Judul: Evaluasi Persamaan Infiltrasi Kostiakov dan Philip secara Empirik untuk Tanah Regosol Coklat Kekelabuan
Abstrak: Infiltrasi penting diketahui karena dapat digunakan untuk memprediksi besarnya air hujan yang berpotensi mempengaruhi besarnya limpasan permukaan, banjir, erosi, ketersediaan air untuk tanaman. air tanah dan ketersediaall aliran sungai selama musim kemarau. Namun, karena persamaan kapasitas infiltrasi yang ada sekarang ini hanya berlaku pada suatu waktu dan kondisi tanah tertentu yang dilakukan pada waktu pengukuran, maka perlu dilakukan pengumpulan data dari berbagai kondisi tanah. Dari berbagai data tersebut kemudian ditentukan suatu persamaan infiltrasi yang berlaku secara umum Dalam penulisan ini, persamaan infiltrasi yang dipakai adalah Persamaan infiltrasi Kostiakov dan Philip.

Judul: Evaluasi persamaan infiltrasi dari kostiakov dan philip di Lapang
Abstrak: Infiltrasi penting diketahui karena merupakan salah komponen yang penting dalam hidrologi. Air meningkatkan kelembaban tanah dan atau menjadi satu infiltrasi akan kelebihannya akan mengisi air bawah tanah aliran bawah tanah. Peningkatan jumlah air yang dapat diinfiltrasikan oleh suatu jenis tanah, akan mengurangi jumlah air yang menjadi limpasan permukaan dan mengurangi erosi. Dari persamaan infiltrasi akan didapatkan laju maksimum infiltrasi dari sutau jenis tanah, sehingga besarnya air curah hujan yang mempunyai potensi untuk melimpas setelah mencapai permukaan tanah dapat diperhitungkan. Penelitian ini bertujuan mengevaluasi persamaan infiltrasi, mengevaluasi penentuan penggunaan titik/data, mengevaluasi hubungan antara kadar air awal tanah dengan koefisien-koefisien dari persamaan Kostiakov dan Philip dengan proses pengepasan (fitting process) di lapang. Penelitian dilakukan pada petak kecil berukuran ...

Judul: Ukuran organ reproduksi dan kualitas sperma mencit (Mus musculus) yang mendapat bahan pakan kemangi (Ocimum basilicum L.) kering
Abstrak: Kemangi (basil: Ocimrrm basilicrrm L.) is \itell known as a traditional medicine plant wich is used to increase reproduction ability. It has been discovered that basil has a group of beneficial chemical compound to induce the bcdy respon, especially to the reproductive orsan. This research was conducted to study the pharmacological effect of basil to mice (Mrcs mrrsarlrrs) sperm quality and its reproductive organ. This research were conducted at Animal Breeding and Genetic Laboratory, Faculty of Animal Science, Bogor Agricultural University, from May up to August 2005. Experiments were done for seven week feeding trials, a total of 30 weaning mice were allotted to three treatment levels. The treatments were done by giving dried basil at level 0; 2.5; and 5.0% from diet.Data were collected 50% from each treatment level (5 mice each). Observation variables were 1) measurements of reproductive organ such as width and length of scrotal; width, length, and weight of testis and penis; length of epididymis, and vasdeferens; and 2) sperm quality such as sperm concentration, viability, motility, abnormality, and mass movement. Data were analyzed by completely randomized designed one way pattern with 10 repetitions, and continued with Tukey Test. It was discovered that the treatments did not give significant effect both to sperm quality and reproductive organ measurement except to the scrotal and epididymis. It was found that scrotal length significantly increased (P<0.01) in 2.5% level as compared with 0% level, but there was no significant differences in 5.0% level as compared both with 0 and 2.5% level. Scrotal width increased (PCO.05) in 2.5% level as compared both with 0 and 5.0% level, but there was no significant increased in 5.0% level as compared with 0% level. Also found that epididymis length increased (P<O.OS) in 2.5% level as compared in 0% level, but there was no significant differences in 5.0% level as compared both with 0 and 2.5% level.
