Aplikasi Biochar Cangkang Kernel Kelapa Sawit dan Limbah Baglog Jamur Terhadap Pertumbuhan dan Produksi Padi Beras Merah pada Pertanaman Karet

Abstract

The Application of Biochar Palm Kernel Shell and Mushroom Baglog Waste to The Growth and Production Of Brown Rice in Rubber Plantation, under the guidance of Dr. Ir. Sumihar Hutapea, M.S. as the chairman of the mentor and Ir. Ellen L. Panggabean, M.P. as the member of the mentor. This research was aiming to find out whether the application of biochar palm kernel shell and mushroom baglog waste has a positive influence on the growth and the production of brown rice. This research was held in Dusun Pondok Rowo Desa Sampali, Subdistrict Percut Sei Tuan District Deli Serdang Province Sumatera Utara. The type of the soil was alluvial with the height was 20 above the sea level and the soil pH was 6,5. The research was held on June to October 2018. This research was held by using the Factorial Randomized Group Design (RAK) with 2 treatment factors. The first factor was the biochar of the palm kernel shell which consist 4 dose stage, that are B0 = without the biochar of the palm kernel shell (control), B1 = 0,5 kg of biochar of the palm kernel shell / plot, B2 = 1 kg of the biochar of palm kernel shell / plot, B3 = 1,5 kg of biochar of the palm kernel shell / plot. The second factor was the mushroom baglog waste which consist 4 dose stage, that are T0 = without the mushroom baglog waste (control), T1 = 2 ton/ha of mushroom baglog waste : 200 gram/plot, T2 = 4 ton/ha of mushroom baglog waste : 400/plot, T3 = 6 ton/ha of mushroom baglog waste : 600 gram/plot. The result of this research showed that the treatment of giving biochar to brown rice in rubber plantation had a real effect on the growth of the plant height in the age of 6 MSPT and the weight of production of sample crop and didn’t have a real effect on the production weight per plot, number of tillers, number of panicles of sample crop and the amount of 1000 grains of brown rice. The treatment of giving oyster mushroom baglog tp brown rice in rubber plantation had a real effect on the production of the rice per plot, and the production weight of sample crop and didn’t have a real effect on the growth of the number of the tillers, number of panicles of sample crops, and amount of 1000 grains of brown rice. The combination of both factors didn’t have a real effect on the growth and the production of brown rice.
