CNC machines are machine tools that can be operated automatically. Usually CNC machines can only do one machining process only, so it is considered less effective. Based on this, researchers did some research on tool machines that are able to perform two machining processes at once (CNC Hybrid). In the manufacture of CNC Hybrid, the one that should be considered is a machine control system that…

Jigs and fixture is a tool used to mass produce a component with the same shape and size, so that it becomes the desired production item. Jigs and fixture is a production workpiece holder that is used in order to accurately reproduce components. This construction is to connect the two devices, jig and fixture needed as a link between the top and bottom positions of the press and to grip the wor…
The biomass developed from the results of these oil palm trunks is wood pellet (wood biomass energy). Densification of biomass (forestry, agriculture and plantation waste) into biopelet is one method of developing the function of a resource that is increasing the energy content of each unit of volume, reducing the amount of ash in combustion and increasing heat capacity. The purpose of this…
This research aims to explain the general conditions of Indonesian defense equipment until 2014, to find out the reasons Indonesia chose Russia in purchase cooperation for fighter flight in 2015, and systematically analyze Indonesia and Russia in purchase cooperation of Su-35 fighter flight in 2015-2018. The research using Neorealism perspective, which nation-state as the level of analysis. T…
Studies on the combination of organic mulch and earthworms density on the properties of Dystrudepts and oil palm production are scarce. This study aims to determine the effect of organic mulch, earthworm density and it’s interactions and determine the combination of organic mulch and earthworm density which results in improved Dystrudepts properties and the best oil palm production. This rese…
The availability of goods is one thing that is important in the course of business. The way the store owner in meeting market demand is very influential with the profits obtained, one of them by providing inventory. The owner requires to determine how many goods used as inventory to meet consumer demand. This study aims to create a system of forecasting drug sales at the Dean Tigano Pharmacy, u…
This research was conducted to determine the adaptation of several soybean genotypes planted in two shade conditions according to the age of the oil palm plantations. This study was conducted by using a split plot design with 3 replications. Three levels of shading including shading caused by 3 years old oil palm tree, 5 years old oil palm tree and control were assigned as the main plots. Eight…
Potassium losses through leaching on peat soils are very high. Research on the effect of lime and NPK slow release on potassium loss is still limited. This study aimed to determine the effect of dolomite, a type of NPK slow release and the interaction between the dolomite with NPK slow release of the rate of loss of nutrients in the peat soil and to find the dose that can reduce the rate of lea…
Sales transaction data is often only considered as an archive without any attempt to dig into the data. Extracting the data is done by using data mining to obtain the information contained in the data. The purpose of this study is to analyze the purchasing patterns of baby gear products using the FP-Growth algorithm. Research conducted on 937 of transaction data in January 2019 until June 2019 …
The Pekanbaru-Dumai toll road project is one of the toll roads that has been commissioned by the government. This toll road is located in Riau Province, precisely in the City of Pekanbaru, Siak Sri Indrapura Regency, Bengkalis Regency, Kampar Regency, and Dumai Regency. The Pekanbaru-Dumai Toll Road will connect the economic corridors in Riau Province including Pekanbaru - Minas - Kandis - Duri…
Delima Elektronik is a shop engaged in the sale of electronic goods. Inventory uncertainty is one of the problems for shop owners to determine the supply of electronic goods within a certain time. To assist shop owners in determing the amount of inventory, forecasting can be done by using the double exponential method and its level of accuracy with MAD and MSE errors. The date used in this stud…
The Sumatra 500 kV Transmission Project is the main project supporting the transmission line below and first on the island of Sumatra. The Project Performance of Sumatera 500 kV Transmission is located Riau with a path length of ±160 kms and a total of 379 tower foundation points but in its implementation the project experienced a time delay. The absence of similar research especially in the d…
Rice (Oryza Sativa L) is one of the most important cultivation plants for human survival. Rice plant diseases often result in the growth of rice plants to be disrupted and can even make rice production fail. Lack of knowledge of information about the causes of rice disease and how to prevent this disease, a system is needed to classify types of rice disease based on their symptom characteristic…
Scheduling is arranged so that the time division of the activity plan goes according to plan. There are several components that affect the scheduling such as lecturers, students, the amount of space and time available to make the scheduling process requires very high accuracy and relatively little time estimation. To simplify the process of making course schedules, several algorithms appear to …
Mango must ripe to be more tasty. This is because ripe mango more sweeter than unripe mango. Sometimes, farmer checks for ripeness so that it can be enjoyed by mangoes lovers. This checking process called classification. This research purpose to do ripe and unripe mango identification and formed CNN classification model that was used for new mango image data. This research started from taking i…
Based on the data of Undergraduate Program (S1) students in the Mathematics Study Program of FMIPA, Riau University, many students take more than 8 semesters. This shows that there are still many undergraduate students in mathematics taking more than the scheduled time of 8 semesters. This certainly affects the quality of Riau University as a tertiary institution. The number of students who gra…
This final project discusses the application of the Chebyshev’s method to solve a nonlinear second order differential equation with boundary conditions. The Differential equations are discretized by finite difference methods to produce a nonlinear system. Furthermore, the nonlinear system is solved by the Chebyshev’s method. Computational tests are performed to see the convergence rate…
The final project discusses the least cost approach method based on the weighted opportunity cost to solve transportation problems. Weighted opportunity cost are formulated by considering supply and demand entries as weighted factors. Then by incorporating weighted opportunity cost table in the least cost method an algorithm is obtained to determine a better initial basic feasible solution.…
This final project discusses solving the traveling salesman problem in the form of an octagonal fuzzy number. The process is started by converting the octagonal fuzzy number into crisp numbers using the Robust’s ranking method , then to get the optimal solution the Hungarian method is used.
