Abstract

ABSTRACTCarbondioxide (CO2) Absorption by Trees in "Mekar Sari" Fruit Garden, Bogor, in Relationto Green house Gases Mitigation. Biological diversity can make a significant contribution toreducing the build-up of greenhouse gases in the atmosphere. A biological diverse tropicalforest with a diverse plant species typically stores 50 times more carbon per unit area comparedto monoculture plantation replacing it. Thus, the trees in forests have an essential role in thefunctioning of the terrestrial biosphere, especially in the carbon cycle. Yet wild tree photosynthesesare poorly studied than crop photosynthesis for several reasons: the large number ofspecies; difficulty in measuring photosynthesis of entire trees or of forest stands. This researchaims to assess the contribution of biological diversity in CO2 absorption by analyzing thephysiological characteristics (photosynthesis, transpiration, stomatal conductance, leaf chlorophyllcontent) of tree species in "Mekar Sari" fruit garden, Bogor. The results will provideinformation on carbon sequestration of some tree species suitable for revegetation. Variance inCO2 assimilation rate is large among trees species. The results showed that there was a widerange of variation of CO2 assimilation rate between tree species. The overall CO2 assimilationrate ranged 2.33 - 13.42 ?molm-2s-1. The highest was Matoa (13.42 molm-2s-1 ) , followed byKacapi (12.50 ?molm-2s-1), Durian (11.00 ?molm-2s-1) and Nangka (11.00 ?molm-2s-1). Transpirationrate was recorded between 4.29 - 9.50 molm-2s-1. The rate of CO2 assimilation wasaffected by incident radiation and thus the quantum leaf (Q leaf) as well as leaf chlorophyllcontent. Correlation between CO2 assimilation and Q leaf under certain environmental conditionwas considerably high. Variance in stomatal conductance and transpiration rate variedamong tree species and were related to light intensity.Key words: Photosynthesis, CO2 absorption, trees

Abstract

The Family Hope Program (PKH) is a conditional cash transfer program given to poor families in Indonesia. PKH in the long term is expected to be able to break the chain of poverty between generations through improving the conditions of education and health in PKH families which are obtained through FDS activities. The success of FDS cannot be separated from the use of communication media in improving the quality of beneficiary families as well as recipients of messages about education, health and improving the family economy. The method used in this study is a qualitative descriptive method. Research informants were determined by purposive sampling technique . Data collection techniques are carried out by means of observation, in-depth interviews (in- depth interview) and documentation. Data analysis procedures or techniques used are data reduction , data display , and conclusion drawing. The results of this study show Communication media in the form of videos, flipcarts and smart books that are used by PKH facilitators in the Family Development Session process make it very easy for mothers to receive material from their companions, and have a good impression on mothers participating in the family of hope program in Batu Putuk Village, Teluk Betung Barat, Bandar City. Lampung. In terms of health, education and economy, they are able to shape the mothers of PKH Beneficiaries into quality families.
