Abstract

Insects are the most dominant group of animals living on the face of the earth and their role is ecologically significant. The purpose of the study was to observe the type of population and identify the effect of  water level on the diversity of insect species found in the peat swamp area of Kuala Dua village. Data assesment was done by using survey method with systematic sampling. Observation plots was adjusted to the field conditions with water level 30, 40, 50 and 60 cm. The results showed that there were 15 insects species  belonging to 8 orders from 11 different families. The most common insects found in various TMAs that were observed, were Neurothemis fluctuan from the Odonata order. Physical conditions of the environment greatly affect the life of insects, such as having many types of plants which became food  for insects. It can be concluded that the level of diversity of insect species has a relationship with environmental conditions such as vegetation, pH, and water level.Keywords: Insect population, systematic sampling, water level

Abstract

Pulai (Alstonia scholaris) is a fast growing local species that can be used rehabilitation activities on peat swamp forest. This study aims to obtain information application the response of growth and quality of pulai seedlings to wood vinegar and shade. The research was carried out at orchid exsitu observation site stock  and community service and in the silvicultural laboratory of Faculty of Forestry. This study applied an experimental method with a split plot design with a complete randomized design (CRD). The treatment consisted of two factors,“shading” as the main factor and kind of  organic vinegar as  sub  factor. The results obtained were based on observations 12 weeks after planting, the growth percentage of pulai seedlings for the 100%, while ofthen variables in this study had no effect. The main factor is organic fertilizer with 2 levels: chemical fertilizer and wood vinegar, while the shade factor is a main factor that less interest. Results showed that the response of height growth was significantly higher 13.0% to chemical fertilizer than wood vinegar when planted in a shadeless condition. However, if planted in conditions with a shade of 60%, the response was no different. The response of leaves growth to fertilizer is significant when planted under different shade conditions. In the condition without shade, the response of leaves is 11.8% higher compared to wood vinegar. Conversely, in condition with shading 60%, the response  the number of leaves growth on wood vinegar was 13.0% higher than that of chemical fertilizer. In this study, the concentration of wood vinegar as much as 4% was not effective enough to increase the enhance  of pulai seedlings.Keywoards: Organic vinegar, pulai seedlings, shade

Abstract

The National Disaster Management Agency (BNPB) identifies eight provinces considered prone to forest and land fires in Indonesia. Four provinces are in Sumatra and four are in Kalimantan, one of which is West Kalimantan. Forest and land fires seem to have become a disaster in West Kalimantan, especially every dry season. Burning activies in the preparation of land for agriculture in the village of Rasau Jaya General is still using a relatively simple technology, namely the method of "slash and burn". The impacts caused by the peat fire process are in the form of water vapor from the combustion process in the air so that smoke formed which is very thick, causes environmental pollution and can affect soil conditions such as physical and chemical properties of peat soils. The purpose of this study was to obtain information about the effects of repeated burning on peatlands on soil characteristics in Rasau Jaya Umum Village, Kubu Raya Regency, West Kalimantan. This research was conducted by survey method and carried out with purposive sampling on 3 research sites, which were on land that had repeated burning twice, 4 times and 5 times. Soil physical properties observed were peat maturity (fiber content), water content, soil moisture, water level and bulk density. The level of fertility of peatlands is influenced by the chemical nature of the soil. The chemical nature of the soil is one of the limiting factors for knowing nutrients in the soil that are beneficial for plant growth. Determination of the level of soil fertility in peatlands can be done by analyzing the chemical properties of the soil. Analysis of the soil chemical properties includes analysis of the main element content such as acidity (pH), nitrogen (N), phosphorus (P), potassium (K) and cation exchange capacity (CEC). The physical properties of the soil consisting of the weight of the contents, the moisture content varies with different levels of burning, the higher the value of the weight of the contents, the more dense a soil and vice versa. In the value of water content, the amount of combustion influences the amount of ground water content, the more number of combustion, the value of water content also increases. Peat environmental conditions observed in the field consisted of soil moisture, soil temperature and ground water level measured for 7 days and obtained a mean value that also varied did not show its effect on the number of repeated fires. The chemical properties of peat soils on the number of repeated burning can increase and decrease each nutrient value consisting of N, P, K and also CEC. Nutrients that increase in the amount of combustion are pH, N, and CEC while the value of nutrients that decrease is K and P. This shows that the greater the level of combustion, the pH, N, and CEC greater.Keywords: peatlands, repeated burning, soil characteristics
