Judul: Analysis of the Factors Influencing Consumer Purchase Decisions Warung Kopi Raja
Abstrak: Kopi merupakan salah satu hasil produk pertanian yang telah memiliki banyak peminat dan paling banyak diperdagangkan di seluruh dunia (International Coffee Organization 2015). Peningkatan tingkat produksi dan konsumsi kopi di Indonesia menyebabkan jumlah kafe dan restoran di Kabupaten Bogor juga meningkat khususnya kedai kopi sehingga memunculkan lingkungan yang kompetitif. Salah satu kedai kopi yang muncul yaitu Warung Kopi Raja yang terletak di Ciampea. Menjadi pendatang baru merupakan tantangan bagi pihak manajemen Warung Kopi Raja untuk berkembang dan bertahan dalam persaingan tersebut. Penelitian ini dilakukan bertujuan mengetahui karakteristik konsumen, mengetahui proses pengambilan keputusan pembelian konsumen, dan menganalisis faktor-faktor yang memengaruhi dalam pengambilan keputusan pembelian konsumen di Warung Kopi Raja. Metode yang digunakan pada penelitian ini menggunakan metode analisis deskriptif dan analisis faktor. Analisis deskriptif digunakan untuk menganalisis karakteristik konsumen dan proses pengambilan keputusan pembelian konsumen. Analisis faktor digunakan untuk menganalisis faktor-faktor yang memengaruhi keputusan pembelian dengan bantuan perangkat lunak Statistical Package for Social Science (SPSS) Version 26., Coffee is one of the agricultural products that has many enthusiasts and is most traded throughout the world (International Coffee Organization 2015). The increase in the level of production and consumption of coffee in Indonesia has caused the number of cafes and restaurants in Bogor Regency to also increase, especially coffee shops, thus creating a competitive environment. One of the coffee shops that emerged was Warung Kopi Raja, located in Ciampea. Being a newcomer is a challenge for the management of Warung Kopi Raja to develop and survive in this competition. This research was conducted with the aim of knowing the characteristics of consumers, knowing the process of making consumer buying decisions, and analyzing the factors that influence consumer buying decisions at Warung Kopi Raja. The method used in this study uses descriptive analysis methods and factor analysis. Descriptive analysis is used to analyze consumer characteristics and consumer buying decision making processes. Factor analysis is used to analyze the factors that influence purchasing decisions with the help of the Statistical Package for Social Science (SPSS) Version 26 software.

Judul: Faktor-Faktor Yang Mempengaruhi Keputusan Pembelian Minuman Kopi Di Malabar Mountain Cafe Kota Bogor
Abstrak: Penelitian ini bertujuan untuk menganalisis bagaimana proses keputusan pembelian serta faktor-faktor yang mempengaruhi keputusan pembelian kopi di Malabar Mountain Cafe. Penelitian ini bersifat studi kasus dengan teknik pengambilan sampling menggunakan metode convenience sampling dan jumlah sampel yang digunakan sebanyak 80 orang. Metode yang digunakan dalam analisis ini yaitu menggunakan analisis deskriptif dan analisis faktor. Analisis deskriptif digunakan untuk mengidentifikasi karakteristik konsumen serta bagaimana proses pengambilan keputusan pembelian konsumen Malabar Mountain Cafe, sedangkan analisis faktor digunakan untuk mengelompokkan variabel-variabel yang memiliki kemiripan untuk dijadikan satu faktor sehingga akan diperoleh faktor-faktor utama yang membentuk keputusan pembelian. Berdasarkan hasil perhitungan analisis faktor, diperoleh tujuh faktor utama yang membentuk keputusan pembelian yaitu 1) harga dan karakteristik produk (8.252), 2) pelayanan dan fasilitas (2.639), 3) promosi dan tempat (1.744), 4) manfaat (1.631), 5) kepribadian (1.356), 6) pengaruh lingkungan (1.259), dan 7) kualitas (1.142).

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.
