Abstract

Cultivation of Strawberries (Fragaria Sp) in substrates Hydroponics can use Liquid Organic Fertilizer (LOF) Super Bionics as a source of nutrients, which need to be investigated the accuracy of the concentration of application, with the aim of getting the best concentration for the growth and production of strawberris. Research was conducted experimentally using completely randomized design (CRD) with 6 treatments and 4 replicates ie liquid organic fertilizer Super Bionic with a concentration of 0 ml / l of water, 1.5 ml / l of water, 2 ml / l of water, 2.5 ml / l of water, 3 ml / l of water and 3.5 ml / l of water. Parameters observaced  such plant height (cm), number of leaves (leaf), days to flowering (days), the age of first harvest (days) and the weight of fruit  per plant (g). The results showed that the liquid organic fertilizer Super Bionic 3 ml / l of water provide the best results on all parameters observed such plant height, leaf number, date of flowering, the age of first harvest and  weight of fruit  per plant.    Keywords: Strawberries (Fragaria Sp), Super Bionic liquid organic fertilizer, substrates       hydroponics.

Abstract

Ice cream is a semi-solid food made by freezing a mixture of milk, fats of animal and vegetable, sugar, and other foodstuffs. This study aims to get the best ratio between full cream milk and red palm oil. This research used a Complete Randomized Design (CRD) with four treatments and four replications. The treatment were ratio of full cream milk : red palm oil 100:0 (E0), 97:3 (E1), 94:6 (E2), 91:9 (E3). The data were statisticallyanalyzed using Analysis of Variance (ANOVA) and Duncan's New Multiple Range Test (DNMRT) at 5%. The research observed was overrun, melting rate, total solids, protein content, fat content, and sensory test. The best treatment of ice cream from this research was E2 which have overrun 23.45%, melting rate 12.47 minutes, total solids 33.01%, fat 5.17%, and protein 2.82%.The result of ice cream’s descriptive assesment testwere  yellow colour (2.83), taste sweet (2.50), slightly flavour red palm oil (3.33), and texture creamy (2.26). Overall assessment hedonic  test of ice cream was preferred by the panelists. Keywords : Ice cream, full cream milk, red palm oil

Abstract

As the raw material of making papers, the need for wood always increases in everyday lives. There is one alternative to overcome that case; it is by advancing woods plants industry (HTI). Accacia crassicarpa is a kind of plant grown for HTI, hence it is necessary for providing a high quality of Accacia crassicarpa seeds and adding some vegetative plants by cutting a tip of leaf. For increasing the productivity, 100% of cocopeat media is used. This research used 100% of ex cocopeat. The problem raised is that the cocopeat media in PCN used only once in nursery so that it becomes a compost heap. Furthermore, in this research ex cocopeat is used as the alternative to fulfill the need for seedling media in PCN, hence the improvement of the quality of ex cocopeat with some tested treatment scientifically is so much required. The aim of this research is to find out the effects of using ex cocopeat as recycle media toward the growth of leaf cutting and determine the finest treatment for seeds growing of Acacia crassicarpa. The research method arranged in complete random program (RAL). The result revealed that using ex cocopeat media with the frying treatment can increase the growth of leaf cutting of Acacia crassicarpa. Fried ex cocopeat media and added with some dolomite are able to show the growth of leaf cutting of the finest Acacia crassicarpa with the living percent (86.66%), bud height (5.52%) and the diameter of leaf cutting (1.37). Keywords : Ex Cocopeat Media, Leaf Cutting, Acacia crassicarpa

Abstract

The research aimed to determine the effect of fertilizer on crops and sweet corn crops on the provision of Guano fertilizer with NPK, and get the best dose of the treatment in peatland. The experiment was conducted in an experiment consisting of 5 treatments using a randomized block design. Each treatment has been repeated 4 times, so that 20 units of experiment are obtained. Each experimental unit consisted of 32 plants, 5 plants sampled. Individual treatment without fertilizer, guano fertilizer 6 Ton/ha + NPK 150 kg/ha, guano 6 Ton/ha + NPK 300 kg/ha, guano 12 Ton/ha + NPK 150 kg/ha, guano 12 Ton/ha + NPK 300 kg/ha. The data obtained were analyzed statistically and continued by using multiple Duncan multiple assay at 5% parameters observed were plant height, harvest age, tuna length, cob hemeters, cob weight with weight per plant, cob weight without weight per plant, Seeds per ear, cob production with per 6m2 weight, and unsweetened cob production per 6m2 of sweet corn. The result data showed better production of sweet corn plant obtained by Guano 12 Ton/ha with NPK 300 kg/ha.Keywords: Sweet Corn, Peat Land, Guano Fertilizer with NPK

Abstract

This study aims to determine the effect of liquid organic fertilizer application of banana fruit peel and get the best dose for the growth of areca seedlings. This research was conducted at experiment station of agriculture faculty of University of Riau from July to November 2017. This research was conducted in the form of experiment using completely non-factorial randomized designconsisting of 5 levels and 4 replications. The liquid organic fertilizer of banana fruit peel consists of 0, 250, 500, 750, 1000 ml.10 kg-1 medium. Data have been statistically analyzed and examined further with using the duncan's new multiple range test (DNMRT) at 5% level. The results showed that increased dosage of liquid organic fertilizer banana fruit peel increased the accretion height of seedlings, dry weight and shoot root ratio, but no increase the leaf number accretion, stem circumference and widest leaf area.The dosage of liquid organic fertilizer of banana fruit peel of 750 ml.10 kg-1 medium gives the increase of accretion height seedlings, dry weight and the highest shoot root ratio in 6 month old areca seedlings.Keyword : Seedlings, liquid organic fertilizer of banana fruit peel, growth

Abstract

Bintaro plants grow naturally in Sumatera swamplands, yet people have not utilized this plant because of the lack of knowledge. Bintaro seeds have high oil content which makes it potential as a source of vegetable oil and can be developed as fuel too. The purpose of this research is to know the effect of different maturity level and treatment on the quality of bintaro seed oil content using soxhlet method with n-hexane solvent and also to determine the treatment process to obtain the best quality of bintaro seed oil. The research was conducted in Agricultural Processing Laboratory and Agricultural Product Analysis Laboratory of Faculty of Agriculture, Riau University of Pekanbaru from June to August 2017. From several parameters used, it was found that fruit maturity and extraction method had significant effect on free fatty acid content, iodine number, saponification number, peroxide number, and yield. However, the maturity and extraction methods have no significant effect on oil viscosity. High levels of fat and iodine number in bintaro seeds cause it potential to be developed into a source of vegetable oil.Finally, it is found that the best treatment for bintaro seed oil is by deriving it from 100% ripe fruit extracted using n-hexane solvent with yield of 52,93%, free fatty acid content 3,28%, iodine number  73.52 g I2 / 100 g, peroxide value 14.23 mg O2 / g, saponification value 203.67 mg KOH / g, and a viscosity value 63.28 cP.Keyword: Bintaro seeds, Soxhlet method, Free fatty acid, Saponification number, Viscosity.
