PENDUGAAN ETAT LUAS ETAT VOLUME DAN ETAT TEBANG PADA HUTAN PINUS ( Pinus merkusii ) DI BKPH NGANTANG KPH MALANG

The main products of the enterprise grade pine for latex production, at the end of recycled pine can be calculated to estimated results of the volume of standing stock, other than that there is no research about etat fell at the end of the cycle of the pine in BKPH Ngantang, so it can background investigators to examine etat Ngantang BKPH pine forest has a 50 year rotation. Research conducted in the pine forests Ngantang BKPH KPH Malang to determine the volume estimates. This study was conducted in August and September 2019, methodes field collecting be made plots of 20 x 20 meters, diameter measurements, height, then the data is calculated using the formula approach Von Mantel. Primary data collection to data on the number of stands in 2018 as well as studies related literature. etat total volume at BKPH Ngantang 564.127 m³/year and total comprehensive etat BKPH Ngantang has 3.4 hectare/year. Results of the calculations for the annual cutting etat Ngantang RPH has 424.461 m³/year, RPH Kasembon 503.336 m³/year and RPH Sekar 489.918 m³/year. There were several plots with pine resin results doesn’t fill the targets latex. The total amount of latex that must be namely 32.963 kg/year, while resin obtained 29.579 kg/year. Factors influencing that labor, weather and the age of the stand
