<![CDATA[Hypertension is a global health problem with high prevalence and is a major risk factor for cardiovascular disease. One of the main mechanisms of hypertension is increased Angiotensin Converting Enzyme (ACE) activity. The use of synthetic ACE inhibitors often causes side effects, such as nausea, hyperkalaemia, headaches, swelling of the lower skin, coughing, taste disturbances, and angioneurotic edema. Therefore, natural-based alternatives are needed. Lime leaves (Citrus amblycarpa) are known to contain various bioactive compounds that have the potential to act as ACE inhibitors. This study aims to analyze the interaction of active compounds in lime leaves with ACE through molecular docking, as well as to predict their ADME profile and toxicity. The study was conducted in silico using PyRx–AutoDock Vina for molecular docking, PyMOL and BIOVIA Discovery Studio for interaction visualization, SwissADME for ADME prediction, and ToxTree for toxicity analysis. Method validation was performed based on an RMSD value < 2Å. The results of the study indicate that 1,3-benzenedicarboxamide is the best compound with an RMSD value of 1.998 Å and a bond free energy (ΔG) of −6.4 kcal/mol, forming specific amino acid residue bonds similar to the native captopril ligand. ADME predictions meet Lipinski's Rule of Five criteria and fall into the low toxicity category (Class I) based on Cramer's rules. The compound 1,3-benzenedicarboxamide has the potential to be developed as a candidate ACE inhibitor for hypertension therapy.]]>

<![CDATA[The COVID-19 pandemic has had a major impact on the global healthcare system, including the postponement of elective operations due to limited resources and efforts to prevent the transmission of the virus. Globally, more than 28 million operations were postponed, including in Indonesia. Delays have an effect on patient safety because they risk having a serious impact on patients. This study aims to understand the impact of delaying elective surgeries on patient safety during the COVID-19 pandemic. The design of this research is a literature review. Searching for articles through the Pubmed, Science Direct, and Google Scholar databases (2020-2025) using the keywords "patient safety" AND "elective surgery" OR "delay elective surgery" AND "covid elective surgery" OR "delay covid elective surgery". Data are extracted based on objectives, research design, research samples, research locations, and findings. The total number of article findings was 844, but only 8 articles met the inclusion criteria. The impact of delay on patient safety is classified into three main categories: (1) Physical health includes decreased physical health score, increased pain, increased risk of falling, and increased weight gain (average 4 kg); (2) Mental health includes anxiety, depression, frustration, and adverse psychological effects; (3) Delay in the recovery process. The delay in elective surgeries during COVID-19 has an impact on patient safety, namely physical health, mental health, and delays in the patient's recovery process.]]>

<![CDATA[Effectiveness of Skincare Therapy and Topical Treatment in the Management of Perioral Dermatitis at Geps Aesthetic Clinic.Perioral dermatitis (PDO) is an inflammatory skin disease characterized by erythema, papules, and pustules around the mouth. Skincare and topical treatments are often used to reduce inflammation and improve the skin barrier, but the effectiveness of their combination in reducing the severity of DPO is rarely evaluated. This study aims to analyze the effectiveness of skincare and topical treatments in the management of DPO at Geps Aesthetic Clinic. The study used an observational analytical design with a quantitative approach based on medical records. The sample consisted of 68 patients from January 2024–April 2025 using a total sampling technique. Severity was assessed using the Perioral Dermatitis Severity Index (PODSI) from month 0 to month 3 and analyzed using the Mann–Whitney test. The results showed a significant decrease in PODSI scores in the first (p<0.001), second (p=0.043), and third (p<0.001) months. In the third month, 72.1% of patients were in the mild category and 2.9% were in the severe category. The combination therapy was effective in gradually reducing the severity of DPO over three months.]]>

<![CDATA[This research aims to comprehensively analyze the 2005 BP Texas City accident by integrating Fault Tree Analysis (FTA), Layers of Protection Analysis (LOPA), and Aspen HYSYS conceptual simulation. Using a qualitative descriptive approach, this study reconstructs systemic failures based on official investigation reports. FTA results reveal complex interactions between instrumentation failures, operational deviations, and design weaknesses as primary causes, while LOPA evaluation demonstrates the ineffectiveness of all independent protection layers in preventing hazard escalation. Furthermore, Aspen HYSYS simulation visualizes the dynamics of mass and energy imbalance during the start-up phase leading to column overfilling. This research contributes significantly to the development of process safety education by providing an integrated risk analysis framework to understand the evolution of industrial accidents holistically. The practical implications emphasize the urgency of implementing inherently safer designs, improving start-up management, and strengthening safety culture to prevent the recurrence of catastrophic incidents in the future.]]>

<![CDATA[This study evaluates occupational health risks due to exposure to physical factors in the workshop of PT Wesi Kuning Sukses using a quantitative observational design with a cross- sectional approach. The methodology integrates Similar Exposure Groups (SEG), semi- quantitative Health Risk Assessment (HRA), and ArcGIS® spatial modeling. The measurement procedures are based on national technical standard literature studies, including SNI 8427:2017 (noise), SNI 16-7061-2004 (heat), SNI 7062:2019 (lighting), SNI 7054:2019 (vibration), and SNI 16-7060-2004 (UV radiation). The results show noise (93 dBA) and ultraviolet radiation (0.71 µW/cm²) as high-risk priority threats because they exceed the Threshold Limit Value (TLV). Conversely, the parameters of lighting, heat, and vibration are categorized as medium risk according to Permenaker No. 5 of 2018. Spatial analysis identified critical hazard zones within a radius of 0–9 meters, while areas beyond 15 meters were deemed safe for residential use. Although biological monitoring did not reveal acute complaints, latent risks remain. The integration of SEG, HRA, and ArcGIS® proved effective in developing an accurate industrial hygiene management system for long-term occupational health protection.]]>
