Judul: Faktor yang Memengaruhi Perilaku Konsumtif Muslimah Generasi Z terhadap Modest Fashion
Abstrak: Modest fashion merupakan salah satu sektor industri halal yang terus berkembang pesat, khususnya di Indonesia karena memiliki penduduk mayoritas muslim. Tren modest fashion yang cepat berganti saat ini mendorong perempuan muslim semakin konsumtif dalam mengonsumsi pakaian model terbaru, salah satunya muslimah Generasi Z karena cenderung memiliki pengaruh positif yang signifikan terhadap mengikuti tren yang dilihat melalui media sosial. Konsumtif atau berlebihan (israf) merupakan perilaku yang dilarang dalam Islam. Penelitian ini bertujuan mengidentifikasi faktor-faktor yang memengaruhi perilaku konsumtif muslimah Generasi Z terhadap modest fashion. Metode analisis yang digunakan adalah regresi linier berganda dengan menggunakan software SPSS 25. Sampel yang diperoleh sebanyak 100 responden. Hasil penelitian menunjukkan bahwa variabel sosial, pribadi, dan psikologis berpengaruh signifikan terhadap perilaku konsumtif muslimah Generasi Z terhadap modest fashion.

Judul: Faktor yang Memengaruhi Muslim Generasi  Z dalam Minat Beli Produk Kosmetik Halal yang Ramah Lingkungan
Abstrak: Konsumsi muslim global terhadap produk halal terus mengalami perkembangan yang berdampak pada peningkatan konsumsi kosmetik halal. Kegiatan industri yang semakin pesat saat ini juga diiringi dengan meningkatnya permasalahan lingkungan yang menyadarkan banyak pihak mengenai isu lingkungan dan menyebabkan peningkatan konsumsi akan green products termasuk produk kosmetik. Salah satu produk kosmetik halal yang ramah lingkungan adalah kosmetik merek Garnier dan Safi. Penelitian ini bertujuan mengidentifikasi karakteristik responden muslim Generasi Z dan menganalisis faktor-faktor yang memengaruhi muslim Generasi Z dalam minat beli produk halal yang ramah lingkungan. Penelitian ini menggunakan data primer dari 300 responden dengan metode analisis deskriptif dan SEM-PLS menggunakan software SmartPLS 3.3.7. Hasil penelitian menunjukkan bahwa enam dari delapan hipotesis penelitian dapat diterima dan dua lainnya ditolak. Terdapat hubungan secara langsung dan tidak langsung antar variabel penelitian., Global Muslim consumption of halal products continues to experience developments which have an impact on increasing consumption of halal cosmetics. Industrial activities that are currently rapidly increasing are also accompanied by increasing environmental problems that have made many parties aware of environmental issues and have led to an increase in consumption of green products, including cosmetic products. One of the environmentally friendly halal cosmetic products is Garnier and Safi brand cosmetics. This study aims to identify the characteristics of Muslim Generation Z respondents and analyze the factors that influence Generation Z Muslims in buying environmentally friendly halal products. This study uses primary data from 300 respondents with descriptive analysis method and SEM-PLS using SmartPLS 3.3.7 software. The results showed that six of the eight research hypotheses were accepted and the other two were rejected. There is a direct and indirect relationship between research variables.

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.
