“…Increased pH by exposure of POME also could affect the nutrient availability in the soil. Untreated POME also influences the capacity of soil to hold water and alters the composition of organic compounds (Nmaduka et al 2018). Phytotoxicity of POME caused by the high concentrations of polyphenol also interferes with plant and microorganism metabolism (Nwoko et al 2010, Anaerobic conditions and high temperatures caused by newly released POME may also reduce the population of microorganisms and alter enzyme activities, however, exposure to old POME may in fact increase the microorganism population as a result of elevated levels of organic compounds (Orji et al 2006, Ibe et al 2014.…”

Indonesia is renowned as an agricultural powerhouse, ranking first globally in oil palm production. This prominence in agriculture leads to the consistent generation of agro-industrial waste, notably Palm Oil Mill Effluent (POME). Effectively addressing these waste concerns is important due to their adverse impacts on aquatic ecosystems and the nation's health and economy. Anthropogenic wastewater with excessive phosphorus content can trigger eutrophication and toxic algal blooms, posing environmental risks and potentially precipitating a future clean water crisis. Thus, a comprehensive approach is necessary to restore the environment and biogeochemical cycles. Treatment efforts involving bioremediation agents aim to recycle organic and inorganic pollutants in the environment. Photosynthetic organisms like plants and microalgae serve as effective bioremediation agents, capable of absorbing excess phosphorus. They can utilize phosphate as an energy source to boost biomass. Integrating these bioremediation agents with bioengineering technology optimizes the treatment efficacy while simultaneously producing valuable biomass for products and bioenergy. This review article explores photosynthetic organisms' multifunctional role as phosphorus bioremediation agents for wastewater treatment, minimizing environmental pollutant impacts, and providing biomass for fertilizers, polymers, bioplastics, and renewable energy. Furthermore, this study unveils opportunities for future technological advancements in this field.

“…POME yang dihasilkan dari proses pengolahan CPO mengandung gas metana (CH4) yang apabila dibuang ke lingkungan dan terkumpul di atmosfer mampu memberikan dampak pemanasan global 25 kali lebih besar dibandingkan dengan Gas Karbondioksida (CO2) [7]. Selain itu, POME juga dapat menjadi ancaman bagi lingkungan jika langsung dibuang ke sumber air karena mengandung zat berbahaya dan bahan kimia yang berasal dari proses pengolahan sehingga dapat mencemari air dan udara [8] [9]. Dalam hal ini, perlunya upaya dalam memanfaatkan dan meminimalisir dampak yang ditimbulkan oleh POME menjadi produk yang berguna.…”

The substantial development of the palm oil industry in Indonesia is evident in the high production of Crude Palm Oil (CPO) as the primary product and Palm Oil Mill Effluent (POME) as a byproduct in palm oil mills. POME waste contains emissions that can harm the environment, necessitating proper waste management. This issue can be addressed by transforming the waste into biodiesel, as it still contains Free Fatty Acids (FFA) and triglycerides. The utilization of biodiesel can reduce the reliance on fossil fuels and environmental pollution. The research aims to evaluate the quality of biodiesel based on the SNI 7182:2015 standard, considering parameters such as Free Fatty Acid (FFA), acid value, density, water content, and viscosity through experimental processes involving sulfuric acid esterification and basic catalyst transesterification. The study is expected to provide information on the potential of biodiesel as a vehicle fuel and energy source for colt diesel engines, along with an emission analysis during the transition from biodiesel to solar. The biodiesel produced meets the standards for FFA (0.26%), acid value (0.57 mg/KOH), and density (0.871 g/ml). The waste volume of 490 m3/day generates 5,096 liters/day of biodiesel, sufficient for 23 units of colt diesel engines with 55% efficiency, producing an energy output of 988,902.91 J. The transition to biodiesel fuel can reduce CO2 emissions by 20.4%, NOx by 50%, and HC by 40%.Keywords – Biodiesel, POME, Renewable Energy, Esterification
