Judul: Analisis Ekonomi Dampak Alih Fungsi Lahan Pertanian Terhadap Ketahanan Pangan di Kabupaten Karawang Jawa Barat (Studi Kasus Desa Tanjungpura Kecamatan Karawang Barat)
Abstrak: During 2002-2012, the number of converted land in Karawang has reached 10 027 ha. The result of this study showed that the pattern of land conversion in Karawang was triggered by the high number of population’s growth. The rate of land conversion in Karawang during 2002-2012 are fluctuated, with average point of -0.71%. The land institutional that was analyzed from Rencana Tata Ruang Wilayah (RTRW) stated that Karawang will be converted into urban and industrial area based on Peraturan Daerah Undang-Undang No. 2 Year 2013. The factors that affect land conversion externally are the number on industries and the proportion between agricultural land to total area. The factors that affect land conversion internally are farm costs and the proportion between farm income to total income. The average number of farmer’s income after the land conversion was reduced by Rp.2 599 900. The impact to production was the loss of rice production in the past ten years, which is 130 547.02 tons, or Rp 344 054 232 300 worth. Based on prediction, the land area and the conversion impact to food security will cause 6 796 tons of rice shortage on 2026. If rice consumption per capita was reduced by 1.5% every year, then Karawang won’t be able to provide the needs of rice in 2031 with 6 438 tons shortage. The implication’s policy to overcome rice field conversion could be done from several aspects such as social aspect, economy aspects, and environment aspect. It could be done by implementing the land quota, compensate farmers, and agricultural intensification.

Judul: Analisis perubahan penggunaan lahan dalam kaitannya dengan keinginan petani untuk mempertahankan lahan pangannya di Kabupaten Karawang
Abstrak: Construction activities and population growth led to increased demand for land, while the availability of land basically unchanged. Conversion of agricultural land into other uses that are not controlled will cause a negative impact in the economic, social and environmental aspects. To overcome these negative impacts requires enormous cost. This study aims to identify the dinamic of land use change in Karawang Regency in 2001, 2006 and 2012, to analyse factors that influence land use change in Karawang, to know determinants of land sustainability of food at farmers' income levels and to identify spatial distribution of the concentration of rice area in Karawang. Data analysis used spatial analysis, binary logistic regression analysis and the G statistic analysis. Analysis of land use change results in 2001-2012 showed that the area of wetland, forest, dryland agriculture and plantations decreased 10,046.8 ha (5.22%), 2,307.8 ha (1.20%), 391.6 ha (0.20%) and 136.1 ha (0.07%), respectively . On the other hand, undeveloped land and bush increased 11,021.8 ha (5.73%), and 1,860.3 ha (0.97%). Extensive water bodies and ponds remain the same in the amount of 263.1 ha (0.14%) and 18,748.4 ha (9.75%) over the period of analysis. In general, factors that increase the chances of changes in land use in Karawang Regency in the period of 2001-2012 are the distance to the center of town, population growth and the growth of the economy. In contrast, growth variables diversity of social facilities, the establishment of regional spatial plans are strictly instrumental decrease the chances of land use change. Determinants significant sustainability of food land are tenure (rental property), the area of land owned, and the percentage contribution of agriculture to meet the needs. In 2001 there were four significant sub-districts have a large and assamble plot of land that Cibuaya, Pedes, Jayakerta and Cilebar. In 2006 and 2012 convergence with large plot only in two Kecamatan Pedes and Cibuaya. Meanwhile in the three periods of the same small plot consistently spread in the area of South Karawang includes, Pangkalan, Ciampel, Telukjambe Timur, Tegalwaru, and Klari

Judul: Light Microscope Study of ConnectiveTissue in The Spleen of Common Rousette Bat (Rousettus amplexicaudatus)
Abstrak: The spleen is the largest lymphoid organ. As a secondary lymphoid organ, in addition to its immune function, the spleen also has functions as blood filtration, storage, and hematopoiesis. The spleen has different morphologies between species that support different physiological functions, one of which is the difference in the structure of the capsule and trabeculae. Capsule and trabeculae of the spleen generally consist of connective tissue and smooth muscle. The thickness of smooth muscle composed together with connective tissue in the capsule and trabecula determines the function of the spleen that is divided spleen into three storage, defense, and intermediate. Bats are the reservoir of various zoonotic diseases. Bats are thought to have unique immune systems compared to other mammals but the characteristics of its immune organs such as the spleen have never been studied before. This study was conducted to examine the characteristics of capsulae and trabecula of the Common Rousette (Rousettus amplexicaudatus).
