This study aims to know the effectivity of snakehead (Channa micropeltes) gel extract on the burns healing ofrat (Mus musculus). It was carried out for 4 months, September 2018 to January 2019. The study employed anexperimental method of Complete Randomized Design with 4 treatmnets and 3 replications. Treatment A wascontrol, B used 1.5% gel extract of C. micropeltes, C used 3 %, and D used 4.5%, respectively. Results revealed thatin day-4, 8 and 12 the administration of gel extract of C. micropeltes gave significant effect on the burns healing of rat(Mus musculus) (Fcalc.> Ftab., 0.05).Keywords : gel extract, Channa micropeltes, rat Mus musculus, burns healing

Energy demand increase follow to population growth factors, high exploration costs, rising world oil prices andthe difficulty of finding sources of oil reserves. These factors cause the governments of several countries toimmediately produce alternative energy that is renewable and environmentally friendly. Wood pellets are analternative energy source. The availability of raw materials is very easy to obtain. Raw materials for wood pelletsfrom the exploitation waste such as logging residues, branches and twigs, wood industry waste such as scraps,sawdust and bark, agricultural waste such as straw and husks. Waste that is developed into a product will produce ahigher economic value. Making pellets from wood waste is an alternative energy material for meeting people's energyneeds. The opportunity to develop wood pellets as fuel is wide open because of the vast potential of forests inIndonesia and the large amount of waste from forest products, both from timber industry waste and exploitationwaste. Equipment, raw materials and the process of making pellets in a simple manner need to be socialized to thepublic so that they can be applied especially for the utilization of potential waste that can be used as raw material formaking pellets.Keywords : wood pellets, waste, simple technology, renewable energy

Rewetting program especially canal blocking (tabat) carried out by the Peat Restoration Agency (BRG) in 2017 aspart of efforts to control forest and land fires that often hit peatlands including in Kalawa Village in 2014 and 2015. Theresults of this study indicate that 7 indicators from 3 research variables for the level of land owners participation in thegroup receiving the rewetting program shows 14.28% has very strong/very high correlation (design making/constructionmodel), 42.86% has strong/high correlation (frequency of socialization, numbers of attendance, socialization method),42.86% has strong enough/high enough correlation (distance of land, placement of position/location, numbers of canalblocking). Whereas for 9 indicators from 4 research variables, the level of land owners participation in the group rejectingthe rewetting program shows 22.22% has strong/high correlation (age, land area), and 77.78% has quite strong/highenough correlation (level of education, distance of land, frequency of socialization, number of attendance, method ofsocialization, construction design/modeling, placement of position/location of canal blocking). The level of land ownersparticipation in the BRG rewetting program through canal blocking (tabat) was dominated by the medium category(36.0%) for the group receiving the program and the low category (48.0%) for the group rejecting the program. Therelatively similar characteristics of the two community groups and have a major influence on the level of land ownersparticipation are socialization efforts (frequency of socialization, numbers of attendance, socialization method), andproject implementation (design making/construction model, placement of positions/location of canal blocking).Keywords: participation; land owners; canal blocking (tabat); handel; peatland.

ABSTRACTNipa (Nypa fruticans Wurmb) is a non wood lignosellulosic materials that potential as raw material of compositeboard. One of disadvantage of the nipa fronds was contains are very high extractives and inorganic substances. Thepresence of high content of extractives in raw material of particle board potentially be an obstacle in the process ofgluing the composite board. The existing of extractive substances on the surface of the composite board raw materialscontribute to make the bonding process is not going well. On the other side, the utilization of natural binder for nonwood composite is still limited. This research focused to investigated the effects of extractive subtances for bondingperformance of natural binder such as citric acid for nipa fronds particleboard. The particles screened passed throughaperture sizes of 10 mesh and treated with three condition (non extraction, hot water extraction and n -hexanaextraction) were used as materials in this research. Addition of natural binder of 10% based on air dried particles wasdone and pressing temperature was set at 180ºC under a pressure of 3,6 MPa during 10 minutes. The physics andmechanics properties of particleboard was tested by standard JIS A 5908:2003. The results showed that theextractiction treatments for raw material affects on the properties of the particleboards. Hot water extraction treatmentwas able to give the best results. The properties of particleboard was density 0.84 g.cm-3; moisture content 7.44%;thickness swelling 1,12%; water absorption 21,83%; surface roughness 7.57 ?m; internal bonding 0.49 MPa; modulusof rupture 10.42 MPa and modulus of elasticity 3.65 GPa. All of the properties of nipa fronds particleboard meet mostof the standards JIS A 5908:2003.Keywords: Hot water extraction, n-hexane extraction, nipa frond particleboard, natural binder, citric acid.

ABSTRACTChili is one of the leading commodities of vegetables which has strategic value at national and regional levels.An unexpected increase in chili prices often results a surge of inflation and economic turmoil. Study and modeling ofchili production are needed as a planning and evaluation material for policy makers. One of the most frequently usedmethods in modeling and forecasting time series data is Autoregressive Integrated Moving Avarage (ARIMA). Theresults of ARIMA modeling on chili production data found that the data were unstationer conditions of the mean so thatmust differenced while the data on the production of small chilli carried out the stages of data transformation anddifferencing due to the unstationer of data on variants and the mean. The best ARIMA model that can be applied basedon the smallest AIC and MSE criteria for data on the amount of chili and small chilli production in Central KalimantanProvince is ARIMA (3,1,0).Keywords: modeling of chilli, forecasting of chilli, Autoregresive Integrated Moving Avarage, ARIMA, Box-Jenkins.
