Hubungan Tingkat Pengetahuan Dan Sikap Pasien Terhadap Penyakit Ispa Dan Pengobatannya Di Klinik X Padang

2025-07-22T07:53:09+00:00

Infeksi Saluran Pernapasan Akut (ISPA) adalah penyakit pada saluran pernapasan atas dan bawah yang disebabkan oleh virus atau bakteri. Faktor penyebab utamanya meliputi polusi udara, sanitasi lingkungan yang buruk, serta kurangnya pengetahuan dan pola hidup tidak sehat. Penelitian ini bertujuan mengetahui tingkat pengetahuan dan sikap pasien terhadap ISPA dan pengobatannya, serta hubungannya di Klinik x Padang. Penelitian ini bersifat deskriptif analitik dengan teknik accidental sampling dan menggunakan kuesioner, dianalisis dengan uji chi-square. Hasil menunjukkan mayoritas pasien memiliki pengetahuan sangat baik (72,4%), diikuti baik (21,4%) dan kurang baik (6,1%). Sementara itu, sikap pasien sebagian besar tergolong baik (64,3%) dan sangat baik (35,7%). Namun, uji statistik menunjukkan tidak terdapat hubungan signifikan antara tingkat pengetahuan dan sikap terhadap ISPA. Persentase tertinggi ditemukan pada kategori pengetahuan sangat baik (48 responden/67,6%) dan sikap baik (48 responden/76,2%). Meskipun pengetahuan tinggi, hal ini tidak selalu diikuti oleh sikap yang sebanding. Faktor lain kemungkinan memengaruhi pembentukan sikap pasien terhadap ISPA dan pengobatannya.Abstract ditulis dalam bahasa Inggris dan bahasa Indonesia (kecuali artikel yang ditulis dalam bahasa Inggris) yang berisikan isu-isu pokok, tujuan penelitian, metode/pendekatan dan hasil penelitian..

Perancangan Decision Support System Berbasis Website Untuk Pengawasan Risiko Pada Institusi Pengawas Tenaga Nuklir

2025-08-04T14:11:03+00:00

Safety risk surveillance at nuclear facilities is an important element in ensuring the protection of workers, the public, and the environment from radiation hazards. The Nuclear Power Supervisory Institution manages large data related to nuclear safety risk surveillance. However, this very large and diverse volume of data causes difficulties in adequate processing and analysis, thus hampering the speed and accuracy of supervisory decision making. The main obstacle faced is data management that is still manual and less integrated so that the risk monitoring process becomes less efficient. Therefore, this research designs a website-based Decision Support System (DSS) with the Analytic Hierarchy Process (AHP) method to assist the decision-making process that is more objective, accurate, and based on risk priorities in nuclear safety. The results showed that the use of the AHP method in DSS was able to provide priority weights for risk criteria in an objective and structured manner. Consistency Ratio (CR) of 0.0066 shows a good level of assessment consistency. This system facilitates data visualization and presents safety risk inspection priority recommendations effectively through an interactive dashboard. The designed DSS is expected to improve the efficiency and effectiveness of nuclear safety risk monitoring at the Nuclear Power Supervisory Institution.

Hypertension is a condition diagnosed when repeated blood pressure measurements show values ≥140/90 mmHg. Long-term treatment is required to control blood pressure, making patient adherence to therapy essential for achieving therapeutic targets. Non-adherence can negatively impact patients’ quality of life, as poor health-related quality of life may limit daily functioning. The Pill Count method and the SF-36 questionnaire were used to assess medication adherence and quality of life. This study aimed to determine the relationship between antihypertensive medication adherence and the quality of life in hypertensive patients. The research was conducted at Lubuk Buaya Public Health Center from February to March 2023. It was a non-experimental analytic study using a cross-sectional method. A total of 90 participants were selected using purposive sampling. The results showed that adherence to antihypertensive medication significantly influenced only certain domains, likely due to most respondents exhibiting good adherence and high awareness, which contributed to a better quality of life. Chi-square analysis revealed a significant relationship between medication adherence and health-related quality of life, particularly in the domains of bodily pain, social functioning, and mental health.

2025-08-18T02:29:21+00:00

Kesehatan gigi dan mulut merupakan bagian penting dari kesehatan secara keseluruhan, namun karies gigi masih menjadi penyakit yang umum diderita oleh masyarakat. Plak gigi adalah penyebab utama masalah kesehatan gigi dan mulut dan pasta gigi berperan penting dalam mengendalikannya. Daun sungkai (Peronema canescens Jack) memiliki berbagai khasiat, termasuk sifat antibakteri. Penelitian ini bertujuan untuk memformulasikan dan mengevaluasi stabilitas pasta gigi yang mengandung ekstrak daun sungkai dengan menggunakan Na-CMC sebagai agen pengikat. Ekstrak daun sungkai dibuat melalui maserasi dengan etanol 96%. Empat formula pasta gigi, termasuk satu kontrol, dibuat dan diuji stabilitas fisiknya (uji homogenitas, pH, tinggi busa, dan organoleptik) selama dua minggu. Hasil pengujian menunjukkan bahwa semua formula homogen dan memiliki pH yang stabil dalam rentang 6,5 hingga 8,0, yang sesuai dengan standar SNI (4,5-10,5). Namun, tidak ada busa yang signifikan yang terbentuk, kemungkinan karena viskositas yang tinggi akibat konsentrasi Na-CMC yang berlebihan. Formula 3, dengan konsentrasi Na-CMC tertinggi, menunjukkan tekstur paling kental dan stabil. Disimpulkan bahwa formulasi pasta gigi ekstrak daun sungkai berhasil dibuat dengan stabil, dan formula 3 adalah yang paling ideal, meskipun busa tidak terbentuk.

Office ergonomics is a branch of ergonomics that covers the entire work environment (workstations) as well as work tools (especially the use of computers and chairs) in offices. In modern office areas, most activities are carried out using a computerized system, so that all working time is carried out in a sitting working position. In essence, a human biomechanically needs to move in activities, not just stand or sit in only one position. Mie Kuning Putri Minang as the research object is located on Jalan Utara II, Seberang Padang, Padang Selatan District, Padang City, West Sumatra. The aim of this research is to improve work posture using the CMDQ (Cornell Musculoskeletal Discomfort Questionnaire) and ROSA (Rapid Office Strain Assessment) methods. ). The results of research using the CMDQ method show that employees complain about the neck, shoulders, arms, back, waist, hips, buttocks, and need immediate improvement. The results of the ROSA calculation show that employee A, employee B, and employee C have a high or dangerous risk, and urgent improvements need to be made. The cause of the high risk experienced is due to the inadequate facilities used, the need to update work facilities according to ergonomic standards in the world of work, and holding good and correct computer office ergonomics training to reduce injuries when using computers.
