Judul: Penilaian Risiko Operasional pada Proses Bongkar Muat Barang PT Wahana Intradermaga Niaga
Abstrak: PT Wahana Intradermaga Niaga (WIN) merupakan perusahaan yang bergerak dalam bidang bongkar muat barang (stevedoring) di pelabuhan yang menghadapi berbagai risiko yang muncul pada kegiatan operasionalnya. Oleh karena itu, penilaian risiko perlu dilakukan. Tujuan dari penelitian ini adalah untuk mengidentifikasi risiko operasional, menganalisis tingkat penilaian risiko operasional, serta merumuskan solusi yang tepat dalam mengatasi risiko operasional pada PT WIN. Penelitian dilakukan pada bulan September hingga Desember 2022. Penentuan responden menggunakan purposive sampling dengan jumlah responden lima orang. Penelitian ini menggunakan statistika deskriptif, diagram pemetaan risiko, pengendalian risiko Godfrey serta perlakuan risiko Flanagan dan Norman. Hasil penelitian menunjukkan terdapat lima belas risiko operasional yaitu sembilan risiko tergolong tingkat rendah, satu risiko tingkat sedang, tiga risiko tingkat tinggi, serta dua risiko tingkat ekstrem. Upaya perlakuan risiko diprioritaskan pada risiko tingkat ekstrem dan risiko tingkat tinggi agar PT WIN dapat mengendalikan risiko secara optimal. Hasil dari penelitian ini dapat dijadikan acuan oleh PT WIN dalam merumuskan upaya dalam pengendalian risiko.

Judul: Analisis Manajemen Risiko Operasional pada PT Tasun Anugerah Bersama
Abstrak: Permintaan bahan peledak komersial meningkat sejalan dengan peningkatan pembangunan infrastruktur di Indonesia. PT Tasun merupakan salah satu perusahaan jasa yang melayani perizinan dan pendistribusian bahan peledak komersial. Dalam menjalankan bisnisnya, perusahaan menghadapi berbagai risiko operasional namun perusahaan ini belum menerapkan sistem manajemen risiko apapun. Manajemen risiko perlu dilakukan untuk membantu perusahaan dalam mengatasi, mengurangi dan menghindari faktor risiko guna meminimalisir kerugian serta mengoptimalkan kinerja perusahaan. Penelitian ini bertujuan untuk mengetahui lingkup risiko operasional, menganalisis tingkat penilaian risiko dan merumuskan upaya penanganan risiko yang tepat bagi perusahaan. Metode yang digunakan dalam penelitian ini yaitu pengendalian risiko Godfrey serta perlakuan risiko Flanagan dan Norman. Dalam penelitian ini mengintegrasikan sistem manajemen risiko SNI ISO 31000:2018 dan SNI ISO 45001:2018 terkait Keselamatan dan Kesehatan Kerja (K3). Hasil dari penelitian ini menunjukkan terdapat 26 risiko operasional yang terdiri dari empat belas risiko tingkat rendah, sembilan risiko tingkat sedang, dua risiko tingkat tinggi dan satu risiko tingkat esktrem. Upaya perlakuan risiko pada penelitian ini berfokus pada risiko tingkat tinggi dan risiko tingkat ekstrem., The demand for commercial explosives is increasing in line with the increase in infrastructure development in Indonesia. PT Tasun is a service company serving the licensing and distribution of commercial explosives. In running its business, the company faces various operational risks but this company has not implemented any risk management system. Risk management needs to be carried out to assist companies in overcoming, reducing and avoiding risk factors in order to minimize losses and optimize company performance. This study aims to determine the scope of operational risk, analyze the level of risk assessment and formulate appropriate risk management efforts for the company. The method used in this research is Godfrey risk control and Flanagan and Norman risk treatment. In this study, the risk management system is integrated ISO 31000:2018 and ISO 45001:2018 related to Occupational Health and Safety (OHS). The results of this study indicate that there are 26 operational risks consisting of fourteen low-level risks, nine moderate-level risks, two high-level risks and one extreme level of risk. The risk treatment efforts in this study focused on high levels of risk and extreme levels of risk.

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.
