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 Kerugian Ekonomi Akibat Covid-19 Terhadap Kunjungan Wisatawan Di Kota Bogor
Abstrak: Tahun 2020 tepat di bulan Maret terjadi penurunan kunjungan wisatawan ke Kota Bogor karena pandemi Covid-19 dan dampak dari kebijakan PSBB (Pembatasan Sosial Berskala Besar). Situasi ketidakpastian di sektor pariwisata yang muncul akibat Covid-19 harus segera diselesaikan melalui mitigasi dan alokasi risiko. Dampak Pandemi Covid-19 juga memukul pelaku usaha di sektor pariwisata. Penelitian ini bertujuan untuk: (1) Mengestimasi penurunan kunjungan wisatawan di Kota Bogor akibat adanya Covid-19 (2) Mengestimasi besar kerugian ekonomi pariwisata akibat adanya Covid-19 di Kota Bogor (3) Mengidentifikasi risiko terhadap pariwisata akibat Covid-19 di Kota Bogor (4) Mengidentifikasi langkah dan strategi yang dilakukan dalam pemulihan pariwisata di Kota Bogor. Metode yang digunakan yaitu pendapatan yang hilang, penilaian risiko, dan analisis deskriptif. Hasil dari penelitian ini menunjukkan pandemi Covid-19 telah menyebabkan penurunan penerimaan sektor pariwisata pada objek wisata, restoran dan hotel. Risiko dengan kelas risiko tinggi adalah kategori risiko permintaan dan kelas risiko menengah pada kebijakan pemerintah dengan semua sub kategori. Langkah yang diambil untuk pemulihan pariwisata adalah meyakinkan bahwasanya pelaku usaha industri pariwisata dan pemerintah sudah mengaplikasikan standar keamanan serta kesehatan yang memadai., In March 2020 there was a decline in tourist visits to Bogor City due to the Covid-19 pandemic and the impact of the PSBB (Large-Scale Social Restrictions) policy. The situation of uncertainty in the tourism sector that has arisen due to Covid-19 must be solved immediately by means of mitigation and risk allocation. The impact of the Covid-19 pandemic has also hit businesses in the tourism sector. This study aims to: (1) Estimate the decline in tourist visitor in Bogor City due to Covid-19 (2) Estimate the economic loss of tourism sector due to Covid-19 in Bogor City (3) Identify risks to tourism due to Covid-19 in Bogor City (4) Identify management steps and strategies in efforts to recovery tourism in Bogor City. This research uses the loss of earnings method, risk assessment, and descriptive analysis. The results of this study showed the Covid-19 pandemic has caused a decline in revenue in the tourism sector at tourism objects, restaurants and hotels. The risk with high risk class is the demand risk category and the medium risk class on government policies with all sub categories. The effort should be tourism recovery are to provide assurance that the government and tourism industry have implemented health and safety standards.

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.
