Abstract

Cabai merah (Capsicum annuum L.) memiliki permintaan dan peluang pasar yang tinggi, namun produktivitasnya tidak stabil akibat suhu lingkungan yang tidak optimal sehingga pembentukan bunga menjadi buah rendah. Naungan dapat menurunkan suhu lingkungan dan triakontanol dapat memicu pembentukan bunga dan buah sehingga mengurangi bunga dan buah yang gugur. Penelitian dilakukan untuk mengkaji pengaruh naungan dan triakontanol terhadap pertumbuhan dan produktivitas tanaman cabai merah besar. Penelitian dilakukan di Desa Jetis Karangpung, Kalijambe, Sragen, Laboratorium Fisiologi dan Pemuliaan Tanaman, serta Laboratorium Ekologi dan Produksi Tanaman, Fakultas Peternakan dan Pertanian, Universitas Diponegoro, Semarang pada bulan Maret – Juli 2022. Penelitian menggunakan Rancangan Petak Terbagi (Split Plot) pada Rancangan Acak Kelompok (RAK), terdiri dari 4 petak utama dan 4 anak petak dengan 3 ulangan. Petak utama berupa intensitas naungan (N) (0%, 15%, 30%, 45%). Anak petak berupa konsentrasi triakontanol (T) (0 ppm, 2,5 ppm, 5 ppm, 7,5 ppm). Hasil menunjukkan bahwa tinggi tanaman, luas daun, kadar klorofil, berat segar dan kering tajuk, jumlah bunga dan buah, serta berat buah berpengaruh terhadap pemberian naungan dan triakontanol. Jumlah daun dan persentase bunga menjadi buah hanya berpengaruh terhadap pemberian triakontanol dan umur berbunga hanya berpengaruh terhadap pemberian naungan. Berdasarkan hasil penelitian dapat disimpulkan bahwa pemberian naungan 45% dan triakontanol 7,5 ppm menghasilkan pertumbuhan dan produktivitas terbaik pada tanaman cabai merah besar.

Abstract

[EFFECT OF CONCENTRATION AND TIME INTERVAL OF BABANDOTAN BIOPESTICIDE SPRAYING ON THE INTENSITY OF DAMAGE AND YIELD OF KAILAN]. Biopesticides from Ageratum conyzoides plants are used as an alternative in pest control. The used of synthetic pesticides was widespread as an effort in pest and disease control because it worked effectively and quickly, but caused resistance and resurgence of pests were bad impact on the environment for long term. The content of active compounds in Ageratum conyzoides plants such as flavonoids, anthraquinone, tannins, terpenes, phenols, saponins, alkaloids and steroids worked as controllers of various cultivated plant pests. This study aims to determine the spraying concentration and interval of spraying Ageratum conyzoides on the intensity of damage and yield of kailan plants. This research was conducted in November 2020 - January 2021 at Agroecotechnopark research land, Diponegoro University, Semarang. The experimental design used was a factorial Randomized Complete Block Design with 3 replications. The first factor was spraying concentration (10%, 30% and 50%) and the second factor was interval of spraying (once every 5 days, 10 days and 15 days). The variables observed were absolute damage rate, relative damage rate, plant height, number of leaves and fresh weight of kailan. Data were analyzed by Analysis of Variance followed by DMRT (Duncan's Multiple Range Test). The results showed that Ageratum conyzoides biopesticide was able to control pests and and to support kailan growth. Spraying babandotan biopesticide at a concentration of 50% has been able to reduce the rate of crop damage by pests, supported vegetative growth, and increased kailan growth to provide optimal yield. Spraying time interval did not affect all variables.
