Abstract

The North Sumatra Basin is one of the major sedimentary basins in Indonesia with significant hydrocarbon potential. However, exploration in this region faces challenges due to overpressure, which can increase operational risks such as blowouts. This study aims to analyze pore pressure and overpressure formation mechanisms in Well Al using the Eaton method and a crossplot approach between sonic and density data. The analysis results indicate that the top overpressure is identified at a depth of 8,500 ft in the Keutapang Formation and continues into the Baong, Bampo, and Parapat Formations. Wireline log evaluation indicates anomalies in the sonic, neutron, and density logs, which are consistent with disequilibrium compaction patterns. The Dutta crossplot results also confirm the dominance of smectite minerals without transformation into illite, reinforcing that the primary overpressure mechanism is loading due to disequilibrium compaction. Accurate pore pressure modeling is necessary to improve drilling safety and efficiency in this area.

Abstract

The increasing demand for beauty treatments has made customer satisfaction a critical factor in determining the success of beauty clinics. This study aims to evaluate patient satisfaction with the services provided by Klinik Utama Ramanathan in Medan. Using a quantitative approach with survey methods, data was collected from 60 respondents who had received treatments at the clinic. The analysis was based on five dimensions of service quality: tangible, reliability, responsiveness, assurance, and empathy. Results indicate that the overall patient satisfaction level is high, with the assurance dimension receiving the highest rating (4.4) and responsiveness scoring the lowest (4.1). Regression analysis revealed that assurance had the most significant impact on patient satisfaction, followed by tangible aspects, empathy, reliability, and responsiveness. Although the clinic performs well in service quality, improvements in responsiveness, such as faster response times and enhanced customer interaction, could further enhance patient satisfaction. The study highlights the importance of continuous service quality improvements in maintaining competitiveness in the beauty clinic industry.

Abstract

This study examines the impact of the problem-based learning model and differentiated approach on the learning outcomes of natural and social science students in grade V at SD Mahesa Jenar Cluster, Ambarawa District, Semarang Regency. Interviews and observations revealed that students learning outcomes remain low due to monotonous, teacher-centered learning models that do not address student’s needs. The problem-based learning model enhances critical thinking, while the differentiated approach caters to individual students needs. Both methods are student-centered, aiding learners in understanding concepts and applying them in real life. Employing a quantitative ex post facto design, data were collected through questionnaires distributed to students. The variables studied include natural and social science learning outcomes (Y), problem-based learning models (X1), and differentiated approaches (X2). Data were tested for normality, linearity, multicollinearity, and heteroscedasticity before analysis. Hypothesis testing utilized simple correlation, multiple correlation, simple regression, multiple regression, determination tests, and F-tests. Results indicated that the problem-based learning model influenced learning outcomes by 4% (R square = 0.040), while the differentiated approach contributed 3.7% (R square = 0.037). combined, these approaches had a joint influence of 6.3% (R square = 0.063), positively affecting students learning outcomes in grade V at SD Mahesa Jenar Cluster, Ambarawa District, Semarang Regency.

Abstract

Despite recent improvements in health indicators, ensuring affordable, quality healthcare for the elderly in Riau Province remains challenging. This study examines personal experiences accessing healthcare services, costs, barriers, and strategies to develop more effective solutions for elderly welfare. We conducted a qualitative phenomenological study with 20 seniors in Riau Province (November-December 2024) with equal gender representation. Experienced interviewers gathered information about healthcare seeking, accessibility, affordability, and strategies. Data were analyzed using thematic analysis. Results revealed unsatisfactory health conditions among elderly populations, with many suffering from benign tumors, chronic kidney disease, persistent pain, and gastric ulcers. Most participants had multiple non-communicable diseases, particularly diabetes and hypertension. The elderly faced significant obstacles accessing both government and private healthcare, including inadequate facilities, long wait times, complicated referral systems, and limited medication and medical personnel availability. Financial constraints presented major barriers, especially for private services with high costs. Limited understanding of procedures and additional expenses further complicated access. Transportation issues and lack of awareness about available services highlighted the need for targeted interventions to improve health outcomes in this demographic. System improvements and service enhancements are necessary for optimal healthcare access. Policymakers and elderly care providers must prioritize elderly-friendly healthcare infrastructure with affordable care costs to improve health conditions among senior citizens in Riau Province.
