Judul: Analysis of Peanut Plant Suitability in West Java Province Based on Agroclimate Zoning and Climex 4.0 Model
Abstrak: Tanaman kacang tanah merupakan salah satu komoditas penting di Indonesia. Analisis kesesuaian lahan sangat dibutuhkan untuk menentukan wilayah potensi pengembangan tanaman kacang tanah. Penelitian ini bertujuan mengevaluasi kesesuaian lahan untuk tanaman kacang tanah di Provinsi Jawa Barat serta menganalisis hubungan nilai ecoclimatic index untuk tanaman kacang tanah pada daerah yang sesuai dan tidak sesuai. Kesesuaian lahan dianalisis berdasarkan faktor iklim (curah hujan dan suhu udara), dan faktor tanah (tekstur tanah dan kemiringan). Faktor iklim dan tanah yang di overlay menghasilkan 4 kelas kesesuaian yaitu S1 (sangat sesuai), S2 (cukup sesuai), S3 (sesuai marjinal), dan N (tidak sesuai). Overlay kelas agroklimat dengan kelas penggunaan lahan menghasilkan wilayah yang potensial untuk pengembangan tanaman kacang tanah. Tanaman kacang tanah cukup sesuai ditanam di Provinsi Jawa Barat, hal ini ditandai dengan peta potensi pengembangan didominasi oleh kelas kesesuaian S2 dan S3. Kelas S2 merupakan kelas yang paling dominan yang dapat dikonversi yaitu 2.075.623 ha atau 55% dari luasan Provinsi Jawa Barat. Kabupaten Tasikmalaya memiliki luasan kesesuaian S1 terluas sehingga direkomendasikan menjadi area pengembangan tanaman kacang tanah sebesar 51.227,6 ha atau 18% dari total luasan Kabupaten Tasikmalaya. Nilai ecoclimatic index dari pemodelan menggunakan Climex 4.0 memiliki nilai korelasi R-Square sebesar 0,63. Nilai ecoclimatic index memiliki korelasi positif dengan analisis kesesuaian lahan secara manual menggunakan Arcmap 10.8., Groundnut is one of the most important commodities in Indonesia. Land suitability analysis is needed to determine the potential areas for peanut crop development. This study aims to evaluate the suitability of land for peanut in West Java Province and analyze the relationship of ecoclimatic index values for peanut plants in suitable and unsuitable areas. Land suitability was analyzed based on climate factors (rainfall and air temperature), and soil factors (soil texture and slope). Climate and soil factors were overlaid to produce 4 suitability classes, namely S1 (highly suitable), S2 (moderately suitable), S3 (marginally suitable), and N (unsuitable). Overlaying agroclimate class with land use class results in potential areas for peanut crop development. Groundnut plants are quite suitable to be planted in West Java Province, this is indicated by the map of potential development dominated by suitability classes S2 and S3. Class S2 is the most dominant class that can be converted, which is 2,075,623 ha or 55% of the area of West Java Province. Tasikmalaya Regency has the largest area of S1 suitability so that it is recommended to be a peanut crop development area of 51,227.6 ha or 18% of the total area of Tasikmalaya Regency. The ecoclimatic index value from modeling using Climex 4.0 has an R-Square correlation value of 0.63. The ecoclimatic index value has a positive correlation with manual land suitability analysis using Arcmap 10.8.

Judul: Analisis Kesesuaian Lahan Tanaman Kedelai berdasarkan Aspek Agroklimat (Studi Kasus Kabupaten Cianjur dan Kabupaten Subang)
Abstrak: Soybean is one of the crops that need to be developed. Other than through intensification, development of soybean plants can be use with the extensification or expansion. Determination of land suitable for development of soybean plants can be done by focusing on agro-climate, the climate and soil factorsThe purpose of this study was to analyze the level of agro-climatic suitability of soybean plant in Cianjur and Subang. The weighted overlay process method was used in this study. From the analysis and mapping showed quite suitable area (S2) in Cianjur was 1396.8 km2 or about 50%, suitable marginal region (S3) was 1389.0 km2 or about 49%, and the area was not suitable (N) an area of 9.6 km2 or about 1% of the cianjurarea. As in Subang, an area highly suitable (S1) was 1181.6 km2 or about 55%, quite suitable (S2) 809.0 km2 or about 38%, and suitable marginal region (S3) was 151.6 km2, or about 7% of Subang wide, and there were no areas that are not suitable (N).

Judul: Pengaruh Infeksi Haemoproteus columbae (Kruse, 1890) Pada Burung Merpati Dan Cara Penanggulangannya
Abstrak: Haemoproteus columbae merupakan paras it yang menyerang sel-sel darah merah burung rnerpati. Siklus hidupnya kompleks dan dapat dibagi menjadi dua yaitu siklus hidup asexual terjadi delam tubuh burung merpati dan siklus hidup sexual terjadi dalam tubuh lalat dari famili Hippoboscidae sebagai vektor. Stadium yang nampak dalam peredaran darah perifer hanyalah garoetosit yang dapat dibedakan menjadi dua yaitu gametosit jantan (mikrogametosit) dan gametosit betina (makrogametosit).
