Research ArticleOpen accessEvery word in the titlePalm Oil Sludge Fermentation with Pleurotus ostreatus and its Application in Laying Quails' RationAde Trisna, Nuraini, Yoze Rizal, MirzahPalm oil sludge is a byproduct of palm oil processing which is still limited in its use as a constituent of poultry feed. This study aims to improve the quality of palm sludge fermented with Pleurotus ostreatus and to determine its effect on the production of laying quail. The study was divided into 2 stages of research. Phase 1 of … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 4 · 9 Dec 2020 · 7,630 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleThe Effect of Higher Sludge Recycling Rate on Anaerobic Treatment of Palm Oil Mill Effluent in a Semi-Commercial Closed Digester for Renewable EnergyAlawi Sulaiman, Zainuri Busu, Meisam Tabatabaei et al.Problem statement: A 500 m3 semi-commercial closed anaerobic digester was constructed for Palm Oil Mill Effluent (POME) treatment and methane gas capture for renewable energy. During the start-up operation period, the Volatile Fatty Acids (VFA) accumulation could not be controlled and caused instability on the system. Approach: A settling tank was installed and sludge was recycled as to provide a … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 9,210 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleReduction of Ammonia Volatilization through Mixing Urea with Humic and Fulvic Acids isolated from Palm Oil Mill Effluent SludgeShamsuddin Rosliza, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Ammonia volatilization from surface-applied urea may be substantial but it is possible to control it by mixing urea with acidic substances such as Humic Acids (HA) and Fulvic Acids (FA). The objective of this study was to compare the effects of urea-HA, urea-FA, urea-acidified (HA+FA) mixtures on ammonia loss, soil pH, soil exchangeable ammonium and available nitrate accumulation … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,350 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Microwave and Ultrasonic Pretreatments on Biogas Production from Anaerobic Digestion of Palm Oil Mill EffleuntN. Saifuddin, S A. FazliliProblem Statement: Oil palm production is a major agricultural industry in Malaysia. In 2006, palm oil mills in Malaysia produced more than 58 million tonnes of Palm Oil Mill Effluent (POME). Existing treatment in a series of open lagoons at high ambient temperatures, results in the uncontrolled production of methane and carbon dioxide, which are both green house gases (GHGs). … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,986 accessesView PDF Cite
