Ini adalah penelitian deskriptif kualitatif yang menggambarkan penerapan kurikulum 2013 oleh para guru di pendidikan dasar di Pekanbaru dan kendala yang mereka hadapi. Subjek dalam penelitian ini adalah enam pendidikan dasar di Pekanbaru yang menerapkan kurikulum 2013. Subjek adalah Sekolah Dasar 36 sebagai sekolah yang memiliki kelompok belajar besar, sekolah dasar 160 sebagai sekolah yang memiliki kelompok belajar sedang, sekolah dasar 134 sebagai sekolah yang memiliki kelompok belajar kecil, SMA 1, SMA 6, dan SMA 23. Data dikumpulkan dengan mengamati pembelajaran dan mewawancarai para guru dan kepala sekolah. Data yang dianalisis menunjukkan bahwa pembelajaran berbasis kurikulum 2013 di sekolah dasar di Pekanbaru belum berjalan dengan baik. Ada beberapa kendala dalam menerapkan kurikulum 2013 dalam pendidikan dasar di Pekanbaru seperti, (1) pemahaman guru masih kurang dari kurikulum 2013; (2) belum ada perubahan \"pola pikir\" guru untuk pembelajaran kurikulum 2013; (3) sinkronisasi antara guru kelas dan guru PJOK belum terjadi; dan (4) para guru belum memahami penilaian otentik pada kurikulum 2013. \u0000  \u0000This research aims to (1) investigate the implementation of curriculum 2013 at basic education in Pekanbaru and (2) investigate the obstacles which faced by teachers at basic education in Pekanbaru implementing the curriculum 2013. This is a qualitative descriptive study which describing the implementation of curriculum 2013 by teachers at basic education in Pekanbaru and the obstacles which they faced. The subject in this study were six basic education in Pekanbaru which implementing the curriculum 2013 The subjects are the elementary School 36 as the school which having large study group, the elementary school 160 as the school which having medium study group, the elementary school 134 as the school which having small study group, yunior high school 1, yunior high school 6, and yunior high school 23. The data was collected by observing the learning and interviewing the teachers and headmaster. The analyzed data showed that the learning based of curriculum 2013 at elementary school in Pekanbaru had not gone well yet. There were some obstacles on implementing curriculum 2013 in basic education in Pekanbaru such as, (1) the understanding of teacher was still less to the curriculum 2013; (2) there is no change of “mindset” of teacher to the learning of curriculum 2013 yet; (3) the sychronization between the class teacher and the PJOK teacher is not happened yet; and (4) the teachers did not understand the authentic assessment on curriculum 2013 yet.","PeriodicalId":117967,"journal":{"name":"Talenta Conference Series: Science and Technology (ST)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131905275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seseorang yang memiliki penalaran yang baik, tentunya akan berhati-hati dalam bertindak dan memutuskan sesuatu. Materi-materi pada kalkulus merupakan materi yang ada pada tingkat sekolah menengah yang nantinya menjadi lahan mengajar mahasiswa calon guru matematika S-1. Kemampuan penalaran yang dikaji mempengaruhi pembelajaran mahasiswa kedepannya karena berlaku pada matakuliah lanjut, contohnya pada kemampuan pembuktian akan selalu digunakan pada matakuliah persamaan diferensial, struktur aljabar, analisis  vektor, analisis real, dll. Sedangkan sebagai calon guru yang nantinya mengajar pada tingkat sekolah menengah, maka kemampuan penalaran ini menjadi salah satu capaian pembelajaran matematika bagi siswa sekolah menengah, maka oleh karena itu guru yang mengajarnya haruslah memiliki kemampuan penalaran yang baik. Analisis kesalahan sangat penting untuk melakukan evaluasi dan refleksi pada struktur soal maupun pada perlakuan dalam pembelajaran dalam upaya memperbaiki kemampuan penalarannya. \u0000  \u0000Mathematical reasoning uses a logical mindset in analyzing a problem that will eventually be marked by concluding activity on the problem.

The reasoning ability studied influences student learning in the future as it applies to advanced courses, for example in the ability of proof will always be used in the course of differential equations, algebraic structure, vector analysis, real analysis, etc. While as a teacher candidate who will teach at the secondary school level, then this reasoning ability becomes one of the achievements of mathematics learning for high school students, therefore teachers who teach it must have good reasoning ability.

Methylene blue (MB), methyl orange (MO), dan phenol red (PR) mewakili pewarna golongan thiazine, azo, dan tryarilmethane masing-masing, yang ditambahkan pada kaolinite dipilih sebagai model untuk uji polutan pewarna. Alat EKR (panjang 15 cm) dilengkapi dengan arus listrik DC dengan nilai maksimum 30 V. Elektroda grafit digunakan untuk kedua anoda dan katoda dipasang untuk empat belas hari operasional. Hasilnya, hanya 40-55% pewarna yang berhasil dikeluarkan dari bagian tanah dengan menggunakan air suling. Namun, dengan penambahan beberapa elektrolit; persentase pewarna yang dikeluarkan dari tanah meningkat dari 73- 76% dan 85 - 89% untuk elektrolit natrium sulfat dan monosodium dihidrogen fosfat secara berturut-turut. Dalam konteks pengontrolan pH, ditemukan bahwa hanya 55-64% pewarna yang dikeluarkan tanpa kontrol pH. Peningkatan yang signifikan dicapai dengan mengendalikan pH sistem. Dengan mengendalikan pH di ruang katoda, didapati 23% MB, 25% MO dan 18% PR masih ada dalam sistem. Sementara dengan mengendalikan pH di ruang anoda, hampir 90% pewarna yang diuji dapat dikeluarkan dari ruang kaolinite secara efektif. Pergerakan pewarna thiazine, dari anoda ke ruang katoda dikendalikan oleh fenomena elektro-migrasi dan elektro-osmosis. Sebaliknya, pewarna azo diangkut dari katoda ke ruang anoda dengan cara yang sama. Namun, pewarna triarylmethane dikeluarkan dari bagian tanah dengan hanya melalui fenomena elektro-osmosis dari anoda ke ruang katoda. Untuk tiga jenis pewarna yang diuji, ditemukan bahwa aliran elektro-osmotik bergerak dari arah anoda ke arah katoda. \u0000  \u0000In this study, the investigation about the potency of electro-kinetic remediation technology (EKR) for the removal of organic dyes from the polluted kaolinitic soil has been conducted.
