INTEK: Jurnal Penelitian Vol 3 No 2 (2016): Oktober 2016
Publisher : Politeknik Negeri Ujung Pandang

Maintenance for machining and production facilityÂ is an important aspect to ensure a smooth production process.Â During this time, it was performed regular maintenance based onÂ technical advice from supplierâ€™s engines which just shows thingsÂ in general without considering the actual operating conditions.Â This paper aims to plan the maintenance strategies for the FinishÂ Mill unit based on reliability analysis by considering the target system reliability and cost of improving reliability. The data distribution obtained the most appropriate distribution. Based on the data obtained distribution parameters, then the function of the reliability of each part an be determined so that the value of the reliability of each part and the overall system for a specific time period can be calculated. The results showed that the failure or breakdown Mill Finish Unit was majority caused by the part of 561.BM1, 531.WF1, 531.BC6, 531.BC2, 531.BC1, 561.SR1 andÂ 531.BC3. it means that need to focus o the reliability analysis to allocate their parts.

The purpose of this study was to determine the temperature, time and the optimum size of the pyrolysis process to yield liquid smoke, and to know the grade of liquid smoke. Pyrolysis process were done by varying the temperature 350oC, 400oC, 450oC, 500oC, the time variation of 30 minutes, 60 minutes, 90 minutes, 120 minutes, 150 minutes, 180 minutes and a variety of fine size (3/8 inch), medium (1 inch), coarse (1.5 inches), after the analysis of pH, specific gravity, acid tertitrasi and total phenol content analysis. Liquid smoke that optimum results are calculated to determine whether the economic feasibility of this research can be continued at the industrial stage. The research showed the optimum temperature of 400oC at a yield of 45.5%, the optimum time of 120 minutes resulted in a yield of 46% and smoother optimum size at a yield of 47%. Total acid is between 6.8054% - 7.2746%, pH between 1.8 to 1.9 with phenol levels between 3.4456% - 4% in 1569 to produce liquid smoke to grade 4.

This study aims to analyze the evaluation of theperformance of transportation mode services and theperformance of transport route services to evaluate theperformance of the service level of integrated public transportsystems in the Masamba Region. The method of data collection isconducted through primary surveys and secondary surveys.Primary surveys are carried out by distributing questionnairesand data analysis techniques using SmartPLS version 3.0software and secondary surveys by collecting data related toresearch themes in several related agencies. The research sampleis that the public transportation passengers on the Masamba-Makassar Bus route as many as 98 respondents, determining thenumber of samples can be done using the Bernoulli formula.Based on the analysis of existing data obtained by respondents'perceptions that the performance of the level of service of thetransportation mode in terms of safety, comfort and orderlinesshas been effective, although in terms of equality it still needs toimprove its services. The performance of the Bus publictransport system in the Masamba area has also created anintegrated public transport system and the performance of theMasamba-Makassar PO route services is categorized well basedon the standards of public transport services from the DirectorGeneral of Land Transportation.

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
