Judul: Pola Sebaran dan Perubahan Tutupan Hutan dan Lahan pada Ekosistem Transisi di Kabupaten Bungo, Tebo, dan Tanjung Jabung Barat Provinsi Jambi
Abstrak: Land cover change is an issue crucial in the process of change of GHG (Green House Gass). This study examines patterns of forest cover and land cover and their changes, especially in the transition ecosystems using remote sensing technology in Jambi Province Regencies.The study areas include Bungo, Tebo, and Tanjung Jabung Barat. The analysis of the patterns were performed using quadrat and nearest neighbor analyses. On the basis of those two approaches, this study shows that the distribution pattern of primary forest, secondary forest, rubber plantation, and oil palm plantation in 1990, 2000, 2011, and 2013 are clumped (clustered) while the distribution pattern of the jungle rubber was dispersed. The pattern of spatial changes from primary forests to secondary forests for the period 1990 - 2000 were clumped, while for the period of 2000 - 2011 were dispersed. The pattern of change from forest to oil palm plantations and rubber plantations were clumped for the period 1990 – 2000 and 2000 – 2011, and the pattern of change from forest to jungle rubber for the period 2000 – 2011 were clumped.

Judul: Deteksi Perubahan Tutupan Hutan dan Lahan Menggunakan Citra ALOS PALSAR Multiwaktu Resolusi 50 Meter di Provinsi Jambi Bagian Timur
Abstrak: Degradation and deforestation in Indonesia is a complex issue that needs to be addressed comprehensively and wisely. Within the period of 2000 - 2012, the national level rate of deforestation is estimated at about 832.126,9 ha / year, while in Jambi Province is approximately 76.522,7 ha/year. Now, the national level deforestation is generally estimated using medium-resolution satellite, such as Landsat, SPOT, ASTER, IRS etc with post-classification comparison approach. For Indonesia, which is located in the tropical region, the use of optical imagery is often constrained due to the high proportion of cloud cover and/or haze during the wet season, and smoke coverage during dry season. The availability of radar imagery such as ALOS PALSAR, JERS-1, Radarsat and ERS-1 that capable to record the earth in all weather conditions as well as capable to penetrate clouds and smoke/haze provide a new prospective in detecting forest and land cover changes. The availability of ALOS PALSAR imageries since 2006/2007 had been provided a good opportunity either for complementing or substituting the optical imagery, especially in the areas of high atmospheric disturbances. Based on the above, this research is aimed to evaluate the ability of 50-meters resolution of ALOS PALSAR imagery for detecting forest and land cover, as well as their changes in eastern part of Jambi Province between 2007 and 2009. The study site includes five regencies in Eastern Part of Jambi Province, namely Tanjung Jabung Barat, Tanjung Jabung Timur, Muaro Jambi, Jambi and Batanghari. Meanwhile, image processing and data analysis was carried out in the Physical Laboratory of Remote Sensing and Geographycal Information System, Laboratory of Forest Resource Inventory Faculty of Forestry IPB. The images used in this reasearch are ALOS PALSAR with HH, HV and synthetic band HH / HV bands recorded on 8 June to 30 November 2007 and from 13 June to 15 October 2009. The softwares used in this research are the Arcview GIS 3.2, ArcGIS 9.3, and Erdas Image 9.1. The classification method used consisted of qualitative and quantitative approaches. In qualitative approach, the classification was performed by visual interpretation on the basis of diagnostic elements of interpretation while in the quantitative approach, classification was done using the supervised classification. The research results show that the Kappa Accuracy of qualitative classification of ALOS PALSAR for 2007 and 2009 are 80% and 82% respectively, while the quantitative approach provides Kappa accuracy of 56% for 2007 and 59% for 2009. The study also found that the largest changes in land cover occured from barren land to plantation forest having area of about 16.866,4 ha. Within 2 years (2007 – 2009) period, the deforestation area is approximately 10.264,3 ha or approximately 5132.15 ha per year, where the largest deforestation occured from forest plantation to oil palm covering area of about 6.928,4 ha or 68% or about 34% per year. Besides, the largest degradation, i.e, from forest plantation to 5 barren land is about 10.195,7 ha or 87% ((or about 34% per year.) By considering the spatial patterns of forest and land cover change between 2007 and 2009, the deforestation and land degradation

Judul: Perancangan Proses Produksi Telur Asin Rendah Kolesterol
Abstrak: Telur asin merupakan produk olahan telur yang digemari masyarakat, tetapi mengandung kolesterol yang melebihi batasan konsumsi harian manusia. Tahap pengolahan, telur asin direndam dalam larutan khusus guna menurunkan kandungan kolesterol di dalam telur. Proses ini melibatkan pengaturan waktu pemeraman, konsentrasi larutan, dan bahan-bahan lainnya untuk mencapai hasil yang diinginkan. Formulasi telur asin yang terpilih yaitu pemeraman selama 12 hari dalam larutan garam 32,5% yang dicampur bawang putih, sereh, dan daun jeruk cincang, perendaman dalam larutan soda 20% selama 4 jam, dan dikukus selama satu jam. Kadar kolesterol sebesar 233,39 mg/100 g pada hari pertama dan mengalami penurunan menjadi 131,61 mg/100 g pada hari kesepuluh., Salted eggs are a popular egg product among the community, but they contain cholesterol that exceeds the daily human consumption limit. In the processing stage, the salted eggs are immersed in a special solution to reduce the cholesterol content inside the eggs. This process involves adjusting the soaking time, solution concentration, and other ingredients to achieve the desired results. The selected salted egg formulation is marinating for 12 days in 32.5% salt solution mixed with garlic, lemongrass, and chopped lime leaves, marinating in 20% soda solution for 4 hours, and steaming for one hour. The cholesterol level was measured at 233.39 mg/100g on the first day and decreased to 131.61 mg/100g on the tenth day.
