Background: Coronary artery disease (CAD) is the main cause of death in the world. In this study we assessed the ankle-brachial index (ABI) as a screening tool for CAD. Methods: Between 2020 and 2023, a large population-based cross-sectional study was conducted on 4,207 new patients referred to Harapan Kita Hospital. The patients underwent selective coronary angiography via a radial artery approach. ABI was calculated for all patients. Researchers compared ABI with coronary angiography results to determine the specificity and sensitivity of ABI as a screening tool. Results: Abnormal ABI was significantly more common in patients with proven severe CAD (893, 54.8%) than in patients with proven mild CAD (33, 4.7%) or no CAD (94, 5.3% ). The specificity of the ABI was 95.3% and the sensitivity was 54.8%. ABI is associated with risk factors such as smoking, male gender, hypertension, diabetes mellitus and dyslipidemia. Conclusion: ABI can be used as a screening test to prevent CAD with a specificity of 95.3%. We need to consider risk factors other than ABI to improve screening sensitivity. Multidimensional scoring systems should consider risk factors and other noninvasive tests in addition to ABI to develop an ideal screening system for CAD

State Vocational High School (SMK) 2 Kuripan, is located on the border of two districts, namely West Lombok and Central Lombok with a fairly large number of students where they come from various regions with varied backgrounds and characters and it is very possible that this will happen. violations by students. Violations that often occur are indiscipline, students are late for class, truant, jumping fences, smoking, fighting and so on. For this reason, it is deemed necessary to have a system used to assist in making decisions in determining sanctions for such violations. This study aims to design a system that can help facilitate BK teachers in determining sanctions to students using the AHP (Analytic Hierarchy Process) and SAW (Simple Additive Weight) methods. In designing the system, it has several assessment criteria with weighted points and priorities for each alternative. Every violation committed by students will be processed quickly accompanied by sanctions and predetermined actions. This process can assist BK teachers in determining sanctions for students and making reports to the waka of students and the principal of SMKN 2 Kuripan.

Lifestyle is an important factor that influences people's lives. This research method uses descriptive analytics with a cross sectional approach. The total population in this study was all patients who experienced hypertension at the Haji Makassar Regional General Hospital, totaling 316 people. In this research, the sample used was purposive sampling. The sample in this study was 47 patients who experienced hypertension at the Haji Makassar Regional General Hospital. The instruments used in this research were questionnaires and observations. The research results obtained a value of ρ=0.008<0.05, this means that there is a relationship between diet and hypertension in inpatients at the Haji Makassar District Hospital. Based on the results of data analysis, it was obtained that the value ρ=0.003<0.05 means that there is a relationship between smoking and hypertension in inpatients at the Haji Makassar Regional Hospital. This research is used as input for health workers who carry out their duties in providing nursing care, especially in cases of hypertension.
