Abstract

Cow Urine Liquid Compost is a waste nitrogen-containing compounds, water, minerals, hormone auxin and other metabolic products that are useful for plant growth. Giving liquid compost into the soil of cow urine is beneficial to improve soil structure and add the availability of nutrients in the soil. This research aims to determine the interaction of liquid composting of cow urine and NPK fertilizer on peanut crop production as well as to get the best dosage. This research was conducted at the Faculty of Agriculture, University of Riau from November 2016 until January 2017 using a randomized block design which consist of two factors and three replications, where: Factor I (dosing cow urine liquid compost) that is: without giving cow urine liquid compost, concentration of 20% with a dose of 1:38 l per plot, concentration of 30% with a dose of 1:38 l per plot and a concentration of 40% with a dose of 1:38 l per plot. Factor II (NPK), that is: without dosing NPK, 27 g per plot, 54 g per plot and 81 g per plot. Interaction of cow urine liquid compost and NPK showed a significant effect on number of primary branches and production per plot of peanut. The highest production of peanut crop obtained by giving cow urine liquid compost at concentration of 40% and NPK 81 and 54 g per plot with a yield that is 1291,8 - 1272.0 g per plot. Keywords: liquid compost, cow urine, NPK and peanuts

Abstract

Water availability is a major factor limiting the production rate of oil palm plantations. Availability of water for palm oil plants in the field is obtained from rainfall. The research was conducted at PT. Perkebunan Nusantara V Tandun Estate, Riau Province, for three months starting in June until August 2016. This study uses secondary data available on the administration of the garden. Secondary data for analysis include TBS monthly production data for 5 years (2011-2015), the data age of the plant 5, 10 and 20 years after planting, rainfall data and rainy day for 9 years (2007-2009). The analytical method used is analasis multiple linear regression and correlation models tested for feasibility with the classical assumption test including normality test, heteroscedasticity test and multicollinearity test. Regression analysis showed that variable rainfall and rainy days significantly affected on alpha 1% (Sig <α 0,01) to FFB production at the age of 5 years. Results F-count of 29.07 with a significance value of 0.00. The coefficient of determination (R2) obtained 63.8%. This means that 63.8% of FFB production variations can be explained by the variation of the variables used and the remaining 36,2% is explained by the other variables not incorporated into the model. Regression analysis equation on a 5-year-old plant was Y = 414633.827 + 2530.523 X1 - X2 21848,726. Results of correlation analysis at 5 years old plants showed variable rainfall and rainy days have a very strong relationship. Correlation value of rainfall and rainy days and 0.720 - 0.543.Keywords: rainfall, raining, FFB production.

Abstract

Instant drink is a processed food product in powder form, easily soluble in water, practical in its presentation, and has a large surface area. The purpose of this study was to obtain the right combination of fruit and lemon meat combinations so as to produce instant drinks that meet SNI 01-4320.1996 and get consumers. The treatment in this study is P1 = nutmeg extract: lemon fruit extract (90:10), P2 = nutmeg extract: lemon fruit extract (80:20), P2 = nutmeg extract:lemon extract (80:20), P3 = nutmeg extract: lemon fruit extract (70:30), and P4 = nutmeg bark extract: lemon fruit extract (60:40). The parameters observed were water, ash , total sugar, antioxidant activity test and sensory test of aroma, color, taste, texture and overall assessment. The data obtained were statistically tested using variance. If F count is greater or equal to F table, the analysis will continue with the DNMRT test at the level of 5%. The results of variance showed that variations in the addition of lemon extract had a significant effect on water, ash, total sugar , antioxidant and descriptive sensory assessments on color parameters, aroma fineness and overall hedonic taste. The best research results of instant powder in treatment P4 (60% nutmeg bark extract ratio: 40% lemon red extract) with a moisture  of 1.72%, ash 1.29%, sugar  33.67% antioxidant 111.84 ppm, has lemon flavour, tastes lemon, and has a smooth texture and is light brown to slightly yellow in color, and overall favored by panelists. Keywords :instant powder, nutmeg, lemons
