Abstract

This study aims to analyze the effect of financial ratios, specifically the Current Ratio (CR) and Return on Assets (ROA), on stock returns of food and beverage subsector companies listed on the Indonesia Stock Exchange (BEI) during the period 2022–2024. The approach used is quantitative with a descriptive method and multiple linear regression analysis, along with classical assumption tests to ensure data validity. The sample consists of 18 companies that meet the purposive sampling criteria based on the availability of complete financial statements, observation periods, and no losses. Data were obtained from annual financial reports available on the official BEI website and individual companies. The analysis results show that, simultaneously, both Current Ratio and Return on Assets have a positive and significant effect on stock returns, indicating that liquidity and profitability are important factors affecting investment returns in this sector. Partially, ROA has a significant positive effect on stock returns, while the effect of CR is positive but not significant. These findings provide strategic implications for companies in managing financial aspects and for investors in making investment decisions based on financial indicators. This study is expected to contribute to the development of knowledge in corporate finance.

Abstract

Two graphs are operated with various operations, one of which is Operation Corona. The graphs that are operated in this paper are circle graphs and star graphs. Both graphs are operated with Operation Corona. The graph resulting from the operation is then colored using the Greedy Algorithm. The Chromatic Number obtained from the results of the Corona Operation on a graph (Cn ⊙ Sm) is χC_n⊙S_m = 3 for every m,n ≥ 3, {m,n ∈ N}. Because the graph resulting from the corona operation is non-commutative, the chromatic number obtained from the graph (Cn ⊙ Sm) is different from the graph (Sm ⊙ Cn). The chromatic number from the corona operation on the graph (Sm ⊙ Cn) is divided into 2, namely: χS_m⊙C_n = 3 for every odd n, and χS_m⊙C_n = 4 for every even n, m ≥ 3, n ≥ 4, {m, n ∈ N}.

Abstract

Labeling is a one-to-one mapping that maps each element of a graph to Positive numbers called labels. One of its kind is edge-magic total labeling. Under special conditions, the results set of labeled graphs whose subsets are labeled and positioned, which builds the same graph as the labeling, is called the critical set. To obtain the critical set of a graph we must know the type of graph. In this study is a star graph. This study aims to determine the critical set in star graphs. The star graph used is the K1.5 star graph using center points 1, n + 1 and 2n + 1. The research results show that by labeling the total magic side of the K1.5 star graph with center point λ(c) = 1, the magic number k=14 is obtained. The possible critical set of K1.5 graphs is 120. In the K1.5 Star Graph with center point λ(c) = n+ 1, the magic number k=18 is obtained. The possible critical set of K1.5 graphs is 120. In the K1.5 Star Graph with center point λ(c) = 2n + 1, the magic number k=22 is obtained. The possible critical set of K1.5 graphs is 120.

Abstract

The rapid development of digital technology has positioned social media, particularly Instagram, as a strategic channel for brands to conduct digital marketing and brand activation. This quantitative survey research aims to analyze the influence of Instagram content appeal (X) on the audience's interest in participating in the Marina Beauty Journey (Y) program. The study collected data from 100 female followers of the @sahabatmarina account, aged 15-25, who had been exposed to MBJ promotional content. Data analysis utilized simple linear regression. The descriptive analysis results showed that the appeal of @sahabatmarina’s content was perceived as Very High (Mean: 4.41), with Visual and Emotional indicators being the most dominant (Mean: 4.50), reflecting the effectiveness of aesthetic visuals and self-empowerment messaging. The audience's interest in joining the program was also categorized as Very High (Mean: 4.23), primarily demonstrated through the Interaction indicator (Mean: 4.33). The regression analysis confirmed a positive and significant influence of content appeal on audience interest, as indicated by a significance value of p<0.001 and a positive coefficient (beta = 0.622). The coefficient of determination (R2) indicated that content appeal contributed 41.0% to the formation of audience interest, while the remaining 59.0% was influenced by other external factors. In conclusion, the brand's digital content strategy, emphasizing strong visual and emotional connection, is highly effective in driving audience engagement and stimulating participation in its brand activation programs.

Abstract

This study aims to analyze the relationship between online shopping activities and personal financial management among university students in Indonesia. The background of this research lies in the increasing digitalization of daily consumption, which has encouraged students to engage more actively in e-commerce transactions. Using a quantitative correlational design, data were collected from 100 undergraduate students through an online questionnaire based on Likert-scale indicators. The independent variables consist of buyer characteristics (age, gender, and income sources) and online shopping activities (frequency, spending amount, and shopping motivation). Meanwhile, personal financial management is measured through financial planning and spending control. The findings show that students demonstrate very high levels of online shopping activity and acknowledge the strong influence of demographic factors on their consumption behavior. Descriptive analysis also indicates high scores for financial planning and spending control, although intensive online shopping remains a potential risk to financial stability. The implications of this study highlight the need to strengthen financial literacy among students to help them develop healthier budgeting habits and reduce impulsive buying driven by digital platforms. This research is expected to contribute to the understanding of digital consumer behavior and support the development of financial education programs for young adults.
