Previous studies suggested that real-world problems and studentsâ€™ characteristics should be emphasized when designing statistics teaching materials. ELPSA Framework could address those considerations and was used as a learning framework for teaching statistics to junior high school students. Prior to classroom implementation, the teaching materials was tested and deemed valid and practical. Pilot implementation results showed that the teaching materials was effective for learning statistics because the ELPSA framework components facilitate studentsâ€™ understanding of statistical concepts. Students also perceived learning based on the ELPSA framework positively because it enables them to enjoy the learning process.

This paper discuss the impact of dispersion and non-linear terms combinations the surface wave equation particularly on the peaking phenomena of the wave water that initially in the form of a bichromatic wave. The study for both of these terms are focused on the position where the bichromatic wave experience its highest peaking and its related bichromatic amplitude amplification. In the previous study, the position where the bichromatic wave experience its highest peaking is of order and its bichromatic amplitude amplification is of order , where and are the amplitude and frequency of the bichromatic wave envelope, respectively. This result is based on the fifth order Korteweg de Vries (KdV) equation and the quantity that obtained is called Maximal Temporal Amplitude (MTA). However, despite the the position where the bichromatic wave experience its highest peaking suits the result of Stansberg experiment and the result of numerical calculation using HUBRIS, its related bichromatic wave amplitude amplification is not close enough. The source of this discrepancy is suspected from the dispersion and non-linear terms of the KdV equation used. This study shows that the existence of the dispersion and non-linear terms influences the position of Maximal Temporal Amplitude (MTA) and its bichromatic wave amplitude amplification. For the coefficient of dispersion term of 1.0065 and nonlinear term of , the position of MTA and bichromatic wave amplitude amplification suits the result of Stansberg experiment and the result of numerical calculation using HUBRIS

This study aims to determine solution of Boussinesq equation which is approximated by using asymptotic expansion method. Nonlinearity of Boussinesq equation causes the solution is not easily determined, so the solution is approached through its linearity. This method is in the form of power series expansion up to third-order, where each term of the series is linear. Furthermore, the finding solution is compared with the solution that was found by Mohyud in previous study. The result of this comparison showed that there were similarities of the two solutions. However, differences occur in phase as modeled in the solution of each method

This study aims to determine the ability of students in understanding of graph based on interpersonal and logical mathematical intelligence. The approach used in this research was mixed methods by using the stepwise mixed model especially sequence explanatory model. The subjects were six students on grade XI of MAN 1 Banda Aceh selected based on students who have interpersonal and logical mathematical intelligence. The results showed that student’s graphics ability with high interpersonal intelligence was in fair criteria, the student was able to translate the graph, but not yet able to interpret and extrapolate the graph. A student with medium interpersonal intelligence had good criteria in understanding the graph when viewed from the ability to translate and interpret the graph, but still made mistakes in interpreting the graph. The ability to understand graphics of low interpersonal students was in good criteria that was shown by smoothly translating graphs, being able to interpret graphs, and being able to extrapolate graphics appropriately. Student’s understanding of graphs of high mathematical logical intelligence was at excellent criteria that were showed by being able to translate graphs, being able to interpret and extrapolate graphs. The ability of understanding graphics in students with medium mathematical logical intelligence was having good criteria means that students are fluent in translating the graph but still lacking in interpreting and extrapolating the graph. Student understanding of graph with low mathematical logical intelligence had inadequate criteria, meaning that student was only able to translate graphs on some translational indicators.Keywords: interpersonal intelligence, logical mathematical intelligence, mathematical understanding.

The research in this thesis was done to examine the model of traffic flow of volcanic disaster evacuation path for uphill and downhill roads. The assessment was focused on the area of disaster evacuation path from the Pante Raya Bener Meriah intersection to Takengon. This model is assessed for two different types of time when which a disaster occurs; the disaster occurred at night and the disaster occurred during the day, especially during peak hours (working hours). The model was developed with attention to the exixtence of inflow and outflow along the evacuation route. Furthermore, the model obtained is solved numerically by using finite difference method. The chosen approach of this method is upwind scheme with time and space steps using forward difference and backward difference. The solution of this model in the form of simulated vehicle density along evacuation pathways. The research conducted is in the form of a model of traffic flow on evacuation paths and restricted to the inflow and outflow without alternative path as well as the conditions of the road which are uphill and downhill, showed a high density of vehicles either at night or during the day. Uphill road conditions resulted in decreased vehicle speed and vehicle density will increase, while downhill road conditions resulted in increased vehicle speed and vehicle density will decrease, meaning that the road conditions which are uphill and downhill will greatly affect the process of evacuation. Degree vehicles of evacuation efficiency occuring at night without an alternative pathway produces a high efficiency so that it can be interpreted that the evacuation process in the evening was successful and runs better than the evacuation process during the day, and this is caused by the existence of vehicles on the road evacuation process started thus affecting the efficiency levels. Keywords : Traffic flows, finite difference method, upwind scheme method, forward difference, backward difference, greenshield method, uphill road, downhill road.

Penelitian ini membahas tentang simulasi kontrol optimal model dinamik perokok dengan melibatkan harga dan parameter fungsi dampak kenaikan harga. Pengaruh harga rokok terhadap pengurangan konsumsi rokok ditinjau melalui dua kasus yang berbeda yaitu kasus dengan fungsi dampak kenaikan harga secara linear dan logaritmik. Adapun tujuan dari penelitian ini yaitu mengembangkan model jumlah perokok dengan melibatkan harga rokok dan mendapatkan solusi optimum pada model jumlah perokok dengan meminimumkan jumlah perokok berat dan perokok kadang-kadang melalui kenaikan harga rokok. Model yang digunakan yaitu model jumlah perokok dengan dinamika akar kuadrat yang terdiri dari empat kompartemen, yakni perokok potensial (), perokok kadang-kadang (), perokok berat () dan mantan perokok (). Model ini menggunakan interaksi antara perokok potensial dan perokok berat dengan melibatkan harga rokok. Model dinamik perokok dengan fungsi kenaikan harga secara logaritmik lebih baik dalam mempertahan perokok berat dari pada model dengan fungsi linear, sedangkan model dinamik perokok dengan fungsi linear lebih cepat dalam menurunkan jumlah perokok berat daripada fungsi logarithmic. Kenaikan harga yang ideal untuk menurunkan jumlah perokok di Indonesia adalah 66,67%.

Students are still less involved in the teaching and learning process in class in mathematics. Lack of student involvement resulted in students' problem-solving abilities being weak. Constraints faced by students included difficulties in building plans, errors in operationalizing plans, and wrong conclusions. The purpose of this study was to determine student involvement in terms of students' mathematical problem-solving abilities in mathematics. This study uses a descriptive qualitative research approach. The subjects in this study were 12 students of class XII IPA-2 at MAN 4 North Aceh. Data collection techniques used in this study were observation, interviews and documentation. Data analysis techniques using data reduction, data presentation, and drawing conclusions. The results of the study show that in general high problem-solving abilities are also accompanied by high involvement, and vice versa. However, students in the high group have not been involved in finding answers, exploring variations and sorting information, and making inductions. Medium group students have not been involved in classifying, exploring variations and expressing in their own words and finding answers, sorting information and making inductions. Meanwhile, students in the low group were only able to clarify, associate and generalize, use previous knowledge, create mathematical objects and provide examples.

Spatial ability is the ability to imagine, compare, predict, determine, construct, present, and find information from visual stimuli in terms of spatial context that involves manipulation and mental rotation. Students in rural and urban areas have different ways of looking at a problem, especially with regard to spatial. Many opinions state that there are similarities and differences between boys and girls in terms of spatial ability in urban areas, but there is no information about the conditions between male and female students in rural areas. This study aims to describe the spatial ability of junior high school students in rural areas in terms of gender differences. This research is a descriptive research with a qualitative approach. Taking research subjects using snowball sampling technique. The research subjects were six people in one of the junior high schools in Bener Meriah Regency, Aceh Province. Data was collected by means of tests and interviews. Data analysis used qualitative data analysis techniques, namely: data reduction, data presentation, and drawing conclusions. The results showed that the tendency of male students' spatial abilities included five abilities, namely spatial perception, spatial visualization, mental rotation, spatial relations, and spatial orientation, while female students only included four spatial abilities because female students did not meet the mental rotation indicators. In general, both male and female students have difficulty in solving problems related to spatial relations indicators. Therefore, in learning, teachers need to develop students' spatial abilities, especially those related to spatial relations in rural areas, as well as develop abilities with mental rotation indicators, especially for female students.
