Abstract

This study analyzes investment strategies based on Modern Portfolio Theory (MPT) using a case study of two Malaysian construction companies, Bina Puri Holdings Bhd and Ahmad Zaki Resources Berhad (AZRB). The study evaluates the risk and return of both companies' stocks using variables such as average closing price, average return rate, variance, and standard deviation. The results show that Bina Puri Berhad has a higher average return (36.43%) compared to AZRB (11.23%), but it also comes with higher risk. The correlation between the two stocks was found to be weakly positive (0.1759), indicating potential diversification benefits within a portfolio. By applying MPT principles, the study identifies the optimal portfolio combination that minimizes risk while maximizing returns. The findings highlight the importance of diversification in portfolio management and the relevance of MPT in strategic investment decision-making.

Abstract

Bullying remains a pervasive concern in Indonesian elementary schools, with approximately 30% of reported cases occurring at the primary education level. This community service study examines the implementation and effectiveness of an anti-bullying seminar conducted by university students from Universitas Darunnajah for elementary school children in Cidokom Village, Bogor Regency. The program employed a participatory action approach that integrated interactive seminars, role-playing activities, and psychoeducational workshops, targeting 85 students in grades 4 through 6. Pre-test and post-test assessments were administered to measure changes in students’ knowledge of how to identify bullying, empathy levels, and intentions to intervene as bystanders. Descriptive statistical analysis, supplemented by qualitative observational data, revealed significant improvements across all measured indicators. Students’ knowledge of bullying types and recognition increased from a mean score of 52.4 to 78.6, while empathy scores improved from 48.7 to 74.2. Bystander intervention intentions rose from 45.3 to 76.8. Qualitative findings indicated heightened student engagement and increased willingness to report bullying incidents. This study contributes to the growing body of literature on university-community partnerships in bullying prevention. It demonstrates the viability of student-led community service programs as vehicles for promoting safe school environments in rural Indonesian communities.
