Penetapan Kadar Amilosa Dan Protein Pada Beras Solok Jenis Anak Daro Dan Sokan Yang Ditanam Dengan Sistem Pertanian Organik Dan Sistem Pertanian Konvensional

Abstract

The organic farming system is a holistic agricultural production management system for improving and developing agro-ecosystem health, including biodiversity, biological cycles, and soil biological activities. Organic farming systems use natural fertilizers and pesticides, while conventional farming systems still use chemical fertilizers and pesticides. Environmental conditions are expected to affect the chemical content of rice. One of the main chemical constituents in rice is amylose and protein. This research is a laboratory experimental study that aims to see the amylose and protein content of Solok rice types sokan and anak daro which grown with organic farming system and conventional farming system. From the result of the research, equation of calibration curve amylose is Y = 0,0246X + 0,0146 with correlation coefficient (r) = 0,9984. Amylose content of Solok rice type of anak daro organic 28,90%, anak daro conventional 28,04%, sokan organic 30,32% and sokan conventional 30,94%. Protein content of Solok rice type of anak daro organic 8,79%, anak daro conventional 8,15%, sokan organic 8,50% and sokan conventional 8,25%. T value of each group is smaller than the T table value, it can be concluded that the result is not significantly different.

Comparison Effect of Cisokan Rice Flour and Cornstarch on Quality Characteristics of Snack Foods Extrudate with Protein Sources of Bilih Fish (Mystacoleucus padangensis)

“…It is proven that each treatment has the same water formulation. Then this opinion is also supported by Lestari et al [15], who that the improvement in the texture of food products is determined by the amount of protein content in these food products due to the long peptide bonds that are not easy to break these bonds and produce a hard texture.…”

“…Rice has a starch content of 79%, with a small amount of aleurone and an amylose content of around 20%. According to research by Lestari et al, [15], the amylose content of Solok rice for the organic Sokan type was 30.32% and 30.94% for conventional rice. While corn contains 72-73% starch with amylose: amylopectin ratio ranging from 25-30%: 70-75%, even in glutinous corn (waxy corn) has amylopectin levels reaching 100% [16].…”

Analysis and Identification of Chemical Content of Rice of Several Strains Local Upland Rice

“…This caused the 15 strains studied to show no significant effect on the protein content of rice. The results of research by Lestari et al, 2018 suggested that the protein content of Solok rice was 8.79% organic, 8.15% conventional, 8.50% organic, and 8.25% conventional. 8.50%, and conventional sokan 8.25%.…”

Rice Quality and Yield at Various Application Times of Organic Rice Management System

“…Analysis of protein levels was performed using the Kjeldhal method based on guidance from Balai Penelitian Tanah (2009), with a conversion factor of 5,95. Determination of amylopectin levels was determined using the Iodo colorimetric method calculated using the standard amylose-amylopectin curve with a wavelength of 625 nm (Lestari et al 2018). The reduced sugar content in rice was analyzed using the -Somogyi method with the addition of nelson and arsenomolybdate reagents and the determination of the standard glucose curve with a wavelength of 540 nm (BeMiller 2018).…”
