Abstract

One of the largest rubber glove companies in North Sumatra experienced fluctuations in the value of productivity and production costs incurred. From the observation of cost data, it was found that the realization of the company's production costs are still fluctuating and not linear to the level of productivity produced. This research aims to find out more about the level productivity and the effect of controlling production costs on these productivity. Measurement of productivity uses the formula of total productivity of input costs, while the method of multiple linear regression analysis is used to determine the coefficient of influence of the three cost variables, so it can be known which production costs are most influential on productivity. The results showed that the level of productivity of the company was good, an average of > 98%. The instability of the productivity level could be caused by factors of performance and availability of production machines. Based on the F test and t test, labor costs have the highest influence value among other production costs (raw material costs, overhead costs). Further research can consider other cost factors that affect the value of company productivity.

Abstract

Water is a natural resource needed to fulfill the livelihood of many people, so it needs to be protected so that it can be beneficial to the lives and lives of humans and other living things. Batam City is one of the cities in Riau Islands Province which has a type of soil that cannot store water properly so that it uses an artificial reservoir as a reservoir of rainwater. Due to waste from industrial, domestic and other activities that have a negative impact on water resources. Then testing the iron and zinc content of the reservoir water in the city of Batam was carried out. Metal Iron and Zinc are metals that are needed by organisms in relatively small amounts. Based on Government Regulation No. 82 of 2001 class 1, allowed Iron and Zinc levels of 0.3 mg/L and 0.05 mg/L. The method used in this test is Inductively Coupled Plasma - Atomic Emission Spectrocopy (ICP - AES), with the principle based on atomizing elements so that they emit light at certain wavelengths which can then be measured. From the test, it was found that the iron content in Duriangkang reservoir 0.2339 ppm, Sei Harapan reservoir 0.0299 ppm, Mukakuning reservoir 0.0292 ppm, Sei Nongsa reservoir 0.4168 ppm, Rempang reservoir 0.0001 ppm, Tembesi reservoir 0.0420 ppm, Sei Ladi reservoir 0.0588 ppm. Zinc content in Duriangkang reservoir is 0.0083 ppm, Sei Harapan reservoir is 0.0554 ppm, Mukakuning reservoir is 0.0083 ppm, Sei Nongsa reservoir is 0.0004 ppm, Rempang reservoir is 0.0083 ppm, Tembesi reservoir is 0.0083 ppm, Sei Ladi reservoir is 0.0211 ppm. This shows that the reservoir water has fulfilled the class 1 water quality requirements stipulated by Government Regulation No. 82 of 2001 except Sei Nongsa reservoir for the parameters of Iron (Fe) and Sei Harapan reservoir for Zinc (Zn) parameters.

Abstract

Fluids often experience a loss of energy (head loss) in the pipe due to flow turbulence, which results in friction on the inner surface of the pipe. Head loss is very detrimental in piping systems because it can reduce the level of fluid flow efficiency. Head loss is affected by variations in bends (elbows), joints, valves, and pipe diameters. The purpose of this study is to determine the head loss that occurs in each line of the fluid flow piping system, which consists of variations in the cross-sectional area of the pipe and the number of connections, valves, and bends. In addition, it is also used to evaluate pump work in series and complex circuits. The smaller the diameter, the more the fluid velocity increases, causing the friction in the pipe to increase and the head loss to increase. The pump work required to flow the fluid is directly proportional to the amount of head loss that occurs in the piping system.

Abstract

Crude Palm Oil (CPO) is obtained from the extraction process from palm fruit pulp. The extraction process is carried out at the press station. The working principle at the press station is to press the palm raw material in a hollow tube with a rotating screw so that oil will come out through the holes of the tube. The amount of pressure this tool can be adjusted electrically and depends on the volume of material being pressed. This tool consists of a cylinder with a hole in the inside there is a rotating screw. Press pressure is regulated by two cones (conus) located at both ends of the press, which can be driven back and forth hydraulically. Hydraulic pressure at 50-70 kg / cm3 commulator results in wet pulp, resulting in oil losses. The purpose of this study was to determine whether oil losses occurred at the press station in producing crude palm oil (CPO) at PT Perkebunan Nusantara III PKS Rambutan in Tebing Tinggi, North Sumatra by using the Statistical Process Control method. From the research, it is known that from the results of statistical process control (SPC) analysis, it is known that the level of achievement of standards expected by the company has not been achieved on fiber pulp. Where the results of the examination on the fiber pulp sample there are still quality factors that are outside the quality requirements or deviations occur. From the results obtained, it is necessary to propose improvements in performance, both from the quality of humans, machinery and raw materials for CPO processing.

Abstract

Paper is made from long fibers and short fibers whose composition greatly affects the strength of the paper, as well as filler to improve the texture of the paper surface. Reducing fiber loss and filler during paper production can save resources and reduce losses for paper mills. The most significant fiber loss and filler occur in the cleaner. For this reason an analysis of the effluent cleaner is done to find out how much fiber and filler are lost from the stock during washing. Filler determination was carried out by gravimetric method and determination of fiber was carried out by graff c staining test method. From the research that has been done to get fiber and filler which is wasted during washing around 0.1 %. Long fibers are wasted around 1.16-2.44 % and 97.56-100 % in the form of short fibers. This shows that the cleaner is still efficient in separating contaminants and fibers that are good for paper.
