Pulmonary function disorders are commonly underdiagnosed health issues, especially in urban areas with high air pollution and prevalent smoking habits. Early detection through spirometry plays a crucial role in the promotion and prevention of respiratory diseases such as asthma and Chronic Obstructive Pulmonary Disease (COPD). However, public awareness and access to spirometry remain limited, including in the Tanjung Duren Selatan subdistrict of West Jakarta. This community service program was conducted using the Plan-Do-Check-Act (PDCA) cycle management approach. The target population consisted of productive-age residents willing to participate in health education and lung function screening. Spirometry examinations were conducted alongside interactive counseling about respiratory health and risk factors. Evaluation was carried out through spirometry results and participant satisfaction surveys. A total of 92 participants took part in the activity, consisting of 70 females (76.1%) and 22 males (23.9%), with a mean age of 43.78 years (SD ±12.93). The average Vital Capacity (VC) was 2.26 L, Forced Vital Capacity (FVC) was 2.13 L, and Forced Expiratory Volume in 1 Second (FEV1) was 1.95 L. The mean FEV1/FVC ratio was 107.12%, with 100% of participants showing normal lung function. This activity demonstrates that spirometry is an effective tool for monitoring lung function and increasing community awareness. Similar screening initiatives should be expanded to support early detection of respiratory disorders at the community level.

Type 2 diabetes mellitus is a chronic metabolic disease that is common in the elderly and has a major impact on quality of life, especially through risk complications such as impaired vision, heart disease, kidney failure, and amputation. The elderly are often unaware of the early symptoms of diabetes because complaints are considered part of the aging process, such as fatigue or frequent urination. The Community Service Program (PKM) at Panti Werdha Hana aims to increase awareness of the elderly about the importance of early detection of diabetes through fasting blood sugar screening activities. This activity uses the Plan-Do-Check-Act (PDCA) approach which includes checking blood sugar levels with the Point-of-Care Testing (POCT) tool and educational counseling on risk factors and prevention of diabetes. The results showed that out of 76 participants, 8 people (10.53%) were identified as having diabetes, 9 people (11.84%) had prediabetes, and the rest had normal blood sugar levels. Early detection through screening has proven to be an important step in preventing diabetes progression and severe complications, as well as supporting the improvement of the quality of life of the elderly through timely interventions and ongoing education.

Uric acid (UA) is a waste product formed when the body breaks down purines, which are natural compounds found in the body and can be found in various types of foods such as alcohol, shellfish, and liver. Hyperuricemia is caused by increased uric acid production, decreased excretion, or a combination of both processes. Most people with hyperuricemia are asymptomatic (85% to 90%), but increased levels of uric acid in the blood or urine can cause gout or nephrolithiasis. Hyperuricemia and hyperuricosuria are also associated with other disorders such as metabolic syndrome, diabetes mellitus, cardiovascular disease, hypertension, atherosclerosis, obesity, and chronic kidney disease. The Community Service (PKM) activity held in Grogol Village, West Jakarta, aims to increase awareness of the elderly community regarding the importance of early detection of hyperuricemia. This program uses the Plan-Do-Check-Act (PDCA) approach, starting from planning uric acid level examinations and compiling educational materials, followed by implementing interactive screening and counseling, evaluating results, and following up in the form of medical referrals for participants with abnormal results. Of the 71 participants involved, only 1 person had uric acid levels above normal. Through education on low-purine diets, the importance of hydration, and physical exercise, this activity is expected to be able to reduce the incidence of hyperuricemia and its complications, as well as support the realization of a healthier elderly community that is aware of its metabolic health.

Urinary tract infections (UTIs) are common health problems among the elderly and can significantly reduce quality of life due to complications such as systemic infections, kidney disorders, and recurrent infections. Older adults often do not recognize early symptoms of UTIs, as the manifestations are atypical and frequently mistaken as part of the normal aging process. The Community Service Program (PKM) conducted at Panti Werdha Hana aimed to increase elderly awareness of the importance of early UTI detection through urinalysis as a screening method. This activity was carried out using the Plan-Do-Check-Act (PDCA) approach, which included urine testing for leukocyte esterase, nitrites, and protein, as well as educational sessions on UTI risk factors and prevention strategies. Among the 76 participants examined, 2 individuals (3.08%) tested positive for leukocyte esterase and 1 individual (1.54%) tested positive for nitrites, indicating potential infection. These findings suggest that simple urin tests can serve as an effective initial step in detecting UTIs early and promoting timely interventions to maintain urinary tract health and improve the overall quality of life in the elderly.
