Judul: Konversi Lahan Pertanian dan Perubahan Taraf Hidup Rumahtangga Petani: Kasus Pembangunan Perumahan X di Kampung Cibeureum Sunting dan Kampung Pabuaran, Kelurahan Mulyaharja, Kecamatan Bogor Selatan, Kota Bogor, Provinsi Jawa Barat
Abstrak: Conversion of agricultural land and changes in household living standards of farmers: a case of Housing Development by PT. X in Kampung Cibeureum Sunting and Kampung Pabuaran, Kelurahan Mulyaharja, Kecamatan Bogor Selatan, Kota Bogor, West Java. The objectives of this study were: (1) identified household living standards of farmers after the land conversion, (2) analyzed the factors associated with land conversion rates by farmers. The research applied a quantitative approach which supported by qualitative information. The quantitative data were collected by using survey method on 35 farmers household . The results of this study showed that after the conversion of land, household living standard of farmers increased, especially for lower-class farmers households. Internal factors and external factors affect different for each of the farmers. In this study, the internal factors that affected the rate of land conversion is dependence on the land. Dependence of land only affect the conversion rate at the lower class farmers. External factors also have different effect on each among farmers. In this study, external factors which affected the conversion rate is the influence of neighborss, the influence of neighbors only affected the conversion rate at the lower-class farmers. Key words: Conversion, land, farmers

Judul: Dampak Konversi Lahan Terhadap Keberlanjutan Ekologi. Studi Kasus: Kelurahan Mulyaharja, Kecamatan Bogor Selatan, Kota Bogor, Provinsi Jawa Barat.
Abstrak: This study has three objectives: 1) to identify the phenomena and factors that cause land conversion, 2) to examine the impact of land conversion in terms of sociological, economic, and political aspects, 3) to examine the impact of land conversion of ecological aspects .This study was conducted in the village Mulyaharja. It is an area of land conversion, where almost the entire area of Mulyaharja has switched its functions into a settlement area (real estate). Previously the area was productive agricultural land. The case of agricultural land conversion in Mulyaharja was caused by the farmers’ decision to sell their land and such decision was promoted by such factors as economic, social, and policies. The effects of land conversion involve a number of aspects. For example, its sociological impacts include the gap between indigenous people and immigrants as well as lifestyle changes introduced by the immigrants. The economic impacts include changes in land tenure, productivity and income levels of the community. The political impact can be seen from the many companies that are committed to investment of funds in one or more assets for several periods in the future. The conversion of agricultural land to settlement area has greatly negative impact on the ecology. The ecological already apparent now shows the damage to the environment at an alarming stage because of the big large opportunity for the rural communities of Mulyaharja to move and open up land on the higher ground. Now, there should be fundamental changes in the paradigm of development in relation with nature.

Judul: Aplikasi Nano Kitosan Sebagai Pengawet Alami Fillet Nila Merah (Oreochromis Sp.) Selama Penyimpanan Suhu Chilling
Abstrak: Nano kitosan diketahui berpotensi dalam memperpanjang masa simpan produk perikanan karena sifatnya yang tidak beracun, biodegradable, dan memiliki aktivitas antibakteri. Penelitian ini bertujuan menentukan karakteristik nano kitosan dan membandingkan penggunaan nano kitosan dengan formalin dalam mengawetkan fillet ikan nila merah pada penyimpanan suhu chilling. Nano kitosan dibuat dengan metode gelasi ionik dan dikarakterisasi melalui analisis Particle Size Analyzer, mikroskop elektronik payaran, dan Fourier Transform Infrared. Fillet direndam dalam larutan formalin (F), akuades (T), dan nano kitosan (L) selama 5 menit dan nano kitosan 10 menit (S). Fillet disimpan pada suhu 4±1 oC dan dianalisis total mikroba aerob, Total Volatile Base, dan pH pada hari ke-0, 2, 4, 6, 8, 10, dan 12. Karakteristik nano kitosan yang dihasilkan berukuran 512,58 nm dengan morfologi berbentuk bulat dan derajat deasetilasi sebesar 79,49%. Perendaman dengan nano kitosan selama 5 menit merupakan perlakuan terbaik untuk pengawetan fillet. Nilai total mikroba aerob, TVB, dan pH fillet S, L, dan F belum melewati batas aman konsumsi (<5 log cfu/g, <20 mg N/100 g, dan <7) hingga penyimpanan hari ke-12 dan tidak berbeda nyata satu sama lain (p>0,05), sehingga nano kitosan dapat dijadikan pengawet alami fillet nila merah dan dapat menggantikan formalin bila dilihat dari parameter total mikroba aerob, TVB, dan pH.
