<![CDATA[Research on the manufacture of lightweight brick with basic material waste processing of goldin the province of West Nusa Tenggara has been done. This research is very important because most of the people in NTB separate gold by amalgamation and cyanidation methods. Processes that do this will result in hazardous waste on the environment so that the need for countermeasures. The purpose of this research is to create a lightweight bricks made of waste processing of gold which has a strong press that meets national standards. This research was conducted through two stages, namely 1) Stage of light brick making, 2) Phase compressive strength test light brick production. The results showed that lightweight bricks made with waste raw gold processing and cement with a ratio of 3: 1 has a compressive strength of 7.80 kg / cm2. These results demonstrate compliance with national standards, namely 7.83 kg / cm2 so that the product of this research can be said to be feasible.]]>

<![CDATA[This research aims to know the existence effect of AIR (Auditory Intellectually Repetition) learning approach with the demonstration method toward the communication and critical thinking ability. This research includes the experimental research (pretest-postest only control group design) with a populations that are all of students grade VII SMPN 8 Taliwang with number of students 40 peoples, sample of this research there are two class, where class of VII A as a experimental class and class VII B as a control class. Analysis technique used t-test, ttest for critical thinking abilities 3,64 greater than ttabelis 2,15, communication skills obtained tvalue(3,33) thantTabel(2,15). Cause the value ttest is greater than ttabel then Ho is unaccepted and Ha accepted, this means the use of AIR learning approach with the method of demonstration has effects on improvement of communication and critical thinking ability in class of VII SMPN 8 Taliwang.]]>

<![CDATA[Formative assessments developed by teachers are generally conventional. One of the most common constraints on conventional formative assessment is the time to correct the test results long enough, especially for schools with large capacity classes. Therefore the teacher difficulties in providing direct feedback. This paper proposes a computer-based assessment product called ASFORDIASI BEKOM. The application is able to provide formative tests, feedback immediately after conducting tests, and provides remediation materials to help learners learn independently. The design of the study used the Dick & Carey (2001) research and development design which consists of four general stages: preliminary study, preparation, development, and effectiveness test. The study is limited to the third stage of development stage. Based on the validation and trial results of the product, BEKOM ASFORDIASI is considered feasible if used for learning especially on temperature material and calor grade VII SMP.]]>

<![CDATA[This study aims to develop a 'learning module' identification of material content based on research and local wisdom. This module is a refinement of the Material Physics module. This course is an option; therefore the content tends towards the development of talent and interest to motivate the Master's degree. During this study more based on literature studies, the means are very limited. As a result, many curiosity and student awareness can not be missed because learning through research is very limited. The development of research-based modules and local wisdom can support the needs of students to conduct research. The research method used in this research is R & D research using Borg & Gall development model including product analysis, development, expert validation and revision, small field trial phase, large scale field trial and final product result. Learning module on subject matter identification of research-based materials and local wisdom as a product of development.]]>
