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

The Southeast Sulawesi government has designated Kolaka Timur as one of the cocoa production centers in Southeast Sulawesi. One of the successes of the superior seed assembly business depends on the availability of complete and accurate information about the potential of cocoa to be chosen as elders for subsequent development, so that yield analysis and early selection in the analysis of genetic diversity of smallholder cocoa have been developed in that location. This research was carried out using the Split-Plot Design (RPT). Sampling was carried out in 3 main locations (L) with an area of ± 2 ha, in each of the main locations divided into three plots (P) namely plots one Sulawesi 2 clones, plots two local clones and plots 3 MCC02 clones. A sampling of cacao leaves and fruit was taken as many as 30 samples with three replications per location. The results showed that cocoa which has the potential for good yields to be developed in the East Kolaka Regency based on the analysis of the component production of dry seed weight was the MCC02 cocoa clone with an average of 35.33 grams of fruit (L2P3) respectively. The different locations show different levels of Cacao yield and adaptation

Abstract

Palm oil production is related to the number of fruit and is thought to be determined since the beginning of the flowering phase as the initial stage of fruit formation. Identification of oil palm flowing genes needs to be done as the first step of knowing the mechanism of flowering in oil palm molecular. Oil male and palm females contain high polysaccharides and polyphenolic compounds so they can inhibit the process of molecular identification. Molecular studies provide accurate and fast information about the potential of oil palm genetics as a commercial commercial commodity. The purity and concentration of DNA and the temperature of annealing are the main requirements for PCR-based molecular studies. The purpose of this study obtained the extraction method of oil palm flowers which produced high DNA concentration and purity and optimized the temperature of annealing to identify the flowering gene. DNA from male flower spike and female flowers is extracted using the A (SDS) method, method B (CTAB), method C (CTAB + PVP), and method D (commercial kit). Primary BMS annealing temperature for amplification of optimized flowering genes using PCR gradients. The extraction of male flowers and female flowers using the C (CTAB + PVP) method produces the best DNA concentration and purity compared to other methods. The best annealing temperature for male flower DNA amplification and female flowers using the BMS primer is 61.1 o C. Amplification of male flowers and female flowers using Primary BMS produces 1200 PB products. The results of DNA extraction and PCR amplification using the BMS primers in female flower samples are better than male flowers

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.
