Abstract

BBTV (Banana Bunchy Top Virus) is a viral disease that attacks cultivated banana plants and can cause stunting. The symptoms of BBTV disease attack on banana plants are narrowed, piled up leaves and stunted plants. The disease is caused by an insect vector. Pentalonia nigronervosa is the vector insect that transmits BBTV disease. The purpose of the research was to see the java turmeric plant as an alternative host for population growth and BBTV disease vector. The method in the study used a Randomized Group Design. This treatment consists of two treatments with 10 replications. Based on the results of research conducted on the population of P. nigronervosa experienced fluctuations, but high growth in water media. BBTV disease that attacks banana plants in each treatment has the highest incidence in the control treatment, namely, 73.33% dan the lowest disease incidence the turmeric treatment was 6.67%. The highest intensity of BBTV disease attack in the control treatment was 42.06%, while the lowest in the Javanese turmeric treatment was 1.50%. P. nigronervosa inoculated on Javanese turmeric for 72 days can suppress BBTV disease transmission. However, based on the analysis of each treatment, no significant differences were found. P. nigronervosa has the highest population in the soil medium 95.4 individuals and water medium 86.7 individuals. The population of P. nigronervosa has a good development in turmeric plants.

Abstract

Chili (Capsicum spp.) are members of the Solanaceae family, which includes many cultivated plants. They are frequently used by farmers and have a spicy taste that makes them a popular ingredient in Indonesian cuisine.The objective of this study is to observe the effect of citronella extract on the inhibition of anthracnose disease caused by Colletotrichum capsici in chili plants.This disease, caused by the aforementioned pathogen, manifests as blackish-brown patches on the affected area. The affected area undergoes desiccation and detachment over time.The experimental design employed a Group Randomized Design (GRD) method, comprising six treatments (P0, P1, P2, P3, P4, P5), each repeated five times.The experimental treatment involved the application of citronella extract, varying in dosage concentration among the treatments. This research was carried out on the Agrotech Training Center land of the Faculty of Agriculture, Sriwijaya University.

Abstract

Rice is a staple food source for people in Indonesia Rice plants (Oryza sativa L.) are one type of hydrophytic spermatopyta plant. The method used in this research is the survey method, which involves directly visiting the land and conducting surveys in several food crop fields in Buay Madang Timur District, Oku Timur Regency. Observation of farmers' fields by observing disease intensity and the application of the concept of integrated pest and disease control. Additionally, by documenting the symptoms of disease attack and recording the results obtained through direct land observations. The results showed the calculation of the incidence of blast disease attacks in Srimulyo Village on land 1 to land 10 including the moderate attack category which is 44%, land 11 to 20 the lowest attack category is 20% and the category of moderate attack percentage is 46% and on land 20 to 30 the category of moderate attack with a percentage of 42%. As well as based on the calculation of the intensity of blast disease attack in Srimulyo Village on the 1st land to the 10th land including the mild attack category which is 15.5%, while on land 11 to 20 the mild attack category with a percentage of 19% while on land 20 to 30 the mild attack attack category with a percentage of 15.6%.
