Judul: Analisis Spasial Konversi Lahan Sawah Menuju Ketahanan Beras Domestik di Kecamatan Ciampea Kabupaten Bogor
Abstrak: Bogor regency has high of population growth, economy, and infrastructure so that the need for residential land is also high. Land conversion to settlements is irreversible (not-return) and has long-term impact. Conversion of paddy fields to settlements has impact to food security. The aim of this research is to: analyze the distibution of paddy fields based on slope and road distance, analyze socioeconomic of paddy fields farmer and determine the adequacy of domestic rice and the potential threat of domestic rice security due to. The techniques used are the analysis of images to find out characteristics of land cover/use and see the distribution of paddy fields by slope and distance of the road, determine the socioeconomic characteristics of paddy field farmers through interviews, logistic regression to determine factors affecting land conversion, calculation of the balance of the rice, and overlay to find out rice security threat. The type of land use in sub-district Ciampea dominated by dryland, mixed farming, and rice fields. The existence of paddy fields and farming are dominant at southern regions and a small portion is at the northern area. The result of regression analysis logistics binary obtained that the variable of broad rice fields ( X5 ) has the most influential factor.The equation is (Y) =-49.769 + 8.193X5. Based on the level of rice security threat, 9 villages belong to categorized of medium and 4 villages belong to high category, while based on level of potential rice fields conversion 8 villages belong to categorize of low, 2 villages belong to medium category and 3 villages belong to high category. The balance of rice in the sub-district Ciampea is deficit, because almost entire village belong to deficit status and only one village has surplus status. This condition has threaten the availability of rice while the level of potential rice fields conversion dominanted by low category and has failed to fullfil domestic food security in sub-district Ciampea, as it’s dominant villages belong to medium category.

Judul: Analisis Dampak Ekonomi dari Alih Fungsi Lahan Pertanian ke Non Pertanian Terhadap Ketahanan Pangan di Kabupaten Bogor.
Abstrak: Population growth in Bogor Regency increasing year by year. Along with population growth, there is also increasing food needs that related to agricultural sector. Currently, changes to the transformation of the economic development towards the direction of industrial development and manufacturing. In addition, increasing population growth requires residential development. This case, indicated agricultural land conversion. The aims of the study were to know the rate of agricultural land conversion in Bogor Regency, to find out the factors which affect, and to analyze the economic effect and an appropriate policy in the control of agricultural land conversion. Agricultural land conversion in Bogor Regency has been fluctuated year by year. The average of land conversion in Bogor Regency was 0,01 percent per year or 7,1 hectar per year. On this study showed that the increasing density of society and the paddy productivity were affected to the agricultural land conversion. Meanwhile, the agricultural land conversion will affect change of the farmer‟s total income before and after land conversion amount of Rp 52.176 in month. The average income before the conversion amount of Rp 1.931.157 and the average income amount of Rp 2.878,96. Beside the farmer‟s total income, the agricultural land conversion also caused the reducing of paddy production. The average loss of paddy production per hectare converted land was 2.878,96 tons per year, while the average loss production value was Rp 7.771.656.534,60 in paddy forms and Rp 8.518.512.570,00 in rice forms. The estimation result of food security in Bogor Regency showed that rice production has not adequated the needs of rice in 2002- 2011.

Judul: Aplikasi Serat Sutra Laba-laba Nephila sp. Sebagai Material Benang Jahit Bedah Pada Vena Jugularis Kelinci
Abstrak: Penelitian ini bertujuan mengevaluasi serat sutra Nephila sp. pada bedah vena jugularis, dan menilai derajat reaksi inflamasi yang ditimbulkannya. Koleksi serat sutra Nephila sp. dilakukan dengan menarik serat sutra Nephila sp. dari kelenjar ampullata kemudian digulung dengan aluminium foil. Beberapa lapis serat sutra Nephila sp. disatukan secara septis dan diikatkan dengan jarum jahit. Tiga ekor kelinci New Zealand White digunakan dalam penelitian ini. Semua kelinci mendapat perlakuan penyayatan pada vena jugularis yang kemudian dijahit dengan serat sutra Nephila sp. Kemudian melakukan euthanasia pada ketiga kelinci dan diamati pada minggu 1, 3 and 5 pasca operasi. Berdasarkan pengamatan perubahan patologi anatomi dan histopatologi pada sampel vena jugularis dari ketiga kelinci, jahitan menggunakan serat sutra Nephila sp. pada ketiga kelinci tidak memberikan efek penekanan pada vena jugularis, yaitu tidak menyebabkan penyempitan lumen vena jugularis aliran darah masih tetap normal (tidak menyebabkan pembendungan). Pengamatan secara histopatologi, pada kelinci 1 minggu pascaoperasi, tampak bahwa bentuk dan struktur vena jugularis yang terdiri dari dinding vena jugularis (tunika intima, tunika media dan tunika advensia) tidak dapat teramati dengan baik. Pada kelinci 3 minggu pascaoperasi ditemukan adanya pembekuan darah. Pada kelinci 5 minggu pascaoperasi tampak bahwa luka bekas sayatan yang dijahit dengan serat sutra Nephila sp. sudah terlihat sembuh dengan baik dan kelihatan seperti tidak pernah mengalami sayatan (operasi). Berdasarkan hal tersebut di atas disimpulkan bahwa serat sutra Nephila sp. adalah biokompatilitas di mana berfungsi sebagai antimikroba, biodegradasi di antara 3 hingga 5 minggu pasca operasi dan menimbulkan sistem kebal imun yang minimal. Dengan itu, serat sutra Nephila sp. dapat digunakan sebagai material benang jahit bedah khususnya pada operasi pembuluh darah.
