Development of interval numbers have shown various beliefs regarding the arith- metic and the formulas. There are several multiplication and division operations that apply to interval numbers, but those operations have the same problems such as the result of multiplying an interval number and its inverse does not produce an identity and division is undefined if several conditions are not met. …
One of the problems in the field of optimization is the determination of vehicle routes. Determining the shortest route is very important because waste pickup must be done in a short and timely manner by maximizing the use of trans- portation equipment to reduce transportation costs. Therefore, it is important to design the route and pickup of waste. This research focuses on the design of the V…
This final project discusses the entry age normal and projected unit credit methods with Pareto distribution to determine normal pension contributions. The entry age normal method is a method that assumes that every employee is already a participant in the pension program when first hired or after meeting the requirements and the projected unit credit method is a method that divides the total p…
This final project discusses the alternative diagonalization process on the tri- angular fuzzy number matrix of size n n in parametric form. Many forms of arithmetic operations have been given by the author, especially triangular fuzzy numbers. For addition, subtraction and scalar multiplication operations there is not much difference while for multiplication, division and inverse there are m…
This final project discusses the pattern generation method to solve the cut- ting stock problem with a 2-dimensional size. The pattern generation method produces a feasible cutting pattern which is then converted to a linear program- ming model with an objective function to minimum the use of stock materials. The research was conducted at Handal Karya Buana company which is a glass cutting comp…
This final project presents fractional derivatives for composition of trigonome- tric functions using the Caputo concept and the limit concept. The fractional derivative order is 0 < α 1, α is a fractional number. This final project re- sulting a present comparison of the performance of the Caputo concept and the limit concept in handling composition of trigonometric functions. Fractional …
A worker is eager for a guaranteed life in old age. A worker is not always in maximum condition, so a worker must have a plan from the beginning so that they can guarantee their old age. worker must have a plan from the start in order to guarantee welfare in the future when entering retirement age, among other solutions is by participating in a pension fund insurance program. This thesis discus…
Each insurance participant pays a premium to the insurance company during the coverage period. In paying the sum insured to insurance participants, insurance companies need to prepare reserve costs. This reserve fee is used to pay for the needs of insurance companies and insurance participants. The purpose of this research is to determine the full preliminary term reserve of last survivor endow…
This final of project discusses the solution of sensitivity analysis of grey linear programming using simplex method. Sensitivity analysis is used to determine the limits of grey number changes in the objective function coefficients, changes in the value of the right-hand side of the constraint function, and changes in the nonbasic column coefficients of the constraint function so that the opti…
This final project discusses the interaction of two populations consisting of predator population and prey population in an ecosystem. The predator-prey model used is the Lotka-Volterra model with nonlinear prey harvesting and square root functional response. The nonlinear prey harvesting considers pre- dator harvesting rates that are not proportional to prey population size. The predator-prey …
In general, the stock cutting problem is a problem of standard cutting of a ma terial into pieces of a predetermined size according to the amount of demand and optimizing a certain objective function. This research develops a standa rd stock cutting rule at the wooden pallet company CV. Triyunda Jaya with multiple stock length size so it can generate the best cutting pattern with mi nimum…
This final project discusses the dynamic behavior of the Leslie-Gower predator- prey model which involves the interaction of the predator and prey populations with the growth rate of the predator population being proportional to the num- ber of prey which are available. The model described involves a type-I Holling functional response and a prey population influenced by Allee, where the type- I…
This research aims to produce an educational game as learning media based on Adobe Flash Professional CS6 equations and inequalities for linear absolute values of one variable to overcome learning burnout. The development model is 4D (define, design, develop, and disseminate). One-to-one trial subject test in this research is three 8th grade students of SMP/MTs, a practical test subject for a s…
This research aims to improve the learning process so that it can improve students' mathematics learning outcomes by applying the Problem Based Learning (PBL) learning model. This type of research is a classroom action research with the research subject of grade X-1 students of SMA N 1 Gunung Toar for the 2023/2024 academic year consisting of 33 students. The data collection instruments used in…
This research aims to improve the learning process and increase the mathematics learning outcomes of class VII students at SMPN 3 Sabak Auh in the material on whole number and fraction operations. The form of this research is Classroom Action Research which consists of planning stages, implementing actions, observing and reflecting. The research subjects were class VII students at SMPN 3 Sabak …
The research was based on low mathematical problem solving abilities of students in class VIIIB SMP IT Al Fityah Pekanbaru. The number of students who achieved the maximum score before action in the indicator of understanding the problem was 56% - 60%, planning the problem 0%, implementing problem solving plan was’nt obtained because students only carried out calculations and filled answers a…
This research aims to improve the mathematical problem solving abilities (KPMM) of class VIII.1 students at Babussalam Middle School Pekanbaru odd semester of the 2023/2024 academic year by applying the problem based learning (PBL) model to straight line equation material. This research is Classroom Action Research (PTK) which will be carried out in two cycles with the stages in each cycle cons…
This development research aims to produce learning tools in the form of Syllabus, Learning Implementation Plan (RPP) and Student Activity Sheet (LAS) based on Problem Based Learning to facilitate mathematical problem solving skills that meet the valid and practical requirements. This development research uses the 4-D model (Define, Design, Develop, and Disseminate). At the define stage, student…
The purpose of this research is to produce learning media that can facilitate students' mathematical understanding abilities on circle material assisted by iSpring Suite 10 software with a Discovery Learning model that can be accessed on Android smartphones and laptops and has met the valid and practical requirements. The development model used is the 4D model, with the stages of define, design…
This thesis discusses the inverse and general inverse of a trapezoidal fuzzy number matrix. Suppose u = (a, b, α, β) an arbitrary trapezoidal fuzzy number which is converted into fuzzy intervals to determine the mean or m(u) of the fuzzy number. The middle value is used to construct the arithmetic of multipli- Furthermore, the constructed arithmetic is used to determine the inverse of the …
