PENGEMBANGAN LKS DISCUSSION ACTIVITY BERBASIS PENILAIAN KERJA AMALI (PEKA) UNTUK PEMBELAJARAN FISIKA PADA MATERI POKOK SUHU DAN KALOR THE DEVELOPMENT OF WORKSHEET’S DISCUSSION ACTIVITY BASED ON SCIENCE PRACTICAL WORK ASSESMENT FOR TEMPERATURE AND HEAT MATERIALS IN LEARNING PHYSICS

Abstract

Abstrak
Penelitian ini bertujuan untuk : (1) menghasilkan produk LKS Discussion Activity berbasis PEKA agar layak untuk proses
pembelajaran fisika pada materi pokok Suhu dan Kalor, dan (2) mengetahui tingkat ketercapaian keterampilan proses dan
pemahaman konsep siswa pada materi pokok Suhu dan Kalor dengan menggunakan LKS Discussion Activity berbasis PEKA.
Penelitian ini merupakan penelitian pengembangan R&D (Research and Development) dengan menggunakan model
4D.Tahap def ine merupakan tahap awal untuk mendefinisikan permasalahan. Tahap design dilakukan dengan
mengembangkan rancangan awal LKS Discussion Activity dan instrumen penelitian. Tahap develope dilakukan untuk
menghasilkan LKS Discussion Activity yang layak serta untuk mengetahui tingkat keterampilan proses dan pemahaman
konsep siswa. Kelayakan LKS Discussion Activity dilihat dari skor skala 5 dari hasil validasi validator, reliabilitas Alfa
Cronbach hasil pekerjaan siswa terhadap LKS Discussion Activity, dan hasil respon siswa menggunakan skor skala lima.
Tingkat keterampilan proses dilihat dari pekerjaan siswa pada LKS Discussion Activity, sedangkan pemahaman konsep siswa
dilihat dari skor posttest siswa. Tahap disseminate dilakukan untuk penyebaran LKS Discussion Activity dalam skala yang
luas.
Hasil penelitian pengembangan ini adalah : (1) produk LKS Discussion Activity layak dengan kategori sangat baik,
berdasarkan hasil Reliabilitas Alfa Cronbach LKS Discussion Activity mempunyai tingkat reliabilitas sangat tinggi, serta
hasil respon siswa dengan kategori baik. Tingkat ketercapaian keterampilan proses siswa mempunyai nilai rata-rata dengan
kategori baik. Tingkat ketercapaian pemahaman konsep siswa siswa SMA N 7 Yogyakarta pada materi pokok Suhu dan
Kalor dengan menggunakan LKS Discussion Activity berbasis PEKA berdasarkan nilai posttest mempunyai nilai rata-rata
dengan kategori baik.

Abstract
This research is aimed to: (1) produce worksheet’s Discussion Activity based on Sciene Practical Work Assesment so that it
will be feasible for the learning process for temperature and heat materials in physics subject, and (2) f ind out the
achievement of process skills and concept understanding of temperature and heat materials using the Assessment of
worksheet’s Discussion Activity based on Sciene Practical Work Assesment.
This study is a research and development using the 4D .The def ine stage is the early stage in def ining the problems. The
design stage is done by developing the plan f or the worksheet’s Discussion Activity and the research insteruments. The
develop stage is done to produce f easible worksheet’s Discussion Activity and also to f ind out the students’ achievement of
process skills and concept understanding. The f easibility of the worksheet’s Discussion Activity is observed f rom 5 scale score
of the validator’s results, Alf a Cronbach’s reliability of students’ worksheet’s Discussion Activity results, and students’
responses using f ive scale score. The level of process skills can be seen f rom students’ works in the worksheet’s Discussion
Activity while the concept understanding can be seen f rom the students’ posttest scores. The disseminate stage is done t o
distribute worksheet’s Discussion Activity in a large scale.
The results of this research and development are: (1) the worksheet’s Discussion Activity product is f easible f or the physics
learning process have the excellent categories, , based on the result of Alf a Crobach’s reliability, worksheet’s Discussion
Activity 1, 2, and 3 have high reliability, also the students’ responses have the categories goo. The average score for
achievement of process skills is good, while the posttest average in 5 scale score f or concept understanding’s achievement of
the SMA N 7 Yogyakarta’s students in temperature and heat materials using worksheet’s Discussion Activity based on
Assessment of Practical Work in Science is good.
