Abstract

Introduction: Daily activities at Port X generate domestic wastewater containing total coliform and Total Suspended Solids (TSS) levels exceeding the environmental quality standards. Elevated concentrations of these parameters pose a risk of waterbody pollution and can lead to gastrointestinal diseases in nearby communities. Objective: This study aims to evaluate the effect of calcium hypochlorite (kaporit) treatment on the reduction of total coliform and TSS in domestic wastewater at Port X, Batam City, in 2024. Method: A true experimental research method was employed, using a pretest-posttest control group design. Samples were treated with varying doses of calcium hypochlorite, followed by laboratory analysis to measure changes in coliform and TSS concentrations. Primary data were analyzed using paired t-tests with a significance level of p < 0.05. Result and Discussion: The results indicate that calcium hypochlorite treatment significantly reduces both total coliform counts and TSS levels. The most effective treatment was achieved with a dosage of 2 g/L of calcium hypochlorite combined with 4 hours of aeration, resulting in reduction efficiencies of 82.71% for total coliform and 85.16% for TSS. Conclusion: It can be concluded that calcium hypochlorite is effective in reducing pollutant loads in domestic wastewater, demonstrating its potential as an efficient and affordable solution for wastewater treatment in port areas.

Abstract

In the era of globalization, industrial and business activities significantly contribute to environmental impacts, making systematic environmental management crucial. This study analyzes the implementation of an Environmental Management System (EMS) at PT “X” based on ISO 14001:2015, evaluates its performance, and identifies its impact on environmental sustainability. A qualitative approach was employed, with data collected through in-depth interviews, field observations, and document analysis. Informants consisted of five representatives from key functional areas, including top management, accounting, HSES (Health, Safety, Environment & Security), and Quality Assurance as the internal auditor. The interview guidelines were designed according to ISO 14001:2015 clauses to ensure comprehensive coverage. The findings indicate strong top management commitment in supporting EMS implementation through policies that encompass planning, execution, and monitoring. The organizational structure effectively facilitates the environmental management cycle, including identifying, addressing, and resolving findings categorized as major non-conformities, minor non-conformities, and opportunities for improvement. These serve as the basis for performance evaluation and continuous improvement. In conclusion, PT “X” has effectively implemented EMS in line with ISO 14001:2015 and complies with Indonesia’s Law No. 32/2009 on Environmental Protection and Management. The company demonstrates environmental responsibility, and continuous improvement is recommended to strengthen sustainability and stakeholder trust.
