Abstract

Based on interviews and observation at VIII grade of SMP Negeri 1 Merbau Mataram Lampung Selatan showed that the student’s science prosess skill was low. This study aimed to determine the effect of guide inquiry model in increase student’s science process skill. The design pretest-posttest was non-equivalent. The sample were class VIII B and VIII C whice selected by cluster random sampling. Research data obtained from the pretest, posttest, and observation of student activity sheets. Analysis using the t test and U test using SPSS 16 and using student activity classification. Results of this study indicate that students' science process skills in the experimental class had no significant difference compared to the control class (experimental = 68.46; control= 66.06). Thus the use of guided inquiry model of the material structure and function of tissues in plants affect the students skill acquisition process.Berdasarkan hasil wawancara dan observasi kalas VIII SMPN 1 Merbau Mataram Lampung Selatan diketahui proses pengembangan ketrampilan proses sains masih rendah. Penelitian ini bertujuan untuk mengetahui pengaruh model inkuiri terbimbing terhadap keterampilan proses sains siswa. Desain penelitian ini pretest-postes tak ekuivalen. Sampel penelitian ini adalah kelas VIII B dan VIII C yang dipilih dengan teknik cluster random sampling. Data penelitian yang diperoleh dari pretes, postes, dan lemba robservasi aktivitas siswa. Analisis menggunakan uji t dan uji U dengan menggunakan program SPSS 16 serta mengunakan klasifikasi aktivitas siswa. Hasil penelitian ini menunjukkan bahwa keterampilan proses sains siswa pada kelas eksperimen memiliki perbedaan yang tidak signifikan dibanding kelas kontrol (eksperimen= 68,46; kontrol= 66,06). Dengan demikian penggunaan model inkuiri terbimbing pada materi struktur dan fungsi jaringan pada tumbuhan berpengaruh dalam penguasaan keterampilan proses siswaKata kunci : keterampilan proses sains, model inkuiri, struktur dan fungsi tubuh tumbuhan

Abstract

The provision of mycorrhizal fungi makes phosphorus available in the soil because mycorrhizae play a role in dissolving phosphorus bound to the soil. Soybeans need phosphorus, a significant limiting factor for plant growth and production. The study aims to determine the optimal dose of vesicular-arbuscular mycorrhizal (VAM) inoculation and SP36 fertilizer on Tanggamus soybean varieties. The study was arranged using a Split Plot Design (RPT), with the main plot, namely the MVA dose consisting of 4 levels, namely: without mycorrhiza (m0), mycorrhiza 5 g.plant-1 (m1), 10 g.plant-1 (m2), 15 g.plant-1 (m3); and the subplot is SP36 fertilizer consisting of 4 levels, namely: Without SP36 (f0), SP36 7.7 g.plant-1 (p1), 11.5 g.plant-1 (p2), 15.4 g.plant-1 (p3). There were 16 treatment combinations consisting of 3 replications and 48 experimental units. The variables observed were plant height, root fresh weight, shoot fresh weight, flowering days, number of seeds per plant, and seed weight per plant. The results showed that the treatment of vesicular-arbuscular mycorrhiza 15 g.tan-1 with SP36 fertilizer 7.7 g.tan-1 increased growth, especially at a plant height of 50.68 cm (4.84%) and increased soybean plant yields, as shown by seed weight of 52.33 g.tan-1 (60.18%) compared to the treatment of SP36 fertilizer without mycorrhizas (15.4 g.tan-1).
