Abstract

KPSP Setia Kawan has two types of farms, namely conventional dairy farms and organic dairy farms. The research results show that in the milk production process of 1 kg of ECM (Energy Corrected Milk) which was delivered to the farm gate for 1 year, the total carbon footprint of milk produced by dairy farms in 2010 was 1.23 ± 0.04 kg CO2 Eq/kg ECM, 80% comes from on-farm activities. This research will apply the Life Cycle Assessment method with the CMLIA Baseline impact method. This method can be used to carry out impact assessments in the livestock sector so it is common for LCA studies in the dairy sector so it is most suitable for conducting comparative studies. It is hoped that with this research, animal husbandry can find out the effectiveness of implementing organic cattle farming in reducing environmental impacts compared to conventional cattle farming and help promote animal husbandry that prioritizes environmental aspects in the production and supporting processes.

Abstract

The coriander cracker industries in Nganjuk City, commonly structured in Small Business scales are  still implying conventional equipment in its production. High daily production volumes are resulting the large amounts of liquid waste containing pollutants exceeding Indonesia’s Threshold Value specifically in Chemical Oxygen Demand (COD) at 131.2 mg/L and Total Suspended Solids (TSS) at 203 mg/L. This condition causes serious environmental risks toward improper treatment. The biofilter system is one of wastewater treatment method with a simple and applicable way, applying a biological treatment approach utilizing microorganisms to reduce organic contaminants. This study aims to analyze the influence of media type on the removal efficiency of COD and TSS concentrations in coriander cracker industries’ wastewater using an aerobic biofilter system with the bioball and Kaldness K1 media. Performance testing of the aerobic biofilter demonstrated that the reactor with Kaldness K1 media achieved the highest removal efficiencies, eliminating 85.96% of COD and 95.01% of TSS by day 12. The study confirms that the Kaldnes K1 media's porous surface structure and high specific surface area enhance biofilm growth of microorganisms, thereby optimizing organic matter degradation processes.
