Judul: Effectivity of various doses of glycerol in tris extender and equilibration time on frozen semen quality of crossbred etawah bucks
Abstrak: The objectives of this research were to determine the optimum dose of glycerol in Tris extender and equilibration time in maintaining frozen semen quality of crossbred Etawah bucks. This research consist of two sections: (i) evaluation of various glycerol doses (5, 6 and 7 percent) and (ii) evaluation of various equilibration time (1, 2, 3 and 4 hours), both in tris extender. Results of the first experiment indicated that the mean percentage of post thawing motility, live, intact plasma membrane and intact acrosomal cap of spermatozoa in 6% glycerol (52.60%, 65.03%, 45.63% and 47.54% respectively)were significantly higher (P< 0.05) than in 5% (44.31%, 52.00%, 37.60% and 37.00%) and 7% glycerol (45.28%, 52.10%, 37.97% and 37.14%).

Abstrak: Reproduction of goats in Indonesia mostly managed by natural mating, while the Artificial Insemination (AI) has been limited. The success rate of AI in goats has been low because of some factors, one of those has been identified as the low quality of extender. Tris Egg Yolk (TEY) and AndroMed® have been widely used for extenders of frozen semen in goats. Effect of Tris Soya (TS) that have lesitin nabati and studies to describe the profiles of each extenders to the sperm quality have been quite limited. The aim of this study was to compare TEY, AndroMed® and TS extenders on sperm motility and viability before and after freezing of goats semen. Semen was collected from three sexually mature Etawah Crossbreed goats twice a week, each semen sample was divided into three tubes to be mixed with TEY, AndroMed® or TS before those got frozen. Sperm motility and viability were evaluated macroscopically before freezing and microscopically before and after freezing. The result of this study revealed that TEY and AndroMed® gave higher sperm motiliy (68.52±0.64% and 68.71±1.95%) than TS (37.03±4.25%). The viability of sperm was also higher in TEY and AndroMed® (73.45±1.52% and 73.94±1.31%) compared TS (46.76±4.76%). It was concluded that TEY and AndroMed® were better extenders to protect goats sperm compared TS.

Judul: Fungsi keluarga bagi anak jalanan di perkotaan : Kasus anak-anak jalanan di sekolah binaan YNDN, Pasar Kebayoran Lama, Jakarta Selatan
Abstrak: Fenomena yang menyebabkan munculnya anak jalanan berkaitan dengan ekonomi keluarga. Pendapatan orangtua yang rendah sehinggan tidak mampu lagi memenuhi kebutuhan keluarga, memaksa anak untuk ikut bekerja. Apalagi pada masa krisis seperti sekarang ini, kepala kelaurga (ayah) mengerahkan seluruh anggota keluarga untuk bekerja mempertahankan hidupnya. Tidak sedikit anak-anak yang menjadi korban ekploitasi orangtua. Sehingga mengakibatkan mereka keluar rumah untuk mencari ketenangan dan pergaulan yang baru. Anak-anak bekerja di tempat-tempat umum (pasar, jalanan dan lain-lain), mereka sering menghadapi masalah seperti kriminalitas, obat-obat terlarang, preman, aparat pemerintah dan sebagainya. Maka peran LSM sangat dibutuhkan bagi anak- anak jalanan dalam memberikan perhatian tentang keberadaan mereka. Dengan demikian yang menjadi permasalahan yaitu bagaimanakah kondisi anak jalanan di perkotaan, dan sejauh mana pengaruh peran keluarga bagi anak jalanan, dan sebaliknya?, selain itu bagaimanakah peran LSM dalam mempengaruhi anak jalanan?
