<![CDATA[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.]]>

<![CDATA[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 itâs pores, because of is specific propertis to mesure itâs 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. ]]>

<![CDATA[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.]]>

<![CDATA[One of the software development standards in use today is the Capability Maturity Model Integration (CMMI) of the Software Engineering Institute (SEI) and ISO 9126 .Based on the 2009 survey conducted by PornchaiMongkolnam, in Asia there has been a 1,901 CMMI appraisal, to the North American continent as 1328, as many as 536 Europe, and South America 289 CMMI assessment. In India alone there has been a 409 CMMI appraisal, including three world ranking, making India the more trusted by the world International for application development. Meanwhile in Indonesia CMMI implementation is not too meaningful. Only a mixture of two companies (foreign and local) that implements it. That was probably due to the application of the mandatory in the meet (mandatory) from its headquarters abroad or indeed the company began to enter into foreign markets that require CMMI certification. This study seeks to help measure the maturity of software development using an integrated approach between CMMI and ISO 9126 in a local development company. Hopefully this can be more give their views so as to facilitate its peers able to take to implement the same thing.ISO 9001 is a standard for quality management systems while CMMI is a model for process improvement. If an organization that has achievedISO registration wishes to improve processescontinuously, CMMI can be a strong candidatebecause it provides a more detailed roadmap forprocess improvement. However, with respect toadopting CMMI in organizations that are familiarwith ISO 9001, there are some issues that need to beresolved. For example, ISO 9001 and CMMI havedifferent targets, intent, and quantity of detail. In thispaper, we present an integrated model of ISO9001:2000 and CMMI and ISO 9126, which would resolve the aboveproblems. We expect that this model will be a usefultool for ISO registered organizations aim to attainhigher CMMI levels. ]]>

<![CDATA[Studies on the influence of magnetic fields on plant growth and development provide a promising prospect in the field of agricultural engineering. But there are still many obstacles encountered, because the plant response to the magnetic field treatment varies depending on the strength, intensity, and duration of exposure. Type, age, as well as parts of the plant are used also gives a different response to magnetic field treatment. Previous studies showed that a magnetic field can increase the germination of some seeds of agricultural crops. In this study, The entire treatment duration of exposure 0.1 mT magnetic field causes an increase in a-amylase activity in all legume seedlings observed. Fluctuations in enzyme activity during the germination of kidney bean seedlings are relatively the same as the black turtle bean, as well as enzyme activity in soybean and mung bean. But between the two groups of seedling legumes (kidney beans and black turtle beans vs. Soybeans and green beans) show a very clear difference fluctuations enzyme activity during germination]]>

<![CDATA[Each company must carry out product development to maintain or build sales. Relationship between specifications and parameters of quality products to the wishes of the customer is an important consideration in doing product development. Product development methods QFD (Quality Function Deployment) has been widely applied in industry to maximize customer satisfaction based on quality, cost, time and other, become source of constraints. Quality, time and cost are important factors for a company to maintain existency of the company in the industry. This study will provide customer deployment requirements to consider not only the quality factors are more often a point of view assuming the successful development of a product, but also on the factors of time and cost. Factors to be considered in stages creating new products or improving old products are not only detailed data about the four phases of phasing as product planning, product design, process planning, process control and planning is needed, but also a complete view of the overall technical response . The final integration of the four phases of QFD is influential in producing and marketing the products. Team of product development must plan how to design new products to exploit existing technical response. Matters relating to the quality characteristic and the voice of stakeholders is very relevant and should be well understood and thoroughly. Technical approach to a more detailed response can lead a team of product developers to pay attention to the changes of each phase to obtain the allocation of resources for each of the responses are perfectly. ]]>
