Abstract

Water quality is essential for community needs. This study uses physical, chemical, and biological parameters to evaluate the quality and sustainability of Anggoeya Spring, Kendari City. The Southeast Sulawesi Health Laboratory tests assessed compliance with water quality standards, while pollution levels were analyzed using the Pollution Index. Sustainability was examined through the RAP-SPRINGS method, focusing on ecological aspects. Results showed compliance with most standards, except for BOD, COD, and total coliform levels. Anggoeya Spring was classified as lightly polluted but ecologically sustainable. Key sensitive attributes land cover in the catchment area, land cover within a 200 m radius, catchment area criticality, and water source utilization-highlight the need for targeted conservation and rehabilitation efforts. Therefore, prioritizing land and forest management in the catchment area and surrounding zones is crucial for sustaining Anggoeya Spring. This includes the need for improved raw water treatment, especially water treatment technology, due to the high total coliform content in Anggoeya spring water. This study evaluates water quality, determines pollution levels, and analyzes sustainability using the RAP-SPRINGS method. It emphasizes crucial ecological factors for conservation, advocates land rehabilitation, and highlights the necessity of improved water treatment. Ultimately, it contributes to environmental preservation and sustainable water management.

Abstract

Atherosclerosis is a leading cause of coronary heart disease. This study analyses how elliptically shaped stenoses alter blood-flow velocity in coronary arteries. The governing equations are discretised with the finite-volume method, coupling pressure and velocity through the SIMPLE (Semi-Implicit Method for Pressure-Linked Equations) algorithm and accelerating convergence with the Successive Over-Relaxation (SOR) technique. A weighted Gauss–Seidel iteration whose over-relaxation factor ( in this work) damps low-frequency error modes, cutting the number of iterations needed for residuals to fall below 10⁻⁴ by roughly 40 % compared with the standard Gauss–Seidel scheme. Simulations of 30 %, 50 %, and 70 % constrictions were carried out in MATLAB R2013a and ANSYS Fluent. Quantitative and qualitative cross-validation of the two software packages confirmed consistent velocity and pressure fields, though minor discrepancies arose from differing numerical schemes and model assumptions, underscoring the need for experimental verification. The highest centre-line velocity occurred at 70 % stenosis—0.72075 m/s in MATLAB versus 0.90 m/s in Fluent—while the lowest was recorded at 30 %. Velocity–pressure profiles showed that increasing inlet velocity or degree of narrowing elevates velocity but decreases pressure, with the largest drop (11492.4 Pa in MATLAB; 11747.32 Pa in Fluent) again at 70% stenosis. Study limitations include modelling blood as a Newtonian fluid and idealising arterial geometry; future work should incorporate non-Newtonian rheology and patient-specific shapes to enhance physiological accuracy.

Abstract

In the current era of globalization, the role of government supervision in regulating the distribution of cosmetics must always be done by improving the quality of consumer protection. For this reason, the Indonesian Ulema Council (LPPOM MUI) has a strong task of researching, reviewing, analyzing and deciding whether food products and their derivatives, medicines and cosmetic products are safe for consumption. in terms of health and in terms of teaching Islam. For this reason, consumers must know what are the factors that influence consumer behavior towards cosmetic products that are not labeled halal? And what is the perception of the 2018 Islamic economic law students regarding cosmetic products that are not labeled halal?. The purpose of this study was to find out the perceptions of Islamic economic law students class 2018 about cosmetics that are not labeled halal in relation to consumer behavior. The nature of this research is field research. The type of research used in this research is descriptive and uses data collection techniques using interviews, documentation, and observation. In an interview with a 2018 Islamic Economic Law student, the data was processed using a qualitative analysis method using the inductive reasoning method. Based on the results of the study, the most dominant factor influencing consumer behavior in purchasing non-halal labeled cosmetic products by students of the Faculty of Sharia class 2018 INSURI Ponorogo includes several factors, namely close friends, self factors and environmental factors.
