Judul: Observasi Lama Siklus Dan Periode Estrus pada kuda (Equus caballus) di detasemen kavaleri berkuda (Denkavkud) Parongpong Lembang-Jawa Barat
Abstrak: The success of reproductive activity in horses is closely related to the estrous cycle and estrus period. This study reports the estrous cycle, estrus period as well as estrus behavior in the Detasemen Kavaleri Berkuda with the environmental temperature range between 23 to 27oC (day) and 17 to 20oC (night). The length of the estrous cycle was 19.21±3.67 days, with estrus itself lasting 4.95±0.5 days. The behavior arising during estrus was decreasing appetite, squealing with stallion, occasional urinating and aversion of the vulvae labia (winking), secreting of white to cream mucus at the vulva, mare do not refusing when approached by stallion or come to the stallion and squatting, went to stud by itself and give the back part or its rump. The vulva in estrus mare appear to be larger than non estrus mare, the vulva looks wet and dried mucus left on a part of the vulva. Other characteristic were the high frequent of urination during in the stable that makes the cage looks wetter than non estrus mare and estrus mare always raising the tail in a relatively long time.

Judul: Penentuan Estrus Melalui Gambaran Sitologi Ulas Vagina dan Hubungannya dengan Gejala Klinis Estrus pada Kambing Peranakan Etawah
Abstrak: The aims of this study was to determine estrous time of Etawah cross breed (ECB) goats through vaginal cytology profile and its correlation with clinical signs of estrous following prostaglandin administration and during the natural estrous cycle. Fifteen does were each administered with 7.5 mg prostaglandin to get a synchronized estrous response and onset of estrous. The does showing estrous response were also observed during the next estrous cycle (natural estrous cycle). Vaginal cytology profile and the correlation with clinical signs of estrous were observed when standing heat sign were visible. The result showed that the average estrous cycle was 19.7 days (18-23 days) with the duration of estrus period was 54 hours (24-72 hours). The response of estrous after prostaglandin administration was 60% of ECB with the onset of estrus was 78.6 hours (72-84 hours) and the duration of estrus was 44 hours (12-60 hours). Clinical signs of estrous were standing when ridden and vulva sign (swollen and redden vulva, vaginal discharge) generally showed moderate intensity (++). The presence of large number of superficial cells (45-53%) and small number of parabasal cells (5-8%) could be used to determine of estrous, however, it couldn’t be used alone to determine of optimal mating time. Determination of optimal mating time should be based on a combination observation of standing heat sign, clinical signs of estrus, and vaginal cytologic profile.

Judul: Penggunaan Limbah Plastik Sebagai Komponen Bahan Baku Papan Partikel
Abstrak: Kurangnya ketersediaan kayu bulat jika dibandingkan dengan kebutuhannya serta besarnya volume limbah industri pengolahan kayu mendorong perkembangan teknologi pembuatan produk kayu yang dapat mengatasi kedua masalah tersebut di atas. Di antara produk-produk kayu yang dapat memecahkan masalah tersebut adalah papan partikel. Saat ini papan partikel telah banyak diproduksi sebagai bahan baku bangunan maupun untuk perabot rumah tangga yang telah dipakai oleh masyarakat luas. Pengembangan teknologi pembuatannya tetap diperlukan untuk mengatasi kelemahan-kelemahan papan partikel di dalam pemakaiannya. Salah satu kelemahan papan partikel yang cukup berarti adalah sifat pengembangan tebalnya. Di sisi lain, limbab plastik yang menumpuk di muka bumi semakin banyak seiring dengan meningkatnya industri bahan baku dan barang jadi plastik. Sedangkan bahan ini tidak dapat diuraikan oleh mikroorganisme pengurai. Penumpukan limbah plastik tentunya akan dapat merusak lingkungan bila tidak segera diatasi.
