ABSTRACT In the conventional machining process, production costs are very necessary to know in order to determine the cost of making a product in each manufacturing industry, such as the Machining Workshop at SMK N 2 Pekanbaru. Machining production costs are calculated based on machining time per product and machining operating costs. In calculating conventional machining costs, Macro VBA Exce…
ABSTRACT This study aims to analyze the production process at the press station using the Overall Equipment Effectiveness (OEE) method and determine the maintenance time for screw press machine components in the case study of PTPN V Sei. Galuh. OEE is a method used to measure machine availability, performance and quality. Then, this research was continued with the Mean Time To Failure (MTTF) a…
ABSTRACT Fatty acid methyl esters play a major role in the oleochemical industry. Methyl esters replace fatty acids as starting materials for many oleochemicals. Another potential use of methyl esters is as a substitute for diesel oil. Methyl ester is clean combustion without sulfur dioxide emissions. Even though the combustion heat is slightly lower, no engine adjustment is required and t…
ABSTRACT Qurban (sacrifice) is an activity carried out during the celebration of Eid al-Adha, and it is obligatory for those who are financially capable to perform this religious ritual. The process of sacrificing animals for qurban encounters issues due to frequent accidents caused by non-compliance with standards, making it prone to accidents. Moreover, the limited space in urban areas poses…
ABSTRACT The screw press machine is a tool commonly used to crush fruit and then separate the crude oil from the flesh of the palm fruit. The worm screw in the screw press is one of the main components in the machine for extracting CPO (Crude Palm Oil) / crude palm oil from fresh fruit bunches. The screw press machine can experience damage in its operation and interfere with machine performanc…
ABSTRACT One of the areas in Riau Province that produces areca nut is Idragiri Hilir Regency, especially Kembang Mekar Sari Village, but the cleavage process still uses the manual method so that the resulting production cannot be in large quantities. The purpose of this research is to design a areca splitting machine that is in accordance with the wishes of the community so that the areca spli…
ABSTRACT Hydrazine is an inorganic compound in the form of a colorless flammable liquid with an odor like ammonia.
