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: Pengaruh Promosi Penjualan di Dalam Toko Terhadap Keputusan Impulse Buying pada Konsumen Carrefour Hypermarket Lebak Bulus, Jakarta Selatan.
Abstrak: Ritel modern di Indonesia berkembang lebih cepat dibandingkan dengan ritel tradisional. Salah satu jenis ritel modern yang memperlihatkan laju pertumbuhan yang cukup melejit adalah hypermarket (salah satu contohnya adalah Carrefour). Banyaknya ritel modern yang hadir di Indonesia menyebabkan timbulnya kondisi persaingan antar ritel yang semakin kompetitif. Kondisi ini menuntut para peritel untuk mengembangkan strategi yang efektif dan kreatif. Salah satu strategi yang dapat dilakukan peritel adalah dengan melakukan kegiatan promosi penjualan di dalam toko. Promosi penjualan di dalam toko didasari dengan semakin ketatnya persaingan antar merek yang dijual di dalam area toko dan bertujuan untuk mendorong konsumen melakukan pembelian impulsif (impulse buying). Kegiatan promosi penjualan di dalam toko dapat berupa promosi free sample, bonus pack, in-store display, purchase with purchase, dan price discount. Tujuan pada penelitian ini adalah: (1) Menganalisis perilaku impulse buying konsumen Carrefour hypermarket Lebak Bulus; (2) Menganalisis pengaruh promosi penjualan di dalam toko Carrefour hypermarket Lebak Bulus terhadap keputusan impulse buying konsumen; dan (3) Menganalisis bentuk-bentuk promosi penjualan di dalam toko (free sample, bonus pack, in-store display, purchase with purchase, dan price discount) yang paling berpengaruh terhadap keputusan impulse buying pada konsumen Carrefour hypermarket Lebak Bulus. Pada penelitian ini data yang diperoleh diolah dengan menggunakan Software Microsoft Office Excel 2007, Minitab 14, Statistica 9 dan software SPSS 15. Data dianalisis menggunakan metode deskriptif, crosstab (tabulasi silang), chi-square, korelasi kanonikal dan regresi linier berganda. Berdasarkan hasil pengolahan dan analisis data didapatkan hasil bahwa 64% konsumen Carrefour hypermarket Lebak Bulus berjenis kelamin perempuan dan mayoritas berusia 15-24 tahun dengan persentasi sebesar 24%. Sebesar 60% konsumen Carrefour hypermarket Lebak Bulus baik laki-laki maupun perempuan merencanakan pembeliannya. Sisanya sebesar 33% yang tidak selalu (terkadang) merencanakan pembeliannya dan sebesar 7% tidak merencanakan pembeliannya. Walaupun konsumen selalu merencanakan pembelian tetapi tetap saja ada produk tambahan yang mereka beli tanpa direncanakan sebelumnya. Hal ini dapat dilihat dari 96% konsumen membeli produk tambahan saat berbelanja seperti membeli makanan dan minuman ringan (cokelat, permen, dan soft drink), buah dan sayuran, serta toiletris (peralatan mandi dan kosmetik). Berdasarkan analisis regresi linier berganda diperoleh hasil bahwa promosi penjualan di dalam toko mempengaruhi keputusan impulse buying pada konsumen Carrefour hypermarket Lebak Bulus (F=17.129, p-value = 0.000). Bentuk promosi penjualan di dalam toko yang berpengaruh terhadap keputusan impulse buying konsumen Carrefour hypermarket Lebak Bulus adalah price discount, purchase with purchase, bonus pack, dan free sample. Berdasarkan analisis chi-square, karakteristik tingkat pendidikan konsumen memiliki hubungan dengan pembelian impulsif.

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.
