Judul: Pendugaan perubahan cadangan karbon di Taman Nasional Meru Betiri
Abstrak: Based on greenhouse gases inventory conducted from 2000 – 2005, land use, land use changes and forestry (LULUCF) contributed approximately 48% of the total emissions of Indonesia, due to deforestation and other forest cover changes at the rate of 1,1 million hectares per year. In the efforts of reducing emissions from LULUCF sector, Indonesia implements Reducing Emission from Deforestation and Forest Degradation-plus (REDD-plus). Meru Betiri National Park (MBNP) was chosen to host a REDD-plus demonstration activity. Carbon stock inventory and monitoring is one of the main activity of the REDD-plus demonstration activity in TNMB. The use of combined remote sensing technology and ground-based inventory in plot scale can be used to estimate carbon stock changes in landscape scale. This study aimed to estimate carbon stock in various land-cover of MBNP and estimate carbon stocks change in MBNP during the period 1989 – 2001, 2001 – 2005, and 2005 – 2010. Carbon stocks measurement was conducted in MBNP during May to July 2010. The measurement was done in Permanent Sample Plots (PSP) which were established by MBNP’s management for carbon stock inventory and monitoring activities. Total of 40 PSPs were available, distributed over various land-covers, namely: primary forest, secondary forest, agro-forestry system, cropland, shrub/bush, grassland, and rubber plantation. This study considered only above ground biomass and above ground carbon. The study found that biomass amount in MBNP ranged at 46,39 Mg.ha-1 – 241,85 Mg.ha-1 and carbon stock amount ranged at 20,31 Mg.ha-1 – 120,93 Mg.ha-1. Primary forest had the highest amount of biomass and carbon stock, while grassland had the lowest amount of biomass and carbon stock in MBNP. During the period of 1989 to 2010, total amount of carbon stock in MBNP has increased at amount of 479.256,12 Mg.ha-1 or on average of 22.821,72 Mg per year. The amount of carbon stock during the period of 1989 – 2001 had decreased at amount of 34.536,86 Mg. The decrease of carbon stocks was caused by deforestation, illegal logging, forest encroachment and tsunami. The amount of carbon stock has increased during the period of 2001 – 2005 at amount of 126.646,67 Mg and during the period of 2005 – 2010 at amount of 398.553,78 Mg. The increase of carbon stocks was caused by intensive forest protection, monitoring of activities on forestland and land rehabilitation involving community in/and surrounding MBNP area, non-governmental organization (LATIN, KAIL), ITTO and PUSPIJAK – Ministry of Forestry.

Judul: Pendugaan Cadangan Karbon dan Serapan CO2 pada Tegakan Taman Hutan Kota Muhammad Sabki di Provinsi Jambi
Abstrak: Hutan memiliki peran penting dalam mitigasi perubahan iklim dan pemanasan global. Hutan menyerap CO2 kemudian menyimpannya dalam bentuk cadangan karbon. Penelitian ini bertujuan untuk mengestimasi kerapatan tegakan, biomassa, cadangan karbon dan serapan CO2 di Taman Hutan Kota Muhammad Sabki (THKMS), Jambi. Parameter tegakan THKMS (yaitu, jenis pohon, diameter, dan tinggi total) diukur dengan membuat 42 petak contoh lingkaran (masing-masing berukuran 0,04 ha) secara sistematis dengan jarak 38 × 38 m. Pendugaan nilai dugaan tegakan dilakukan dengan menggunakan metode stratifikasi dan tanpa stratifikasi berdasarkan zona penggunaan lahan untuk wisata. Hasil penelitian menunjukkan bahwa pendugaan dengan stratifikasi menghasilkan sampling error (SE) yang lebih kecil. Rata-rata jumlah pohon, lbds, biomassa, cadangan karbon, serapan CO2 tegakan THKMS adalah 706 pohon/ha, 21,65 m2/ha, 145,87 ton/ha, 68,56 ton/ha dan 249,04 ton/ha dengan total 706 pohon. pohon/ha, 21,65 m2/ha, 145,87 ton/ha, 68,56 ton/ha dan 249,04 ton/ha., Forest has an important role in the mitigation of climate change and global warming. Forest absorbs CO2 then store it in a form of carbon stock. This study aimed to estimate stand density, biomass, carbon stock and CO2 sequestration in Muhammad Sabki Urban Forest Park (MSUFP), Jambi. The MSUFP stand attributes (i.e., tree species, diameter, and total height) were measured by establishing 42 circular sample plots (each measuring 0.04 ha) in a systematic way with a distance of 38 × 38 m. The estimation of stand attributes was conducted by using stratification and without stratification method based on a land usage zone for tourism. The results showed that the estimation with stratification resulted in a smaller sampling error (SE). The average number of trees, basal area, biomass, carbon stock, CO2 absorption of the MSUFP stands were 706 trees/ha, 21.65 m2/ha, 145.87 tons/ha, 68.56 tons/ha and 249.04 tons/ha with a total of 706 trees/ha, 21.65 m2/ha, 145.87 tons/ha, 68.56 tons/ha and 249.04 tons/ha, respectively.

Judul: Purifikasi dan karakteristik imunoglobulin Y (lgY) kuning telur ayam spesifik Salmonelaenteritidis menggunakan metode sodium dedocyl sulphate poly acrilamide gel electrophoresis (SDS-page)
Abstrak: Penelitian ini bertujuan untuk mengetahui karakter berat molekul fragmen-fragmen lgY yang terbentuk dengan menggunakan metode Sodium Dodecyl Sulphate Poly-Acrylamide Gel Electrophoresis (SDS-PAGE). Bahan lgY didapatkan dari kuning telur ayam Single Comb Brown Leghorn berusia 24 minggu. Lima ekor ayam divaksinasi dengan 1 ml (10 CFU) suspensi bakteri Samonella Enteritidis yang telah dilemahkan dan lima ekor ayam yang tidak divaksinasi sebagai kontrol. Penyuntikan dilakukan pada vena Brachialis dengan pengulangan vaksinasi (booster) dilakukan pada minggu ke-2, ke-3 dan ke-4 seolah vaksinasi pertama. Satu minggu setelah vaksinasi terakhir telur dikoleksi dan diuji Agar Gel Presipitation Test (AGPT).
