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

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

High cholesterol levels cause several diseases, such as atherosclerosis (narrowing of the arteries), coronary heart disease, high blood pressure, obesity, thyroid disorders, diabetes mellitus, liver disease, and kidney disease. Generally, such checking is carried out invasively in clinical laboratories or hospitals. The checking can be done individually at a lower cost by using non invasive cholesterol measuring devices. This study aims to design and implement an android-based non-invasive cholesterol monitoring device using the TCRT5000 sensor. The tool developed was tested to measure cholesterol levels in 15 respondents aged 20-30 years. The research procedure consisted of several stages, starting with the design stage of the tool, which was carried out by assembling the components; the second stage was the tool coefficient of determination test, the third stage was the accuracy test, and the last stage was the data transfer speed test. The average accuracy of the tool is 83.18%, and the avarage of delay is 8.8 ms. This tool has considerable potential to be used in a telemedicine system that can be accessed remotely regularly to determine the estimated value of cholesterol levels in the blood.
