Judul: Analysis of the Impact of  MICE Tourism Losses due to the COVID-19 Outbreak in Tangerang Regency
Abstrak: Pandemi COVID-19 yang terjadi sejak Maret 2020 ini telah membuat pola kehidupan baru yang berdampak ke berbagai sektor. Salah satunya pada industri MICE (Meeting, Incentive, Convention, and Exhibition) di Kabupaten Tangerang, berbagai kebijakan dikeluarkan pemerintah untuk mengurangi penyebaran virus ini. Kebijakan seperti pemberlakuan Pembatasan Sosial Berskala Besar (PSBB), penutupan penerbangan dan penutupan sementara hotel-hotel membuat sektor ini mengalami kerugian. Penelitian ini bertujuan dari penelitian ini adalah : (1) Mengetahui kebijakan yang diambil terkait pelaksanaan MICE terhadap adanya COVID 19, (2) Mengestimasi besar kerugian akibat adanya COVID-19 pada sektor MICE di Kabupaten Tangerang, (3)Mengidentifikasi risiko akibat COVID-19 terhadap sektor MICE di Kabupaten Tangerang, (4) Mengidentifikasi strategi dalam upaya pemulihan sektor MICE Tourism pasca COVID-19 di Kabupaten Tangerang. Penelitian ini menggunakan metode analisis deskriptif, Loss of Earning dan penilaian risiko (risk assessment). Estimasi nilai kerugian ekonomi pada sektor MICE di Kabupaten Tangerang sebesar Rp196.301.895.078,00. Analisis risiko pada sektor MICE terdiri dari tiga risiko tinggi dan sembilan risiko menengah. Risiko tinggi mencakup tiga sub kategori pada risiko permintaan yaitu pembukaan semua fasilitas, wisatawan tidak taat protokol kesehatan dan wisatawan berkerumun. Strategi pemulihan sektor MICE yang perlu dilakukan yaitu melakukan penerapan CHSE (Cleanliness, Health, Safety and Environment Sustainability) di setiap hotel dan tempat penyelenggaraan kegiatan MICE lainnya serta meningkatkan kerjasama antara pemerintah, pelaku usaha dan masyarakat dalam melakukan strategi pemulihan MICE.

Judul: Estimasi Nilai Kerugian Ekonomi Akibat COVID-19 Terhadap MICE Tourism di Kota Bogor
Abstrak: Pandemi CoronaVirus Disease 2019 (COVID-19) yang sedang menyebar di seluruh dunia membawa pengaruh yang sangat besar bagi mobilitas manusia. Penyebaran yang cepat membuat pemerintah harus cepat tanggap guna mencegah penyebaran COVID-19. Salah satu tindakan pemerintah dalam mencegah penyebaran COVID-19 adalah membuat kebijakan terkait Pemberlakuan Pembatasan Sosial Berskala Besar (PSBB). Pemberlakuan kebijakan PSBB membawa dampak terhadap kunjungan dan penerimaan pariwisata. Salah satu sektor yang mengalami dampak tersebut adalah sektor wisata MICE (Meeting, Incentive, Convention, and Exhibition) tourism di Kota Bogor. Tujuan dari penelitian ini adalah: (1) mengidentifikasi penurunan wisatawan MICE tourism di Kota Bogor akibat COVID-19, (2) mengestimasi berapa besar kerugian ekonomi MICE tourism akibat adanya COVID-19 di Kota Bogor, (3) mengidentifikasi risiko akibat COVID-19 terhadap MICE tourism di Kota Bogor, (4) mengidentifikasi langkah dan strategi untuk upaya pemulihan MICE tourism di Kota Bogor. Hasil penelitian ini menunjukkan bahwa penurunan wisatawan MICE tourism di Kota Bogor mencapai 62 % atau setara dengan 4.562.530 wisatawan. Kerugian ekonomi MICE tourism sebesar Rp 88.871.494.878. Hasil penilaian risiko pada sektor MICE tourism terdiri dari lima risiko tinggi dan tujuh risiko menengah. Langkah dan strategi pemulihan MICE tourism yang direkomendasikan yaitu melakukan penerapan CHSE (Cleanliness, Health, Safety and Environment Sustainability) di setiap hotel., The Coronavirus Disease 2019 (COVID-19), which spread throughout the world, had a huge impact on human mobility. Rapid deployment makes the government must be responsive to prevent the spread of COVID-19 the implementation of the Large-Scale Social Restrictions (PSBB) which is one of the government actions to prevent COVID-19. The implementation of the PSBB influences the level of tourist visits and receipts One sector that has experienced this impact is the MICE (Meeting, Incentive, Convention, and Exhibition) tourism sector in Bogor City. The objectives of this study are: (1) to identify the decline in MICE tourism tourists in Bogor City due to COVID-19, (2) to estimate the economic loss of MICE tourism due to COVID-19 in Bogor City, (3) to identify risks due to COVID-19 on MICE tourism in Bogor City, (4) identify steps and strategies for efforts to restore MICE tourism in Bogor City. This study indicates that the decline in MICE tourism tourists in Bogor City reached 62 per cent or equivalent to 4,562,530 tourists. The economic loss of MICE tourism is Rp 88.871.494.878. The risk assessment results in the MICE tourism sector consist of five high risks and seven medium risks. The recommended steps and strategies for the recovery of MICE tourism are implementing CHSE (Cleanliness, Health, Safety, and Environment Sustainability) in every hotel.

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.
