Revisit the green barrier development for ammonia exposure preventive countermeasure at urea fertilizer Z Factory in South Sumatera, Indonesia

Abstract

Abstract The release of large-scale ammonia in the air by urea fertilizer plants Z has caused negative impacts on the environment, particularly to environmental pollution and human health. Some actions have been taken as a countermeasure, one of them is the development of Green Barrier, a living filter consist of various plantation that design based on its ability to absorb certain pollution substances in the ambient air. This article aims to analyze the development of the green barrier construction and its effectiveness as an effort to prevent the spread of ammonia gas around the urea fertilizer plant Z environment. Sequential explanatory with comparative analysis of data obtained from questionnaires using Spearman Coefficient Correlation, interviews, and data on green barrier construction processes used to achieve research objectives in this study. Based on the results of the study it was found that the existence of the green barrier was more effective in reducing noise than reducing the ammonia odour. This is also supported by field observations where the construction of a green barrier is still not fully optimal due to land acquisition problems, damage to several plants on the green barrier, and many green barrier areas that have not been planted by plants which are mainly bordered by community land.
