Abstract

The Chlorophyll vegetation is able to absorb CO2 from the atmosphere through photosynthesis, as well as the bamboo talang does. The purpose of this research was to account the carbon content in each section of bamboo talang (Schizostachyum brachycladum kurz.) and to determine the best allometric model to estimate the potential of carbon reserves in the bamboo talang in harvested-over areas in people forest bamboo, Village Pertumbukan. The research was carried out in two stages, namely the first stage was to take the data in the field and the second stage was to analyze the carbon content in each section of bamboo talang in the laboratory. The results showed that the best allometric model for estimating biomass and carbon mass of bamboo talang was W = 44.614-14.047D+1.26D2 and C = 20.159-6.390D+0.585D2. Biomass and carbon mass off bamboo talang in People Forest Bamboo Pertumbukan Village, District Wampu, Langkat were 5.85 ton/ha and 2.82 ton C/ha, respectively. Keywords: Bambu talang (Schizostachyum brachycladum Kurz)., community forest, carbon stock, allometric models

Abstract

This research aimed to assess the feasibility of herb agroforestry utilization in the community forest of Gerbosari Village, Kulon Progo. This research measured NPV (Net Present Value), Net B/C (Net Benefit-Cost Ratio), IRR (Internal Rate of Return), and AEV (Annual Equivalent Value) as the financial feasibility criteria. A stratified sampling method was employed in which sixty farmers were classified into three strata based on the size of their lands. Based on the financial feasibility analysis, in stratum I, the values of the criteria measured were NPV of IDR15,757,980.56/ha/25 years, Net B/C of 1.62, IRR of 22.12%, and AEV of IDR1,296,647.20/year. In stratum II, the values of criteria measured were NPV of IDR14,255,408.39/ha/25 years, Net B/C of 1.76, IRR of 23.78%, and AEV of IDR1,173,007.88/year. Finally, in stratum III, the criteria measured were NPV of IDR19,444,703.86/ha/25 years, Net B/C of 2.21, IRR of 32%, and AEV of IDR1,600,009.64/year. The results suggest that herb agroforestry plays an important role in farmers' livelihood particularly as a source of income in both the short and long terms. The herb agroforestry utilization contributes positively to the economy of Gerbosari Village, Kulon Progo District.
