"These are the proceedings of the International Conference on ISMAC-CVB, held in Palladam, India, in May 2018. The book focuses on research to design new analysis paradigms and computational solutions for quantification of information provided by object recognition, scene understanding of computer vision and different algorithms like convolutional neural networks to allow computers to recognize and detect objects in images with unprecedented accuracy and to even understand the relationships between them.
The proceedings treat the convergence of ISMAC in Computational Vision and Bioengineering technology and includes ideas and techniques like 3D sensing, human visual perception, scene understanding, human motion detection and analysis, visualization and graphical data presentation and a very wide range of sensor modalities in terms of surveillance, wearable applications, home automation etc.
ISMAC-CVB is a forum for leading academic scientists, researchers and research scholars to exchange and share their experiences and research results about all aspects of computational vision and bioengineering."

ABSTRACT
This study investigated the production of bioethanol by anaerobic fermentation process using Zymomonas mobilis bacteria of raw materials cocopeat coconut fibers . Cocopeat coconut fibers which have been selected as a waste product and have economic value can be processed to produce bioethanol as a renewable alternative energy sources are environmentally friendly. The method used in this research are the delignification method, method of SSF Simultaneous Saccharification and Fermentation , and a simple distillation method. The parameters of ethanol fermentation, such as the, temperature variation of 32, 35 and 38oC, and period of fermentation with the variation of 72, 96, and 120 hours. Fungus Trichoderma viride produced a cellulase enzyme and processed cellulose into glucose, while Zymomonas mobilis process the glucose into ethanol product. Analysis of ethanol content was measured by using gas chromatography. The results showed that an initial pH of 5 reached a maximum condition at temperature of 35oC, fermentation period of 72 hours 3 days , and the ethanol content of 0.341. "

"Penghematan energi dan upaya mencari bahan bakar alternatif yang terbarukan seperti bioetanol perlu dilakukan saat ini. Produksi bioetanol dapat ditingkatkan diantaranya dengan mengoptimasi temperatur fermentasi dan waktu retensiya. Waktu retensi dipengaruhi oleh laju reaksi pembentukan, yang dalam penelitian ini akan diteliti lebih lanjut mengenai konstanta laju reaksi pembentukan bioetanol. Pada penelitian ini akan diproduksi bioetanol berbasis tandan kosong sawit TKS. TKS terlebih dahulu didelignifikasi untuk menghilangkan kandungan ligninnya, kemudian TKS tersebut dikonversi menjadi bioetanol dengan menggunakan metode Simultaneous Saccharification and Fermentation SSF. Pada proses ini, suhu reaksi divariasikan yaitu 30, 33, dan 35 agar diperoleh suhu terbaik, dengan pengambilan sampel setiap 24 jam selama 4 hari. Kondisi terbaik pada penelitian dicapai pada suhu 30 dengan waktu sakarifikasi dan fermentasi selama 24 jam. Koefisien kinetika yang diperolah pada kondisi terbaik tersebut yaitu maximum spesific growth reaction rate ?max = 0,008 h-1; monod constant Ks = 0,005 g/dm3; specific natural death constant Kd = 0,011 h-1; dan cell maintenance constant m = 0,457 h-1.

It is necessary for energy savings as well as searching for alternative renewable fuels, such as bioethanol. Bioethanol production could be improved such as by optimizing the fermentation temperature and retention time. The retention time is influenced by the rate of reaction formation, which in this study will be further examined on the reaction rate constant formation of bioethanol. In this research, bioethanol will be produced from oil palm empty fruit bunches EFB. Empty fruit bunches of oil palm EFB will undergo delignification process to remove its lignin content, then cellulosic rich oil palm empty fruit bunches EFB will then be converted into bioethanol using Simultaneous Saccharification and Fermentation SSF method. In this process, the reaction temperature variation 30, 33, and 35 performed to determine the optimum temperature, with sampling every 24 hours for 4 days. The optimum conditions in the study achieved at a temperature of 30 C in 24 hour of sacarification and fermentation. Meanwhile, the kinetic coefficients achieved in this optimum condition are maximum spesific growth reaction rate max 0,008 h 1 monod constant Ks 0,005 g dm3 specific natural death constant Kd 0,011 h 1 and cell maintenance constant m 0,457 h 1."
