Abstract

Mathematics is a vital tool for solving problems in everyday life. For pharmacy students, it is the basis for formulating pharmaceutical preparations, calculating maximum doses, and performing dilutions. In calculations, students must understand the problem, plan the solution, carry out the steps, and ensure accuracy, which reflects problem-solving ability. There are four books with ISBNs, 3 discussing only mathematical concepts and one focusing on pharmaceutical calculations, but none combining both. Therefore, it is urgent to develop contextual, problem-solving-based textbooks to support pharmaceutical mathematics learning. This study aims to create a pharmaceutical mathematics textbook that strengthens problem-solving skills, particularly in measurement units and concentration statements. This study employed the ADDIE development model with 95 first-year pharmacy diploma students as respondents, and data were collected through a questionnaire. The results of the validity test, as evaluated by material and media experts, averaged 85.98% (considered very valid), while the feasibility test, conducted by lecturers and students, averaged 84.55% (also considered very feasible). It can be concluded that the developed textbook is valid, practical and effective for use in diploma and undergraduate pharmacy programs. The results can also guide the development of other chapters in pharmaceutical mathematics and help evaluate teaching materials to improve problem-solving skills at STIKes IKIFA.

Abstract

Hypertension is one of the Non-Communicable Diseases (NCD) that can lead to serious conditions such as heart disease, stroke, or death. It can’t be cured; patients need lifelong medication. That is why adherence to treatment is a must for hypertensive patients. This study aims to investigate the relationship between sociodemographic, clinical factors and medication adherence among hypertension patients at a private hospital in Jakarta. This study is a pilot study using a cross-sectional method with 97 hypertensive patients. Patient medication adherence was assessed using the validated ProMAS questionnaire. The patients’ scores were then divided into two categories: good and poor adherence, based on 80% of the total score. Binary logistic regression was used to identify factors associated with adherence, with model selection based on the Akaike Information Criterion (AIC). The Pseudo-R² by Nagelkerke was used in this study for the model's goodness-of-fit, with a value of 0.232 (23.2%). The results showed that 74 (76.3%) patients had poor adherence, while 23 (23.7%) patients had good adherence. Among all the socioeconomic and clinical variables, only the education variables showed a significant correlation with medication adherence. Patients with college and junior high school education levels were more likely to be compliant compared to those with senior high school education (OR = 10.42 and OR = 8.75, respectively). The results of this study show that medication adherence among hypertensive patients in private hospitals varies based on patients’ backgrounds. The findings highlight the need for hospital policies, such as health education programs based on the patients’ education levels, in order to improve the effectiveness of long-term hypertension management.
