Ant nests (Myrmecodia sp.) are one of the medicinal plants that have many benefits for health. Ant nests are widely used as antimoicrobial, antidiabetic, anticancer and antiimplantation because ant nests usually contains chemical compounds such as flavonoids, terpenoids, saponins and polyphenol tannins. Flavonoids can be used as antioxidants, antiangiogenic, and antimicrobials. Many products can be developed from the extract, such as tea, powder and ant nest capsules. Another product innovation that needs to be developed is gum. It is important to conduct research to determine the optimum formulation of ant nest extract as an additional ingredient on candy products (gum). This study aims to determine the antimicrobial and antioxidant activities of ant nests extract and maximize the use of ant nest extractas at additional raw material for high quality gum. The ant nests were extracted using 70% ethanol. The concentrated extract was tested for antimicrobial activity in four types of pathogenic bacteriaEscherichia coli ATCC 25922, Staphylococcus aureus ATCC 6538, Streptococcus mutans ATCC 25175, Pseudomonas aeruginosa ATCC 9027, and Salmonella typhimurium ATCC 14028); antimicrobial positive control was tested using chloromphenicol and antioxidant activity positive control was tested with ascorbic acid (vitamin C). Dried ant nest extract was added to the gum mixture as much as 0.15% and 3% and then the quality was tested based on the parameters according to the quality standard of gum. The results of this study showed that ant nest extract had effective antibacterial activity in gram-positive and gram negative bacteria with an inhibitory zone of 10-13.5 mm. The high antioxidant activity of ant nests (85.90%) proven that ant nests had the potential as an natural antioxidants added in food. The addition of 0.15% and 0.3% extracts in chewing gum generally produced gum that met the quality standards of chewing gum, although the moisture content was slightly higher than the maximum limit of the standards.

The objective of this research was to analyse organic fertilizer pellets from water hyacinth and oil palm empty fruit bunch (OPEFB) that have not been widely used in South Kalimantan. The variable of the research was the ratio of water hyacinth and OPEFB: 25%:75%, 50%:50%, and 75%:25%. The fertilizer was produced by heating the materials at 350oC, and then composting the materials using effective microorgnism 4 (EM4), and then mold into pellet shape. The results showed that the drying, heating, and composting process could increase nitrogen and phosphor content. Nitrogen in water hyacinth increased from 0.06% to 2.18%, while its increased from 0.18% to 2.49% in OPEFB. Phosphor in water hyacinth increased from 3.42% to 6.89%, while its increased from 1.95% to 4.70% in OPEFB. The quality of organic fertilizer pellet was evaluated according to Permentan No.70-2011. The result showed that the content of C-organic, macro nutrients, micro nutrients, heavy metals, Escherichia coli, Salmonella sp., moisture content, pH, and residue met the requirements. The organic fertilizer contained the highest nutrient made from 50 % water hyacinth and 50% OPEFB.Keywords: organic fertilizer pellets, oil palm empty fruit bunch, water hyacinth
