Judul: Faktor-faktor yang Memengaruhi Perilaku Pembelian Impulsif dalam Belanja melalui Platform E-commerce pada Konsumen Muslim
Abstrak: Kegiatan belanja online meningkat pesat saat pandemi Covid-19, didukung dengan meningkatnya persentase penetrasi pengguna internet disertai adanya platform e-commerce yang mudah dijangkau mendorong perilaku konsumtif penggunanya (pembelian impulsif). Pembelian impulsif merupakan perilaku pembelian tanpa perencanaan yang terjadi secara spontan, Islam melarang umatnya bersikap israf dan tabdzir dalam konsumsi. Penelitian ini bertujuan menganalisis faktor-faktor yang memengaruhi perilaku pembelian impulsif dalam belanja melalui platform e-commerce pada konsumen muslim. Metode analisis yang digunakan dalam penelitian ini yaitu analisis deskriptif dan SEM-PLS. Sampel yang diperoleh sebanyak 294 responden secara online dari pengguna platform e-commerce yang beragama Islam dan berdomisili di Jawa Barat. Hasil penelitian menunjukkan bahwa terdapat pengaruh yang positif dan signifikan hubungan antara religiusitas terhadap sikap. Namun, perilaku pembelian impulsif tidak dipengaruhi oleh program promosi dan kemudahan yang dirasakan. Oleh karena itu, lembaga terkait diharapkan dapat memberikan edukasi terkait managemen keuangan pada konsumen muslim., Online shopping activities has been increasing rapidly during the Covid-19 pandemic, this also contributed by the increasing percentage of internet user penetration along with availability of easy-to-reach e-commerce platform that encourages user’s consumptive behavior (impulsive buying). Impulsive buying behavior is an act of users on spontaneously buying products without consideration, Islam forbids its people to be israf and tabdzir in consumption. This study aims to analyze the factors that influence the impulsive buying behavior of Muslim consumers shopping through e-commerce platform. The analytical method used in this research is descriptive analysis and SEM-PLS. The sample obtained was 294 respondents online from Muslim e-commerce users in West Java. The results showed that there was a positive and significant relationship between religiosity and attitude. However, impulsive buying behavior is not influenced by promotional programs and perceived easiness. Therefore, the institutions have to educated muslim consumers about financial management.

Judul: Faktor yang Memengaruhi Impulse Buying Behavior Selama Masa Pandemi Covid-19 pada Pengguna E-Commerce Tokopedia
Abstrak: Pandemi Covid-19 memberikan dampak serius terhadap berbagai sektor secara global, khususnya sektor perekonomian. Kondisi saat ini memicu ketakutan, kepanikan dan ketidakpastian sehingga semua orang harus menyesuaikan diri dengan cepat terhadap perubahan. Tokopedia merupakan salah satu e-commerce yang mengalami peningkatan jumlah pengunjung selama pandemi Covid-19. Popularitas mobile shopping membuat perilaku berbelanja tidak lagi dibatasi oleh ruang dan waktu, sehingga pembelian impulsif lebih umum terlihat pada masa ini. Penelitian ini bertujuan menganalisis faktor yang memengaruhi impulse Buying Behavior pada masa pandemi Covid-19. Metode pengambilan sampel menggunakan metode purposive sampling dengan teknik non-probability sampling. Penelitian ini menggunakan Structural Equation Model (SEM) melalui pendekatan Partial Least Square (PLS) dalam pengolahan data. Hasil penelitian menunjukkan bahwa faktor social media fake news dan perceived enjoyment berpengaruh positif dan signifikan terhadap impulse buying pada masa pandemi Covid-19 dengan T-statistic sebesar 4,841 pada faktor perceived enjoyment. Hal ini menandakan bahwa berita fake untuk strategi pemasaran dapat meningkatkan impulse buying dan pelayanan dan kemudahan dalam bertransaksi dapat memberikan kenyamanan kepada konsumen sehinggga dapat meningkatkan impulse buying.

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.
