Abstract

Penelitian ini bertujuan untuk mengidentifikasi apakah mahasiswa calon guru matematika mampu membangun situasi didaktis matematis pada siswa SMP dalam pembelajaran matematika berbasis ICT (Information and Communications Technology). Penelitian ini adalah penelitian deskriptif kualitatif. Subjek penelitian adalah mahasiswa calon guru yang telah praktik mengajar di sekolah. Subjek menggunakan aplikasi yang dibuat sendiri oleh subjek. Aplikasi yang dibuat berupa Augmented Reality (realitas bertumbuh), yaitu teknologi yang menggabungkan benda maya dua dimensi dan atau pun tiga dimensi ke dalam sebuah lingkungan nyata tiga dimensi lalu memproyeksikan benda-benda maya tersebut dalam waktu nyata. Hasil penelitian menunjukkan karakteristik situasi didaktis dalam pembelajaran matematika berbantuan ICT pada siswa SMP yang dibangun oleh mahasiswa calon guru adalah sebagai berikut: situasi didaktis matematis yang dibangun belum mengonstruksi pengetahuan siswa secara mandiri; situasi didaktis matematis yang dibangun cenderung berasal dari informasi yang disampaikan guru, bukan dari media ICT yang digunakan; dan ICT yang dilibatkan dalam pembelajaran belum mampu mengelaborasikan proses kognitif siswa dalam jejak pembelajarannya. Analysis of a didactic situation in ICT-assisted mathematics learning in junior high school studentsAbstractThis study aims to identify whether prospective mathematics teacher students are able to build mathematical didactic situations in junior high school students in ICT-based mathematics learning. This research is descriptive qualitative research. The research subjects were prospective teachers who had practiced teaching at school. The subjects used applications made by themselves. Those applications were in the form of augmented reality (reality grows), namely technology that combines two-dimensional and or three-dimensional virtual objects into a real three-dimensional environment and then projecting these virtual objects in real-time. The results showed the characteristics of didactic situations in ICT-assisted mathematics learning in junior high school students built by prospective teacher students were as follows: didactic mathematical situations that were built had not constructed students' knowledge independently; the built mathematical didactic situation tends to originate from the information conveyed by the teacher, not from the ICT media used; and ICT involved in learning has not been able to elaborate the cognitive processes of students in their learning footprint.

Abstract

Penelitian kualitatif dengan pendekatan studi kasus ini bertujuan untuk mendeskripsikan ke­salahan mahasiswa semester pertama yang mengambil mata kuliah trigonometri dalam menye­lesaikan masalah kecepatan sudut. Tujuh mahasiswa program studi pendidikan matematika di salah satu perguruan tinggi di Kota Malang menjadi subjek penelitian. Data yang dikumpulkan dalam penelitian ini terdiri atas hasil pekerjaan subjek yang diperoleh melalui tes pemecahan masalah kecepatan sudut dan transkrip hasil wawancara dengan subjek. Analisis data hasil pe­kerjaan subjek dilakukan dengan menglasifikasikan berdasarkan jenis-jenis kesalahan. Sedang­kan analisis transkrip hasil wawancara dilakukan dengan mengodekan kata-kata yang menun­jukkan penyebab munculnya kesalahan subjek. Hasil penelitian menunjukkan bahwa kesalahan mahasiswa semester pertama dalam menyelesaikan masalah kecepatan sudut terdiri dari ke­salahan konsep dan kesalahan prinsip. Faktor penyebab dari kesalahan konsep ini yaitu tidak memahami konsep kecepatan sudut dan faktor penyebab kesalahan prinsip ini yaitu kesalahpahaman bahwa rumus kecepatan linier sama dengan rumus kecepatan sudut. Oleh karena itu, untuk menghindari kesalahan ini, maka pembelajaran materi kecepatan sudut disarankan untuk dilakukan dengan menekankan pada pemahaman konsep kecepatan sudut dan perbedaan antara rumus kecepatan sudut dengan rumus kecepatan linier. The errors of the first-semester students in solving the angular velocity problem in trigonometry courseAbstractThis qualitative research that used case study approach aimed to describe the errors of the first semester students in solving the angular velocity problem. Seven students of the mathematics education study program at a university in Malang City involved as the research subject. The data collected in this study consisted of the subject’s work on the midterm test which contains angular velocity problems and transcripts of interviews with the subject. Data analysis of the subject’s work was carried out by classifying based on the types of errors. Meanwhile, the transcript analysis of the interview results was carried out by coding the words that indicated the cause of the subject’s error. The results showed that the errors of the first semester students in solving the angular velocity problem consisted of conceptual and principle errors. The conceptual errors were caused by a lack of understanding of angular velocity concept and the factor causing principle errors was the misunderstanding that the linear velocity formula is the same as the angular velocity formula. Therefore, to avoid this error, the learning of angular velocity is suggested to emphasize the understanding of the concept of angular velocity and the difference between the angular and linear velocity formula.

Abstract

The bacterium Vibrio cholerae is the cause of cholera. Cholera is spread through the feces of an infected individual in a population. From a mathematical point of view, this problem can be brought into a mathematical model in the form of Susceptible-Infected-Recovered (SIR), which considers the birth rate. Because outbreaks that occur easily spread if not treated immediately, it is necessary to control the susceptible individual population by vaccination. The vaccine used is Oral Vibrio cholera. For this reason, the purposes of this study were to establish a model for the spread of cholera without vaccination, analyze the stability of the model around the equili­brium point, form a model for the spread of cholera with vaccination control, and describe the simulation results of numerical model completion. Based on the analysis of the stability of the equilibrium point of the model, it indicates that if the contact rate is smaller than the sum of the birth rate and the recovery rate, cholera will disappear over time. If the contact rate is grea­ter than the sum of the birth rate and the recovery rate, then cholera is still present, or in other words, the disease can still spread. Because the spread is endemic, optimal control of the popu­lation of susceptible individuals is needed, in this case, control by vaccination, so that the popu­lation of susceptible individuals becomes minimum and the population of recovered indivi­duals increases.

This is design research which consists of three stages, namely experimental preparation, teaching experiment, and retrospective analysis. The research subjects were students of class VIII in a junior high school in Aceh Besar, Indonesia. The trial of Hypothetical Learning Trajectory (HLT) for cycle 1 that was performed offline involved three students and the trial of Hypothetical Learning Trajectory (HLT) for cycle 2 that was performed online involved 10 students. The instruments for data collection were student activity sheet (worksheet), observation sheet, interview protocol, field note, and learning video recording. The research produced a pyramid learning trajectory obtained from revising HLT by presenting more pyramid models in everyday life, drawing more pyramid nets, recognizing patterns in determining the number of face diagonal, and displaying 3D animations through GeoGebra. The pyramid learning trajectory started from drawing a pyramid, drawing the net of a pyramid, finding formulas related to the relationship between pyramid elements, finding the formula for the surface area of a pyramid, and finding the formula for the volume of a pyramid. The developed learning trajectory, theoretically, could foster students’ spatial ability through realistic mathematics education on the learning material about pyramid.

Abstract

Transportasi intra-hospital merupakan transportasi dalam area suatu rumah sakit, termasuk di dalamnya adalah transportasi pasien. Transportasi pasien dalam area rumah sakit dilakukan oleh transporter pasien yang merupakan staf non-medis rumah sakit. Tugas transporter pasien adalah menjemput dan mengantarkan pasien yang membutuhkan bantuan untuk berpindah lokasi dalam area rumah sakit dikarenakan kondisinya yang tidak dapat berpindah sendiri untuk menjalani perawatan yang telah terjadwal. Penjadwalan transporter pasien harus mempertim­bangkan beberapa hal yang di antaranya tidak boleh terlambat dalam mengantarkan pasien se­suai jadwal perawatan, adanya time windows untuk masing-masing lokasi penjemputan dan pengantaran, masing-masing pasien memiliki batas maksimum untuk berada di perjalanan, ter­batasnya jumlah transporter pasien serta batasan jam kerja transporter pasien. Permasalahan ini akan dimodelkan dengan pendekatan model Dial-A-Ride Problem (DARP). Fungsi tujuan mo­del ini adalah meminimalkan total waktu tempuh transporter pasien dan jumlah transporter pasien yang ditugaskan. Model diterapkan pada  suatu kasus di salah satu  rumah sakit di Jakarta. Berdasarkan hasil penyelesaian diperoleh hasil penjadwalan yang optimum menggunakan pro­gram LINGO 11.0.Model of patient transporter scheduling problem with Dial-A-Ride Problem (DARP) approachIntra-hospital transportation is transportation within the area of a hospital including the patient transportation. Patient transportation within the hospital area is carried out by patient trans­porters who are non-medical staff of the hospital. The task of the patient transporter is to pick up and deliver patients who need help to switch locations within the hospital area due to their con­dition that cannot move on their own to undergo scheduled treatment. Scheduling a patient transporter should consider several things including not being late in delivering patients accor­ding to the treatment schedule, the existence of time windows for each pickup and drop off location, each patient has a maximum limit on the journey, limited number of patients transpor­ters, and limits on patient transporter working hours. This issue will be modeled with Dial-A-Ride Problem (DARP) model approach. The purpose function of this model is to minimize the total travel time of the patient transporter and the number of patient transporters assigned. The model is applied to a case in one of the hospitals in Jakarta, Indonesia. The results showed op­timum scheduling using LINGO 11.0 program.

Abstract

This descriptive qualitative study aimed at describing students’ thinking process in solving arithmetic sequence problems based on students’ adversity quotient (AQ). Two students who have camper type of AQ and two students who have transition from camper to climber type of AQ were involved in this study. We employed a questionnaire to identify the type of AQ that students have, a test to collect data on students’ problem-solving process, and an interview guideline to clarify students’ thinking process in problem-solving. The collected data were analyzed by following a process consisting of data reduction, data presentation, and drawing conclusions or verification. The results revealed that the students who have camper type of AQ demonstrated an assimilation thinking process on the stage of understanding problem and devising a problem-solving plan, an accommodation-assimilation thinking process on the stage of devising a problem-solving plan, and an accommodation thinking process on the stage of looking back. As for students who have transition from camper to climber type of AQ, they have similar thinking process with that of the students who have camper type of AQ on the stage of understanding problem, devising a problem-solving plan, and executing the problem-solving plan, but these students demonstrated different thinking process on the stage of looking back. In the stage of looking back, the students who have transition from camper to climber type of AQ presented an accommodation-assimilation thinking process that can be found from their responses to the test and interview.
