Abstract

Abstract The implementation of the 2013 revised curriculum requires students to be able to think critically. The field of mathematics, especially logarithmic material, contains many characteristics, so it requires the ability to think critically to solve the problem. Meanwhile, the ability to think critically is influenced by students' cognitive styles, such as the visualizer and verbalizer cognitive styles. So it is necessary to do research to analyze students' critical thinking skills in solving logarithmic problems viewed from the two cognitive styles. This qualitative descriptive research is used by the teacher as a learning design or strategy so that it can improve students' critical thinking skills according to their cognitive style. The subjects are class X students of SMAN 1 Kamal with visualizer and verbalizer cognitive style. The data analysis technique begins with the VVQ cognitive style test (Visualizer-Verbalizer Questionnaire), problem-solving tests, and interview tests. The results obtained by the visualizer subject in TPM 1 were 14 (good critical thinking category), and TPM 2 scored 12 (adequate critical thinking category). While the verbalizer subject in TPM 1 has a score of 13 (adequate critical thinking category), and TPM 2 is 9 (adequate critical thinking category). Based on the research results, it can be concluded that the critical thinking ability of the visualizer subject dominates compared to the verbalizer subject, because it is able to detect inconsistencies and solve problems systematically. Keywords: Thinking, Critical, Visualizer, Verbalizer, Logarithm. Abstrak Penerapan kurikulum 2013 revisi menuntut siswa untuk mampu berpikir kritis. Bidang matematika khususnya materi logaritma memuat banyak sifat, sehingga diperlukan kemampuan berpikir kritis untuk memecahkan masalahnya. Sementara, kemampuan berpikir kritis dipengaruhi oleh gaya kognitif siswa, seperti gaya kognitif visualizer dan verbalizer. Sehingga perlu dilakukan penelitian untuk analisis kemapuan berpikir kritis siswa dalam menyelesaikan masalah logaritma ditinjau dari kedua gaya kognitif tersebut. Penelitian deskriptif kualitatif ini digunakan guru sebagai rancangan ataupun strategi pembelajaran sedemikian sehingga dapat meningkatkan kemampuan berpikir kritis siswa sesuai gaya kognitifnya. Subjek merupakan siswa kelas X SMAN 1 Kamal dengan gaya kognitif visualizer dan verbalizer. Teknik Analisis data diawali dengan tes gaya kognitif VVQ (Visualizer-Verbalizer Quistionnairre), tes penyelesaian masalah, dan tes wawancara. Hasil yang diperoleh subjek visualizer dalam TPM 1 adalah 14 (Kategori berpikir kritis baik), dan TPM 2 bernilai 12 (Kategori berpikir kritis cukup). Sedangkan subjek verbalizer dalam TPM 1 memiliki nilai 13 (Kategori berpikir kritis cukup), dan TPM 2 bernilai 9 (Kategori berpikir kritis cukup). Hasil penelitian menyimpulkan bahwa kemampuan berpikir kritis subjek visualizer mendominasi dibanding subjek verbalizer, dikarenakan mampu mendeteksi inkonsistensi dan menyelesaikan permasalahan secara sistematis. Kata Kunci: Berpikir, Kritis, Visualizer, Verbalizer, Logaritma.

Abstract

Abstract The results of the achievements of Indonesian students in the 2018 Program for International Student Assessment (PISA) show that Indonesian students' mathematical abilities are still below average. One of the reasons for the low PISA Indonesia 2018 results is that students are not used to non-routine questions, students are more interested in solving questions according to the material but do not understand contextual questions. In addition, many students think that mathematics is one of the solutions to this problem is learning that is difficult and boring. Based on these problems, an interesting and contextual mathematics learning approach is needed according to the mandate of the 2013 curriculum. One of them is by learning mathematics based on local culture or better known as ethnomatematics. This research is a descriptive study with an ethnographic approach to geometry material which is one of the contents of PISA. The purpose of this study is to explore the concepts of geometric transformation in the decoration of buildings of a typical cultural heritage of Yogyakarta. The results showed that the variety of decorations in Yogyakarta-specific cultural heritage buildings contained geometric transformation concepts including translation (shift), reflection (reflection), rotation (rotation), and dilation (multiplication). Keywords: ethnomatematics, decoration, geometric transformation. Abstrak Hasil prestasi siswa Indonesia pada Programme for International Student Assesment (PISA) 2018 menunjukkan kemampuan matematika siswa indonesia masih di bawah rata-rata. Salah satu alasan rendahnya hasil PISA Indonesia 2018 adalah siswa tidak terbiasa dengan soal non-rutin, siswa lebih tertarik menyelesaikan soal sesuai materi tetapi kurang memahami soal yang bersifat kontekstual. Selain itu banyak siswa yang beranggapan bahwa matematika adalah Salah satu solusi dari permasalahan ini adalah pembelajaran yang sulit dan membosankan. Berdasarkan permasalahan tersebut, dibutuhkan pendekatan pembelajaran matematika yang menarik dan kontekstual sesuai amanat kurikulum 2013. Salah satunya dengan pembelajaran matematika berbasis budaya lokal atau lebih dikenal dengat etnomatematika. Penelitian ini merupakan penelitian deskriptif dengan pendekatan etnografi pada materi geometri yang menjadi salah satu konten dari PISA.Tujuan dari penelitian ini untuk melakukan eksplorasi konsep-konsep transformasi geometri pada ragam hias bangunan cagar budaya khas Yogyakarta. Hasil Penelitian menunjukkan bahwa ragam hiasan pada bangunan cagar budaya khas Yogyakarta mengandung konsep-konsep transformasi geometri yang meliputi translasi (pergeseran), refleksi (pencerminan), rotasi (perputaran), dan dilatasi (perkalian). Kata Kunci: etnomatematika, ragam hias, transformasi geometri

Abstract

Abstract This study aims to describe the process of asking students questions in solving problems with no specified universal set given on rectangular material. The process of asking questions posed by students is adjusted to the problem-solving steps according to Polya, namely understanding the problem, making plans, implementing plans, and checking again. The research method used is qualitative with descriptive type. The instruments used in this study were tests and interviews. The test was given to all grade IX students of MTs Ma'arif Jumo who live in Pondok Pesantren Al-Falah Kalibarang. After the first stage of the test, three research subjects were selected. Selected subjects are determined based on the answers given by students with at least two possible answers accompanied by reasons and supporting evidence. Selected subjects were given a second test and then an interview was conducted. Based on the results of data analysis, the process for asking questions to each student varies depending on the answers given. Subjects Type 1 and Subject 3 go through three stages of asking questions, namely enabling action, thinking critically, and closing a session. Subject Type 2 went through four stages of asking questions, namely enabling action, thinking critically, addressing issues, and closing a session. The process that differentiates questioning between Type 1 and Type 3 subjects is that Type 1 does not try the other broad possibilities of the rectangle. Subject Type 1 is confused so there is no question. Unlike the Type 1 subject, the Type 3 subject has tried all the other possible areas of the rectangle, so that the Type 3 subject is sure the problem is resolved so that there are no questions at the addressing issues stage. Keywords: The Process Of Asking Questions, Problems With No Specified Universal Set Given, rectangular Abstrak Tujuan penelitian ini yaitu mendeskripsikan proses pengajuan pertanyaan siswa dalam menyelesaikan problems with no specified universal set given pada materi segi empat. Proses pengajuan pertanyaan yang diajukan oleh siswa disesuaikan dengan langkah pemecahan masalah menurut Polya, yaitu memahami masalah, membuat rencana, melaksanakan rencana, dan memeriksa kembali. Metode penelitian yang digunakan yaitu kualitatif dengan jenis deskriptif. Instrumen yang digunakan dalam penelitian ini adalah tes dan wawancara. Tes diberikan kepada seluruh siswa kelas IX MTs Ma’arif Jumo yang tinggal di Pondok Pesantren Al-Falah Kalibarang. Setelah dilakukan tes tahap pertama terpilih tiga subjek penelitian. Subjek terpilih ditentukan berdasarkan jawaban yang diberikan oleh siswa dengan minimal dua jawaban kemungkinan disertai dengan alasan dan bukti yang mendukung. Subjek terpilih diberikan tes tahap dua dan selanjutnya dilakukan wawancara. Berdasarkan hasil analisis data proses pengajuan pertanyaan pada setiap siswa berbeda-beda tergantung jawaban yang diberikan. Subjek Jenis 1 dan Subjek 3 melalui tiga tahapan pengajuan pertanyaan yaitu enabling action, thinking critically dan closing a session. Subjek Jenis 2 melalui empat tahapan pengajuan pertanyaan yaitu enabling action, thinking critically, addressing issues, dan closing a session. Proses yang membedakan pengajuan pertanyaan antara subjek Jenis 1 dan Jenis 3 adalah Jenis 1 tidak mencoba kemungkinan-kemungkinan luas segi empat yang lain. Subjek Jenis 1 bingung sehingga tidak ada pertanyaan. Berbeda dengan subjek Jenis 1, subjek Jenis 3 telah mencoba semua kemungkinan luas segi empat yang lain, sehingga subjek Jenis 3 telah yakin dengan permasalahan yang diatasi sehingga tidak ada pertanyaan pada tahap addressing issues. Kata Kunci: Proses Pengajuan Pertanyaan, Problems With No Specified Universal Set Given, Segi empat

Abstract

AbstractOver the past five years, the incidence of fires at the Situbondo Regency has increased. For the following years, the Situbondo district government plans to add new fire stations to reach areas that have not been or are difficult to reach by fire and rescue unit personnel. In the construction plan for a new fire station, we need to construct a model that can determine where and how many new fire stations. This research aims to determine the optimal location and number of fire stations taking into account dispatch time, construction cost, and fire toll in Situbondo district using the set covering problem model. Furthermore, we find the solution of the model by using the branch and bound method compiled from the GAMS optimization software. The optimal solution of the set covering problem model which minimizes the opening cost of the fire station as the objective function is, and each equal to 1 with Z equal to 6. Based on the result, the optimal location of the fire station in Situbondo district is in the sub-districts of Banyuglugur, Mlandingan, Bungatan, Panji, Kapongan, and Arjasa, each with a type C station. Currently, Situbondo district fire stations are located in Panji (type A), Asembagus (type C), and Besuki (type C) sub-districts. The costs incurred for the construction of the three fire stations are 7. The total cost of new fire station construction in the optimization model is less than the cost issued at this time. Keywords: set covering problem, branch and bound, fire station location, GAMS. AbstrakSelama lima tahun terakhir, kejadian kebakaran di Kabupaten Situbondo meningkat. Beberapa tahun kedepan, Pemerintah Kabupaten Situbondo berencana akan menambah pos baru untuk menjangkau daerah-daerah yang selama ini belum atau sulit dijangkau oleh personil UPT Pemadam Kebakaran dan Penyelamatan. Dalam rencana pembangunan pos pemadam kebakaran baru dibutuhkan metode yang tepat untuk menentukan dimana dan jumlah lokasi pos pemadam kebakaran baru yang strategis. Penelitian ini bertujuan untuk menentukan lokasi dan jumlah pos pemadam kebakaran yang optimal dengan mempertimbangkan waktu tempuh, biaya pembangunan, dan rekam jejak terjadinya kebakaran di Kabupaten Situbondo menggunakan model set-covering problem. Selanjutnya, model tersebut diselesaikan menggunakan metode branch and bound dengan menggunakan software optimasi GAMS. Penyelesaian model optimasi Set Covering Problem yang meminimalkan fungsi objektif biaya pembukaan pos pemadam kebakaran adalah , dan  masing-masing sama dengan 1 dengan nilai Z adalah 6. Berdasarkan hasil tersebut lokasi pos pemadam kebakaran yang optimal di Kabupaten Situbondo adalah di Kecamatan Banyuglugur, Mlandingan, Bungatan, Panji, Kapongan, dan Arjasa yang masing-masing dengan tipe pos pemadam kebakaran C. Saat ini lokasi pos pemadam kebakaran yang dimiliki oleh UPT Pemadam Kebakaran dan Penyelamatan Kabupaten Situbondo terletak di 3 lokasi, yaitu Kecamatan Panji (tipe A), Kecamatan Asembagus (tipe C), dan Kecamatan Besuki (tipe C), maka biaya yang dikeluarkan untuk pembangunan ketiga pos pemadam kebakaran tersebut adalah 7. Total biaya pembangunan pos pemadam kebakaran baru pada model optimasi lebih kecil daripada biaya yang dikeluarkan saat ini. Kata Kunci: set covering problem, branch and bound, lokasi pos pemadam kebakaran, GAMS.

Abstract

Abstract This study aims to analyze how much students have achieved independence in learning. Self-Regulated Learning includes all things student learning independently without the help of others, student learning motivation, or things that affect student independence in learning, especially in learning mathematics. This analytical study will be continued as an effort to increase self-regulated learning. The scope of self-regulated learning is very broad, but it can be analyzed by several methods, one of which is by doing quantitative descriptive with data collection techniques in the form of questionnaires or questionnaires on research objects taken from several populations. In this study, respondents were drawn from a population of students of class VIII D at SMPN 2 Lemahabang Karawang with a total of 25 respondents. The study was conducted with indicators of learning independence as measured by the respondent's ability to respond to the mathematics learning independence scale with 18 statements that can be responded to by respondents with a 5-point Likert scale. After analyzing according to the indicators of learning independence, the data obtained was processed further to determine the percentage of student learning independence phases. From the results of the analysis and evidence of the value of self-regulated learning in material learning, the results for the planning phase (27.47%), the implementation phase (33.02%), and the evaluation phase (24.80%) were obtained. And overall obtained an average of 28.97%. This shows that the application of self-regulated learning in class VIII D students of SMPN 2 Lemahabang Karawang is still very low, so there is a need for efforts to increase self-regulated learning to achieve the desired learning objectives and make students successful in studying. Keywords: Analysis, Likert scale, Self-Regulated Learning Abstrak Tujuan dari penelitian ini yakni menganalisis seberapa besar siswa telah mencapai kemandiriannya dalam belajar. Kemandirian belajar siswa mencakup segala hal belajar siswa secara mandiri tanpa bantuan orang lain, motivasi belajar siswa ataupun hal yang mempengaruhi kemandirian siswa dalam belajar, khususnya dalam pembelajaran matematika. Kajian analisis ini akan dilanjutkan sebagai upaya peningkatan self-regulated learning. Cakupan dari self-regulated learning sangatlah luas, namun dapat dianalisis dengan beberapa metode, salah satunya adalah dengan melakukan deskriptif kuantitatif melalui teknik pengumpulan data berupa angket atau kuisioner pada objek penelitian yang diambil dari populasi. Pada penelitian ini, responden diambil dari populasi siswa kelas VIIID pada SMPN 2 Lemahabang Karawang dengan jumlah 25 responden. Penelitian dilakukan dengan indikator kemandirian belajar yang diukur dari kemampuan responden dalam menyikapi skala kemandirian belajar matematika dengan 18 pernyataan yang dapat ditanggapi oleh responden dengan skala Likert yang memiliki 5 poin. Setelah melakukan analisis sesuai indikator kemandirian belajar, data yang diperoleh diolah secara lanjut untuk mengetahui persentase fase-fase kemandirian belajar siswa. Dari hasil analisis dan pembuktian nilai self-regulated learning pada pembelajaran matematika didapatkan hasil untuk fase perencanaan (27,47%), fase pelaksanaan (33,02%) dan fase evaluasi (24,80%). Dan secara keseluruhan diperoleh rata-rata sebesar 28,97%. Hal tersebut menunjukan bahwa penerapan self-regulated learning pada siswa kelas VIIID SMPN 2 Lemahabang Karawang masih sangat rendah, sehingga perlu adanya upaya dalam meningkatkan self-regulated learning agar tercapai tujuan belajar yang diinginkan serta menjadikan siswa sukses dalam belajarnya.
