Judul: Pengaruh Komunikasi Publik Perusahaan terhadap Pencitraan Perusahaan Melalui Program Kemitraan dan Bina Lingkungan pada Masyarakat Sekitar Kebun Malabar, Pangalengan, Kabupaten Bandung
Abstrak: Penelitian ini bertujuan untuk: (1) Menganalisis pengaruh komunikasi publik perusahaan dalam pencitraan PKBL, (2) Menganalisis faktor-faktor yang mempengaruhi keefektifan komunikasi publik perusahaan dalam pencitraan PKBL dan (3) Merumuskan bentuk komunikasi publik dalam membangun citra perusahaan. Penelitian berbentuk survei dilaksanakan di Kebun Malabar, Pangalengan, Kabupaten Bandung dengan penentuan responden (masyarakat) menggunakan metode Cluster Random Sampling sebanyak 80 orang. Pengumpulan data dilakukan dengan penyebaran kuesioner, wawancara mendalam dan pengamatan secara langsung pada subyek penelitian. Untuk melihat pengaruh antar peubah, dianalisis secara statistik menggunakan analisis regresi berganda. Hasil penelitian menunjukkan bahwa (1) Citra perusahaan dan persepsi masyarakat terhadap PKBL sangat positif. Hal ini disebabkan oleh proses komunikasi yang tepat dan efektif. Pola asimetris dua arah, aktivitas masyarakat dalam berkomunikasi dan terbukanya peluang penyampaian umpan balik merupakan cara yang tepat dalam menerapkan komunikasi publik perusahaan dalam pencitran PKBL; (2) Faktor-faktor yang berpengaruh positif terhadap keefektifan komunikasi publik perusahaan dalam pencitraan perusahaan melalui PKBL adalah profil individu masyarakat, lingkungan fisik dan sosial, profil humas perusahaan dan proses komunikasi publik perusahaan; (3) Profil individu masyarakat yang berpengaruh positif adalah usia, tingkat pendidikan dan tingkat pendapatan. Lingkungan fisik dan sosial yang berpengaruh positif adalah fasilitas, teknologi, dukungan tokoh masyarakat dan kelembagaan masyarakat. Profil humas perusahaan yang berpengaruh positif adalah tingkat komitmen, dukungan struktur humas perusahaan dan dukungan biaya. Masing-masing peubah tersebut berpengaruh positif terhadap proses komunikasi publik perusahaan. Selanjutnya, proses komunikasi publik perusahaan yang berpengaruh positif terhadap keefektifan komunikasi adalah pola komunikasi publik perusahaan, aktivitas komunikasi publik perusahaan dan keterdedahan terhadap komunikasi publik perusahaan; serta (4) Perumusan bentuk komunikasi publik untuk membangun citra perusahaan yang dinilai tepat adalah dengan menggunakan pola komunikasi dengan model asimetris dua arah yang dikombinasikan dengan pola komunikasi ko-orientasi.

Judul: Persepsi Pemangku Kepentingan Terhadap Program Kemitraan Dan Bina Lingkungan Badan Usaha Milik Negara Serta Efektivitas Implementasinya (Studi Kasus PT. Pertamina (Persero) di Komunitas Seberang Ulu II, Sumatera Selatan)
Abstrak: This study is about the stakeholders’ perception of partnership program and community development (PKBL) and the effectiveness of the implementation which doing by PT. Pertamina in Seberang Ulu II community, South Sumatera. This study use qualitative and quantitative approach with triangulation and survey method. Informant is the staff from External Relation, Human Resources and Environment function. Respondent is people who are the employee of PT. Pertamina Retail Region II, the local government staffs and Seberang Ulu II community, both participants and non participants of PKBL. This study focused on the assessment of the effectiveness of PKBL according to guidelines of ISO 26000, and also the correlation between stakeholders’ perceptions and PKBL success rate for identifying the effectiveness of PKBL implementation. Based on result, PKBL implementation can only fill two of ISO 26000 core subjects, namely good governance organizations issue, and also community involvement and community development issue. It means that according to ISO 26000, the effectiveness of PKBL implementation is low. Beside that, the majority of stakeholders’ perception is Corporate Social Responsibility and the success rate of PKBL implementation is low. There’s significant correlation between perception of Corporate Citizenship and Corporate Social Responsibility with success rate of PKBL, but not in Corporate Philantrophy. Therefore, the effectiveness of the implementation of PKBL is directly proportional to success rate of PKBL, then the effectiveness of PKBL implementation is low too.

Judul: Pemurnian dan karakterisasi protein inhibitor RNA helikase virus hepatitis C
Abstrak: Hepatitis C virus (HCV) infection is the second most common chronic viral infection in the world with global prevalence. This infection is contribution to chronic hepatitis and liver cirrhosis, often leading to hepatocellular carcinoma. There is no effective drug and vaccine available against HCV. The current standard treatment, a combination of pegylated interferon-α with ribavirin, is limited by its suboptimal response rate in a significant patient population, side effects, and affordability. Therefore, development of effective drug is needed. One approach to find out the candidate of antiviral drug is to discover the inhibitor of enzyme that essential for virus replication, such as RNA helicase. Streptomyces chartreusis 5-095 produce the inhibitor of HCV RNA helicase. The aim of this study was to purify the protein inhibitor which has inhibition activity against ATPase activity of RNA helicase HCV from S. chartreusis 5-095. The supernatant of culture S. chartreusis 5-095 exhibited high inhibiton activity against ATPase activity of RNA helicase HCV (approximately 72%) at 10 days of incubation. The extracellular protein inhibitor was partially purified by procedures of precipitation with ammonium sulfate to 65% saturation and gel filtration (Sephadex G50) using methanol water solution (4:6) as an eluen. The purity of protein inhibitor was monitored by SDS PAGE. The protein inhibitor showed a relative molecular mass were estimated to be 14 kDa and increased the purity 23,08 fold than those of the crude protein. The specific activity and IC50 after purification were 13,1338 U/mg and 0,0767 mg/mL, respectively. The activity of purified protein inhibitor showed its stability over pH range from 5-8 and optimum at pH 7,4. The inhibition activity showed its stability up to 70% at temperature 100 oC. The purified protein inhibitor relatively stable its activity at storage in the range of -20 oC to room temperature for 35 days.
