Produksi Benih Kentang Secara Aeroponik Dengan Root Zone Cooling Di Dataran Rendah Tropika Basah Dan Aplikasi Biopestisida

Abstract

Aeroponic technology for wet tropical lowlands have been developed with the application root zone cooling (RZT). High temperatures in the lowlands trigger the disease. Biopesticides have been tested for red onions, tomatoes, peanuts and chili in Banyumas, but it is not known what effect, if applied to the aeroponic system with RZT in the lowlands. The research objective is to get the concentration biopestida for growth and the best results of the varieties grown in aeroponics to RZT in wet tropical lowlands. Factors to be tested: box aeroponic without RZT and biopesticides 1ml / liter (B1), box aeroponics RZT 10 °C biopesticides 4 ml / liter (B2), box aeroponics RZT 10 °C without biopesticides (B3), aeroponics box RZT 10 °C biopesticides 10 ml / liter (B4). The varieties of seed potatoes: Alantic varieties (V1), Variety Granola (V2). The study used a completely randomized design (CRD) and repeated 4 times. Analysis of data using analysis of variance followed by DMRT at the level of α = 5%. Results showed that the varieties of granola in aeroponic systemwith RZT and application of biopesticides 4 ml/ liter and 10 ml/ liter gave the highest plant height.Biopesticides 10 ml / liter on average produces the highest number of leaves, and biopesticides 4 ml / liter produces the highest number of tubers.

Dampak Kenaikan Harga Pupuk terhadap Penggunaannya pada Usahatani Cabai Keriting di Kota Pekanbaru

“…Dolomit harus digunakan pada tanah dengan pH rendah untuk menetralkan pH tanah. Kemampuan akar untuk menyerap unsur hara bergantung pada PH tanah (Sumartono dan Sumarni, 2013). pH ideal untuk tanaman cabe adalah antara 5,5 dan 6,8. pH yang lebih tinggi dari 7,0 menyebabkan gejala klorosis, yaitu kekurangan zat besi (Fe), dan pH yang lebih rendah dari 5,5 menyebabkan kekurangan magnesium, fosfor, atau kalsium pada tanaman cabai ( BPTP Riau, 2017).…”

Strategi Pengembangan Usahatani Perbenihan Kentang di Kabupaten Kerinci

“…Upaya ini dapat dilakukan dengan beberapa teknologi yang tersedia seperti teknologi produksi umbi mikro (Hidayat, 2011), aeroponik (Gunawan and Farrizal, 2009;Dianawati et al, 2013;Sumarni et al, 2016) dan kultur jaringan (Karjadi, 2016).…”

Evaluation of the Coolnet Placement Distance to Direct Evaporative Cooling to Increase Potato Seed Production in Aeroponic Systems with Root Zone Cooling in the Lowlands

“…Cooling to reduce high air temperatures on the surface of potato plants in the tropical lowlands has been carried out through evaporative cooling methods, the application of nutrients, and the application of root zone cooling (Sumarni et al, 2021b;. The air temperature that can be reduced from the application of direct evaporative cooling is up to 7 -9.5 C (depending on air conditions, water spray, and flow direction).…”

“…The results of previous studies stated that direct evaporative cooling has lower energy consumption when the temperature drops to 26 °C, which is 389 kJ, while cooling using an air conditioner (AC) is 902 kJ (Yunianto, 2018). The use of a coolnet in direct evaporative cooling has been carried out and can reduce the air temperature in the greenhouse (Sumarni et al, 2021b). Coolnet delivers uniform micro -sized droplets (65 microns), thereby preventing crop damage.…”
