Abstract

Both biotic and abiotic natural resources are the capital of the biosphere that may be exploited to meet human needs and promote human welfare. Global warming is a consequence of increasing environmental degradation. During photosynthesis, trees may collect carbon from the atmosphere, separate carbon from oxygen, and release oxygen back into the atmosphere. This investigation was conducted on post-coal mining reclamation land that PT. Bukit Asam (BA) restored in 2009, 2012, and 2015. This study employs a quantitative approach with a purposive sampling methodology. The utilized sampling intensities were 1%, 2.5%, and 5%. The plot chosen is a 20-by-20-meter rectangle. Carbon storage for the 2009 planting time averaged 40.57 tons per hectare over a total area of 32.89 ha. Carbon storage for the planting year of 2012 with a total area of 5.73 hectares and an average carbon storage of 26.37 tons per hectare. Carbon sequestration in 2015 with a total area of 3.90 hectares and an average carbon storage of 20.86 tons per hectare.

Abstract

The Sonor farming system is an agricultural system that clears land by burning, which is a tradision arried out by the people of Secondong Village. The Sonor system is one of the couses of land fires in South Sumatra. This study aims to analyze community community knowledge of sonor farming systems, analyze the factors that influence people's knowledge of sonor farming and community attitudes that can be done to prevent sonor farming. The research was conducted in Secondong Village, Pampangan District, OKI Regency, South Sumatra Province in August 2019. Using a survey method with descriptive qualitative data analysis and a Likert Scale test. The results showed that 77% of the people of Secondong Village carried out land burning, the people of Scondong Village had quite high knowledge about sonor farming systems which were considered an effective and efficient and cost-effective method. There are two factors that affect the public's interest in burning land, namely the lack of public understanding of the impacts of land burning (75%) and habits that have been passed down from generation to generation (73%), the absence of counseling so that there is no land clearing in other ways. Communities have good potential to prevent sonor farming systems (82%) if supported by extension activities and environmentally friendly technologies for clearing agricultural land.

Abstract

HTI is an industrial plantation forest built in order to increase the potential and quality of production forests by implementing intensive silviculture to meet the needs of industrial raw materials such as wood processing, pulp, and paper. In South Sumatra there is HTI PT. Musi Hutan Persada (MHP) which is one of the largest industrial plantation forest companies in Indonesia. Initially, PT, MHP only planted and produced Acacia Crassicarpa, Acacia Auriculifomis, Acacia Mangium, but now it has been combined with Eucalyptus pellita which is one of the priority types developed in HTI management to obtain its wood fiber. This study was conducted to determine the Eucalyptus pellita plants attacked by pests, the percentage of pest attacks and the level of damage caused by pests. The research method used is a quantitative method, by making transects and observations of Eucalyptus pellita attacked by pests. There are three types of pest attacks found, namely the Zeuzera coffea pest attack on Eucalyptus pellita plants with symptoms of fractures at the base of the stem, swelling and hollow stems. Homona coffearia pest attacks with symptoms of perforated leaves and cut leaf edges or bite marks from pests. Symptoms of Helopeltis sp attacks with symptoms of punctures on the leaves that can cause the leaves to dry and die or if they are still growing the surface of the leaf skin cracks and shrivels. The percentage of Zeuzera coffea pest attacks occurs more in old plants at the age of 6 months only ± 0.002%, the age of 16 months increases ± 0.0277% and at the age of 26 months it is even higher to 0.0580%. While for Homona coffearia and Helopeltis sp pests, they attack young plants more, the older the plant the percentage of pest attacks decreases. During the two-month observation, the percentage of Homona coffearia attacks decreased from 0.0048% to 0.0030%. Likewise with the percentage of Helopeltis sp attacks 0.0090% to 0.0089%. The level of damage to plants due to Zeuzera coffea pests increases with increasing age in plants aged 6 months (0.0004%), 16 months (0.0071%), 26 months (0.0076%). While the level of damage due to Homona coffearia and Helopeltis sp decreases with increasing age of the plant, damage from leaf rollers from 0.0012% to 0.0007%. The level of shoot damage from 0.0023% to 0.0022%.
