Judul: The Effect of the Explosives Quantity to Andesite Production and Ground Vibration at Mount Sudamanik, Cigudeg Subdistrict Bogor Regency.
Abstrak: The andesite rocks of Mount Sudamanik has been exploited by five mining companies that have mining business license (IUP) with a total area of mining business permit area (WIUP) covered to 113 hectares. In 2012, total andesite production of all companies was 3.98 x 106 tons at an average of 332.07 x 103 tons per month. The andesite rocks is produced from at least five times or more blasting every day. The blasting activities will result a ground vibration and noises, it caused to damaging of house construction and disruption of comfort of peoples living around the hill of Mount Sudamanik. The objectives of this study are (1) to determine the effect of explosive quantity to andesite production; (2) to determine the effect of explosives quantity and distance to the ground vibration and sound intensity of blasting to residential communities, (3 ) to assess the community perception to blasting activities. The quantitative approach method with direct measurement at blasting point was applied to assess the effect of explosives quantity, amount and depth of boring holes to andesite production, ground vibration and noise intensity of an explosion. Public perception of ground vibration, noise intensity and anxiety of explosion impact were assessed through questionnaires to 100 respondents who live in the arround of Mount Sudamanik. The results showed that the quantity of explosives usage (X) effect a positive linear respon to the andesite production (Y1) with equation model of Y1 = 4.4X + 66.4. The explosives quantity (X1) and distance (X2) simultaneously effect to the ground vibration level (Y2) as a model equations of The ground vibration due to blasting was below the quality standard of SNI 7571 : 2010. The explosives quantity and distances (r) simultaneously effect to the noise intensity level (TI) of the blasting as a equation model of TI2 = TI1 - 20 log (r2/r1). The noise intensity level of the occurred blasting was below the quality standard SNI 7570 : 2010. Respondent perceptions of the blasting impact indicates that the most feared was fly rock (58%), ground vibration (19%), obstruction of access roads at the blasting schedule (11%), the noise intensity level of the blasting (4%), and no fear of blasting impact (8%).

Judul: Dampak aktivitas pertambangan bahan galian golongan c terhadap kondisi kehidupan masyarakat desa (analisis sosio-ekonomi dan sosio-ekologi masyarakat Desa Cipinang, Kecamatan Rumpin, Kabupaten Bogor, Jawa Barat)
Abstrak: Mining activities is a natural resource mining dredging activities of contained in the soil. This mining activities in its implementation will give positive and negative impact on sosio-economic and sosio-ecological aspect for the local community. The purpose of this study is 1) to explain the sosio-economic impacts of mining activities and 2) to explain the sosio-ecological impacts of mining activities. This research metode uses a quantitative approach supported by the use of qualitative approach. Primary data obtained from the interviews and questionnaires, while secondary data obtained from the documentation and study of literature. The data generated using of cross tabulation and frequency tables and descriptive analysis. The selection of respondents using of cluster sampling techniques to select two different village is Kampung Joglo and Kampung Gunung Cabe. The choice of location is based on mining the large number of industrial plants to see an impact on the agricultural sector. The result of this research showed that in general, in Kampung Joglo and Kampung Gunung Cabe, mining activities gives a negative impacts on socio-economic and sosio-ecological aspects. On sosio-economic aspect are seen in the declining level of the employment in agriculture due to the limited area of agricultural land owned by the local community. Meanwhile, the level of non-agricultural employment opportunities have increased in line with the opening of employment opportunities in the mining sector. The occurens conflicts between local communities with the company caused by the changes of environmental conditions. On sosio-ecological aspect is the occurens changes of the air, a disturbance on the condition of water resources, noise pollution is caused by blasting activities and mineral transport trucks. In addition, still many community members who suffers from respiratory tract such as shortness of breath, caugh, colds and diarrhea.

Judul: Leukemia pada kucing
Abstrak: Leukemia pada kucing adalah suatu penyakit yang sangat patogen, disebabkan oleh sejenis virus. Virus ini dikenal sebagai Feline Leukemia Virus atau FeLV. FeLV ini oleh beberapa ahli dikatakan hanya bersifat ganas pada hewan kucing. Penularannya bisa secara horizontal maupun congenital. Kucing pada semua tingkat umur dapat terserang oleh FeLV ini. Khusus pada bentuk "thymic leukemia", virus ini hanya menyerang anak-anak kucing berumur diba- wah 1 tahun. Kucing-kucing liar atau yang tidak terpeli- hara jarang sekali terinfeksi FeLV. Selain dari serangan virus FeLV itu sendiri, maka penyakit leukemia ini bisa disebabkan oleh beberapa fak- tor yang sudah ada dalam tubuh hewan dan sangat menunjang perkembangan penyakit ini, yaitu antara lain tumor, agen toksik, cedera oleh kecelakaan dan gangguan hemopoiesis. FeLV menyerang sel-sel darah dalam tubuh hewan se- hingga pembentukan darah berjalan tidak normal. Terlihat sel-sel darah yang belum dewasa sudah beredar dalam sir- kulasi darah. Bentuk dan jumlahnya tidak lagi seimbang dalam tubuh hewan kucing tersebut. Gejala klinis antara lain kekurusan, ikterus, anemia, lemah, anoreksia, dyspnoe, sulit menelan, batuk, dan membran mukosa pucat. Selain itu kelenjar pertahanan tubuh juga membengkak, kemudian terjadi hepatomegali, spleenomegali dan pembengkakan pada ginjal. Terbentuk massa tumor pada beberapa tempat. Secara biopsy pada sumsum tulang akan terlihat be- berapa perubahan. Sumsum tulang berwarna merah tua atau abu-abu. Konsistensinya lunak dan terdapat banyak sekali memproduksi sel darah putih. Melalui gambaran darah leukemia ini lebih mudah didiagnosa. Jumlah retikulosit rendah sekali. PCV 8-15%, hemoglobin menurun, sel darah putih (WBC) meningkat, lim- fosit meningkat, Alfaglobulin juga ada peningkatan, dan banyak eosinofil yang belum dewasa beredar dalam darah…dst
