Abstract

Research on improving student learning outcomes using concept mapping  strategy  on  hydrocarbon  material  in  class  X-1  SMAN  10 Banjarmasin has been implemented. This  research  aims  to (1) know  teacher’s and students’ activities, (2) improve learning outcomes (3) study students response to concept mapping strategy on hydrocarbon material. This research used classroom action research design, with 2 cycles. Subjects of this research were students of class X-1 in SMAN 10 Banjarmasin. Data were obtained from assessment of teacher activity, student activity, cognitive tests and questionnaire  responses. The results showed that the use of map concept strategy increased: (1) teacher activities, from good criteria in the first cycle to very good criteria in the second cycle, (2) students’ activities from good criteria in the first cycle to  very good criteria  in  the  second  cycle,  (3) students outcomes increased from   63.28% in the first cycle to 81.21% in the second cycle; (4) Learning using  map concept received a positive response from the students.

Abstract

Abstract. Utilization of chitin as a stationary phase of TLC to separate the compound components from plants had been carried out. The objective of this study was to investigate (1) the effectiveness of chitin as a stationary phase in TLC to separate the compound components of plants, and (2) composition of compounds in plant extracts that can be separated by chitin. Research method is experiment in laboratory. Sampling technique of plant extract (mahogany seed, turmeric rhizome, and pandanus leaf) using random sampling technique, while shrimp shrimp skin is shrimp waste from Indu Manis Banjarmasin factory. Data were analyzed descriptively qualitative. The results showed that chitin rendemen successfully isolated from shrimp skin was 36,44%. Chitin is effectively used as an alternative to stationary phase in TLC to separate the compound components from plant sample extracts (mahogany seeds, pandanus leaves, and turmeric rhizomes). Keywords: chitin, stationary phase of TLC, and separation of plant compound components. Abstrak. Telah dilakukan penelitian tentang pemanfaatan kitin sebagai fasa diam KLT untuk memisahkan komponen senyawa dari tumbuhan. Penelitian ini bertujuan untuk mengetahui (1) efektivitas kitin sebagai fasa diam pada KLT untuk memisahkan komponen senyawa dari tumbuhan, dan (2) komposisi senyawa dalam ekstrak tumbuhan yang mampu dipisahkan oleh kitin. Metode penelitian adalah eksperimen di laboratorium. Teknik pengambilan sampel ekstrak tumbuhan (biji mahoni, rimpang kunyit, dan daun pandan) menggunakan teknik random sampling, sedangkan kulit udang merupakan limbah kulit udang dari pabrik Indu Manis Banjarmasin. Data dianalisis secara deskriptif kualitatif. Hasil penelitian menunjukkan bahwa rendaman kitin yang berhasil diisolasi dari kulit udang sebesar 36,44%. Kitin cukup efektif digunakan sebagai alternatif fasa diam  pada KLT untuk memisahkan komponen senyawa dari ekstrak sampel tumbuhan (biji Mahoni, daun Pandan, dan rimpang Kunyit).  Kata Kunci: kitin, fase diam KLT, dan pemisahan komponen senyawa tumbuhan.

Abstract

Abstract. The ability to think creatively is one of the 21st century skills that students must possess. This ability can be improved by using a learning model that exposes students to problems directly. This research aims to increase teacher activity, student activities, creative thinking skills, and student academic achievement by implementing Creative Problem Solving (CPS) learning model in class XI IPA 2 SMA PGRI 6 Banjarmasin. The research applied classroom action research (CAR) design with 2 cycles. The subjects were 39 eleventh grade students of natural science class. The data were analyzed by percentage and descriptive quantitative technique. The results showed that the teacher's activity in the implementation of the action increased from 70.15% (good) to 85.46% (very good). Student activity in cycle I 67.27% (quite active) to 85% in cycle II (active). Students' creative thinking ability for fluency indicators was originally 59.25% to 77.42%, flexibility which was originally 37.25% to 55.03%, elaboration which was originally 39.75% to 69.75%. Classical cognitive of students with a percentage of 69.23% increased to 87.17%. Students’ affective increased from 53.35% to 70.15% in cycle II and students' psychomotor learning outcomes were originally 59.69% to 69.4% in cycle II.  Keywords: creative thinking ability, academic achievement, creative problem solving                          Abstrak. Kemampuan berpikir kreatif merupakan salah satu dari keterampilan abad 21 yang harus dimiliki siswa. Kemampuan ini dapat ditingkatkan dengan menggunakan model pembelajaran yang menghadapkan siswa pada masalah secara langsung. Penelitian ini bertujuan meningkatkan aktivitas guru, aktivitas siswa, kemampuan berpikir kreatif, dan hasil belajar siswa di kelas XI IPA 2 SMA PGRI 6 Banjarmasin dengan menerapkan model pembelajaran Creative Problem Solving (CPS). Penelitian menggunakan desain penelitian tindakan kelas (PTK) dengan 2 siklus. Subjek penelitian merupakan siswa kelas XI IPA berjumlah 39 orang. Data dianalisis menggunakan teknik persentase dan deskriptif kuantitatif Hasil penelitian menunjukkan bahwa aktivitas guru dalam pelaksanaan tindakan meningkat dari 70,15% (baik) menjadi 85,46% (sangat baik). Aktivitas siswa pada siklus I 67,27% (cukup aktif) menjadi 85% pada siklus II (aktif). Kemampuan berpikir kreatif siswa untuk indikator fluency, semula 59,25% menjadi 77,42%, flexibility yang semula 37,25 % menjadi 55,03%, elaboration yang awalnya 39,75% menjadi 69,75%. Hasil belajar kognitif siswa secara klasikal  dengan persentase 69,23% meningkat menjadi 87,17%. Hasil belajar afektif siswa meningkat dari 53,35% menjadi 70,15% pada siklus II dan hasil belajar psikomotorik siswa yang semula 59,69% menjadi 69,4% pada siklus II. Hasil penelitian menunjukkan bahwa model pembelajaran CPS dapat meningkatkan hasil belajar dan kemampuan berpikir kreatif siswa. Kata kunci: kemampuan berpikir kreatif, hasil belajar, creative problem solving
