ABSTRAK
Tujuan penelitian ini adalah untuk meningkatkan: (1) kemampuan
berpikir kritis siswa pada materi pokok Termokimia melalui penerapan model
pembelajaran Problem Based Learning (PBL) dilengkapi Macromedia Flash,
(2) prestasi belajar siswa pada materi pokok Termokimia melalui penerapan
model pembelajaran Problem Based Learning (PBL) dilengkapi Macromedia
Flash.
Penelitian ini merupakan Penelitian Tindakan Kelas yang dilaksanakan
dalam dua siklus, dengan tiap siklus terdiri atas perencanaan tindakan,
pelaksanaan tindakan, observasi dan refleksi. Subjek penelitian adalah siswa
kelas XI MIA 1 SMA Negeri 2 Karanganyar yang berjumlah 37 siswa. Sumber
data berasal dari guru dan siswa. Teknik pengumpulan data adalah dengan tes
dan non tes (observasi, wawancara, kajian dokumen dan angket). Analisis data
menggunakan teknik analisis deskriptif kualitatif.
Hasil penelitian menunjukkan bahwa: (1) penerapan model
pembelajaran Problem Based Learning (PBL) dilengkapi Macromedia Flash
dapat meningkatkan kemampuan berpikir kritis siswa pada materi pokok
Termokimia. Hal ini dapat dilihat dari persentase kemampuan berpikir kritis
siswa adalah 72,97% pada siklus I dan meningkat menjadi 89,19% pada siklus II,
(2) penerapan model pembelajaran Problem Based Learning (PBL) dilengkapi
Macromedia Flash dapat meningkatkan prestasi belajar siswa pada materi pokok
Termokimia. Peningkatan prestasi belajar siswa dapat dilihat dari aspek kognitif
dan aspek afektif. Pada aspek kognitif persentase ketuntasan siswa pada siklus I
adalah 54,05% dan meningkat menjadi 78,38% pada siklus II. Sedangkan pada
aspek afektif menunjukkan bahwa terdapat peningkatan persentase dari 83,78%
pada siklus I menjadi 91,89% pada siklus II. Sedangkan aspek psikomotor yang
hanya dilakukan pada siklus I sebesar 100%.

ABSTRACT
The purposes of the study were to improve: (1) the student’s critical
thinking ability in the subject matter of thermochemistry by Problem Based
Learning (PBL) learning model with macromedia flash, (2) the student’s
achievement in the subject matter of thermochemistry by Problem Based
Learning (PBL) learning model with macromedia flash.
This research was a classroom action research which was held in two
cycle, each cycle consist of planning, acting, observing and reflecting. The
research subject was the student of class XI science 1 in SMA Negeri 2
Karanganyar that contains of 37 student. The data was taken from teachers and
students. Data were obtained by test and non test (observations, interviews,
document reviews and questionnaires). The data were analyzed using technique
of qualitative descriptive analysis.
The research’s result showed that: (1) the implementation of Problem
Based Learning (PBL) learning model with macromedia flash could improve the
student’s critical thinking ability in the subject matter of thermochemistry. It
could be seen from the percentase of student’s critical thinking ability was
72,97% in cycle I and incerased to 89,19% in cycle II, (2) the implementation of
Problem Based Learning (PBL) learning model with macromedia flash could
improve the student’s learning achievement in the subject matter of
thermochemistry. While the incerased of student’s achievement could be seen
from cognitive and affective aspect. In cognitve aspect, the students learning
completion was 54,05% in cycle I and incerased to 78,38% in cycle II. While in
affective aspect, the percentase incerased from 83,78 % in cycle I to 91,89% in
cycle II. Meanwhile, psychomotoric aspect which was done in cycle one was
100%.
