Judul: The Effectiveness of Instagram Marketing Communications in Shaping Intentions for Return Visits to the Kampung Labirin Tourism Object
Abstrak: Pengembangan wisata berbasis pemberdayaan masyarakat menjadi fokus utama Pemkot Bogor dalam upaya pemulihan perekonomian, salah satunya berlokasi di objek wisata Kampung Labirin yang memanfaatkan Instagram sebagai media komunikasi pemasaran utama. Pemanfaatan media sosial dinilai dapat meningkatkan jumlah kunjungan terlebih untuk membentuk niat kunjungan kembali sehingga tujuan penelitian ini adalah menganalisis efektivitas komunikasi pemasaran Instagram dalam membentuk niat kunjungan kembali. Penelitian ini menggunakan metode kuantitatif didukung data kualitatif dengan pemilihan 44 responden menggunakan teknik accidental sampling dan diolah menggunakan uji korelasi Rank Spearman dan chi square. Pengunjung yang merupakan pengikut akun Instagram menilai sangat baik terhadap konten yang memperhatikan aspek etika. Efektivitas komunikasi pemasaran dinilai efektif dalam menarik perhatian, menimbulkan ketertarikan dan menimbulkan keinginan untuk berkunjung kembali. Faktor-faktor yang berhubungan dengan efektivitas komunikasi pemasaran adalah kejelasan informasi, aspek etis, dan daya tarik visual yang ketiganya berhubungan cukup kuat dengan efektivitas komunikasi pemasaran pada tahap perhatian, keinginan, dan tindakan., The development of community empowerment-based tourism is the main focus of the Bogor City Government in an effort to restore the economy, one of which is located in the Kampung Labirin which utilizes Instagram as the main marketing communication medium. The use of social media is considered to be able to increase the number of visits especially to form return visit intentions so that the purpose of this study is to analyze the effectiveness of Instagram marketing communications in forming return visit intentions. This study uses quantitative methods supported by qualitative data with the selection of 44 respondents using accidental sampling techniques and processed using the Rank Spearman correlation test and chi square.

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
