Judul: Factor Analysis Which Affecting Consumer Decisions to Choose E-marketplace Logistics Courier Services in the New Normal Era
Abstrak: Sektor jasa kurir mengalami pertumbuhan secara signifikan seiring dengan peningkatan tren belanja online akibat terbatasnya mobilitas masyarakat karena diterapkannya kebijakan Pembatasan Sosial Berskala Besar yang dikeluarkan oleh pemerintah. Pelaku bisnis jasa kurir logistik harus mengidentifikasi perilaku konsumen sehingga dapat menyediakan layanan pengiriman barang yang mampu menjawab kebutuhan konsumen. Tujuan pada penelitian ini adalah mengetahui karakteristik responden serta menganalisis faktor-faktor yang memengaruhi keputusan konsumen memilih jasa kurir e-marketplace logistik pada era new normal. Penelitian ini menggunakan data primer yang diperoleh melalui kuesioner kemudian diolah menggunakan analisis deskriptif dan analisis faktor menggunakan program SPSS. Hasil penelitian ini menunjukkan bahwa terdapat 14 faktor baru yang terbentuk yaitu (1) komunikasi dan pelayanan, (2) daya saing, (3) pengalaman dan pembelajaran, (4) pengaruh harga, (5) pengaruh lingkungan, (6) perbedaan individu, (7) variasi dan informasi, (8) fasilitas layanan, (9) rekomendasi, (10) demografi, (11) physical evidence, (12) branding, (13) ketersediaan jasa, dan (14) operasional., The courier service sector is experiencing significant growth due to the increasing of online shopping trend caused by the public limitation mobility to implement the Large-Scale Social Restrictions policy issued by the government. Logistics courier services should identify consumer behavior so that they can provide goods delivery services that are able to answer consumer needs. The purpose of this study is to determine the characteristics of respondents and analyze the factors that affecting consumer decisions to choose e-marketplace logistics courier services in the new normal era. This study contained primary data obtained through questionnaires and then processed using descriptive and factor analysis using the SPSS program. The results indicate that there are 14 new factors formed, (1) communication and service, (2) competitiveness, (3) experience and learning, (4) the effect of price, (5) environmental influence, (6) individual differences, (7) variety and information, (8) service facilities, (9) recommendations, (10) demographics, (11) physical evidence, (12) branding, (13) service availability, and (14) operational.

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.
