The purpose of this service activity is to reduce the impact of mercury on small-scale gold mining communities through training and coaching activities in Sekotong village. The Sekotong region, West Lombok Regency is an area rich in potential gold resources with the potential to mine 1,596 tons of gold and can be mined for decades. This potential has been exploited by the community by traditional gold mining. The gold mining area in Sekotong is spread over 3 locations, namely Buwun Mas, Kerato and Pelangan involving 5000 traditional miners. Gold processing carried out in the community is by using amalgamation and cyanidation methods. The technology provided in this service activity is by eliminating the use of mercury in gold processing, reducing the use of cyanide, training and coaching on appropriate standard operating procedures in handling mercury and cyanide, and processing cyanide before it is discharged into the environment. The result of this community service activity is that with the application of this technology, the environment and traditional gold miners become safer and healthier.

Obesity can cause chronic oxidative stress. Oxidative stress occurs when the formation of free radicals is greatly increased or the protective antioxidant mechanisms are disrupted. Previous studies have concluded that there is a relationship between oxidative stress and excess body weight and obesity. One of the products of oxidative stress is malondialdehyde (MDA). This study aims to determine the correlation between malondialdehyde (MDA) levels and body mass index (BMI), waist circumference (LP), and body fat percentage. The subjects were 55 students of the Medical Education Study Program, Faculty of Medicine, University of Mataram, class of 2021. The BMI variable was calculated by dividing body weight (kg) by the square of height (m), waist circumference was measured using a tape measure (cm), and body fat percentage measured by body composition monitor (%). Serum MDA levels were measured using the ELISA method. Data were analyzed statistically with the Spearman correlation test. The results showed that the average MDA level in subjects with overweight and obesity was higher than normal, however there was no significant correlation between body mass index, waist circumference, and body fat percentage with MDA levels, with each significance value :p=0.230; p=0.276; and p=0.666. Body mass index, waist circumference, and body fat percentage cannot be ruled out as risk factors for oxidative stress.

Background: Patients suffering from coronary heart disease can experience psychological changes as well as quality of life. This study aims to determine the quality of life of patients with coronary heart disease post heart attack. Methods: A total of 30 patients with coronary heart disease after diagnosed STEMI, NSTEMI, or unstable angina  for less than one year and had never been diagnosed with a mental disorder. Quality of life was measured by the Indonesian version of the SF-36 Health Survey instrument. Unpaired t-test and Mann Whitney test was conducted to analyze the differences the quality of life based on gender. Results: As many as 36.7% of subjects stated that the current condition was somewhat worse than one year ago. Subjects who stated the same or better were 56.6%. Men have a higher quality of life than women, although it is not statistically significant (p> 0.05). Emotional well-being is the dimension that has the highest average (75.1 ± 17.3) in both the male group (74.8 ± 17.7) and the female group (77.3 ± 16.7). Role limitations due to emotional problems have the lowest score (18.8 ± 33.5) followed by role limitations due to physical problems (20.0 ± 29.7). Conclusion: Patients with coronary heart disease after the attack have the perception that there are limited roles both due to emotional and physical problems. There was no significant difference between the quality of life of coronary heart disease sufferers after the attack of the male and female groups.

Stenosis katup mitral merupakan morbiditas yang masih banyak terjadi di negara berkembang termasuk di Indonesia. Stenosis mitral yang untuk selanjutnya kita sebut sebagai mitral stenosis (MS) merupakan salah satu implikasi dari penyakit jantung rematik. Tanpa pengenalan diagnosis sejak dini dan tatalaksana yang adekuat, stenosis katup mitral akan menyebabkan gagal jantung. Ketika gagal jantung telah terjadi maka morbiditas dan mortalitas pada pasien akan semakin meningkat. Penegakan diagnosis lebih dini akan membantu kita untuk memberikan tatalaksana yang optimal dan mencegah pasien jatuh dalam sindroma gagal jantung Kata kunci: Ekokardiografi, Diagnosis, Stenosis Mitral

Pemahaman revalensi gagal jantung pada usia lanjut merupakan dasar dalam menentukan kebijakan dari stakeholder terkait dengan beban ekonomi negara yang besar dalam penatalaksanaan gagal jantung kronik khususnya pada populasi usia lanjut. Selain itu data epidemiologi gagal jantung kronik tersebut dapat digunakan sebagai pertimbangan klinisi dalam menentukan strategi yang tepat dalam penatalaksanan gagal jantung kronik pada populasi ini. Karena telah kita ketahui bahwa pasien usia lanjut dengan gagal jantung tidak hanya jantungnya yang harus menjadi fokus kita. Komorbid penyakit lain, perubahan fisiologis tubuh, tatacara minum obat merupakan faktor-faktor yang harus menjadi perhatian kita. Kata kunci: Epidemiologi, Gagal jantung kronik, usia lanjut.
