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

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

Gelodok or mudskipper fish are unique fish that have the ability to live in both aquatic and terrestrial areas. Some Indonesian who live in coastal areas use this fish for consumption. Types of mudskipper that are abundant in Indonesia are from the genera of Boleophtalmus, Periophthalmodon and Periophthalmus, where not all types have been studied for their nutritional content. The aim of this study was to analyze the content of Boleophthalmus boddarti and Periophthalmus variabilis. his study compared the nutritional content of the two types sampled from the Kaliwungu Kendal mangrove ecosystem and the Wedarijaksa Pati mangrove ecosystem. The two types of fish sampled were measured by morphometry which included body length, body width and body weight. Then the fish were analyzed for their nutritional content, namely carbohydrates using the Luff Schroorl test method, protein using the Kjeldahl method, fat using the Soxhlet method, iron using the AAS method, and phosphorus using the spectrophotometer method. The results showed that B. boddarti had a higher protein and iron content than P. variabilis . Meanwhile, P. variabilis had higher carbohydrate, fat and phosphorus content than B. boddarti. The difference was due to different feeding behavior, habitat, and types of food in B.boddarti and P. variabilis.

Abstract

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.

Abstract

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 graphene-based 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 oC. 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.

Abstract

Information related to deviants in the near future is often the case by a group of adolescents. Behavior that deviates from anxiety because of a problem in daily life. One way that is taught by Islam by listed in the Qur'an and hadith to reduce anxiety in a person is to do istighfar dhikr. Knowing the beta brain wave activity in anxiety and istighfar dhikr condition can be done using an EEG (Electroencephalogram). Beta waves are brain waves that are detected when a person feels anxious. Beta wave measurement method is calculated based on peaks or troughs per second on the beta signal type frequency (13-30Hz). The method in this research is an experiment with quantitative data collection. The sample used in this study were 8 students in Universitas Islam Negeri Walisongo Semarang with an age range of 20-23 years. The data analysis technique used is bivariate with Paired T-test. The results showed that the average beta wave in anxiety condition was 14.213 Hz and istighfar dhikr was 13.085 Hz. The result of the Paired t-test showed that p = 0.002 (p 0.05) indicating that the decrease in beta waves in the brain is very significant. It shows that istighfar dhikr can reduce anxiety in adolescents.
