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: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
