Abstract

Prima XP SAE 20W - 50 is a multigrade lubricant used for gasoline and Medripal 412 engine lubricants used for marine industry engines which are non-carcinogenic and environmentally friendly. The main factor in testing lubricants is the Blending process, which is the process of mixing base oil with additives. In the blending process, an inhomogeneous lubricant was found which caused the lubricant test not to comply with specifications. This experiment aims to determine the optimal time of the blending process with the KAN homogeneity test method. Homogeneity testing can be seen from the viscosity value of the lubricant. So the optimum time for the blending process is needed for the continuity of the production process of this lubricant. Medripal 412 products have an optimum blending time of 30 minutes with a viscosity value at 100 C ranging from 14.79 mm2 / s based on the SNI 7069.1 Th. 2012, the product specification value of Medripal 412 is 12.5 - <16.3 mm2 / s and the Prima XP SAE 20W - 50 product has an optimum blending time of 45 minutes with a viscosity value at 100oC of 20.28 mm2 / s based on the SNI 7069.1 Th. 2012, the value of the Prima XP SAE 20W - 50 product specification is 5.6 - <21.9 mm2 / s. This shows that the lubricant is by the standard quality standards set by the company and the government so that the lubricant product is still suitable for use.

Abstract

PT X is one of the Reviews largest ethanol producing plant in Indonesia, PT X located ± 15 km the northeast of Solo or 110 Km to the south of Central Java, SeAprilang. Cooling Tower is a tower or building of water circulation directly or indirectly contact with hot water and then converted into cold water expected that a number of heat from a fluid to another fluid. The Cooling Tower operates According to the diffusion principle, where temperature changes can result in a difference in the rate of temperature displacement. From the process in the cooling tower unit there are Several variables contained in the cooling towers ranging from the temperature and water conductivity in the hot basin. Obtained from the variables can be used to analyze the effectiveness of the cooling tower unit. When the conductivity contained in the water in the basin of hot high then the effectiveness of cooling tower will Decrease, likewise vice versa. And the value of effectiveness Obtained range of 76.12% - 87.80%. Where the company's standard value is 75% effectiveness. There are Several factors Determining the high value of conductivity values such as chemical mixing, high temperature in the cooling tower, and the temperature around the cooling tower.

Abstract

PT Champion Kurnia Djaja Technologies' role is to produce oil field chemical products on a large scale and then used in applications in the petroleum industry. Petroleum is a fuel derived from fossils. Microorganisms living in the ocean. When these organisms die, their remains will settle to the bottom of the ocean and be covered in mud. Demulsifier or oil field is one of the specific chemicals to separate emulsions for example a mixture of water, petroleum. Product selection is done to analyze the quality of crude oil. The method used for analysis is the bottle test demulsifier in the laboratory by entering 40% water and 60% oil into saniglass and allowed to stand in the water bath and then injected with the chemical that has been observed, then 15, 30, 45, 60 minutes with Note the changes in the water drop, interface, and clarity of each sample, if not optimal, phase 2 testing will be carried out with the bottle test method and get the optimal West Benakat sample results by injecting chemical 1 + 3 the results are sharp interfaces, clear clarity and The BS&W is dry oil, while the Talang Akar sample is optimal in chemical 2 + 3 because the interface is sharp, the clarity is clear and the BS&W is dry oil.
