Abstract

Reading skills refer to an individual's ability to read text accurately and understand its meaning. This study aims to analyze the relationship between the intensity of Voice Note feature use on the WhatsApp application with reading skill indicators, which include articulation, intonation, phrases, and punctuation. In addition, this study also evaluates the effect of giving reading recording assignments via WhatsApp Voice Notes on the reading skills of second-grade students. Using a quantitative approach with a one-shot case study pre-experimental design, this study involved 28 second-grade students at Cirengit Elementary School. Data were obtained through reading aloud tests and WhatsApp Voice Note recordings, then analyzed using descriptive statistics (mean, percentage, and standard deviation) and inferential statistics (Shapiro-Wilk normality test, Pearson and Spearman's Rho correlation, linearity test, and simple linear regression). The results of the analysis indicate that the intensity of WhatsApp Voice Note use has a strong relationship with intonation, phrases, and punctuation use (high category), and a moderate relationship with articulation. Furthermore, the regression results showed that providing reading recording assignments via WhatsApp Voice Notes contributed 49% to improving students' reading skills, with an R-square value of 0.488. This finding confirms that the use of WhatsApp Voice Notes is effective in supporting the improvement of students' reading skills, although the impact varies across indicators.

Abstract

As a form of responsibility toward transformation in the field of education, schools must have the capacity to realize and develop students’ character by strengthening the role of religion in learning activities. Religious activities not only play a crucial role in shaping student character but also foster habits of discipline, responsibility, and the development of good personal values. Discipline, in turn, leads to orderly learning, which becomes a motivation for academic achievement. A visionary principal holds a strategic role in encouraging students to develop religious character through various religious activities conducted by the school, including extracurricular, intramural, and co-curricular programs. This study employs a qualitative method with a phenomenological design. Data were collected through interviews, observations, and documentation. The data analysis technique follows the Miles and Huberman model, including data display, data reduction, and data verification (drawing conclusions). Visionary leadership in developing Islamic values at SDN 1 Durenan, Trenggalek, is implemented massively through religious activities. The principal plays a central role as a leader of change, policy-maker, and coordinator in improving students’ academic achievement. As agents of change, educators and school staff are responsible for implementing and evaluating religious activities in the school environment. Students, as the primary focus of academic achievement improvement, receive full attention from both the principal and the teaching staff.

Abstract

This study aims to evaluate the archive management system implemented at PT Surabaya Industrial Estate Rungkut (PT SIER), a state-owned enterprise managing industrial areas in Indonesia. The research employed a qualitative descriptive approach involving field observation, interviews with archive personnel, and documentation analysis. Findings indicate that PT SIER’s current archive management system is predominantly manual, lacks integration with digital technology, and suffers from unstructured classification practices. Major internal constraints include limited qualified human resources and the absence of standardized archival procedures. External constraints involve inadequate storage facilities, leading to disorganized document placement and increased risk of physical damage. The study also found that document retrieval is inefficient due to reliance on a single archive officer and the absence of systematic indexing. Based on these findings, the study recommends the implementation of an integrated digital archival system, the development of Standard Operating Procedures (SOPs), and regular training for employees to enhance document classification and indexing. These measures are expected to improve the efficiency and reliability of PT SIER’s archival practices.

Abstract

Traffic congestion frequently occurs on MT Haryono Street in Balikpapan. Changes in travel patterns, population growth, and infrastructure development have a significant impact on the traffic conditions on this road. Effective congestion management requires a thorough understanding of traffic volume, speed, and density to develop appropriate strategies. This study aims to analyze the relationship between traffic volume, speed, and density using the Greenshield, Greenberg, and Underwood models, and to identify the model that best represents the traffic conditions. This quantitative research involved a field survey over a 400–meter segment of the road to determine the traffic volume, speed, and density. The collected data on volume, speed, and density were then analyzed using the Greenshield, Greenberg, and Underwood models. Based on the analysis of the relationship between traffic volume, speed, and density using the Greenshield, Greenberg, and Underwood models, the following primary conclusions are drawn. These models illustrate different relationships: Greenshield as linear, Greenberg as logarithmic, and Underwood as exponential. The analysis reveals a decline in speed with increasing volume and density, with Greenberg's model predicting higher speeds at low densities; however, this is less realistic. In contrast, the Greenshield and Underwood models more closely align with actual conditions. Among the models, Greenshield has the highest coefficient of determination (r² = 0.775), making it the most accurate in depicting this relationship.

Abstract

This research aims to analyze the marketing strategies implemented by the MSME Adhiya Fashion to enhance competitiveness and expand market reach through social media. The study focuses on the application of the marketing mix (4P), consisting of Product, Price, Place, and Promotion. A descriptive qualitative approach was used, with data collected through observation, interviews, documentation, and questionnaires. The results indicate that social media platforms such as Instagram serve as the primary channel for Adhiya Fashion to showcase Products, engage with customers, and build brand awareness. Product strategies involving various hijab designs and appealing visual content have proven effective in attracting the attention of young consumers. Pricing strategies are adjusted to match the purchasing power of the target market, while distribution is carried out through online ordering systems. Promotional efforts include interactive content, special discounts, and the use of Digital trends. Despite the effectiveness of social media strategies, limitations in audience targeting and the minimal use of paid advertising features remain challenges. This research concludes that the integration of Digital marketing strategies based on the 4P framework can significantly contribute to the growth of MSMEs in the modest fashion sector.
