ABSTRAKPenelitian ini bertujuan untuk menganalisis peningkatan keterampilan proses sains (KPS) dan sikap ilmiah melalui pemanfaatan hutan dalam pembelajaran biologi terintegrasi tipe connected. Metode penelitian yang digunakan adalah metode weak experiment dengan desain one group pretest-postest dilaksanakan di SMA Negeri di Krayan Kalimantan Timur kelas X tahun ajaran 2011-2012 Pengumpulan data dilakukan melalui pretest dan postest untuk KPS dan sikap ilmiah, lembar observasi aktivitas guru dan siswa untuk menjaring informasi mengenai kegiatan selama pembelajaran berlangsung. Data dianalisis dengan uji perbedaan dua rata-rata, yaitu paired samples T Test dalam program komputer SPSS 16 for windows. Hasilnya terdapat perbedaan signifikan antara skor tes awal dan skor tes akhir KPS dan sikap ilmiah siswa. Rerata N-gain KPS dan sikap ilmiah berturut-turut adalah 0,46 dan 0,35 (sedang). Tingkat presentase keterlibatan siswa pada tiap pertemuan semakin mendekati 100%, artinya hampir semua siswa terlibat aktif dalam melakukan pembelajaran. Dapat disimpulkan bahwa terdapat peningkatan KPS dan sikap ilmiah siswa setelah melalui pemanfaatan hutan dalam pembelajaran biologi terintegrasi tipe connected.ABSTRACTThis study aims to analyze the increase in science process skills (SPK) and the scientific attitude through the use of forests in biology learning integrates connected type.
