Hypercholesterolemia is a term when total cholesterol, LDL, and triglyceride levels increase, while HDL decreases. The causes of high cholesterol today are poor diet, suboptimal physical activity, excessive caffeine consumption, and uncontrolled body weight. The purpose of this community service is to increase public knowledge about hypercholesterolemia, including its causes, symptoms, and treatment. In addition, cholesterol examinations were also carried out on 25 residents using the POCT method.

Biosensors are analytical devices that combine biological sensing elements with physicochemical detectors to provide rapid, accurate, and cost-effective solutions for medical diagnostics. Globally, these devices have revolutionized the detection and monitoring of diseases, significantly impacting patient outcomes. In Indonesia, the adoption and development of biosensor technology have accelerated over the past decade, particularly in response to the growing healthcare needs and the government's push for technological innovation. This study aims to review and analyze the development and application of biosensors in Indonesia medical diagnostics sector between 2014 and 2024. The research focuses on identifying key technological advancements, the integration of biosensors into healthcare, the challenges faced in their development and deployment, and the prospects for future growth. The study employs a comprehensive literature review and analysis of scientific publications, industry reports, and government documents related to biosensor technology in Indonesia. The review covers the evolution of biosensing materials, point-of-care testing applications, integration with digital health technologies, and regulatory frameworks. Data were synthesized to provide a detailed overview of the current state of biosensor technology and its impact on medical diagnostics in Indonesia. The findings indicate significant advancements in biosensor technology, particularly in the development of novel nanomaterials, the integration of biosensors with mobile health (mHealth) platforms, and the expansion of point-of-care testing (POCT) for infectious diseases. However, the sector faces challenges, including technological limitations, regulatory hurdles, and economic constraints, which have slowed the widespread adoption of biosensors in clinical settings. Despite these challenges, the future of biosensors in Indonesia appears promising, with continued investment and innovation expected to drive further advancements in this field.

Hyperuricemia is defined as increased levels of uric acid in the blood, this can result in gout which is characterized by pain and redness in the joints. Currently, increased uric acid levels are often caused by excessive consumption of red meat including offal, being overweight, consuming foods high in cholesterol, and rarely exercising. The purpose of this counseling and examination of uric acid levels is to increase public knowledge about gout and gout screening by conducting uric acid examinations using POCT. The implementation method used is direct delivery of material related to gout, symptoms, and prevention including screening of uric acid examinations using the POCT method.

Uric acid is an end product of purine metabolism that can crystallize at high concentrations, causing gout and other related conditions. This study aims to describe the proportion and risk factors for hyperuricemia in the productive age population. This descriptive research was conducted in March 2024 at Kalam Kudus II High School, Duri Kosambi Village, using purposive sampling techniques. The sample consisted of 74 respondents aged 18-64 years. Data collection includes demographic characteristics and uric acid levels using the Point Of Care Testing (POCT) tool. The results showed that 67 respondents (90.5%) had normal uric acid levels, while 7 respondents (9.5%) had hyperuricemia. Identified risk factors include a high-purine diet, obesity, metabolic syndrome, certain medical conditions, and genetic factors. The results of this research are the importance of changing diet, weight loss, adequate hydration, and the use of medication in managing uric acid levels. Health education has proven important for improving patient compliance with diet and medication, as well as preventing complications. Therefore, it is necessary to develop comprehensive educational programs and further research to improve the treatment of hyperuricemia.
