Abstrak: Obesity is a primary predisposition for diseases such as metabolic syndrome (such as insulin resistance, blood lipid abnormality, and hypertension), type 2 diabetes, and cardiovascular disease. The effort to overcome obesity is needed by understanding develop of obesity. Therefore, it is urgent to carry out preclinical trials by using an obese animal model. The objective of this research was to study the high energy feed with animal fat and carbohydrate to produce obese cynomolgus monkeys (Macaca fascicularis). Animals used in this study were 15 adult males divided equally into three treatment groups; 1) receiving feed A consist of beef tallow without egg yolk (energy 4,207 cal/g, fat 19.62%, and starch 60.34%); 2) receiving feed B consist of beef tallow and egg yolk, (energy 4,207 cal/g, fat 19.62%, and starch 60.34%) 3) receiving feed C, monkey chow as control (energy 4,330 cal/g, EE 5.55%, and NFE 51.38%). Measurement were carried out every four weeks for body weight gain, sitting height gain, hip diameter, abdominal thickness, body mass index, feed and nutrient consumption, and feed digestibility. Results showed that there was significant (p<0.05) body weight gain in week- 4 and 8. Based on the average difference test, it was known that feed B was resulting the highest (p<0.05) body gain compared to feed A and C. For the body measurement, the monkeys with feed B were bigger (p<0.05) than feed A and C. Therefore, it was considered as obese in terms of body mass index. Protein digestibility in feed A and B was lower (p<0.05) compared to C. However, digestibility in dry matter, fat, starch and energy were about 90%, meaning that the rations were considered good in making obese monkey. The feed formula containing tallow and egg yolk could increase body weight resulting in a positive correlation toward body measurement and body mass index.

Judul: Performa Obesitas  Monyet Ekor Panjang (Macaca fascicularis) yang Diberi Pakan Berenergi  Tinggi
Abstrak: The aim of this research was to found obesity performances of long-tailed macaques (Macaca fascicularis) which fed with high energy diet. Two groups of five adult males (average body weight 4-6 kg) were treated by three types of high energy diets (A treatment, B treatment and C treatment). Body measurements which observed were crown-rump length; the circumferences of calf (of leg), thigh, hip, waist, chest, arm, and head; thicks of meta-tarsale and meta-carpale; skin fold thickness of arm, back, and stomach; body weight and body mass index (BMI). Data were analyzed by ANOVA, with nested design. The result showed that obesity performances of long-tailed macaques which fed with high energy diet were significantly (P<0.01) for circumferences of hip, waist and chest; skin fold thickness of back and stomach; body weight and body mass index. Body mass index of long-tailed macaques on treatment high energy diet with raw material tallow and yolks indicated became pre- obese with base on Asia people BMI standard with BMI’s average 24.85.

Judul: Formulasi TSP (Traveling Salesman Problem) menggunakan ILP (Integer Linear Programming)
Abstrak: TSP is a journey of salesman f?om his origin town (place) to visit n-cities (places) only at once, then return to his origin town (place) with a minimum total distance. Its purpose is to minimize the operating expense that is released by the company. Vehicle route at TSP in the form of a Hamiltonian cycle, that is closed path containing all nodes at the graph which representing a network walk. Its problem is to determine a journey route which is feasible (possibly can be passed by) in such a way the vehicle travelled distance passed the route is minimum.
