AbstractTechnological Pedagogical and Content Knowledge (TPACK) is the insight to integrate technology into teaching in a particular material. Chemistry teachers are required to master the technology in teaching chemistry so that they become professional teachers. This study aims to determine the ability of TPACK towards the Internship student in delivering learning materials in the internship school. This research applied a descriptive study by using a quantitative approach. Samples of study are three students of Chemistry Education program taking internship program in SMAN 4 Banda Aceh (by being coded A1) and Syiah Kuala University High School Laboratory (by being coded B1 and B2). Data were collected by conducting through observation when internship students were in the classroom. Observations were carried out twice for each internship student. Observer in this study consisted of two people namely researchers and advisor of internship students. The results showed that mastery of learning material of internship students with A1, B1, and B2 code varied that the lowest score was 49% as sufficient category score and the highest score was 91% that was indicated as very good. The lowest score in the pedagogical knowledge of internship students was 54% as sufficient category while the highest score of 93% included as a very good category. The ability of technological knowledge reached at least 56%, as the highest category reached 81% that was categorized as very good. The ability of Content Knowledge for the lowest percentage was 50% as sufficient category, but the highest score was 80% as good category.

AbstrakTelah dilakukan penelitian penyerapan ion logam Pb(II) menggunakan serbuk gergaji kayu pinus (Pinus mercusii). Penelitian ini bertujuan untuk mengetahui daya serap serbuk gergaji kayu pinus (Pinus mercusii) terhadap ion logam Pb(II). Populasi serbuk gergaji kayu pinus yang digunakan sebagai adsorben ion logam Pb(II) ini diambil dari pegunungan Bur Gajah Kecamatan Blangpegayon Kabupaten Gayo Lues dengan sampel sebanyak 200 gram. Studi penyerapan dilakukan dengan memvariasikan variabel pH, kecepatan pengadukan, pengaruh temperatur dan konsentrasi awal ion logam Pb(II). Konsentrasi sisa penyerapan ion logam Pb(II) diukur menggunakan spektrofotometri serapan atom (SSA). Kapasitas penyerapan serbuk gergaji dihitung menggunakan dua model isoterm yaitu isoterm Langmuir dan Freundlich. Setelah kondisi optimum didapatkan serbuk gergaji kayu pinus diaktivasi secara kimia menggunakan larutan NaOH 0.1 N, sebagai kontrol digunakan adsorben tanpa aktivasi. Kondisi optimum hasil penelitian serbuk gergaji kayu pinus dengan ukuran ayakan 150 mesh, waktu kontak 30 menit dan massa serbuk gergaji kayu 1 gram dapat menyerap ion logam Pb(II) pada kondisi pH 5, kecepatan pengadukan 100 rpm, dan suhu 75C. Berdasarkan hasil perhitungan kapasitas penyerapan berdasarkan model isoterm Langmuir dan Freundlich berturut-turut yaitu 7,7041 mg/g dan 0,8635 mg/g, serta perbandingan efisiensi penyerapan secara aktivasi dan tanpa aktivasi yaitu sebesar 99,84% dan 85,47%.Kata kunci: Daya serap, serbuk gergaji, pinus (Pinus mercusii), ion logam Pb(II), AASAbstractThe research has been conducted about ion absorption of Pb (II) by using sawdust pine (Pinus mercusii). This study aims to determine the absorption of sawdust pine (Pinus mercusii) towards metal ions Pb (II). The population of pine wood sawdust that was used as adsorbent metal ions Pb (II) was taken from Bur Gajah mountain Blangpegayon district of Gayo Lues with 200 grams sample. Studies of absorptions were conducted by varying the variable of pH, the speed of stirring, the temperature effect and the initial concentration of metal ions Pb (II). The concentration of residual absorption of metal ions Pb (II) was measured by using atomic absorption spectrophotometry (AAS). The absorption capacities of sawdust were calculated by using two models namely the isotherm Langmuir isotherm and Freundlich. After being gotten the optimum condition, the pine wood sawdust was chemically activated by using 0.1 N NaOH solutions, as an adsorbent that was used without activation control. The optimum conditions of the results of sawdust pine wood with size 150 mesh, contact time of 30 minutes and a mass of sawdust 1 gram can absorb metal ions Pb (II) at pH 5, 100 rpm the speed of stirring, and a 75 C temperature. Based on the results of the absorption capacity from isotherm Langmuir and Freundlich models, it can successively be obtained namely 7.7041 mg / g and 0.8635 mg / g. then, the comparison of the efficient absorption through activation and without activation were 99.84% and 85.47%.Keywords: Absorption, sawdust, pine (Pinus mercusii), metal ions Pb (II), AAS

Penelitian ini bertujuan untuk mengetahui tingkat pemahaman siswa menggunakan three-tier multiple choice dan penyebab kesulitan siswa pada materi termokimia. Penelitian dilakukan di MAN Model Banda Aceh menggunakan rancangan penelitian deskriptif dengan pendekatan kualitatif. Subjek penelitian ini adalah siswa kelas XI MIA 5 yang berjumlah 17 siswa. Teknik pengambilan sampel pada penelitian ini adalah purposive sampling. Pengumpulan data diperoleh dengan tes three-tier multiple choice yang terdiri dari 12 soal dan wawancara. Hasil penelitian menunjukkan bahwa rata-rata persentase kemampuan siswa pada materi termokimia adalah 9,79% yang paham konsep, 24,50% tidak paham konsep, 63,72% mengalami miskonsepsi, dan 1,96% error. Berdasarkan kriteria pendeskripsian tingkat pemahaman konsep siswa, persentase yang diperoleh berada dibawah 30%-45% dengan kategori gagal. Hasil analisis data menunjukkan siswa kurang memahami pada persamaan termokimia dan konsep mol. Faktor penyebab kesulitan siswa antara lain siswa kurang mampu dalam menyimpan informasi secara luas, kurang fokus pada saat guru menjelaskan, sulit dalam memahami materi yang bersifat algoritmik, membutuhkan alat bantu untuk berhitung, dan kurangnya fasilitas laboratorium menyebabkan siswa gagal mendapatkan hasil yang akurat.Kata kunci : kesulitan, termokimia, three-tier multiple choice.AbstractThe objectives of study were to understand level of students understanding by using three-tier multiple choice and cause of students adversity in learning of thermochemistry. The study was conducted in MAN Model Banda Aceh by model of descriptive research with a qualitative approach. Subject of study was 17 students of class XI MIA 5. Then, technique of sampling was purposive sampling. Data were collected by using test of three-tier multiple choice which is consist of 12 questions and interview. The study indicated that the average percentages of students understanding were 9.79% of understand the conception, 24.50% of wrong conception, 63.72% of misconception and 1.90 of error. According to the description of level of understanding, the percentage was under of 30%-45% with a category of failure. Consequently, the analysis of data exhibited that the students have lack of understanding in learning of thermochemistry and mole concept. The students adversity was caused by lack of memorize in order to keep huge information, bad focus when the teacher teach, difficult to understand the algorithmic materials, require the counting-tools, and lack of laboratory facilities.Keyword: adversity, thermochemistry, three-tier multiple choice.
