Analisis Fisiko-Kimiawi Tepung Sukun Hasil Fermentasi Sebagai Produk Fortifikasi Flavor Hartati .
Chemica: Jurnal Ilmiah Kimia dan Pendidikan Kimia Vol 11, No 2 (2010)
Publisher : Jurusan Kimia FMIPA UNM

ABSTRAK Penelitian ini bertujuan mengetahui kadar gula dan kadar air tepung sukun hasil fermentasi dan mengetahui daya tahan penyimpanan cake berbahan tepung sukun terfermentasi. Penelitian ini terdiri dari tiga perlakuan yaitu perlakuan A1 (Cake berbahan tepung terigu), A2 (cake berbahan tepung sukun) dan A3 (cake berbahan tepung sukun terfermentasi). Analisis kadar gula digunakan metode Anthrone sedangkan analisis kadar air dengan metode oven. Hasil penelitian diperoleh kadar gula dari cake bahan tepung sukun terfermentasi pada perlakuan A3 lebih tinggi yaitu 0,948 % dibandingkan dengan cake bahan tepung terigu (A1) yaitu 0,480%. Kadar air dari cake bahan tepung sukun terfermentasi pada perlakuan A3 paling rendah yaitu 142,3% dibandingkan dengan A1 yaitu 904%. Cake bahan tepung sukun terfermentasi kurang tahan lama dalam penyimpanan dibandingkan dengan cake bahan tepung terigu (A1) dan bahan tepung sukun (A2). Tepung sukun terfermentasi lebih tahan lama dibandingkan tepung sukun dan tepung terigu. Kata Kunci: Fisiko-kimiawi, Tepung Sukun fermentasi, fortifikasi ABSTRACT The aim of this research is to know the sugar and water concentration of the bread powder from fermentation and the storage resistance of the cake that made from the fermentation bread tree powder. This research consist of 3 treatments: A1 (cake made from wheat flour), A2 ( cake made from the bread tree powder) and A3 (cake made from the fermentation bread tree powder). Sugar concentration analyze using Anthrone method and for water concentration analyze using oven method.The result on sugar concentration analysis, that the highest treatment shown by A3 equal to 0,948 % between to cake made from wheat flour (A1) about 0,480 %. The smallest water concentration shown by A3 (cake made from the fermentation bread tree powder) about 142,3 % between from treatment A1 about 904 %. Treatment A1 and A2 more storage resistance than A3 (cake made from the fermentation bread tree powder). fermentated bread tree powder more storage resistance than A1 and A2. Key Word: fermented the bread tree powder, fortification

Pengaruh Strategi PBL Terhadap Keterampilan Metakognisi dan Respon Mahasiswa Muhammad Danial .

Publisher : Jurusan Kimia FMIPA UNM

ABSTRAK Penelitian ini bertujuan untuk menjelaskan pengaruh strategi PBL terhadap keterampilan metakognisi dan respon mahasiswa atas penerapan strategi pembelajaran tersebut. Rancangan penelitian yang digunakan adalah “Pretest-Postest Nonequivalent Control Group Design”. Hasil penelitian menunjukkan bahwa mahasiswa yang dibelajarkan melalui strategi Problem-based Learning (PBL) memiliki peningkatan skor rata-rata keterampilan metakognisi sebesar 39,75 lebih tinggi dari pada mahasiswa yang dibelajarkan melalui strategi kooperatif konvensional yaitu sebesar 30,30. Berdasarkan hasil uji ANAKOVA diperoleh bahwa terdapat perbedaan sangat signifikan keterampilan metakognisi mahasiswa yang dibelajarkan melalui strategi PBL dengan mahasiswa yang dibelajarkan melalui strategi konvensional. Selain itu, penerapan strategi PBL juga direspon secara positif oleh mahasiswa yang dibelajarkan dengan menggunakan strategi tersebut. Kata kunci: strategi PBL, keterampilan metakognisi ABSTRACT This study aims to explain the effect of PBL strategy to students metacognitive skill and respon to the applied PBL strategy. The research design that used is “Pretest-Posttest Nonequivalent Control Group Design”. This study indicates that students that learned with PBL strategy have scores of metacognitive skill from pretest to posttest 39.75 higher than students that learned with conventional strategy, 30.30. Based on the ANACOVA test showed that there were significance differences of students’ metacognition ability between the students who were thought through PBL strategy and the students who were thought through conventional strategy. Beside that, apply PBL strategy also responed positively by students that learned with the strategy applies. Keywords: PBL strategy, metacognitive skill

Peningkatan Aktivitas dan Hasil Belajar Kimia Melalui Kombinasi Metode Diskusi Dan Latihan Berstruktur (telaah pada pokok bahasan tata nama dan persamaan reaksi kimia) Murniaty .

Publisher : Jurusan Kimia FMIPA UNM

ABSTRAK Telah dilakukan penelitian untuk meningkatkan aktivitas dan hasil belajar siswa melalui pendekatan diskusi dan latihan berstruktur. Penelitian ini merupakan penelitian tindakan kelas yang pelaksanaan meliputi tiga siklus. Obyek penelitian ini adalah siswa kelas X-B SMA Negeri 1 Barru semester ganjil tahun ajaran 2010/2011 yang berjumlah 40 orang siswa. Pengumpulan dan analisis data dilakukan secara kualitatif berupa hasil observasi dan angket, sedang secara kuantitatif berupa skor tes hasil belajar. Hasil penelitian diperoleh ; (1). kemampuan siswa kelas X SMA Negeri 1 Barru dalam penguasaan kimia, khususnya materi persamaan Tata nama dan persamaan reaksi kimia cukup baik, (2). pendekatan pembelajaran menggunakan kombinasi ”metode diskusi dan latihan berstruktur” sangat signifikan meningkatkan hasil belajar siswa, khususnya pelajaran Kimia. Namun demikian masih diperlukan berbagai variasi pendekatan yang lebih efektif untuk diterapkan demi peningkatan hasil belajar siswa. Kata kunci : metode diskusi, latihan berstruktur ABSTRACT Research has been done to improve the activity and student learning outcomes through a structured approach to discussions and exercises. This research is the implementation of a class action covering three cycles. Object of this study were senior high school students in grade 1 XB Barru odd semester of the academic year 2010/2011 which amounted to 40 students. Data collection and analysis carried out qualitative observations and questionnaires, were quantitatively studied the results of the test scores. The results obtained: (1). ability of class X in a SMA Negeri 1 Barru mastery of chemistry, especially the material equations and nomenclature of chemical reaction equation is quite good, (2). learning approach using a combination of "structured training methods and the discussion was" very significantly improve student learning outcomes, particularly the lessons of Chemistry. However, still required a variety of more effective approaches to be applied in order to improve student learning achivement. Keyword: learning, discussion method, practice to structure
