    Abstract

    Tujuan penelitian ini adalah memperoleh profil model mental siswa pada konsep dasar laju
    reaksi. Partisipan penelitian ini adalah tujuh orang siswa kelas XII IPA di salah satu SMA
    Negeri di Kota Bandung dengan tiga kemampuan akademik yang berbeda, yaitu tinggi,
    sedang, dan rendah. Metode yang digunakan adalah kualitatif dengan analisis deskriptif
    menggunakan instrumen penelitian Tes Diagnostik Model Mental Inteview-About-Event
    (IAE). Berdasarkan hasil penelitian ditemukan bahwa siswa kemampuan sedang dan rendah
    menjawab benar sebagian setalah diberi pertanyaan probing dalam menjelaskan perubahan
    laju rerata pengurangan reaktan dan laju rerata pembentukan produk, sedangkan siswa
    kemampuan tinggi menjawab salah meskipun telah diberi pertanyaan probing. Siswa
    kemampuan tinggi, sedang dan rendah mengalami miskonsepsi dalam menjelaskan laju
    rerata pembentukan produk, bahwa laju rerata pembentukan produk meningkat karena
    jumlah partikelnya meningkat. Selain itu, ditemukan miskonsepsi dalam menghitung laju
    rerata, bahwa laju rerata diperoleh dengan cara membagi jumlah total laju reaksi setiap
    waktu dengan jumlah data laju reaksi. Kemudian, siswa kemampuan tinggi, sedang dan
    rendah tidak dapat menjawab apapun dalam menjelaskan laju sesaat meskipun sudah diberi
    pertanyaan probing. Terakhir, siswa kemampuan tinggi dan sedang menjawab benar
    dengan pertanyaan probing ketika membandingkan laju salah satu spesi untuk mencari
    spesi lainnya, tetapi tidak ada yang menjawab benar dalam menghubungkan laju reaksi,
    laju pengurangan reaktan, dan laju pembentukan produk.

    The research aims to obtain student’s mental model profile on the concept of reaction rate.
    The participants of this research were seven students of class XII IPA in a public senior
    high school in Bandung city with three different academic abilities, namely high, medium,
    and low. The method used is qualitative with descriptive analysis using the research
    instrument Diagnostic Test Model Mental Interview-About-Event (IAE). Based on the
    results of the research it was found that students with moderate and low ability answered
    partially correct after being given probing questions in explaining changes the average rate
    of disappearance of reactant and the average rate of formation of product , while high ability
    students answered incorrectly even though they had been given a probing question.
    Students with high, medium, and low abilities experience misconceptions in explaining the
    average rate of formation of product, that the average rate of formation of product increases
    as the number of particles increases. In addition, a misconception was found in calculating
    the average rate, that the average rate is obtained by dividing the total number of reaction
    rates at any time by the number of reaction rate data. Then, students of high, medium, and
    low ability cannot answer anything in explaining the instantaneous rate even though they
    have been given a probing question. Finally, high and moderate ability students answered
    correctly with probing questions when comparing the rate of one species to look for other
    species, but none of them answered correctly in relating the reaction rate, the average rate
    of disappearance of reactant, and the average rate of formation of product.
