Abstract

Chili is an important commodity for most people, because of its function in terms of improving taste and appetite. Chili was seriously developed with the support of government funds for chili farmers. The development of chili plants, has enough obstacles, especially wich caused by plant disturbing organisms whether it is pests or diseases. The important organism that disturbs chili is wilting caused by Ralstonia solanacearum. In South Kalimantan, this disease reportedly attacked chilies spread in the districts of Banjar, Banjarbaru, Barito Kuala, Tapin, Hulu Sungai Tengah and Balangan with a cumulative attack area of 15,7 ha on 2017 (South Kalimantan BPTPH Database). This disease is important because of the nature of the attack which can cause the plants to wilt suddenly all part of the plant. Plants wich attacked by bacterial wilt cannot be cured. The effort that can be done in prevention before pathogens infect the plants (Sastra, 2004). One way to overcome this problem is biological control using biological agents from the type of antagonistic bacteria Bacillus spp, Pseudomonas fluorescens, and type of antagonistic fungus Trichoderma spp. From three biological agents proven able to inhibit the development of R. solanacearum in vitro which produces a zone of inhibition as wide as 13,5 mm for Bacillus spp, 22,25 mm for Pseudomonas fluorescens and 8,42 mm for Trichoderma spp. and can increase plant height growth, chili weight, root weight, wet weight, and dry weight plants. Trichoderma spp as the best biological agents for increasing chili growth and yield.

Abstract

The increasing needs and the nearness residential distance from the forest were several factors that caused society to do the utilization of the forest land. Sungai Langka village was a village directly adjacent to the Wan Abdul Rachman great forest park area, where most societies were farmers who manage the land inside the Wan Abdul Rachman great forest park area. The objective of this research i.e.: 1) To find out the species of plants cultivated by farmers on the land-based on habitus, plant groups, and commodities produced; 2) to count the density of each plant group; 3) to find out the most plants as a source of farmers incomes.  This research was conducted with a vegetation survey using the terraced line method. The number of sample plots used was 69 pieces measuring 20m x 20m, 10m x 10m, 5m x 5m, and 2m x 2m. The results of the study showed that there were  35 plants species on farmers cultivated land which is dominated by plants of the forest group MPTS with a density of 3,637.66 individuals/ha, forest wood plant 797,83 individuals/ha, agricultural MPTS 2,294.2 individuals/ha, and agricultural crops 1,533.34 individuals / ha.  Therefore, could be concluded that most of the plants on arable land were fruit-producing plants which were partially included in the MPTS forest group plants, and farmers rely on crops such as cocoa, banana, durian, clove, nutmeg, rubber, petai, pepper and vanilla as the source of income and fulfill their needs.

Abstract

Settlement growth and activity of the population in the Brebes Subdistrict upstream side is also predicted to trigger intrusion and rising sea levels that affect the flow and availability of fresh water needed for the survival of life mangrove vegetation, especially in the adult stage. Therefore, identification of the quality of waters in the mangrove areas is needed to determine the status of these waters pollution index. Measurement of physical and chemical parameters of waters in situ using a Water Quality Checker (DKK TOA WQC Type-24) and laboratory testing of some samples to determine the nutrient content of the water is also performed. Insitu value measurement results later are calculated by using a pollution index refers to the Decree of the State Minister of Environment Number 51 The year 2004 on Guidelines for Determination of Water Quality Status. Index of water pollution Brebes District mangrove area is divided into three criteria: pollution index good condition, lightly polluted and heavily polluted. The section near the front mangrove estuary and enter the index criteria lightly polluted.

Abstract

Forest certification is a key issue in relation to the forest products industry. It's also a new trend market of forest products. Forest certification is a guarantee that the products resulting from the forest management process in accordance with the standard of sustainable forest resources management. Certification will be increasing the cost of management as an impact of fulfilling requirement on the criteria of the certified forest. The fundamental question whether the award of certified products has been accompanied by an increase in premium price for forest estate or only becoming as the cost that reducing profit for the forest estate. The aims of this research are: 1) to know the difference between the sales price of certified and non-certified wood, 2) to know the premium price on certified forests, 3) to identify the factors that influence the amount of premium price of the certified forest. Data collection were used by searching the document and literature reference on forest certification. The results showed that the premium price received from the certified timber is higher than non-certified timber. Certified wood with high quality has a premium price that is greater than the low-quality wood. The percentage of premium price received varied forest estate. Premium price sometimes unsignificantly received by small-scale of timber estate. The revenue of premium price of certifies forest is influenced by the following factors: 1) The forest area to be certified, 2) Organizations that perform assessments, 3) Company / bodies / organizations that filed the certification, 4) he The country as a buyer of certified timber product 5) the facilitator in the market activities, 6) post-certification fee, and 7) the sales price.

Abstract

This study aims to analyze the structure of the mangrove forest stands in a conservation area PT. Indocement P12 Tarjun, South Kalimantan. To determine the potential amount of carbon stored in vegetation and soils di area mangrove forests. Merumuskah form of management in accordance with mangrove forests owned by PT Indocement Tunggal Tbk P 12 Tarjun. The results of this study show the type of vegetation that are within the plot observation is Aegicera corniculatum, Acivennia alba, Avicennia lanata, Avicennia Marina, Bruguera gymnorrhiza, Bruguiera parviflora, Ceriops decandra, Lumnitzera, Rhizophora apiculate, Rhizophora mucronata, Scyphiphora hydrophyllacea, Sonneratia alba, Xylocarpus granatum, Acanthus ebracteatus, Hibiscus tiliaceus, Nypa fruticans, Terminalia catappa and type of vegetation present in the area of research, but is not included in the observation plot is Acrostichum aureum Linn, Pandanus odoratissima. Importance Value Index (IVI) lenata kind Avicennia highest growth rate of the tree that is 80,2%, Rhizophora apiculata at the level of the pole that is 57%, and Nypa fruticans at the seedling stage is 20,8%. To Nypa fruticans, though IVIs largest/highest species of plants in the seedling stage but this type is only found on two research plots only. Total carbon content was found at the study site was at 714,77 per hectare. The study was conducted on biomass carbon on the surface, lower plants, nekromassa (dead trees), and mangrove sediments (ground). Carbon sequestration at a site can be seen from the height and diameter of trees while a vegetation type had no significant effect on the absorption of carbon. Environmental management in the form of replanting are research needs to be done to avoid more severe harm than good because of logging by humans atupun affected by coastal erosion. Type Lumnitzera, Scyphiphora hydrophyllacea, Ceriops decandra should get more attention because it has a very low INP hat is necessary to manage lebis so it can be adjusted with the handling principles of environmental factors such as tidal conditions, sediment, pH, salinity
