Judul: Feasibility Analysis of Household Plastic Waste Management and Processing into Paving Blocks (Case Study: Kebon Kopi Village, Cibanteng Village, Bogor Regency)
Abstrak: Rumah tangga yang terletak di Kampung Kebon Kopi terbiasa membakar sampah plastik akibat tidak adanya Tempat Pembuangan Akhir Sementara (TPAS). Untuk itu, kegiatan pengangkutan sampah plastik rumah tangga untuk diolah menjadi paving block merupakan salah satu bentuk implementasi konsep 3R (Reduce, Reuse, Recycle) yang dapat mengatasi permasalahan tersebut. Penelitian ini bertujuan untuk mengestimasi kesediaan masyarakat membayar jasa pengelolaan (iuran) sampah plastik rumah tangga, menganalisis kelayakan finansial agar usaha yang dilakukan dapat berjalan secara layak, serta mengetahui dampak ekonomi dan lingkungan yang dapat timbul. Metode yang digunakan meliputi Contingent Valuation Method (CVM) melalui Willingness to Pay (WTP), analisis kelayakan usaha dengan Net Present Value (NPV), Net Benefit Cost Ratio (BCR), Internal Rate of Return (IRR), dan Payback Period (PP) sebagai indikator, serta analisis deksriptif. Hasil penelitian mengindikasikan bahwa nilai rata-rata WTP rumah tangga belum mampu untuk mendorong mereka melakukan pemilahan sampah, sehingga penetapan iuran berdasarkan nilai WTP minimum dipilih sebagai alternatif yang paling sesuai. Selain itu, hasil analisis kelayakan finansial skenario II dengan menerapkan iuran pengangkutan sampah rumah tangga menunjukkan bahwa proyek pengolahan sampah plastik menjadi paving block layak dijalankan. Terdapat juga potensi dampak yang timbul berupa munculnya lapangan kerja baru dan pengurangan emisi di udara., Households in Kebon Kopi Village are accustomed to burning plastic waste due to the absence of a Temporary Final Disposal Site (TPAS). Therefore, the activity of transporting household plastic waste to be processed into paving blocks is one form of implementing the concept of 3R (Reduce, Reuse, Recycle) that can address this problem. This research aims to estimate the willingness of the community to pay for household plastic waste management services (fees), analyze the financial feasibility to ensure that the business conducted can operate properly, and identify the potential economic and environmental impacts. The methods used include the Contingent Valuation Method (CVM) through Willingness to Pay (WTP), business feasibility analysis using Net Present Value (NPV), Net Benefit Cost Ratio (BCR), Internal Rate of Return (IRR), and Payback Period (PP) as indicators, as well as descriptive analysis. The research results indicate that the average value of WTP of households is not yet able to encourage them to sort waste, so the determination of fees based on the minimum WTP value is chosen as the most appropriate alternative. Furthermore, the results of the financial feasibility analysis for scenario II which includes the implementation of household waste transportation fees indicate that the project of processing plastic waste into paving blocks is feasible. There is also the potential for impacts such as the emergence of new job opportunities and the reduction of air emissions.

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: Leucocytozoonosis Pada Ayam Ras di Sumatera Utara
Abstrak: Di Propinsi Sumatra Utara penyakit leucocytozoonosis pada ayam ras yang disebabkan oleh Leucocytozoon caulleryi dilaporkan oleh Balai Penyidikan Penyakit Hewan wilayah I Medan untuk pertama kali pada bulan Oktober 1982. Penyakit ini mula-mula ditemukan pada ayam broiler berumur 2-3 bulan di Kampung Purwodadi, Kecamatan Medan Sunggal, Kabupaten Deli Serdang. Pada penyidikan terhadap penyakit leucocytozoonosis ini dibeberapa peternakan ayam ras di Kabupaten Deli Serdan Kotamadya Medan ternyata bahwa penyakit ini menimbulkan mortalitas sebesar 20% dan morbiditas 50-100%. Cara mendiagnose yang dipergunakan masih perlu ditingkatkan untuk memperoleh angka mortalitas dan morbiditas yang lebih cermat. Pemakaian gel precipitation test dianjurkan. Penyakit ini diketahui menyerang ayam ras yang dipelihara pada daerah persawahan, daerah yang penuh dengan semak belukar dan keadaan tanah yang lembab dan basah serta banyak air yang tergenang. Ayam yang terserang berumur 2-3 bulan. Diduga penyakit ini ditularkan melalui agas (Culicoides).
