Judul: Operational Risk Management Supply Chain in Asana Sincerity Dorm
Abstrak: Asana Sincerity Dorm merupakan salah satu unit hotel yang milik PT. Aerowisata. Dalam kegiatan operasionalnya, Asana menghadapi risiko-risiko yang muncul pada proses bisnisnya. Risiko tersebut perlu dianalisis untuk dicari aksi pencegahannya sehingga dapat menghindari atau mengurangi dampak bagi perusahaan. Tujuan dari penelitian ini adalah untuk mengetahui kejadian risiko serta skala dampaknya, penyebab risiko serta tingkat kemunculannya, dan aksi pencegahan risiko yang dapat diterapkan oleh Asana. Metode penelitian yang digunakan yaitu House of Risk (HOR) untuk mengidentifikasi dan menyusun aksi pencegahan risiko. Terdapat 14 kejadian risiko yang disebabkan oleh 21 agen penyebab risiko yang muncul dalam proses bisnis Asana. Aksi pencegahan yang efektif untuk diterapkan adalah menyediakan layanan penitipan barang, follow up rutin kepada pihak GITC, penjadwalan permintaan data, melakukan double cross check, dan pemberian reminder oleh staff. Kata kunci: manajemen risiko, House of Risk, risiko operasional, Asana Sincerity Dorm is a hotel unit owned by PT. Aerowisata. In its operational activities, Asana faces risks that arise in its business processes. These risks need to be analyzed in order to find preventive actions so they can avoid or reduce the impact on the company. The purpose of this study was to determine risk events and the scale of the impact, the causes of risk and the level of the occurrence, and risk prevention actions that can be implemented by Asana. The research method used is House of Risk (HOR) to identify and compile risk prevention actions. There were 14 risk events caused by 21 risk-causing agents that appeared in the Asana business process. The effective preventive actions to be implemented are providing goods storage services, routine follow-up to GITC, scheduling data requests, conducting double cross checks, and providing reminders by staff.

Judul: Analysis of The Operational Risk Management of Agrotourism PTPN. VIII Gunung Mas Puncak, Bogor West Java
Abstrak: Manajemen risiko merupakan dasar bagi sebuah perusahaan untuk mencapai targetnya. Dengan mengelola risiko, perusahaan dapat mengurangi kerugian, sehingga dapat meningkatkan keuntungan dan keberlanjutan dari sebuah bisnis. Tujuan dari penelitian ini adalah untuk mengidentifikasi risiko yang berkaitan dengan perusahaan, menilai kemungkinan dan dampak risiko, dan merumuskan saran untuk mitigasi risiko. Penelitian dilakukan di unit bisnis Agrowisata PTPN. VIII Gunung Mas. Data yang dikumpulkan dengan mewawancarai pemangku kepentingan internal dan eksternal (pelanggan). Hasil penelitian menunjukan terdapat 13 risiko yang teridentifikasi yang dikelompokan menjadi empat kategori yaitu SDM, sistem, sarana dan prasarana dan eksternal. dari 13 risiko tersebut, terdapat tiga risiko ekstrem, tiga risiko tinggi, empat risiko sedang dan tiga risiko rendah. Selain itu, penilaian risiko dari perspektif pelanggan menunjukan perbedaan dalam jenjang pemahaman antara pemangku kepentingan internal dan eksternal, terutama pada risiko pelayanan. Strategi diprioritaskan untuk meminimalisir tingkat risiko ekstrem dan risiko tinggi ke tingkat risiko sedang., Risk management is a foundation for a company to meet the company’s target. By managing the risk, a company would reduce losses so that enhance the profit and sustainability of the business. The objectives of the study are to identify operational risks dealing by the company, to assess the probability and the impact of the risks, and to formulate suggestions to mitigate the risks. The study was taken place at the agritourism business at Gunung Mas, a business unit of PTPN VIII. Data were collected by interviewing both internal and external (customer) stakeholders. The results showed there were 13 identified risks which were divided into four categories which is human resources, system, facilities, and external. From the 13 risks, there were three risk in the extreme level, three risk in the high level, four risk in the medium level, and three risk in the low level. In addition, risk assessment from the customer's perspective shows differences in the level of internal and external stakeholders understanding, especially on service risk. The strategy is prioritized to minimize the extreme level and high-level risks to the medium level.

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.
