Abstract
This study aims to analyze the understanding of the concept of projectile motion of students in class X who studied with modeling instruction accompanied by embedded formative e-assessment. An embedded experimental design was used in this mixed method study. This study involved of 30 students of Malang public high school consisting of 12 male and 18 female students. The main instrument of this research was 9 materials (items) with multiple choice questions. N-gain and effect size analysis were carried out on the test results, while the student’ answers and reasons were analyzed qualitatively. The results showed that the average of pre-test value was 18.87 which increased to 49.93 in the post-test, the N-gain value was 0.50 (upper medium) and effect size was 2.09 with a category greater than the standard. This means that with modeling instruction accompanied by formative e-assessment could improve students’ understanding of the concept of projectile motion. It was also found that there is some difficulties in describing the direction of acceleration each time in moving an object with a parabolic path.

Abstract
The results of the preliminary survey indicate that there are still many students who have not been able to solve the problem, the learning is still teacher-centered. For this reason, problem based and project based learning is implemented. The research aims to determine the differences of the student learning outcomes using Project Based Learning (PjBL) and Problem Based Learning (PBL) models in terms of self efficacy. The design of the research was quasi-experiment with 2×2 factorial design. The population is fifth-grade students of Elementary School (SD Kartika 1-11) in Padang, Indonesia. Sampling was done by cluster random sampling technique. The research instrument was a learning outcome test and questionnaire. Data were analyzed using two-way ANOVA. The results showed that: (1) the learning outcomes of students using the PjBL model were higher than the PBL model, (2) the learning outcomes of students who had high self-efficacy were better than low self-efficacy, (3) there is no interaction between learning models with self-efficacy on student learning outcomes.

AbstractThis paper explain about the effects of the collaborative-think pair share project based learning model on learning outcomes of student on the subjects of the auxiliary machine. In this study the twelve grade students of the Commerce Ship Engineering department, SMKN 10 Padang has been considered as research population. The research method is a quasi-experimental. The sample consist of two classes: the first one is an experimental group (EG, n = 21) with collaborative-think pair share group project based learning model. The other one is the control group (CG, n = 20) with conventional learning model. The results of the study show that the use of collaborative-think pair share project-based learning models can improve student’s learning outcomes significantly compared to the conventional one. The collaborative-think pair share project-based learning model is more effective than conventional one in improving students’ learning outcomes, especially on the vocational high school in Padang.

Abstract
This study intended to develop the entrepreneurial characters of UNNES Chemistry students through the implementation of Natural Product learning integrated with Ethnoscience and STEM (Ethno-STEM). This research is a descriptive-qualitative study subjected to Chemistry education students who joined the Natural Products and Chemical Entrepreneurship course. The research subjects were introduced to the project-based learning integrated with Ethno-STEM concerning concepts related to terpenes, steroids, flavonoids, and alkaloids; also, the introduction of natural chemical isolation and distillation processes both in the community and laboratory. The students were assigned a project of chemical batik production, i.e., batik with chemical structure patterns followed by evaluation and assessment. There were six best batik designs proposed to one of the traditional batik centres named “Zie” to be printed by using batik printing machine. These designs are said to be worthy of production; in other words, they are valued economically. The research results indicated that the Natural Product learning integrated with Ethno-STEM was able to well develop the students’ mastery concept of chemistry, creative and innovative thinking, perseverance, and conservation of national culture.

Abstract
Natural Animal Sound Spectrum Characterization based on Fourier analysis is a undamental scientific study of the spectrum of natural animal sounds that can be used as a stimulator of growth and productivity in food intensification. The results of characterization are very useful for adding scientific treasures in the field of biophysics, especially to support the use of natural animal sounds as stimulators of growth and productivity of food crops through spectrum analysis based on Fourier analysis so that it has a strong theoretical basis to be developed into an applied industry in the field of food intensification. Natural animal sound spectrum is obtained by recording animal sounds naturally in nature by using a voice recorder. Furthermore, the sound of these natural animals analyzed their spectrum characteristics using Adobe Audition to determine the peak frequency produced. Sound spectrum characterization which has peak frequency sonic bloom between 3000Hz - 5000 Hz is made as an audio stimulator for growth and productivity of food crops. From various 27 sources of animal sounds recorded and analyzed, there are 17 types of animals that have frequency peaks in range sonic blooms (3000-5000 Hz) and can be produced into stimulators and 1 combined stimulator. While the results of the sound timbre analysis of each animal has a frequency range including: 1-1000 Hz a number of 6 animals, 1000-2000 Hz of 8 animals, 2000-3000 Hz a number of 14 animals, 3000-4000 Hz a number of 12 animals, 4000-5000 Hz is 2 animals, and 5000-6000 Hz is 4 animals.

Published: December 2019

Abstract
The use of a reference manager (RefWorks, Mendeley, EndNote, Zotero) has become very important in the writing of scientific papers for students and lecturers. The Faculty of Economics of Semarang State University (FE UNNES) has called on students to use a reference manager when composing a thesis. This study aims to analyze factors that influence the utilization of reference managers by FE UNNES students. The theories used are the Unified Theory of Acceptance and Use of Technology (UTAUT) and the Theory of Planned Behavior (TPB). The research population was students working on their theses at FE UNNES. The data collection method used is a questionnaire distributed online to respondents through the Google platform. The data analysis method used is path analysis. The results show that performance expectancy and social influence have positive and significant effects on a student’s intention to use a reference manager. Meanwhile, effort expectancy is not proven to have a significant effect on a student’s intention to use a reference manager. Effort expectancy, performance expectancy, and social influence have a significant effect on the use of reference managers. Other results show that behavioral intention, lecturer guidance, and policy pressure do not significantly influence the use of reference managers. The results of this study demonstrate that the use of reference managers by students is more influenced by perceptions of their usefulness. That is, students assume that the use of a reference manager is a necessity.
