Abstract

Vitamins are essential compounds in food even though the content contained in these foods is small, and this is because vitamins have a vital role in the human body. Vitamin C or ascorbic acid is a secondary antioxidant compound that captures free radical compounds. Vitamin C content is easily found in vegetables and fruits. One of the fruits that contain vitamin C is guava. This study aims to determine and analyze vitamin C concentrations in several guava fruit types with the iodometric titration method. This type of research is a quantitative-qualitative experimental laboratory. The samples used in this study were guava in Myrtaceae family consisting of red guava (Psidium guajava L.), crystal guava (Psidium guajava L.), and red water guava (Syzygium aqueum). The study began with making 0.05 N iodine, iodine formation, then the 3% amylum indicators. The average sample content of red guava, crystal guava, and red water guava was 2.42 mg/100 grams. To conclude, the ascorbic acid concentration of red guava water is higher at 157 mg/100 g compared to the other two guavas, which are 80 mg/100 g and 87 mg/100 g.

Abstract

Chitosan in Penaeus monodon is a chitin compound removed from the acetyl group leaving a polysaccharide amine group and is polycationic through the chitin deoxidation process. The purpose of this study was to identify the potential use of chitosan adsorbent from Penaeus monodon (Chi-ShSW) on decreasing levels of copper (Cu) in electroplating industrial wastewater and to analyze the effect of variations in flow rate using chitosan adsorbents on reducing levels of copper (Cu) in electroplating industrial sewage. Chi-ShSW can be an adsorbent to reduce Cu (II) metal ions in the Metal Coating Industry wastewater. The adsorption test was carried out with a continuous flow system with different debits. The highest reduction in Cu waste in the study occurred at a flow rate of 215 ml/minute with a time of 84 minutes with a Cu content in the Metal Coating Industry wastewater of 1.227 mg/l and a reduction efficiency of 75.86%. The utilization of chitosan from Penaeus monodon was successfully synthesized as an adsorbent for the wastewater treatment of the metal coating industry. It can be concluded that Penaeus monodon can be used as an adsorbent to degrade Cu(II) metal ions contained in electroplating wastewater.
