<b><i>A study of the production process of biodiesel from rubber seed oil using non-catalytic method that involving superheated methanol at atmospheric pressure bubble column reactor (BCR) has been reported. The quality of biodiesel generated from the process had not met the standard set by Indonesian Biodiesel Forum (FBI) in 2005. It was allegedly occuring since there was no degumming in the production process so that the sulfur and gum/phospholipid/latex contained by the crude rubber seed oils (CRSO) as results of the pressing process were can not be reducted although the transesterification process was held at a high temperature. The study aimed at producing FBI-2005 standarded biodiesel by involving degumming before the transesterification. There were 4 degumming materials used: (1) NaCl; (2) citric acid or C<sub>6</sub>H<sub>8</sub>O<sub>7</sub>; (3) sulfuric acid and NaOH; (4) zeolite and active carbon. The degumming sedimentation were done in two ways; natural and centrifuge (at 1165 rpm for 5 minutes) ways. The best degumming result was processed to be biodiesel under non-catalyst method using BCR superheated methanol under atmospheric pressure with the molar ratio (RM) of 160, at reaction temperature of 290<sup> o</sup>C. The biodiesel generated at such process was examined and found that it had met the standard of FBI 2005. The results showed that the degumming using citric acid 0.5% w/w and centrifuge sedimentation was the best method which could reduce gum/phospholipid from 17.1 mg/L to 5.8 mg/L (66% down). The quality of rubber seed biodiesel under degumming process using citrid acid has meet the standard of FBI 2005 than be ready to be marketed.</i></b>

Currently, the growth of information and technology is rapid. It makes a lot of things in various fields including education becoming more effective and efficient. In education, one of its implementation which is a game is proven to be a useful tool to support conventional teaching methods and bring a more natural understanding of learning materials. Moreover, as a product of the popular culture in modern society, video game mirrors the general culture practice in real life and reflects it via its own culture inside the game. This makes a video game can give a contribution to the social construction of reality as it affects the player’s view towards learning in real life and vice versa. From there, we see that there is an opportunity for learning about religion to be supported by its utilization to provide an interactive and fun learning experience. In this paper, we discuss how a video game is implemented to support religious learning. The game was developed with the scrum method where we surveyed to gather the user requirements before the design step. The game design was made by using the use case diagram and storyboard, and it was built using Unity version 2017.3.0f3.

Technology has improved a lot comparing to the previous years. The improvement can be seen from various development of a program that may benefit human life. One example of the advancement of technology is artificial intelligence (AI). AI has taken a considerable part in becoming the primary necessity in computer programming. One famous example of AI is object recognition. An arrangement of codes is established for the machine to recognize a picture that is inputted. Even so, the use of object recognition programs that may help mental disorder children is still low –- considering that they are still in the age where education is crucial. However, the standard approach of teaching them is not the right way to make them understand since they need individual adjustments and appropriate training for them to follow. Therefore. We are proposing an application that will help to educate mental disorder children through the use of object recognition in visual learning. The app will have built-in features such as vocalize the object’s name, which will help mental disorder children to know and remember how it is pronounced. Other features to further improve the education has guessed the word and draw the object which will help them to understand how the object is shaped. Moreover, Researches have proved that learning visually will help mental disorder children to understand better.
