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.

Judul: Performans Organ Reproduksi Mencit (Mus musculus) yang Diberi Pakan Mengandung Protein Sel Tunggal
Abstrak: Reproduksi ternak ditentukan oleh kemampuannya untuk menghasilkan selsel kelamin yang berkualitas dan melakukan aktivitas reproduksi agar dapat menghasilkan individu baru dalam waktu yang singkat. Untuk menghasilkan sel-sel kelamin yang baik dibutuhkan dukungan organ-organ kelamin yang dapat berfungsi dengan normal. Sel-sel dalam organ reproduksi tersebut membutuhkan masukan nutrisi yang berkualitas. Dengan demikian kualitas pakan turut juga mempengaruhi performa organ-organ reproduksi. Sumber protein alternatif yang dapat digunakan adalah Protein Sel Tunggal (PST) . Penggunaan PST selain menguntungkan secara ekonomis dan nutrisi, ternyata banyak penelitian menunjukkan pengaruh terhadap organ-organ vital. Pengaruh yang sama mungkin dapat terjadi pada organ-organ reproduksi. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan PST sebagai substitusi Meat and Bone Meal (MBM) pada ransum terhadap performan organorgan reproduksi. Taraf substitusi yang diujikan yaitu 0%, 1,5%, 3%, 4,5% dan 6% terhadap MBM. Hewan percobaan yang digunakan adalah mencit sejumlah 50 ekor (jantan dan betina) yang akan dibagi dalam lima perlakuan dan lima ulangan dengan diberi pakan dan minum ad libitum. Masing-masing ulangan terdiri atas dua ekor. Mencit dipelihara selama dua bulan dan pengamatan dilakukan di akhir penelitian. Peubah yang diukur meliputi bobot, panjang dan diameter testis, panjang vas deferens, jumlah sperma mencit jantan serta bobot dan panjang organ reproduksi betina. Selain itu dilakukan uji histopatologi terhadap organ reproduksi jantan maupun betina.

Judul: : Persamaan Tunggal sebagai Representasi Kurva Komposit
Abstrak: A mathematical method is introduced to represent a composite curve based on an extension of analytic geometry. The representation is given either with a single equation or with two equations, in the case of parametric representation. This method permits the representation of composite curves in similar manner to the conventional representation of non-composite curves. Some mathematical tools, including Heaviside unit step function and periodizer function, are used in the establishment of a single equation. In this paper, regular equations of regular and irregular polygon, as well as composite curves of two dimensions, are implemented using a computer algebraic system, Mathematica.
