Judul: Comparative Analysis of Customer Satisfaction on Logistic Quality Service of JNE and J&T Express in Jabodetabek
Abstrak: Meningkatnya nilai transaksi e-commerce sejalan dengan peningkatan kebutuhan jasa pengiriman logistik, menjadikan jasa pengiriman seperti JNE dan J&T Express bersaing. Tujuan dari penelitian ini adalah (1) mengidentifikasi perilaku penggunaan JNE dan J&T Express di Jabodetabek, (2) menganalisis tingkat kepentingan atribut-atribut kualitas layanan logistik pada persepsi pengguna JNE dan J&T Express di Jabodetabek, (3) menganalisis kepuasan terhadap layanan JNE dan J&T Express berdasarkan kualitas layanan logistik, dan (4) menganalisis prioritas peningkatan kualitas layanan logistik di JNE dan J&T Express. Analisis yang digunakan adalah analisis deskriptif, Importance Performance Analysis (IPA), Customer Satisfaction Index (CSI), diagram radar, dan independent sample t test. Dari delapan belas atribut, layanan yang penting adalah kondisi paket saat diterima aman dan tidak rusak, perusahaan menyediakan layanan pelacakan pengiriman (web tracking), akurasi menemukan alamat tujuan pengiriman, waktu pengiriman paket sesuai dengan estimasi yang dijanjikan, jaminan ganti rugi oleh perusahaan terhadap paket yang hilang. JNE memiliki lebih banyak atribut yang perlu ditingkatkan, sesuai dengan nilai CSI JNE yang lebih rendah dibandingkan dengan J&T Express sehingga JNE memerlukan upaya lebih banyak untuk perbaikan

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.
