Abstract

This study aims to determine the optimal portfolio formation using the single index model method on LQ 45 Index stocks for the period from March 2020 to December 2021. The population in this study consists of all company shares included in the LQ 45 Index during the specified period, totaling 45 stocks. A sample of 36 companies was selected using a nonprobability sampling technique with a purposive sampling method. Data collection was carried out using documentation techniques, primarily focusing on collecting closing stock price data. The data analysis process involved collecting the closing stock price data and utilizing the single index model method to identify an optimal portfolio. The results of this study indicate that 18 company shares were included in the optimal portfolio. These companies are ADRO (7.46%), AKRA (14.51%), ANTM (7.97%), ASII (4.42%), BBNI (3.3%), BBTN (1.8%), BMRI (4.55%), CPIN (1.45%), ERAA (11.14%), EXCL (3.19%), INCO (8.55%), INKP (3.98%), ITMG (5.08%), JPFA (4.86%), JSMR (3.37%), KLBF (8.3%), TKIM (1.85%), and TOWR (4.23%). The expected return for the portfolio is 4.38% per month, with a portfolio risk borne by investors of 0.29% per month. The study suggests that constructing a portfolio with the identified stocks can yield favorable returns. However, it is crucial to regularly reassess and adjust portfolios due to changing market conditions and individual risk preferences. The implications highlight the benefits of using the single index model for portfolio formation. By considering the relationship between individual stocks and the LQ 45 Index, investors can make informed decisions to maximize returns while managing risk. These specific stocks can serve as a starting point for further research in portfolio management.

Abstract

Workload refers to the volume and intensity of tasks and responsibilities assigned to interns during their internship period. It encompasses the amount of work, deadlines, complexity, and the level of autonomy given to students. Compensation, on the other hand, refers to the monetary or non-monetary benefits provided to interns for their work. This study aims to determine the effect of workload on job satisfaction, the effect of compensation on job satisfaction, and the effect of workload and compensation on student job satisfaction in the Certified Independent Study & Internship Program (MSIB) Batch 3 PT. INKA Multi Solusi Service in Madiun City. The study utilizes quantitative data obtained from questionnaires distributed to 35 participants. The data were analyzed using the simple linear regression analysis method with the help of SPSS for data processing to prove the hypothesis. The results indicate that the workload variable has a significant negative effect on job satisfaction, meaning that higher workloads are associated with lower job satisfaction. Conversely, the compensation variable has a significant positive effect on job satisfaction, meaning that higher compensation leads to higher levels of job satisfaction. Simultaneously, the variables of workload and compensation show a significant combined effect, suggesting that lower workloads and higher compensation result in higher job satisfaction among students in the 3rd batch of the Certified Independent Study & Internship Program PT. INKA Multi Solusi Service in Madiun City.
