Abstract

The food processing industry, whether related to livestock, agriculture, or fishery products, often requires thickening additives to improve product quality. Salak trees are found around the Southern Tapanuli area of North Sumatra, Indonesia. Previous research showed the Midrib Sap Flour Salak Tree (TGPS) has fairly good quality content as a natural thickening agent but has not reported the quality of TGPS in terms of heavy metal content. Here, a study was carried out to determine the heavy metal content of TGPS. This research was conducted in January-March 2022 in Southern Tapanuli. The analysis showed that the metal content in TGPS does not exceed the threshold required in Indonesian Standard SNI 7387-2009.

Abstract

The purpose of this study was to see the effect of giving Vesicle Arbuscular Mycorrhizae (VAM) on the vegetative growth of white corn (Zea mays L), distance treatment of plant and interaction both of them on the vegetative growth of white corn. This study used a randomized block design (RBD) on factorial with two-factor and three replications. The first factor is the treatment of giving VAM (A) with various doses consisting of A1 (10 g/plot), A2 (20 g/plot) and A3 (30 g/plot), while the second factor is the treatment of plant spacing (J) with various sizes consisting of J1 (50 cm x 15 cm), J2 (50 cm x 25 cm) and J3 (50 cm x 35 cm). Data collection starts from planting to flowering, namely plant height, number of leaves, flowering time. Data analysis was carried out through analysis of variance and further test of DMRT at 95% confidence level. Based on the results of the study, it was found that the fungal treatment only had a significant effect on plant height and cob length, but did not significantly affect the number of leaves, flowering time. The plant spacing treatment only had a significant effect on plant height but had no significant effect on the number of leaves and flowering time. The interaction of the fungus treatment and plant spacing treatment showed that there was an interaction effect of the two treatments on plant height but did not significantly affect the number of leaves, flowering time. The treatment interaction A3J3 had the highest plant size of 114.55 cm.
