Judul: Relasi Kuasa dalam Pengelolaan Sampah di TPA Cipayung Kota Depok
Abstrak: Waste problems faced by the city of Depok such as the accumulation of garbage in some areas of the city Depok due to illegal waste disposal, yet garbage management in landfills and waste disposal in waterbodies across the Depok city. This would be a serious problem because of the production of waste increase every day. Objectives of this study were (1) to analyzethe role of the actors in the way of power in the field of waste management, Depok city, (2) Mapping of actors and interests in waste management, and (3) analyze the relationship and power based actors involved in waste management in Depok area. The results showed that many of the parties involved in waste management, ranging from household or individual persons. The actors interact with each other, intertwined among actors with each other. Each actor can be in the form of individuals or institutions or organizations. Activities of these actors, as well as the relationships between each other, influenced conditions of handling waste. Interests of the parties/actors involved in waste management, as well as the reason why away of handling garbage chosen by individuals/actors, thus affecting the physical appearance of the city of waste side. People cannot wait because the garbage produced everyday, so that using the powers that be in access; the people throw trash on the roadside, unused land and on the river bank/riparian times. There is no one system that can integrate waste management practices, ranging from the source of the waste to landfills. Segmentalisation of handling the waste created as the creativity of the actors in order to exercise power to ensure continuity of interests. Power relations at the level of waste management policy, has shown that the main tasks and functions, as a product of government policy has led to be some waste handled by the agency. But thelinkage/relationship between institutions that are connected by trash, opening opportunities such agencies competing for power imbalances in the control infrastructure, are also strained relations between institutions because of the border and levies.

Judul: SUSTAINABLE WASTE MANAGEMENT (Case Study: TPA Cipayung, Depok)
Abstrak: Kota Depok merupakan salah satu kota di Provinsi Jawa Barat dengan kepadatan penduduk yang tinggi. Tingkat konsumsi masyarakat perkotaan yang tinggi mengakibatkan volume sampah semakin meningkat, sehingga perlu strategi pengelolaan yang berkelanjutan agar TPA Cipayung dapat mengelola dan mengurangi volume sampah yang ada. Penelitian ini bertujuan untuk menganalisis persepsi masyarakat terhadap pengelolaan sampah di TPA Cipayung menggunakan metode analisis deskriptif dan skala Likert, menghitung estimasi kerugian ekonomi dengan menggunakan replacement cost dan cost of illness, dan menganalisis strategi pengelolaan yang berkelanjutan di TPA Cipayung menggunakan analisis SWOT. Hasil penelitian menunjukkan persepsi masyarakat terhadap pengelolaan sampah di TPA Cipayung dalam aspek ekonomi, sosial, dan lingkungan dinilai positif. Estimasi kerugian dengan rata-rata biaya mengganti air bersih yang dikeluarkan responden mencapai Rp.1.351.273,-/tahun sementara untuk biaya berobat sebesar Rp.60.416,-/tahun. Strategi yang dapat dilakukan oleh TPA Cipayung adalah mengembangkan program tentang pengelolaan sampah yang dilakukan secara berkala., Depok city is one of the most densely populated cities in West Java Province. The high level of consumption of urban residents results in increasing waste volumes. Therefore, a sustainable waste management strategy is needed for the Cipayung Landfill to manage and reduce the existing waste volume. This study aims to analyze public perception of waste management at the Cipayung Landfill using descriptive analysis and Likert scale methods, calculate economic loss estimates using replacement cost and cost of illness, and analyze sustainable waste management strategies at the Cipayung Landfill using SWOT analysis. The results show that public perception of waste management at the Cipayung Landfill in the economic, social, and environmental aspects is assessed positively. The estimated loss with an average cost of replacing clean water spent by respondents reached Rp.1,351,273.-/year while for medical costs it was Rp.60,416.-/year. Strategies that can be taken by the Cipayung Landfill are to develop programs on waste management that are carried out regularly.

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.
