The research was conducted to the students of Al-Kausar Internat Junior high school as an example of school which has applied the concept of information literacy in one subject and Arrahman Junior high school as an example of school which has not applied the concept of information literacy yet. The aim of this research was to find out whether there is a significant differences between students' literacy ability in finishing task exercises from those school. The method used in this research was a descriptive comparative method to find out the differences between both of objects in this research. The data were collected through questionnaire, interviews, and library study. The respondents are 53 students selected through Proportionate stratified random sampling techniques. The findings show there is no significant differences between students of Alkautsar junior high school and Ar Rahman junior high school on their students' information literacy ability. However, from the output scores of mean view, Al Kautsar Junior high school has a larger score than Ar Rahman junior high school. Therefore, Alkautsar Junior high school students have a better information literacy ability compared to Ar Rahman Junior high school students.

This study aimed to investigate; the types of backchannels and why the research participants in this study used backchannels in their classroom interaction. A case study involving a female lecturer and a female selected student met the criteria. The data were gathered from the research participants in the form of observation and interviews. This study revealed that (1) the types of backchannels used by the participants in the classroom interactions were backchannels vocal and backchannels silent. The backchannels vocal consisted of words form, phrases form, sentences form, and sounds identification; meanwhile, the backchannel silent concerned on head nods, the facial expression of the smile, gestural signal, and eyes movement; (2) the reasons why the participants uttered and produced both backchannel vocal and backchannel silent were to show the continuers signal, the statements signal, the social conditions, and the emotional signal.

Gambir is a type of plantation plant that has many benefits. Gambir extract can be used for the food, cosmetic, pharmaceutical, and leather tanning industries. However, the availability of gambier has decreased in production. Hence, information and technology for propagating Gambir seeds in vitro is needed. The growth of plant explants can be impacted by the application of growth regulators and explant sources in-vitro. This study’s purpose was to ascertain the connection between BAP concentration and explant sources concerning the development of gambier shoots. In addition, it is also to obtain of BAP and the best source of explants for the induction of the gambier shoots. In this study, a Factorial Completely Randomized Design (CRD) with 6 treatments that were each repeated five times was used. There are two levels of explant source and three levels of BAP concentration, the first of which is the concentration of BAP (2 mg/l, 4 mg/l, and 6 mg/l) (the first node and the third node from the shoot). The findings demonstrated that, in general, 100% of shoots could form when BAP and explant sources were concentrated. The concentration of BAP and the origin of the explants significantly influenced the emergence time of the shoots, with the quickest time of budding occurring after 3.8 days at a concentration of 2 mg/l BAP at the third node. 6 mg/l BAP was the optimal treatment for increasing the number of gambier leaves and shoots.
