The purpose of this study is to improve the Habits of mind of students through the problem-based learning (PBL) model based on the otetic assessment of mathematics learning. The study was conducted on 39 students of class X. The research method used was an pre-experiment method. with One group pretest-posttest design. Data analysis carried out was Normality Test, Homogeneity Test, t Test, and N gain Test. The results of this study indicate that the application of authentic assessment-oriented PBL method can improve students' habit of mind in mathematics learning. This can be seen from the increasing results of assessment of creative thinking, and student self-regulated. the results of the creative thinking assessment are N-Gain values of 0.47 or included in the medium criteria and the results of the hypothesis test state that the significance is smaller than the reference sig it can be said that there are significant differences between the pretest and posttest values. The results of the assessment of self regulation, show the value of N gain 0.59 in the medium category so that it is said there is an increase between the value of the pretet results and the value of the posttest results.

The purposes of this study to determine whether the web-oriented constructivism instruction approach can improve student's habits of mind. The method used in the study is pre-experiment method with one-group pretest-posttest design who applied to students in 10st grade of senior high school and total 38 students. Research data is collected using critical thinking test, creative thinking test, self-regulation questionnaires, and contributes a web-oriented constructivism instruction approach to habits of mind observation sheet. Data were analyzed using hypothesis test and gain calculation. The result of this study that there are significant differences in student's habits of mind score between before and after being applied the web-oriented constructivism instruction approach, and if based on the results of gain calculation, it was found that the most student an increase in the medium on gain category. Other than that, if judging from the contributes a web-oriented constructivism instruction approach to habits of mind category it was found the results of a very good interpretation.

The purpose of this research is to explain the role and process of stage management in the implementation of dance performances in the Final Project Examination for S-1 Dance. To achieve this goal, researchers need to apply the principles of performing arts management, including design, organization, leadership, and supervision. The results achieved in this study are a description of performance governance that runs smoothly, effectively, and on time. Dance creators, dancers, artistic supporters (make-up and clothing, set/property, lighting), music (sound system) are able to work together in accordance with their respective artistic designs so that they can be well appreciated by the test team and the audience. Keywords: governance, laboratory, performance, management, dance.

Modernization of waste processing through Waste-to-Energy has been a new trend to solve waste management and energy scarcity. This model however it may raise a conflict with recycling activities. This article establishes a methodological approach to assess Non-Recycled Waste for Refuse Derived Fuels materials. The approach is simulated by using calorific value of waste from Semarang Landfill which has calorific value 5,500 to 6,070 kcal/kg and waste composition of Banjarmasin Landfill which has been classified according to recycling perspective. The simulation shows that a low recycling rate (25% plastic and paper taken for recycling) will produce 3,882 kcal/Kg while a high recycling rate (50%) will produce 3,793 kcal/Kg. This simulation successfully calculates that non-recycled waste materials are still potential for RDFs materials.

Literacy of science is very important to be mastered by each individual to be able to adapt to the progress of science and technology in the future. One attempt to improve the ability of science literacy through the analysis of textbooks lessons. The type of research used is descriptive, by collecting data in the form of documentation study. The sample in this research is several pages of analyzed books taken in a random way using multistage sampling technique. The results show 21% of the book presents the aspect of science as a way of thinking. The aspect is presented on the entire theme of the book with various values. In themes 1 and 2 this aspect is often presented that is equal to 71%, and 51%. The following findings show that Book Y simply presents aspects of science as a way of thinking. In other words, Book Y is enough to emphasize material that supports the mastery of the process.
