Congestive Heart Failure (CHF) adalah salah satu masalah kesehatan yang progresif dengan angka mortalitas maupun morbiditas yang tinggi dan berpotensi terjadi ADRs (adverse drug reactions). Resiko ADRs pada pasien CHF berkaitan dengan regimen obat yang kompleks dan banyaknya komorbiditas pada pasien tersebut. Penelitian ini dilakukan untuk mengukur kausalitas dan menganalisis obat dan jenis ADRs yang paling sering terjadi. Penelitian ini termasuk retrospective study dengan data penelitian yang digunakan adalah data pasien CHF yang menjalani rawat inap RSUD Provinsi NTB dari tahun 2017 sampai 2019. Penilaian kausalitas ADRs menggunnakan skala WHO-UMC. Data pasien CHF yang digunakan dalam penelitian ini sebanyak 325 pasien. Sebanyak 223 pasien (68,6%) tercatat mengalami ADRs dengan hasil penilaian kausalitas menggunakan WHO-UMC antara lain 8 (1,8%) certain, 178 (39,9%) probable/likely, dan 260 (58,3%) possible. Obat yang paling banyak menimbulkan ADRs dengan status kausalitas certain adalah ramipril yang menimbulkan batuk. Kesimpulan: sebagian besar ADRs yang terjadi pada pasien CHF adalah possible dan jenis obat yang paling tinggi menimbulkan ADRs adalah ramipril sehingga penggunaan ramipril perlu lebih diperhatikan karena termasuk highly probable dalam menimbulkan ADRs.Identification of The Causality of ADR (Adverse Drug Reactions) in CHF (Congestive Heart Failure) PatientsAbstractCongestive Heart Failure (CHF) is a progressive health problem with high mortality and morbidity rates and the potential for ADRs (adverse drug reactions). The risk of ADRs in CHF patients is related to the complex drug regimen and the many comorbidities in these patients. This study was conducted to measure causality and analyze the most common drugs and types of ADRs. This study includes a retrospective study with the research data used is data on CHF patients who underwent hospitalization at the NTB Provincial Hospital from 2017 to 2019. The causality assessment of ADRs used the WHO-UMC scale. Data on CHF patients used in this study were 325 patients. A total of 223 patients (68.6%) were recorded to have ADRs with the results of a causality assessment using WHO-UMC including 8 (1.8%) certain, 178 (39.9%) probable/likely, and 260 (58.3%) possible. The drug that causes the most ADRs with certain causality status is ramipril which causes coughing. Conclusion: most of the ADRs that occur in CHF patients are possible and the type of drug that causes the highest ADRs is ramipril so that the use of ramipril needs to be paid more attention because it is highly probable in causing ADRs.

Basic physics experiment textbooks are widely used by lecturers and students in physics courses at universities, but relevant and easy-to-use basic physics experiment textbooks are not yet available. Most of the available books are practical books. The purpose of this study was to determine the stages of developing a basic physics experimental textbook based on pictorial riddles. This type of research is research and development (R&D) research. The research uses the Plomp Model with three stages, namely preliminary research, prototype or development, and assessment. The subjects of this study were students of the Physics Education study program at the University of HKBP Nommensen Pematangsiantar. Data analysis used descriptive quantitative. The results showed that the development value of pictorial riddle-based textbooks had a high level of attractiveness based on the assessment of material/content experts reaching 93.75%. The development value based on pictorial riddle has a high level of attractiveness based on field test assessments reaching 91%. This shows that the development of pictorial riddle-based basic physics experimental textbooks has good quality and is suitable for use to improve student learning outcomes in basic physics experimental subjects.
