Tujuan penelitian ini untuk mengetahui Pengaruh Model Pembelajaran inkuiri terbimbing berbantu Mind Map terhadap keterampilan proses sains dan hasil belajar siswa kelas VIII SMP Negeri 4 Tarakan. Penilitian ini dilaksanakan pada semester ganjil Tahun Ajaran 2017/2018. Jenis penelitian ini adalah quasi eksperimen dengan rancangan Nonequivalent Control Group Design. Populasi dalam penelitian ini adalah seluruh kelas VIII SMP Negeri 4 Tarakan. Pengambilan sampel dilakukan dengan teknik purposive sampling secara placementest. Sampel dalam penelitian ini adalah kelas VIII-3 dan VIII-5. Teknik pengumpulan data menggunakan dokumentasi, tes dan lembar observasi. Analisis data menggunakan uji-t dan Anakova yang sebelumnya telah dilakukan uji prasyarat analisis berupa uji normalitas dan uji homogenitas. Penghitungan dibantu dengan program SPSS 22.0 for windows. Berdasarkan hasil analisis, dapat disimpulkan bahwa: (1) Terdapat pengaruh positif terhadap keterampilan proses sains, pengaruh inkuiri terbimbing berbantu Mind Map lebih tinggi 80,95 dari pembelajaran multimetode, hasil uji-t data observasi keterampilan proses sains siswa menunjukkan bahwa nilai thitung (10.298) lebih besar dari ttabel , (2) Terdapat pengaruh signifikan terhadap hasil belajar kognitif, pengaruh inkuiri terbimbing berbantu Mind Map lebih tinggi 70,29 dibandingkan pembelajaran multimetode, nilai N-gain pada inkuiri terbimbing berbantu Mind Map sebesar 35% dan nilai N-gain pada pembelajaran multimetode sebesar 15%, hasil uji Anakova menunjukkan nilai F hitung 7.080 dengan signifikansi 0,010 (p < 0,05).

The objective of this research was to know the influence of guided inquiry learning model assisted by Mind Map on science skill process and students learning outcome at eighth grade students of SMP Negeri 4 Tarakan. This research was conducted on the first semester of 2017/2018 Academic Year. The research design was quasi experiment with Nonequivalent Control Group Design. The population of this research was the whole eighth grade students of SMP Negeri 4 Tarakan. The sample taken was conducted by using purposive sampling placementestly. The sample of this research was grade VIII-3 and VIII-5. Technique of collecting data used documentation, test, and observation sheet. The data analysis used t-test and anacova which had been conducted prerequisite test before such as normality test and homogeneity test. The calculation used SPSS 22.0 for windows program as assistance. Based on the analysis result, can be concluded that: (1) There was significant influence on science skill process, the influence of guided inquiry assisted by Mind Map was higher 80,95 than multimetode learning, the t-test data result of students science skill process observation showed that the t count (10.298) was higher than t table. (2) there was significant influence on students cognitive learning outcome, the influence of guided inquiry assisted by Mind Map was higher 70,29 than multimetode learning, N-gain value on guided inquiry assisted by Mind Map was 35% and N-gain value on multimetode was 15%, the Anacova test result showed that Fcount 7.080 with significance 0,010(p
