Abstract

Pemanfaatan tumbuhan refugia lewat rekayasa ekologi ialah bagian dari teknologi pengendalian hama terpadu ( PHT) yang bertujuan pencapaian penyeimbang hayati hama serta musuh natural supaya terletak di dasar ambang ekonomi dan juga meningkatkan keragaman musuh alami sehingga dapat menurunkan serangan OPT pada tanaman cabai merah. Tujuan dari penelitian ini agar dapat menurunkan serangan OPT pada tumbuhan cabai merah, juga untuk mengetahui keragaman musuh alami (parasitoid, predator dan penyerbuk) yang terdapat pada tanaman cabai merah dengan menggunakan tanaman refugia. Metode penelitian ini menggunakan RAK dengan satu faktor yang terdiri dari 5 taraf perlakuan yaitu T0 = Kontrol, T1 = Tanaman Tagetes erecta, T2 = Tanaman matahari mini, T3= tanaman krisan ungu dan T4 = T.erecta + matahari mini + krisan ungu. Hasil penelitian menunjukkan bahwa penggunaan tanaman refugia dapat menurunkan serangan Hama pada tanaman cabai dan meningkatkan musuh alami. Penggunaan tanaman refugia terdapat 8 jenis musuh alami diantaranya terdapat 4 serangga sebagai predator, 1 serangga sebagai parasitoid dan 3 serangga sebagai penyerbuk

Abstract

Currently, the demand for corn in Indonesia is quite large, which is more than 10 million tons of dry shells per year. The largest consumption of corn is for the food and animal feed industry, because as much as 51% of the raw material for animal feed is corn. To increase the amount of production must be influenced by several factors. One of the main factors is the use of appropriate production facilities. Agricultural production facilities are all types of agricultural equipment, equipment and facilities that function as the main or auxiliary tools in the implementation of agricultural production. Production facilities play an important role in achieving production in accordance with the desired goals. The purpose of this study was to analyze the availability of agricultural production facilities in Sunggal District, Deli Serdang Regency. The research area was determined by purposive sampling, namely deliberately based on certain considerations and objectives in Sei Mencharim Village, Sunggal District, Deli Serdang Regency, which is a corn production area. Research from October to December 2021. The results of the multicollinearity assumption test, it can be seen that the means of production of Seeds (X1) has a VIF value of 4.113 which is smaller than 10, Fertilizer (X2) has a VIF value of 1.983 which is smaller than 10, and Pesticides ( X3) has a VIF value of 4.130 which is smaller than 10. The tolerance value of the Seed production facility (X1) has a tolerance value of 0.243 which is greater than 0.1, Fertilizer (X2) has a tolerance value of 0.504 which is greater than 0, 1, and Pesticides (X3) of 0.242 which is greater than 0.1. 2. The average total production costs incurred by corn farmers in one planting season with a land area of 1 ha is Rp 19,440,440, revenue is Rp 35,641,406 and income is Rp 16,200,966. Keywords : production facilities, farming, corn

Abstract

Weeds have strong competitive abilities for CO2, water, sunlight and nutrients. Weeds have a direct effect on the growth and yield of soybean plants. Refugia is an area of weeds that is not disturbing because of its role as a microhabitat that provides shelter spatially and/or temporally for natural enemies of pests, such as predators and parasitoids, as well as supporting components of biotic interactions in ecosystems, such as pollinators or pollinating insects. This research was conducted in a village district level of deli serdang district, using factorial randomized block design (RBD). The results showed that the natural enemies found in soybean plants were mostly from the predator class, and the content of secondary metabolites was known to be saponins and flavanoid compounds, which are compounds found in T.erecta weeds.Keywords: Soybean, Flowering Weeds, Natural Enemies
