Abstract

Fisika adalah cabang ilmu pengetahuan alam (sains) yang mempelajari tentang fenomena alam secara ilmiah. Fenomena alam yang ada dan terjadi di bumi dan di langit adalah kajian sains dan sekaligus objek tafakkur kepada Allah. Pemahaman pengetahuan agama Islam (Al-Qur’an dan as sunnah) menjadi dasar untuk mempelajari fisika. Penelitian ini bertujuan untuk mengetahui hubungan hasil belajar mata kuliah fisika dasar dan pengetahuan agama Islam (Tafsir) terhadap kemampuan mengintegrasikan bagi mahasiswa Jurusan Pendidikan Fisika FITK UIN Walisongo. Hasil penelitian menunjukkan bahwa hubungan kemampuan mengintegrasikan pengetahuan agama Islam dengan konsep dasar fisika masih rendah ditunjukkan dengan nilai ryx1x2 = 0.124 dan rx2x1=.0,137.  Kondisi ini dikarena kurikulum yang ada di Jurusan Pendidikan Fisika belum menunjukkan integrasi yang jelas, yaitu muatan kurikulum yang ada belum terintegrasi walaupun sudah ada pengembangan paradigm kestuan ilmu. Integrasi nilai-nilai Islam dapat ditanamkan kepada mahasiswa melalui ranah materi, metode pembelajaran, sikap pendidik, dan lingkungan.

Abstract

The research of solar cell with using dye from natural materials as a sensitizer in a dye-sensitized solar cell (DSSC) continues to grow. One advantage of the DSSC is does not require a material with high purity so that the production cost is relatively low. This research aims to analyze the characteristics of the absorption band of teak leaf extract. Extraction of teak leaves dissolved in a mixture of ethanol and acetic acid with a variation ratio of 1: 0, 1: 1 and 5.66: 1, resulting in a solution of each color reddish yellow, reddish brown and dark red. Absropsi test results with UV-Vis spectrometer showed that there are peaks in the absorbance in the visible region, ie at wavelengths between 500 nm to 560 nm. This shows that the dye material of teak leaf extract may work or absorb the green color. While absobption other peaks are also found in pektrum wavelength of 580 nm, 600 nm and 660 nm, each of which can absorb the green color yellow, orange and red. ©2016 JNSMR UIN Walisongo.

Abstract

Wasted-plastic which is a hardly-decomposed material was one of the major problems of trash-recycling management in Indonesia. Replacing a common plastic with biodegradable plastic was one of the solution to reduce the amount of undecomposed-materials in the enviroment. Therefore, the aim of this resarch is to study how to synthesis cassava shell based biodegradable plastic and to analyse the effect of kitosan addition on cassava shell based biodegradable plastic properties. There are three basic characterization processes performed to analyse the sample properties, i.e mechanical test, FTIR and biodegradability test. Kitosan enhanced the mechanical and biodegradability properties of samples. The elongation-percentage decreased down to 8,57% along with the increasing the amount of kitosan concentration. FTIR data indicated the presence of O-H, N-H, C-H, C=C, NO2 and C-O organic functional group on biodegradable plastic samples. Kitosan reduce the decomposition process of samples due to its hydrophilicity. Sample with highest concentration of kitosan decomposed at the longest time up to 14 days. . ©2017 JNSMR UIN Walisongo.

Abstract

Penelitian pemanfaatan fabrikasi plastik biodegradable telah dikembangkan karena bersifat ramah lingkungan dan terbarukan. Tujuan penelitian ini untuk membuat plastik biodegradable dengan filler berupa (kitosan dari limbah kulit udang dan tepung ampas ubi kayu dari limbah ampas ubi kayu) dengan penambahan sorbitol sebagai matrix, serta menganalisa menggunakan uji kuat tarik dengan standar ASTM D-638M, FTIR dan biodegradasi. Hasil penelitian ini didapatkan 4 sampel plastik biodegradable dengan variasi perbandingan komposisi massa filler (kitosan:tepung ampas ubi kayu) masing-masing sampel yaitu A (1,30: 0,70) gr, B (1,35: 0,65) gr, C (1,40: 0,60) gr dan D (1,45: 0,55) gr. Dari hasil uji sifat mekanik didapatkan nilai kuat tarik masing-masing sampel yaitu A (1,01±0,11) MPa, B (1,32±0,08) MPa, C (1,66±0,03) MPa dan D (1,97±0,06) MPa. Sedangkan nilai persen elongasi dari masing-masing sampel yaitu A (23,58 ± 1,39) %, B (16,67 ± 0,20) %, C (11,01 ± 1,32) % dan D (8,11 ± 0,72) %.  Sedangkan nilai persen elongasi dari masing-masing sampel yaitu A (22.89%), B (15.90%), C (10.56%) dan D (7.85%). Penambahan komposisi massa kitosan terbukti mampu meningkatkan nilai kuat tarik dan modulus young plastik biodegradable, namun untuk nilai persen elongasinya menurun. Uji FTIR menunjukkan bahwa di dalam plastik biodegradable terdapat gugus fungsi C-H, O-H, C≡C, C=N, C=C dan C-O yang merupakan gugus organik. Tingginya intensitas ikatan C≡C pada sampel dengan komposisi massa kitosan paling banyak menyebabkan ikatan lebih sukar merenggang/diputus, karena memiliki energi ikatan rata-rata yang tinggi, sehingga menambah nilai kuat tarik dan memperlambat proses biodegradasi.
