Endophytic bacteria are bacteria living in plant tissues and symbiotic mutualism with their host. The excess production of bioactive substances from endophytic microorganisms among others, microorganisms are easy to grow, have shorter life cycles than plants and can produce large amounts of bioactive compounds. Endophytic bacteria found in plants generally originate from the roots and then spread through xylem tissue. Endophytic bacteria that live within the plant tissue for a certain period and are able to live by forming colonies in plant tissue without harming the host. Endophytic bacteria can be isolated from sterile plant tissue surfaces or extracted from inner plant tissue. The purpose of this study was to determine the type of bacterial isolate of edofit found in the root of Andaleh plant. The method used to isolate endophytic bacteria from the root plant Andaleh is streak plate method. Identification of bacteria macroscopically and microscopically. The results obtained were 16 isolates of endophytic bacteria from the roots of Andaleh plant seen from different colony forms. Identify microscopically with Gram staining

Studies have been conducted on cytotoxicity of sirsak (Annona muricata) against T47D cell line. However, the selectivity of Annona muricata leaf extract against MCF-7 breast cancer has not established. This study aimed to determine the index selectivity of Annona muricata leaf extract against MCF-7 breast cancer cell line. In this quasy experimental study using 2 kind of cell line, The MCF-7 breast cancer cell line and Vero cell line as normal cell were treated with Annona muricata leaf extract at dose 1000, 500, 250, 125, 62.5, 31.5 µg/mL respectively. The MTT assay were used to evaluate the viability of both cell line after treatment with Annona muricata leaf extract. The data of viability cells were analyzed with Probit regression to determine the IC50 value of Annona muricata leaf extract in both cell lines. The selectivity of two treatment was determine based on the selectivity index (SI) that represents the ratio of IC50 value of Annona muricata leaf extract. The IC50 value of MCF-7 and normal cell were 44.94 and 184.04 respectively with selectivity index 4. This result suggested that Annona muricata had cytotoxic effect in MCF-7 breast cancer cell line but not in normal cells. In conclusion Annona muricata leaf extract has cytotoxic effect to MCF7 breast cancer cell selectively.

Total fish consumption during 2011-2015 showed an increase of 6.27%. The waste is estimated to be about 75% of the total weight of the fish. Thirty percent of the total 75% of fish processing waste is bone and skin. The collagen sources on the market is limited to cowhide and pig skin derived. Therefore, collagen from fish is expected to be an acceptable alternative source for all people because of its high availability and no risk of disease transmission. This study aimed to determine the difference of collagen content in manyung fish and snapper fish. Collagen extraction of manyung fish and snapper fish was done using alkaline and acidic solution. The soluble collagen concentration was measured by the standard Bradford solution using a UV-Vis spectrophotometer. The collagen concentration of manyung skin, snapper skin, manyung bone, snapper bone, and snapper scales obtained were 206.167; 202.833; 106.167; 77.833; and 24.50 ppm. The skin of manyung fish has the highest collagen content compared to other samples.

Pollution of crude oil on environmental can have an effect of nutrient uptake on plants and balance of ecosystems. Biodegradation. is one way to reduce petroleum pollution . The purpose of this research are determine the potential growth of actinomycetes local Riau (L11 and L121) in crude oil hydrocarbons at concentrations of 0%, 2%, 5% and to know their ability to degrade crude oil hydrocarbons at concentrations of 5%. This research observed the growth of each actinomycetes local Riau and the percentage of crude oil degradation by a single isolate and a consortium with gravimetric method. The results showed that the growth of L11 and L121 total population was not significantly different at addition crude oil of 2% and 5% but significantly different wth 0% (without crude oil). Test degradation of crude oil using single isolate gave significantly different results for the consortium isolates. Percentage of degradation crude oil by L11 was 23.5%, L121 was 19.2% and consortium isolate (L11 + L121) was 31.9% with an incubation time of 10 days in a minimum medium salts. This actinomycetes local Riau can be developed as biodegradation agents for crude oil on soil and water.

ABSTRACT Aquilaria malaccensis is one of the agarwood-producing plants that have high economic value and has been included as a type of Appendix II by CITES, where its consequences in the formal trade,agarwood have to produced from agricultural trees instead of trees that come from nature. A.malaccensis cultivation can be done with vegetative propagation one of them by cutting. In plant propagation with cuttings required additional nutrients and natural auxin, in order to encourage roots and accelerate plant growth. One of them is by utilizing cow waste water and processed into biourine.The aim of this research was to find out the growth of A. malaccensis cuttings along with giving the biourine of cow and also the most optimal biourine concentration. The study used a completely randomized design (CRD) with 5 exercises and 3 replications. The treatment consisted of: B0 = 0% concentration biourine (without giving biourine), B1 = Biourine with a concentration of 25%, B2 = 50% biourine concentration, B3 = Biourine with a concentration of 75%, and B4 = Biourine with a concentration of 100%. The results of the study showed that biourine beef growth on A.malaccensis cuttings was seen in the parameters of plant height, leaf length, leaf width, shoot length and root length. However, it was not adequate for the number of leaves and the number of shoots. The best result for growth of A.malaccensis cuttings at75% concentrations.Keyword: Aquilaria malaccensis, RAL, Biourine

This study aims to determine the types of weed vegetation in oil palm plantations (Elaeis guineensis Jacq) in Tebing Tinggi Okura, Rumbai Pesisir Sub-District, Riau. The research procedure starts from the field survey, the determination of the station is done by purposive random sampling method and is determined by three research stations namely Station I (3-5 years), Station II (5-7 years), Station III (> 7 years). Data is analyzed base on density, frequency, important value index, species diversity index (H '), dominance index, evenness index, uniformity index or similarity. The results were obtained nine types of weeds that are Asystasia gangetica weeds, Calopogonium mucunoides Desv., Davallia denticulata, Dianella ensifolia L., Elaphoglossum blumeanum, Eupatorium inulifolium Kunt, Imperata cylindrica Raeusch, Nephrolepis bisserata Schott., and Wrightia javanica.
