Corn (Zea mays L) is a very important food and animal feed after rice. One of the important pests that attack corn plants is Spodoptera frugiperda J.E Smith. This pest is a new pest and is a major pest in corn. In pest control, farmers generally use synthetic chemicals. In an effort to reduce these negative impacts synthetic chemical, entomopathogenic nematode (NEP) was chosen as one of the more environmentally friendly control techniques. This study aims to obtain NEP isolates, population density and virulence against S. frugiperda. This research was conducted at the Plant Protection Laboratory, Bengkulu University from December 2019 to April 2020. This study used a Factorial Completely Randomized Design (CRD) with 4 treatments and 5 replications. The treatments consisted of NEP concentrations : 0 Jl / ml; 200 Jl / 1ml; 400 Jl / 2ml; 600 Jl / 3ml originating from Bengkulu and Kepahiang isolates. Each experiment consisted of 3 S. frugiperda larvae. The results showed that the NEP obtained from each region, namely the genus Steinermatidae. Population density of 9,005 NEP / 5ml in the Kepahiang area and 6,837 NEP / 5ml in the Bengkulu region. NEP virulence test against S. frugiperda larvae showed that 200 Jl / ml concentration was able to control S. frugiperda in maize , and can kill pests within 4 days. With an LC50 value of 163.5 Jl / ml in Kepahiang isolates and 186.5 Jl / ml in Bengkulu isolates.

Banana is a horticulture crop that has economic value and is widely cultivated in tropical countries. Banana production in Bengkulu province reached 259,748 quintals, then durian (110,387 quintals), tangerines (94,396 quintals) (BPS 2015). Banana bunchy top disease caused by Banana bunchy top virus (BBTV) infection is considered the most crucial virus disease affecting yield losses of a banana plantation in Asia, Africa, and the South Pacific. However, the incidence and molecular characters of BBTV has never been reported in Bengkulu. This research aims to characterize symptom variations, disease incidence, and disease severity of BBTV infection in Bengkulu and virus detection using molecular methods by polymerase chain reaction (PCR). Disease incidence of BBTV was measured based on field symptoms. The disease survey was conducted in Bengkulu city, Bengkulu Utara district, and Rejang Lebong district. The study showed that the incidence of BBTV in Bengkulu City, Bengkulu Utara, and Rejang Lebong ranged from 0% to 100%. The most common symptoms observed in the field involved vein clearing, upturned leaf, chlorotic, and ragged margins, reducing petiole length, distance, lamina width, and stunting. Banana crops that are infected with BBTV in the vegetative phase will not produce fruit. In contrast, viral infection in the generative phase causes the formation of stunted fruit that is not suitable for harvesting. Thus, the potential loss of yield due to stunted disease can reach 100%. This study's results are the first reports of BBTV infection in banana crops in Bengkulu. Disease diagnosis will form the basis of disease control strategies in banana crops.

Based on oil palm yield data in Bengkulu Province, it shows several regions with varying production numbers. For this reason, it is necessary to group the potential oil palm producing areas to find out which areas produce palm oil in large or small quantities. Production shared is usually done based on the name of the oil palm producing district. Therefore, a method is needed to facilitate the grouping of oil palm producing areas. With the clustering approach, the division of regional groups can be carried out based on planted area and production. Analysis K-Means makes it easier to group an area with the largest, medium and low yields of oil palm. From the analysis results, it can be seen that the priority areas for oil palm rejuvenation in Bengkulu Province are Mukomuko District with locations in Air Rami, Pondok Suguh, Teramang Jaya and Penarik Districts.

Consumers’ preference level, especially on agricultural or food products, can be used as a benchmark measure or determine the market or shelf life of the product. This research aims to determine organoleptic quality through the level of people's preference for RGL citrus fruits coated with edible coating starch from cassava peel plus chitosan. Aplication of coating on the fruits and storage layout of this study was conducted following a completely randomized design (CRD) with 2 different factors; cassava skin starch concentration; namely 3%, 5%, and 7%; and chitosan concentration; i.e. 0%, 0.5%, 1%, 1.5%. The observed variables are the panelists’ preference level with organoleptic test on color, flavor, texture and taste of RGL orange that has been treated and stored at room temperature for 20 days. Research result indicates that the color of the orange that the panelists favored is absent; the level of panelist most prefer is neutral, if the starch is 3% with chitosan 0% (preference score 3.92); and if the starch 7% with chitosan 0.5% (score 3.44). The preferred aroma of orange is absent; the level of panelist highest preference on aroma is neutral, if the starch is 5% with chitosan 1.5% (score 3.12); and if the starch 7% with chitosan 0.5% (score 3.04). The texture of the orange is preferred to be absent; the level of panelist higherst preference on texture is neutral, if the starch is 7% with chitosan 0.5% (score 3.60); and if the starch is 3% with chitosan 0.5% (score 3.56). The taste of citrus fruits is preferred if the starch is 7% with chitosan 0.5% (score 4.00); and if the starch is 3% with chitosan 0% (score 3.44). Therefore, RGL citrus fruits can be stored at room temperature for up to 20 days, if it is coated with 7% cassava peel starch with 0.5% chitosan
