Along with the increasing needs of people inMakassar city for the mode of transportation, the number of thegrowth of motor vehicles that operate on the road becomes largerthan the growth of the number of roads built. This has causedsome problems in the transportation sector. In addition tocongestion problems, problems arise from road surface damagedue to increasing traffic loads that must be borne by the roadsurface. To anticipate this, some strategic streets in the city ofMakassar then designed by using a rigid pavement that hasgreater strength in carrying the burden. Another problem thatarises from the growing number of motor vehicles that operateon the road is greater than the growth of the number of roadsbuilt is the higher levels of noise pollution or traffic noise. Noise issourced from the sound of a vehicle engine and the frictionbetween the vehicle tire and the road surface. So that roads withrigid surface pavement surfaces that have a rougher surfacetexture, potentially lead to higher noise levels. This study aims todetermine how much noise levels that occur in roads that userigid pavement in the city of Makassar. The road segments, suchas Jl. Abd. Dg. Sirua, Jl. Batua Raya and Jl. Adhyaksa. The toolused to measure traffic noise is the Sound Level Meter (SLM).The survey was conducted for 1 day for each of the roadsegments reviewed. The data taken are the level data of flatnessof road surface, vehicle speed data and traffic noise level data.Data processing is done by analyzing the relationship between thefactors that affect the noise with the noise level that occurs on theroad with rigid pavement. The results of this study are expectedto provide information about how big the effect of vehicle speedon the noise level that arises on the road with rigid pavement.Keyword--Noise; speed of vehicle; Rigid Pavement

Polytechnic is a university that organizesvocational education in various science and technology clusters.The learning process in polytechnic is dominated by practicumthat is 70% and 30% theory. The amount of laboratorypercentage affects the large number of laboratory. Eachlaboratory has a laboratory responsible (technician) in charge ofrecording and monitoring the completeness and condition of thepracticum equipment. Tools and materials used in the process ofpracticum is an asset and laboratory inventory that must alwaysbe maintained and checked the condition of the equipment. InUjung Pandang State Polytechnic (PNUP) in terms of assetmonitoring and practicum inventory is still done manually.Therefore need to make an application to monitor assets andlaboratory inventory, especially on campus two. It is known thatsince 2014 there are three departments that have implementedthe teaching and learning process in two campuses includingseveral laboratories have also been transferred to the twocampuses, such as electrical engineering majors, majoring inbusiness administration and accounting majors. So with thisapplication will greatly help technicians because no longer do thereporting or request tool manually and with this application inmonitoring the condition of the tool is damaged and tools thatneed further improvement more easily and can be quicklyupdated. The creation of this system begins with the needsanalysis, design design as the basis of system development, theright of access consists of technicians of each laboratory andprocurement department on campus one, content creationconsists of laboratory data, checking tools and materials, repairtools and materials and demand tools and materials then printdata laboratory
