Judul: Faktor Keputusan Pembelian Produk Mode Korea Atas Perilaku Imitasi Konsumen
Abstrak: Perilaku meniru cara berpakaian idola Korea akibat paparan media massa dalam tayangan drama Korea maupun girlband atau boyband di Indonesia menjadikan peluang bisnis dalam industri mode. Oleh karena itu penting bagi pemasar untuk mengetahui faktor-faktor yang memengaruhi keputusan pembeli mode Korea. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang berkontribusi dalam keputusan konsumen membeli produk mode Korea. Metode dalam penelitian ini menggunakan analisis faktor dengan pengolahan data menggunakan software SPSS 22. Hasil penelitian ini menunjukkan bahwa ada 11 faktor yang berkontribusi dalam pengambilan keputusan pembelian produk mode Korea yaitu kualitas pemesanan, image produk, keyakinan pada situs, tren sosial, status sosial, produk inti, pelayanan tambahan, gaya hidup, kebutuhan, pengalaman dan kesesuaian pesanan dengan faktor paling dominan adalah kualitas pemesanan.

Judul: Faktor-Faktor yang Memengaruhi Etnosentrisme dan Perilaku Pembelian Produk Korea Selatan di Indonesia
Abstrak: Fenomena Korean Wave memberikan dampak pada etnosentrisme dan perilaku pembelian konsumen Indonesia. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi etnosentrisme dan perilaku pembelian pada produk Korea Selatan di Indonesia. Penelitian ini menggunakan mixed method. Penelitian kuantitatif dilakukan dengan teknik survei pada 348 responden menggunakan instrumen kuesioner. Penelitian kualitatif dilakukan pada 10 orang dengan in-depth interview dan observasi pada retail offline dan online. Analisis data deskriptif dan tabulasi silang menggunakan SPSS 25.0 serta analisis SEM menggunakan Lisrel 8.80. Temuan pada uji hubungan menunjukkan jenis kelamin memiliki hubungan dengan norma subjektif dan etnosentrisme. Jenis kelamin, usia, dan domisili memiliki hubungan dengan citra budaya. Usia dan pekerjaan memiliki hubungan dengan citra negara. Pekerjaan dan pengeluaran memiliki hubungan dengan patriotisme, serta jenis kelamin dan pengeluaran memiliki hubungan dengan perilaku pembelian. Hasil analisis SEM menunjukkan variabel etnosentrisme dipengaruhi oleh citra negara secara negatif signifikan dan patriotisme secara positif signifikan. Hasil analisis SEM juga menunjukkan variabel perilaku pembelian dipengaruhi oleh citra negara secara positif signifikan dan patriotisme serta etnosentrisme secara negatif signifikan. Hasil temuan tersebut dapat dimanfaatkan untuk meningkatkan etnosentrisme konsumen di Indonesia dan pembelian produk dalam negeri dengan dukungan masyarakat Indonesia melalui evaluasi produk yang disampaikan pada pebisnis lokal guna meningkatkan inovasi produk. Pebisnis lokal dapat bekerja sama dengan pemasok lokal dan mendapatkan dukungan dari pemerintah khususnya Kementerian Pariwisata dan Ekonomi Kreatif (Kemenparekraf) dengan menyediakan pelatihan dan pameran produk Indonesia, sehingga meningkatkan kepercayaan masyarakat Indonesia bahwa produk yang dihasilkan oleh pebisnis lokal Indonesia dapat bersaing dengan produk Korea Selatan maupun produk dari negara lain., The Korean Wave phenomenon impacts ethnocentrism and buying behavior of Indonesian consumers. This study analyzed the factors of ethnocentrism and buying behavior of South Korean products in Indonesia. This research used mixed methods. Quantitative research was conducted using a survey technique on 348 respondents with a questionnaire instrument. Qualitative research was conducted on 10 people with in-depth interviews and observations of offline and online retailers. Descriptive data analysis and cross-tabulation used SPSS 25.0 and SEM analysis used Lisrel 8.80. The results of the relationship showed that gender had a relationship with subjective norms and ethnocentrism. Gender, age, and domicile have a relationship with cultural image. Age and job have a relationship with country image. Job and expenditure are related to patriotism. Gender and expenditure are related to buying behavior. SEM analysis shows that ethnocentrism is significantly affected by country image and patriotism is significantly positive. SEM analysis also shows that purchasing behavior is significantly positive affected by country image, while patriotism and ethnocentrism are significantly negatively affected. These findings can be used to increase consumer ethnocentrism in Indonesia and purchase domestic products with support Indonesian people through product evaluations to local businesses to increase product innovation. Local businesses can work with local suppliers and get support from the government, especially the Ministry of Tourism and Creative Economy (Kemenparekraf), by providing training and exhibitions of Indonesian products, thereby increasing the confidence of Indonesian people that products produced by local Indonesian businesses can compete with South Korean products and from other countries.

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.
