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: Pengukuran Jantung Kelinci New Zealand White (Oryctolagus cuniculus) dengan Radiografi Toraks
Abstrak: This research was conducted to evaluate radiographs heart size of anaesthetized New Zealand White rabbits (Oryctolagus cuniculus) under different combination of ketamine and xylazine. The rabbits were divided into three groups. Group A were anaesthetized using a 35 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=5). Group B were anaesthetized using a 40 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=3) while group C were anaesthetized using 45 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=3). Parameter of observation from left laterolateral view were: 1) the apicobasilar length of the heart (AB), 2) the width of the heart (CD), 3) the distance between the cranial edge of the fifth rib and the caudal edge of the seventh rib perpendicular to the spine (R5-7), and 4) the vertical depth of the toraks (H). Parameter of observation from dorsoventral view were: 1) the length of the heart (L), 2) the width of the heart (W), and 3) the width of the thorax (T). The result from the heart parameters observation that were measured in left laterolateral view and dorsoventral view shows theres no significantly differ among the groups (P > 0.05). The vertebrae heart size (VHS) values obtained from the sum of the length of the long and the short axes on left laterolateral view. The long axes mean values (A) were 4.35±0.26 v and the short axes mean values (B) were 3.59±0.30 v, therefore VHS mean values were 7.94±0.49 v. On the dorsoventral view, the length of the heart mean values (L) were 4.32±0.29 cm, the width of the heart mean values (W) were 3.33±0.26 cm, and the width of the thorax mean values (T) were 5.85±0.30 cm. In normal conditions, the width of the heart should be less than two-thirds the width of the thorax and values obtained of 3.33<3.72 it shows that the heart is in the normal range. The best ratio to calculated the normal heart dimension in the left laterolateral view was compared the long axes with the vertical depth of the thorax, whereas in dorsoventral view, the length of the heart was compared with the width of the heart.
