Abstract

Climate change caused by increasing greenhouse gas emissions, especially CO2, and deforestation, is an urgent global issue. The REDD+ program initiated by the UN aims to reduce carbon emissions and increase carbon storage in forests. This research aims to measure and analyze biomass and organic and inorganic carbon reserves in the Silokek Geopark area, Sijunjung Regency. The method used in this research is non-destructive sampling and using a destructive sampling method. Transects were carried out using the transect method using purposive sampling and were made in 10 plots 100 m long with square plots measuring 10x10 m for trees, 5x5 m for saplings, and 2x2 m for undergrowth. Next, the limestone samples used the chip sampling method and XRF analysis. The research results showed that the total organic biomass was 326,748 tons/ha, carbon reserves were 153,571 tons/ha, and carbon absorption was 563,607 tons/ha, which is categorized as high. The inorganic carbon content in the Silokek Geopark karst area is 4,908.07 tons/ha and inorganic carbon absorption is 18,012.60 tons/ha

Abstract

Kersen leaves are a herbal plant that has various health benefits, especially as a medicine for diabetes sufferers. Kersen leaves can be processed into tea bags, but they still have sensory deficiencies in terms of color, aroma and taste. This research aims to determine the effect of adding jasmine flowers and cinnamon and their interaction on the sensory and physical characteristics of kersen leaf tea bags. The method used in this research was a Complete Randomized Block Design (RAKL) with two factors, namely the addition of jasmine flowers which consisted of 3 levels, namely M1 (10%), M2 (20%) and M3 (30%). The second factor, namely the addition of cinnamon powder, consists of 6 levels, namely K0 (0%), K1 (3%), K2 (6%), K3 (9%), K4 (12%) and K5 (15%). The data obtained were analyzed for variance and analyzed further with further Orthogonal Polynomial tests at the 5% and 1% levels. The results of the research showed that the addition of jasmine flowers and cinnamon had a very significant effect on the color, aroma and taste as well as the brightness level of the kersen leaf tea bag. The interaction between the two has a real influence on the color and taste as well as the brightness level of the brew but has no real influence on the aroma of kersen leaf tea bags. Based on research results, kersen leaf tea bags with the addition of jasmine flower concentration of 10% (w/w) and cinnamon concentration of 15% (w/w) produced the best treatment with color value of4.167  (brownish  yellow),  aroma  value  of  3.875  (not  unpleasant), taste  value  4.000  (not  bitter),  brew brightness level value of 22.850, water content value of 6.9% and ash content value of 5.9%.

Abstract

Climate change caused by increasing greenhouse gas emissions, especially CO2, and deforestation, is an urgent global issue. The REDD+ program initiated by the UN aims to reduce carbon emissions and increase carbon storage in forests. One of the forests that can reserve carbon is the karst area with the ability to reserve carbon dioxide (CO2). This study aims to determine the potential carbon content and carbon dioxide (CO2) sequestration. This study was conducted using the chip sampling method and the XRF (X-ray Fluorescence) method analysis. Based on the research results, it is known that the Silokek Geopark karst area has three different limestone rock characteristics, and sample 3 is the type of rock with the highest CaO percentage. The potential inorganic carbon content is 4,908.07 tons/ha and carbon absorption is 18,012.60 tons/ha, categorized as high. The inorganic carbon content in the Silokek Geopark area is lower than the Biduk-biduk Karst area which is influenced by the area volume area and type of rock composition.
