Judul: Aktivitas Makan, Kuantitas dan Kualitas Pakan Pada Bekantan (Nasalis larvatus) yang Diberi Berbagai Jenis Pakan di Taman Safari Indonesia
Abstrak: Proboscis monkeys (Nasalis larvatus) are primate that live in groups on trees and consume leaves. The consumption of leaves is done by proboscis monkeys in their feeding activities. The feeding activities of proboscis monkeys relates to the fulfillment of their daily energy. The energy is needed for the continuity of the group existence. The feeding activities of proboscis monkeys have several activities. They are observing, taking, checking, processing, biting, chewing, ingesting, pulling out the feed from their mouth and disposing the feed. The quantity of food that consumed determines the sufficience amount of nutrient needed. This study aimed to assess the feeding activities, the feed quantity and the quality of proboscis monkeys (N. larvatus) which are given many kinds of food items in Taman Safari Indonesia. The data collection for the feeding activities was performed using ad libitum and focal animal sampling methods. The feeding activities were observed for 46 days since June until July 2009, 6 hours a day with total of 276 hours observations. The percentages of the eating activities of Boki (the adult male), Ayu and Chintya (the adult females) and Kia, Nakula, Pretty (the infants) were 34,15%, 29,92%, 30,91%, 11,13%, 7,69%, and 7,36% respectively. The chewing and pulling out the feed from their mouth on adult male, adult females and infants were the largest and the smallest percentage of the feeding activities (57,14%, 60,31%, 63,71%) and (1,55%, 2,47%, 1,95%). While, the adult male revealed the greatest percentage of regurgitation (57,06%). Proboscis monkeys have good palatability in type of bean. The result of the study revealed that the monkeys have sufficient dry matter and protein consumption (48,82 g/BB/h, 89 g/BB/h and 5,76 g/BB/h, 10,50 g/BB/h), but less for fat and energy (1,06 g/BB/h, 2 g/BB/h and 115,88 kkal/BB/h, 211 kkal/BB/h), while nutrient recommended.

Abstrak: Silvered leaf monkeys (Trachypithecus cristatus) are primate that live in groups on trees and consume leaves. The feeding activities of silvered leaf monkey relates to the fulfillment of their dialy energy. The energy is needed for the continuity of the group existence. The feeding activities of silvered leaf monkeys have several activities. They are observing, taking, sorting, processing, biting, chewing, ingesting, pulling out their mouth, and disposing the feed. The study aimed to identify the feeding activities, kind and composition of feed, nutrient consumption and energy of silvered leaf monkeys (Trachypithecus cristatus) in Schmutzer Primate Center (PPS), Ragunan Zoo, Jakarta. Data is collected from June to September 2011 with total of 480 hours observations. The data collection for the feeding activities was performed using ad libitum and focal animal sampling methods. Based on the observations, there were three types of activities with the highest frequency. Such as resting, locomotion, and feeding activity at 44.87%, 40.89%, and 38.70%. Respectively the chewing feed activities on infants were the higest of the feeding activities (36.90%). Silvered leaf monkeys in Schmutzer Primate Center (PPS) have good palatability in type of lamtoro leaves (Leucaena glauca). The result of the study revealed that adult and infants monkeys have sufficient dry matter and protein consumption (40,5 g/BW/d, 8 g/BW/d and 63 g/BW/d, 12,5 g/BW/d), but less for fat and energy (2,37 g/BW/d, 23,87 kcal/BW/d and 3,75 g/BW/d, 37 kcal/BW/d), while nutrient recommendation

Judul: Penerapan teknik watermarking untuk penandaan hak cipta pada peta vektor dengan format DXF
Abstrak: Drawing Interchange Format (DXF) is one of the general file in the field of the vector image commonly used for making maps. The DXF format is a tagged data representation of all the information contained in an AutoCAD drawing (DWG) file. Tagged data means that each data element in the watermark is preceded by an integer number called the group code. The study was carried out because there is still no tools of labeling the copyright on digital mapping using DXF file. This study aims to generate an application for copyright labeling on vector map with DXF format that can be applied to any types of spatial objects in the map. The technique used is changing the code inside the vector image. The insertion of the watermark is done by utilizing ENTITIES section by multiplying objects for sets of binary values. The results showed that the image after the watermarking insertion process is the same as the original vector image. Embedded watermark is resistant to rotation and scaling, however it has the possibility of one-third to be broken in the attack on specific object. This study has successfully implemented watermarking technique for copyright labeling on the vector map with DXF format.
