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 alih fungsi lahan pertanian terhadap kemandirian pangan di Kabipaten Subang (studi kasus : Desa Belendung, Kecamatan Cibogo)
Abstrak: Increasing of population and economy growth in Indonesia, particularly in industrial sector, leads to the demand increasing of land. Whereas the land supply is not able to fulfill the demand. This caused the problem of decreasing in agricultural land, especially rice field which converted for public housing and industrial development. There was a fluctuative rate of land conversion in Subang district. In the periode of 2003-2012 the total rate of conversion was -0,57 percent or the average rate of conversion was -0,057 percent. There are the factors that affected land conversion on macro scale in Subang district such as public housing and number of industry. There are the factors that affected land convertion on micro scale in Subang district such as land area and farm revenue. Besides that, land price was significant affected of farmer decisions for selling or converting them land. Farmers total revenue have been decreased as to be as Rp 1.090.762/month. Besides farmer revenue, occurring of land conversion decreased rice production. Rice production lost by 231.241 ton or Rp 1.107.460.400.000. The simulation result of food reliance with assumption productivity and consumption rate are constant showed that rice production in Subang district can’t supply their needs on 2100 with the number of short coming is 2.773 ton. There was various aspect of policy implication which could overcome land conversion such as social aspects, economy aspects, and environmental aspects.

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.
