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.

Students' digital literacy is very urgent for online learning and requires learning activities for habituation. The purpose of this study was to investigate the comparison of project activity processes and digital literacy, between learning using electronic workbench and PhET simulation. This research method uses a quasi-experimental design, the sample consists of two groups, namely 29 students in the experimental group and 31 students in the control groupselected through purposive sampling techniqueThe data collection technique used a concept understanding test part of digital literacy, observation of the results of project activities and questionnaires about digital literacy. The data analysis technique used inferential analysis and quantitative descriptive analysis. This study uses two applications, namely electronic workbench in the experimental group and PhET simulation in the control group. The differences identified from the aspect of understanding concepts part of digital literacy and practical procedures. This research shows that the practicum process in a virtual laboratory using an electronic workbench N-gain a better conceptual understanding of literacy and laboratory skills related to practical procedures. In the process of implementing the practicum using an electronic workbench, experience is obtained in carrying out more thorough and accurate practicum procedures. In addition, this virtual practicum requires an adequate understanding of the concept of electronic components and the relationship between the measured electrical quantities.

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 r_yx1x2 = 0.124 dan r_x2x1=_.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.

The objective of this study was to examine the fuzzy c-means clustering (FCM) method to establish the optimum cluster accuracy of zakat potential in Indonesia. A spatial mapping approach is also suggested and can be considered as the first step in knowing the distribution of zakat potential in Indonesia. Furthermore, strategies that can be implemented are formulated to increase zakat collection in Indonesia. Potential zakat data from the National Amil Zakat Agency (Baznas) in 2020 consisting of bank deposits, salaries, agricultural products, plantation products, and staple foods. Each province in Indonesia is used as the proposed variable. In this paper, firstly collecting data on indicators of potential zakat. Second, the FCM clustering algorithm. Third, the results of the FCM grouping are visualized in the form of a mapping. This novel mapping study with FCM was applied in order to analyze clustering accuracy. The FCM results confirm 2 optimum clusters for zakat potential in Indonesia where cluster 2 has more members than cluster 1. Besides, the second cluster only has one variable that has a high value, namely agricultural products, while the rest is in the first cluster. This indicates that the first cluster has a higher potential for zakat. The application of fuzzy c-means (FCM) to obtain the optimum cluster on zakat potential to produce a mapping of zakat potential is a novelty in the field of Islamic economic studies. Finally, the results of the analysis with this approach provide optimum results to strengthen the zakat collection strategy in Indonesia.

Graphene and its related materials have attracted much interest in various applications regarding its exceptional physical, chemical, and mechanical properties. Reduction of graphene oxide (GO) from natural resources is recognized as one of the promising methods for low-cost and large-scale production of graphenebased materials. However, the reduction of GO is generally involves the application of toxic and poisonous substances. To counter this challenge, the green reduction which employ non-hazardous substances was introduced by numerous researchers. In this research, the green reduction of graphene oxide from coconut shell was investigated using rose water at room temperature, 70, 80, 90, and 100 o C. The prepared GO and green reduced GO (rGO) were characterized by X-Ray diffraction (XRD), Scanning Electron Microscope -Energy Dispersive X-Ray (SEM-EDX), Fourier transform infrared (FTIR), and I-V measurement. The low-cost and easy-handle green reduction of GO was obtained by immersing in rose water at room temperature which exhibit carbon to oxygen ratio, C/O of 2.97. Moreover, the effect of oxygenated-functional group to the electrical properties was also strongly discussed.
