Abstract

The demand for chili peppers in Indonesia continues to increase, but in 2021 there was a decrease in chili production. One of the main causes is pathogen attack, especially Ralstonia solanacearum which causes bacterial wilt disease in chili plants. This study aims to evaluate the potential of Streptomyces sp. isolates BMP and TMP to reduce the virulence of R. solanacearum. The research was conducted through a series of laboratory experiments, including an inhibition test with double-layer method and virulence reduction test on Triphenyl Tetrazolium Chloride (TZC) media. The results showed that the TMP isolate was able to produce an inhibition zone of 1.5 cm2 while the BMP isolate showed no inhibition zone. In addition, this study also evaluated the virulence reduction of R. solanacearum due to the treatment of Streptomyces spp. The virulence reduction test showed that TMP isolates were able to reduce virulence by 70% while BMP isolates were able to reduce the virulence of R. solanacearum by 4%. These findings provide new insights into the development of R. solanacearum control strategies. In conclusion, isolates of Streptomyces sp. especially BMP showed potential in reducing the virulence of R. solanacearum, thus providing new hope in efforts to increase chili production sustainably.

Abstract

Acid sulfate soil is a type of suboptimal wetland that has problems including high acidity, low nutrients, and high solubility of Al and Fe. These problems are often overcome by the use of lime and chemical fertilizers, but if we look closely, the unwise use of chemical fertilizers can have a negative impact on the land. The organic farming system through the System of Rice Intensification (SRI) can be an alternative solution for the development of rice cultivation in acid sulfate soils. Therefore, the application of organic matter in the form of compost from agricultural waste (rice straw, coffee grounds, and oyster mushroom baglog waste) is believed to be able to increase the growth and production of rice in acid sulfate soils. The purpose of this study was to determine the potential impact of agricultural waste compost on the growth and production of rice using the SRI method in acid sulfate soils. This research was carried out for six months, from March to September 2021, in Sungai Rangas Village, Martapura Barat District, Banjar Regency, South Kalimantan Province. This research method used a randomized block design (RBD) with 1 factor, namely the type of compost: a0 = without compost application, a1 = rice straw compost, a2 = coffee grounds compost, and a3 = oyster mushroom baglog waste compost. Each treatment consisted of five blocks, so there were 20 experimental units. The results showed that the application of agricultural waste compost has the potential to increase the growth and production of rice using the SRI method on acid sulfate soils. Rice straw compost (a1), coffee grounds compost (a2), and oyster mushroom baglog compost (a3) were able to increase plant height, number of productive tillers, weight of 1,000 grains of rice, and harvested dry grain weight compared to control (a0).

Abstract

Bacterial wilt disease is a serious threat to cayenne pepper plants because it can cause a significant reduction in production. Although Bacillus sp. has been applied using liquid formulations, the results have not been optimal. Therefore, bioencapsulated formulations in the form of Beads have been tested as an alternative to increase their effectiveness. These Beads were made using sodium alginate cross-linked with CaCl2 through an extrusion technique. The application of Beads with the K2W1 treatment combination showed the lowest disease intensity level, which was 55.5%, and the effectiveness of inhibition reached 44.5%. From the results of this study, it can be concluded that the beads formulation is significantly potentian in inhibiting bacterial wilt disease on chili plant
