Abstract

This research aims to form a mathematical model in the problem of optimizing the average yield of cassava and soybean yields in West Pasaman Regency based on data from the West Pasaman Statistics Agency from 2007 to 2017 regarding the harvest area and average production of cassava and soybeans. The solution to the average production optimization problem uses the Wolfe's Method of Quadratic Programming. Wolfe method is used using a two-stage simplex iteration. The mathematical model formed is a non-linear equation. The estimation of parameters in the mathematical model uses the least squares method, which is calculated using the Matlab software. Optimization results using the Wolfe Method Quadratic Programming obtained an average of 340.95 kw / ha of cassava and soybeans, with an optimal harvest area of 255.38 ha of cassava and 469.5 ha of soybean harvest area.

Abstract

The purpose of this study is to examine how individual competence and internship satisfaction affect trainees' career motivation at Harris Resort Barelang Batam. This study employed a quantitative approach with a causal-associative research design. Purposive sampling was used to select 80 respondents from the study population, consisting of trainees from Batches 14 and 15 at Harris Resort Barelang Batam. Data were collected using a five-point Likert scale questionnaire. The data were analyzed using multiple linear regression with SPSS version 27, supported by validity, reliability, classical assumption, t-test, and F-test analyses. The findings indicate that internship satisfaction has a positive and significant effect on career motivation (β = 0.161; p = 0.025). In addition, individual competence has a positive and significant effect on career motivation (β = 0.764; p < 0.001). Simultaneously, internship satisfaction and individual competence have a significant effect on career motivation (F = 19.164; p < 0.001). These findings suggest that trainees' motivation to pursue a career in the hospitality industry can be enhanced through satisfying internship experiences and strong individual competence. Therefore, higher education institutions and industry partners should improve the quality of internship programs while supporting the development of trainees' competencies to strengthen work readiness and career motivation in the hospitality industry.
