Abstract

The peat water studied contained colour, turbidity, organic substances, and iron that were sufficient to be analysed for the use of electrocoagulation. The aluminium electrodes were contacted with peat water by varying electrode plates, sedimentation time, electrolyte concentration, stirring speed, and contact time to produce clean water. The results showed that the electrocoagulator with the 3 pairs of electrode plates, 60-minute sedimentation time, 75 g NaCl electrolyte concentration, stirring speed at 75 rpm, and 60-minute electrocoagulation time was the most optimal variation. The results showed that the electrocoagulation method was able to reduce the pollutant levels in peat water. The results of this treatment also met the standards of the Ministry of Health and based on the calculation of cost incurred by the electrocoagulation method, i.e. $ 0.154/day, $ 4.641/month and $ 55.693/year.

Abstract

Background: Uterine rupture (UR) is a significant concern in obstetrics, particularly for women attempting a vaginal birth after cesarean section (VBAC). This systematic review focused to analyze the prevalence of uterine rupture in women who undergo VBAC based on literature from the past decade. Methods: The study followed PRISMA 2020 guidelines, reviewing English-language publications from 2014 to 2024. Editorials, duplicate reviews from the same journal, and papers lacking a DOI were excluded. The literature search was conducted using PubMed, SagePub, SpringerLink, and Google Scholar. Result: A total of 630 articles were initially identified through online databases (PubMed, SagePub, SpringerLink, and Google Scholar). After three rounds of screening, eight relevant studies were selected for full-text analysis. Conclusion: Uterine rupture in VBAC is rare but linked to risks like labor induction, short interdelivery intervals, and maternal health. Enhanced patient selection, monitoring, and access to antenatal care can improve safety and outcomes, especially in resource-limited settings.

Abstract

Introduction: Globally, Chronic Kidney Disease of Unknown etiology (CKDu) poses a growing medical and social challenge, particularly in agrarian countries with a high prevalence of pesticide exposure. Indonesia, is one of the countries with a dominant agricultural sector. Tanjungsari and Glonggong villages in Wanasari subdistrict, Brebes Regency, are agricultural areas with a high intensity of pesticide use. Methods: This research aimed to identify the prevalence of subclinical renal dysfunction and associated risk factors in horticultural farmers in areas with high pesticide exposure. This research applied a cross-sectional method involving 40 farmers aged 26-65 years from two villages in Wanasari District, Brebes Regency. Data collection was carried out through interviews, and examination of kidney function biomarkers (serum creatinine and eGFR). Statistical analysis was conducted using Logistic Regression tests. Results and Discussion: The study revealed that 37.5% of participants exhibited eGFR values <90 ml/min/1.73 m2, indicating subclinical impairment of kidney function. Employment duration >20 years (p=0.024; OR=6.000; 95% CI:1.263-28.498) and daily working hours >6 hours (p<0.001; OR=69.279; 95% CI:6.423-756.965) showed a significant association with reduced eGFR values. Occupational health interventions should prioritize managing the duration and intensity of exposure to hazardous substances in the workplace, regardless of the workers' gender. Conclusion: The conclusion is that the daily working hours and the employment duration of the farmers are significantly associated with impaired kidney function, potentially acting as an initial marker of CKDu.
