Judul: Designing Google Cloud-Bases Sales Return Dashboard for Agrotechnology Company
Abstrak: Retur penjualan merupakan risiko bisnis yang krusial bagi perusahaan agroteknologi karena karakteristik produk pertanian segar yang mudah rusak dan memiliki umur simpan singkat. Oleh sebab itu, perangkat analisis dan visualisasi data yang telah dipersonalisasi sesuai kebutuhan pengguna diperlukan untuk menangani isu retur penjualan. Penelitian ini bertujuan merancang dashboard retur penjualan berbasis Google Cloud bagi perusahaan agroteknologi dengan metode User Centered Design. Purwarupa dashboard dirancang dan dievaluasi hingga memenuhi syarat pengguna dan perusahaan. Kemudian, purwarupa final diuji dengan metode black-box testing dan System Usability Scale. Pengujian black-box testing terhadap kegunaan sistem menunjukkan tingkat akurasi pengujian sebesar 100%. Pengujian System Usability Scale menghasilkan rata-rata nilai akhir sebesar 74,5. Nilai tersebut diklasifikasikan ke dalam grade C, berpredikat baik, dan kegunaan sistemnya dianggap dapat diterima. Hasil kedua pengujian mengindikasikan bahwa dashboard retur penjualan berhasil dikembangkan baik dari aspek desain maupun fungsionalitasnya., Sales returns are critical business risk for agrotechnology company due to perishable and short shelf-life characteristics of fresh agricultural products. Therefore, personalized data analytics and visualization tools are required to handle sales return issues. This research aims to design a Google Cloud-based sales return dashboard for agrotechnology company with User Centered Design method. Dashboard prototypes are designed and evaluated to meet user and enterprise requirements. Then, the final prototype was tested using black-box testing method and System Usability Scale. The results of the black-box testing for system usability showed accuracy rates of 100%. The System Usability Scale test resulted in an average final score of 74,5. These results are classified into grade C, adjective rating of “good”, and acceptability rating of “acceptable”. The results of both testsindicate that the sales return dashboard was successfully developed in terms of design and functionality.

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.
