Tropical forests are among the most diverse ecosystems in the world, completed by huge biodiversity. An expansion in natural resource extraction through open-pit mining activities leads to increasing land and tropical forest degradation. Proper science-based practices are needed as an effort to reclaim their function. This paper summarizes the existing practice of coal mining, covering the regulatory aspects and their reclamation obligations, the practices of coal mining from various sites with different land characteristics, and the reclamation efforts of the post-mining landscapes in Indonesia. The regulations issued accommodate the difference between mining land inside the forest area and outside the forest area, especially in the aspect of the permit authority and in evaluating the success rate of reclamation. In coal-mining practices, this paper describes starting from land clearing activities and followed by storing soil layers and overburden materials. In this step, proper handling of potentially acid-forming materials is crucial to prevent acid mine drainage. At the reclamation stage, this paper sequentially presents research results and the field applications in rearranging the overburden and soil materials, controlling acid mine drainage and erosion, and managing the drainage system, settling ponds, and pit lakes. Many efforts to reclaim post-coal-mining lands and their success rate have been reported and highlighted. Several success stories describe that post-coal-mining lands can be returned to forests that provide ecosystem services and goods. A set of science-based best management practices for post-coal-mine reforestation is needed to develop to promote the success of forest reclamation and restoration in post-coal-mining lands through the planting of high-value hardwood trees, increasing trees’ survival rates and growth, and accelerating the establishment of forest habitat through the application of proper tree planting technique. The monitoring and evaluation aspect is also crucial, as corrective action may be taken considering the different success rates for different site characteristics.

Non-Timber Forest Products (NTFPs) management can lead to various benefits for community livelihood and forest sustainability. However, such management has not been carried out optimally and sustainably in Indonesia, due to various limiting factors including ineffective policies, undeveloped cultivation technologies, and inadequate innovation in processing technologies. Further, the diversity of NTFPs species requires that policy-makers determine the priority species to be developed. Agarwood (Aquilaria spp. and Gyrinops spp.), benzoin (Styrax spp.), sandalwood (Santalum album L.), and cajuput (Melaleuca cajuputi Powell) are aromatic NTFPs species in Indonesia that forest-dwellers have utilized across generations. This paper reviews the current governance, cultivation systems, processing and valuation, and benefits and uses of these species. We also highlights the future challenges and prospects of these NTFPs species, which are expected to be useful in designing NTFPs governance, in order to maximize the associated benefits for the farmers and all related stakeholders.

The "tasty" cuisine tends to use chemical flavour agent containing monosodium glutamate (M.S.G.). M.S.G. utilizations, in long-term, may cause health problems, especially triggering cancer cells. Therefore necessary to introducing and increasing a natural flavouring agent to eliminate those health problem, such as bekai leaf. Bekai (Pycnarrhena tumefacta Miers) is familiar as a natural flavour agent (bio-vetsin) in cuisine for forest communities in Nyapa Indah Village, Berau, East Kalimantan, Indonesia. However, until now there has been no proper analysis support for widespread utilization of bekai leaf. This paper studies the presence of phytochemicals, antioxidant and GC MS analysis from bekai leaf extracts, as well as five hedonic classifications of organoleptic test, to reinforce the need for a better understanding of consumers reaction in terms of possible acceptance of additional bekai leaves applied in soup as bio-vetsin. Present study showed that the qualitative screening of phytochemical compounds in bekai leaves ethanolic extracts revealed presence of alkaloids, flavonoids, tannins and steroids. Antioxidants of bekai leaves using 2,2-diphenyl-1-picrylhydrazy (DPPH) method showed that concentrated extract has 80.1%, which predicted can improve immune for inhibitory action of cancer cells. GC MS analysis suspected that bekai leaf extract contained 5 (five) major compounds, i.e. oxirane dodecyl, gamma sitosterol, vitamin E (α tokoferol), 9.12-Octadecadienoic acid (Z,Z)- (natural linoleic acid), and 3-Tetradecanynoic acid (myristic acid). These chemical compound in related with their phytochemical were predicted to contained strong antioxidant activities and some of them commonly used as flavour agent in cuisine for some food industries. Meanwhile, results of organoleptic tests presence in three soup variant have been provided that soup with additional Bekai leaves has best acceptance in the children's perception due to it has an unique smell, tasty and no colour changing compared with M.S.G. added and control. Thus bekai leaf can be used as an innovation for healthy food and new market opportunities for M.S.G. substitutes.

KEANEKARAGAMAN JENIS JAMUR EKTOMIKORIZA PADA EKOSISTEM HUTAN DIPTEROKARPA DI KHDTK LABANAN, BERAU, KALIMANTAN TIMUR

Yellow Bitter Charm (YBC) has been widely known as medicinal plants in Dipterocarps forest ecosystem. Common utilization of YBC is roots and stems, causing problems with its sustainability. In this study, some active compounds contained in YBC leave were identified due to antioxidant of YBC leaf is higher than root and stem. Thus, efficacious diversification products from it leaves as herbal tea was introduced. YBC leaves were taken from Samboja (East Kalimantan), Kotawaringin Timur and Katingan (Central Kalimantan). Chemical compounds showed that YBC leaves contained some important compounds, namely: canthin (anti-cancer), ethanol (aphrodisiac), anti-malaria (eurycomanone), and anti-HIV (quainoid), while other active compounds were saponins, tannins and alkaloids are very good for improving blood circulation. Herbal tea products from YBC leaves are made into 3 flavors, namely: original, jasmine and lime aroma. Organoleptic tests of these products including color, aroma and taste were tested on 58 respondents from different age classes showed that teenager respondents preferred herbal tea with lime aroma, adult respondents preferred jasmine aroma, while elderly respondent was very fond of original due to efficacy considerations. Antioxidant tests on these products proved that aroma additional might cause a decrease in antioxidant activity.
