Abstract

Sago is a carbohydrate-producing plant that is widely found in Papua. The main product of sago plant processing is sago starch which in the extraction process is carried out with the help of water media. Water that has been used in the extraction process of sago starch is generally only disposed of as waste that is not useful, even potentially polluting the environment. Therefore, to improve the quality of liquid waste, filtration needs to be carried out. This study aims to see the effect of several types of filtration media on the quality of sago extraction wastewater. In this study three types of filtration media were used, namely sand (P), coconut fiber (S) and coconut shell charcoal (A) and a combination of sand and coconut fiber (PS), sand and coconut shell charcoal (PA), coconut fibers and charcoal coconut shell (SA). The parameters of the quality of the sago extraction wastewater were observed in total suspended solids (TSS), total dissolved solids (TDS), pH, temperature, odor, and color. The results showed that coconut shell charcoal filtration media was better than the other two types in decreasing TSS and TDS by 17% and 24% respectively. However, if the filtration media was combined, it will produce a better quality of wastewater compared to a single filtration medium (without combination) for all observation parameters. An increase in pH and odorless happened for the wastewater after filtration in all treatments

Abstract

Penemuan sumber bahan bakar terbarukan sangat penting untuk menjawab permasalahan keterbatasan energi bahan bakar berbasis fosil dalam memenuhi kebutuhan energi yang terus meningkat. Selain itu, penggunaan bahan bakar terbarukan diharapkan dapat mengurangi pencemaran lingkungan yang selama ini bersumber dari emisi gas CO2 hasil pembakaran bahan bakar fosil. Salah satu sumber bahan bakar alternatif terbarukan masa depan adalah mikroalga. Pengembangan mikroalga sebagai sumber energi terbarukan terus dilakukan karena memiliki keuntungan dibandingkan sumber energi lainnya, seperti laju produksi biomassa yang tinggi, tidak berkompetisi dengan bahan pangan, serta tidak membutuhkan lahan yang luas untuk pertumbuhannya. Technical review ini diarahkan untuk memberikan informasi tentang pengembangan dan pemanfaatan mikroalga sebagai sumber energi akternatif terbarukan, termasuk teknologi panen dan korvesi mikroalga menjadi bahan bakar.MICROALGAE: FUTURE RENEWABLE ENERGY SOURCES ABSTRACTThe discovery of renewable fuel sources is critical to address the problem of limited fossil fuel energy in meeting the increasing energy demand. In addition, the use of renewable fuels is expected to reduce environmental pollution that has been sourced from CO2 emissions of fossil fuel combustion. One of the future renewable alternative fuel sources is the microalgae. Development of microalgae as a renewable energy source continues to be done because it has advantages over other energy sources, such as high biomass production rates, not competing with foodstuffs, and does not require extensive land for growth. This Thechnilcal review is directed to provide information on the development and utilization of microalgae as a renewable alternative energy source, including harvesting technologies and microalgae convertion into fuel.Keywords: microalgae, biodiesel, cultivation, energy
