ABSTRACT Entomopathogenic fungi are classified as a fungus that infects insect pests. Hyphae color that comes out of the insect's body depends on the type of entomopathogenic fungus that attacks it. The purpose of this research is to explore, isolate and identify entomopathogenic fungi that attack insect pests. Samples of dead insects were taken from vegetable crops in the highlands of Pagaralam City and the lowlands of Ogan Komering Ilir Regency. In addition, exploration is also carried out using insect bait methods. This method is carried out on soils taken from the highlands of the fencealam area and Pekanbaru area. Based on the results of entomopathogenic expolation in vegetable plants that infect insects in the field there are 2 types of fungi that attack the insect. Two types of entomapatogenic fungi were found to have characteristics, namely the first hyphal color is rather green which covers the entire body of the insect and the second is white hyphae. The fungus that attacks the insect, then isolated to the GYA media found two entomopathogenic fungi namely, Metarhizium sp. and Beauveria bassiana. Meanwhile, through insect bait using soil T. molitor larvae, one species of entomopathogenic fungus was found, namely Metarhizium sp. The most infected T. molitor larvae in the soil of origin of Pekanbaru in the 2nd and 4th weeks, namely, 21.90 and 29.33 tails. . Keywords: Entomopathogenic Fungus, Insect Pest and Tenibrio molitor

Sugarcane (Sacharum officinarum L.) is a sugar-producing plant and is a food commodity that is needed by the people of Indonesia. National sugar demands are increasing every year. The low productivity of sugarcane is due to the competition of weeds which can reduce sugarcane production. To achieve high productivity, it is necessary to pay attention to the varieties used because they require certain conditions in their management. The purpose of this study was to determine the effect of varieties and types of weeds on the initial growth of sugarcane. The study was conducted from September 2018 to December 2018. The study used factorial Randomized Block Design (RBD) with two factors and four replications. The first factor consists of 4 sugarcane varieties, namely: Bululawang (V1), Red HW (V2), VMC (V3) and PS 862 (V4). The second factor type of weed consists of 2 types, namely Cyperus rotundus (N1) and Amaranthus spinosus L. (N2). The results showed that (1) There was interaction between the varieties (V) and the weed types (N) in stem diameter parameters and number of tillers, the treatment V4N1 gives the best response to stem diameter 1,31 cm and 4,25 number of tillers; (2) The treatment of varieties (V) gives affects to stem diameter and number of leaves, the treatment V4 gives the best response 5,38 to number of leaves; (3) Types of thorn spinach weeds can reduce the initial growth of sugarcane.

Rowopulo is one of the swamps in Gumukmas, Jember Regency with its unique soil in the form of peat soil that floats on water and by the community used for rice cultivation, whose production is influenced by the presence of Plant Pests, which is dominated by the Herbivod Arthropods. The presence of herbivorous Arthropods in the swampland rice ecosystem can be suppressed by the presence of useful Arthropod populations such as predators, parasitoids, and pollinators. Related to this, a study was conducted to find out the diversity of Arthropods found in swampy rice plantations. The study began with a land survey, then the determination and marking of observation plots on the map and matching these locations using GPS (Global Positioning System). Observations were made on plots that were made based on the extent of rice plants that were still in one stretch and the same irrigation flow. Each plot was observed ten times at 7-day intervals from rice plants aged 14 days after 77 days after planting. Arthropod sampling using sweep net method. Catching arthropods are put into vials of 5 ml size and then identified up to family level, and the diversity, evenness, and wealth index of the species is calculated. The results of research on swamp rice plants contained 37 families. Ten families act as herbivorous Arthropods, 15 families as predators, six families as parasitoids, one family as pollinators, and five families as detritivores. The highest diversity index in plot 1 was 2.95, while the lowest in plot 2 was 2.70, with the medium category for all observation plots. The magnitude of the diversity index is due to the dominance of only a few orders, such as Orthoptera and Diptera; the highest species wealth index in plot 3 with a value of more than 4 in the high category; Evenness index of all observation plots has a value of less than 1 with uneven categories. Keywords: arthropods, diversity, natural enemies, swamp land

Ginger (Zingiber officinale Rosc.) Is one type of rhizome plant commonly used as a medicinal plant or spice. The rhizome is aromatic and has a distinctive odor used by the community to be used as spices, cooking ingredients and medicinal sources. So far the results of ginger production have not been able to meet people's consumption needs due to a decrease in ginger production at the main ginger development center (West Java). One of the main constraints of ginger cultivation is the attack of bacterial wilt disease caused by the bacterium R. solanacearum. One effort that can be done in tackling bacterial wilt in ginger plants is by using clones that are resistant to bacterial wilt disease of R. solanacearum. The experimental design was carried out using factorial Completely Randomized Design, using ginger clones and the application of R. solanacearum bacteria. This design consists of 6 treatments and 4 replications. Each replication unit consists of 4 plants, so the total number of plants used is 96 plants. The experimental results were analyzed using regression correlation analysis on the parameters of disease progression, while on plant growth parameters using variance analysis and if there were significant differences then continued with Duncan Multiple Range Test (DMRT) with a confidence level of 95%. The results showed red ginger clones including rather resistant criteria with a severity value of 25% while ginger empirical clones and elephant ginger clones were critically vulnerable with 75% severity values and 85.42%. Red ginger clones are more responsive to the infection of R. solanacearum bacteria so that the highest phenol content increases compared to other clones of 0.297 mg/ml, the phenol compounds that play a role in increasing plant resistance. In the variable growth of ginger emprit clone plants have a higher plant height and number of leaves compared to other clones, namely 43.83 cm and 15.44.
