Morphometry Identification of Lice on Male Javan Langur (Trachypithecus Auratus)

A rehabilitation center for Javan Lutung animals in East Java carries out routine checks on rehabilitated animals to prevent diseases that can affect health. Diseases that can infect these endangered animals are not only diseases that are inside the body but also outside the body such as lice infestation. The purpose of this study was to identify the species of louse that attack Javan langurs in an effort to increase information on ectoparasite species in these endemic animals. The sample was obtained from an adult Javan langur, then the sample was preserved by the unstained Slide mounting method. The results were observed using a microscope and body length was measured using the ImageJ software. The results showed that the ectoparasite shape has a flat-dorsoventral body with a total body length of 1.65 mm. From morphometry and morphological characteristics, the samples identified were the male species of Pedicinus ancoratus

Pengaruh Faktor Lingkungan terhadap Produktivitas Telur Ayam Kampung Unggulan Balitbangtan (KUB) Fase Layer

Kecepatan angin, pencahayaan, kelembaban dan suhu merupakan faktor lingkungan yang berpengaruh dalam produksi telur. Ayam KUB atau Ayam Kampung Unggulan Balitbangtan adalah strain ayam petelur baru yang mempunyai kemampuan maksimal dalam berproduksi. Penelitian ini bertujuan untuk melihat seberapa besar pengaruh kecepatan angin, pencahayaan, kelembaban, dan suhu terhadap produktivitas telur Ayam KUB Fase layer pada umur minimal 43 minggu. Data diperoleh dengan desain penelitian cross-sectional melalui pengukuran dan perhitungan terhadap data populasi. Rata-rata faktor lingkungan berupa kecepatan angin, pencahayaan, kelembaban dan suhu adalah secara berurutan yaitu 1.46 m/s, 17.53 lux, 72.11%, dan 27.71oC. Produktivitas telur Ayam KUB Petelur umur 43-46 minggu adalah 66.11%. Seluruh faktor lingkungan secara bersama-sama memberikan pengaruh sebesar 31.4% terhadap produktivitas telur Ayam KUB
