Tujuan penelitian ini adalah mendeskripsikan mengenai karakteristik sarang Tarsius. Diharapkan dengan deskripsi ini dapat dibuat suatu modifikasi sarang Tarsius. Manfaat yang diharapkan adalah memberikan informasi mengenai karakteristik sarang Tarsius di Cagar Alam Tangkoko dan sebagai referensi pengetahuan dalam bidang konservasi satwa langkah dan endemik. Penelitian ini dilaksanakan di Cagar Alam Tangkoko Batuputih Bitung Sulawesi Utara selama 61 hari dengan menggunakan 10 sampel sarang Tarsius. Penelitian ini menggunakan metode observasi. Variabel penelitian ini adalah Jenis vegetasi, bentuk sarang, lingkaran pohon dan ketinggian sarang dari permukaan tanah, suhu dan kelembaban sarang dan variabel penunjang antara lain adalah ketinggian sarang dari permukaan laut (mdpl) dan vegetasi sekitar sarang. Berdasarkan hasil penelitian jenis vegetasi, ditemukan bahwa semuanya adalah pohon jenis Ficus sp dengan rataan lingkaran pohon adalah 8,169 m. Bentuk sarang Tarsius tidak beraturan dan lubang sarang umumnya berbentuk bulat lonjong dan berbentuk persegi dengan ketinggian sarang antara 1,5 m sampai 13 m. Suhu dalam sarang Tarsius antara 20,97°C sampai 23,92°C dan kelembaban sarang Tarsius antara 77,3% sampai 81,4%.  Rataan ketinggian sarang dari permukaan laut adalah 53 mdpl. Vegetasi di sekitar sarang Tarsius ditemukan 24 jenis vegetasi yang di dominasi oleh vegetasi jenis Leea indica dari famili Leeaceae.

DAILY BEHAVIOUR OF SULAWESI BEAR CUSCUS (Ailurops ursinus) IN TANGKOKO BATU ANGUS NATURE RESERVE. This study aimed to describe dailly behaviour of Sulawesi Bear Cuscus (Ailurops ursinus) in Tangkoko Batu Angus Nature Reserve. This reseach is expected to provide information about inactive, foraging, intake, groom and social behavior of  Ailurops ursinus as primary behavior variables of the animal daily activities. The usie of vegetation during animal daily activities were introducted in this research as a secondary variable. This research used obsevation as research  method and instantinous animal sampling technique. This method observed Ailurops ursinus behavior three times per day . Each single observe was done in 60 minutes with 60 seconds time interval. Every single observe was replicated 14 times. The result of this research showed that the daily behaviour of Ailurops ursinus was dominated by inactive behaviour with 56.86 percents consisted of 30.5 minutes were spent in the morning, 42.6 minutes at noon and 29.2 minutes in the afternoon. Intake behaviour took times of 26.98 percents consisted of 17.2 minutes were spent in the morning, 8 minutes at noon and 23.3 minutes in the afternoon. The foraging behaviour took times of 15.11 percents consisted of 11.7 minutes were spent in the morning, 8.7 minutes at noon and 6.6 minutes in the afternoon. Groom activity spent times of 0.98% consisted of 0.5 minutes spent  in the morning, 0.5 minutes at noon and 0.7 minutes in the afternoon. Social behaviour took spent time of  0.03% of total daily behaviour spent only at noon.   Keywords : Daily behaviour, Sulawesi Bear Cuscus (Ailurops ursinus), Tangkoko Batu Angus Nature Reserve

SENSORICAL QUALITY AND PHYSICAL PROPERTIES OF CHICKEN NUGGETS WHICH IS ADDED PURPLE ROAD UBI FLOUR (Ipomoea batatas L). This study aims to determine the benefits of using purple sweet potato flour (Ipomoea batatas L) on the sensory quality and physical properties of chicken nuggets. The research was carried out in 3 stages, namely (1) making purple sweet potato flour, (2) making chicken nugets with the addition of purple sweet potato flour, (3) testing chicken nuggets including sensory quality testing using 35 untrained panelists to measure the level of acceptance of aroma, color, texture and taste, physical properties test to determine water binding power and cooking losses. This research was conducted experimentally using a completely randomized design with 4 additional treatments of purple sweet potato flour, namely P1 = 10 g, P2 = 20 g, P3 = 30 g and P4 = 40 g, each treatment was repeated as many as 35 (panelists) for the test. sensory quality and 5 replications for physical characteristics test. Data from the observation of sensory quality test, physical properties were tabulated and analyzed by analysis of variance (Ansira) and if there were significant differences between treatments, it was continued with Duncan's multiple test (DMRT). The results of the research with analysis of variance showed that the addition of 10, 20, 30 and 40 grams of purple sweet potato had a very significant effect (P <0.01) on color, texture, water-binding capacity and cooking loss but had no significant effect. (P> 0.05) on aroma and taste. The results of Duncan's multiple further test showed that the P4 treatment of 40 g of purple sweet potato gave the best results on color, texture, water binding power and cooking loss. Based on the results and discussion, it can be concluded that the addition of 40 g of purple sweet potato flour in the manufacture of chicken nuggets provides good sensory quality and physical properties.Keywords: Chicken nuggets, purple sweet potato flour, sensory quality, physical properties

STUDY ON SLAUGHTER ACTIVITY OF BABIRUSA (Babyrousa babirussa celebensis DENIGER) AS THE ENDEMIC FAUNA IN NORTH SULAWESI AT THE SEVERAL TRADITIONAL MARKETS IN MINAHASA REGENCY. Babirusa (Babyrousa babyrussa celebensis D.) is categorized as a valuable germinal plasma and included into protected fauna since sixty years along a go. Therefore, this animal was noted into endangered animals. However, the hunting activities of the local community are occurring in the remote area of Minahasa as indicated by availability of meat trading of this animal. The objective of this study was to evaluate the slaughter activities dealing with meat trading of this endemic fauna on several traditional markets in Minahasa regency. Study was conducted by survey method focusing on hunters, traders and consumers buying meat of this animal on several traditional markets in Minahasa regency. Results showed that meat of Babirusa (Babyrousa babyrussa celebensis D.) were still traded and found on several traditional markets in Minahasa regency indicated by hunter existences of 0 to 25 percents, meat sellers of 8.33 to 50 percents, and fixed meat consumers of 58.33 to 100 percents of this animal. These cases were spreading on the traditional markets around districts of Tondano, Remboken, Kawangkoan, Langowan and Tanawangko. As the conclusion that slaughters and trading activities of the protected Babirusa (Babyrousa babyrussa celebensis D.) were existing recently in the remote areas of Minahasa Regency.Key words: Babirusa (Babyrousa babyrussa celebensis D.), endemic,  traditional market.

This study aims to study the internal quality of chicken eggs MB 402 feed with different protein and energy balance. A total of 80 MB 402 chicken aged 38 weeks with the treatment given (P1 15% protein, 2800 kkcal/kg energy metabolisme), (P2: 16%  protein, 2800 kcal/kg energy metabolisme), (P3: 17% protein, 2700 kcal/kg energy metabolisme) dan (P4: 18%, protein 2700 kcal/kg energy metabolisme). The design used is a complete random design (RAL) with 4 treatment 5 replications in each treatment there were 4 MB 402 laying hens. Research variabeles include : egg yolk index, egg yolk colour, and egg white index. The results showed that the protein and energy balance in the ration had no real effect (P > 0,05) to the color of the yolk, the index of the index of the yolk, and theo0 index of the egg whites. Conclusions the use of protein and energy balance in ration with level 15% protein and 2800 kcal/kg energy metabolise. Keywords: laying hens MB 402, Protein and energy balance, Egg quality
