which prove that all elements of the liquid asbuton and concrete waste can blend and bind well.

Abstract

Land use and land cover change in a watershed might drive some impacts, such as high amounts of discharge fluctuations. Way Kuala Garuntang Watersheed is one of watershed in Bandar Lampung that has changed significantly. This study analyzed land use and land cover change to determine how much its influence on discharce fluctuations based on Geographics Information System. The method used in this study comprised of hidrology, spatial and sensitivity analysis. Hidrology analysis based on daily rainfall data. Spatial data analysis aims to present geospatial data related effects of land use and land cover change on the value of discharge. Sensitivity analysis is done by creating a land use and land cover simulation scenarios and sees its effect on the peak discharge events. The results of hidrology analysis in this study showed that the rainfall data obtained from the rainfall stations around the watershed were inconsistent and it needs to be repaired. It was found that the pattern of rainfall distribution in Bandar Lampung for 4 hours consists of 40%, 40%, 15% and 5% pattern. The results of spatial analysis in this study showed that there are 11 types of land cover on the existing condition and only has a protected area covering 4.72% of the total watershed. From the results of the sensitivity analysis showed that land use scenario with availability less than 30% of the area of green open space watershed may cause an increase in the value of the peak discharge. Instead, the scenario to maintain a 30% green open spaces of wide watershed did not make a significant change in peak discharge. This action is necessary to provide enough space for the infiltration of rain water on a particular area for the purpose of supplying the needs of ground water and flood control.

With global awareness of environmental risk and the pressing needs to improve efficiency, manufacturing systems are growing into new concept. Green manufacturing is reflected to employ various green strategies and technique to produce with eco-efficient. Green manufacturing aspects on the machine level  were studied in various machining process.  On this paper presents the green manufacturing review of Rapid Prototyping process. The objective is to evaluate the factors involved in green process of RP. Several comparative RP process respect to green manufacturing criteria are described.Rapid Prototyping process uses three dimensional CAD files to fabricate a physical model. Models are usually made from variety of material such as ABS, rubber and specific metals. Each material has the environment impact during the process and recycling. RP process are known as process not suitable for making direct product. However, lates technology makes it suitable to produce the parts with reasonable cost. For near the future, the utilization of this technology is becoming increasing and green manufacturing effect should be considered.  Based on study conducted, several type of RP process is eco-efficient due to amount of waste material produced and environment impact during the process.

Abstract

Nowadays, the computer’s technology is growing so fast and affects the human’s life. With computer, people can do something easier, faster, more efficient, and so on. At SMAN Bandarlampung, the time schedule for teaching process is still done manually. One person is in charge of doing and making the time schedule so that all the lessons, time, classrooms, and days are supposed to be fixed and suitable for every teacher. However, this is not easy to be done, because there are some factors also that must be considered, for example: teacher who also put in structural position such as headmaster or vice headmasters. Besides, under Indonesian’s regulations, the teacher whose certificate to educate must teach at least a certain hour per week. Therefore, in order to handle this condition, we design and develop a system so that the problem can be solved easily. We use the concept of edge coloring to match the schedule. The data are divided into three sets: the set of active time, the set of classes and classroom, and the set of  teachers’ obligation (which include : the data of teachers and their subjects/lessons, and how many time/hours needed to teach for every teacher. The system developed is running well and we will be discussed in the paper.
