Judul: Factor Influencing the Decision to Purchase Halal-Labeled Korean Instant Noodles through E-commerce in the Millennial Generation of Jabodetabek
Abstrak: Salah satu produk makanan Korea yang berhasil menarik perhatian masyarakat Indonesia adalah mie instan Korea yang dapat dibeli secara online maupun offline. Namun, sampai saat ini tidak semua mie instan Korea yang beredar di Indonesia berlabel halal. Penelitian ini bertujuan mengidentifikasi karakteristik generasi milenial Jabodetabek serta menganalisis faktor-faktor yang memengaruhi generasi milenial Jabodetabek dalam pengambilan keputusan pembelian mie instan Korea berlabel halal melalui e-commerce. Sampel pada penelitian ini berjumlah 100 responden yang berdomisili di wilayah Jabodetabek. Metode yang digunakan dalam penelitian ini adalah analisis deskriptif dan analisis regresi logistik. Hasil penelitian menunjukkan bahwa variabel pendapatan dan kelompok acuan berpengaruh signifikan terhadap keputusan pembelian mie instan Korea berlabel halal melalui e-commerce pada generasi milenial Jabodetabek., One of the Korean food products that managed to attract the attention of the Indonesian people is Korean instant noodles. However, until now not all Korean instant noodles circulating in Indonesia are labeled halal. This study aims to identify the characteristics of the Jabodetabek millennial generation and analyze the factors that influence the Jabodetabek millennial generation in making decisions to purchase Korean instant noodles labeled halal through e-commerce. The sample in this study amounted to 100 respondents who were domiciled in the Jabodetabek area. The method used in this research is descriptive analysis and logistic regression analysis. The results showed that the variables of income and reference groups had a significant effect on purchasing decisions for Korean instant noodles labeled halal through e-commerce in the Jabodetabek millennial generation.

Judul: Keputusan Pembelian Kosmetik Halal melalui E-commerce oleh Generasi Milenial Jabodetabek
Abstrak: Indonesia sebagai negara dengan populasi Muslim terbesar di dunia dan juga merupakan negara yang menempati urutan kedua setelah India sebagai konsumen terbesar kosmetik halal global. Namun, sampai saat ini belum semua kosmetik yang beredar di Indonesia sudah bersertifikasi halal. Kosmetik menjadi salah satu produk yang paling sering dibeli oleh konsumen di e-commerce, termasuk generasi milenial. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi keputusan pembelian kosmetik halal melalui e-commerce oleh generasi milenial Jabodetabek. Metode yang digunakan adalah metode analisis SEM-PLS untuk mengetahui pengaruh religiusitas, faktor pribadi, faktor budaya, faktor psikologis, kualitas produk dan indikator harga terhadap keputusan pembelian. Indikator yang digunakan pada setiap variable penelitian ini telah dimodifikasi untuk menggambarkan indikator faktor yang memengaruhi pembelian kosmetik melalui e-commerce. Hasil penelitian menunjukkan bahwa religiusitas, faktor pribadi, faktor psikologis, dan indikator harga memiliki pengaruh yang positif dan signifikan terhadap keputusan pembelian kosmetik halal. Sementara, faktor sosial dan kualitas produk tidak memiliki pengaruh yang signifikan terhadap keputusan pembelian kosmetik halal.

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.
