Judul: Analisis Faktor-faktor yang Memengaruhi Keputusan Masyarakat dalam Membayar Zakat Profesi di Kota Cilegon, Banten
Abstrak: Zakat profesi merupakan salah satu instrumen redistribusi pendapatan yang dapat meminimalisir masalah kesenjangan ekonomi di masyarakat. Zakat profesi di Kota Cilegon memiliki potensi cukup tinggi dengan realisasi yang terhimpun pada tahun 2021 hanya 7,36 persen dari potensi yang ada. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi keputusan masyarakat dalam membayar zakat profesi di Kota Cilegon, Banten dengan mengambil 80 responden. Penelitian dilakukan kepada masyarakat di Kota Cilegon yang membayar atau tidak membayar zakat profesi. Metode yang digunakan dalam penelitian ini adalah analisis deskriptif dan analisis regresi logistik. Hasil penelitian ini menunjukkan bahwa religiusitas, pengetahuan tentang zakat, pengetahuan tentang zakat profesi, dan altruisme berpengaruh positif signifikan terhadap keputusan masyarakat dalam membayar zakat profesi di Kota Cilegon, Banten.

Judul: Analisis Faktor-faktor yang Memengaruhi Keputusan Masyarakat dalam Membayar Zakat Profesi di Kota Cirebon
Abstrak: Zakat profesi merupakan salah satu instrumen redistribusi pendapatan yang dapat meminimalkan kesenjangan ekonomi di masyarakat. Kota Cirebon memiliki potensi zakat profesi yang cukup besar, tetapi realisasinya hanya sebesar Rp228 juta atau 2,3% dari potensinya sebesar Rp10 miliar. Hal ini mengindikasikan bahwa masih ada dana zakat yang belum terhimpun dari masyarakat Kota Cirebon. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang memengaruhi keputusan masyarakat dalam membayar zakat profesi di Kota Cirebon. Penelitian ini menggunakan metode analisis regresi logistik. Hasil analisis logistik menunjukkan bahwa hanya variabel religiusitas yang berpengaruh positif dan signifikan terhadap keputusan masyarakat dalam membayar zakat profesi di Kota Cirebon., The zakat profession is an income redistribution instrument that can minimize the problem of inequality in society. The city of Cirebon has quite a large potential for the zakat profession, but the realization is only Rp228 million or 2,3% from the targeted potential of Rp10 billion. This indicates that there are still zakat funds that have not been collected from the people of Cirebon City. This research aims to determine the factors that influence people's decisions in paying zakat profession in Cirebon City. This research uses the logistic regression analysis method. The results of the logistic analysis show that only the religiosity variable has a positive and significant effect on people's decisions in paying zakat professionals in Cirebon City.

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.
