Abstract

Size inequality dynamics and allometric model of the self-thinning exponent of a crowded mangrove Kandelia obovata stands were analyzed by using five years data. Size variability and skewness of tree height, H and stem diameter of H, D0.1H, as well as the contributions of H and D0.1H on the tree mass, wT variation were analyzed. The Standard deviation SD of H decreased significantly by the vicinity of zero with stand growth, indicating that the variation of H becomes small as the stands grow, and finally all trees may have a similar height. On the other hand, SD of D0.1H was stable as the stands grew, while, the coefficient of variation CV of H significantly decreased as the stands grew. These results suggest that the size inequalities of H and D0.1H become small as the stands grow. Most of the skewness b1-values of H were negative meaning that most of the frequency distributions of H is J-shaped though stands grow. The self-thinning exponent was well-described by Weller’s allometric model, at which the value of  (8) was the same with  (1). This is because the value of  was nearly equal to 1/3, and the value of  was almost zero. Thus, the present study divulged that the size inequality of crowded mangrove actively self-thinned was dynamics, though their biomass density was significantly constant with the progress of time.

ABSTRACT This study aimed to determine the macro and micro mineral content of mangrove fruits (A. lanata, B. gymnorrhiza,and X. moluccensis). The samples used in this study were A. lanata, B. gymnorrhiza, and X. moluccensis mangrove plantswhich were taken fresh and ripe. Preliminary analysis of the micro mineral content of A. lanata, B. gymnorrhiza, and X.moluccensis mangroves was processed into a dry powder weighing 0.5 g of each sample. The fruit was mixed with asolution of HNO3 and 30% H2O2. Sodium (Na), Potassium (K), and Calcium (Ca) levels were analyzed using a flamephotometer. The micro-mineral content of A. lanata, B. gymnorrhiza, and X. moluccensis types were analyzed for iron (Fe),copper (Cu), manganese (Mn), and zinc (Zn) using the atomic absorption spectrophotometer. The results show that themacro-mineral content (sodium, potassium, and calcium) of the fruits of the three types of mangroves were significantlydifferent, where X. moluccensis showed the highest levels of macro minerals compared with mangrove fruits of B.gymnorrhiza and A. lanata. Micro mineral content (Iron and Zinc) of X. moluccensis was higher than B. gymnorrhiza and A.lanata while copper and manganese levels of B. gymnorrhiza mangrove were higher than X. moluccensis and A. lanata.Keywords; Macro and micro mineral, Mangrove, Foodstuffs ABSTRAK Penelitian ini bertujuan untuk mengetahui kandungan mineral makro dan mineral mikro buah mangrove (A. lanata,B. gymnorrhiza dan X. moluccensis).

Abstract

This study aimed to establish an allometric model for estimation of aboveground biomass, and carbon sequestration in A. lanata mangrove forest growing in Muna Regency, Southeast Sulawesi. Research methods were done by transect and 5 quadrats with size of 100 m2 each. A total of thirteen individual trees with different sizes were harvested. While DBH and D30 were measured. The samples were separated into stems, branches, and leaves and then weighted. The sample from each fresh organs were taken and brought to the Laboratory and then oven dried at 80°C for 7 days. The allometric equations were established by using independent variables (DBH and D30), and dependent variables (Ws, Wb, Wl). The partial and overall aboveground biomasses were calculated from allometric model, while carbon stock and CO2 sequestration were estimated. The results showed that the independent variable of DBH was more applicable for estimation of Ws, Wb, Wl, and total biomasses (Mg ha-1) of A. lanata forest, which were estimated as 28.28±3.48, 6.40±0.79, 5.00±0.66, and 40.08±4.97 respectively. The carbon stock in stems (13.24±1.63 Mg ha-1) was higher than in branches (3.01±0.37 Mg C ha-1) as well as in leaves (2.35±0.31 Mg C ha-1). The total of carbon stock were estimated at about 18.83±2.33 Mg C ha-1. Meanwhile, the total of CO2 absorption by A. lanata mangrove was 43.95±5.45 Mg CO2 ha-1. Therefore a regenerated A. lanata mangrove in this in-active pond area had potentiality on carbon stock and sequestrations, although these vegetation condition was still in the growth stage.

Abstract

The purposes of this study were to know the impact of different level of sea water inundation on the growth capacity and biochemical adaptation of the mangrove Rhizophoraceae family of Rhizophora mucronata and Bruguiera gymnorrhiza seedlings. The propagules of these mangroves were planted with different levels of sea water flooding, namely 90 cm, 60 cm, 45 cm and 30 cm. The growth of height and diameter of these mangrove seedlings were measured at early and termination of treatments, while their biochemical adaptations were analyzed in the Laboratory. The relatively growth rate RGR of high and diameter of these seedlings were analyzed, while statistical test was performed by anova. The RGR of high of the two mangrove seedlings were significantly different (P <0.05), though their RGR of diameter did not differ significantly (P> 0.05). The growth of height of R. mucronata seedlings was fastest at the lower level of inundation (30 cm) and the slowest at the higher level of submergence (90 cm). On the contrary, the height growth of B. gymnorrhiza seedlings was fastest at submergence of 90 cm, and the slowest at submergence of 30 cm. The flavonoids and vitamin C contents in both mangrove seedlings increased significantly (P <0.05) with increased inundation levels. Thus, although biochemical responses tended to be the same for both mangroves, but B. gymnorrhiza seedlings indicate  more able to grow and develop on rising sea levels than R. mucronata seedlings. This study provides important information for revegetation planning of degraded mangrove under a sea level rise scenario.Keywords: Biochemical adaptation, Sea water level, mangrove seedling growth, mangrove revegetation.

Senyawa kimia bahan antioksidaan teh hijau pada daun mangrove Bruguiera gymnorrhiza, B. parviflora, Rhizophora stylosa, R. mucronata, Lumnitzera racemosa, Ceriops tagal dan C. decandra dianalisis dengan GCMS, sedangkan khasiat teh hijau daun mangroves sebagai antikolesterol di ujikan pada mencit. Hasil penelitian menunjukan bahwa senyawa bahan teh hijau bervariasi diantara daun mangrove yaitu polifenol sederhana ditemukan pada daun semua jenis mangrove yang menjadi sampel penelitian dengan konsentrasi yang bervariasi. Senyawa katekin hanya ditemukan pada daun mangrove Ceriops decandra, L. racemosa, R. mucronata dan R. apiculata. Di sisi lain, flavonoid terdeteksi hanya pada daun C. tagal, B. gymnorrhiza dan R. stylosa, sedangkan senyawa T-flavin hanya ditemukan pada daun B. parviflora. Teh hijau daun mangrove mampu menurunkan kadar kolesterol mencit dengan kisaran 33,33 sampai 53,67% mengindikasikan besarnya potensi daun mangrove sebagai bahan  teh hijau antikolesterol.Kata kunci: bahan teh hijau, polifenol sederhana, katekin, flavonoid, antikolesterol, daun mangroveABSTRACTThis study aimed to determine the antioxidant properties of green tea material in mangrove leaves and elucidate their capacity on reducing the cholesterol of mice. The chemical properties in  leaves of Bruguiera gymnorrhiza, B. parviflora, Rhizophora stylosa, R. mucronata, Lumnitzera racemosa, Ceriops tagal and C. decandra were analyzed by GCMS, while their capability as anticholesterol of mice were examined. The results showed that simple polyphenols were found in all sampled mangrove leaves with different concentration, while the chatechine was found only in leaves of four mangroves including Ceriops decandra, L. racemosa, R. mucronata and R. apiculata. On the other hand, flavonoids was detected only in leaves of C. tagal,  B. gymnorrhiza and R. stylosa. Meanwhile, T-flavine was detected only in leaves of B. parviflora. However, green tea material for all of sampled mangroves showed high capacity to reduce cholesterol of mice that ranging from 33.33% to 53.67%, which indicated high potentitiality of mangroves leaves as green tea material of anticholesterol.Keywords: Green tea material, simple polyphenol, cathechin, flavonoid, anticholesterol, Mangroves leaves
