Abstract

Activity Testing the Effect of Antagonist Plants in Suppressing the Development of Incidence of Root Rot Disease Ganoderma sp. aims to determine the effect of antagonist plants in suppressing the development of stem rot disease incidence of Ganoderma sp. in oil palm nurseries. The study used a randomized block design with 7 treatments, namely Ganoderma+ginger isolate, Ganoderma+turmeric isolate, Ganoderma+lemongrass isolate, Ganoderma+temulawak isolate, Ganoderma+garut isolate, Ganoderma isolate and control. Each treatment with 5 replications with 2 sample plants. The parameters observed were the development of disease incidence through symptoms, height and number of leaf midribs of oil palm seedlings. The data were analyzed using the SPSS program. The effect of the treatment was analyzed by using fingerprints. If there is a treatment that has a significant effect, further tests are carried out with Duncan's Multiple Distance Test (DMRT) with a level of : 0.05. Based on the test results, it was found that the incidence of Ganoderma stem rot disease was the fastest, highest and most developed in each observation, namely in the treatment using ginger and lemongrass antagonists. While the lowest incidence of disease was found in the treatment of arrowroot, turmeric and temulawak. These antagonist plants have exudate containing antibiotics that can inhibit the growth of the Ganoderma fungus. The development of oil palm seedling plant height is strongly influenced by the physical properties of the soil and the presence of Ganoderma pathogens. While the Ganoderma pathogen did not affect the development of the number of leaf midribs, but only caused changes in leaf color such as necrosis.

Abstract

Identification of Escherichia coli and Salmonella sp. In Several Plantation Products, the aim is to explain the results of the identification test of E. coli and Salmonella sp. on plantation products. The research was carried out with 4 treatments and 2 replications. Each replication consisted of 5 dilutions. The treatments used were cocoa powder, compost, water and lettuce in selective growing media (EMBA and SSA). The parameters observed were to see whether there were E. coli or Salmonella sp. that grew in the four samples, the number of colonies and color changes that occurred as well as gas or bubbles produced in the fermentation test of sugars (glucose, sucrose and lactose). Based on the test results, it was found that E. coli and Salmonella were not present in the cocoa powder samples in EMBA and SSA media. In the compost sample, the bacteria E. coli grew on EMBA media, but Salmonella bacteria did not grow on SSA media. Lettuce samples showed E. coli growing on EMBA media, while on SSA media there was E. coli and Salmonella bacteria. Meanwhile, in water samples, E. coli, Salmonella and other bacteria grew on EMBA media. And on SSA media, Salmonella and Shigella bacteria grow. In the fermentation test of sugars such as glucose, sucrose and lactose, the media changes color to yellow and there are gas/air bubbles. This shows that bacteria can ferment carbohydrates and can produce gas. Salmonella and other bacteria grow on EMBA media. And on SSA media, Salmonella and Shigella bacteria grow.
