Abstract

This research is to improve understanding of the concept and attitude on the phenomenon that is occurred, so as to understand the concept of the theory of evolution truelly with the next character-based on education is able to avoid misconception of the concept of evolution, which is still a matter of controversy .The experimental data is analyzed with analysis of covariance ( Anacova ), where the pre-test as a covariate, then further testing is done with a different test Least Significances Different ( LSD ). The statistical analysisis assisted by software of SPSS 14 for Windows, conducted with a significance level of 0.05 ( p< 0,05 ) .The Results of Anacova test showed that the Instructional Materials Theory of Evolution with Model Dick & Carey has real significant effect on cognitive achievement with calculation F value of 32. 014 with a value of p = 0.000 is smaller than the alpha value 0.05 which means that the null hypothesisis rejected and the research hypothesisis accepted which states there is influence teaching materials with on Theory of Evolution with Dick & Carey Model of the students’ cognitive achievement and the influence of Instructional Materials of Theory of Evolution by Dick & Carey Model on the attitude result indicates that calculation F value of 40.873 with a value of p = 0.000 is smaller than the alpha value of 0.05 which means that the null hypothesisis rejected and the research hypothesisis accepted which states there is the effect of different device Instructional Materials of Theory of Evolution by Dick & Carey Model for attitude learning outcomes.

Abstract

Limbah cair tahu di lokasi penelitian meliputi amilum sebesar 4,032%, protein 1,415%, pH 4,35, BOD 352,737 mg/l, dan COD sebesar 474 mg/l, dan jumlahnya melebihi melebihi Nilai Ambang Batas. Tujuan penelitian ini adalah: (1) Mengetahui biodegradasi limbah cair tahu menggunakan bakteri indigen yang potensial mereduksi protein dan karbohidrat, pH dan BOD serta COD secara in vitro, (2) Mengetahui hasil penelitian tentang biodegradasi limbah cair tahu dari mikroorganisme indigen dapat digunakan sebagai bahan penyusunan bahan ajar Mikrobiologi Lingkungan di Perguruan Tinggi. Rancangan penelitian eksperimen yaitu uji biodegradasi in vitro menggunakan RAK secara Faktorial, dengan perlakuan pertama yaitu variasi jenis isolat dan waktu inkubasi. Eksperimen kedua dengan perlakuan variasi volume starter dan waktu inkubasi yang berpengaruh terhadap uji reduksi amilum dan protein, pH, BOD, dan COD. Kedua penelitian eksperimen tersebut dianalisis dengan menggunakan Anava Ganda, dilanjutkan uji Duncan Multiple Range Test untuk melihat perbedaan signifikasi variasi uji perlakuan. Hasil penelitian isolat A/F dengan waktu inkubasi 6 hari diperoleh hasil: Protein (1,206-0,191), Amilum (3,651-1,255), pH (4,35-6,25), BOD (352,737-125,095), COD (474-150). Sedangkan isolat M diperoleh hasil: protein (1,189-0,402), amilum (3,488-1,934), pH (4,35-6,2), BOD (352,737-216,152), COD (474-186). Volume starter 5% dan waktu inkubasi 6 hari diperoleh hasil: amilum (3,46 mg/l-1,48 mg/l), protein (1,27 mg/l-0,19 mg/l), pH (4,35-6,5), BOD (318 mg/l-125 mg/l), COD (450 mg/l-180 mg/l). Kesimpulan hasil penelitian, yaitu: Perlakuan variasi volume starter 5% dan waktu inkubasi 6 hari, efisien mereduksi amilum, protein, menaikkan pH, menurunkan BOD dan COD. Hasil penelitian digunakan sebagai bahan penyusun bahan ajar mikrobiologi lingkungan di perguruan tinggi.
