Physical Environment, Population Parameter, and Morphometric Records Morphometric of the Monitor Lizard in Papua

Many studies have explored animals without providing its physical environment, whereas, this information can provide broad understanding for the importance of ecological components. This study tried to combine some studies on how importance the ecological means on the density and population as well as morphometric of the monitor lizards. Data was analysed using SPSS version 18.0 and presented descriptively using tables and graphics. Results show that density and population had association with wide areas of islands and distances from mainland. Morphometric as well had association with carrying capacity and richness of feeding

Nutritive Value and the Quality of Ensiled Napier Grass (Pennisetum Purpureum Schum.) and Banana (Musa Acuminata) Peelings

This paper aimed to evaluate the nutritive value and the quality of ensiled Napier grass (Pennisetum purpureum Schum) and banana (Musa acuminate) peelings. Different levels of banana peeling and Napier grass were used in this study. The levels of Napier grass and banana peeling compared as treatments with four replications were as follows: 100% Napier Grass (NG), 75% (NG) + 25% Banana Peeling (BP), 50%NG + 50%BP, 25%NG + 75% BP and 100%BP. Napier grass and banana peeling were mixed based on the percentage combination as treatments, weighed and placed into empty jam bottle with weights ranging from 64.4 grams to 509.2 grams as a simulated laboratory silo. Samples were stored in eight weeks at the Dairy Training Research Institute. Proximate analyses were done at Animal Nutrition Laboratory Institute of Animal Science while ADF, NDF, IVDMD, and IVOMD were done at the Animal Nutrition Division Laboratory at Dairy Training and Research Institute, UP Los Baños. Physically, the color of silage were light yellow with a little greenish color for 100% napier grass, light to moderately yellow for the three combinations of napier and banana peel and yellow for 100% banana peel. Texture ranged from dry and coarse for napier grass, relatively dry for the combinations and moderately wet for the banana peel. The napier grass had a slightly acidic smell, the combinations had slightly sweet, acidic smell while the 100% banana peel had a sweeter, acidic smell. Likewise, pH before ensiling had ranged from 5.7 (25%NG + 75%BP) to 7.5 ( 100% BP) while after ensiling the pH changed from 4.575 ( 100% napier grass) to 5.75 ( 100% banana peel ). There were significant differences on DM, Moisture, CP, EE, CF, and Ash before ensiling. Similar trend was observed after ensiling except the ash content of all the treatments. ADF and NDF did not show significant variations in all treatments. IVDMD and IVOMD before ensiling varied significantly, but after ensiling only IVDMD of the treatments differed significantly. In terms of physical attributes, nutritive value and digestibility, banana peel can be used as silage material. All treatments generated comparable acceptability when fed to the animal. It is suggested that further study, specifically in vivo trial, will be conducted to validate the feeding and nutritional value of banana peel as alternative silage for ruminants

Herpetofauna pada Habitat Hutan Batu Gamping di Manokwari, Papua Barat; Spesies, Keragaman, Kekayaan dan Populasi

The research was conducted in the Maruni limestone forest habitat. The observation plots were carried out at an altitude of 35 masl to> 212 masl. Observations were made 2 times every day (day and night). The method of calculating diversity is done using the Shannon-Wieners Index and the species population is calculated using the Alikodra formula. 11 species were found that belong to the Varanidae, Boidae, Gekkonidae, Ranidae, and Hylidae families. The diversity of wildlife in the Maruni limestone location follows the altitude of the habitat. Reptiles do not differ according to height. The most common types are in the class of lizards, monitor lizards, and frogs. The types of herpetofauna that can be found are carnivores and are not protected. This type of monitor lizard can be found in abundance in low areas to an altitude of> 200 meters above sea level. Meanwhile, monitor lizards can be found in wet forests and near water sources. Similar to lizards, frogs inhabit wet or watery areas. The diversity of wildlife species in limestone habitats in each class of Reptiles is 18%. The population of herpetofauna species found varied between 25-1200 individuals
