Abstract

Indonesia has the potential of natural resources is very high and plentiful. One of them from forest products, both timber forest products and non timber forest products. Bee Trigona spp. is one of the non timber forest resources potential products developed as the price of honey and propolis are high. Cultivation Trigona spp. still a bit of doing at the moment. Around Indigenous Forests of Rumbio ban is one of the locations that have the potential for cultivation Trigona spp. because it has abundant natural resources and nature of the support for the development of the bee. This study aims to determine the prospects for cultivation development Trigona spp. around Forest Prohibition of Indigenous of Rumbio Kampar regency. Materials research is a questionnaire sheet. The data have been analyzed by qualitative analysis. Research showed that the development of cultivation Trigona spp. very suitable to be developed around the Prohibition of Indigenous Forests of Rumbio because climatic conditions in accordance with the development of the bee, the land available for cultivation, as well as the availability of various types of plants produce nectar and pollen as a food source Trigona spp. Key words: Prospects for Development, Indigenous Prohibition Forest, Cultivation Trigona spp.

Abstract

Needs of flour in Indonesia reached 6.6 million tonnes in 2013. To reduce imports of wheat required the development of local food sources, including corn. Corn flour has several drawbacks such as the quality of the nutritional value is still low in comparison to wheat flour. To improve the quality and nutritional value of corn flour then necessary modifications. The manufacture of corn flour using the fermentation process is expected to alter its characteristics so as to extend the application of this starch as food products. This study used a Completely Randomized Design Experiment with 4 treatments and 4 repeats to obtain 16 experimental units. The data obtained were statistically analyzed using Analysis of Variance. If F count is greater than or equal to F table then continued with the test Duncan New Multiple Range Test at the 5% level. The results of this research show that using single and or combination of starters significantly affected all parameters. The best treatment to produce modified corn flour was P3 treatment using Saccharomyces cerevisiae 0,05% + Rhizopus oryzae 0,05% starters with rendement of 75.58%, moisture content 7.60%, pH 3.93, ash 0.43%, swelling power 10.47%, solubility 7.46%, fiber 0.30%, protein 9.84%, fat 3.61%, and carbohydrate contents of 78.51%. Keywords:  Fermentation, Saccharomyces cerevisiae, Rhizopus oryzae, modified corn flour and mocof

Abstract

Jam is semi-solid food made from fruit puree and mixed with 35-45% parts of sugar and heated until the sugar content ranges 50-65%. The study purpose was to get the best ratio of nipa fruit puree and red dragon fruit peel puree in making jam. The research used a Completely Randomized Design Experiment with 5 treatments and 3 replications. The treatments were NM1 (ratio of nipa fruit puree and red dragon fruit peel puree 90% : 10%), NM2 (ratio of nipa fruit puree and red dragon fruit puree 80% : 20%), NM3 (ratio of nipa fruit puree and dragon fruit peel puree 70% : 30%), NM4 (ratio of nipa fruit puree and red dragon fruit peel puree 60% : 40%) and NM5 (ratio of nipa fruit puree and red dragon fruit peel puree 50% : 50%).  The data obtained were analyzed statistically using Analysis of Varience (ANOVA) and Duncan’s New Multiple Range Test (DNMRT) at 5% level. The results show that the ratio of nipa fruit puree and red dragon fruit peel puree significantly affected moisture, ash, crude fiber, total dissolved solid contents and the sensory parameters. The best treatment of jam from this research was NM5 with moisture content 34.92%, ash 0.99%, crude fiber 3.18% and total dissolved solid 70.28% brix. The result of descriptive test jam has red colour (4.33), flavour little nipa fruit and red dragon fruit (3.46), stickiness of sticky jam (3.83) and taste little nipa fruit and dragon fruit (3.40). Overall assessment hedonic test of jam was liked by the panelist (4.02). Keywords: jam, nipa fruit, red dragon fruit peel, puree

Abstract

This study aims to determine the effect of giving organic liquid fertilizer as well as obtaining the appropriate concentration of organic liquid fertilizer in increasing the growth and production of pakcoy plants (Brassica rapa L. The experiment was conducted at Experimental Garden of Agriculture Faculty of Universitas Riau Jalan Bina Widya Km 12,5 Simpang Baru Tampan, Pekanbaru from April to June 2017. The experiment was conducted experimentally using Completely Randomized Design (RAL) consisting of 5 treatments and 4 replications. The treatment given is liquid organic fertilizer (P) consisting of 5 levels, namely: The P0 = Without the application of liquid organic fertilizer (0 cc / l water), P1 = Giving organic liquid fertilizer 2 cc / l water, P2 = Organic fertilizer Liquid 4 cc / l water, P3 = Provision of liquid organic fertilizer 6 cc / l water and P4 = Provision of liquid organic fertilizer 8 cc / l water. Thus obtained 20 units of experiments consisting of 5 tamanan as a sample. The parameters observed were: plant height, leaf number, leaf area, fresh weight of plant and fresh weight of consumption. The data obtained were analyzed using variance then tested further with the Duncan Multiple Range Test at 5% level. The results showed that the application of liquid organic fertilizer significantly affect the parameters of plant height, leaf number, leaf area, fresh weight of pakcoy plant and fresh weight is feasible for consumption. Giving of liquid organic fertilizer 8 cc / L water showed better growth and yield on all parameters of pakcoy plant. Keywords: Pakcoy, organic POC, Growth and production

Abstract

The aim of this study is to observe the interaction between the types of soil and the fertilizer dose of Urea which is for the growth of the seedlings of Robusta coffee (Coffea canephora Pierre). This research has been condected experimentaly of Agriculture Universitas Riau for 4 months since November to March 2017. The research was arrange in a Completely Randomise Design (CRD) with 2 factors. From both factors, it was obtained 9 combination treatments which were repeatedly 3 times. There were 27 treatments in the experiment. Each experiment consisted of 3 seedlings, So it were 81 seedlings and all seedlings were observed. The treatment in this research was the types of soil (Inceptisol, PMK  and Peat) and the fertiliizer dose of Urea (0 g, 5 g and            10 g). The observed parameter was the height of the seedlings, the number of leaves, stem diameter, the area of widest leaf, the root volume, ratio of the root canopy and the dry weight of seedlings. The data was analyzed with Anova and Duncan’s at level 5%. The result showed that there was no interaction effect between the types of soil and the fertilizer dose of Urea on the seedlings of Robusta coffee except for the stem diameter and the root volume. The combination of PMK soil with Urea dose 5 g gave much better growth to seedlings. Types of soil produced the same growth to the 7 month old of Robusta coffee seedlings but it is better on the peat soils.Urea at dose 5 g/seedling gave the best growth for seedlings.

Abstract

The research objective was to determine the effect of cow blood flour fertilizer instead of inorganic fertilizers and get the best dose for growth and production of soybean plants. This research was conducted at the experimental field UPT Faculty of Agriculture, University of Riau. The study took place in July until October 2015, research conducted experiments using completely randomized design (CRD) comprised of 5 treatments and 4 replications. Such treatment is the administration of cow blood flour consisting of K0 (cattle blood flour 0 kg / ha); K1 (cattle blood Flour 200 kg / ha); K2 (cattle blood Flour 400 kg / ha); K3 (cattle blood Flour 600 kg / ha); K4 (cattle blood Flour 800 kg / ha). The parameters observed  were plant height, number of primary branches, plant dry weight, flowering plant age, seed weight per plant, weight of 100 seeds and harvest index. Data were statistically analyzed using analysis of variance and  Duncan's multiple range test at 5% level. The results showed that cattle blood flour can be used as a substitute for inorganic fertilizer, where the provision of cattle blood flour as much as 400 kg of urea is equivalent to giving as much as 50.8 kg. Implementation of cow blood flour as much as 600 kg / ha and 800 kg / ha dose was better for the growth and yield of soybean Wilis variety. Keywords: cattle blood flour, growth, production, soybean
