The significant influence of the 21st century brought a change in Physics learning. Students are required to have the skills to think, work, and live in the surrounding environment. To achieve 21st-century skills needed teaching materials that can support the learning process.With the presence of teaching materials, students are more active in building their knowledge and easy to understand the material provided. Teaching materials that can guide students with a productive task to practice is the student worksheet. A student worksheet is a teaching material that contains a set of activities to maximize students understanding in achievement of competence. To improve the competence of students, one of the efforts that teachers to develop quality student worksheet. A student worksheet is considered qualified if has validity criteria. The validity assessment of the student worksheet is carried out by expert reviews.

STUDI AWAL RANCANG BANGUN COLORIMETER MENGGUNAKAN SENSOR OPT101 BERBASIS SISTEM ANDROID DENGAN DISPLAY SMARTPHONE Habibi Putra; Yulkifli Yulkifli

Colorimeter is a color measuring device that is a tool that can distinguish colors based on the value of the output produced. In this study a colorimeter device was made using the OPT101 sensor, an analog sensor based light detector. OPT101 sensor has characteristics if the intensity of light received is getting brighter, the greater the sensor output value and vice versa. Because of the characteristics of the sensor like that, this sensor can be used as a measuring instrument to determine the concentration of a food coloring agent. This study aims to look at investigating the relationship between the concentration value of a dye solution to the OPT101 sensor response value contained in the colorimeter tool. The dyes used are red (metile red) and blue (brilliant blue) with 10 different variations of concentration, with a range of 0.01% -0.1%. After the measurement experiments were carried out on the sample, the results obtained were almost the same as the theory, namely the relationship between the concentration value was inversely proportional to the value of the sensor output. The inverse relationship means that the more concentrated a dye solution is, the more the light intensity penetrates the substance or dims. So that the OPT101 sensor detects a dimmer light source, the sensor output value gets smaller, because the relationship of the sensor output value is directly proportional to the intensity of the received light. Based on the measurements that have been made, the results of sensor response values are obtained for the red sample with a range of data from 276,698 decreasing to 240,762, while for the blue sample from the range 9,828 it decreases to 8.75. The value for the blue sample is much smaller because the blue sample is much thicker than the red sample.

Indonesia is an archipelago prone to disasters such as floods hydrometeorologi. The impact posed by floods almost every year has increased both from loss of life, property or damage to public facilities. One of the causes of the large number of casualties happened i.e. lack of knowledge or understanding of the disaster. So the effort to reduce the impact of the flood disaster that is through education that is integrated with the material glut. This is in accordance with changes in education standards suggesting that the structure of the curriculum for the education unit was the appropriate education with potential local or excellence an area. One of the potential areas that are owned by the province of West Sumatra is disastrous floods. However, the fact there has been no real outstanding textbooks that have been integrated with the material of the flood. So the need for analysis of the suitability of the material science material with flooding. Before integrating the material into a flood of material need for the science analysis of the suitability of the material of the science on a textbook lesson in IPA with the purpose of the curriculum, for the Government's efforts in revising the curriculum lead to changes of national standards Education so that changes the structure and arrangement of the material in the textbook lessons. Then the results of the analysis of the suitability of the material science with the goal of this curriculum is to be used as an ingredient or material that will be seen the suitability of material science material with flooding. Type of this research is descriptive research with qualitative approach. The subject of this research is a textbook lesson in science class VIII semester 1 in books K and E. sampling Technique used was purposive sampling. Instruments for collecting data consists of sheets of material suitability analysis IPA with the goal of curriculum textbook lessons IPA SMP/MTs class VIII semester 1 and sheet material suitability analysis IPA with the material glut. The research results obtained are the suitability of a textbook lesson science SMP/MTs class VIII semester 1 with the goal of curriculum to book K obtained percentage for compliance 79.36% (accordingly) and the book E obtained percentage conformance 88,57% (very appropriate) . Then the level of conformity of the material science class VIII semester 1 with the flood of material on KD 3.1 is inappropriate category with 26.67 KD 3.2 is 66.67% with appropriate categories, KD 3.3 is 20% with a category is not appropriate, KD 3.4 and KD 3.6 are 33,33% with categories is inappropriate, KD 3.5 was 46,67% with quite appropriate category.
