AbstractThis research aimed to utilize water used for washing rice as raw material to make high-fiber foods (nata de leri), and to search the optimum sugar levels that can produce the best nata. Laboratory scale experiments were prepared using a factorial design with three repetitions. The treatments tested were four types of rice, such as white rice, brown rice, white and black sticky rice consists of 0, 5, 10, and 15% sugar content. The parameters analyzed were color, thickness, wet weight, fiber content and protein content of nata formed. Observational data were analyzed statistically using analysis of variance with α 1% and 5% followed by DMRT 5% test. Fermentation of various types of rice by the bacterium Acetobacter xylinum took five to seven days. Based on the analysis of variance α 1%, there was significant difference between the type of rice and sugar content to the quality of nata formed. Optimum sugar content that produces the best nata was 5%, which occurs in all types of rice. Excessive sugar in the fermentation medium inhibits the process of medium density allegedly causing bacterial cell lysis. Fermentation derived from white sticky rice produce the thickest and hardest nata, and had the highest fiber content, with values 130 cm, 200 gr, and 75% respectively. This was because the starch content was much in white sticky rice than others. Carbohydrates were used by bacteria as a source of nutrients and energy, which has rich of starch from white sticky rice. While the highest protein content was by nata formed from white rice, which is 1.2%.Keywords: Sugar, Acetobacter xylinum, nata de leriAbstrakPenelitian ini bertujuan memanfaatkan air bekas cucian beras sebagai bahan baku pembuatan makanan berserat tinggi (nata de leri), dan mencari kadar gula optimum yang bisa menghasilkan nata terbaik. Percobaan dilakukan pada skala laboratorium yang disusun menggunakan rancangan faktorial dengan tiga ulangan. Perlakuan yang diuji adalah jenis beras, meliputi beras putih, beras merah, ketan putih dan ketan hitam; serta kadar gula yang terdiri dari 0%, 5%, 10%, dan 15%. Parameter yang dianalisis yakni warna, tebal, berat basah, kadar serat, dan kadar protein nata yang terbentuk. Data pengamatan dianalisis statistik memakai analisis keragaman dengan α 1% dan α 5%, dilanjutkan uji DMRT α 5% bila ada perbedaan yang nyata. Berdasarkan analisis keragaman α 1%, terbukti bahwa ada pengaruh yang sangat signifikan antara jenis beras dan kadar gula dengan kualitas nata de leri yang terbentuk. Kadar gula optimum yang menghasilkan nata terbaik adalah 5% yang terjadi pada semua jenis beras. Gula yang berlebihan dalam medium justru menghambat proses fermentasi karena medium yang pekat menyebabkan sel bakteri lisis. Fermentasi leri yang berasal dari ketan putih menghasilkan nata paling tebal (130 cm), paling berat (200 g) serta mempunyai kadar serat tertinggi (7,5%). Hal ini disebabkan oleh kadar pati dalam leri ketan putih terbanyak dibandingkan dengan lainnya. Kadar protein tertinggi dikandung oleh nata yang dibentuk dari leri beras putih 1,2%.Kata kunci: Leri, gula, Acetobacter xylinum, nata

Late Sowing

The yield, protein and starch content of Martonvásár maize hybrids belonging to different FAO groups were examined in experiments involving early, optimal and late sowing dates in two different years (drought — 2007, favourable water supplies — 2008) on a calcareous chernozem soil with loam texture at the Látókép Experimental Station of the Centre of Agricultural Sciences and Engineering, University of Debrecen.Sowing date had a significant effect on maize grain yield in the dry year. The grain yields of hybrids with longer growing periods were significantly higher than those with shorter growing periods in both years, but they reacted sensitively to the change in sowing date in the dry year. Due to the rainfall distribution in the growing season, sowing date did not modify the performance of the hybrids in the year with favourable water supplies. Sowing date had a significant effect on the grain protein content in the dry year, with significantly higher values after late sowing than after early or optimal sowing. Averaged over the sowing dates, the protein content of the FAO 200 hybrid was significantly higher in both years than that of hybrids in other FAO groups. In the dry year, the greatest difference in protein content could be observed between the early and late sowing dates for hybrids in all four FAO groups. A negative correlation was found between yield and protein content. Sowing date significantly increased the starch content of maize in the favourable year, with a significant difference between early and late sowing dates.In the dry year higher starch contents were recorded for all the hybrids and for all the sowing dates than in the favourable year. In the dry year, sowing date only caused a significant difference in the starch content in the case of FAO 200 sown at optimal and late sowing dates. In the favourable year, a significant difference was only obtained for the starch content of the FAO 400 hybrid sown at early and late sowing dates. Satisfactory quality can only be achieved if suitable genotypes are grown with appropriate technologies.

Npk Fertilizer

AbstractIn recent years, producers of agricultural products have increased the use of chemical fertilizers per unit area. The goal of this research was to analyze the interaction of genotype in treatment (NPK fertilizer) on grain yield, protein content, oil content, and the starch content on 13 maize hybrids using analysis by the model of additive and multiplier effects AMMI and to evaluate genotypes, treatments, and their interactions using biplot in Hungary. Treatments include NPK0 (N: 0 kg/ha, P2O5:0 kg/ha, K2O: 0 kg/ha), NPK1 (N: 30 kg/ha, P2O5: 23 kg/ha, K2O: 27 kg/ha), NPK2 (N: 60 kg/ha, P2O5: 46 kg/ha, K2O: 54 kg/ha), NPK3 (N: 90 kg/ha, P2O5: 69 kg/ha, K2O: 81 kg/ha), NPK4 (N: 120 kg/ha, P2O5: 92 kg/ha, K2O: 108 kg/ha), NPK5 (N: 150 kg/ha, P2O5: 115 kg/ha, K2O: 135 kg/ha) in four replications based on complete randomized block design in 2019. The NPK fertilizer effects indicate that the fertilizers are different on yield genotype. AMMI analysis showed that there was a significant difference between genotypes, treatment, and the interaction effect of genotype * treatment at one percent. Besides, the maximum yield had Loupiac and NPK3 on grain yield, Loupiac and NPK2 on oil content, P0023, and NPK3 for starch content, DKC 3/ES4725 (DKC4725) and NPK3 for protein content. Also, GGE biplot analysis indicates that had maximum grain yield in Loupiac, protein content in P9978, oil content in MV Maronetta, and starch content in Sushi.

Abstract The purpose of this study was to determine the effect of adding beet juice in fermented goat’s milk using Lactobacillus rhamnosus bacteria on the acidity, syneresis value. This study applied a Complete Randomized Design (RAL) consisting of five treatments Control (P0), 2% of beet juice (P1), 4% of beet juice (P2), 6% of beet juice (P3), and 8% of beet juice (P4) with four repetitions. The data obtained were analysed using ANOVA (Analysis of Variance). If a significant difference is found, then Duncan’s multiple range (DMRT) test is conducted. The results showed that the addition of beet juice with a different percentage in fermented goat milk had significant effect (P<0.05) on syneresis but had a very significantly effect (P<0.01) on the pH value. The addition of 2% of Beet juice resulted in the lowest syneresis value of 9.88%. The low value of syneresis in this study was caused by the addition of beet juice which has high acidity, carbohydrate and protein content. The higher the lactic acid, the lower the pH and the denser the texture formed because the protein’s ability to bind water increases so that the syneresis formed is lower.

The thiamine content (by a short method) and the protein content of 754 samples of the 1946 wheat crop and 458 samples of the 1947 wheat crop were determined. In 1946 four varieties were tested m each of the four soil zones, while in 1947 three varieties were tested on the Brown and Dark Brown soils and four on the Black and Black-Gray Transition soils. A highly significant positive correlation between thiamine and protein content was found for the two crops. No significant differences between thiamine values of the Thatcher 1946 and 1947 crop were found. Similarly, an analysis of variance for thiamine content of Redman in the Black and Black-Gray Transition soil zones and Rescue in the Brown and Dark Brown soil zones, for the two crop years showed no significant difference. Of the four varieties, Thatcher, Rescue, Pelissier, and Stewart grown in the Brown and Dark Brown soil zones, Stewart was significantly higher in thiamine content. The greatest range in thiamine content was 2.73 μgm. per gm. for Thatcher in the Black-Gray Transition soil zone (mean 4.01 μgm. per gm.) to 9.57 μgm. per gm. for Stewart in the Brown soil zone (mean 6.18 μgm. per gm.). A highly significant difference was found for varieties grown in different zones for both years. The values decreased as the soil changed from brown to dark brown, to black and degraded black, and finally to gray.
