Abstract

Global warming and greenhouse gas emissions (GHGs) became a hot issue in the world today. An increased concentration of carbon in the atmosphere becomes one of the serious problems that can affect life on Earth. Peatlands pointed out as one of the sources of GHG emissions. Drainage of peatlands cause decreased water level so that the decomposition process is faster on a layer above the groundwater table, thus affecting the chemical characteristics of peat. In addition to affecting the ground water level, drainage also leads to a decrease in surface height peat soil (subsidence). Given the magnitude of the role of drainage and land use types in affecting carbon stocks and emissions of CO2 on peat soil, this study is to measure carbon stocks and emissions of CO2 on peat soil in forests and shrubs that have been drained. CO2 emissions increase with the closer spacing of the drainage channel that is at a distance of 50 m to 500 m of drainage channels. Meanwhile, at a distance of 5 m and 10 m of the drainage channel can not be concluded because of the condition of ground water that is stagnant at the time of sampling gas, so be very low CO2 emissions. CO2 emissions on the use of forest land are higher than the shrub land.

Abstract

Polymerase Chain Reaction (PCR)-based molecular techniques have been used to detect the polymorphism in plants. The utilization of molecular markers plays essential role in germplasm characterization and plant breeding since the information of DNA marker technology can be exchanged between laboratories and should have standard method to be reproducible. The molecular aspect has been commonly linked to DNA isolation protocol and polymorphic molecular marker, thus can be used for molecular research recommendation purposes. The objectives of this study were to evaluate the capability of microsatellite marker of Ebenaceae Family for amplifying Ebony DNA, and to determine the appropriate PCR annealing temperatures. The DNA isolation of Ebony leaves from Experimental Forest of Hasanuddin University Provenance was carried out using Genomic DNA Mini Kit (Plant) Geneaid protocol. Nine of seventeen selected primers from the Genus Diospyros were able to amplify Ebony DNA. Amplification products produced polymorphic bands with different annealing temperatures (ranged from 53 to 56°C). These nine polymorphic primers will be recommended to use for future studies in genetic diversity as well as pollen dispersal pattern analyses.

Abstract

A field experiment was aimed at investigating the effect of natural guano organic fertilizers on growth and yield of Spring Onion (Allium fistulosum L.). The experiment was conducted from September to Nopember, 2014 in Unamendaa Village, Kolaka District. It was prepared by using a randomized block design  (RBD) with single factor namely doses of natural guano organic fertilizers. The treatments consisted of 4 levels were : (1) G0 = control or no treatment, (2) G1 = dose of 6 kg unit-1 (equivalent to 5 t. ha-1), (3) G2 = dose of 12 kg unit-1 (equivalent to 10 t. ha-1) and (4) G3 = dose of 18 kg unit-1 (equivalent to 15 t. ha-1), respectively. Every treatment was replicated 3 times, therefore overall there were 12 experimental units. Data was collected on growth and yield parameters of Spring Onion : (1) plant height, (2) number of leaves, (3) number of tillers, (4) diameters of stem and (5) yield (plant fresh weight unit-1). Data obtained were analyzed using Analysis of Variance (Anova) and followed by Duncan’s Multiple Range Test (DMRT) at the 1 % level. The result of experiments showed that fertilizations using natural guano organic was significantly affected on : plant height, number of leaves, number of tillers, diameter of stem and plant fresh weight, respectively. Untill fertilization of 18 kg unit-1 (G3) were able to increased the growth and yield of Spring Onion, hence it was showed better performance on all parameters

Abstract

People of Kolaka accustomed to using coconuts as well be used as a food supplement or a mixture of additives in processed foods, cakes and other confectionary. Therefore utilizing coconut pulp as feed fish and poultry should be made to minimize the potential for household waste. Feed from coconut pulp is a transfer of science and technology to the people who are expected to help poor people to be productive. Fermentation is one method to process coconut pulp into feed ingredients. The fermentation process is done by using spores of Aspergillus niger. The fermentation process is done in stages, by aerobic fermentation followed by anaerobic fermentation (enzymatic process). In short the process of making feed "PA-BIO" from coconut pulp is: Dregs of coconuts added water, stirred and steamed. Cooled and then stirred together with a mixture of minerals, Aspergillus niger spores are added and stirred again until evenly distributed. The mixture was then fermented aerobically and unaerobically. Dregs fermented and then dried and packaged for later in packing. Based on the results of research that the utilization of coconut dregs as cattle feed and fish is potential. Miskiyah et al. (2006), increase protein content after fermentation of coconut pulp 11.35% to 26.09%, or by 130% and decreased fat content of 11.39%. The results also showed that the feed produced quite safe for livestock, namely the aflatoxin content 20 ppb. Feed from coconut pulp is also good for fish farming. Goenarso et al. (2002) on tilapia (Oreochromis niloticus L.), the faster fish growth with increasing the feed protein content of 25%, 30%, 35%, 40% and 45%.

Abstract

The cultivation of tomato in lowland experience many obstacles, such as low produvtivity. One effort to increase tomato productivity  in lowland is through selection of tomato genotype for high yield and yield component  in lowland. This study aims to determine the variability based on genetic information, heritability and correlation of characters as well as the yield components of tomato genotypes relationship patterns in the lowlands. A Randomized Complete Block Design was used to characterization base on best genotype of yield component character, genetic variability, broad sense heribility and correlation to yield. Genotype of tomato tested had diverse characteristics. Best genotypes based on the yield character is IPB T1, based on the number of fruit per plant is IPBT30, based on the fruit length and day to flowering is IPB T74, based on the fruit diameter is IPB T73 and fruit thickness is IPBT60. Wide genetic diversity has a high heritability. Number of fruit per plant, fruit length, fruit diameter, and fruit thickness has a wide genetic diversity and high heritability. Yield characters has a narrow genetic diversity and heritability is low. Characters that have a direct impact on the yield are the fruit diameter. Based on the cluster analysis, tomato genotypes are grouped into five groups. Group I consists of seven genotypes (IPBT1, IPBT58, IPBT60, IPBT64, IPBT78, IPBT80 and IPBT82), group II consists of one genotype (IPBT74), group III consists of three genotypes (IPB T13, IPB T73 and IPB T86), group IV consists of five genotypes (IPBT3, IPBT33, IPBT43, IPBT53, and IPBT3) which is characterized by fruit thickness, fruit length and days to flowering, and group V consists of one genotype (IPBT30).
