Padahal, komposisi dan penetrasi pengguna internet di Indonesia didominasi oleh generasi milenial, sehingga kemungkinan generasi milenial terpapar produk fintech payment semakin besar. Hasil survei tahun 2019 menunjukan sebanyak 51% uang milenial dihabiskan untuk keperluan konsumtif dan hanya 2% yang digunakan untuk investasi. Penelitian ini bertujuan untuk mengidentifikasi tingkat literasi keuangan syariah serta menganalisis pengaruh literasi keuangan syariah dan fintech payment terhadap minat investasi generasi milenial DKI Jakarta di pasar modal syariah. Studi ini menggunakan data primer yang diperoleh melalui penyebaran kuesioner pada 100 responden yang berdomisili di DKI Jakarta. Data dianalisis dengan menggunakan metode statistik deskriptif dan SEM-PLS. Hasil penelitian menunjukkan tingkat literasi keuangan syariah generasi milenial DKI Jakarta sebesar 49%; dan terdapat pengaruh literasi keuangan syariah dan fintech payment terhadap minat investasi generasi milenial DKI Jakarta di pasar modal syariah., The level of financial literacy of the Indonesian people towards Islamic finance is still very low. In fact, the composition and penetration of internet users in Indonesia is dominated by the millennial generation, so the possibility for the millennial generation to be exposed to fintech payment products is even greater.

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
