Judul: Potention of Carbon for Acasia Forest
Abstrak: Forest has a function that includes social, economic, ecological, and environmentally important enough for human life. In fact, efforts to maintain the stability of forest function would be difficult to do especially for countries that are developing, where the economic function of forests is more dominant. Utilization of forest that are not offset by maintenance and repair efforts will result in forest destruction and human losses. In this context, the destruction of forests is one of the causes of global climate change. Solutions that might be done now is to maintain the remaining forest area based on the function of forests as carbon storage. This study aims to determine the potential for carbon uptake in acacia at BKPH Parungpanjang KPH Bogor. In this research, application of sampling method followed by a destructive method using a tree sample of each age class. In addition, validation testing based on sample trees conducted to test the equality of the research sites. Estimation of potential carbon uptake in each age class using the equations that have been validated. The results showed that carbon uptake in each age class is different, namely in age class 2, 3, 4, 5, 6, 7, and 8 respectively of 2,923 tons ha-1, 17,624 tons ha-1, 23,987 tons ha-1, 49,581 tons ha-1, 20,782 tons ha-1, 15,326 tons ha-1, and 56,047 tons ha-1. Increased expectations of potential carbon uptake seen with increasing age class in acacia stands, except for age class 6 and 7, it is caused by a diseased.

Judul: Potential Carbon Storage of Acacia and Puspa Mixed Stand at KHDTK Haurbentes, Bogor.
Abstrak: Hutan memiliki peranan penting dalam mengendalikan pemanasan global. Hutan menyerap CO2 dan menyimpannya sebagai biomassa tumbuhan melalui proses fotosintesis. Penelitian ini bertujuan untuk menghitung potensi biomassa dan simpanan karbon pada tegakan campuran akasia dan puspa di KHDTK Haurbentes, Kabupaten Bogor, Jawa Barat. Penelitian dilakukan dengan membuat petak contoh berukuran 20 x 20 m. Pengukuran biomassa pancang, tiang, dan pohon dilakukan dengan metode non destruktif sedangkan pengukuran biomassa serasah dan tumbuhan bawah menggunakan metode destruktif. Analisis contoh serasah dan tumbuhan bawah untuk memperoleh nilai berat kering tanur dan karbon tersimpan dilakukan di Laboratorium Pengaruh Hutan, Fakultas Kehutanan dan Lingkungan IPB. Hasil penelitian menunjukkan bahwa potensi biomassa dan simpanan karbon pada tegakan campuran akasia dan puspa di KHDTK Haurbentes sebesar 31.70 ton/ha dan 15.62 ton C/ha. Hasil pendugaan potensi simpanan karbon berbanding lurus dengan potensi biomassa., Forest has an important role in controlling global warming. Forest absorbs CO2 and stores it as plant biomass through the process of photosynthesis. The purpose of this research is to calculate biomass and carbon storage potential of acacia and puspa mixed stand at KHDTK Haurbentes, Bogor. The research was conducted by making sample plots measuring 20 x 20 meters. The measurement of the biomass of saplings, poles, and trees was carried out using a non-destructive method, while the measurement of the biomass of litter and understorey using a destructive method. The analysis of litter and understorey samples to obtain the dry weight of the kiln and stored carbon is carry out at Pengaruh Hutan Laboratory, Faculty of Forestry and Enviroment, IPB. The result of this research showed that potential for biomass and carbon storage of acacia and puspa mixed stand at KHDTK Haurbentes are 31.70 ton/ha and 15.62 ton/ha. The estimation of carbon storage was directly proportional to biomass potential.
