Determining the gravity reference point in the form of the absolute gravity acceleration value is necessary for education and research purposes. Department of Physics, Universitas Syiah Kuala (USK), has had the Scintrex CG-5 gravimetersince 2013 and should have had one absolute gravity point around the campus. A new gravity reference point was made at the Tugu Field (Lapangan Tugu) USK, which was derived from the gravity reference point BMKG Mata Ie with an absolute gravity value of 978102.87 mGal. First, we measured the relative difference in gravity’s value between the two points using the Scintrex CG-5 gravimeter. The difference of gravity value at the Tugu Field with BMKG Mata Ie is 23.8356 mGal smaller so that the absolute gravity value is 978079.01 mGal. The result is consistent with the geological data where the rocks around BMKG Mata Ie are metamorphic rocks that began to form in the late Jurassic, while the strata at the Tugu Field consist of young alluvium in the Holocene epoch which has a lower rock density. To verify the absolute gravity value, it is compared with the gravity value obtained from the satellite TOPEX. Data from these satellites is around 978140.15 mGal with a difference of 61.14 mGal.

Indonesia is one of the largest coal producer countries in the world. In the previous research, it is stated that coal producer countries are able to affect economic growth. The purpose of the study is to investigate the cointegration and causal relationships between coal consumption and income in Indonesia for the period of 1965- 2016 using Granger causality test based on Vector Error Correction Model (VECM) employing population as the control variable in bivariate system. The Augmented Dicky-Fuller (ADF) and Phillips-Perron (PP) tests were used to determine the variable stationarity. From Johansen’s co-integration tests, it is indicated that there is a long-run relationship between the variables. The empirical study shows that there is no causal relationship between coal consumption and economic growth in Indonesia since coal consumption in fact cannot affect economic growth in Indonesia. Export tax becomes government revenues earned from energy sectors including coal.

Kullu Halal (all Halal) is a concept that is highly applied in the Middle Eastern andNorth African (MENA) region as the majority of the population is Muslim. Manyproducts from non-Muslim countries are also exported to the MENA countries andsome of them are exposed to animal-based ingredients. Halal certification studies in theMENA region are found to be quite minimal to non-existent. The paper is designatedto analyze the effects of Halal certification towards the purchase intention of Muslimconsumers on food products from Muslim majority countries in the MENA countries.Theory of Planned Behavior (TPB) was used as a platform to predict the consumers’intention to purchase the Halal certified products. A self-administered questionnairewas selected as a method and the respondents are the Muslim consumers living incertain areas of Klang Valley, Malaysia. Five hundred questionnaires were distributed,and 417 questionnaires were considered usable. Structural Equation Modeling (SEM)was used as a method in this research. Attitude, Subjective Norm, and PerceivedBehavioral Control showed a strong correlation with Purchase Intention and the resultswere statistically significant at p < 0.05. Algeria was found to be the least trustworthycountry by the respondents, followed by Iran, Lebanon, Iraq, and Bahrain. The resultsindicate that the presence of Halal certification is important and will be profitable for thefood industry players in the MENA region. Despite being Muslim majority countries,it is important to ensure the presence of Halal certification in the products from MENAcountries, especially from those that received low scores in the country of origin study.

After Palu Earthquake that occurred on September 2018, another moderate earthquake on April 2019 with 6.8 Moment Magnitude (Mw) at a depth of 17 km occured in Banggai Islands. The earthquake occurred on the shallow depth that generated by an active fault with horizontal mechanism on the Banggai’s tectonic system. To explain the tectonic system in the Banggai Islands, we present a well-calculated 1-D velocity model by solving the coupled hypocentre-velocity inversion for 385 local earthquakes that recorded by BMKG regional network. The earthquakes was selected based on azimuthal gap, minimum number of stations and root mean square of travel‐time residuals. Technically, the fit solution are simultaneously inverted for total 81 inital models and will give an unique final model. The model is constructed by using Velest program that analyse the fit velocity model from body wave traveltimes (P and S wave), together with station corrections. The final 1-D velocity model will be very useful to conduct another high precision relative relocation and make a focal mechanism inversion.

The rheology of a material especially related to mechanical behaviour is an important characteristic. Rheology has wide applications for example in nanomaterials, engineering design, biology, and in a large scale case in geodynamics study. Rheology relies on several physical equations such as continuity equation, momentum equation, gravity potential, state equation, heat transfer, and advection equation. The equations seem to be simple, however, the application of those equations to a real case is not easy and causes many numerical problems. Marker-in-Cell (MIC) is a technique to solve a numerical rheology modelling problem especially diffusion of sharp gradients during the advection process. The technique successfully simulates the advection process for thermomechanical viscous material for a 2-dimensional case study. The model was initially set up two parts with laterally contrast difference of material characteristics. The lateral density difference of material induced gravitational force and generated circular movement of material. After the simulation was run for the 20-time step, the whole material moved more clockwise circulation. The model started to be stable when all denser material at the lower layer and lower density material at the upper part. The model was fully stable and become at a stationary state at a time more than 100-time steps. The final simulation result showed that the MIC algorithm successfully simulated the conversion process involving the thermomechanical mechanism with diffusion error control and without breaking the contrast density of the material.

The topic of static and dynamic electricity is an abstract concept and relatively difficult for students to understand, especially in a case when the students were only taught about the electricity as a concept of electrical current, by means of the flow of electron, using analogy, without accompanied by practical experiments. This study aims to develop a lesson in the topic of dynamic electricity in an interesting and easy to understand approach using appropriate learning media that accompanied the abstract concepts with the real practical experiments. We used the equipment of ELVIS II+ (Engineering Laboratory Virtual Instrumentation Suite) from National Instruments to achieve the aforementioned goal. Props were designed to support various basic and advance dynamic electricity experiments. Selected topics relate to basic competencies 4.2 mandated by the ministerial regulation No. 24 in 2006 issued by the ministry of education and culture of the Republic of Indonesia (Permendikbud No. 24, 2016) exemplified by the capacitor charging and discharging experiments. It is expected that the activities would become interesting for the students since they were conducting the engineering process during the experiments that provided a fun learning. The more interesting part of the experiments was the understanding of concepts of science obtained from applying mathematics to solve differential equation problems. The application of mathematics appeared naturally when students constructing and solving the differential equations in order to understand the science behind the electrical phenomena. The most fascinating part for the students occurred when they can successfully proofed the solutions to differential equations with experimental results. Integrating the whole STEM (Sciences, Technology, Engineering, and Mathematics) components in the learning approach is proofed to be the key to the slogan of “learning is fun”. The experiment syntax followed the Investigation Sciences Learning Environment (ISLE) model so that the learning processes will develop thinking ability as prospective researchers in students.

The development of technology in the 21st century is so rapid both in the field of sensor and data communication. In fact, almost all smartphones have used the technology. In addition to using cutting edge sensor technology, smartphones are also equipped with internet communication features so they can be categorized as IoT (Internet of Things) devices. However, both of these technologies have not been optimally used as a media for learning physics. This paper discusses the use of MEMs (Micro-electromechanical system) sensor (ADXL-345) to detect the oscillation of the spring-mass system. Data obtained by MEMs is read by IoT based Microcontrollers (NodeMCU EPS8266) and directly transferred to the intranet WIFI network via the UDP (User Datagram Protocol). The data transmitted in the UDP packet is received by a computer that is integrated with LabVIEW, a user-friendly software that is based on a Graphical Programming. Students were encouraged to conduct several experiments to investigate the dependence of the period of the spring-mass system on the mass, the spring constant, and the amplitude. The oscillation of the spring-mass system received by the computer recorded the amplitude and the period of oscillation. Then students will compare the data from various observational experiments to predict the relation among the variables. Finally, they tested their prediction by conducting a testing experiment. This learning model is using ISLE (Investigation Sciences Learning Environment) syntax where students constructed their knowledge about mechanics, especially about spring-mass system, and enjoyed their discoveries as scientists did. Since the learning media has used technology and also carried out engineering process stages and involved the calculation of mathematics to understand the measurement results, it can be said to have used the STEM (Sciences, Technology, Engineering, and Mathematics) approach. We observed that an atmosphere of “learning is fun” existed during the lesson.

In a process of learning, learning media play an important role in improving students’ understanding. In this study, a learning medium based on Internet of Thing (IoT) was developed. The IoT is one of core development in technology of Industrial Revolution 4.0 era. The learning media developed in this research study utilizing LoRa (Long Range Area) which functions as a remote data sender. The LoRa paired with Arduino connected to sensors and placed in several location within Banda Aceh. LoRa was integrated with Network Thing to store data and could be displayed on the PC. The researchers and students could observe the changes in air quality in relation to the changes in temperature, humidity, and air pressure from the data that have been stored in the Network Thing cloud. The students are motivated in the learning process to find out relationships between air quality and changes to the temperature, humidity, and air pressure. This is preliminary and ongoing research. The early data were collected from interviews with students after the learning process and collecting the results of the observation. Students’ interest increases with the integration of Science Technology Engineering and Mathematics (STEM) in the learning process. This was demonstrated by students during the learning process. From this learning process, students are also aware of the importance of reducing air pollution. Around 86% of students understand the concepts of subject learned and around 92% of students were motivated and enjoy during the learning.

The results of data analysis, with the product moment correlation technique, show that there is a correlation of positive and significant relationship between learning styles and student learning outcomes in physics course. In addition, the results of the study also showed that the greatest contribution of learning styles to learning outcomes was in analytic and holistic learning styles.

This paper reports a qualitative inquiry to investigate the application of the Investigative Science Learning Environment (ISLE) approach as a framework for teaching and learning physics. The aims of this study are to investigate how ISLE processes are applied, what the perspectives of instructors and students on the ISLE approach are, how the ISLE approach could be possibly applied in the physics courses and other STEM courses in Indonesia. Participants in this inquiry consist of the inventor of ISLE, three ISLE instructors, and students in an ISLE lab session. We used qualitative case study method and narrative data analysis in the process of evaluating data from observations, interviews, and ISLE-based learning materials and publications. It was found that the ISLE approach was applied smoothly in the class and lab sessions. The ISLE instructors are those who believe in the philosophical and epistemological reasoning behind the framework and the importance to nurture students’ scientific abilities. Some students liked the ISLE approach, some didn’t. Those who liked ISLE found that they enjoyed the process of thinking and discussing in learning. It is very likely to apply the ISLE approach in Indonesia for physics courses, but it will be challenging for other subjects.

The purpose of this article is to discuss the results of developing several test and non-test instruments to be used as a measurement of learning outcomes, questioning skills and students’ inductive thinking skills. Development using the ADDIE model. Based on expert assessments and trials on a limited sample, 20 items were obtained for the learning outcomes instrument, 12 items for the non-test question ability and 10 items for the non-test instrument inductive thinking ability.

Finally, we apply Support Vector Machines as the classifier and 10-fold cross validation are performed on the Bosphorus database. Using our approach, 3D facial points yields a better performance than 3D facial distance measurements and 3D facial surface normal in 3D Facial AU recognition.

The purpose of this study is to detect the presence of gelatin in orthodontic dental materials for halal authentication. The detection of gelatins was done using Fourier Transform Infrared Spectroscopy with Attenuated Total Reflectance (FTIR-ATR). In this study, 21 samples were included and the spectrums were generated by OMNIC software of Nicolet iS50 FTIR. All data were also subjected to similarity match (SM) using TQ Analyst software. Four types of gelatin tested, namely porcine, bovine, fish and commercialized gelatin. From the studies, it was found that no samples exhibit similar spectra as the gelatins tested and SM found that no samples showed 100% similarities with porcine gelatin.

It is recommended for a novice to engage a trained and experience person, i.e., a coach before starting an unfamiliar aerobic or weight routine. The coach's task is to provide real-time feedbacks to ensure that the routine is performed in a correct manner. This greatly reduces the risk of injury and maximise physical gains. We present a simple image similarity measure based on intersected image region to assess a subject's performance of an aerobic routine. The method is implemented inside an Augmented Reality (AR) desktop app that employs a single RGB camera to capture still images of the subject as he or she progresses through the routine. The background-subtracted body pose image is compared against the exemplar body pose image (i.e., AR template) at specific intervals. Based on a limited dataset, our pose matching function is reported to have an accuracy of 93.67%., Presented at The International UNIMAS STEM Engineering Conference 2018 (ENCON2018).

The Investigative Science Learning Environment (ISLE) is an approach that encourages students to be active, creative and innovative in learning Science including Physics. The ISLE based STEM method helps students in solving real-life problems and involving collaborative group activities. Many students assume that learning Physics is difficult but with the ISLE-based STEM approach, the students will learn Physics theories and concepts with ease and fun. This is in line with the Indonesian government program to enhance the students' literacy and capacity in Science, Technology, Engineering, and Mathematics (STEM) among high schools and undergraduate students in Indonesia, This study has utilised the ISLE based STEM module and approach for teaching Physics concepts to the high school students at four selected senior high schools in Banda Aceh, the capital city of Aceh province, Indonesia. The results of the study were encouraging and it would leverage and enrich the current state of knowledge related to the learning Physics and Science concepts.

This study aims to enhance teachers’ competence in conducting Classroom Action Research (CAR) in order to improve their professional services in handling the teaching and learning process. The researchers’ preliminary observations found that many teachers were still lack of competence in conducting correctly classroom action research following the guidelines, though some of them have conducted it several times. This problem is caused mostly by the factor of research proposal which is still unrecognazible. The qualitative method was applied in this study through training and intensive counselling on how to design CAR. The research findings focused on the qualification of research proposal in terms of language aspect and theoretical aspect. The language aspect focuses on sentence construction, paragraph construction, the use of language in the chapter of introduction and the chapter of theoretical bases. The theoretical aspect focuses on the accuracy of selection of theory, and the variety of theoretical sources. It is found that 25 % of CAR proposal contains recognizable sentences based on the form of S-P-O-K1-K2, 75 % of the proposals are recommended to be reviewed, 50 % of proposals contain regonizable paragraphs in terms of cohesion, and coherence. In the aspect of theoretical accuracy, 75 % of proposals contain theories which are in line with the research problem, and 25 % of proposals should be revised. Moreover, more than 95 % of proposals still depend on the books as the source of theory and only 5 % of proposals which cite from journal. It is concluded that the teachers’ competence in using scientific language must be improved and the source of theory must be upgraded through citing from recommended journal.

This study aims to describe the understanding of junior high school through the application of an environment-based learning approach to the material of environmental problems. The method refers to students’ understanding of three indicators (translation, interpretation, and extrapolation). The subject was determined by purposive sampling of 63 students from three junior high schools in the city of Bengkulu, Indonesia. The collection technique is essay test. The results of the study are: (1) the ability to translate student translation 74 (Good), interpretation of 71 (good), and extrapolation 83 (very good), (2) the percentage of three indicators of student understanding, namely 37% translation, interpretation 31%, and 32 % extrapolation, (3) the overall level of student understanding is 14%, both 68% and very good 18%. The understanding can be categorized as good in ecosystem learning. The conclusion of this study that learning with an environmental approach has a positive impact on understanding junior high school students.

The purpose of this research is to find out the effectiveness of using CLL in teaching speaking at the first grade students of SMP N 18 Mataram in academic year 2014 / 2015. This is kind of quantitative research with quasi experimental method. The population of this research involved 67 students’ from the first grade in SMPN 18 Mataram. The reseacher took 44 students as a sample that divided into two groups, 22 students belong to the experimental group and 22 students belong to the control group. To find out the differences of x and y, the writer used pre- test and post- test to collect the data. The data collected was analized by t-test formula. Therefore, the writer gave different treatment to prove that CLL is better than conventional method. After the writer gave the treatment, it showed that the mean of post test of experimental group is higher than control group. After that, the result of mean score of Experimental and group is proved by the t-test and compared with t-table, so the result in t-test is 3,8 and t-table (0,05%) is 2,02 and (0,01 %) is 2,70. In addition, the result of the t-test is higher than t-table (3,8 > 2.02 > 2,70). This means that there is significant different between experimental and control group. From the explanation above, the writer concludes that Community Language Learning (CLL) was effective in teaching speaking for the first grade students of SMP N 18 Mataram in academic year of 2014/2015.
