This research aims to discuss user interface design analysis on the use of Sharia applications based on the technology acceptance model and sharia principles. This research wants to illustrate the assessment results of the initial view and know-how easy to use in a Sharia fintech application, namely Sharia funds. This study interviewed ten respondents from young and old, both young and old, who had not used this application or who were already using it. This study uses a type of qualitative research with the Grounded Theory method to explain the phenomenon specifically. The results showed that the User Interface in Dana Syariah application, which is assessed in terms of Consistency, Personality, Layout,  and control and affordances, could be said almost all views make it easy for users young and old. However, there are some drawbacks, perhaps due to less innovative colors. There are few constraints found for older and above average users who find it difficult to distinguish some of that application's particular functions. This research recommends Islamic fintech application providers to pay better attention to the user interface while inviting academics in Sharia economics to evaluate fintech applications' use to develop a faster Islamic economy.

Produksi sampah plastik di Indonesia sudah sangat mengkhawatirkan. Produksi sampah nasional mencapai sekitar 65,8 juta ton pertahunnya. Berbagai jenis sampah plastik dengan mudah dapat kita temui. Wood plastic composite merupakan salah satu alternatif pemanfaatan sampah plastik. Wood plastic composite merupakan campuran antara bahan plastik sebagai filler dan serbuk kayu sebagai penguat. Penelitian ini bertujuan untuk mengetahui pengaruh variasi jenis plastik terhadap sifat fisik dan mekanik dari Wood plastic composite. Jenis plastik yang digunakan adalah High-density polyethylene (HDPE), polypropylene (PP), dan low-density polyethylene (LDPE), dan sebagai filler digunakan serbuk gergaji gergaji kayu kelapa. Material lain yang ditambahkan adalah serat serabut kelapa sebanyak 2% wt. Proses pembuatan menggunakan proses hot press dengan beban pengepresan sebesar 50 kg dengan suhu 160°C. Untuk mengetahui sifat mekanik dan fisik sampel, dilakukan pengujian tarik mengikuti standar ASTMD639, pengujian impak mengikuti standar ASTM-D6110, pengujian densitas mengikuti standar SNI 03-2105-2006, pengujian daya serap air mengikuti standar SNI-03-2105-2006, dan foto makro menggunakan standar ASTM-E566. Berdasarkan hasil pengujian diperoleh masingmasing uji parameternya, nilai kekuatan tarik tertinggi matriks HDPE sebesar 6MPa. Harga impak tertinggi WPC-PP sebesar 0,249J/mm 2 . Nilai densitas tertinggi WPC-PP sebesar 0,00087g/mm 3 . Terendah WPC-PP sebesar 0,042%. Hasil pengamatan foto makro menunjukkan WPC-PP memiliki distribusi sebaran penguat (SGK&SSK) lebih merata, dibanding WPC-HDPE dan WPC-LDPE.
