In the revised 2013 curriculum, students are required to have skills that fit the challenges of the 21st century. To train these skills is to apply the right model in learning, namely the guided inquiry model. The availability of guided inquiry models in learning can be seen from the lesson plans. All lesson plan at public high schools has not been identified whether they have a guided inquiry model. Therefore, this research aims to find out the availability of guided inquiry models in lesson plan Physics grade XI Semester 1 in high schools. This research is descriptive research with a qualitative approach. The population data in this study are all lesson plan Physics High School grade XI semester I used by 15 districts in West Sumatra. The samples in this study were lesson plan Physics in high schools grade XI Semester I from 7 schools created by teachers. Based on the research that has been done, the availability of the guided inquiry model in lesson plan physics grade XI semester 1 obtained the results of the analysis that lesson plan with the highest availability category is lesson plan 3 with a percentage of 83.3% in very available category. The lesson plan with the lowest availability is lesson plan 1 and lesson plan 6 with a percentage of 16.67% in the unavailable category. Thus, it can be concluded that the availability of the guided inquiry model in the lesson plans for grade XI semester 1 is categorized as sufficient available.

This research is motivated that the teaching materials used can not activate the students. The teaching materials used are printed materials containing materials, sample questions and evaluation. These teaching materials make learners memorize the formula instead of mastering the concept. This study aims to produce products such as CSP and LKPD oriented guided inquiry on a matter of momentum and impulse in Physics valid, practical, and effective. This research is a research development (research anddevelopment) using 4D development model. The model consists of four phases: define (definition), stage design (design), develop phase (development), and disseminate stage (dissemination). However, this study is only done until the stage of development (development). The data of the research are analyzed by qualitative and quantitative analysis. Based on the research that has been done, the product produced in the form of RPP and LKPD oriented guided inquiry. Product research is categorized as very valid aspects and LKPD completeness RPP, RPP eligibility and LKPD contents, use of language and LKPD RPP, and kegrafisan LKPD using guided inquiry learning model component with an average value of 93.4 to 93.7 for the RPP and LKPD. Products are categorized very practical research by teachers with an average value of 88.4 to 86.9 for the RPP and LKPD, as well as practical by learners with an average value of 82.9.

Blood sugar levels are a major factor of diabetes. Diabetes is a one of a dangerous diseases caused by damage to the working system of the hormone insulin in the body’s metabolism. The diagnosis of blood sugar levels is generally by pricking a finger or arm to take a sample of the patient’s blood. Another method can be used without hurting the patient’s body, which is using a urine sample. Discoloration of the patient’s urine can be detected using the TCS230 color sensor and photodiode. The design of the tool system in this research uses the changes in the color of the urine specimen as a measurement parameter. This research aims to determine the performance and design specifications of the manufacture of blood sugar levels based on the level of urin turbidity using the TCS230 color sensor and photodiode. There are two research results. First, the result of performance specifications is a beam-shaped measuring device consisting of an object box measuring 8,5x6x8 cm3 and an electronic component box measuring 20x10x10 cm3. Second, the result of design specifications are the precision of the tool at 95,95% with a percentage of errors of 4,44% and accuracy of 99,25%.
