Judul: Ketahanan sperma ayam hutan hijau (Gallus varius) untuk membuahi sel telur ayam domestika  (Gallus gallus var. domesticus)varius)  dan gambaran sterilitas hasil persilangannya
Abstrak: Ayam Hutan Hijau (Gallus varius) merupakan satwa asli Indonesia, karena dalam penyebarannya hanya terdapat di pulau Jawa, Madura, Kangean, Bawean, Bali, Lombok, Sumba, Flores, Alor, dan pulau-pulau kecil disekitarnya. Bentuk eksterior ayam Hutan ini indah dan suara cukup memikat.。 Satwa ini disukai dan sering diburu orang, sehingga keberadaannya semakin punah. menurun dan terancam Persilangan antara ayam Hutan Hijau jantan dengan ayam Domestika (Gallus gallus var. domesticus) disebut ayam Bekisar. Ayam hibrid ini yang jantan merupakan unggas kesayangan dan kesenangan yang mempunyai nilai komoditas yang tinggi. Unggas ini merupakan identitas Propinsi Jawa Timur. satwa Inseminasi Buatan sangat efektif untuk menolong persilangan yang tidak bisa atau sulit untuk kawin secara alami (Toelihere, 1985). Mc. Faquhar, Lake (1964) dan Orgasewara, Huang (1963) dalam Watson (1978) menyatakan bahwa persilangan antar genus dapat terjadi dengan ini. Bahr dan Bakst dalam Hafez (1987) menyatakan bahwa dalam saluran kelamin unggas betina sperma mengalami seleksi pada "Utero-vaginal junction". Sperma yang dapat bebas dari seleksi ini kemudian memasuki lipatan mukosa dan saluran kelenjar dibelakang Infundibulum. Persilangan antar dua spesies yang berbeda biasanya menghasilkan keturunan (F1) yang mandul, menurut teori evolusi kemandulan ini merupakan usaha alam untuk meles- tarikan spesies agar tidak muncul spesies baru (Hanson, 1981 dalam Evalinda, 1989). ...

Judul: Studi Banding Kualitas Antara Ayam Hutan Hijau (Gallus Varius) Dan Ayam Lokal (Gallus Domesticus)
Abstrak: A comparative study of sperm quality between the Green Jungle fowl (Gallus varius) and the Lokal fowl (Gallus domesticus) has been conducted. This experiment was conducted to identify the sperm quality of Green Jungle fowls (Gallus varius) and the Domestic fowls (Gallus domesticus). Semen was collected from 5 Green Jungle fowls and 5 Domestic fowls by massage and evaluated macroscopic and microscopically. Semen evaluation includes volume of ejaculation, smell, color, viscosity, pH, concentration, mass movement, percentage of motility, life and death and normality of the sperm cells. Semen was collected and evaluated individually with 5 replications weekly. The results showed that the semen quality of the Green Jungle fowl (Gallus varius) was significantly different (p<0,05) in volume, concentration and motility. However no differences were found in percentage of living and normality. Ejaculate volume of the Green Jungle fowl was 0,02±0,004 ml with sperm concentration of (62,5 ± 21)x 107 cells/ml and percentage ofliving 84,5 ± 3,2%. Ejaculate volume the Domestic fowl was 0,16 ± 0,02 ml with sperm concentration (176,8 ± 49,4) x 107 cells/ml and percentage of living 85,1 ± 4,4 %. Sperm motility of the Green Jungle fowls was 68,1 ± 2,9 % with slight mass movement (+). Sperm motility of the Domestic fowls was 71,9 ± 1,1 % and mass movement of (+) while pH from both the Green Jungle fowl and the Domestic fowl were similar. Percentage of normality of spermatozoa of the Green Jungle fowl was 80,7±3,1% and that of the Domestic fowl was 86,2±3,6 %. Semen of the Green Jungle fowl is like semen of the Domestic fowl were similar in color, smell, and viscosity. It could be concluded that semen quality of domestic fowls in some aspects is superior as compared to those of the green jungle fowl.

Judul: Penyelesaian Numerik Persamaan Schrödinger untuk Molekul BaO dan SrO Menggunakan Model Potensial Morse
Abstrak: Morse potential is a potential model used to describe the behavior of a molecular vibration between atoms. This study aimed to obtain the value of the dissociation energy, the energy eigenvalues of each energy level, and describe the shape of the wave function of the molecule BaO and SrO on the vibrational state. Dissociation energy is calculated by adding the experimental dissociation energy and the ground state energy eigenvalues. Calculating the energy eigenvalues of the energy levels 0 to 4 using shooting method integrated with Numerov and Runge-Kutta method. Energy eigenvalues of each levels that calculated numerically having accuracy of 100% compared with the calculated analytically. The profil of wave functions accurately show the corresponding states and their normalized wavefunctions.
