Abstract

Snakehead fish (Channa micropeltes Cuvier) is economical freshwater fish which are found in Kelubi Lake. Over time, Kelubi lake had changed by activity around the lake and impact on biota in it. The purpose of this research to gain information about aspects of snakehead fish reproduction in the Kelubi Lake which involve include density, sex ratio, level of gonad maturity, index of gonad maturity, fecundity, and egg diameter, along with aspects of marine environment Kelubi Lake. This research have been done at December, 2013 untill February, 2014. Sampling technique using Proportionate Cluster Random Sampling with fishnet stocking area 12,56 m2. Based on Catch per Unit Effort (CPUE) analyst is known snakehead fish density in Kelubi Lake is 439 fishes. Sex ratio between snakehead fish male and female is 2:1. Population is dominated by widhitebait with level of gonad maturity (TKG) I. Index of gonad maturity is about 0,03-0,94%,indicates that snakehead fish can spawn year-around. Snakehead fish fecundity as about 14.056 grains/fish and egg diameter range between 2,30-2,57 mm.

Abstract

Arbuscular vesicular mycorhizae (AVM) is a fungus that has mutualistic symbiosis with plant roots. Arbuscular vesicular mycorhizae (AVM) has ability to boost plant growth but information regarding this types of fungi at Mecca onion (Eleutherine americana) is still unknown. This study aims to determine the type of arbuscular vesicular mycorhizae (AVM) and level of infection at rooting of Mecca onion (E. americana). This research was conducted in Laboratory of Microbiology, Faculty of Mathematics and Natural Sciences, University of Tanjungpura from July 2014 to September 2014. The analysis of soil samplewas conducted at the Laboratory of Chemistry and Soil Fertility, Faculty of Agriculture, University of Tanjungpura. Isolation of soil samples employed two techniques, wet filter chamber and centrifugation. The study found that as many as 277 arbuscular vesicular mycorhizae (AVM) spores derived from genus Glomus(9 types), Acaulospora (3 types) and Paraglomus (1 type). The observation of root preparation indicated that structure of arbuscular vesicular mycorhizae (AVM) contained spores and hyphae with the percentage of root infection was 12,5%, and it is classified into low category.

Abstract

The low fertility and high soil acidity make the peat soils require processing before being used as a medium for plant growth. Peat soil improvement efforts need to be done on an ongoing basis. This study aims to determine the effect and the optimal dose on the using of bokashi straw and petrhikaphos fertilizer on the peanut plant growth (Arachis hypogaea). This study used Factorial Completely Randomized Design (FCRD) with 2 factors namely petrhikaphos fertilizer (A) and bokashi straw (B). Each factor consists of 4 levels, they are: control, 5g; 15g and 25g for petrhikaphos fertilizer and control, 18,75g; 37,5g and 56,25gfor bokashi straw fertilizer. The findings of the research showed that the using of bokashi fertilizer up to 56,25g dosage /plant has not been able to give a noticeable effect on the growth and yield of peanut crop production. Based on those four-dose  treatments which were given, the dose of 25g /kg of seed showed the best result for the parameter root dry weight, number of pods, seeds, seed weight, number of nodules and the total number of effective root nodules. There were no interactions between bokashi and petrhikaphos fertilizer on to all  observations A. hypogaea growth.

Abstract

Tofu is one of the most popular food in Indonesian society. Tofu has a relatively short period of storage ranging from 1-2 days to be consumed, so it takes process of preservation in order to extend its storage life. One of the natural materials that could potentially serve as a natural preservative is the Piper betle leafand the noni fruit (Morinda citrifolia). This research aims to determine the concentration of each effective extract, the total number of bacterial colony and the organoleptic test results. The research was conducted from May until September 2014. It was an experimental design using the Completely Randomized Design. The concentrations of the extract used were 0%, 3%, 6% and 9% for each extract of Piper betle leaf and noni fruit. The results showed that the effective treatments in slowing down the process of decay were the Piper betle leaf extract (9%) and noni fruit extract (3%) with an average Total Plate Count (TPC)8.23x1010CFU/g dan 6.7x1010 CFU/g. Both extracts were able to maintain the storage life of tofu in room temperature for 3 days. The Piper betle leaf extract (9%) and noni fruit extract (3%) had a high value in the organoleptic parameter (aroma, texture, color and taste).

Abstract

Stem canker caused by the Phytophthora sp. fungus is one of the diseases in langsat (Lansium domesticum).The disease can be controlled using biological agents in the form a rhizosphere fungus which is antagonistic against pathogenic fungi. This research aims to identify the types of fungi from the rhizosphere of langsat and determine the ability of these fungi in slowing down the growth of Phytophthora sp. The isolation of Phytophthora sp. fungus was done by the direct planting method, while the isolation of the rhizosphere fungi by the dilution method and the antagonistic test was performed with a paired method. The antagonistic fungi successfully isolated were Mucor sp.1 F1, Mucor sp.2 F2, Penicillium sp.1 F3, Penicillium sp.2 F4,Penicillium sp.3 F5, Penicillium sp.4 F6, Trichoderma harzianum F7 dan T. viride F8. Based on the research results, there of the growth of Phytophthora sp. was inhibited by the T. harzianum F7 with highest antagonistic percentage 68,93%.

Abstract

Bittervine (Mikania micrantha) is a kind of weed containing allelochemical compounds which can supressgrowth of plants nearby, so that Bittervine can potentially be used as bioherbicide. This research aims to testthe potentiality and effective concentration of M. micrantha leaves extract in inhibiting seeds germination and supressing growth of Blue tongue (Melastoma affine) weeds. This research was conducted at Biology Laboratory, Chemistry Laboratory and Green house facility of Math and Science Faculty of Tanjungpura University from May to September 2014. Completely Randomized Design was used in this research with extract concentration at 0 (g/ml), 0,17 (g/ml), 0,43 (g/ml), 0,82 (g/ml) and 1,5 (g/ml), each with three duplications. The result shows that the leaves extract of M. micrantha can inhibit seeds germination and supress the growth of M. affine weeds. The extract effective concentration that can lower the germinationpercentage and sprout length of M. affine was at 0,43 (g/ml). The extract effective concentration that can supress the growth of M.affine encompassing plant height, wet weight and dry weight was at 0,17 (g/ml).

Abstract

Bacterial phosphate solvent is bacteria that have role in enrichment of soil. Origin material and formation ofpeat soil have correlation with the maturity and the level of fertility of peat soil. The recent research aimed to find out genus and density of bacterial phosphate solvent at the level of maturity of different peat soil in protected forest areas of Ambawang Mountain in District of Teluk Pakedai, Kubu Raya Regency. The isolation of bacterial was conducted by using the media of pikovskaya and pour plate method, whereas bacterial density calculation was done by total plate count method. The research finding showed that there were five genera of bacterial phosphate solvent, namely; Acinetobacter, Chromobacterium, Flavobacterium, Micrococcus, and Stapylococcus. There was no different of the total density of bacterial colonies phosphatesolvent in fibric, hemic, and sapric.

Abstract

Nitrifying bacteria has an important role in oxidizing ammoniac to be nitrit which is required by plants. The purpose of this study is to investigate character and density of nitrifying bacteria at maturity level of peat soil. The sampel was taken at wildlife sanctuary of Ambawang mountain Kubu Raya district. The proses of isolation was conducted by pour plate method that applying spesific media of nitrification and total plate account was used to calculate the density of bacteria. Observation and identification was implemented macroscopically, microscopically and biochemically. The finding indicated that 5 genus of nitrifying bacteria had different level of maturity in peat soil. Nitrosomonas, Nitrobacter and Nitrosococcus were some types ofbacteria that were pound in fibrik meanwhile in hemik, Nitrobacter and Nitrosocystis were identified. In addition, in saprik, Nitrobacter, Nitrospina and Nitrosococcus were discovered. The total density of nitrifying bacteria colonies in maturity level of peat soil in fibrik, hemik and saprik was 160 x 105 CFU/g, 107,5 x 105 CFU/g, and 19 x 105 CFU/g.
