Judul: Efektivitas Kampanye Komunikasi #VaksinHarusLengkap dalam Mendukung Program Vaksinasi Covid-19.
Abstrak: Berbagai langkah preventif dilakukan untuk mengatasi penyebaran virus Covid-19, salah satunya dengan program vaksinasi Covid-19. Akan tetapi, masih terdapat masyarakat yang ragu dan kurang percaya untuk menerima vaksin Covid19. Oleh karenanya, pemerintah membentuk Komite Penanganan Covid-19 dan Pemulihan Ekonomi Nasional (KPCPEN). Melalui media Instagram @lawancovid_id, KPCPEN melakukan berbagai kampanye salah satunya kampanye #VaksinHarusLengkap. Tujuan penelitian ini adalah untuk menganalisis efektivitas kampanye #VaksinHarusLengkap dalam mendorong masyarakat untuk dapat mengikuti program vaskinasi Covid-19 dengan dosis lengkap. Penelitian menggunakan metode survey dengan instrumen kuisoner melalui platform Google-Form yang disebarkan kepada 70 responden sebagai pengikut akun @lawancovid19_id. Hasil penelitian menunjukkan bahwa efektivitas kampanye berada pada kategori tinggi untuk aspek tingkat pengetahuan dan berada pada kategori sedang untuk aspek tingkat sikap dan perilaku. Hubungan nyata ditemukan antara karakteristik individu pada variable usia dan tingkat pendidikan dengan efektivitas kampanye komunikasi pada aspek sikap. Selain itu, terdapat hubungan nyata lainnya yang ditemukan antara strategi pesan kampanye dengan efektivitas kampanye komunikasi., Various preventive steps have been taken to overcome the spread of the Covid-19 virus, one of which is the Covid-19 vaccination program. However, some people are doubtful in receiving the Covid-19 vaccine. Therefore, the government formed the Committee for Handling Covid-19 and National Economic Recovery (KPCPEN). Through the media Instagram @lawancovid_id, KPCPEN conducts various campaigns, one of which was the #VaksinHarusLengkap campaign. This study aimed to analyze the effectiveness of the #VaksinHarusLengkap campaign in encouraging people to take part in the full dose of the Covid-19 vaccination. The research used a survey method with a questionnaire instrument via the Google-Form, distributed to 70 respondents of the @lawancovid19_id’s followers. This research shows that the effectiveness of communication campaigns has the highest rate for changes of knowledge, and a moderate rate for changes of attitudes and bebehaviorsSignificant relationships were found between individual characteristics on indicators of age and level of education with the effectiveness of communication campaigns on the attitude aspect. In addition, there is another real relationship between message strategies and the effectiveness of communication campaigns.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
