Peningkatan Pemahaman Kimia Melalui Paduan Pembelajaran Kooperatif Dan Pemecahan Masalah Kimia Dengan Teknik Pathway
: Improving Students\u27 Understanding of Chemistry through the Combination of Learning Together (LT) Model of Cooperative Learning and Pathway Technique. The aim of the study is to know the effect of combination of LT model of cooperative learning and pathway technique of chemistry problem solving to student\u27s conceptual and algorithmic understanding. The study was carried out in State Senior High School 1 Mataram; the subjects consisted of students of two study groups, XI IPA-2 and XI IPA-6 (treated with LT model of cooperative learning), meanwhile XI IPA-3 and XI IPA-5 were treated with direct instruction. Pathway problem solving served as control variable used by two groups of students. The data were analyzed by One-way Analysis of Variance (ANOVA). It was found that the application of combination of LT model of cooperative learning and pathway technique of chemistry problem solving showed was no difference in the student\u27s conceptual understanding compared to direct instruction. However, the application of combination of LT model cooperative learning and pathway technique of chemistry problem solving showed the significant difference in the student\u27s algorithmic understanding compared to direct instruction. The combined LT model of cooperative learning and pathway technique of chemistry problem solving produced a better result than direct instruction in the achievement of student\u27s algorithmic understanding in chemistry
Desain Sistem Kendali Rotary Pendulum Dengan Sliding-PID
Kebanyakan sistem kontrol yang ada di dunia nyata adalah sistem nonlinier sehingga sulit untuk dikenda-likan. Rotary pendulum adalah sistem yang mensimulasikan sebuah mekanisme kontrol untuk mengatur permasalahan kestabilan. Permasalahan utama dalam desain sistem kendali untuk rotary pendulum adalah menstabilkan batang pendul-um di daerah ekuilibrium pada arm yang digerakkan oleh motor. Pada penelitian ini dilakukan perancangan sistem kendali dengan menggunakan kendali PID dan Sliding-PID. Sliding-PID merupakan gabungan antara Sliding Mode Con-troller dan PID controller. Pemodelan sistem dilakukan dengan Simulink Matlab yang berdasarkan persamaan kine-matika dan dinamika dari sistem. Berdasarkan penelitian ini, dapat disimpulkan bahwa penggunaan kendali Sliding-PID menghasilkan respon yang lebih baik dibandingkan dengan kendali PID. Hal tersebut dapat ditunjukkan dengan nilai maksimum overshoot pada kendali Sliding-PID (0% untuk sudut dan sudut ) lebih kecil daripada kendali PID (9.4664% untuk sudut dan 7.7107% untuk sudut ). Sedangkan waktu yang diperlukan untuk seluruh sistem rotary pendulum (untuk menstabilkan sudut dan sudut ) dengan kendali Sliding-PID (5.8591 detik) lebih besar jika dibandingkan dengan kendali PID (0.5190 detik). Selain itu steady state error dari kendali Sliding-PID (4.94%) lebih besar daripada kendali PID (4.81%)

This study aims to develop chemistry animation media of redox reactions. The study was conducted by using the approach of R & D by Borg & Gall including preliminary study, early product development, validation, limited testing, product revision, and the testing stage. To examine the effectiveness of media on students\u27 motivation and learning outcomes using the stages of classroom action research (CAR) was conducted at SMAN 4 Praya. Data of the study was collected through activity observation, questionnaires, and achievement test. Based on the result, it can be concluded that students\u27 cognitive achievement hasclassical completeness by 61% in cycle 1 and 78 % in cycle 2. The average of students\u27 motivation also improveby 69 in cycle 1 and by 75 in cycle 2 although both are included in the middle category
Pengaruh Model Pembelajaran Kooperatif Tipe Two Stay Two Stray (Tsts) Dengan Pendekatan Brain-based Learning Terhadap Hasil Belajar Kimia Materi Pokok Struktur Atom Dan Sistem Periodik Unsur Pada Siswa Kelas X Sman 1 Kediri
: This study is a quasy experimental that purposing to know the effect of Two Stay Two Stray cooperative learning using brain-based learning approach towards the students' chemistry learning achievements on atomic structure and elements periodic system for X grade students of SMAN 1 Kediri. The learning result used are cognitive aspect. The instrument uses for data collecting are a multiple choice test. Based on the class XB posttest results obtained average value 68 with classical completeness 43.75% while the XC-class average value is 54 with a classical completeness 15.78%. Based on the average value and classical completeness, cooperative learning model two stay two stray (TSTS) with brain-based learning approach does not give a better effect than the conventional method (lecture and discussion) on learning outcomes chemistry subject matter of atomic structure and systems periodic elements in class X of SMAN 1 Kediri. This happens for several reasons, namely internal factors and external factors that affect learning outcomes, either in the form of seriousness, interest and attention, as well as students' mastery learning methods applied
Pengembangan Modul Pembelajaran Larutan Asam Basa Berbasis Pendekatan Mms (Makroskopik Mikroskopik Simbolik) Dan Implementasinya Dalam Pembelajaran
: The research aims were to develop learning modules and learning packages Acid-Base Solvent based on to MMS (Macroscopic, Microscopic, Symbolic) approach and test its effectiveness in learning. Research was conducted in two phases, that is the development of teaching materials in the form of modules and the implementation of modules in the learning activities in classrooms. Developing learning modules and devices using the Dick and Carey model as used by Tucker [1]. The implementation of the development carried out through the design of experimental studies with post-test only non equivalent control group design by taking two classes intact homogenousgroup of five classes available. The results the the development consist of teaching materials in the form of modules, learning tools including syllabi, lesson plans, and assessment instruments. The results of the expert validation of teaching materials in the form of modules, syllabi, lesson plans,and assessment instruments categorized as very good and valid for use. As individuals towards student assessment results of modules categorized as very good, and a group of well categorized. The implementation Acid-base learning module based on the MMS approach has resulted in students\u27 cognitive achievement was significantly better than students in the class with the conventional approach

: The aims of this study were to: 1) generate interactive multimedia of colloidal system which is suitable to be implemented in schools, and to test the effectiveness of an interactive multimedia by: 2) knowing whether concepts mastery of students who use context-based interactive multimedia is better than concepts mastery of students who do not use context-based interactive multimedia on subject matter of colloidal system, and 3) knowing whether critical thinking skill of students who use context-based interactive multimedia is better than critical thinking skill of students who do not use context-based interactive multimedia on subject matter of the colloidal system. The method used in this study was research and development (R&D) according to the model of Borg & Gall\u27s development. The results of the expert validation by 4 validators and limited testing by 10 students showed that the interactive multimedia was very suitable to be used, with scores of 4.21 and 4.36 for expert validation and limited testing, respectively. Field trial testing, using a non-equivalent control group design with 2 class samples, resulted in the concept mastery of probability value of 0.00 (p < 0.05) and the probability of critical thinking skill value of 0.00 (p < 0.05). From this research we can conclude that: 1) context-based interactive multimedia can be developed by means of analyzing the material in each sub material as the basis for developing primary form of product, then tested for it\u27s feasibility, effectiveness, and revised through an expert validation, limited field is considered testing, and main field testing, consecutively, so that the resulting product to be suitable for learning process, 2) concepts mastery of students who use context-based interactive multimedia is better than concepts mastery of students who do not use context-based interactive multimedia on subject matter of colloidal system, and 3) critical thinking skill of students who use context-based interactive multimedia is better than critical thinking skill of students who do not use context-based interactive multimedia on the subject matter of the colloidal system
