Judul: Infiltration rate in various land use types in Ciambulawung watershed, Lebakpicung village, Lebak-Banten.
Abstrak: Water is one of important resources to all living entities. Nonetheless, available water decreases by time. Water has been known having a close relation to soil. One was important factor on water availability is the infiltration. In this study, the relationship of land use and soil physical properties to infiltration rate ware studied. To achive the goal, infiltration was measured using double ring infiltrometer. The research took place in TNGHS area and the soil physics laboratory, Balittan, Bogor from February until July 2011. Samples were determined using stratified radom sampling method, based on land use and soil physical properties. Meanwhile, statistical analysis involved correlation analysis, and regression, especially stepwise regression. The result showed that soil infiltration rate ranged from moderate up to rapid. It was found that land use types tend to have a relationship with infiltration rate, as well as soil physical properties. Based on field measurements, infiltration rate in the forest area was about 51,5 cm/hours (very rapid), while in sengon plantation was 15 cm/ hours (rapid). It appears that mixed garden achieved fairly rapid infiltration (5 cm/ hours), which was quite similar to agricultural fields (2,75 cm/ hours; middle). Statistical analysis showed that variables tend to have multicollinearity. Land use presented by NDVI, did not correlate to flow infiltration. This means that NDVI value was less robust to estimate land use parameters. Meanwhile, analyses of soil characteristics, indicated that only rapid pore drainage, bulk dencity, particle dencity, and pemeability statistically influenced infiltration rate.

Abstrak: Land use is an important aspect in maintaining ecosystem sustainability, particularly in the watershed ecosystem. Land use determines to physical, chemical, and biological characteristics of soil. These soil characteristics influence to the growth of plants and the performances of water infiltration into soil. Infiltration is an essential part of the hydrological cycle that has an important role water availability in the soil. Infiltration process have an important role to the distribution of rainfall and control to runoff, flood, erosion and ground water storage and finally will determines the availability of river discharge in dry season. The aims of this research is to assess the performance of soil infiltration in various land use in Ciujung watershed. The study was conducted on three land use types that included plantative forest (HT), dense mixed garden (KCR), and less-dense mixed garden (KCTR). The field observation was done by using the Double Ring infiltrometer method, while the the analysis of the physical and chemical and other soil characteristics were done in the Laboratory of Soil and Water Conservation, Department of Soil Science and Land Resources, Faculty of Agriculture. The results of this research showed that the infiltration rate is strongly influenced by land use. Infiltration rate is the highest and most stable on HT land use, followed by KCR and KCTR. Constant infiltration rate at HT and KCR is belonging to quickly class, while at KCTR is relatively moderate to fast. The magnitude of the rate constant infiltration in HT (23.4 cm h-1) is higher than KCR (13.2 cm h-1) and KCTR (6.0 cm h-1). The high rate infiltration of the soil on the land use of HT support it able to accommodate as much water (6.45 dm3) that higher than at KCR (3,66 dm3) and at KCTR (1.52 dm3). Infiltration rate is influenced by pores with large size (PDSC), while the volume of water infiltration is more influenced by the total porosity of the soil. Besides it is influenced by land use, soil infiltration in the study area is also determined by the physical and chemical characteristic of the soil organic matter, bulk density, total porosity, aggregate stability, macro pores, very fast drainage pore (PDSC), and soil texture.

Judul: Durasi dan beberapa aspek fisiologi pemakaian anestetikum xylazine dan ketamin untuk ovariohisterektomi pada kucing lokal
Abstrak: Salah satu dari hewan kesayangan yang banyak diminati orang diantaranya adalah kucing lokal, karena selain mudah pemeliharaannya juga memiliki daya adaptasi yang cukup baik. Kucing lokal mempunyai kemampuan reproduksi yang cukup tinggi sehingga ditemukan dalam jumlah yang sangat banyak dan mudah diperoleh di Indonesia. Untuk mengantisipasi meningkatnya populasi kucing lokal di Indonesia salah satu usaha yang dilakukan dalam bidang Kedokteran Hewan diantaranya adalah ovariohisterektomi. Ovariohisterektomi adalah suatu tindakan operasi untuk menghilangkan ovarium dan uterus dengan tujuan menghilangkan estrus dan kebuntingan (Shutleworth and Smythe 1960). Langkah awal dari tindakan operasi adalah dilakukannya anestesia. Tindakan anestesia tidak merupakan hal yang asing lagi. Anestesia memegang peranan penting dalam dunia Kedokteran Hewan khususnya hal-hal yang berkaitan dengan tindakan operasi karena anestesia dapat menghilangkan rasa sakit dan menimbulkan relaksasi, Untuk melakukan operasi besar (operasi mayor) seperti ovariohisterektomi perlu dilakukan anestesia umum, selain itu pemberian preanestetikum juga dipertimbangkan dengan tujuan mengurangi gangguan fisiologik yang timbul seperti muntah selama atau sesudah anestesia, bradikardia dan hipersalivasi (Handoko 1999; Hall 1978). Untuk mencapai anestesia yang ideal, Handoko (1999) menyatakan bahwa kombinasi beberapa bahan kimia mungkin akan saling berpotensiasi atau efek salah satu bahan kimia dapat menutupi pengaruh bahan kimia yang lain. Penelitian dilakukan di Laboratorium Bedah Veteriner Jurusan Klinik Veteriner, Fakultas Kedokteran Hewan Institut Pertanian Bogor. Penelitian ini bertujuan untuk mengetahui durasi terpanjang dari ke-empat perlakuan dengan perubahan aspek fisiologi yang tidak berat. Hewan percobaan yang digunakan adalah kucing betina lokal dewasa sebanyak 32 ekor umur sekitar satu sampai tiga tahun, berat badan antara dua sampai tiga kg dengan status present baik. Hewan percobaan dikelompokkan menjadi empat kelompok perlakuan, masing-masing terdiri dari delapan ekor sebagai berikut: (1) pemberian xylazine dosis 2 mg/kg berat badan (bb), 15 menit kemudian diberikan ketamin dosis 10 mg/kg bb; (2) kombinasi xylazine dosis 2 mg/kg bb dan ketamin dosis 10 mg/kg bb; (3) pemberian xylazine dosis 2 mg/kg bb, 15 menit kemudian diberikan ketamin 15 mg/kg bb; (4) kombinasi xylazine dosis 2 mg/kg bb dan ketamin dosis 15 mg/kg bb…dst
