Praktikum yang dilakukan sejauh ini memang sudah memiliki keterampilan proses sains untuk dinilai. Namun, penilaian yang dilakukan belum maksimal. Mahasiswa masih sangat bergantung pada koordinator praktikum, sehingga keterampilan proses sains yang dimiliki mahasiswa tidak berkembang. Pada hakikatnya keterampilan proses sains tersebut dapat meningkatkan hasil belajar. Penelitian ini bertujuan untuk mengetahui apakah ada korelasi antara keterampilan proses sains dengan hasil belajar mahasiswa pada praktikum sifat koligatif larutan. Metode penelitian ini adalah penelitian deskriptif kuantitatif. Penelitian ini dilaksanakan di kampus IKIP Mataram. Subjek pada penelitian ini adalah mahasiswa semester genap program studi pendidikan kimia, matematika dan biologi yang berjumlah 138 orang yang memprogramkan mata kuliah kimia dasar II Tahun Pelajaran 2013/2014. . Instrumen penelitian yang digunakan dalam pengumpulan data adalah lembar observasi keterampilan proses sains dan Lembar soal tes hasil belajar. Teknik analisa data untuk menghitung koefisen korelasi keterampilan proses sains dengan hasil belajar digunakan rumus pearson korelasi product moment. Hasil penelitian menunjukan bahwa keterampilan proses sains mahasiswa dalam praktikum sifat koligatif larutan memiliki korelasi positif dengan hasil belajar. Hal ini ditunjukkan oleh r sebesar 0,2897 menurut korelasi pearson product moment dan r 0,1676 dengan taraf signifikan 5%.

Studying hydrocarbon material requires ability in problem solving so students are able to identify, analyze, and describe abstract chemical concepts and principles into concrete. The purpose of this study was to the improving of students' hydrocarbon problem solving abilities through the SAVI learning model assisted by puzzle media. The research design used in this study was pre-experimental with a research design namely One Group Pretest-Posttest Design.The study was conducted at SMAN 7 Mataram, Jl. Adi Sucipto, Ampenan Utara, Kec. Ampenan, Mataram City, West Nusa Tenggara. The subjects of this study were students of class XI Science. The research instrument include syllabus, lesson plans, worksheets, and multiple choice test items. Data were analyzed using the N-Gain test to find out the increased ability to solve hydrocarbon problems. The results showed that the level of N-Gain was in the range of 0.33 with a moderate category which meant an increase in students' problem solving abilities after using the SAVI model assisted by puzzle media. Thus, it can be concluded that students' problem solving abilities can be improved through the application of SAVI learning models assisted by puzzle media.

Acid-base is one of topics considered difficult by students. This concept is broad, varied. Despite it is very closely related to everyday life, its application was still lacking. The development of teaching materials in the form of a module was deemed to be a solution to this problem. The aim of this research was to develop CTL module with green chemistry orientation in acid-base subject material to improve science literacy of students. This study was developed ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The developed product was validated by three experts, a practitioner and ten high school students. Data were analyzed using percentage formula. Qualitative data in the form of comments and suggestions from validator were used as consideration to revise the developed module.Tthe effectivity of the module was assessed using N-gain test. Based on validation results, we obtained average of 86,5%, 97%, 88%, and 94,58%. Effectivity evaluation using N-gain test shows an average score of 0,5 with moderate category. Result of student attitudes towards science data has an average score of 74% with good qualifications. It was concluded that developed module prototype is effective for acid-base topic, and most likely for other topics in learning process and growing student science literacy.

Pemanfaatan Limbah Kulit Nanas (Ananas Comocus) Sebagai Sumber Asam Oksalat Untuk Meningkatkan Efektivitas Fotoreduksi Ion Cu(Ii) Terkatalisis Tio2 Husnul Hatimah; Suryati Suryati

Publisher : Universitas Pendidikan Mandalika Mataram

Dalam penelitian ini telah dilakukan kajian pengaruh penambahan fotokatalis TiO2 dan Asam oksalat yang bersumber dari kulit nanas pada pH dan konsentrasi yang bervariasi, terhadap efektivitas fotoreduksi ion Cu(II) yang terkatalisis oleh TiO2. Proses fotoreduksi dilakukan dengan cara menyinari campuran yang terdiri dari larutan ion Cu(II) dan serbuk fotokatalis TiO2 tanpa maupun dengan adanya Asam oksalat dalam reaktor tertutup yang dilengkapi dengan lampu UV disertai pengadukan. Kondisi proses fotoreduksi adalah 50 mL larutan ion Cu(II) 10 ppm (0.157 mmol/L) dan Asam oksalat dengan konsentrasi yang bervariasi, dan TiO2 seberat 20 mg, dengan waktu reaksi selama 24 jam. Hasil fotoreduksi ditentukan berdasarkan selisih konsentrasi ion Cu(II) awal dengan konsentrasi ion Cu(II) sisa dalam larutan setelah proses fotoreduksi yang ditentukan dengan metode Spektrofotometri Serapan Atom (AAS).Hasil penelitian menunjukkan bahwa penambahan TiO2 dapat meningkatkan efektivitas fotoreduksi ion Cu(II) dari 9,03% menjadi 43,22%, yang diawali dengan proses adsorpsi. Adanya asam oksalat pada kulit nanas dapat meningkatkan fotoreduksi ion Cu(II) yang relatif tinggi karena asam oksalat dapat mencegah rekombinasi elektron dengan radikal OH, sehingga proses fotoreduksi Cu(II) dapat berjalan dengan optimal karena jumlah elektron yang tersedia relatif banyak. Pada pH yang bervariasi penambahan asam oksalat pada kulit nanas memberikan trend fotoreduksi ion Cu(II) yang sama dengan trend fotoreduksi ion Cu(II) tanpa adanya asam oksalat pada kulit nanas. Trend tersebut menunjukkan bahwa kenaikan pH 1 sampai 7 dapat meningkatkan fotoreduksi ion Cu(II), dan semua ion Cu(II) hilang dari larutan pada pH lebih tinggi dari 8 karena terbentuknya endapan Cu(OH)2. Fenomena ini berhubungan dengan spesiasi ion Cu(II), asam oksalat pada kulit nanas, dan permukaan fotokatalis TiO2

Laju Reaksi merupakan salah satu materi yang dianggap sulit oleh siswa. Hal tersebut disebabkan oleh beberapa faktor yaitu: 1) materi laju reaksi yang dipelajari tergolong pada level makroskopik, mikroskopik dan simbolik 2) metode pembelajaran yang kurang bervariasi menjadi salah satu penyebab rendahnya hasil belajar siswa pada mata pelajaran kimia. Salah satu alternatif untuk mengatasi hal tersebutditerapkanpendekatan Inquiry Based Learning.Penerapan pendekatan inkuiri based learning memungkinkan siswa terlibat secara aktif menggunakan proses mentalnya untuk menemukan beberapa konsep dan prinsip materi laju reaksi yang sedang dipelajari. Tujuandaripenelitianini adalahuntukmengetahuiprosespenerapan pendekatan inkuiri based learningdan pengaruhnya terhadap hasilbelajar siswa kelas XI SMKN 3 MataramTahun Pelajaran 2012/2013 pada materi laju reaksi.Populasidalampenelitianini terdiridariduakelasdenganjumlah55 siswa.Pengambilansampeldilakukandengan teknik cluster random sampling.

This study is aimed in developing the thermochemical learning tools based on guided inquiry that can be used in increasing the students’ science literacy. This learning tools consists of some steps that integrated to students worksheet, teacher’s book and lesson plan that dealing with 2013 curriculum. Inquiry learning is suitable to develop the students’ science literacy. This approach could help the teachers to increase students’ comprehension in lining their acknowledge with their daily life (students’ chemical science), and it could have more function for the students. So, one way to measure the students’ literacy by applying the inquiry steps as the learning achievement indicators. This research is in terms of 4-D design that consists of (1) defining, (2) designing, (3)developing and disseminating. The result was validated by two lecturers ( validators) that teaching chemical and four chemical teachers at senior high school, then it also tested in 40 SMAN 7 Mataram students through questionnaire. So, quantitative data then analyzed by percentage formula. Furthermore, qualitative data consists of some ideas, suggestions in terms of the learning tools. Based on validation result from lecturers is 86%, teachers 88%. Instruments validation literacy science result from lecturers 89%, from teachers 87%. The result from 40 students is 83%. Therefore, it can be concluded that the development learning toolsis valid to be used.
