Publication Children as Victims in the Social Media: The Islamic Perspective(American Scientific Publishers, 2018) ;Shah, HA ;Yusof, N ;Norfadhilah Mohamad Ali ;Abd Shukor, S ;Abidah Abdul Ghafar ;Ahmad, NMMusa, NAThe emergence of various new media that are viewed as becoming greater, more influential and capable of shaping the thoughts of the society is the greatest challenge in today's world. As a platform that functions as a double-edged sword, the social media crime involving children has become ubiquitous. The involvement of syndicate and groups among adults behind this crime, the irresponsible parents and families as well as the lack of religious or spiritual knowledge are believed to be the main factors behind the increasing trend of this crime. In Malaysia, research has shown that one out of every ten children under eighteen years old is the victim of the social media crime. The paper aims to analyse the development of social media and its impact on children with special reference to the Islamic principles. Methodology adopted are library-based study involving analysis of literature on evolvement of social media and its risk on children, and doctrinal analysis of the Islamic principles relevant to this. The paper examines the social media issues relating to children. Then, its identifies some of the Islamic principles that may provide alternative solution to the issue of children as victims in the social media. It is also suggested that, severe punishment to the individuals or groups that manipulate the children needs to be enforced and the commitment of parents, families and communities in eradicating the crimes also needs to be empowered. - Some of the metrics are blocked by yourconsent settings
Publication Optimization of process condition for extraction of gelatin from red tilapia skin (Oreochromis niloticus) by High Pressure Processing (HPP)(Univ Putra Malaysia Press, 2017) ;Yusof, N ;Jaswir, I ;Jamal, P ;Jami, MSOctavianti, FExtraction of gelatin using traditional acid-base pretreatment method has several limitations such as time consuming and causes serious water pollution. Chemical treatment often being used as an alternative process to overcome the weaknesses of the conventional method. However, excessive chemical elements would damage the structure of the gelatin due to its high sensitivity to the acid content. High Pressure Processing (HPP) is a novel and environmental friendly method that has been suggested to assist gelatin extraction. Pressurization during pretreatment could reduce the extraction time and amount of acid used. It also has a potential in enhancing the properties of the gelatin extract and increasing the gelatin yield. In this research, One-Factor-at-Time (OFAT) and optimization study were done to determine the optimum parameters for extraction of gelatin assisted by HPP from red tilapia skin. Four parameters; applied pressure, pressure holding time, ratio of acid to skin and extraction time have been selected for the OFAT design and concentration of the gelatin extract and percentage of yield gelatin were evaluated. From OFAT, optimum technical parameters for response surface optimization design were 250 MPa pressure, 7.5 ml of acid to 1 g of skin and 12 hours extraction time. Pressure holding time was fixed for 10 min. FCCCD has been used for optimization study. Results from the data shows that the optimum conditions for gelatin extraction from red tilapia skin were 250 MPa for pressure, 10 min of pressure holding time, 7.5 ml of acid for 1 g of skin and 12 hours of extraction time while the maximum concentration and yield were 19.51 mg/ml and 32.04% (320.4 mg/g), respectively. These findings proved that HPP could increase the concentration and the yield of the gelatin while reducing the chemical waste and shortening the extraction process. (C) All Rights Reserved
