Judul: The Effectiveness of E-WOM through Instagram as Viral Marketing Media for Agroedutourism during the COVID-19 Pandemic
Abstrak: Pembatasan Kegiatan Masyarakat (PPKM) selama masa pandemi COVID-19 membuat sektor pariwisata terdampak. Destinasi wisata Kota Bogor, yaitu Kampung Agroeduwisata Organik Mulyaharja harus tutup sementara dan melakukan promosi melalui media sosial pasca-PPKM. Salah satu strategi promosi yang efektif dilakukan di media sosial adalah electronic word of mouth dimana calon pengunjung dapat mendapat rekomendasi dan informasi berdasar pengalam pribadi yang membantu memutuskan kunjungan. Tujuan dari penelitian ini adalah untuk menganalisis efektivitas e-WOM dan media sosial Instagram sebagai media pemasaran viral Kampung wisata di masa pandemi COVID-19. Metode yang digunakan adalah metode kuantitatif dengan kuesioner online dan didukung dengan data kualitatif melalui wawancara mendalam. Responden pada penelitian ini adalah followers Instagram @visitmulyaharja berjumlah 44 orang yang didapatkan melalui teknik accidental sampling. Hasil penelitian menunjukkan bahwa penilaian responden terhadap dimensi electronic word of mouth yang paling kuat adalah valensi pendapat, efektivitas strategi promosi di masa pandemi ternyata efektif untuk meningkatkan perhatian dan ketertarikan followers, dan terdapat faktor-faktor yang berhubungan dengan efektivitas strategi promosi, yaitu dimensi intensitas berhubungan kuat dengan share, konten berhubungan kuat dengan search, dan valensi pendapat berhubungan kuat dengan interest, Restrictions on Community Activities (PPKM) during the COVID-19 pandemic impacted the tourism sector. The Bogor City tourist destination, namely the Mulyaharja Organic Agroedutourism Village, must temporarily close and promote through post-PPKM social media. One of the effective promotional strategies carried out on social media is electronic word of mouth where potential visitors can get recommendations and information based on personal experiences that help decide on a visit. The purpose of this study was to analyze the effectiveness of e-WOM and Instagram social media as viral marketing media for Kampung Wisata during the COVID-19 pandemic. The method used is a quantitative method with an online questionnaire and is supported by qualitative data through in-depth interviews. Respondents in this study were Instagram followers @visitmulyaharja totaling 44 people obtained through accidental sampling technique. The results showed that the respondents' assessment of the strongest electronic word of mouth dimension was opinion valence, the effectiveness of promotional strategies during the pandemic was effective in increasing followers' attention and interest, and there were factors related to the effectiveness of promotional strategies, namely the intensity dimension associated Strongly related to share, content was strongly related to search, and opinion valence was strongly related to interest.

Judul: Kajian Stabilitas Inti Super Berat dengan Nomor Atom 110 Sampai dengan 200 Menggunakan Model Inti Tetesan Cairan
Abstrak: Liquid droplets of nucleic models can be derived equations to estimate the binding energy, binding energy per nucleon, the most stable isotope, and the condition of the occurrence of spontaneous fission. The equations are then converted into a numerical equation form which is then inserted into the MATLAB programming language. Based on the results of the calculations have been carried out in this study, super-heavy nuclei will undergo spontaneous fission in the Z = 135. At Z = 135 the energy needed to create the nucleus undergoing fission or activation energy is very small at around 0:48 MeV. Above Z = 135 the activation energy is negative, it means to form a nucleus with Z> 135 needed some energy. Then at Z = 135 the ratio Z2 / A is 48.86, almost reaching requirement ratio Z2 / A where the nucleic will undergo spontaneous fission is 49. Binding energy per nucleon for super-heavy nuclei up to Z = 200 is about 7 - 5.5 MeV, together with a range of light nuclei are stable. So there may be a super-heavy nuclei are stable at Z <135 and above Z> 135 there will be no stable nucleic
