Research ArticleOpen accessIn the author namesMicrowave-Assisted Co-Pyrolysis of Bamboo Biomass with Plastic Waste for Hydrogen-Rich Syngas ProductionN. Saifuddin, P. Priatharsini, S.B. HakimConcerns about diminishing fossil fuels and increasing greenhouse gas emissions are driving many countries to develop renewable energy sources. The knowledge of the dielectric property is essential to design and develop microwave technology for processing biomass materials. Bamboo biomass was subjected to microwave pyrolysis, to determine the influence of each process on the yield and composition of the derived gas, … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 16 May 2016 · 9,121 accessesView PDF Cite

Research ArticleOpen accessIn the author namesMicrowave Assisted Bioethanol Production from Sago Starch by Co-Culturing of Ragi Tapai and Saccharomyces CerevisiaeN. Saifuddin, Refal HussainProblem statement: Environmental issues such as global warming and recent events throughout the world, including the shortage of petroleum crude oil, the sharp increase in the cost of oil and the political instability of some crude oil producing countries, have demonstrated the vulnerability of the present sources for liquid fuel. These situations have created great demand for ethanol from fermentation … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 18 Jul 2011 · 7,898 accessesView PDF Cite

Research ArticleOpen accessIn the author namesHeat-Modeling of Microwave Assisted Epoxidation of Palm Acid OilN. Saifuddin, L. Wei Zhan, K. Xin NingProblem statement: While microwave chemistry could well be the most convenient, rapid and energy-saving way to initiate a chemical reaction, the issues of thermal versus microwave specific effect remain unaddressed. Approach: A three-dimensional Finite Element Model (FEM) was developed to predict temperature profile during the enzymatic epoxidation of palm acid oil using microwave heating. Three-dimensional partial differential equations are formulated … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,676 accessesView PDF Cite

Research ArticleOpen accessIn the author namesThe Effect of Electrical Properties by Texturing Surface on GaAs Solar Cell EfficiencyH. Abdullah, A. Lennie, M. J. Saifuddin, I. AhmadProblem statement: This project discusses on the method to resolve the optical losses problem that have been hindering the totality efficiency of the photovoltaic. Solar cell simulation could be useful for time saving and cost consumption. The Silvaco software is not widely used in designing the 2D solar cell devices because there is lots of 1D, 2D and 3D-simulation beside … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,785 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEffect 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

Research ArticleOpen accessIn the author namesEffect of Stages of Maturity and Ripening Conditions on the Biochemical Characteristics of TomatoK.M. Moneruzzaman, A.B.M.S. Hossain, W. Sani, M. SaifuddinAn experiment was carried out to evaluate the biochemical characteristics of tomato in different maturity stages and ripening conditions. Tomato (Lycopersicon esculentum Mill) fruits (cv. Ruma VF) were harvested at the three maturity stages viz., mature green, half ripen and full ripen and stored at three condition control (without covering), straw covering and CaC2 + straw covering. At that time … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 8,046 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEffect of Stages of Maturity and Ripening Conditions on the Physical Characteristics of TomatoK.M. Moneruzzaman, A.B.M.S. Hossain, W. Sani, M. SaifuddinThe study was carried out to undertake the effect of different stages of maturity and ripening conditions on the physical characteristics of tomato fruit during the process of ripening. Fruit of three maturity stages viz., mature green, half ripen and full ripen were kept under three ripening conditions viz., floor without covering(control), covering with straw and CaC2+ straw covering.
