Judul: Reformulasi Pengelolaan Sampah Rumah Tangga pada Sumbernya Berbasis Komunitas
Abstrak: The uncreasing of Populastion density is the main caue of solid waste management problem in almost many cities. Conventionally, municipal solid waste management has been the responsibility of local government, with land filling yhe most predominant method of disposal. Local community-based initiatives generally arise because local governments are unable to cope with the rapidly expanding demands made on the formal waste management is the stakeholder participation to reduce and recycle a waste before disposal. Case study in Wedamartani (Sleman, Yogyakarta) and Banjarsari (South Jakarta, Jakarta) gave alternative perspective to waste minimization and recycling scenarios by combaning technical, ecological, economic, socio-ciltural, policy and institutional aspects. Synthesis pattern of waste management supported household to separate waste before disposal and empower waste pickers to make compost from the organic matter. Waste management based on community gave some advantages such as: 10 reducing 57% to 70% from totally amount of waste; 2) cost efficiency 23% to 37% than conventional management; 30 economic added value by selling recyclables, recycle training service and diversification; 4) create social harmony by interactive among the people. The synthesis pattern implementation in Bogor has not done optimally yet. Synthesis pattern can reduce waste up to 58,8%. Operational cost is not covered by waste management fee. The Separated participation of waste must be impoved by public awerness, education and training

Judul: Pemodelan Pengelolaan Sampah Padat Rumah Tangga Berbasis Komunitas di Kota Bogor.
Abstrak: Pengelolaan sampah perkotaan telah menjadi permasalahan global, tidak terkecuali di Bogor. Selaras dengan Undangan Undang No 18/2008, Pemerintah Kota Bogor telah mengelola sampah padat perkotaannya berbasis komunitas, dan berupaya mereduksi sampah dari sumbernya. Saat ini kota Bogor telah menerapkan beberapa cara mengolah sampah di sumbernya, salah satunya dengan mengembangkan konsep Bank Sampah dan menyediakan komposter bagi perumahan. Terdapat 255 Bank Sampah yang telah terdaftar di Bank Sampah Induk Berbasis Aparatur (BASIBA) Kota Bogor, namun hanya 43 yang tercatat aktif dengan kurang dari 1% reduksi dari keseluruhan total timbulan sampah bulanan. Riset ini bertujuan mengidentifikasi partisipasi masyarakat terhadap pengolahan sampah berbasis komunitas serta memodelkan alternatif skenario yang paling efektif dan memungkinkan untuk dapat mengurangi timbulan sampah. Penelitian ini dilakukan selama 6 bulan untuk pengambilan data hingga analisis. Hasil wawancara kemudian dianalisis menggunakan Uji Regresi Logit untuk analisis partisipasi masyarakat terhadap pengelolaan sampah rumah tangga berbasis komunitas serta partisipasi masyarakat terhadap pengurangan (reduksi) timbulan sampah di tingkat rumah tangga. Untuk pemodelan, penelitian ini menggunakan prinsip-prinsip sistem dinamik dan simulasi skenario. Hasil uji regresi logit terhadap 196 responden menunjukkan bahwa tingkat usia, pendidikan dan akses media sosial memiliki pengaruh signifikan terhadap partisipasi masyarakat dalam mengikuti pengolahan sampah rumah tangga berbasis komunitas. Data Pemodelan menunjukkan, bahwa dalam kondisi saat ini (current) dalam lima tahun kedepan akan mencapai 18,7 ribu ton sampah per bulan. Kombinasi dari mengotimalkan Bank Sampah dan komposter serta mengedukasi pemahaman dan partisipasi masyarakat terhadap reduksi timbulan sampah, diestimasi dapat mengurangi timbulan sampah tak terangkut hingga 18% dari situasi saat ini dalam jangka waktu 5 tahun implementasi.

Judul: Pengujian Virus Newcastle Disease Gen VII Isolat Lapang Sebagai Virus Standar Pada Uji Tantang Vaksin
Abstrak: This study was conducted to determine the standard of Newcastle disease virus Gene VII field isolate as a virus challenge to vaccine test. A virus suspension that has previously been tested by HA test then titrated with EID50 using 30 Specific Pathogen Free (SPF) of 10 day old chicken embryonated eggs. In addition, chicken lethal dose50 (CLD50) test were used to determine the virus titer that could cause 50% death of the chicken population. The CLD50 test was used 25 day-old-chickens (DOC) divided into 5 groups. The virus was diluted from 10-1 to 10-8. The 104 to 10-8 dilution of NDV was infected to every group of chicken via eyedrop and intranasal with 0.1 ml/chicken dosage. Haemagglutination test showed that the allantoic fluid were contain high titers of NDV is 512 HAU. The infective NDV that had been titrated by EID50 test showed the virus titers is 109 EID50/0.1 ml or 1010 EID50/ml and the virus titers of CLD50 test e.i 106.48 CLD50/0.1 ml or 107.48 CLD50/ml. These results can be concluded that the NDV Gene VII field isolates were most appropriate to be used as a standard virus to vaccine test
