Rubber plantations play a vital role in the economy of Riau Province; however, rubber production is often influenced by various factors such as climate, government policies, and market conditions. This study aims to develop a rubber production prediction system for the regencies and cities in Riau Province using the Support Vector Regression (SVR) algorithm. The data used in this research is se…
Increasing yields without expanding planting areas is a challenge in oil palm plantations, which can be achieved through the development of superior varieties. One approach is to build a predictive model based on gene expression data, which reflects important genetic activities in regulating physiological processes, such as growth and fruit formation. Currently, there are 388 oil palm plants wh…
Small and Medium Enterprises (SMEs) play an important role in Indonesia's economy but still face various challenges in business development. To address these issues, the government, through the PLUT-KUMKM program, provides mentoring services for SME actors. This study aims to measure the success of PLUT-KUMKM partners using the Decision Tree J48 algorithm. The model was developed based on attri…
Employee Performance Assessment is one of the important aspects to manage Human Resources at PT. Baja Diva Manufaktur Pekanbaru in order to determine employee salary levels. So far, employee salary determination is still done manually so that the company still has difficulty in deciding the amount of salary that is appropriate for employees. The purpose of this research is to overcome this prob…
This final project discusses the development of mixtilinear incircle on angle trisectors in morley triangles. An angle trisector is defined as a line that divides an angle into three equal parts. If an angle is divided by two trisector lines, then each part of the resulting angle has the same size, which is one-third of the original angle. Mixtilinear incircle are internally tangent to the side…
This study discusses the implementation of block matrix inversion in input- output analysis of domestic transactions in Indonesia. A block matrix is a large matrix composed of smaller submatrices, used to simplify the inversion process in domestic transaction tables. The constructed block matrix is then analyzed using input-output analysis to measure the extent to which one sector influences an…
This final project discusses the modification of the Simpson’s 1/3 rule for approximating the Riemann-Stieltjes integral. The modification involves de- termining the coefficients of a monomial function of a certain degree, resulting in a second-order accuracy. The error is derived from the difference between the exact solution and the approximate solution. Numerical tests on several nonlinear…
This final project discusses the recovery of energy recurrence in a heterogeneo- us FPUT-β system with parameter variability. The tolerance values considered include 5%, 10%, 50%, and 95%. Moreover, several tolerance distributions su- ch as random, ascending, and centrosymmetric are introduced as approaches to restore energy recurrence in the FPUT-β system. The FPUT-β system is solved numeri…
This final project discusses three forms of iteration methods developed using the homotopy perturbation technique to solve nonlinear equations. The derivation of this method utilizes the Newton method approach, which is then improved by the homotopy perturbation technique so that a power series solution is obta- ined which forms three new iteration methods. Convergence analysis based on Taylor …
This final project discusses the Hamiltonian cycle on a new graph, namely the wijaya kusuma flower graph which is constructed by representing the original wijaya kusuma flower structure into a graph form. The vertex set V represents the flower structure such as the pistil, stamen, petals, and sepals, while the edge set E represents the relationship among these components. A Hamiltonian cycle is…
Adenovirus is a DNA virus that causes infections in the upper or lower respira- tory tract, pharynx, gastrointestinal tract, and conjunctiva.
