Tropical peat swamp forest (PSF) has a high species diversity and value including timber value. The valuation of timber is approached by calculating the stand volume. However, the volume model at PSF is not available for every species and species groups in specific site. This study aims to obtain a volume estimation model of species groups of tree species in peat swamp forest in Central Kalimantan. The model development and validation used 120 sample trees of the dipterocarpaceae and non-dipterocarpacae species. The distribution of sample trees is 70 % for the development model and 30 % for the validation stage. Modeling used linear and non-linear models). The selection of the best model used several criteria including: coefficient of determination, relative deviation (SR <8 %) and aggregation (SA <1 %), presumptive bias (s and RSE: Root Square Errors), AIC (Akaike's Information criteriation), and NRMSE (Normalized Root Mean Square Errors). The results of this study indicated the Berkhout/diameter model as a single variable was very good in estimating the volume of trees at all levels namely species groups and all species except dipterocarpaceae groups. This model had a high coefficient of determination (R2 >95 %). The models compiled met the SA and SR criteria so that the models were very accurate in estimating tree volume at the tree level, as individuals and stands. The implication of this research was that the whole species model can be used to estimate the volume of trees in peat swamp forest.Keywords: accuracy, timber , non-linear, validation

Nyamplung (Calophyllum inophyllum L.) is one of forestry plant that has double benefits (economic and ecological). One of the problems faced in the development of nyamplung is its recalcitrant seed, which can not be stored for long periods. To increase the viability of nyamplung seed during storage, seed invigoration techniques are required. Invigoration is the treatment given to seeds before planting with the aim of improving germination and growth of sprouts. The purpose of this research is to know the proper invigoration technique on nyamplung seed during storage. The experimental design of the research was used Completely Randomized Design (CRDL) with factorial. There are 2 factors treatments: the first factor of: Invigoration treatment (control, osmoconditioning with soaking in aquades for 24 hours, osmoconditioning with immersion in PEG-6000 concentration 15 % for 24 hours, matriconditioning with moisture of newspaper (CD) for 2 hours, and matriconditioning with moisture ash scrub for 2 hours) and savings period factor the second factor of period of storage (0, 1, and 2 months). The research was conducted with replication is 4 times, @ each with 50 seeds of seed. The observation of germination is done after normal sprout growth, which it has of a pair of leaves. The parameters observed were germination and germination rate. The results showed that the proper invigoration technique on nyamplung seed during storage was the treatment of matriconditioning with moisture of newspaper (CD) for 2 hours. With this treatment it can increase the viability of seed nyamplung (germination) at 42 % and vigor seed (germination rate) at 0,56 % /etmal. results at the end of the abstract. The longer the storage period will cause the value of germination and the speed of germination to decrease.Keywords: seed, invigoration, nyamplung (Calophyllum inophyllum L.), recalcitrant, viabil

Belitong Island, The Province of Bangka Belitung is one of the exotic places with the biodiversity which has not been optimally inventoried. One of the potential germplasm that has not been recorded properly on Belitong Island is the mushrooms diversity and their potential uses. Mushroom are known as non-timber forestry product that is often sought after by local ethnic of Belitong Island and used as food. Apart from being consumed, these wild mushrooms are also traded, so they are one of the important seasonal commodities for the local community. This research aimed to provide the basic taxonomical information of wild edible mushroom in Belitong island as well as the biological characters. Observations were conducted 2 times in 2018 – 2019 using opportunistic sampling method. The utilization data of wild edible mushroom were collected to complete the macrofungi description in this study. A number of 5 edible wild mushrooms with th economic value reported in this study were: Amanita sect. caesarea (kulat pelandok), Heimioporus sp. (kulat pelawan), Hygrocybe cf. conica (kulat tiong), Phylloporus sp. (kulat sukatan) and Volvariella sp. (kulat sawit). Three species of fungi are ectomycorrhizal forming fungi, namely kulat pelandok with Schima wallichii, kulat pelawan with Tristaniopsis merguensis, and kulat sukatan which host is still unclear. Meanwhile the rest are saprophytic macrofungi. All wild edible mushrooms are members of the phylum Basidiomycota which are divided into 2 orders and 4 families. Heimioporus sp. is known to be the highest selling price mushroom compared to the others, which indicated the potential prospect to proceed to the cultivation stage. In addition, conservation management of plants that are hosts of ectomycorrhizal fungi need to be an important concern on Belitong Island.

Combo nursery technique is a technique where seedlings/cuttings of Shorea leprosula, Gliricidia sepium, and Brachiaria decumbens grass were planted in one polybag to support mining reclamation. To reduce competition effects among the three species, optimum media and size of polybag need to be investigated. The objective of this experiment is to analyse the effect of size of polybag and media composition on the growth of S. leprosula, G. sepium, and B. decumbens grass in the combo nursery technique. The experiment used Randomised Complete Design in Factorial with two factors, i.e. media compositions (soil : compost (2 : 1, v/v), (1 : 1, v/v), (1 : 2, v/v), and soil : compost : rice husk (7:3:1, v/v/v); and size of polybag (15 x 20 cm, 20 x 20 cm, dan 25 x 25 cm). Each treatment had four replications, and each replication consisted of four polybags. The results showed no significant interaction effects between the composition of media and the size of polybag; however, media compositions of soil: compost (1:1) and (1:2), and the sizes of polybag 20 x 20 cm and 25 x 25 cm significantly eliminated competition and significantly increased the growth of S. leprosula and the number of tiller of B. decumbens grass.Keywords: Brachiaria decumbens, Gliricidia sepium, mining reclamation, nursery, Shorea leprosula

Fulfillment the needs of Red Jabon (Anthocephalus macrophyllus (Roxb.) Havil) seeds on the other hand can create an unbalanced ecosystem. The availability of red Jabon seed was becoming a source of food for pests, then it causes an explosion of pests and pathogens. The disease that most often affect red Jabon seeds, both in the nursery and in the field was red leaf spot (antraknose). The initial step to control red leaf spot disease is the identification of causing. Identification method performed by observation of the symptoms in the field, followed by microscopic observation in a laboratory. Based on the identification result, it was known that the disease caused by the fungus Cercospora sp., Colletotrichum sp. and Pestalotia sp. The effect caused by those fungal pathogens was the disruption of the photosynthetic process that ultimately inhibits the growth of red Jabon seeds. The controls which have been done are arranged the watering intensity, isolated the infected seed,and applied the chemical fungicide.

Forest fires are one of the environmental problems that recur almost every year in Indonesia. This problem if not handled properly will certainly cause various negative impacts such as the emergence of haze that can interfere with public health and reduced forest cover, in forest areas. Taman Hutan Raya Nipa-Nipa (Tahura) as one of the Natural Preservation areas of Southeast Sulawesi Province is also inseparable from the problem of forest fires. The aims of the study were to analyze the level of forest fire vulnerability in the Tahura Nipa-Nipa area, especially in Watu-Watu Village, West Kendari Subdistrict, and the variables that most affect the level of forest fire vulnerability. Data analysis based on the weighting of each element is then carried out the determination of the vulnerability class using equations: forest fire vulnerability = {30 % x (land cover)} + {(20 % x height of place)} + {(20 % x Rainfall)} + {(10 % x distance from road)} + {(10 % x distance from river)} + {(10 % x distance from settlement)}. Mapping the class of forest fire vulnerability areas using geoprocessing with input data on land cover, place height, rainfall, and distance from roads, rivers, and settlements. Then an analysis is carried out and will be selected data according to the score of the level of forest fire vulnerability, namely very low/not a vulnerability with a score of 5, low with a score of 4, medium with a score of 3, high with a score of 2, very high /very vulnerability with a score of 1. The results showed that the level of forest fire vulnerability in Tahura Nipa-Nipa has 3 levels, namely the level of high forest fire vulnerability with an area of 68.51 ha, the level of moderate forest fire vulnerability with an area of 62.29 ha, and the level of low fire vulnerability with an area of 143.35 ha. The variables that most affect the level of forest fire vulnerability at the research site are land cover and community accessibility distance in the form of distance from the road and distance from the settlement.
