The quality of maize grains was markedly affected by critical storage conditions, such as high relative humidity and high temperature. This experiment was performed to estimate quality of maize seeds (Zea mays L.) after ageing during 2020 season. Two-factorial experiment was performed with completely randomized design with three replications, using four maize hybrids (SC10, SC132, TWC360 and TWC368) and four levels of accelerated ageing (non-aged, artificially aged for 2, 4 and 6 days at 45o C temperature and 95% relative humidity).  Germination percentage, mean germination time, electrical conductivity, shoot and root lengths, seedling dry weight, seedling vigor index, protein content, oil content, and activity of catalase and peroxidase enzymes were measured. The results showed that, responses of varied parameters to aging periods were significantly different in all traits. When aging time increased, there was a depression in all traits except for mean germination time and electrical conductivity which were increased. In addition, the studied traits were significantly different due to diverse maize hybrids. TWC368 was superior compared with other hybrids in most of the measured traits

Indonesia has very high fishery commodities production. It also has the potential to increase the economic condition of coastal communities. Grouper commodity contributes greatly in increasing the country's export. One obstacle that still affects the export is the quality of grouper commodities. Indonesian grouper often deals with parasitic infections. This study aimed to determine the type and prevalence of parasites that infect grouper commodities both cultivated, consumed and as ornamental fish in Buleleng Regency, Bali, Indonesia. Descriptive analysis was used in this research to clearly explain the prevalence of the infection. The results showed that 80 collected and examined grouper samples in fry, consumption, and ornamental commodities, nine samples were found to be positively infected. The type of parasite found was Trichodina sp. and Diplectanum sp. with a total prevalence of 11.25%. The target organs infected in tiger grouper (Epinephelus fuscoguttatus) commodities were gills and fins, showing the potential of quality reduction caused by parasite infection in grouper commodities. Prevention and curing action should be carried out to reduce further loss potential in the commodities of grouper in Buleleng, Bali
