This paper discusses an inventory model with deficiencies in triangular fuzzy numbers.
The inventory model used is an EOQ model. The optimal solution of the
model is achieved using the Kuhn-Tucker conditions. Then, ...
This article discusses a two-step iteration method without memory for solving ab-
solute equations. The convergence analysis performed shows that the two-step iter-
ation method without memory has a linear convergence ...
Peatlands are the result of the decomposition of organic matter under anaerobic
conditions that naturally accumulated over hundreds of years. A massive
conversion of land function can lead to peatland degradation which ...
This paper discusses the solution of assignment problems in the form of mixed
objective assignment costs. The assignment costs used are triangular fuzzy numbers
and crisp numbers. Triangular fuzzy numbers are converted ...
Rubber seed shells have chemical composition of cellulose, lignin, and pentosan as a
carbon source, which potentially to be used as charcoal which functions as an adsorbent.
This research aims to convert rubber seed ...
Giam Siak Kecil-Bukit Batu (GSK-BB) Biosphere Reserve is one of the areas in
Riau Province which has the largest area of peatland. Most of the peatlands in
Riau have been converted into plantations and industrial plantations ...
This article discusses the properties of BM-algebra and the relationship of BM-
algebra with BCI -algebra, BF-algebra and Coxeter algebra. Their relationship
through the properties of BM-a
Rubber seed shells (Hevea brasiliensis) contain fiber and various carbon compounds
such a selulose, hemicellulose and lignin which are potentially used as adsorbents. In
this study, rubber seed shells was carbonized at ...
Biosphere Reserve GSK-BB is an area of peat ecosystem that has been largely
converted, causing a decrease in the quality of the peat. Generally, the parameters
of peat quality use biological, physical and chemical factors. ...
Peatlands in the Biosphere Reserve Giam Siak Kecil- Bukit Batu (GSK-BB), Riau are
mostly converted into Timber Plantation (TP) Acacia sp., oil palm plantation, rubber
plantation and settlements. Peatland conversion will ...
This paper discusses the trapezoidal fuzzy numbers transportation problem with one
point approach to optimize. The coefficents of cost, supply and demand are a fuzzy
number that appears because there are uncertainty that ...
This final project discusses the solution of assignment problems in the form equally
spread symmetric fuzzy numbers for minimization balanced case. The fuzzy numbers
does not need to be converted into crisp numbers and ...
Bambusa is the fourth most common type of bamboo in Indonesia. It has been reported
that the number of types of bamboo in Indonesia was 161 types or around 11.5% of the total
types of bamboo in the world. Kampar Regency ...
Composite is a material composed of two or more materials with different phases, namely a
matrix and filler. The composite used in this research of natural rubber latex as a matrix,
activated charcoal from mahoganiy fruit ...
Bangko Sub-district is one of sub-districts in Rokan Hilir Regency that has distributed
assistance of Keluarga Harapan (Family Hope) Program since 2007. The program is a
conditional social protection program from the ...
This paper discusses the solution of the travelling salesman problem. This problem is
solved using the genetic algorithm method with MATLAB software. This discussion
aims to nd the best solution of a route by a salesman. ...
This article discusses the new Newton iterative method based on nonstandard difference
for solving nonlinear equations. The proposed method is proven analytically to
have the order of cubic convergence. The computational ...
This article proposes a new single step iterative method for solving nonlinear equa-
tions. This iterative method is derived using the approximation formula of truncated
Thiele's continued fraction. Analysis of convergence ...
This article discusses travel planning around the mainland of riau province using
ant colony algorithm, utilizing the heuristic method, with Matlab software to a
variative solution. This discussion aims to find the ...
Combination of magnetic nanoparticles such as hematite (α-Fe2O3) and magnetite
(Fe3O4) was used as catalysts to degradate methylene blue in aqueous solution.
Magnetic nanoparticles were obtained from the natural sands ...
