Judul: Faktor-Faktor yang Memengaruhi Kesadaran (Awareness) Generasi Muda Provinsi Lampung terhadap Tabungan Haji
Abstrak: The waiting list for hajj in Indonesia, which ranges from 10-46 years, is an obtstacle for prospective pilgrims who will carry out the hajj. As many as 63-67% of elderly pilgrims have problems with metabolism or chronic diseases. Therefore, BPKH begins to socialize the young hajj program which aims to raise awareness of saving for hajj from an early age. This study aims to analyze the awareness of young generation towards hajj saving in Province Lampung and the factors that influence it. The data of this research is collected by conducting questionnaires to the young generation in Lampung Province. The sample that used was 100 respondents. The method used in this research is descriptive analysis and logistic regression. The analysis results showed that religiousity, access to information, and perspective had significant positive relationship on the awareness of young generation in Lampung Province towards hajj saving.

Judul: Faktor-faktor yang Memengaruhi Keputusan Generasi Milenial dan Zilenial Terhadap Kepemilikan Tabungan Haji di Jawa Barat.
Abstrak: Haji merupakan salah satu rukun Islam yang wajib dilaksanakan bagi umat Muslim jika mampu. Tetapi saat ini masa tunggu haji mencapai puluhan tahun, sehingga perlu adanya perencanaan keuangan bagi generasi milenial dan zilenial, salah satunya melalui pembukaan tabungan haji. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang memengaruhi keputusan generasi milenial dan zilenial terhadap kepemilikan tabungan haji di Jawa Barat. Responden dalam penelitian ini adalah generasi milenial dan zilenial yang sudah memiliki tabungan haji di Jawa Barat. Penelitian ini menggunakan data primer dari 200 responden yang dianalisis dengan metode analisis deskriptif dan SEM-PLS menggunakan software SmartPLS 4 dan SPSS versi 26. Hasil penelitian menunjukkan bahwa pada generasi milenial variabel biaya dan motivasi berpengaruh positif signifikan, sedangkan pada generasi zilenial variabel motivasi dan kepercayaan berpengaruh positif signifikan., Hajj is an obligation for Muslims who have the ability. The long waiting period to perform Hajj is the reason for the need to plan this worship as early as possible. This study aims to determine the factors that influence the decisions of millennials and zillennials towards ownership of Hajj savings in West Java. Respondents in this study are millennials and zillennials who already have Hajj savings in West Java. This study used primary data from 200 respondents who were analyzed using descriptive analysis methods and SEM-PLS using SmartPLS 4 software and SPSS version 26. The results showed that in the millennial generation the variables of cost and motivation had a significant positive effect, while in the zillennial generation the variables of motivation and trust had a significant positive effect.

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.
