Abstract

The Giam Siak Kecil-Bukit Batu Biosphere Reserve was managed by zonation as a approach for multibenefitof management goals. This Bioshere Reserve has a fairly high carbon stock stored in its naturalpeat swamp forest ecosystems. Nevertheless, the condition of the peat swamp forest in the BiosphereGiam Siak Kecil-Bukit Batu currently has been destructed, especially in the buffer and transition zones.The threats of protected areas are not only coming from forest fire factors, but also from encroachmentand illegal logging. Therefore, it requires a recovery effort. This research aims to determine the survivalrate and to estimate the above ground biomass accumulation of the main tree species of peat swamp forestthat used to restore the burnt peat. The estimated total biomass accumulation on the surface was measured using allometric equations. Result of this research proved that Jelutung tree (Dyera polyphylla) has thebest survival rate among the trees (98%), while banana tree (Mezzettia parviflora) has lower survival rate( 35%). The highest total biomass accumulation was found in Jelutung (Dyera polyphylla) (499.015kg/ha/year, while the lowest total biomass accumulation was found in Meranti batu (Shorea uliginosa)(88.867 kg/ha/year). A total of nine pioneer species were identified i.e. Tenggek burung (Euodia sp),kayu ara (Ficus sp), mahang (Macaranga triloba), karet (Havea brasiliensis), sendayan (Scleriasumatrensis), alang-alang (Imperata cylindrica), senduduk (Melastoma malabathricum), paku-pakuan(Neprolepis hirsutula) and rumput teki (Cyperus rotundus). The total biomass accumulation of earlysuccession in all types of vegetation pioneer is 338,91 kg/ha.Key words: Above Ground Biomass Accumulation, restoration, vegetasion succession, burned peatland,Survival Rate.

Abstract

The universal health social security program in Indonesia began in 2014, and as of the present day, many people are now covered by it. However, many weaknesses in the system have been pointed out. Significantly, many people do not possess the necessary health cards to take advantage of the program due to the complicated process one must go through in order to obtain them. Even now, 60 million people have not joined the program. Many people do not rely solely on the universal social security program but may be supported primarily or additionally by the vernacular care system, whereby support is provided by their family, friends and community. This study intends to understand and analyze the vernacular care system found in rural West Java, Indonesia, with particular focus being given to the elderly’s engagement with it. This study is mainly based on field work that surveyed 64 households with a socio-economic household survey being conducted alongside in-depth interviews with elderly people who received medical check-ups in 2003. This study shows the importance of care; not only that which is provided by the children of elderly parents, but also the grandchildren. In cases where children migrate from their family homes, elderly family members are supported not only through remittance, but also by having their grandchildren live with them. Otherwise, the characteristics of the informal sector occupations enable people to continue living in and around the village that their families are based so that their children, children-in-law, and grandchildren can care for the elderly.
