Abstract

Penelitian ini bertujuan untuk menyusun rancangan pembelajaran berbasis sharing dan
jumping task pada konsep hukum kekekalan massa berdasarkan hambatan belajar siswa
dan refleksi diri guru. Metode yang digunakan dalam penelitian ini adalah metode
deskriptif kualitatif. Subjek penelitian adalah siswa kelas X dan XI di salah satu SMA di
Bandung. Instrumen yang digunakan adalah tes kemampuan responden, lembar observasi,
pedoman wawancara, lesson analysis, dokumentasi dan lembar validasi. Hambatan
belajar yang teridentifikasi dari siswa kelas XI yaitu siswa berpikir bahwa dalam reaksi
kimia massa padatan dianggap lebih berat dibandingkan dengan massa cairan dan massa
gas yang terlibat dalam reaksi kimia tidak diperhitungkan. Selain itu, siswa tidak mampu
mengaplikasikan hukum kekekalan massa dalam perhitungan kimia. Hambatan belajar
tersebut dijadikan dasar untuk merancang rancangan pembelajaran. Rancangan
pembelajaran divalidasi dan hasil validasi dijadikan masukan untuk menghasilkan
rancangan pembelajaran yang lebih baik. Di dalam rancangan pembelajaran terdapat
kegiatan demonstrasi, sharing dan jumping task. Rancangan pembelajaran di
implementasikan sebanyak dua kali. Setelah implementasi rancangan pembelajaran
pertama pada kelas X.1, guru melakukan refleksi diri melalui lesson analysis. Hasil
refleksi diri guru dan hambatan belajar yang masih teridentifikasi menjadi dasar untuk
membuat rancangan pembelajaran revisi. Hasil revisi pertama yaitu memperbaiki cara
demontrasi, penambahan percobaan dan alokasi waktu. Hasil revisi kedua yaitu
menambahkan variasi soal aplikasi hukum kekekalan massa pada perhitungan kimia.
Secara umum pengalaman sharing yang terjadi baik di kelas X.1 maupun di kelas X.2
sudah baik. Selain pengalaman sharing yang baik, terdapat juga beberapa siswa yang
mengalami jumping. Hasil implementasi terakhir rancangan pembelajaran pada kelas X.2
menunjukkan bahwa hambatan belajar siswa yang mengganggap massa padatan lebih
berat dibandingkan dengan massa cairan tidak ada lagi, namun sebagian kecil siswa
masih tidak memperhitungkan massa gas dalam reaksi kimia dan tidak sepenuhnya
paham makna dari hukum kekekalan massa.----------This research is aimed at developing a lesson design based on sharing and jumping task
on the concept of conservation of mass by considering the students’ learning obstacles
and the teacher’s self-reflection. The method used in this research was descriptive
qualitative research method. The research subjects were students of grade X dan XI in
one of the high schools in Bandung. The instruments used were a test, observation sheet,
interview guideline, lesson analysis, documentation and validation sheet. Learning
obstacles which were indicated in grade XI students were that they thought that the mass
of solid was heavier than the mass of liquid, and that the mass of gas involved in
chemical reaction was not calculated. Besides, students couldn’t apply the low
conservation of mass in chemical calculation. Those students’ learning obstacles were
used as a basis in developing the lesson design. Lesson design was validated and the
result of it was used to improve the lesson design. This lesson design contained
demontration, sharing and jumping task activities and was implemented twice. The
teacher conducted self-reflection through lesson analysis after the first implementation of
the lesson design in class X.1. The results of the teacher’s reflection and students’
learning obstacles that were still identified were used as a basis in designing the revision
of the lesson design. The results of the first revision were improving the technique of
demonstration, adding experimentation and time management. The result of the second
revision was adding variation for the application of low conservation of mass in chemical
calculation question. In general, sharing experiences occurred in both X.1 and X.2 classes
had been good. Apart from good sharing experiences, some students also experienced the
jumping. The results of the last implementation in class X.2 of the learning design
indicated that students no longer thought that the mass of solid was heavier than the mass
of liquid. However, some students still did not take into account the mass of gas in a
chemical reaction and did not fully understand the meaning of conservation of mass.
