Abstract

This study aims to analyze the marketing channels and efficiency of watermelon marketing in Paya Itik Village, Galang District, Deli Serdang Regency. The research location was chosen purposively, with watermelon farmers selected using purposive sampling, while marketing institutions were chosen using snowball sampling. Data were analyzed using both qualitative and quantitative descriptive methods. Qualitative descriptive analysis was used to examine the marketing channels, while quantitative analysis was employed to calculate marketing margins, farmer’s share, and marketing efficiency. The results identified three marketing channels, with the third channel having the highest marketing margin, while the first channel provided the highest farmer’s share. In terms of efficiency, marketing channels I and II for grade A watermelons were considered efficient, with marketing efficiency between 0-33%. This study offers insights into efficient watermelon marketing patterns and has the potential to help farmers improve profitability by optimizing their choice of marketing channels.

Abstract

Parmarion martensi is a major pest of cabbage crops, causing damage that reduces both quality and market value. The use of botanical pesticides as an alternative control method has not been widely studied. This study aimed to evaluate the effectiveness of extracts from Aegle marmelos (maja fruit), Azadirachta indica (neem leaves), and Carica papaya (papaya leaves) in controlling P. martensi. The experiment was conducted using a Completely Randomized Design (CRD) with 11 treatments and 3 replications. Treatments included a negative control (A0), synthetic pesticide (A1), and plant extracts at concentrations of 20%, 25%, and 30% (A2–A10). The results showed that neem leaf extract at 30% (A7) produced the highest mortality rate, reaching 93.3% at 5 days after application (DAA), with an average feed consumption of 0.39 g/day. Probit analysis indicated an LC₅₀ of 20.3% and an LT₅₀ of 3.6 days, suggesting a strong toxic effect. These findings indicate that neem leaf extract at 30% concentration has potential as a botanical molluscicide to replace chemical pesticides.

Abstract

Endophytic bacteria have the potential as environmentally friendly biocontrol agents in controlling bacterial leaf blight (BLB) in rice caused by Xanthomonas oryzae pv. oryzae (Xoo). This study aims to isolate, characterize morphology and biochemical tests, and test the antagonistic activity of endophytic bacteria from rice against Xoo. Isolation was carried out from healthy rice root tissue using a surface sterilization method. Morphological characterization included colony shape, color, edge, elevation, and Gram properties, while biochemical characterization included catalase, oxidase, motility, starch hydrolysis, and sugar fermentation tests. The antagonistic test used a dual culture assay method on NA (nutrient agar) media. The isolation results obtained six endophytic bacterial isolates (BETP 01–06) identified as the genus Pseudomonas and Bacillus with varying colony morphological characters. Antimicrobial activity test showed two potential isolates, BETP 03 (Pseudomonas) and BETP 05 (Bacillus), with an average inhibitory diameter of 16.3 mm and 16.5 mm against Xoo, respectively. Biochemical characterization showed that BETP 03 was bacillus, Gram-negative, citrate-negative, motile, gelatin hydrolysis positive, starch hydrolysis positive, and catalase positive; while BETP 05 was bacillus, Gram-positive, citrate-positive, motile, gelatin hydrolysis negative, starch hydrolysis positive, and catalase positive. These results indicate that both isolates have high potential as biological biocontrol agents in controlling bacterial leaf blight disease in rice.

Abstract

This research aims to determine the growth response of Cordyceps militaris in several growing media, determine the best growing media for cultivating Cordyceps militaris and determine the effectiveness of cultivating Cordyceps militaris against fire caterpillar larvae (Setothosea assigna). This research was carried out using a non-factorial Completely Randomized Design method, with 3 growing media treatments, namely N1 = Bran, N2 = Rice and N3 = Corn. The number of repetition was 6. Data analysis uses Anova, where if the results showed a significant and very siognificant effect, it was continued with Duncan’s Multiple Range Test (DMRT). The results showed that the growth medium had no significant effect on the density of yellow fungus and white fungus conidia, the viability of yellow fungus and white fungus condidia. The growth media of C. militaris is found in brand media, which is observed from the viability of fungus, both in yellow and white conidia, which can kill Setothosea assigna larvae which are marked in bran, rice and corn media at the age of 11-19 day after application, causing mortality between 93,34-100%,
