RSUD Salatiga is a hospital that already has a wastewater treatment plant, but has not been able to process all the waste generated. Wastewater treatment plant will be designed to process wastewater from the installation of nutrition, laundry, PONEK, pavilion and classroom III. WWTP capacity will be made at 120.4 m3/day with the type of anaerobic-aerobic biofilter treatment. Processing to be used consists of control boxes, tubs fat separator, equalization basin, tub anaerobic decomposition, initial deposition basin, anoxic biofilter, biofilter aerobic, final settling basin and bath indicators with the disinfection process. Later, when the new WWTP has been made, the existing WWTP will be retained so that the hospital will have two WWTP Salatiga.

This study aims to describe the cognitive elaboration models of students in the process of abstraction of concepts and principles of two-dimensional mathematical space in Class XI of Las Teknik SMK 1 Curup. This research uses a qualitative approach. The main instrument is the researchers themselves guided by student ability test sheets and interview guide sheets. Data were analyzed through three stages, namely the stage of data reduction, data presentation and drawing conclusions. Research result; description of students' elaboration models in the process of abstraction of mathematical concepts in two-dimensional space: Recognizing models; Students are clearly familiar with the shapes of two-dimensional spaces, Students can understand the definition of two-dimensional shapes of two-dimensional space objects given, and based on information that students have obtained previously. Students can determine the objects that constitute the building of two-dimensional space. Students can discover the principles of building a two-dimensional space Model Building With; Students can discover the relationships of concepts and principles of two-dimensional geometric shapes by analyzing images of two-dimensional geometric objects. Model Contracting; Students know what concepts will be used, and to know these concepts students imagine and sketch a two-dimensional space object of the existing problems, in solving these problems associated with the incorporation of mathematical principles contained in the concept, and the student's knowledge according to students' ability to remember. Conclusion, through the concept of cognitive elaboration in the process of abstraction of principles and mathematical concepts of two-dimensional space students are able to use mathematical concepts and principles in solving problems so students are able to make conclusions from the results of the settlement and students are able to explain or present the results of their work.

This study aims to analyze the process of abstraction of students of class XI IPA 2 of SMA Negeri 6 Lubuklinggau in understanding the concepts and principles of geometry in terms of Van Hiele's theory. The method used in research is a qualitative method. Data were analyzed through three stages, namely the stage of data preduction, data presentation and conclusion drawing. The results of data analysis obtained from the five steps of thinking based on Van Hiele's theory that the thinking of students of class XI IPA 2 of SMA Negeri 6 Lubuklinggau is only at stage 0 to stage 2, whereas for stage 3 and stage 4 the level of thinking of class XI IPA 2 students Lubuklinggau still has difficulty in drawing conclusions from things that are general to things that are specific and at this stage is also a stage of thinking that is high, complicated and complex. Conclusion, the level of thinking of students of XI Science 2 of SMA Negeri 6 Lubuklinggau is still low in understanding the concepts and principles of geometry in terms of van hiele's theory.

The purpose of this study was to develop student worksheets (LKS) using the Lubuklinggau city-based Contextual Teaching and Learning (CTL) on the set material in class VII according to the 2013 curriculum and find out the quality of worksheets developed from the validity, practicality and potential effects of using LKS. The research method used is Research and Development (R&D) research. Development of worksheets using a 4-D model that was modified to a 3-D model. This model consists of 3 stages, namely: the stage of defining (Define), design (Development) and development (Develop) without including the spread (Disseminate) due to time constraints. The results of the study are based on the assessment analysis by the three experts namely: linguists, material experts, and media experts showing that the worksheet fulfills valid criteria with an average score of 3.12. While the results of the analysis of student response questionnaire assessments obtained that the student worksheets meet practical criteria with an average score of 3.55 and have a potential effect of 27 students (84.37%) whose grades reach mastery learning, while 5 students (15.63%) not reached mastery learning. In conclusion, the development of student worksheets using the contextual Teaching and Learning (CTL) based on the city of Lubuklinggau is declared valid, practical and has a potential effect on students' mastery learning. Keywords: Contextual Teaching and Learning, Student Worksheet
