ABSTRAK
Tujuan penelitian ini adalah untuk meningkatkan: (1) kemampuan analisis siswa pada materi stoikiometri melalui strategi Problem Based Learning (PBL) dengan media laboratorium (2) prestasi belajar siswa pada materi pokok stoikiometri melalui strategi Problem Based Learning (PBL) dengan media laboratorium.
Penelitian ini merupakan penelitian tindakan kelas (PTK). Penelitian dilakukan dalam dua siklus, dengan tiap siklus terdiri dari perencanaan, pelaksanaan tindakan, observasi dan refleksi. Subjek penelitian adalah siswa kelas X-MIA 3 SMA Negeri 5 Surakarta yang berjumlah 29 siswa. Sumber data berasal dari guru dan siswa. Teknik pengumpulan data adalah dengan observasi, wawancara, angket, dan dokumentasi atau arsip. Validasi data menggunakan teknik triangulasi . Analisis data menggunakan teknik analisis deskriptif kualitatif.
Hasil penelitian menunjukkan bahwa (1) Penerapan strategi Problem Based Learning (PBL) dengan media laboratorium dapat meningkatkan kemampuan analisis siswa pada materi stoikiometri. Pada siklus I siswa yang tergolong memiliki kemampuan analisis tinggi sebesar 41,38% dan meningkat menjadi 86,21% pada siklus II. (2) Penerapan strategi Problem Based Learning (PBL) dengan media laboratorium dapat meningkatkan prestasi belajar siswa pada materi stoikiometri. Pada siklus I ketuntasan belajar siswa sebesar 55,17% dan meningkat menjadi 86,21% pada siklus II. Simpulan penelitian ini adalah penerapan Based Learning (PBL) dengan menggunakan media laboratorium dapat meningkatkan kemampuan analisis dan prestasi belajar siswa kelas X-MIA 3 SMA Negeri 5 Surakarta.

ABSTRACT
The purpose of the research to improve (1) students’ analytical capability on the subject of stoichiometric through Problem Based Learning (PBL) strategy using laboratory media (2) students’ achievement on the subject of stoichiometric through Problem Based Learning (PBL) strategy using laboratory media.
This research used Classroom Action Research (CAR). The research conducted in two cycles with each cycle consist of planning, performing action, doing observation and reflecting. The subject of this research are 29 students of class X-MIA 3 SMAN 5 Surakarta. The data sources are the teachers and students. The Data collected by doing observation, interviews, questionnaires, and documentation or records. The Data validated by triangulation method. The data analyzed by using qualitative descriptive analysis techniques.
The results of the research showed that (1) the implementation Problem Based Learning (PBL) strategy using laboratory media can enhance students’ analytical capability on stoichiometric. In the first cycle, the students’ who have high analysis capability which are 41,38% extend to 86,21 % in the second cycle. (2) the implementation Problem Based Learning (PBL) strategy using laboratory media can enhance students’ achievement on stoichiometric. In the first cycle, the students’ who have high analysis capability which are 55,17 % extend to 86,21 % on the second cycle. The research concludes that the applying of Problem Based Learning (PBL) strategy using laboratory media can improve students' achievement and analytical capability in class X-MIA 3 SMA Negeri 5 Surakarta.
