Abstract

The demand for accessible parking services and facilities are growing in the University of Singaperbangsa Karawang (Unsika). This occurred due to the increasing number of vehicles need parking spaces. Some problems can happen because of scrambling over the space, the improper of parking lot building, the ineffective actions in allocating and checking the traffic signs, and the unavailability of traffic signs. The focus of this research was the campus community who use the parking lot. They became the object of the research. The data analysis was used to determine the level of the satisfaction of the campus community towards the service quality and parking facilities in Unsika using the Wilcoxon Signed Rank Test method with Statistical Product and Service Solutions (SPSS) application. The results showed that the campus community was complaining about the quality of service and parking facilities. The perceptions were given in the form of negative perceptions because it was not in line with expectations. The respondents were hoping that the university would pay attention to the quality of services and facilities.

Abstract

HVU III is designed to process reduced crude oil from CDU V or reduced crude from export oil existing tanks. HVU III is one unit that aims to lift light fractions that may still be contained in reduced crude. The vacuum condition is designed to attract mild fractions at relatively low temperatures. With the effort to take the product slop wax as HVGO, indeed the operating condition is changing and there is addition of equipment (Pump and HE) and modification of piping. Therefore in this study about design HE (Cooler) with slop wax product as HVGO which will be cooled from temperature 298oC to 70oC with flow rate 40 m3 / hr. And as a cooling medium used Sea Water (sea water) from temperature 30oC to 38oC. Pressure slop wax 20 kg / cm2 and sea water 4 kg / cm2. The calculation results for cooling the wax slop requires a Cooler of 6 (six) units with a seawater requirement of about 709187.39 lb / hr, and heat transferred in a fouled state of 0.0029 hr ft2 F / btu. Pressure drop for slop wax equal to 7.08 psi while sea water equal to 39.33 psi. Under these conditions it is expected that the addition of equipment in this case Cooler can be done as an effort to take the product of slop wax as HVGO.

Abstract

Cellulose is one of the largest components in corncobs. Cellulose was obtained from corncob in this research that has a yield of 19.6% of 20 grams of corncob powder. The isolated cellulose was characterized by using FTIR and SEM. Cellulose has crystalline chain and insoluble in water or organic solvents. The molecular chain of cellulose is linear and has intra- and inter-molecular hydrogen bonds. One way for cellulose to be easy in the treatment of applications, is to convert microcrystalline cellulose into nanocrystalline cellulose. Nanocrystalline cellulose can be obtained by several methods, one of them by acid hydrolysis. Hydrolysis of cellulose by using sulfuric acid produces nanocrystalline cellulose. Nanocrystalline cellulose can be characterized by using TEM and PSA analysis. CNC 60 has a particle size distribution with a diameter range of 14.3 nm - 45.0 nm and an average diameter of 17.4 nm. Whereas cellulose with CNC 90 has a smaller particle size distribution with a diameter range of 10.0 nm - 17.1 nm and an average diameter of 11.9 nm.
