The study consists of several stages, namely: 1. Orientation field, 2. Experiment field, which includes soil sampling, measurement of temperature, humidity and pH of the soil, 3. Experiments in the laboratory which includes the extraction and identification of soil fauna, as well as the analysis of the content of C and N soil.
1. Orientation course Orientation field is intended to locate and determine the Dewapoker.com Poker Online Yang Pertama Dan Terbesar Di Indonesia appropriate location for research purposes to obtain the desired location of the study in accordance with the purpose of research. In this study determined the location of the research is in the Oil Palm Plantation Forest Area District of Hope Bejubang, Jambi Province. Geographically this region is located between 103015'0 south latitude and 205'0'', 5'' east longitude.
Field Experiment Soil sampling as a place to live Collembola performed using a drill with a soil sample ring diameter and 5 cm high. Soil sampling is done randomly. For soil sampling in Oil Palm Plantation Forest Area around Hope performed in 5 plots with each plot size of 50m x 50m. within each plot contained 5 subplots with the size of each subplot 5m x 5m. soil sampling done as much as 3 soil samples from each subplot (figure 3.1).
Figure 3.1. Soil sampling at each subplot
Soil samples will be taken once a month for six months, in other words taking three soil samples during the wet season and dry season three soil samples. Similarly, for the measurement of pH, temperature, and humidity done once a month for six months. The instrument used for the measurement of pH by using litmus paper is to take soil and mix with water and then measured. While the temperature measurement using a soil thermometer that is by plugging the ground and see the temperature changes that occur. For moisture measurement using the calculation of water content, using the formula: % Water = (B - (C - A)) / B x 100% A = weight of cup B = Weight of materials C = weight of dish + substance
Laboratory Experiment Analysis of N and C Analysis of N and C performed at the Laboratory of Soil and Environmental Biotechnology IPB ITSL. Analysis of N using the Kjeldahl method (1883), while for C analysis using the method of Walkley & Black.
Extraction Collembola Soil samples obtained from the field were brought to the KAISARBET.COM AGEN BOLA TERPERCAYA PIALA DUNIA 2014 laboratory to do eksteraksi process. The process of extraction is done by using the tool Kempson extractor for 7 days with a temperature of 60oC pounds. Soil fauna reservoir bottle containing ethylene glycol has been placed under the filter (Figure 2.3). After the extraction process is complete, then the soil fauna is stored in a container of 70% alcohol for identification.
