Abstract

Rice is the main staple food in Indonesia. The high needs of national rice must be balanced with the high production of rice crops. One of the efforts to increase the production of rice is the application of liquid smoke originated from agricultural waste, namely husk. The research was aimed to determine the effect of the application of husk liquid smoke on rice growth and production. The research used a single-factor randomized block design (RBD) with 5 treatments and 5 replications. The treatments consisted of several concentrations of liquid smoke : 0% (control), 0.5%, 1%, 2%, and 3%. This research employed several stages; land processing, seedling nursery, rice planting, applicating the liquid smoke, fertilizing, maintaining plants, and harvesting. The results showed that the application of husk liquid smoke significantly affected all observational parameters. On the parameters of rice growth and production, the application of 2% liquid smoke showed the best result. The plant height increased by 25.80% and the number of tillers increased by 49.70% compared to the control. The highest increase is in the number of grains per panicle and the weight of 1000 grains was 4,984% and 26.78% respectively.

Abstract

Rice is a staple food source for most of Indonesia's population. The efforts which increase rice production are through plant protection from pests and diseases. The alternative to control pests and diseases used the application of biocontrol agents and liquid smoke. This research aimed to determine the effect of liquid smoke and biocontrol agents in suppressing pest and disease attacks on rice plants. This research used two treatments, liquid smoke and biocontrol agents were applied and conventional ricefield (control with chemical pesticides). Observation parameters included types of pests and diseases found, pest populations found, disease severity, the weight of 1000 grains, and wet weight of grain per hectare. Data were analyzed using a t-test with an accuracy level of 95%. The results showed that biocontrol agents and liquid smoke in rice plants could reduce the population of brown planthopper, suppress bacterial leaf blight, and blast disease, and increase rice yields.

Abstract

It is important to take wise and appropriate actions in responding to the presence of plant-disturbing organisms in cultivated plants, especially rice plants. Farmers often use chemical pesticides to combat pests. They often use these pesticides excessively without regard for the pest to trying control, which may have unfavorable effects such as degrading the quality of the environment and endangering human and animal health. Organic farming practices have recently become more common in the agricultural industry. Organic agricultural goods that only use natural ingredients as fertilizers and insecticides are starting to replace agricultural products that used to use chemical fertilizers and pesticides. Using pesticides carelessly and inappropriately can harm your health, the environment, and the ecological balance. The aim of this research is to find out the types of botanical pesticides and solid organic fertilizers that are effective in controlling rice plant pests and as an effort to increase production. In this research used two variables were used in a factorial randomized block design. Neem leaves, soursop leaves, and papaya leaves are some examples of the many forms of botanical insecticides. Solid organic fertilizer is the second aspect (cow, goat, and chicken manure). The collected findings show that treatment with a mixture of chicken manure and vegetable insecticides from neem leaves showed the best effect in reducing the percentage of pest attacks on rice plants. In addition, it can improve plant development to increase the productivity of rice plants.

Abstract

Biological control by using entomopathogenic bacteria shows potential to be developed as an alternative technique to control Spodoptera litura. Bacteria that can live in extreme environments are reported to have high efficiency and the ability to survive in various environmental conditions, such as in the area of Sidoarjo mud. Related to the issue, this research aimed to find out bacteria that can survive in extreme conditions and are potentially entomopathogenic to control S. litura. The study was conducted from January until July 2021 in the Sidoarjo mud area and laboratory of Biological Control, Faculty of Agriculture, University of Brawijaya. The research was conducted using methods including consist of a sampling of Sidoarjo hot mud, isolation, and screening of bacteria that is potential as entomopathogenic bacteria, bioassay of mortality S. litura, development of larvae and pupal using Completely Randomized Design with 11 treatments and 4 replications, and molecular identification by 16S rRNA. Data for mortality and development of larvae and pupal were submitted to variance analysis, followed in comparison to the averages of the Duncan test at a 5% level of significance. The results showed that 43 colony bacteria from Sidoarjo hot mud have been successfully isolated and obtained 9 isolates selected as entomopathogenic bacteria against S. litura with a percentage of mortality larvae reached 60%. Moreover, bacteria have the potential to inhibit the development of larvae and pupal S. litura. Molecular identification showed that potential isolates are Bacillus subtilis strain 15A-B92, Bacillus thuringiensis strain GTG-29, and Bacillus anthracis strain BA1035.
