Abstract

This research discusses the application of the balance principle in laboratory waste management as a strategy to minimize environmental impacts. This principle aims to balance laboratory activities and environmental protection by reducing waste at the source, sorting it out, and using environmentally friendly waste processing technology. The research used a descriptive qualitative approach in the Mataram University laboratory. The research results show that applying the balance principle is still not optimal due to limited understanding, infrastructure and adequate policy support. Recommended strategies include implementing the 3R principle (Reduce, Reuse, Recycle), selecting safer chemicals, and increasing training and preparing clear SOPs. Waste identification reached (50%), with limitations in storage (44%) and transportation (43%). Management and final disposal were minimal (33% and 38%), increasing environmental risks. Documentation, reporting (43%), and regulatory compliance (43%) still need to be improved. The K3 aspect is quite good (54%), but emergency response procedures are still weak. Sustainable management (37%) and environmental monitoring (43%) lack effort in mitigating environmental impacts. Applying the principle of balance is important to achieve sustainable laboratory waste management.

Abstract

Hazardous and Toxic Waste (B3) from laboratories, especially those containing heavy metals (Hg and Cr) and several physical factors such as pH, TSS, and color, poses a serious threat to the environment if not managed properly. This study aims to estimate the adsorbent for the development of laboratory-scale wastewater treatment equipment based on the adsorption method using biochar, zeolite, and activated alumina. The research method involves preparing adsorbent materials, testing their effectiveness in reducing the content of heavy metal pollutants, and designing a waste treatment device. The combination of biochar, zeolite, and activated alumina was chosen due to their complementary abilities in removing heavy metal content from B3 waste in the Soil Chemistry laboratory. The treatment results showed significant reductions (p < 0.05) in heavy metal (Hg and Cr) levels in laboratory waste. The optimal combination is a formulation of biochar, zeolite, and activated alumina (1:1:1). Innovations in adsorbent technology for processing heavy metal waste in soil chemistry laboratories can be applied and further developed to create a clean and healthy environment.
