This nal project discusses a method for solving a quadratic fractional programming (QFP) problems. The method is called the decomposition method based on linear programming (LP) problem for nding an optimal solution to a quadratic fractional programming (QFP) problem, where both the numerator and the denominator of the objective function can be fatorized into two linear functions. The me…
This nal project discusses the solution of triangular fuzzy number linear programming. The method for solving triangular fuzzy number linear programming is called Mehar's method. Mehar's method is done by conversion the objective function and the fuzzy constraint functions based on the fuzzy linear programming problem to crips number based on operation of fuzzy number linear programming a…
To improve the performance of flying racing plane, in 2018 the team of Flying Robot Mechanical Engineering University of Riau again designed to build a second-generation racing plane-type rides named Serindit V-2. The construction process of Serindit V-2 has been completed in the design stage and the manufacture of fuselage mould. In this study, the stage was continued with the manufacture…
CNC machines are machines that can be operated automatically. Generally, CNC machines can work in one machining process such as milling, turning, drilling and others. Therefore, to increase the productivity of CNC machines, a CNC machine can be made to carry out several processing processes so that it becomes a CNC hybrid. To make a hybrid CNC required standard mechanical components, one o…
This final project discusses new estimators for population variance using two auxilary informations. This estimator ratio is completed by simple random sampling without replacement method. The result of this method is to get efficiency of estimators. Then to determine an efficient estimator is done by comparing the MSE (Mean Square Error) for estimator ˆ S2 rpG1 dan ˆ S2 rpG2 and varia…

Refined palm stem fiber can be used as a constituent of biopelet. Palm fiber fiber which is chopped on a commercial chopper still has problems in the blunt part of the blade and the results obtained have not been reached to the maximum. So that the design and manufacture of a palm oil chopper machine with a design capacity of 10 kg / hour is aimed at: (1) obtaining a design picture of a pa…

This nal project discusses how to solve the problem of traveling salesman in fuzzy triangles using dynamic programming. The process to obtain the solution begins by converting the fuzzy triangle numbers into crisp numbers using the Yager's ranking method and then the optimal solution is determined using dynamic programming. This nal project is a review of the article Mythili et al. [Inte…
This final project aims to make and assemble the Electrical System on T-Rex Car Tricycle. Body wiring is an installation from several sets of electrical systems from this vehicle. Some of these sets are the lighting systems which start from front lights system consisted of head light and city light, then the warning light system which consisted of brake light, turn signal light, indicators …
This final project discusses the stability between predator and prey in the modified Lotka-Volterra. This model uses a modified rational Lotka-Volterra model with one predator and one prey. In this model, there are two nonnegative equilibrium points and stability positive equilibrium in the parameters. Furtheremore, a simulation is given for each case that describes the behavior and stabil…
This study aims to obtain optimum liquid smoke from young coconut fiber with different destillation temperature treatments. This research was conducted using a Completely Randomized Design (CRD) consisting of 4 treatments and 4 replications to obtain 16 experimental units. The data obtained were statistically analyzed using ANOVA, if F is greater than or equal to F table, then continued with DN…
The aims of research was to determine the length of time in the air exposed phase and the immersed phase in the medium in order to obtain maximum becterial cellulose yields. The research was carried out experimentally using a Completely Randomized Design (CRD) with 5 treatments and 3 replications to obtain 15 experimental units. The treatment in the research were ratio between time of exposure …
The purpose of this research was to get selected treatment of microalgae Chlorella sp. as a reducing polutan of sago liquid waste with the concentration of Agrobost and utilize symbiotic technology between the two. This research used a complete randomized design (CRD) with 5 treatments and 3 replications. In this research was microalgae 800 ml/L (6,78 log Cfu/ml) of sago liquid waste with 5 tre…
The objective of this study was to obtain exact formulation of combination of yellow sweet potato puree and dry coconut dregs based on quality standards for making cookies. This study used a completely randomized design (RAL) with five treatments and three replications. The treatments of yellow sweet potato puree and dried coconut dregs on wheat flour consists of UK1 (70% yellow sweet potato pu…
Curcumin is a secondary metabolite that has diverse biological activities. However, curcumin has low bioavailability due to the presence of the β-diketone unit is easily hydrolyzed at physiological pH. Therefore the replacement of the unit with monoketone is expected to overcome this problem. We hereby report the synthesis of the piperidone derivative monoketone curcumin analogs. Synthesis was…
Jelutung (Dyera costulata) is a plant of the Apocynaceae family which is found in the Talang Mamak tribal, Kelayang District, Indragiri Hulu Regency, Riau Province. It is usually used by the Talang Mamak tribe as a medicinal plant to treat various diseases such as skin diseases, digestive infections, and throat infections (coughing). The plant contains secondary metabolites such as alkaloids, f…
