Abstract

Conventional plastics made from polyethylene (PE), polypropylene (PP), polyvinylchloride (PVC), polystyrene, and poly (ethylene terephthalate) are difficult to decompose. Bioplastics can reduce the amount of toxic waste generated from biological materials other than petroleum.  The combination of cassava pulp and chitosan can be used as a candidate for the manufacture of biodegradable plastics. The optimal drying temperature can produce biodegradable plastics that have good quality. The method used to determine the effect is the mechanical properties test with ASTM D-638M standard and degradation test. The results of this study obtained 6 samples of biodegradable plastic with variations in temperature A=40˚C, B=50˚C, C=60˚C, D=70˚C, E=80˚C and F=90˚C. From the results of the mechanical properties test, the tensile strength values of each sample are A = 0,84 MPa, B = 1,78 MPa, C = 2,24 MPa, D = 1,58 MPa, E = 1,23 MPa and F =0,57 MPa. While the percent elongation value of each sample is A = 11,09%, B = 21,62%, C = 30,25%, D = 15,94%, E = 13% and F = 7,2%. The drying temperature in the process of making biodegradable plastics can affect its mechanical properties, namely the higher the drying temperature used, the lower the tensile strength value and the percent elongation, this is because high temperatures can damage the chemical structure and evaporated sorbitol which serves to increase flexibility. The higher the drying temperature also causes the biodegradable plastic to take longer to degrade. Sample A with the lowest temperature degraded the fastest for 28 days, while sample F with the highest temperature degraded the fastest for 46 days.©2021 JNSMR UIN Walisongo. All rights reserved.

Abstract

The teaching material focuses on the theme of rain which is discussed through the I-SETS approach (Islamic, scientific, environmental, technological, and social). This study aimed to determine the characteristics, feasibility, and enchancement of student character after using teaching materials. This study uses the Research and Development (R D) method in the form of One Group Pretest-Post-test Design. Data collection techniques through interviews, observation, questionnaires, and test results. Data analysis techniques is quantitative descriptive. The characteristics of the teaching materials that had been developed were viewed from three aspects (content, presentation, and language). This characteristic is supported by validating the feasibility of teaching materials of 86.58% had very feasible criteria. Readability results reached a percentage of 53.20% in the appropriate category for students. The results of the application of teaching materials showed that there is no influence yet of teaching materials on the character development and integrated thinking skills which are based on the N-gain test acquisition of 0.169 from the results of the character questionnaire, 0.218 from the results of the character observastions, 0.085 from pretest-posttest mark. This is due to obstacles when learning online and limited number of encounters.

Abstract

The use of composites as an innovative new material is increasing. Composites are made from two or more materials that have different properties. This research was conducted to make multilayer composites and determine the effect of variations in the number of arrangements and the direction of the fiber angles on the physical properties of composites made from ramie fiber and epoxy. The physical properties of the composites analyzed in this study were density, porosity, water absorption, and thickness expansion. The composites in this study were made using the hand layup method with a volume fraction ratio of 30% and the ratio of epoxy and hardener was 2: 1. Before the composite was made, ramie fibers were soaked in 5% NaOH for 2 hours. This study succeeded in making epoxy ramie multilayer composites with variations in the number of arrangements and the direction of the fiber angles. Variations in the number of layers and the direction angle of the ramie fiber in the composite affect the density and porosity of the composite. Variations in the direction of the ramie fiber in the composite affect the water absorption of the composite. Variations in the number and direction of ramie fiber in the composite did not significantly affect the thickness of the composite.

Abstract

Pigmen alami dari daun tanaman Andong (Cordyline fruticosa L.) telah berhasil disintesis secara sederhana dengan merendamnya pada larutan 20 ml HCl 1,47 M. Massa daun dijadikan sebagai variabel bebas penelitian dimana 1 gram hingga 6 gram daun direndam pada larutan kemudian dianalisis sifat optik berupa transmitansi dan absorbansinya. Pigmen yang dihasilkan dalam penelitian ini berwarna merah. Hasil analisis menunjukkan bahwa transmitansi pigmen yang diperoleh menurun secara eksponensial dengan penambahan massa daun. Hasil tersebut menunjukkan pada massa daun 4 gram pigmen telah mengalami saturasi. Adapun absorbansi pigmen yang dihasilkan pada penelitian ini memiliki spektrum absorbansi pada daerah UV hingga spektrum tampak yaitu pada panjang gelombang 200 – 700  nm. Dari hasil analisis absorbansi tersebut, pigmen yang dihasilkan dari penelitian ini secara umum merupakan pigmen jenis flavonoid.  Berdasarkan hasil penelitian ini, disimpulkan bahwa daun tanaman Andong berpotensi sebagai pewarna alami yang selanjutnya dapat diaplikasikan untuk pewarna batik.

Abstract

Pigmen flavonoid dari daun tanaman Andong (Cordyline fruticosa L.) telah dihasilkan secara sederhana dengan merendamnya pada larutan 20 ml HCl 1,5 M. Massa daun dijadikan sebagai variabel bebas penelitian dimana 1 gram hingga 6 gram daun direndam pada larutan kemudian dianalisis absorbansinya. Absorbansi pigmen di dalam penelitian ini diukur menggunakan spektrometer UV-VIS. Pigmen yang dihasilkan dalam penelitian ini berwarna merah. Pigmen yang dihasilkan pada penelitian ini mengabsorb cahaya dengan optimum pada daerah tampak 400-700 nm. Absorbansi maksimum yang dihasilkan oleh tamanan Andong berada pada spektrum tampak adalah 500 nm, sehingga pigmen yang dihasilkan merupakan jenis pigmen flavonoid. Absorbansi pigmen yang tinggi pada spectrum tampak saat dipicu oleh sumber energi dari luar, memberikan harapan pigmen tanaman Andong sebagai bahan absorben yang baik. Berdasarkan kurva absorbansi yang diperoleh, spektrum absorbansi semakin melebar dengan pengaruh massa sehingga baik digunakan sebagai bahan absorben seperti dye pada solar sel berbasis sensitasi (Dye Sensitized Solar Cell).

Abstract

Termoakustik merupakan fenomena fisis dimana perubahan temperatur dapat menyebabkan gelombang (akustik) bunyi atau sebaliknya gelombang (akustik) bunyi dapat menimbulkan perubahan temperatur. Sistem termoakustik sederhana yang menggunakan stack dari bahan plastik dengan panjang 10 cm dan pori-pori berbentuk lingkaran serta resonator tube dari bahan PVC dengan diameter 11⁄4 in. dioperasikan untuk mengetahui pengaruh frekuensi resonansi terhadap penurunan suhunya. Metode yang digunakan untuk frekuensi resonansi, yaitu dengan menentukan panjang resonator tube, kemudian memberikan perlakuan pada resonator tube dengan memberikan gelombang bunyi pada resonator tube, ketika tampilan spektrum pada CRO menampilkan puncak spektrum maksimum dapat dikatakan sudah terjadi resonansi. Transfer energi optimum terjadi pada saat resonansi. Frekuensi resonansi mempengaruhi panjang resonator tube, semakin tinggi frekuensi resonansi maka panjang resonator tube semakin pendek. Hal ini yang menyebabkan kecepatan transfer kalor pada frekuensi resonansi tinggi semakin cepat. Perubahan suhu terkecil terjadi pada frekuensi resonansi 90 Hz, yaitu 0,9 oC. Sedangkan perubahan suhu terbesar terjadi pada frekuensi resonansi 150 Hz, yaitu 1,9 oC dibagian tandon dingin sistem termoakustik sederhana.
