Background: Background: Wiloso Hamlet, Gondowangi Village, Wagir Subdistrict, Malang Regency, is predominantly inhabited by informal laborer residents. Occupational health has become a key priority within Indonesia’s primary health care transformation at the Puskesmas (Community Health Center). Purpose: The researcher would like to apply the nursing process to the community health problem in Wiloso Hamlet, Gondowangi Village, Wagir District, Malang Regency. Methods: This study employed a case study design using a Community Health Nursing Care approach to assess working groups residing in three neighborhoods (RT 20; RT 22, and RT 23) of RW 04. The instrument used was the Community Health Nursing Assessment Format, which measured demographic characteristics, family health conditions during the past six months, and health-related behaviors, including waste disposal, smoking habits, insurance ownership, and health service utilization. Results: Data were collected from 583 individuals representing 180 households, with 61.41% in the productive age group. Employment distribution showed that 138 individuals (23.67%) were private employees, 81 (13.89%) farmers, and 79 (13.55%) informal workers: laborers, domestic helpers, and construction workers. The most common diseases were acute respiratory infections (32%) and hypertension (26%). Two primary diagnoses were identified: Tendency toward Risky Health Behavior (D.0099) and Ineffective Health Maintenance (D.0003). The proposed interventions included Health Education (I.12383), Promotion of Healthy Behavior and Lifestyle (I.12472), education on the dangers of smoking and air pollution from waste burning, and screening for pulmonary tuberculosis (TB), chronic obstructive pulmonary disease (COPD), and cancer. Conclusions: Strengthening partnerships among Puskesmas, local government, and nearby industries is recommended to ensure the sustainability of occupational health initiatives.
