Abstract
The experiential learning process is a relevant method used to enhance understanding of the field and the critical thinking skills of learners. Futher more, technological developments improve students learning needs. In this case, learners are required to be able to learn and work dynamically by combining the concept of critical thinking and the way of life as demand for the 21st century. Therefore, dynamic learning and the ability to improve the cognitive and collaborative abilities of learners in their interactions with the environment and all changes are indispensable. This research aims to spread the educational game quiz Assistance to create fun and dynamic learning for students. In addition, developed media is expected to improve cognitive ability and critical thinking learners, especially in higher education. The development of this educational game is done in the economic field so that the material to be presented is a basic course of economics faculty. To measure the success of this game-based learning, researchers used 100 samples from three majors (development economics, management, and accounting). This method of analysis uses the method of gain-scores, where the learning outcomes of experimental class with learning game treatment and control class learning outcomes are examined and analyzed to determine their effectiveness. Results from analyses showed that use of game-based learning is highly effective for improving learning outcomes.

Abstract. Objectives - This study aims to develop lectures on mechanics based on multiple representations using field dependent and field independent cognitive styles (MR-FD & FI), in understanding the mastery of the concept of mechanics. In the context of physics learning based on multiple representations is to combine two or more representations as forms in widely used to understand and convey physics concepts. Cognitive style can be divided into two, namely: dependent field cognitive style (FD) and independent field cognitive style (FI). The third semester student research subjects numbered 21 students from a university in Jakarta Indonesia. The instrument used consisted of a content module that contained 4 gravity mechanics and central force (GGS) content, particle system dynamics (DSP), rigid object rotation (RBT) and rigid object rotation in three dimensions (RBT3D) that had to be filled in and student worksheets (LKM) in which there are questions that students work on. Methods - Descriptive quantitative and qualitative research are carried out to get a clear picture of MR implementation using FD and FI cognitive styles. Findings- The results showed that most students have a field dependent (FD) thinking style seen in the post-test results on GGS material 61.90%, RBT 61.90%, DSP 57.14% and RBT3D 57.14%. For independent field thinking (FI), the results of post-test results were 42.86% DSP, RBT 38.10%, RBT3D 38.10% and GGS 33.33%. It is concluded that students thinking styles can change from thinking styles that were initially field dependent (FD) can change to field independent (FI) this can occur due to various factors, including; 1) Health conditions, classrooms and students focus; 2) The level of difficulty and ease of conceptualization of the material being studied; 3) Basic math and physical abilities. Research Limitations - Limitations in this study involve only subjects from small classes from one university, so the results are not strong enough to represent the overall situation, this can be a way to conduct further research with more and more diverse subjects. Originality- This study is the first to map the understanding of the concept of mechanics based on multiple representations using the FD and FI cognitive styles. The results of the study find new discoveries, where all students have a cognitive style of either FD or FI.

Abstract
Middle group rare earth elements, such as Gadolinium, have an important role in a variety of applications, mostly used in high-tech industries because they have good mechanical strength. However, the rare earth elements of this middle group are difficult in their analysis because each element has almost the same physical and chemical properties. Gadolinium is one of the rare earth elements that has high paramagnetic properties. The purpose of this study was to determine the gadolinium content by differential pulse voltammetry using an experimental design. Plackett-Burman experimental design was used to obtain selected factors that have positive results to the method. A total of 11 factors that have the potential as the main influence in this study were selected at the highest (+) and lowest (-) levels, and then measured 12 times according to the Plackett-Burman experimental design. Furthermore, an optimization was carried out with the Box-Behnken experimental design by performing 15 measurements to obtain the optimum conditions for each factor. Response data was processed and obtained factors with optimum conditions, deposition potential of -2.0 V, modulation of amplitude of 0.1 V and deposition time of 120 seconds. The detection limit and the quantitation limit were 3.97 mg / L and 10.71 mg / L, respectively. The recovery of Gadolinium was 95% that is satisfactory.

Abstract
Enhancing Students- Activeness and Concept Comprehension and Teachers- Perception on Teacher Quality Improvement through Lesson Study Rusdi Hasan, Nasral Tanjung and Yani Ernawati Dept. Biology Education, University of Muhammadiyah Bengkulu, Indonesia Corresponding author: rusdihasan@gmail.com Abstract Lesson study (LS) originally developed in Japan with over a century is a form of teacher inquiry in which teachers in small groups undertake collectively a cycle of “plan-do-review/see” activities to improve pedagogy and so pupil learning and progress. LS has been practiced in many countries worldwide as well as developing countries in South East Asia region. This paper reported the implementation of LS on enhancement students- activeness in classroom and concept comprehension in biological class as well as teacher-s perception on improving their quality as LS applied. The study was employed in Senior High School Muhammadiyah 4 in Bengkulu located in Southern Sumatra of Indonesia. We used cooperative learning model in three cycles of LS practice of this study. Each cycle consisted of three steps i.e. Plan, Do and See. The results showed that students- activeness during LS in cycle I were 1.9% of excellent, 46.3% of good, 50.6% of fair and 1.2% of poor. The students- activeness were better in cycle II become 7.4% of excellent, 56.2% of good, 36,4% of fair and 0% of poor. In cycle III students- activeness rise to 11.7% of excellent, 71.6% of good, 16.7% of fair and 0% of poor. Students who had excellent and good categories collectively increases from 48% to 64% and 83 % in cycle I, II and III, respectively. In contrast, students who had poor activity decrease from 1% to nil in cycle I to the next cycle. LS made lesson process better and better and enjoyable by students. It was mirrored by student-s comprehension on biological concept in term of Reproduction in human in this study was increased from 64.2 to 75.8 and 82.7 in cycle I, II and III of LS, respectively. Those results reflected that LS implementation improved students- activeness on biology lesson and concept comprehension in biology. On the other hand, all teachers evolved in this study perceived that LS implementation can improve teachers- professional quality and promote teachers professional development. They strongly agreed that LS to be beneficial for them to become a better quality biological teacher.

Abstract
The objective of this study was to examine pre-service physics teacher understanding related to physics content knowledge by investigating the relationship between knowledge of the Basic Electrical Concepts (BECs) test and the student-s certainty in their physics knowledge. Data was collected from 57 preservice physics teachers with the BECs test and Certainty of Response Index (CRI) values. The BECs test with CRI was administered to pre-service physics students following accomplishment of a unit of study on electricity and simple circuit. The results of diagnostic test were classified into correct and incorrect answers, and CRI values were classified into certain and uncertain. High CRI value in incorrect answer on the BECs test implied that 26% preservice physics teachers had misconceptions about basic electrical concepts. Low CRI value in correct or incorrect answer on the BECs test indicated there were 53% preservice physics teachers providing the answer by guessing; due to no understanding or confusion about their understanding. There were 21% preservice physics teachers providing the answer correctly on the diagnostic test with high CRI value. It was concluded that the majority of preservice physics teachers (79%) were either guessing or had misconceptions about every item related to the electric basic concepts.

Abstract
Geometry becomes a difficult subject for students. The abstract object was one of the factors. Therefore, more concrete learning media were needed. One of them was augmented reality assisted by GeoGebra. The purpose of this study was to determine the ability to understand the geometrical concepts of high school students through augmented reality learning assisted by GeoGebra. Treatment was given to students through learning using GeoGebra-assisted augmented reality. This was a quasi-experimental study with a pre-test post-test control group design. This research instrument was a test of the ability to understand the concept of geometry. The test was used to measure students initial abilities, and this was referred to as a covariate. Also, to measure the ability to understand concepts after students follow augmented reality learning assisted by GeoGebra. Data were analyzed by covariate analysis (ANCOVA). The results of this study were F = Fo (A) = 9,150 with p-value = 0,000 <0,005. That means, there were differences in the average ability to understand the concept of geometry between those taught with augmented reality assisted by GeoGebra and conventional controlled by covariates. Other results show that t = 6.723 with p-value = 0.000 <0.05. This shows that the ability to understand the geometry concepts of students taught with augmented reality assisted by GeoGebra was higher than students who were taught conventionally after controlling for covariates. The conclusion was that the ability to understand the concepts of geometry through GeoGebra-assisted augmented reality learning was better than students taught with ordinary learning.

Abstract
The concept of physics can be applied to aspects of customs and culture in order to preserve local wisdom. One way to introduce the customs and culture of the local area can be done by studying traditional houses. Jambi traditional house is one of the local wisdoms that every generation needs to know. The foundation structure of the Jambi traditional house uses wooden poles arranged to support the weight above where. Mass of each pole has a correlation with the amount of load that has been distributed evenly. The purpose of this study is to analyze and explain the application of physics concepts in the foundation structure of traditional Jambi houses and to build character education to new generation. The process of collecting data is done by interview, observation, and documentation. Based on the data analysis, it is shown that the mass of each pole is strong enough to support the live and dead load that has been analyzed. Because it has a pole mass greater than the distributed load. So this can educate the new generation to know the process of making foundation structures that are done with certain calculations that can be analyzed through the concept of physics.

Abstract
We used the seedling emergent method using the soil sample itself to study of the vegetation change and regeneration strategy after flooding in river ecosystem, the effect of prescribed burning and grazing on wetland vegetation in Blanket Bog moorlands, UK, and the spread of alien invasive plants during road constructions. In the river ecosystem, it has a low similarity between above-ground vegetation and soil seed banks. However, there are species have been found only in soil seed banks without above-ground vegetation, therefore the soil seed banks are regarded to support biodiversity. In addition, the formation of soil seed banks and ground-level vegetation in the stream has been simplified after the flood, but it has been studied that the flood functions to maintain the native vegetation of the stream as the number of aquatic plants has increased. The Blanket Bog moorlands in the UK are well-developed peat layers that play an important role in controlling the global carbon concentration. In the second study, we proposed the appropriate intervals of prescribed burning to maintain Sphagnum species, the main species forming peat layers, and the Calluna vulgaris community, which provides important ecosystem services. Finally, the dispersal trend of alien invasive plants along the road was studied using the hand sorting seed count method. The alien invasive plants introduced during the road construction and they tend to spread according to the movement of the vehicle and the road conditions. We found that the unique ‘tubular- structure of the road enables the long-distance dispersal in a relatively short time. As such, the study of seed banks in the soil can be applied in various ways, providing a clue to the solution of phenomena occurring in the ecosystem. There are considerations, such as the inability to identify all seeds in the soil samples and the fact that the dominant above-vegetation species may differ from the soil seed bank in an ecosystem. However, there are advantages such as providing information for predicting potential vegetation, and it takes relatively short time with less than 4 months, in common, to evaluate.

Abstract
Sustainable development goals mandate all countries struggle to reduce tuberculosis (TB) incidence by up to 90%. One of the essential efforts for eliminating TB is doing preventive behaviours. This study aims to explore TB prevention behaviour and associated factors. This is a cross-sectional study carried by rapid survey method. We involved 210 residents of Rancakasumba village, one of the highest TB prevalence location in Bandung district. Data regarding behaviours and related determinants were obtained through a validated questionnaire. We analysed the data using STATA 13. As many as 51% of respondents have good TB prevention behaviour. The least common preventive behaviour is exercising regularly (19%), while 64% of respondents had done the most crucial preventive behaviour which is closing the mouth when coughing. Based on the chi-square test, the level of education and knowledge was the only factors that significantly related to prevention behaviour (p <0.001). While gender, occupation, income, and experience getting TB education did not have a meaningful relationship. It can be concluded that more than half of respondents have practised adequate TB prevention efforts, and there is a significant relationship between the level of education and respondents knowledge about TB with TB prevention behaviour.

Abstract
The production of the sugar industry is increasing from year to year because of the national sugar production and consumption. In order to achieve the level of production that can meet these needs, the government has requested a national sugar self-sufficiency policy. Estimation of sugarcane production has a big influence on the companys policy considerations to determine further production results. This study aims to predict the production of sugar cane that will be obtained by the Asembagus sugar factory for the next five years. The data used to predict are data from 1989 to 2018 obtained from secondary data from Asembagus factory registration results. The method used is the Box-Jenkins ARIMA method by comparing the measure of forecasting results with the trend and exponential smoothing methods. The appropriate forecasting result is the ARIMA model (1,1,1) because it has a smaller error value than using other methods. Forecasting results for 2019 are 42055.6 tons in 2020 predicted 43222.9 tons in 2021 predicted to produce 44090.7 tons, in 2022 predicted 44788.2 tons and in 2023 predicted sugarcane production of 45389.2 tons.

Abstract
According to Sutopo, Head of the BNPD Data, Information and Public Relations Center, the earthquake disaster that occurred in Palu, there were 1,948 fatalities, 843 missing, and it is estimated that many victims were buried in the estimated figures until they reached thousands (BCC Indonesia, 2018). The losses suffered are also estimated to be very large. Preparedness is one part of the disaster management process and in the current developing concept of disaster, the importance of preparedness is one of the important elements of pro-active disaster risk reduction before a disaster occurs. (LIPI-UNESCO, 2006). The object of this research is the people of Palu who live in Temporary Resettlement in several locations, namely Petobo, Balaroa, Silae, Lero, and Kampung Baru. This study uses economic modeling methods to determine the relationship between variables and as many as 150 people are sampled in the collection of data needed. The variables of this study are age, education, occupation, and aspects contained in the disaster risk reduction index (Carreno et al., 2004). The conclusion is that age is very influential on emergency response planning and implementation of warning systems as well as community preparedness and training, on the other hand education and employment have no effect at all in the DRR index. Therefore, there needs to be an evaluation from both the local and central government, the community, and academics to think about ways to reduce disaster risk by increasing public knowledge of disasters.

Abstract
In the rural development discourse, culture is explained as a process for economic development but also factors that can hinder economic development. On the one hand, the culture is able to bring solidarity and shared desire in encouraging rural development so that culture is understood as a collective product of society which reflects shared attachment among the community. On the other hand, the existence of traditional values and cultural norms makes the community slow to accept innovation as well as unwilling to innovate. The understanding of the role of local culture in rural development based on empirical studies has received less attention. This study seeks to explore the uniqueness of the local culture and its role in rural development. Qualitative research is applied to understand the complexity that occurs by using a single case study approach and applying in-depth interviews with key informants. Then, the qualitative content analysis method is used by studying and analysing communication systematically and objectively to the messages that appear by paying attention to the context. In the process, data selection and reassembling processes are carried out to interpret the meaning contained in the message or text. We found that culture has an important role in village development. The culture was formed from local knowledge which is passed down from generation to generation and also the experience of the community. The unique history of society influences the values of the culture itself. Interaction and local culture were able to create economic opportunities for rural development.

Abstract
The current reality still found school counselors who are less familiar with computer applications. It became a fundamental consideration for the development of e-sociometry by utilizing formulas and macros in Microsoft Excel. E-sociometry is stored using the XLB file extension so that the file size tends to be smaller and compatible with macros. Spreadsheets and tab buttons are modified to make user-friendly use and look easier. E-sociometry is used to measure the level of social relations of students in the class that refers to specific criteria. The developed e-Sociometry has tested on school counselors in Indonesia. School counselors in Indonesia who have used e-sociometry give positive feedback on the idea of making this application.

Abstract
Regional development is a strategy of utilizing and combining internal factors (strengths and weaknesses) and external (opportunities and challenges) that exist as potentials and opportunities that can be utilized to increase the regions production of goods and services that are a function of the needs both internally and externally. These internal factors are in the form of natural resources, human resources and technological resources, while external factors can be opportunities and threats that arise along with their interactions with other regions. The comprehensive spatial planning and development of the region certainly needs the support of information on the potential and constraints of the region with its own genetic background as a whole, meaning that all complete information about all aspects relevant to the spatial needs are met. Information for spatial planning includes potential including physical-mechanical properties of various types of rock masses. Leles is one of the sub-districts in Garut regency which has an area of 6.5 million hectares with a large potential of mining excavation. Regional Spatial Planning Arrangement based on the potential of mineral excavation ensures mining plans in the area do not kill other potentials and shows conformity to the plan long-term. Mountain sand eruption excavated as an industrial commodity is the biggest potential in the Leles region. The existing constraints are related to earthquakes and volcanic eruptions.

Abstract
Fuel is a main staple consumption of the industry, especially in Indonesia which is an industrial zone. The worlds fuel availability comes from fossils only remaining about seventy years, Indonesia is expected to stay for another fifty years the fuel reserve will be depleted. Fuel utilization in Industrial ERA 4.0 focused more in the supply chain distribution of goods and services, ranging from supply actors to the consumer. Distribution utilizing gasoline-fueled vehicles to transport goods and services, where the role will be increasing in the future. With regard to the phenomenon, It is important to find a New solutions for generating fuel, to support the development activities of goods and services distribution. Gasoline is one of the most common fuel types used, to support the distribution of goods and services. One component of gasoline subtitution is ethanol or methanol that can be produced from pineapple peel, through the fermentation process into a fuel called bio-fuel. In this study will be discussed about the usefulness of pineapple peel, as an alternative to the future shortage of gasoline fuel solutions. The condition is supported with pineapple availability, which placed In the thirteen provinces in Indonesia, With plantation land reaching two million hectares. Analytic Hierarchy Process (AHP) is used to see the skin value of pineapple, that converted into petrol fuel by the public, by observing the culinary dimension of the service, reliability, responsiveness, assurance, empahaty, and tangible. The results of research that took the area in West Java especially Subang regency, show that the community in plantation areas, have not had the awareness of utilizing pineapple as fuel, both for household and industrial activities. The phenomenon is demonstrated by low responsiveness, assurance and emphaty weights, so it is important that people are given a value awareness that can be obtained, of pineapple peels as a value added garbage as an alternative to fuel solutions, to fulfill the needs of household or industrial-making of pineapple dodol, in addition to reducing organic waste derived from the industry dodol pineapple, that available so much in the environment in which they live.

Abstract
Moral Rights are perpetual rights to protect a work from distortion, mutilation, modification of a Work that are detrimental to its self-honor or reputation. However, there is no creator parameter if it suffers a loss from its honor and reputation. In general, the community perspective considers that "habits" are part of freedom of expression. The primary substance "everyone shall have the right to freedom of expression" becomes a bastion as a form of self-actualization or displaying its expression in public. This study aims to identify the limits of the right of integrity in moral rights in relation to freedom of expression by comparing the protection of moral rights in Indonesia, France, America, and Germany. This research is a normative juridical study with the statue approach, conceptual approach, and comparative approach. The research specifications used are descriptive-analytical. Data collection techniques using the library research method. The results of the study show that the limitations for users of other peoples creations in Indonesia adhere to Article 27-29 of the Electronic Information and Transaction Law (ITE Law) and Article 43-50 of the Copyright Law which governs the principle of fair use. The results of the comparison of the regulation of Moral Rights in Indonesia, France, America, and Germany show similarities in regulation. The equation is a consequence of the ratification of the Berne Convention by meeting minimum standards of protection. However, there are fundamental differences due to the influence of state policy factors that consider copyright a derogable right (rights that can be reduced or restricted by the State). America is more focused on the principle of expediency by prioritizing the economic rights of the creator. In contrast to Indonesia, France, and Germany, where there is a balance between economic rights and the moral rights of the creator.
