Abstract

Quartz sand is the main component of soil in heath forest floor which is very fragile in respond to any disturbance. The damaged heath forest after quartz sand has been mined, was very difficult to restore. Therefore, study on biophysical characteristics of primary and secondary heath forest are very important for improving forest rehabilitation efforts. After that, identification of tree species which is most suitable for the site in the rehabilitation program is very urgent. The research results showed that white jabon (Anthocephalus cadamba (Roxb.) Miq.) exhibited the greatest increase in height , diameter and dry weight (biomass). Therefore, white jabon is the best choice for rehabilitation on tailing of former quartz mined area. Planting media which are composed of tailing and organic matter (compost) is the best media for tree growth in rehabilitation program. The research results can serve as one of the guidances for stakeholders to manage heath forest in East Belitung Regency and as reference for rehabilitation activities.Key words: quartz sand, rehabilitation, tailing, white jabon

Abstract

The success of mangrove rehabilitations are influenced by various factors which one of them is the availability of seedling stocks over time. The knowledge about growth process and development of plants which will be used as seedlings are several factors of success of nursery development. Red mangrove (Rhizophora mucronata) is one species of plants which grows in mangrove forest. The conservation of this species is very important because its habitat is at the central zone of mangrove formation and has high reproduction over time so it can be easier to do rehabilitation. The aim of this research is to get the information about R.mucronata growth and development to get better cultivation technique. The treatments were planting of propagule that had pieces of fruit and planting of propagul without pieces of fruit. Based on this research, the planting of propagule without pieces of fruit gave significant effect toward the heigth and length of red mangrove (R.mucronata) propagules development.Key words : growth, nursery, propagule, Rhizophora mucronata

Abstract

There are several factors affecting plant biomass, carbon stock, CO2-equivalent, and oxygen production (net O2 release), such as plant species (chlorophyll quality and leaf area), plant age, temperature, sunlight and land quality (water and nutrient availability). To estimate how much reclamation activity in post mining area has succeed in restoring plant biomass, carbon stock, CO2-equivalent, and net O2 release, especially post silica mining, a study to measure Pinus merkusii biomass, carbon stock, CO2-equivalent, and net O2 release planted in the area is undertaken. The study took place in Holcim Educational Forest (HEF) post silica mine reclamation area and Gunung Walat Education Forest (HPGW) as comparison site (non-reclamation). There are two age classes of Pinus merkusii being studied, those planted in 2005 and 2012. Study result shows that biomass of pine stand planted in 2005 on HPGW non-reclamation area is higher than on HEF reclamation area. The same result also occur on carbon stock, CO2-equivalent, and net O2 release measurement. However on the contrary, pine stand planted in 2012 on HEF reclamation area, have higher biomass compared with pine stand planted in 2012 on HPGW. The same result also occur on carbon stock, net O2 release and CO2-equivalent measurement, which is higher on pine stand planted in 2012 on HEF reclamation area. Overall soil quality analysis result, especially macro nutrient and micro nutrient, shows that on both site and both stand ages have relatively low macro nutrient content, except for high Mg content on 2012 pine stand in HPGW non reclamation area and very high S-available content in HEF reclamation area on both age classes. All micro nutrient analysis shows that on both age classes and on both area have medium micro nutrient content, except for very low Al content and very high Mn content.Key words: biomass, carbon stock, Pinus merkusii, reclamation, soil quality

Abstract

The United States Government and the Indonesian Government have agreed on a treaty to reduce deforestation called the TFCA Sumatra Program (Tropical Forest Conservation Action-Sumatera). Development of community forests is expected to reduce the rate of deforestation. However, the pattern of effective community forest management to be applied in reducing the rate of deforestation in Sumatera was unknown, especially in the TFCA program in Bengkulu. The study was conducted in Air Sulau Village and Kayu Ajaran Village, South Bengkulu Regency. The respondents selection was conducted by purposive sampling. This study aimed to analyze the pattern of community forest management in the TFCA Sumatera in Bengkulu. The data was collected using observations, interviews, and literature study. The analysis was performed using descriptive-qualitative and quantitative methods. The results showed that the pattern of development community forests in the TFCA program in Bengkulu was agroforestry with predominantly agricultural crops such as rubber. Meanwhile, woody plants such as albizia have just been developed on community forest enterprises in Bengkulu, combined with seasonal crops such as cassava and maize, or with herbs like turmeric and ginger. Based on the fund sources, the community forest pattern in TFCA Sumatera in Bengkulu belongs to the community forest pattern with full subsidy.Keywords: Community forests, TFCA-Sumatera, agroforestry, development patterns
