Efforts to fulfill food security to anticipate population growth in Indonesia need to be supported by universities through research and community service. The application of the Natural Animal Audio Organic Growth System (NA-AOGS) with a STEM (Science, Technology, Engineering, and Mathematics) approach is an effort to help the community increase crop yields and accelerate the growth of soybeans (Glycine max (L.) Merill). The research method used is R&D (Research & Development) which is modified from Cennamo and Kalk (2018). This model is in the form of a spiral cycle using 5 (five) main activities as follows: (1) defining the product conceptual; (2) designing research products; (3) demonstrating the product in a limited trial; (4) developing the product through the process of evaluating the test results, and (5) presenting the product to the public.  The direct impact of learning is the improvement of science process skills and critical thinking of students participating in the Biophysics course at the Natural Sciences Study Program, Universitas Negeri Yogyakarta. This is due to the effective application of STEM to link science learning with contextual technology and engineering (NA-AOGS), environmentally friendly technology (only using natural animal sound frequency variables), mathematical elements in data analysis, and analysis of soybeans plant growth charts. The economic impact of this research is the scientific contribution in the form of adaptation of agricultural technology so that it can increase soybean yields (an increase of 130.38% on an area of 2750 m2). The novelty and contribution of this research is the integration of science learning with agricultural techniques and technology with a STEM approach so that it can improve the welfare of farmers in educational institutions as a new model in science learning.

This article aims to describe empirically and theoretically the role of science process skills as a basis for learning high-level thinking skills. Science process skills are skills that are able to answer the demands of learning in accordance with the principles of constructivism related to the nature of science learning which is divided into three categories, namely (1) basic science process skills, (2) intermediate science process skills, and (3) science process skills high. Science process skills are claimed by many experts as the basis for developing high-level thinking skills. Activities such as (1) observation allow a person to be open to inquiry and be sensitive and willing to observe, (2) comparison, (3) classification, (4) measure, (5) communication, (6) inference, (7) prediction , (8) hypotheses, and (9) define and control variables, are activities in science process skills that are indispensable as basic skills to be able to think higher through integration in the learning process. High-level thinking skills such as critical thinking, creative thinking, and problem solving can be built through science learning that emphasizes the process. Critical thinking skills which are reflective processes in analyzing and evaluating information to determine one's beliefs and behavior can be built through creative processes that are lues, flexible, original, and precise in the stages of problem solving identification, planning, implementation and reflection.

The purpose of this research are to knowing the differences of critical thinking skills using interactive module photoelectric effects  with printed module, describe the improvement of students' critical thinking skills after the interactive module is applied, describe science process skills in students who use interactive module of photoelectric effects, and knowing student responses to the use interactive module of photoelectric effects. The study was conducted in Natar 1 Public High School, in the even semester 2018/2019 academic year with research design nonequivalent control group design.The research instrument used was a questionnaire (questionnaire), Student Worksheet (LKPD) along with observation sheets and test questions. Data collection techniques were carried out by test techniques, questionnaires and LKPD contents. The data analysis technique of critical thinking ability is done by normality test, homogeneity test and N-gain. The data analysis technique of science process skills is done by calculating the average grade of the class then adjusted to the index classification table of science processes. Hypothesis testing is done by Paired Sample T Test and Independent Sample T Test. The results of the study show that (1) the application of the photoelectric effect interactive module is able to improve students' critical thinking skills, this is seen from the N-gain value and paired sample t test results, 2) there are significant differences in critical thinking skills between students who use interactive modules with printed modules, this is seen from the differences in the n-gain values of both classes and the results of the independent sample t test, (3) the value of students' science process skills is 82.6 with a high category, and (4) students gave a positive response to the utilization of the photoelectric effect interactive module.

The purpose of research are 1). To know are differences in science process skills of students with the applied of inquiry training learning model and direct instruction learning models, 2). To know are differences in science process skills of students who has high critical thinking ability and the  critically low ability, 3). To know the interaction inquiry training learning model and critical thinking ability toward students science process skills. The samples in this research conducted by cluster random sampling and  as many as two class , the first class (X-I) as experiment applied Inquiry Training learning model and the second class (X-2) as control class applied Direct Intruction learning model. The instrument used in this research is tests science process skills and critical thinking skills in the form of description and observation sheets science process skills. From these results it can be concluded that: 1) there are differences in students science process skills with applied inquiry training model and direct intruction model, 2) science process skills of students with high critical thinking ability is better than the science process skills of students with the ability to think critically low, and 3) the interaction inquiry training learning model and critical thinking ability toward the science process skills.
