Abstract

Vegetables from the Solanaceae family have become a commodity that is popular with the public, however the production of these vegetables often declines due to pest attacks. Control that has a big impact on the ecosystem around the land. However, farmers still very rarely carry out integrated pest control. This research is to achieve the level of implementation of integrated pest and disease control carried out by Solanaceae plant farmers in South Sumatra. The research was conducted by surveying several Solanaceae plantations in Ogan Ilir, Banyuasin, Ogan Komering Ulu, Muara Enim, and Palembang City. The research method used was purposive sampling, which determined plant samples from each field. The research results showed that the level of IPM implementation by farmers reached a score of 61%. Although farmers generally use pesticides as the main alternative. So, farmers' application of IPM has an effect on pest and disease attacks. IPM scores affect 3% of the pest population and 46% of the percentage of disease attacks. The implementation of IPM by farmers is sufficient, so only small improvements need to be made.

Abstract

Weeds always appear in minimal or intensive tillage and cause less optimal growth of cucumbers. This study aims to determine the effect of arthropod diversity on the surface of cucumber plants with weed and non-weed land treatments. The research was conducted in the village of Ujanmas Baru, Muara Enim Regency, South Sumatra. Arthropod observations were carried out using 3 visual methods, pantrap and pitfall traps and the results were analyzed using the calculation of Diversity Index (H'), Individual Distribution (E') and Dominance Index (C). The index obtained in the pitfall traps of the study area with no weeds and weeds in the vegetative and generative phases was categorized in the medium category (H'= 0.56-1.27). The dominant index value of soil arthropods in pitfall traps treated on non-weeds and weeds in the vegetative and generative phases was categorized in the high category range (D = 0.35-0.82). However, in this study the species caught in pan traps were treated on non-weed land and weed land with a diversity index (H') categorized as moderate and a dominant index value (D) categorized as low. The conclusion of this study was that the species of arthropods found in cucumber plants treated with weeds and no weeds did not significantly affect the diversity of arthropods on the cucumber soil surface. Arthropod diversity in cucumber plants in both treatments with pitfall traps and pantrap included in the moderate category with the highest diversity index values of 1.27 and 2.19. Arthropod insect pests found on the surface of the cucumber planting soil consisted of 4 orders and 8 families dominated by Collembola sp and Acheta sp.

Abstract

Indonesia is a country that depends on the agricultural sector. During the Covid 19 pandemic when all sectors experienced a decline, the agricultural sector continued to record positive growth. Therefore, the Madiun City Food Security and Agriculture Service, in order to restore the economy, initiated the Sustainable Food Yard program in the form of using yards to grow vegetables which can be sold to increase household income. In 2023, funding from DKPP will stop so that P2L begins to face risk uncertainty. Risk is an uncertain situation that can hinder the achievement of goals. Therefore, risks need to be identified so that they can be handled so as not to cause major losses. The method used to identify risks is the fishbone diagram. The results of this research are that there are thirty risks that occur in the vegetable business at P2L Ngongak Tanduran. This risk is divided into five variables, namely six risks in the money variable, eight risks in the material variable, six risks in the man/personnel variable, five risks in the methods variable, and five risks in the machines variable.

Abstract

Soybean (Glycine max (L) Merrill) is one of the food crop commodities in Indonesia. Soybean crop productivity decreased due to one of them being attack of B. tabaci Genn. One of the ways for controlling B. tabaci Genn. pests in soybean cultivation is by using a barrier. Barrier is an integrated pest management (IPM) which is based on ecological balance in nature. Pests are prevented from coming and attacking crops by using various forms of barriers that can slow down the movement of pests. The use of barriers can be a useful tool to reduce the development of B. tabaci Genn. on planting. This study was conducted to determine the effect of using a barrier on the population and attack of B. tabaci Genn. The barriers used in this study are plastic barriers, organdy barriers, sunflower barriers, and corn plant barriers. The study used a randomized block design with 5 treatments, namely P1 = control, P2 = organdy barrier, P3 = sunflower barrier, P4 = corn plant barrier and P5 = plastic barrier. The data obtained were then analyzed using ANOVA variance and further tested using the DMRT test at 5% level. The observed variables were population and attack intensity on B. tabaci Genn. in soybean planting areas, visits by other pests and soybean yields.

Abstract

Cosmos sulphureus and Tagetes erecta are habitats for insects because they are able to provide the food needed by insects in the form of nectar, while the aromatic plants Apium graveolens and Ocimum bassilicum contain essential oils which act as pest repellents. Therefore, these plants can be used as a method of pest control by intercropping with the main crop. This study aims to determine the extent to which the influence of aromatic and flowering plants in controlling Thrips sp. on red chilies. The research was carried out using a randomized block design (RBD) method with one factor studied, namely the effect of aromatic and flowering plants on Thrips sp. pest control on red chili plants and the treatment combination consisted of, P0 = control (Capsicum annum L. without treatment), P1 = (Capsicum annum L. + Apium graveolens), P2 = (Capsicum annum L. + Ocimum bassilicum), P3 = (Capsicum annum L. + Cosmos sulphureus), P4 = (Capsicum annum L. + Tagetes erecta). Analysis of the research data used variance (ANOVA) and if there was a significant difference it was further tested using the LSD (Lessest Significant Difference) level of 5%. The results of this study indicate that the treatment of aromatic Apium graveolens, Ocimum bassilicum, Cosmos sulphurous and Tagetes erecta flowering plants is quite effective in controlling population numbers of Thrips sp. and intensity of attack by Thrips sp. on red chili plants.
