Abstract

Cayenne pepper (Capsicum frutescens L.) is a horticultural crop in Indonesia that often has many obstacles. The main obstacle that is often faced is wilt disease caused by the fungus Fusarium oxysporum. Bacillus spp. bacteria have the potential to control the fungus F. oxysporum. The purpose of this study was to determine the ability of Bacillus spp. bacteria in controlling fusarium wilt disease. This research was conducted from August to November 2023 at the Plant Health Laboratory and screen house of the Faculty of Agriculture, National Development University "Veteran" East Java. The study used a Factorial Complete Randomized Block Design with three replications and nine treatments so that there were 27 experimental units. The observation variables included incubation period, disease intensity, plant height, number of leaves, first flower appearance and fruit wet weight. The research data were analyzed using ANOVA analysis of variance procedure to determine whether there is an effect of each treatment. If it is known that there is a significantly different effect from the treatment, it will be continued with the DMRT test at the 5% level. The results showed that the combination of Bacillus spp bacteria and dosage had an effect on the incubation period and disease intensity. The results showed that the combination of Bacillus spp bacteria and doses had an effect on vegetative phase parameters, namely plant height and number of leaves. However, the combination of Bacillus spp and dosage showed that the generative phase parameters did not significantly affect the first flower appearance and fruit wet weight

Abstract

Shallots (Allium ascalonicum) are a commodity in Indonesia that has high economic value. One of the pests that often attacks and reduces shallot yields is the onion caterpillar pest S. exigua. Tobacco plants and babadotan weeds are types of plants that can be used as botanical pesticides as a method of controlling and preventing pest attacks on plants. Tobacco and babadotan plants contain secondary metabolite compounds such as alkaloids, flavonoids, saponins, terpenoids and tannins which are able to kill insect pests on shallot plants. The aim of this research is to determine the effectiveness of tobacco extract (Nicotiana tabacum L.) and Babadotan (Ageratum conyzoides L.) as control of the onion caterpillar pest Spodoptera exigua on shallots. The highest combined mortality rate was treated with T6 at 96JSP with an average of 75%,The lowest larval mortality percentage test was found in T2 with an average mortality result of 22.50%.The results of biosafety testing show that the combination of tobacco extract and babadotan extract cannot be used together. From the conclusions that have been obtained, the extracts of (Nicotiana tabacum L.) and (Ageratum conyzoides L.), both single extracts and combination extracts, are effective in controlling the pest S.exigua

Abstract

Understanding biological concepts is the main target of learning because it relates to the Sustainable Development Goals (SDGs) objectives. However, understanding biological concepts still needs to be solved in Indonesia, one of which is the low understanding of biological concepts in ecosystem material. The purpose of this study is to ascertain how students' comprehension of concepts in ecosystem material is impacted by the Socio Scientific Inquiry (SSI) learning approach. A quasi-experiment with a two-group pre-test-post-test design was used in the research methodology. The sampling technique used was cluster random sampling. The research instrument was an essay with ten concept understanding questions in it. To find the standard deviation, mean, median, and mode of the data, descriptive analysis was employed as the data analysis approach. The independent t-test was used to assess the study's hypothesis, and the normality and homogeneity tests were run for the precondition analysis. The findings of the descriptive analysis show that the average post-test score in the experimental class is 80.50, whereas it is 67.83 in the control class. This discrepancy suggests that the experimental class's average post-test score is higher than that of the control group. T-test result found that the Sig (2-tailed) value was 0.000 < 0.05, which resulted in the acceptance of Ha and the rejection of H0. This suggests that students' conceptual comprehension is impacted by the Socio Scientific Inquiry (SSI) learning model. This study concludes that the Socio Scientific Inquiry (SSI) learning paradigm improves students' conceptual comprehension when compared to standard learning paradigms.
