Judul: Pengaruh Promosi Penjualan terhadap Keputusan Pembelian Impulsif Ibu Rumah Tangga (Studi Kasus: Department Store di Kota Bogor).
Abstrak: Seiring dengan perkembangan zaman yang semakin modern, industri ritel (pedagang eceran) menawarkan berbagai alternatif tempat berbelanja kebutuhan primer untuk memuaskan keinginan dan kebutuhan konsumen. MDS Lippo Plaza Ekalokasari Bogor dan RDS Tajur Bogor merupakan beberapa ritel lokal yang merajai pangsa pasar di Indonesia ditengah maraknya peritel asing yang masuk meramaikan pasar persaingan. Dalam menghadapi persaingan bisnis ritel modern yang ketat, pihak department store melakukan kegiatan promosi melalui promosi penjualan. Tujuan dari penelitian ini yaitu 1) mengidentifikasi karakteristik konsumen di department store 2) mengidentifikasi perilaku konsumen di department store 3) menganalisis pengaruh promosi penjualan terhadap keputusan pembelian impulsif 4) menganalisis bentuk promosi penjualan yang paling berpengaruh terhadap keputusan pembelian impulsif. Metode penarikan sampel menggunakan teknik purposive sampling dengan jumlah sampel sebanyak 100 responden berdasarkan perhitungan rumus Slovin. Data yang diperoleh diolah menggunakan analisis regresi linier berganda. Hasil penelitian ini menunjukkan promosi penjualan yang terdapat di department store berpengaruh positif dan signifikan sebesar 58.8 persen terhadap keputusan pembelian impulsif yang dilakukan oleh konsumen (IRT). Variabel promosi penjualan yang paling berpengaruh terhadap keputusan pembelian impulsif adalah frequent shopper program dan purchase with purchase.

Judul: Analisis Bentuk In-Store Promotion Yang Paling Mempengaruhi Keputusan Impulse Buying Konsumen (Studi Kasus : Konsumen Ramayana Bogor Trade Mall)
Abstrak: Impulse buying behavior usually happens in consumers who come into modern store. This phenomenon motivates retailers to carry out in-store promotion. Because in-store promotion is one of the alternative media to attract consumers to buy a product. Based on this problem will be investigated about: (1) How about the impulsive behavior Ramayana Bogor Trade Mall consumers? (2) How is the impact of in store promotion to influence impulse buying decision by consumers? (3) What is the type of in store promotion that influences decision of impulse buying most? Data which are used consist of primary data and secondary data. Primary data is obtained by survey, while secondary data is obtain by reference study. Data were analyzed by using descriptive methods, multiple linear regression, and Structural equational modeling (SEM) which is supported by Microsoft Office Excel 2007, LISREL 8.30 and SPSS 17.0. Results from descriptive analysis, 75% of respondents used to plan what they want to buy. While consumers always planned purchase but there's always extra stuff they bought without a plan. It can be inferred from 99% of consumers bought additional items while shopping. Based on analysis of Structural Equational Modeling (SEM), influence coefficient (t) of sales promotion, store display and personal selling against impulse buying is a row of 1.14, 0.31, and -0.55 (< table of t = 1.96). It means none variable in store promotion which have an influence on impulse buying behavior of consumers. Based on regression analysis, F values for 2.157 and p-value 0.098 at alpha level 0.10 shows that in-store promotion affects impulse buying decisions Ramayana Bogor Trade Mall consumers. Β values for sales promotions, store displays, and personal selling are respectively 0.085, 0.359, and -0.062. So the type of in-store promotion that influences most consumer buying decisions Ramayana Bogor Trade Mall is a store display. The conclusions of this study were taken based on the results of multiple regression analysis. Structural Equation Modeling (SEM) has high sentitifity rate in it’s counting element variable, so it does not result significant difference.

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.
