Judul: Perencanaan Pengembangan Kerja Sama Kemitraan Multi Pihak Usaha Hutan Rakyat (Studi Kasus Di Desa Citanglar Kecamatan Surade Kabupaten Sukabumi)
Abstrak: Community forests has a long contribution to the economic and ecological either directly to the owner or to the surrounding community. The study was carried out to study and to document the planning of multi stakeholder cooperation partnerships community forest enterprises in Citanglar Village, Surade Subdistrict, Sukabumi. It aims to create a planning model stages. Based on the observation, multi stakeholder involvement are intended to provide a factor of production and business conditions that are condusive to achieving collective goals agreed. Collaborative manager acts as a facilitator in the management of cooperation on community forest development, which is expected to provide confidence and guarantees of business success to the stakeholders. A key factor in the management of multi stakeholder cooperation partnerships are mastery of technology and the development of social capital among actors. This collaborative manager is one option for profession forester

Judul: Evaluasi Keberhasilan Pengelolaan Usaha Hutan Rakyat Jati Di Desa Citanglar Kecamatan Surade Kabupaten Sukabumi
Abstrak: Demand for wood as a raw material for industry is continuing to increase rapidly. There are many ways to meet the need of wood, one of wich is trough the utilization of community forest. Community forest surade has an area of 34,1 Ha which consists three blocks. The focuses of this research include biophysic teak stand (i.e. diameter, height increament, and percent of tree survival), socioeconomic of forest farmer and environmental condition. This research has a purpose to evaluate the progress of teak community forest management in Desa Citanglar, Kecamatan Surade, Kabupaten Sukabumi, both of teak stand condition (biophysical aspect) and forest farmer socio-economic aspects and environmental aspect. Community forest were developed by multy party cooperation among land owners, forest farmers, investor, village government, and collaborative manager. Plants are grouped based on the age, i.e. plant with less than one year old (loated in third block) with a diameter increament of 8.06 cm/year to 12.28 cm/year and height increament of 4.08 m/year up to 9.03 m/year with percent growth of 100%. At the age of 18 months, plants had a diameter increament of 5.43 m/year with percent growth 100%. The socio-economic success can be seen by the final results that is obtained by the farmers income per month wich is Rp 726 500.

Judul: Influenza Specific Immunoglobulin Y Purification from Egg Yolk with Sodium Chloride Precipitation Method
Abstrak: Imunoglobulin Yolk (IgY) yang terdapat dalam kuning telur telah banyak dimanfaatkan untuk imunoterapi dan imunodiagnostik. Salah satu kendala dalam pemurnian IgY dari kuning telur adalah pemisahan Ig dengan lemak, sehingga teknik pemurnian Ig selalu berkembang. Penelitian ini bertujuan untuk melakukan pemurnian IgY dari kuning telur dengan metode pengendapan menggunakan sodium chloride (NaCl) serta melakukan karakterisasi IgY spesifik influenza. Sodium chloride dipilih karena bahan kimia ini relatif murah, ramah lingkungan, dan tidak merusak imunoaktivitas IgY. Kuning telur yang digunakan dalam penelitian ini berasal dari telur ayam layer yang divaksinasi dengan vaksin influenza Flubio® yang berisi virus Influenza A/H3N2, A/H1N1 dan B/Washington. Pemurnian IgY hanya dilakukan pada kuning telur yang mengandung antibodi spesifik influenza. Deteksi keberadaan antibodi spesifik influenza ditentukan dengan uji agar gel presipitasi (AGP) dan metode enzyme linked immunosorbent assay (ELISA). Konsentrasi IgY hasil pemurnian dihitung dengan spektrofotometer dan karakterisasi protein dilakukan dengan metode Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE). Konsentrasi protein dari hasil pemurnian IgY memiliki nilai rata – rata 50,403 mg/mL. Hasil SDS-PAGE menunjukkan enam pita protein, yaitu struktur IgY utuh (174,63 kDa), Apoprotein-LDL (129,77 kDa), rantai berat IgY (66,54 kDa), Fab ( 47,65 kDa), rantai ringan IgY (21,85 kDa), dan β-livetin (36,74 kDa). IgY hasil pemurnian masih dapat berikatan dengan antigen influenza berdasarkan uji ELISA. Hasil penelitian ini menunjukkan bahwa pemurnian IgY menggunakan metode pengendapan NaCl dapat memurnikan IgY dengan struktur utuh, meskipun masih ada dua protein tidak spesifik hasil pemurnian. IgY yang dapat berikatan dengan antigen influenza mengindikasikan prospek pemanfaatannya untuk pencegahan influenza dan imunodiagnostik., Yolk immunoglobulin (IgY) contained in egg yolk has been widely used for immunotherapy and immunodiagnostics. One of the obstacles in IgY purification from egg yolk is separating Ig from fat, so that IgY purification techniques are always developing. This study aimed to purify IgY from egg yolk using sodium chloride (NaCl) precipitation method and to characterize influenza-specific IgY. Sodium chloride was chosen because this chemical is relatively unexpensive, environmentally friendly, and does not impair IgY immunoactivity. The egg yolks used in this study were collected from layer eggs vaccinated with the Flubio® influenza vaccine, which contains the Influenza A/H3N2, A/H1N1 and B/Washington viruses. IgY purification was only carried out on egg yolks containing influenza specific antibodies. The presence of influenza-specific antibodies was determined by the agar gel precipitation (AGP) test and the enzyme linked immunosorbent assay (ELISA) method. The purified IgY concentration was determined using spectrophotometer, and protein characterization was performed using the Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE) method. Protein concentration from purification has a mean value of 50,403 mg/mL . SDS-PAGE result showed six protein bands, namely intact IgY structure (174,63 kDa), Apoprotein-LDL (129,77 kDa), IgY heavy chain (66,54 kDa), Fab (47,65 kDa), IgY light chain (21,85 kDa), and β-livetin (36,74 kDa). The purified IgY still able to bind with influenza antigen based on the ELISA test. The results of this study indicate that purification of IgY using the NaCl precipitation method can purify IgY with intact structure, although there are still two unspecific proteins in the purification results. The resulting IgY can bind to influenza antigens indicating the
