Judul: Analisis Kelayakan Usaha Pengelolaan Sampah Berbasis Komunitas di Provinsi DKI Jakarta
Abstrak: DKI Jakarta is one of regions with the biggest amount of waste in Indonesia. The amount of waste in 2010 was 6 139.33 tons per day and gradually increases up to 1.38% per year from 1987 to 2010. This research focus on analyze the management of community-based waste in the Village of Kapuk Muara, Penjaringan District, Jakarta Utara Province either based on the analysis of market aspects, technical aspects, management aspects, and socio-economicenvironmental aspects and financial aspects. There are two scenarios were used: (i) full investment from Pertamina CSR programs and (ii) alternative investment by non-governmental program. Based on market aspects, technical aspects, management aspects, and socio-economic aspects of the environment shows that community-based waste management business is feasible. Refer to financial analysis of both scenarios is feasible, respectively in scenario I and scenario II with NPV Rp48 345 205 and Rp130 972 376; IRR of 10.41 and 26.91 per cent; B / C ratio of 1.22 and 2.36 and PBP 7.7 and 4.85 years. Both scenarios are very sensitive to deviation of price the amount of plastic compared to the production of plastics.

Judul: Analisis Kelayakan Pengelolaan Sampah Melalui Bank Sampah (Studi Kasus: Kelurahan Pasar Minggu, Jakarta Selatan).
Abstrak: DKI Jakarta sebagai ibukota negara dan pusat perekonomian harus menghadapi permasalahan pengelolaan sampah yang cukup rumit. Produksi sampah DKI Jakarta mencapai 6.500 ton/hari, sedangkan kapasitas TPST Bantargebang sebagai penampungan sampah utama bagi DKI Jakarta hanya 7.000 ton/hari. Upaya Pemerintah Provinsi DKI Jakarta untuk mengatasi besarnya jumlah produksi sampah melalui Peraturan Daerah No 3 Tahun 2013 yang mewajibkan setiap RW di Jakarta untuk memiliki bank sampah sulit untuk terealisasi karena kendala pembiayaan. Penelitian ini dilakukan untuk menganalisis kelayakan pengelolaan sampah melalui bank sampah di Jakarta. Terdapat tiga skenario yang digunakan yaitu (i) seluruh biaya ditanggung oleh bank sampah dengan asumsi kenaikan jumlah nasabah dan biaya operasional sebesar 10% per tahun, (ii) terdapat iuran nasabah dengan asumsi kenaikan jumlah nasabah dan biaya operasional sebesar 10% per tahun, dan (iii) seluruh biaya ditanggung oleh bank sampah tanpa iuran nasabah dengan asumsi kenaikan jumlah nasabah dan biaya operasional sebesar 15% per tahun. Berdasarkan analisis finansial, skenario I tidak layak untuk dijalankan, sedangkan skenario II dan III layak untuk dijalankan. Masing-masing nilai NPV Rp4.805.792, Rp48.057.001, dan Rp30.617.932; Net B/C 1,06, 1,64,dan 1,41; IRR 1,08%, 9,54%, dan 5,85%; PP 8,4 tahun, 6,2 tahun, dan 6,7 tahun. Jumlah nasabah rumahtangga dan produksi sampah minimum agar bank sampah layak untuk dijalankan adalah 59 nasabah dan 347,38 kg/minggu.

Judul: Evaluation of Influenza Antibody Titers in Serum and Egg Yolk of Layers Vaccinated with Influenza Vaccines.
Abstrak: Influenza belongs to the Orthomyxoviridae family which causes upper and lower respiratory tract infection. The aim of this study was to evaluate influenza-A specific antibody titers from serum and egg yolk of hens vaccinated with quadrivalent influenza vaccines. Three Hy-line Brown layers were vaccinated with quadrivalent influenza type A and B inactivated vaccines. Vaccination was carried out three times at a dose of 0.25 ml/chicken via the intramuscular route. The first vaccination was carried out at 24 weeks of age, then boosters were performed at 28 and 32 weeks of age. Serum and egg yolk were collected every week for 20 weeks since the first vaccination. Influenza A H3N2 and H1N1 antibody titers were determined using hemagglutination-inhibition (HI) test and agar-gel-precipitation (AGP) test. Influenza-A H3N2 and H1N1 specific antibodies were detected in both serum and egg yolk from the first to twenty weeks after the initial vaccination. Highest HI geometric mean titer (GMT) of H1N1 antibody reached 26.67 HIU at nine weeks post first vaccination (p.f.v), while H3N2 antibody reached 26 HIU at six weeks p.f.v. Our result showed that influenza antibodies can be produced in layers using quadrivalent vaccines and layer chickens are able to produce equivalent antibody levels for each influenza subtype.
