Judul: Operational Risk Management of Logistics Companies (Case Study: CV Putra Tunggal Perkasa)
Abstrak: CV Putra Tunggal Perkasa adalah perusahaan logistik yang menyediakan jasa transportasi untuk mitra tunggalnya yaitu PT Pasopa Naga Plastik. Pada proses bisnisnya CV Putra Tunggal Perkasa belum menerapkan sistem manajemen risiko yang tepat yaitu ISO 31000:2018 sehingga masih mengalami berbagai risiko operasional seperti kasus klaim yang terus meningkat. Penelitian ini bertujuan untuk mengidentifikasi; menganalisis risiko; serta merumuskan strategi dalam penanganan risiko bagi CV Putra Tunggal Perkasa. Metode yang digunakan pada penelitian ini yaitu Failure Mode and Effect Analysis (FMEA) dengan memberikan penilaian berdasarkan nilai Risk Priority Number (RPN) dan dilanjutkan penanganan risiko dengan nilai kritis. Penelitian ini diambil bulan Februari hingga bulan Juni 2024 di Kota Padang dengan 7 orang responden dilakukan wawancara mendalam. Diperoleh 19 risiko operasional yang teridentifikasi dengan 5 area lingkup operasional, 5 risiko yang diberikan perlakuan risiko dengan nilai RPN yang berada di atas atau sama dengan nilai kritis yaitu kerusakan truk pada saat proses pengiriman, kecelakaan truk pada saat proses pengiriman, karyawan yang tidak jujur, bencana alam, dan kemampuan PT Pasopa Naga Plastik sebagai mitra menurun., CV Putra Tunggal Perkasa is a logistics company that provides transportation services for its sole partner, PT Pasopa Naga Plastik. In its business processes, CV Putra Tunggal Perkasa has not yet implemented an appropriate risk management system, namely ISO 31000:2018, resulting in various operational risks, such as the increasing number of claims. This study aims to identify, analyze risks, and formulate strategies for risk management for CV Putra Tunggal Perkasa. The method used in this study is Failure Mode and Effect Analysis (FMEA), which assesses risks based on the Risk Priority Number (RPN) and follows up with critical risk handling. The research was conducted from February to June 2024 in Padang City, involving in-depth interviews with seven respondents. The study identified 19 operational risks across five operational areas, with five risks requiring special treatment due to RPN values at or above the critical level: truck damage during delivery, truck accidents during delivery, dishonest employees, natural disasters, and the decreased capability of PT Pasopa Naga Plastik as a partner.

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.
