Abstract

The Special Efforts Program (Upsus) is an Indonesian government program to increase production/productivity of lowland rice to support the realization of food self-sufficiency. The Upsus targets are to increase the planting index by 0.5 and productivity by 0.3 tons/ha/GKP. The increase in planting index is achieved by the expansion of added planting, but the increase in productivity has not been reached optimally due to pest and disease attacks. The objective of this research was to determine the knowledge, attitudes, and actions of Upsus farmers in controlling pests and diseases, rice cultivation techniques, and implementation of Upsus in Karawang District. The research was conducted by distributing questionnaires to 60 farmers in Tempuran and Tirtajaya Sub-District at Karawang District. The respondents were selected by purposive sampling with the consideration of respondent being an active farmer, having at least 5 years of farming experience, and has ben a member of Upsus for at least 1 year. Most respondents have age in the range of 41-60 years, the highest education of elementary school, and have farming experience for 5-10 years. Pests and diseases are the biggest problems faced by the farmers. Upsus farmers used Ciherang and Inpari 32 varieties and the applications of pesticides were conducted according to the schedule. Most of the farmers could not distinguish between pests and diseases. The dominant pest and disease control carried out was the use of chemical pesticides. Keywords: diseases, pesticides, pests, Upsus

Abstract

Porang is one of the export commodities whose production is currently intensive by the Indonesian Government. Soft rot disease is one of the obstacles in cultivation and post-harvest of porang, which results in a decrease in productivity and quality of porang. This study aims to isolate pathogenic bacteria that infect porang tubers and determine their morphological and molecular characters. A total of 43 bacteria were isolated from porang tubers with soft rot symptoms from Malang Regency. Ten isolates of them showed positive reactions in the hypersensitivity test. Amylolytic, pectinolytic, mannanase, and proteolytic activities were shown by three bacterial isolates, including B4, B7, and BLUB15, by forming a clear zone around the inoculation point. The results of the decay test showed that B4 isolate had the most severe signs of decay, up to 97.88% in potato tubers and 37.12% in the porang frog. A pair of ExpccR/ExpccF PCR primers successfully detected B4 isolate as Pectobacterium carotovorum subsp. carotovorum (Pcc) in the 550 bp band. Unexpectedly, identifying the other two isolates did not show any similarity to the bacteria that cause soft rot, which was previously known. The two isolates showed similarities to Empedobacter sp. B7 (98.7%) and Pseudomonas sp. BLUB15 (97.6%) as a result of 16S rRNA gene analysis. So far, based on the existing literature, this is the first report of phytopathogenic bacteria causing soft rot outside the genus Pectobacterium and Dickeya.
