Abstract

Public health reflects a complex and dynamic interaction between various determinants, where environmental conditions play a crucial role in influencing disease distribution patterns. The type of research used is qualitative through a descriptive approach. Data from this study were collected through medical records of patients visiting the Lubuk Alung Health Center during the period January to December 2024. The data collection process was carried out by health center officers by accessing medical records to document the type of disease and the number of cases based on their respective work areas. Furthermore, each case of disease was classified according to the type of disease and the patient's area of ​​residence. This study was conducted in the work area of ​​the Lubuk Alung Health Center, Padang Pariaman Regency, West Sumatra. The results of this study found that the distribution of the ten most common diseases was greatly influenced by local environmental conditions in seven villages, namely Air Tajun, Balah Hilir, Lubuk Alung, Pasir Lawas, Pangkalan Kasiak, Sei Abang, and Singguling. The disease with the highest number of cases was ARI (393 cases), followed by Diabetes Mellitus (355 cases), Hypertension (196 cases), Schizophrenia (168 cases), Dyspepsia (135 cases), Cephalgia (35 cases), Febris (56 cases), Skin Disease (45 cases), Heart Disease/HT (50 cases), and Other Diseases (51 cases). Balah Hilir and Pangkalan Kasiak villages showed the highest prevalence of diseases in general, with Balah Hilir recording the highest cases of ARI (97), Diabetes Mellitus (63), Dyspepsia (30), and Heart Disease/HT (11), while Pangkalan Kasiak dominated cases of Diabetes Mellitus (79), ARI (85), and Hypertension (65). Sei Abang also had high figures for ARI (67), Schizophrenia (17), and Skin Disease (12). In contrast, villages such as Pasir Lawas and Lubuk Alung had relatively lower cases of most diseases. This uneven distribution of disease indicates the strong influence of local environmental factors such as air quality, sanitation, lifestyle, and health infrastructure, so that specific area-based interventions are needed to improve overall public health.

Abstract

This study aims to assess the carrying capacity of the Anai River Basin (Watershed) in West Sumatra Province in response to increasing anthropogenic pressures and environmental changes. The research employed a spatial analysis approach utilizing remote sensing data and geographic information systems (GIS) to evaluate land cover conditions, water quality, and erosion levels. Carrying capacity analysis was conducted by calculating an environmental carrying capacity index, which included hydrological aspects, water quality, and the ecosystem's capacity to provide environmental services. The results indicate that the Anai River Basin is experiencing significant ecological pressure from land use changes, particularly the conversion of forests into agricultural land and settlements. Erosion rates in several sub-watersheds reached moderate to severe categories, with an average value of 15-25 tons/ha/year. River water quality demonstrated a decline in several parameters, especially increased turbidity levels and sediment content during the rainy season. The hydrological carrying capacity of the Anai watershed remains in a moderate category (index 0.65) but has shown a declining trend over the last five years. The findings indicate the necessity for implementing sustainable watershed management strategies. Management recommendations include forest conservation in upstream areas, the application of soil and water conservation techniques on agricultural land, the development of a regular water quality monitoring system, area zoning based on vulnerability levels, rehabilitation of 2,500 hectares of critical land, and the strengthening of watershed management institutions involving the active participation of local communities.

Abstract

The purpose of this research is to analyse the potential of water catchment areas and the impact of land cover change from 2010 to 2024. The research method used is quantitative research, with a descriptive approach. The analysis technique in this study uses the maximum likelihood analysis method, in analysing the classification of land cover in 2010 and 2024, and overlay analysis in analysing the potential of natural water catchment areas, land cover changes in 2010-2024, and the index of potential water catchment areas. Based on the results of the study, it can be concluded that the Batang Arau watershed has experienced a decrease in the area of potential water catchment areas, covering an area of 1057.80 hectares with a percentage of 5.94%, although it has increased the potential of water catchment areas covering an area of 238 hectares with a percentage of 1.34%, but the increase is not proportional to the decrease that has occurred. This decrease is due to land cover change from 2010-2024, with a reduction in forest area of 5.93%, wetland agriculture 2.49%, water bodies 0.02%, and grass 0.53%. This was accompanied by an increase in built-up areas of 7.94%, mixed gardens 0.73%, fields 0.10%, natural open land 0.002%, and shrubs 0.11%, So it can be concluded that the decrease in water catchment area is due to the reduction of forest area (natural vegetation), accompanied by an increase in built-up area

Abstract

The Batang Arau River in Padang City exhibits contrasting environmental conditions between its upstream and downstream segments. The upstream–midstream areas still maintain good water quality with positive carrying capacity, while the downstream segment has exceeded its natural assimilation limit due to increasing pollutant loads originating from domestic and community activities. This study aims to analyze water quality, calculate carrying capacity, and model the relationship between community behavior and the river’s assimilation capacity using a system dynamics approach. The modeling results indicate a continuous decline in carrying capacity driven by population growth and waste generation, illustrating that human behavior has a direct impact on the ecological balance of the river. Therefore, sustaining the ecological function of the Batang Arau River requires integrated pollution control policies, community-based waste management, and continuous environmental education to enhance public awareness and ensure the long-term sustainability of the river ecosystem.
