Abstract

Based on data from the Central Statistics Agency (BPS), the use of chemical fertilisers in Indonesia has increased by 50% in the last two decades, contributing to the decline of soil fertility and groundwater pollution (Rosadi, 2023). Research by the Indonesian Institute of Sciences (LIPI) found that the use of biofertilisers from agricultural waste can reduce the need for chemical fertilisers by up to 40%, while improving soil fertility in a sustainable manner. This research will focus on the development of agricultural waste-based biofertiliser formulations, with trials of their application in various crop types and land conditions in Indonesia. This research uses an experimental method with a quantitative approach, which aims to develop and test the effectiveness of agricultural waste-based biofertilisers. Table 1. The Bima variety (a1) has a larger number of plants than the Mentes variety (a2). Nutrient management also has a major impact on plant growth. Application of one dose of recommended NPK together with 100 kg/ha of pearl NPK (b3) and one dose of recommended NPK together with organic fertiliser and biofertiliser (b4) resulted in the highest plant growth at 8 weeks of age (Table 1). In the experiment, intensive pest control was carried out in the field. As a result, onion caterpillar (Spodoptera exigua hubn) populations per clump were low and fusarium wilt (Fusarium oxysporum hanz) infestation levels were generally low in both variety and nutrient management treatments. There was no evidence that varietal treatments or nutrient management had a significant impact. The application of agricultural waste-based biofertilisers not only improves crop yields, but also supports the sustainability of the agricultural ecosystem by minimising the use of synthetic chemicals and optimising the use of available resources.

Abstract

This article discusses environmental management strategies in reducing the impact of company operations on ecosystems. Against the backdrop of increasing environmental damage due to carbon emissions, toxic waste, and ecosystem degradation, this article examines the concept and implementation of environmental management through a qualitative descriptive method. The study uses secondary data from scientific journals, books, and company reports to analyze the steps taken by companies in implementing environmentally friendly policies. The results show that the implementation of clean technology, energy efficiency, circular economy-based waste management, and collaboration with stakeholders significantly reduce environmental impacts. Case studies from PT Pertamina Geothermal Energy and PT Semen Indonesia Tbk show success in reducing carbon emissions by 150,000 tons and 2 million tons of CO2 per year, respectively. In addition, the use of alternative fuels and waste recycling are effective solutions to reduce dependence on fossil fuels. This article emphasizes the importance of green technology investment, public awareness raising, and cross-sector collaboration to support environmental sustainability. Thus, environmental management is not only a corporate obligation but also a strategic opportunity to improve operational efficiency and business reputation.
