Abstract

This study aimed to find out the right extraction method to produce ketapang leaf extract with best phytochemical content and best inhibition ability against ice-ice causing bacteria. The experiment was conducted at the Laboratory of Fish Health, Environmental and Toxicology, from April to June, 2021. The experiment was designed according to a Completely Randomized Design (CRD) with 5 treatments and 3 replications. The three main treatments were, treatment A: extraction of ketapang leaves Terminalia catappa L. with 95% ethanol (extract A), treatment B: extraction of ketapang leaves T. catappa L. with 40°C water (extract B), and treatment C, extraction of ketapang leaves T. catappa L. with distilled water (extract C).  In the inhibition ability test, each extract obtained from the three main treatments was compared with two controls namely treatment D: positive control (Kanamicyn) and treatment E: negative control (aquadest). The phytochemical content data was analyzed descriptively, while the bacterial inhibition zone diameter data was statistically analyzed with Anova and LSD. The phytochemical analysis result showed that, the extract A contains alkaloids, flavonoids, triterpenoids and tannins,  while extract B and extract C contain alkaloid, saponin and tannin. The inhibition ability test showed that extract A gave the strongest inhibition (14.87 mm) against the ice-ice causing bacteria, and was significantly different from that of extract B (5.23 mm) and C (2.47 mm).  The inhibition ability of extract B was significantly different from that of extract C. The inhibition ability of the three ketapang leaf extracts (A, B and C) against the ice-ice causing bacteria was much weaker and significantly different from that of Kanamicyn (positive control).

Abstract

The aim of this study is to determine the effect of NaOH and KOH on carrageenan. The addition of natural dyes was carried out with different concentrations of carrageenan and the value of viscosity and gel strength of the algae Kappaphycus alvarezii to a mixture of natural dyes. The samples of algae were taken from the cultivation area in Belang waters, Southeast Minahasa Regency. The results of this study on the addition of natural dyes in refined carrageenan have succeeded in giving a green color and did not affect the viscosity and gel strength of the carrageenan gel when compared to the control (without treatment). The viscosity value of carrageenan with 4% NaOH concentration was 53.34-53.69 cP and KOH concentration was 49.55-50.03 cP. The gel strength value at 4% NaOH concentration was 74.11-74.89 mm/g/sec, while at 5% KOH concentration it was 84.22-84.89 mm/g/sec. The viscosity and gel strength still meet standards set by the Food Agriculture Organization (FAO).Keywords: Carrageenan, natural dye, Kappaphycus alvarezii, viscosity, gel strengthAbstrakPenelitian ini bertujuan untuk mengetahui pengaruh NaOH dan KOH terhadap karagenan.
