“…Electroplating aims to coat metal on a metal surface or a conductive surface through an electrochemical or electrolysis process, in order to produce a surface that is resistant to corrosion and improves the quality of appearance in terms of aesthetics [5]. Electroplating can be applied to various metal products such as vehicle frames, vehicle engines, and even household furniture, depending on the needs.…”

This research studied the corrosion resistance of low carbon steel that has been coated with nickel in NaCl solution by the Immersion Corrosion method with 3.5% NaCl liquid. Coating is done to increase the wear resistance of low carbon steel. The coating is done by electroplating process, with various voltages of 3V, 3.5V, 4V and 5V and the liquid is heated to a temperature of 44-60 o C in the immersion time range of 30 minutes, 40 minutes and 50 minutes for each voltage variation. From the results of the study, it was found that the longer the immersion time in the electroplating process, the thicker the resulting layer with the addition of about 4 8µm for each difference in immersion time.

The low-carbon steel alloy (St60 steel) consists of steel (Fe) and elements such as carbon (C), silicon (Si), manganese (Mn), phosphor (P), and others. This research aimed to analyze the corrosion rate of steel St. 60 by nickel coating in a corrosion test using 4M concentrated H2SO4 (sulfuric acid) with soaking solution for 60 minutes, 120 minutes, 180 minutes, and 240 minutes respectively. This research obtained by weighing the samples to find the weight losses after corrosion which resulted of 31.8 mg, 104.0 mg, 318.1 mg, and 575.4 mg for samples in 60 minutes, 120 minutes, 180 minutes, and 240 minutes soaking duration respectively. The corrosion rate calculation showed relatively significant weight losses. The average weight loss from the specimens in soaking time of 60 minutes, 120 minutes, 180 minutes, and 240 minutes were 0.0203 mm/year, 0.0320 mm/year, 0.0642 mm/year, and 0.0893 mm/year. The highest corrosion rate process was found in the soaking duration of 240 minutes, with the value of 0.0893 mm/year. The significant weight loss meant that soaking duration greatly influences the corrosion rate with the conclusion of longer duration resulted in a high corrosion rate and vice versa.

Nowadays, concrete is still one of the most used building materials, it had been improved whether in it’s quality or it’s mixture materials. There were a lot of studies that had been conducted to improve concrete that related to the produced compressive strength, stiffening speed, flexibility, etc. There are so many materials that can be used in concrete mixture to improve compressive strength. This study was conducted by using superplasticizer and reducing water amount in concrete mixture and aimed to find out how big it’s effects on the produced concrete compressive strength. Superplasticizer was used as admixture material wtih 1 percentage calculated by cement weight. Whereas water amount in concrete mixture was reduced by 0%, 15%, and 17,5%. The result obtained was that using 1% superplasticizer and reducing 15% water amount in concrete mixture produced optimum compressive strength of 22,98 Mpa.
