Meanwhile, efforts to find renewable energy sources as reserves require quite expensive costs with a relatively long duration. Therefore, it is necessary to research renewable energy sources, such as corn stovers and coconut shells. This study is generally carried out by making charcoal or carbonization, briquetting, and testing the quality of briquettes. The variables used in this study are the composition of corn cob charcoal and coconut shells. The composition of the mixture used consists of 5 comparative variables, namely sample A = 1: 1, sample B = 1: 2, sample C = 1: 3, sample D = 2: 1, and sample E = 3: 1 with a drying temperature of 100 oC. This study aims to produce biobriquettes from variations in the ratio of good and quality corn cob and coconut shell so that they can be used as environmentally friendly alternative fuels. This study concludes that the optimal mixture variation to produce good quality biobriquettes is found in sample C with a water content of 2.20%, ash content of 3.22%, sulfur content of 0.07%, and a calorific value of 7339 cal/gram because it has a lower optimization compared to other samples and meets the specified standards
Evaluation of Laboratory Waste Management at Mataram University as a Basis for Preparing Environmental Pollution Prevention Policies
Get PDFThis 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
