Activities of teacher’s working memory in representing a picture are important in the teaching and learning process. This study aimed to reveal the tendency of teacher’s mental representation and teacher’s teaching styles in biology class using convention pictures. This research used descriptive method. The research was conducted by involving four high school biology volunteer teachers of grade XI from four schools in Lebak, Banten, Indonesia. Teacher’s teaching styles were measured by questionnaires and rubrics adapted from Grasha and teacher’s mental representations were measured using worksheets and rubrics developed based on the Causal Network Elicitation Technique (CNET) model. The data obtained were analyzed qualitatively. The results showed two dominant teacher teaching styles; there were expert style and facilitator style. The mental representation of teachers when reading convention picture was in the category of good (2 teachers), adequate (1 teacher) and inadequate (1 teacher). A teacher with expert teaching style tends to have a good mental representation compared to a teacher with facilitator teaching style.

The Qur'an is a guidence which explaines all about the universe to human being. The discovery of science has been able to explain the truth of the Qur'an scientifically. One of which is the principle of Heisenberg's uncertainty in the event of the universe destruction. The purpose of this research is to know: 1) Science's view of the event of the universe destruction (Big Crunch) in Qur’an [Al Infithaar]: 1-3, and How the relation of Heisenberg’s uncertainty principles and the law of thermodynamics II toward the collapse of the universe (Big Crunch) based on Scientific views and the Quran. This research is a qualitative research using library research method which analyzes the related books directly or indirectly. The results of the analysis stated that: 1) The concentration of mass, which is big enough, relates to some of the laws of physics, those are: Relativity, Heisenberg's uncertainty principles, and the law of Thermodynamic II; 2) The universe will return at its sole point, i.e; the absence of the universe; 3) The destruction of the universe is the destruction of the order of the universe which then the stars fall scatteredly because of the gravitational force that prevents them disappears, the balance of the universe diminishes, decreases and becomes uncertain, and eventually disappears.

Data on 2015 [9] show that less than 50 percent of provincial and local level bridges in Central Java are in good condition. In the other hand, it has been reported that local bridges in the city of Surakarta have been deteriorated and damaged. The maintenance and rehabilitation action often done based solely on incidental reports without systematic planning. Analytical Hierarchy Process, Fuzzy Analytical Hierarchy Process, and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) were used to compare the priority scale of bridge management in Kecamatan (District) Banjarsari, Surakarta. Bridge Management System 1993 (BMS 1993) standard was used to quantify bridge damage condition by means of direct visual observation. Scores used in this 3 different analysis were determined by comparing aforementioned 2 criteria and 9 sub criteria. Accordingly, criteria and subcriteria defined in this paper were based on the standard. The criteria employed were bridge damage condition and average daily traffic (ADT). Bridge condition criteria were then divided further into sub criteria; i.e. river stream, safety support building, foundation, pier, girder system, parapet, floor system, expansion joint, and other property. From 11 bridges considered in this study, Maris Bridge has the highest pirority determined in 3 different methods. AHP and TOPSIS methods show Ringin Semar Bridge the lowest priority to maintain. On the other hand, Fuzzy AHP determines Balapan Bridge as the lowest order. Keyword: Bridge Management, BMS 1993, AHP, FAHP, TOPSIS.
