Abstract

The increasingly intense global laptop industry competition drives every  brand to rely not only on technical specifications, but also on building brand personality and product quality that can influence consumer purchase decisions. HP, as one of the world's largest laptop brands, still faces competitive market dynamics. Inconsistencies in previous research findings, serve as the basis for this study. This study aimed to determine and analyze the effect of brand personality and product quality on HP laptop purchase decisions among students in Malang City, both partially and simultaneously.   This study employed a quantitative approach with a survey method. The sample consisted of 100 respondents determined using the Cochran formula and  purposive sampling technique. The respondents were active students from three  state universities in Malang City who had purchased and used HP laptops as their primary device to support academic activities. Data were collected through a Likert scale questionnaire and analyzed using validity tests, reliability tests, classical assumption tests, multiple linear regression, the coefficient of determination, t-tests, and F-tests with the assistance of IBM SPSS Statistics 25.  The results indicated that brand personality had a positive and significant partial effect on purchase decisions. Meanwhile, product quality also had a positive and significant partial effect on purchase decisions. Simultaneously, brand personality and product quality together had a significant effect on purchase decisions. Product quality was found to be the most dominant variable compared to brand personality. This indicates that purchase decisions for HP laptops can be shaped through the strengthening of positive brand personality and product quality that meets student expectations.

Abstract

Dental and oral hygiene is an important factor in preventing caries and periodontal disease. One of the efforts that can be made to control plaque is the use of natural mouthwashes such as red betel leaves (Piper crocatum Ruiz & Pav.) which contain antibacterial compounds. This study aims to determine the effect of gargling using red betel leaf boiled water on the decrease in the Personal Hygiene Performance Modified (PHP-M) index in the people of Sawang Village, Sawang District, North Aceh Regency. This study uses a quasi experimental design with a nonequivalent control group design. The research sample amounted to 68 respondents aged 12–15 years who were divided into an experimental group (34 respondents) and a control group (34 respondents). The experimental group gargled using 20 ml of red betel leaf boiled water for 30 seconds twice a day for 7 days, while the control group gargled using water. Measurements of the PHP-M index were carried out before and after the intervention. Data analysis was conducted using Paired T-Test and Independent T-Test. The results showed that the average PHP-M index in the experimental group decreased from 39.29 to 22.35 with a decrease of 16.94 points and a p<0.001 value. In the control group, the average PHP-M index decreased from 36.97 to 36.62 with a difference of 0.35 points and a p=0.564 value. The Independent T-Test showed that the average post-test score of the experimental group was lower than that of the control group with p<0.001. It can be concluded that gargling using red betel leaf decoction has a significant effect on the reduction of the PHP-M index and may be used as an alternative natural mouthwash.

Abstract

The AHP modeling method in this study was conducted by weighting six main technical criteria: Voltage Drop Magnitude (C1), Voltage Drop Percentage (C2), Load Magnitude (C3), Distance from Source (C4), Average Current (C5), and Line Impedance (C6). The analysis results show that the most dominant factor influencing voltage drop is voltage quality, with the highest criteria weights being Voltage Drop Percentage (35.7%) and Voltage Drop Magnitude (28.3%). Based on the global score index calculation, the classification of four alternative loads is as follows: The FJM Office (A1) ranks first with a score of 50.9% and is interpreted as an "Influential" load due to its voltage drop of 5.35%, which technically exceeds the standard operational limit. The AJG Office (A2) scored 23.6%, interpreted as "Moderately Influential," while the Workshop (A4) and the Security Post Office (A3) scored 16.9% and 8.2%, respectively, interpreted as "Less Influential”.

Abstract

Digital inequality remains a challenge in ensuring equitable access to and use of information and communication technology across regions in Indonesia. This study aimed to map digital inequality among 38 Indonesian provinces in 2024 using the K-Means clustering algorithm. Secondary data obtained from Statistics Indonesia (BPS) were analyzed using three indicators: the percentage of the population accessing the internet, owning or controlling mobile phones, and using computers. The data were standardized using Z-score transformation, while the optimal number of clusters was evaluated using the Elbow Method and Silhouette Score. The results showed that two clusters provided the optimal configuration, with a Silhouette Score of 0.7457. Cluster 0 consisted of 36 provinces, with average internet access, mobile phone ownership or control, and computer use of 70.84%, 69.08%, and 12.09%, respectively. Cluster 1 consisted of Central Papua and Highland Papua, with substantially lower averages of 17.74%, 24.73%, and 2.98%, respectively. Principal Component Analysis further supported the clustering structure, with two principal components explaining 98.89% of the total variance. These findings demonstrate a pronounced multidimensional digital gap and highlight the need for more targeted digital development policies in disadvantaged regions.

Abstract

This study aims to analyze the factors influencing Behavioral Intention to Use QRIS among culinary micro, small, and medium enterprises (MSMEs) in DKI Jakarta using the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model extended with Perceived Security and Perceived Trust variables. This study employed a quantitative approach with a survey method involving 214 MSME respondents who have used QRIS. Data were analyzed using Structural Equation Modeling-Partial Least Squares (SEM-PLS). The results indicate that Performance Expectancy, Effort Expectancy, Price Value, Perceived Security, and Perceived Trust have a positive and significant effect on Behavioral Intention to Use QRIS, with Perceived Trust being the most influential factor. Meanwhile, Social Influence was found to have no significant effect. The R² value of 0.578 indicates that the model explains 57.8% of the variation in behavioral intention to use QRIS. These findings suggest that increasing QRIS adoption among MSMEs should be supported by providing beneficial and easy-to-use services, costs commensurate with benefits, robust security systems, and efforts to build MSME owners' trust in QRIS as a digital payment method. This study contributes to the development of UTAUT2 literature by extending the model in the context of digital payment adoption in the MSME sector.
