ABSTRACT Fusarium wilt disease caused by Fusarium oxysporum is one of the diseases can decrease yield of shallot plants. Control methodes that is more environmentally beneficial is using biological agents namely endophytic Trichoderma spp.. The research aims to determine the compatibility of three isolates endophytic Trichoderma spp. and obtain the best consortium in inhibiting F. oxysporum …
This nal project studies the transformation of multi-choice linear programming (MCLP) problem to a standard linear programming problem (LP). The transformation involves linear combination of binary variables and then solve them by using standard linear proramming software (Matlab). The result of this discussion is that the optimal solution of the MCLP problem and for each the right hand s…
ABSTRACT The contents of the rumen of cattle are ruminant animal slaughter waste in the form of a collection of feed material that has not been fully fermented and which has not been fully digested by slaughtered cattle. NPK fertilizer is compound fertilizer that has been formulated in such a way by the factory, so that it can be used immediately. The research aim to examine the effect of inte…
ABSTRACT The aim of this research was to find out the influence of phosphate solubilizing bacteria (PSB) and to obtain optimum dose for rice growth and production (Oryza sativa L.) through SRI modification. The experiment was conducted in an experimental field of Faculty of Agriculture, Riau University, in February until May 2019. The experiment was conducted using completely randomized desi…
ABSTRACT This research aims to suppress the pathogenic attack of Phytophthora palmivora Butler fungi on cocoa seedlings by using dilution levels of B. subtilis F. Cohn so that cocoa seedling growth become better. The research carried out in the Plant Disease laboratory and experimental gardens Faculty of Agriculture, University of Riau.

This final project discusses some proofs of Fibonacci-type Pythagorean triangle in determining a sequence {△F,n : n > 0} with △F,n is Fibonacci Pythagorean triangles constructed by Fibonacci numbers Fn, investigates interrelationships of △F,n and △F,n+1, then considers inradius of Fibonacci Phytagorean triangles. Fibonacci type Pythagorean triangle is proved by using direct method a…
ABSTRACT This study aims to determine the effect of planting media and immersion duration with natural onion PGR and obtain planting media and immersion duration with onion natural PGR for the best growth of rose cuttings. The study was conducted in the Experimental Station of the Faculty of Agriculture, University of Riau, from March to May 2019. The study used a factorial Completely Ran…
This final project discusses the linear multistep method for finding a root of nonlinear equations. This method is obtained by applying an inverse rule to the explicit multistep method for obtaining the solution of ordinary differential equations (ODE solver). Theoretical studies using the properties of the monotonous sequences indicate that proposed method is convergent. Furthermore from …
