Abstract

Tuna fish nuggets (Thunnus albacares) are easily oxidized so that the addition of purple cabbage flour (Brassica oleracea) is expected to improve the chemical quality of these fish nuggets. The purpose of this study was to determine the effect of adding purple cabbage flour on the chemical quality of tuna fish nuggets so as to produce tuna fish nuggets with the best quality. The research method used experimental methods and was designed using a factorial randomized block design with two factors, namely the concentration of purple cabbage flour (0%, 0.7%, 1.4%, 2.1%, and 2.8%) and storage time (0 days and 3 days). Parameters observed were water content, ash content, fat content, protein content, peroxide value and thiobarbituric acid (TBA). Parameter data were analyzed by analysis of variance at 5% significance level using SPSS 22 software and if there was a significant difference, further Tukey test was carried out. The results showed that the addition of purple cabbage flour concentration had a significant effect on the parameters of protein content, peroxide number and TBA, and the storage time had significantly affect the parameters of protein content, fat content, peroxide number and TBA.The chemical quality of the selected tuna fish nuggets was in the treatment of adding 1,4% concentration of cabbage flour without storage.

Abstract

More than 20% of the seeds sown did not germinate normally. The problem of low chili pepper seedling growth rates was caused by low germination rates. Internal factors contributing to low germination rates in chili pepper seeds had yet to be solved. This research aimed to analyze the effect of materials and duration of seed soaking of cayenne pepper (Capsicum frutescens) as well as the results of the soaking treatment for cayenne pepper seeds (Capsicum frutescens). This research used factorial Completely Randomized Design (CRD). The first factor, namely soaking material (P), includes control treatment or no  soaking treatment (K), warm water with a temperature of 50˚C (P1), KNO3 solution with a concentration of 1% (P2), and colchicine solution with a concentration of 0.1 % (P3). The second factor, namely duration of seed soaking (T), includes soaking time of 12 hours (T1) and soaking time of 24 hours (T2). There were 7 treatments with each treatment having 3 replications. This research carried out dormancy observations for 7 days. The data analysis for this research was in the form of quantitative data using Two Way ANOVA and DMRT further. The parameters observed included germination capacity, and germination rate. The results of this researc that 0.1% colchicine solution (P3) and 24 hour soaking time (T2) was the best materials and seed soaking for cayenne pepper seeds with 95% germination capacity.
