Abstract
Abstract. In recent years, many studies have shown that chemical reactions are concepts that are difficult for students to understand so they can cause misconceptions. The purpose of this study was to determine the conceptions, threshold concepts and troublesome knowledge in chemical reaction from previous studies and from interviews with chemistry teachers. This study uses qualitative methods and document analysis. Based on analysis of journals and interviews, there are a number of correct concepts, namely: atomic reorganization, breaking and reformation of bonds, and changes in physical or chemical properties. While students misconceptions in the chemical reaction material consist of: ion compounds formed from cations and molecules, cations will bind to negatively charged atoms and vice versa, compounds in solution will be neutral or molecular atoms, and write ions with the wrong charge. Meanwhile, threshold concepts consists of: concept of mixture, physical and chemical properties, material changes, concepts of protons and electrons, electron configurations, forces between molecules, chemical formulas/chemical symbols, chemical bonds, nomenclature of chemical compounds, ionic charges, and Lavoisier law. While troublesome knowledge consists of: the complexity of the particles involved, the complexity of interactions that may occur, the complexity of applying Lavoisiers Law, and the language used.

Abstract
One of the goals of learning science based on the 2013 curriculum is to develop students- reasoning abilities and and lead them to be independent. One form of reasoning abilities is an abductive reasoning which is a process of the best hypothesis that begins with observing facts, proposing hypotheses or making the most reasonable answers. When someone does this process, he is, basically, on the early stages of abductive inquiry process. When students formulate hypotheses, it is possible to formulate the different hypotheses between one student and the other students. This study aims to identify the characteristics of the types of students- abductive in science by implementing the abductive inquiry model (AIM) integrated a connected type to global warming material. This is a qualitative research, the instruments used are audio recordings of student and teacher dialogues during learning activity and observation sheets to captue student abduction type adopted from Shurcz. The subjects in this study were 30 VII grade students in one of the Middle Schools in Lembang who were selected using a purposive sampling. Students are divided into 6 groups and discussed different sub- topics related to global warming material. The results showed that the abductive type of students in science learning using integrated MIA connected types varied among groups; abductive theoretical, existential abductive models and abductive laws or rules. The implications of abductive inquiry learning in science and relevant research are highly recommended with different material.

Abstract
Entrepreneurship is one of the fields where the concept of career has found application as an analytical tool. However, considerable gaps exist in operationalization and measurement of this concept. Using the qualitative in-depth interview which collected from entrepreneurship training participants, this paper addresses some of these gaps. Meanwhile, the need for this research stemmed from the fact that in today-s new world of young generation, the new world of work, organizations and markets are demanding new skill sets, innovative approaches to delivery and increasingly higher performance levels. The impacts of technology and globalization and the demand for entrepreneurs have brought a new era in economies and organizations, resulting in new career realities. The purpose and direction of the young entrepreneurs- career is no longer confined to a single employer boundary. Therein lies the opportunity for young generation to understand, manage and leverage this dynamic context for entrepreneurship career progression and growth through the accumulation and implementation of relevant and valued career capital. This research investigated the three components of entrepreneurial careers for the young generation, particularly in Bandung City, Indonesia. This research examine how entrepreneurial careers are shaped by three components, namely motivations (knowing-why), knowledge (knowing-how), and relationships (knowing-whom). The findings of this research could provide an insightful platform for further research by exploring the presence of those three components in another city around Indonesia.

Abstract
One of the government initiatives to facilitate desired growth in economy is to continue providing tax incentives. Tax incentives will reduce overall tax burden and the excess of the cash flows can be used to finance the growth in capital expenditures and many other investments. Unfortunately, determining a tax incentive-s costs and benefits is inherently difficult because it is unknown if the firm would make the investment without the incentives. Review of recent studies has made progress measuring the tax incentive effectiveness, however, the findings are inconclusive. This suggests that another explanation is needed for the firm-s decisions to take up the tax incentive, i.e., the willingness to ay higher tax instead. This study aims to fill the gap by investigating if the utilization of tax incentive by SMEs within manufacturing sector reduces the overall tax burden measured by effective tax rate (ETR) and significantly reduces earnings management exercise related to tax avoidance practices. Further, this study will also investigate factors associated to the firms with higher tax paid (ETR) to understand is these firms refuse to take up the tax incentives available and willing to pay higher tax instead

Abstract
In 2017, the global recorded music industry players- revenue from music streaming exceeded the revenue from other music formats. It because of music streaming offers many benefits for listeners, which includes high quality, no need for stored devices, a huge array of music library, easy to listen, etc. In order to gain exponential growth of music listeners, the music streaming providers rely on viral marketing. Unfortunately, the elements that construct viral marketing effect are different between one country to another. This research focuses on the Indonesian key elements of viral marketing that drive the music streaming user-s attitudes of JOOX Indonesia (as a popular music streaming provider in Indonesia). The present study collected data by using google form and finally used 455 valid response as respondents. The data then analyzed by using factor analysis and multiple regression. The factor analysis discovered that from four dimensions of viral marketing (i.e. informativeness, entertainment, irritation, and source credibility) only two dimensions emerged, which are: entertainment, and trusted information (as a merged factor from irritation and source credibility). The multiple regression analysis found that both variables were significantly affect the JOOX Indonesia user-s attitudes. Some recommendations for JOOX Indonesia and also for future researches are being discussed in the last section.

Abstract
Accounting firms are increasingly under a great deal of pressure to minimize audit costs and deliver services in more efficient ways while improving the quality of their audit services. This study examines the association between political connection (POLCON), internal audit (IA) investment and arrangement with audit fees in Malaysia. Multiple regression was used to test the models and different tests were employed to enhance the rigor of the results produced. The sample comprised of 2209 firms observations listed in the Main Board of Bursa Malaysia, encompassing three years of data from 2011 to 2013. Overall across all the models, the results show that the majority of the variables exhibit significant association with audit fees. For independent variables, POLCON displays positive significant association with audit fees while both IAs have negative significant association with audit fees. From the firms- and auditors- perspective, the result of this study contributes to the industry and existing literature by suggesting that the agency problems in POLCON firms can be minimized through effective internal control mechanisms. Higher IA investment is associated with higher audit fees in POLCON firms and their external audit fees can be reduced when the IA function is outsourced.

Abstract
The design of sensitive, selective and reproducible biosensors with enzyme immobilisation for analytical application is reported. The study is aimed to develop a versatile and accurate analytical tool to be applicable for the determination of target analytes in real samples. The biosensor device is developed with employ immobilised enzyme as catalyic agent to convert target analytes to product that can be monitored electrochemically. Electrochemical biosensors, both in amperometric and potentiometric detection system have been prepared for different types of analytes. The strategy to immobilise ezyme in a matrix polymer is explained. Analytical performances of the the biosensors have been evaluated based on their detection sensitivity, linearity detection range, limit detection, selectivity, and stability. The enzyme electrode is prepared by immobilization of enzyme throughout polytyramine membrane film and attached tightly onto the surface of electrode. The working electrode was made via electropolymerization of monomer tyramine on an electrode surface from a mixed phosphate buffer/methanol solution containing enzyme at pH 6.0 followed by covalent attachment using EDC/NHS crosslinking agents. The precise control over the charge passed during deposition of the polytyramine polymer allows concomitant control over the thickness of the deposited enzyme layers onto the surface of the electrode. The reproducibility of the biosensors achieved is certainly due to the control of the thickness of the enzyme layer being limited by the resistance of the polytyramine film, and to the enzyme immobilization procedure on to the surface of the electrode. The biosensor showed good stability and to be applicable to determine analytes in real samples. Amperometric biosensor has been developed for the determination of various types of analytes such as glucose, sulfite, and uric acid. Potentiometric biosensor has also been developed with the same procedures for determination of analytes such as malic acid, cholesterol, and urea. The biosensor showed good stability and applicable to determine analyte in real samples.

PBL-STEM class made 3 products, which are camera obscura, magnifier, and binoculars. Scientific Literacy Test was used with 0.88 Cronbach-s aplha reliability. Data analysis with one-way ANOVA, post hoc Tukey test, N-gain, and Cohen-s effect size was conducted. The result showed three classes had significantly different scientific literacy. Scientific literacy of PBL-STEM was the highest, while PBL class is higher than the conventional class. The improvement of both Experiment 1 and 2 belonged in medium category, while the improvement in conventional class was in low category. The effect of operational implementation of Experiment 1-Experiment 2 pair yielded “large” result, and both Experiment 1-Control and Experiment 2-Control pairs yielded “very large” category in the enhancement of students- scientific literacy.

Abstract
This study aims to produce digital teaching materials on the theme of Earthquakes that can improve student STEM literacy. The research method uses research and development with the ADDIE model which includes Analyze, Design, Develop, Implement and Evaluate. Data was collected using expert vakidation sheets, valid questions about STEM literacy were 25 questions with reliability of 0.956, questionnaires for teachers and students, and understanding tests. The collected data is analyzed descriptively and quantitatively. Analysis of the content contained in STEM literacy in student handbooks so far shows teaching materials that have not been charged with STEM literacy (31%). Digital teaching materials designed have been validated by material experts and media with yields of 97.5 and 87.5. The assessment was also carried out by teachers with the acquisition of CVR and CVI of 0.88 and 0.87. The acquisition of student teaching material trials in one to one trial (81%), small group trials (85%) and field trials (86%), and the results of test students understanding of 54%. After being revised, teaching materials were implemented for 32 class VIII students. Before and after implementation, pretest and posttest were carried out with an average gain of 50.75 and 71.00, and an average N-gain of 40%. Based on this, it is concluded that digital teaching materials designed can improve STEM literacy in the medium category.
