In addition to the 300 ha rehabilitation has been carried out with surrounding community such as Seponjen Village, quality improvement efforts also needed to reduce of access to collect directly the forest product from TAHURA. Its considered to interfere an imbalance of interests, both of conserving biodiversity and its ecosystem interests and the interests of the community's needs for the region. We offer solutions to build alternative livelihoods by managing floating cages collectively so that the community access efforts into Tahura area be diminishing. Based on our program that have been carried out, as many as more than 100% of the 30 target communities attended the seminar on forest fires and efforts to improve their microeconomics. The acccustomary people who fishing in TAHURA have been given the knowledge and techniques of floating cage cultivation, making peat water level monitoring equipment, and composting using simple technology. They was formed into 4 groups consisting of 5 people created their cages together on the Kumpeh River of Seponjen Village. This program will continue to be monitored and we hope the fish produced can be sustain in large quantities, while reducing the dependence of the community on Tahura.

Rehabilitation efforts have been carried out by The Korea Indonesia Forest Center (KIFC) through planting activities covering an area of 200 ha. The purpose of the study was to determine the survival rate of rehabilitation plants in the showing window area. A total of 6 (six) measuring plots were placed in the showing window area along the main inpection road of the rehabilitation area. Each measuring plot is made 25 m x 40 m so that the area is 0.1 ha. Measurement data include the number of living plants, plant height and plant diameter. The results showed that the survival rate of rehabilitation plant in the showing window area was 100%. Rehabilitation plant growth was also very good with the average height and diameter of Dyera lowii respectively 58.91 cm and 13.44 mm, Alstonia penumatophor...

The flames on the burning peat mix with water vapor inside the peat and produce a lot of smoke. The carbon which was previously buried in the soil and stored in stands above it became exposed and united in the life and human environment. It is very important to know the total carbon stocks in peat to see its contribution as carbon sequestration and carbon storage in stabilizing the ecosystem for rehabilitating peatlands in the tropics which are the lungs of the world. This research is limited to the estimation of carbon stocks stored in peat and understorey soil at the rehabilitation site of the Orang Kayo Hitam forest park. The estimation of soil carbon stocks is carried out by measuring the depth of peat at 48 drill points that are systematically placed. The estimation of understorey carbon stocks is carried out by destructive sampling method on a 0,5 x 0,5 met...

According to the assessment, 14 districts in priority 1 (severely vulnerable to food insecurity) were all in Papua. Responding to the problems of food insecurity, a multi-year program focusing on two regencies, i.e., Manokwari and Merauke, was conducted from August 2015. The program was developed in cooperation with the Ministry of Villages, Disadvantaged Regions and Transmigration (Kemendes PDTT), Gadjah Mada University Yogyakarta and district governments. This research aimed to examine the problems causing food insecurity and to develop integrative and collaborative macro-scale policy recommendations. The study used a qualitative descriptive method and a pilot project approach to address food insecurity problems in both regencies. It found five main issues related to food...

Kranji (Pongamia pinnata)) is an exotic fast-growing species whose tolerance to drought conditions and marginal soils are potential for the revegetation of degraded areas. This research aimed to analyze the effect of coal mining media, watering interval, and their interaction on the growth of kranji seedlings. This research was conducted in October 2015 with a 4-months observations period. The research used a completely randomized factorial design comprising soil media and watering interval. Three soil media treatments comprising secondary forest soil, disposal, and overburden in coal mining media were performed in PT Berau Coal, Berau, East Kalimantan. The watering interval was every 3 and 7 days. Organic pot made from leaf litter was used as basic treatment in this research, and kranji see...

Rehabilitation of extremely degraded areas through re-vegetation by fast growing species is expected to speedily recover their dynamic of organic-carbon stocks.The purposes of the study were to compare carbon stock in the aboveground biomass, understorey, litters, and soil organic under land use changes areas of open coal mining areas. The study was conducted in the coal mine concession area of PT. Berau Coal, at Site Binungan in Berau, East Kalimantan, Indonesia from September 2013 to October 2014. Data were collected from 10 plots representing ecosystem dynamics of coal mining land, consisting of: secondary forest, degraded forest; non-active mining pits; backfilling post-mining; re-vegetation forest by 2 years-old Johar (Senna siamea) stand; 1, 3 and 7 years-old Sengon (Paraserianthes falcataria); mixed forest 7 years-old Sengon (Paraserianthes falcataria) and 3 years-old meranti (Shorea sp.), and mixed forest of 9 years-old mangium (Acacia mangium) and 2.6 yearsold Shorea sp. Allometric method was used to calculate the aboveground biomass and their carbon stocks. Destructive method was used to obtain the biomass of understorey, litters, and soil organic carbon. The re-vegetation programs with fast growing species after 9 year rehabilitation at post-open-mining land in tropical areas were able to restore aboveground biomass at two-thirds of previous secondary forest ecosystem. Understorey biomass in the 1-9 years-old of fast growing species were ranges at 0.19-0.95 Mg C.ha-1. Carbon stocks in the litter of 7-years-old sengon re-vegetation area were higher than that of natural forest, because of their supply from litterfall and understorey. Soil organic carbon in re-vegetation areas of 9-years-old Acacia mangium stand was 23.2 Mg.ha-1 , almost equal to the value at the former secondary forest (28.5 Mg.ha-1), whereas its value during land clearing just only 4.3 Mg.ha-1. Environmental restoration in open coal mining areas through re-vegetation by fast growing plantation will restore their biomass and carbon stocks, nearly similar to their former secondary forest conditions.
