Abstract
One important skill that can support the success of learning physics for students is problem solving skills. This study explores the level of problem solving skills of 54 first semester students (11 men and 43 women, age range 16-18 years) in the basic physics course in the science education study program, Bengkulu University. In the first lecture, students are given irregular straight motion concept, without being given examples of problems and how to solve them. In the second lecture, students are given essay tests that contain quantitative problems related to concepts that have been studied previously. Based on their answers, it was found that: none of the students sketched a picture to represent the problem; they wrote down what was known and asked of the problem; none of the students mentioned the physics principles that would be applied to solve the problem; none of the students explained what important things were to be controlled, the limits that had to be met, and the special principles of physics that can lead to the right equation; they write physics equations and do mathematical calculations; none of the students who write justifications of the results obtained as a representation of checking back on the results obtained; only 43 percent of students have correct calculation results on question number one, and 17 percent on question number two. Based on these results it was concluded that the students physics problem solving skills were still at a low level. These results can be used as consideration for the selection of learning methods that can develop students problem solving skills in subsequent lectures

Abstract
Many ingredients derived from animal have been distributed widely in foods, pharmaceutical, and cosmetic formulations which may invites issues due to religious restrictions. Thus, the species-specific detection has become an important issue among Muslims, Jews, Hindus, Vegan, and vegetarian communities. Some methods such as spectroscopy, chromatography, and DNA based method have been applied for this purpose. However, these methods use sophisticated technology, therefore need high skill and cost for industrial practice. Research needs to encourage the development of simple and portable instrument. This paper highlights the potency of the Maillard reaction for species-specific detection of animal derivatives in food, especially for gelatine. Gelatine from different sources revealed different amino acids composition. It will produce various sensory of active compounds such as colour, odour, and taste when subjected to Maillard reaction, depends on reactant substances and conditions of reaction. The differences will be the key principle in species-specific detection of the sources of gelatine.

Abstract
The objective of this study was to examine pre-service physics teacher understanding related to physics content knowledge by investigating the relationship between knowledge of the Basic Electrical Concepts (BECs) test and the student-s certainty in their physics knowledge. Data was collected from 57 preservice physics teachers with the BECs test and Certainty of Response Index (CRI) values. The BECs test with CRI was administered to pre-service physics students following accomplishment of a unit of study on electricity and simple circuit. The results of diagnostic test were classified into correct and incorrect answers, and CRI values were classified into certain and uncertain. High CRI value in incorrect answer on the BECs test implied that 26% preservice physics teachers had misconceptions about basic electrical concepts. Low CRI value in correct or incorrect answer on the BECs test indicated there were 53% preservice physics teachers providing the answer by guessing; due to no understanding or confusion about their understanding. There were 21% preservice physics teachers providing the answer correctly on the diagnostic test with high CRI value. It was concluded that the majority of preservice physics teachers (79%) were either guessing or had misconceptions about every item related to the electric basic concepts.

Abstract
Teaching materials are currently very dynamic in its development. The development of teaching materials is adjusted to the curriculum and student needs. Sometimes the basic things that are rarely considered in the development of teaching materials based on student needs, namely the text used as student reading material in making it easier for students to understand the subject. It finds it difficult for students in digesting the information or messages that they want to treat through the text, the technique is too long, errors in sentence structure, idea development, and the spelling used. This study aims to describe the thematic development patterns with language tools in the text of Mathematics and Natural Sciences teaching materials for Class VII Schools. This research method uses a descriptive analysis approach from the text contained in two teaching materials based on the 2013 Curriculum. This thematic progression model uses the Danes 1974 and Eggins 2004 models chosen as a theoretical analytical framework. The results of this study illustrates the pattern of progression themes and linguistic features in each field of teaching material analyzed. This will make it easier for students and teachers to understand the reading text contained in teaching materials. If the text of the teaching material has a thematic progression pattern and the language features are not good, this research can be an alternative evaluation in the development of teaching materials, especially in the selection of texts on teaching materials that will be developed by teachers or the government.
