Abstract

The impact of the corrosion rate of diesel fuel pipes in PLTD HARUKU, DESA PELAUW. This study aims to see how much influence corrosion control has on the corrosion rate and remaining service life studied using an Ultrasonic Thickness Gauge. Measurements were carried out directly with an Ultrasonic Thickness Gauge. The measurement results showed that the highest corrosion rate was 0.0975 mmpy and the lowest was 0.0189. The remaining life of each pipe is determined by a formula that has been adjusted by the standard, with a higher corrosion rate causing a shorter pipe life, in the diesel fuel pipe the highest remaining service life of the IPA is 149 years due to the small corrosion rate while the pipe with the lowest service life is 25 years due to the high corrosion rate. Based on this analysis, the pipe is still feasible to operate. In conclusion, although there are variations in the corrosion rate, and the remaining service life of the pipe can still be operated safely. Keywords: Corrosion control, Corrosion, ultrasonic thickness gauge

Abstract

Crab skin is a processing waste that reaches 50-60% by weight intact, with a chitin content of 20-30%. If this waste can be utilized, then in addition to overcoming the problem of water pollution, it will also provide added value to the fisheries processing business. Until now, the use of these wastes is still very limited. Its use includes making petis, shrimp paste, flavor, and as a feed ingredient. This research is about the isolation of chitin from crab shell shells through the stages of demineralization and deproteination. The research method used in this study has 2 stages, namely deproteination with variations in NaOH reagent concentrations of 3.5%, 45.0%, 5 and 6.5%, and demineralization with HCl reagent concentrations of 1 M. Test characteristics of chitin and chitosan isolated results carried out with IR. The results of data analysis showed that the isolation of chitin from crab shells went through several stages, namely two stages of deproteination and demineralization stages. The optimum concentration of NaOH reagents used in the deproteination process is 4.50% with the concentration of protein that can be released in the first test of 18.0467 gr and in the second test of 17.8445 gr. The optimum concentration of HCl reagent used in the demineralization stage is 0.1 N. The optimum incubation time for the chemical deproteinas stage i is 2 hours with chitin levels produced of 32.8320 gr
