This final project discusses a new eight-order iterative method for finding a multiple roots of nonlinear equations. Analytically it is showed using Taylor expansion, geometric series and binomial series that the iterative method has eight order of convergence. The discussion is also focused on two specific forms of the discussed method. Some numerical examples are used to see the performa…

The study was conducted in December 2018- April 2019 at the rubber plantation in Kampar Regency and the Soil Science Laboratory, Faculty of Agriculture, Riau University, Pekanbaru. This r…
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…
