Abstrak: Timber harvesting was an important activity in the forest management, changes of the tree and biomass into a form that can be moved into another place easily so that it can be useful for live and livelihood especially for economics and cultures. That forest opened up area was caused by the trees felling activity, also by skidding road and landing site. The objective of the research was analyze the percentage of forest opened up area by the felling and skidding activities from stump site to the landing site. The data that was used which collected from the year of 2012 and 2013 work plan and also timber harvesting road map. The calculation of forest opened up area was performed from cutting point to the landing site. The plot used in this research is 12 plots with 1 Ha in each plot, the plot ware placed in trees felling to used by low, medium and high felling intensity and landing site area, and also in the skidding road. The forest opened up area calculated by measuring the area that has been opened from the trees felling step until it transported to landing site. This research showed that the forest opened up area caused by forest harvesting activity was about 32.33% with the highest percentage was from trees felling activity was 18.33%, skidding road making was 8.70%, wood skidding activity was 4.60%, and landing site was 0.70%. The timber harvesting technique that applies in that forestry company is a conventional technique.

Judul: Quail Blood Cholesterol Levels (Coturnix coturnix Japonica) On Starters, Growers and Layers phase
Abstrak: Cholesterol is one of fat formation components which is also the main sterol in animal tissues. Therefore its presence are contributing to development and growth of the body. This study aimed to determine blood cholesterol levels and body weight of quail in the starter,grower and layer phases, which were taken at the age of 18 days, 25 days and 330 days. The quail (Coturnix coturnix Japonica) used were ten tails of the starter phase, grower phase and layer phase. Blood cholesterol levels were measured using a NESCO MultiCheck 3 in 1 tool and body weight was calculated using a digital scale. Cholesterol levels decreased from the starter (158,40 mg/dL) phase to the grower phase (123,00 mg/dL) and increased again in the layer phase (219,6 mg/dL). The highest blood cholesterol value was obtained in the layer phase. The body weight over time continued to experience an increase and the increase in body weight from the starter to the layer phase was not followed by an increase in cholesterol levels. Cholesterol levels are used according to their physiological needs, Kolesterol merupakan salah satu komponen pembentuk lemak yang juga merupakan sterol utama dalam jaringan hewan, oleh karena itu kehadirannya memberikan kontribusi untuk perkembangan dan pertumbuhan tubuh. Penelitian ini bertujuan untuk mengetahui kadar kolesterol darah dan bobot badan burung puyuh pada fase starter, grower dan layer, yang diambil pada umur 18 hari, 25 hari dan 330 hari. Burung puyuh (Coturnix coturnix Japonica) yang digunakan sebanyak sepuluh ekor pada masing-masing fase starter, fase grower dan fase layer. Kadar kolesterol darah diukur menggunakan alat NESCO MultiCheck 3 in 1 dan berat badan dihitung menggunakan timbangan digital. Kadar kolesterol menurun dari fase starter (158,40 mg/dL) ke fase grower(123,00 mg/dL) dan meningkat lagi pada fase layer(219,6 mg/dL). Nilai kolesterol darah tertinggi diperoleh pada fase layer. Bobot badan dari waktu ke waktu terus mengalami peningkatan yang dan peningkatan bobot badan dari fase starter ke fase layer tidak diikuti dengan peningkatan kadar kolesterol yang artinya bobot badan tidak berpengaruh pada kadar kolesterol burung puyuh. Kadar kolesterol digunakan sesuai dengan kebutuhan fisiologisnya
