In Indonesia, production of corn are used for fodder (55%), food (30%), and seed (15%). The growth of corn plants is limited by the presence of pests, weeds, and plant diseases. Curvularia sp. causing leaf spot and could decrease corn production. Use of mycorrhiza can be used as a biological agent in preventing pathogens outbreaks. Isolates of Curvularia sp. fungal was sprayed on corn seed. This research was conducted in laboratorium and green house. Corn seedlings were grown on sterile soil media (control), mycorrhizal treatments (100g of mycorrhizal + Curvularia sp., 200g of mycorrhizal + Curvularia sp., 300g of mycorrhizal + Curvularia sp.) and Curvularia sp. The observed variables were plant height, number of leaves, rate of disease progression, fresh weight and dry weight of plant canopy. The results showed that application of 100g inoculum tend to increase plant growth to 26-27% and percentage of mycorrhizal colonization to 58,66% thereof can decrease pathogen infection on plant at 28 day after planting.

Meat contaminated with bacteria has the potential to cause dangerous diseases when consumed by humans. One of the germs, especially bacteria that contaminate raw meat or meat with an incomplete maturation process is Escherichia coli. Therefore, E. coli needs to be minimized by inhibiting its growth. One natural way to inhibit the growth of E. coli is to test for antibacterials using liquid smoke. Liquid smoke can be obtained through the pyrolysis process from various biomass containing cellulose, hemicellulose, and lignin such as coconut shell (Cocos nucifera L.). Liquid smoke contains phenolic and acid compounds which are antimicrobial and antioxidant. This research uses the diffusion well method. Data analysis used Completely Randomized Design (CRD) with variance test (ANOVA). If the data had a significant difference at the 5% test level (P?5), the Duncan test was continued. Coconut shell liquid smoke is able to inhibit the growth of E. coli which is indicated by the formation of an inhibition zone. The concentration of coconut shell liquid smoke which effectively inhibited the growth of E. coli was a concentration of 50% with an inhibition zone diameter of 16.66 mm and MIC at a concentration of 10% with an inhibition zone diameter of 9.33 mm. Phytochemical test results of coconut shell liquid smoke contain positive phenolic compounds, flavonoids, triterpenoids, and saponins as well as phenol content of 2.403% and saponin content of 5.50%.

Along with increasing demand, eggplant production needs to be increased. Increasing eggplant production can be pursued by giving organic fertilizer with the right concentration. This research was conducted in April-August 2021 at the Green House of the Biology Study Program, FMIPA Udayana University. The research design used was a completely randomized design (CRD) with a 3x4 factorial pattern with 3 replications. The first factor is the type of organik fertilizer (A) with compost (A1), cow manure (A2) and goat manure (A3). The second factor is the concentration of organik fertilizer (B) which is 0 g/polybag (control) (B0), 500 g/polybag (B1), 1,000 g/polybag (B2) and 1,500 g/polybag (B3). Parameters observed is plant height, number of leaves, number of branches, flower initiation time, age of the plant at harvest, number of fruit crops, fruit length,fruit weight, and fruit diameter. Data were analyzed using Analysis of Variance (ANOVA) and continued with Duncan Multiple Range Test (DMRT) analysis. The results showed that the treatment of goat manure and a concentration of 1,500 g could increase all research parameters. The combination of goat manure with a concentration of 1,500 g gave effective results on the growth and production of eggplant.
