Abstract

This study aims to determine the antimicrobial activity of lactic acid bacteria isolate from soybean epiderm against pathogens Escherichia coli 0157 and Staphylococcus aureus ATCC-25329. The experiment was conducted experimentally using Randomized Complete Design (RAL) with three treatments and five replications to obtain 15 experimental units. The treatment used lactic acid bacteria isolates from soybean epiderm namely K.12.3, K.13.1 and K.22.1 tested in petri dish that already contained pathogenic bacteria Staphylococcus aureus ATCC-25923 and Escherichia coli 0157. Antimicrobial activity was tested using well agar diffusion method and the data obtained were analyzed using ANOVA and continued with DNMRT advanced test at 5% level. The results showed that the lactic acid bacteria of the soybean epiderm had a greater inhibition against Escherichia coli 0157 compared with Staphylococcus aureus ATCC-25923. Isolate K.13.1 was not significantly different in inhibiting Escherichia coli 0157 which resulted in inhibition zone of 8.313 mm and Staphylococcus aureus ATCC-25923 with inhibition zone of 6.960 mm. Mean while, the cell-free supernatant K.22.1 isolate significantly different in inhibiting Escherichia coli 0157 with inhibition zone of 6.860 mm and Staphylococcus aureus ATCC-25923 resulted in inhibition zone of 5.760 mm.

Abstract

The rubber shell contain beneficial compounds lignin and cellulose which is quite high and has not been utilized optimally. Therefore, this study aims to take advantage of rubber shell as the main material for the manufacturing of charcoal briquettes and charcoal briquettes obtain formulations are of good quality. This study was conducted experimentally using Complete Random Design (CRD) with 4 treatments and 4 replications and continued with Duncan’s New Multiple Range Test (DNMRT) at 5% level. Treatments at this research were P1 (adhesive 3%), P2 (adhesive 5%), P3 (adhesive 7%), P4 (adhesive  9%). Results of the analysis of variance indicate that the ratio of adhesive has a significant effect on water content, ash content, density, volatile content, carbon content, and calorific value. The best formulation was obtained from 5% adhesive that had 5.52% water content, ash content 15.47%, 0.46 g/cm3 density, 13.47 vapour content, 65.52 tied carbon, and heating value 5.153.03 cal/g. Keywords : charcoal, rubber shell, charcoal briquttes

Abstract

This subject proposes to find out the result of oil palm seed immersion in various concentrations of KNO3 and to get the best KNO3 concentration on germination and outgrowth. This research has been conducted at Plant Breeding and Experimental Plantation Laboratory, Faculty of Agriculture, University of Riau. The study was conducted for 4 months from Agust to December 2016. The experiment was conducted experimentally using Completely Randomized Design (CRD) consisting of 4 treatments and 5 replications. The treatment of soaking of scarificated oil palm seed in KNO3 (K) concentration for 20 hours consisted of K0 (soaking without KNO3), K1 (0.2%), K2 (0.4%), K3 (0.6%). Parameters observed were ; germination time, index value test, percentage of sprouts, radicle length, plumule length, seed height, and seedling dry weight. The data obtained were analyzed statistically by using analysis of variance and means separation with Duncan Multiple Range Test at 5%. The result showed that soaking of oil palm seed in KNO3 solution had a significant effect on sprouts, germination percentage, radicle length, plumule length and dry weight of seedlings. Soaking of oil palm seed in a KNO3 solution with a concentration of 0.4% for 20 hours can accelerate when sprouts appearing from 22.4 days to 6.8 days, and increase germination rates from 34.4% to 53.6%. Key Words : Oil palm seed, dormancy, KNO3 and germination

Abstract

Agroforestry is one of the land management systems that can be offered to overcome the problem of forest land convertion. The success of agroforestry  plant growth is influenced by aspects of which are protection from pests. Pest attacks can decrease the potential of standing, both quality and quantity. This study aims to determine the intensity of pest attacks on agroforestry of teak stand (Tectona grandis). Research activities carried out on the Rajawali Sakti street Simpang Baru village Tampan districts. The method used in this research is random sampling. The area covered is 3 Ha with sample intensity of 10% that is 0,3 Ha. An observation plot was made of 10 m x 10 m of 30 plots. The research indicate that the intensity of pest attack on stand of teak is amount to 22,13% which is included in the category of minor damage. Pests that attack teak plants such as caterpillar teak (Hibea puera), white lice (Paracoccus marginatus), white butterfly (Bemisia tabaci), termites (Neotermes tectonae) dan black ants (Polyrhachis Spp). Keywords : Agroforestry, Teak stands (Tectona grandis), Pest, Intensity of attack (IS).

Abstract

Soybean (Glycine max (L). Merril) is one of grain-producing crops which has high value of nutrition and has been cultivated in Indonesia since the 16th century. Soybean plays an  important role in human diet as alternative source of protein and oil. The aim of this research is to determine the response of soybean varieties on planting density and to determine the suitable planting space for specific varieties to be used in cultivating soybean. A field experiment was conducted using a randomized block design with 3 replications. The six varieties, ie; Argomulyo, Anjasmoro, Kaba, Burangrang, Gema, and Grobogan, were planted in a plot of 3 m long and 2 m wide  3 m with plant spacing of 40 cm x 20 cm, 40 cm x 15 cm, and 40 cm x 10 cm. The traits observed were plant height, leaf area, leaf area index, flowering date, harvest date, number of seeds per plant, seed weight per plant, seed yield per m2, and 100 seed weight. The results showed that except for leaf area and grain number per plant, most parameters observed varied among varieties. Soybean varieties grown with less  density had taller stem, smaller value of leaf area index and smaller seed size. The  magnitude values of most parameters were almost similar among planting densities indicating that planting density did not affect those characters. Keywords: Soybeans, Varieties, Plating space

Abstract

This study aims to determine the response of water spinach to rice straw and NPK compost, and looking for a best combination of rice straw and NPK compost that provides the best growth and production of water spinach. This research carried out in the Faculty of Agriculture Experimental Station, Riau University, starting from February 2018 until May 2018. This study used a Randomized Block Design with 2 factors and 3 replications. The first factor was rice straw compost (0, 7 and 14 ton.ha-1) and second factorI namely NPK fertilizer (0, 100 and 200 kg.ha-1). The parameters observed were plant height, leaf number, leaf area, fresh weight, root shot ratio and plant dry weight. Data were analyzed using anova and with HSD 5%. Increasing the dosage of rice straw compost significantly increased plant height, leaf number, leaf area, fresh weight, root to shoot ratio and dry weight of land water spinach. The interaction of giving rice straw compost and NPK fertilizer significantly increased plant height, leaf number, leaf area, fresh weight, and dry weight except the root canopy ratio of land water spinach. The interaction of rice straw compost 14 ton. ha-1 in NPK 200 kg. ha-1 was the best dose to increase plant height, leaf number, leaf area, fresh weight, root canopy ratio and dry weight of land water spinach. Keywords: Ipomoea reptans Poir, rice straw compost and NPK fertilizer
