Abstract

Tujuan penelitian ini adalah mengetahui pengaruh pemasteuran medium digabung dengan agensia hayatidan agensia hayati yang paling efektif terhadap penyakit busuk hati. Penelitian dilakukan di PT NusantaraTropical fruit, Lampung Timur dengan rancangan Petak Terbagi dan diulang tiga kali. Petak utama adalahmedium dipasteur atau tidak. Anak-petak adalah control dengan air steril, Trichoderma harzianum isolat jahedan pisang, Pseudomonas fluorescens P60, dan Fusarium equiseti diisolasi dari akar pisang. Peubah yangdiamati adalah masa inkubasi, intensitas penyakit, populasi konidium Fusarium akhir, akar berpotensi terinfeksi,tinggi tanaman, jumlah daun, jumlah akar primer dan sekunder, panjang akar, dan berat akar. Hasil penelitianmenunjukkan bahwa perlakuan gabungan memberikan hasil positif khususnya menurunkan intensitas penyakitsampai 43,57%. Agensia hayati T. harzianum isolat pisang dan P. fluroescens P60 yang digabung denganpemasteuran medium dapat menekan intensitas penyakit masing-masing sebesar 63,08 dan 59,75%. Agensiahayati yang paling efektif adalah T. harzianum isolat pisang karena menekan kepadatan Fusarium, meningkatkantinggi tanaman, dan meningkatkan berat akar masing-masing sebesar 41,12, 39,00, dan 98,86%.Kata kunci: busuk hati, bibit pisang, pemasteuran, agensia hayati ABSTRACTThe objectives of this research were to know the effect of pasteurized media combined with biologicalagents and the most effective biological agent on heart rot disease. The research was carried out at PT NusantaraTropical Fruit, East Lampung designed by Split Plot Design and repeated three times. The main plot waspasteurized and unpasteurized media. The subplot was control with sterile water or fungicide, Trichodermaharzianum isolated from ginger or banana, Pseudomonas fluorescens P60, and Fusarium equiseti isolated frombanana root. Variables observed were incubation period, disease intensity, late Fusarium conidial population,potentially infected root, crop height, leave numbers, primary or secondary root numbers, root length, and rootweight. Result of the research indicated that the combination treatments gave positively result specially to reducedisease intensity of 43.57%. Biological agents of T. harzianum banana isolate and P. fluorescens P60 combinedwith the pasteurisation could suppress disease intensity of 63.08 and 59.57%, respectively. The most effectivebiocontrol agent was T. harzianum banana isolate because of suppressing Fusarium density, increasing plantheight, and increasing root weight as 41.12, 39.00, and 98.86%, respectively.Key words: heart rot, banana seedlings, pasteurization, biological agents

Abstract

The research objective was to know ability of antagonistic microbes to control bacterial wilt on potato in the field. This research was carried out at Serang Village, Karangreja Subdistrict, Purbalingga Regency from June up to August 2012. The antagonist, originally isolated from potato field, was Bacillus sp. B2 and B4, and Pseudomonas sp. P19 and P20. Based on the research result, Pseudomonas P19 could control the disease on potato with delaying incubation period of 78.95%, suppressing disease intensity of 51.57%, decreasing final pathogenic population of 99.74%, and inducing plant resistance with increasing saponin, tannin, and glycoside content. However, the antagonist could not increase growth and yield of potato.  Keywords: antagonistic microbes, bacterial wilt, potato

Abstract

Background: Shallot cultivation in the rainy season faces the constraints of more severe plant disease problems. Utilization of mixed biopestisda Trichoderma harzianum, Bacillus sp. B8 and Pseudomonas flourescens P8 as well as proper cultivation techniques have not been adopted by farmers. It is necessary to assist farmers in implementing the technology The objectives of the activity are: assisting farmers in implementing the shallot cultivation technology package appropriately, increasing the quantity and quality of crop production, and increasing farmers' income through increasing farm efficiency. Method: The farmers participating in the activity are members of the farmer group "Lestari" Tambak Sogra Village, Sumbang District, Banyumas Regency. Technology transfer method through demplot assistance. The biopesticide technology package and environmental manipulation are compared to the conventional package of synthetic chemical pesticides. Data on the growth and yield of technological plot crops compared to conventional plots. The large number of farmers who can independently apply the technology is observed.  Results: mentoring activities showed that farmer group members were able to independently implement technology packages. The use of biopesticides and proper cultivation techniques can produce growth and yield equivalent to the use of synthetic chemical pesticides. Conclusion: 80% partner farmers can apply technology packages, the use of biopesticides is able to substitute the use of synthetic chemical pesticides, technology packages are able to increase 5.9% of shallot bulbs and reduce 75% production costs.
