Abstract. This research is motivated by the lack of critical thinking skills of fourth grade students of SDN Tanjung III, Subang district. On the basis of the need for repairs done either by applying the model of SAVI (Somatic, Auditory, Visualization, Intellectual). So the purpose of this study was to determine the increase critical thinking skills of students in Social Science before and after applying the model SAVI, the performance of teachers in applying the model SAVI, activities and students' response to the model SAVI. The method used in this research is the CAR (Classroom Action Research). Subject of research that fourth grade students of SDN Tanjung III by the number of students as many as 23 people. The instrument used was LKS (Student Worksheet), observation sheet of students and teachers as well as student questionnaire responses. From these results, it can be concluded that by applying the model in study SAVI social science with social problems in the local environment can enhance students' critical thinking skills. The result can be seen from the percentage of the overall level of mastery learning increased from 52.2% in the first cycle, 78.3% in the second cycle and 100% in the third cycle. The average grade class of students increased from 44.3 prasiklus of data with less criteria, up to the third cycle, which reached 91.3 with the criteria very well. With the improvement of students' critical thinking skills that are calculated based on the n-gain of 0.53 with the criteria of being in the first cycle, and 0.65 with the criteria of being on the second cycle, and 0.81 with the high criteria of the third cycle. The results of observations also showed that the ability of teachers and students' activity in applying the model of SAVI increased. Based on questionnaire responses, 100% of students showed interest in learning social science model with SAVI. Therefore, it is suggested that teachers use models SAVI to enhance the critical thinking skills of students so that students used to learn to analyze problems well.

This study aims to detect the ripeness of melinjo fruit using digital image method. Structured identification or division using image processing and computer vision requires the socialization of patterns based on training datasets. Melinjo (Gnetum gnemon L.) is a plant that can grow anywhere, such as yards, gardens, or on the sidelines of residential areas, as a result, produces melinjo into a plant that has relatively large potential to be developed. The process of image processing and pattern socialization is a highly developed research study. Starting based on the process of socializing an object, or a structured division of the object and about detecting the level of fruit maturity. The structured division process regarding ripeness into 3 classes, namely: raw, half-cooked and ripe where the process is carried out using Google Collaboratory which processes the RGB color space to HSV. In this study, the testing method for the system that will be used is a functional test where the test is carried out only by observing the execution results through test data and checking the functionality of the system being developed. The level of accuracy obtained from this study is 98.0% correct.

Makanan bergizi, seimbang, dan sesuai dengan kebutuhan tubuh masing-masing individu, harus diperhatikan. Terutama bagi balita yang membutuhkan asupan gizi untuk pertumbuhan dan perkembangan, akantetapi makanan yang berlebih atau melebihi kebutuhan balita perlu untuk dihindari. Kondisi ini dapat mengakibatkan anak mengalami kelebihan berat badan dan obesitas. Penelitian bertujuan untuk melakukan estimasi besar potensi kerugian ekonomi akibat ketidakhadiran kerja pada balita obesitas ketika dewasa di Indonesia. Penelitian ini merupakan penelitian deskriptif dengan mengolah data dari berbagai instansi terkait serta merupakan data sekunder tahun 2013. Rumus estimasi kerugian ekonomi berasal dari penelitian Pitayatienanan et al., tahun 2014 dan faktorkoreksi. Hasil penelitian menunjukan kerugian ekonomi akibat ketidakhadiran kerja karena obesitas pada balita secara nasional 0,003% - 0,004% dari total PDB Indonesia. Ketidakhadiran kerja karena obesitas terlihat seperti bukan sebuah masalah, akan tetapi hasil estimasi ini menunjukkan dengan meningkatnya ketidakhadiran kerja dapat menghambat berkembangnya suatu negara karena berdampak pada ekonomi dan sumber daya manusianya.

Micro, small and medium enterprises (MSMEs) have an important and strategic role in national economic development. Purbalingga Regency has an area of 777.64 Km2 consisting of 18 Subdistricts with contours of the region which mostly consist of mountains, access to communication and dissemination of information regarding the existence of job vacancies, Micro, Small and Medium Enterprises (MSME) products are absolutely necessary so that the existence of Micro, Small and Medium Enterprises (MSMEs) can improve the standard of living and the economy and equalize employment, especially in the Purbalingga region. The application made in this study is an android based application that can be used by entrepreneurs in the Purbalingga region to register their MSMEs and inform and process job vacancies. The application developed based on the REST (Representational State Transfer) architecture is proven to facilitate the process of data exchange between platforms and systems.

The purpose of this study was to determine the effect of the application of Value Clarification Technique (VCT) to ecoliteracy and critical thinking skills of elementary school students in learning Social Science. The method used in this study is a quasi experimental design with non-equivalent control group design, using the two study groups. Subjects in this study were students of class IVSDN Cijerah Indah, Bandung Kulon District Bandung City.

This study aims to build an information system that can support companies in making decisions, especially regarding sales assessment at PT. Pachira Distrinusa. This is motivated by the difficulty of determining whether or not a sales person deserves an efficient value, because the system is not yet computerized and employee data documents are piled up. In this study, the data used are assessment data at PT. Pachira Distrinusa and the method used is the Naïve Bayes Classifier algorithm. And to find out how well the Naïve Bayes Classifier algorithm is used in this study, the RapidMiner calculation is used to perform the test. From the test in RapidMiner, the accuracy value is 91.67% and the ROC value is 0.979, which means that the Naïve Bayes Classifier algorithm is very well used in this study. After testing using RapidMiner software and getting the test results, then it is implemented into a system using PHP and MySQL which is designed to predict sales assessments. The prediction results obtained from the system are in accordance with the calculation results obtained from RapidMiner calculations and manual calculations. Based on the research that has been done that the decision support system built can be applied to PT. Pachira Distrinusa so as to make it easier to determine the feasibility of the sales assessment at PT. Pachira Distrinusa efficiently.
