Abstract

The waste of wood processing industry such as the plywood, sawmill and woodworkingindustries give waste as form of end pieces, slash, peeling residue, scrap and sawdust.The wood waste is not utilized by the furniture industry. The solution of this problem isto process these wood waste into activated charcoal. Activated charcoal can be madefrom any material containing carbon, both organic and inorganic, provided that thematerial is porous.The first,the waste wood of Ulin, Benuas, and Agathis used asmaterials in this study were carbonized and then made into activated charcoal. Thequality test of activated charcoal were yield, moisture content, ash, volatile matter, fixedcarbon, absorption of benzene, absorption of iodine and absorption of methylene blue.Overall, not all research treatments on the quality of activated charcoal fulfill to SNI 06-3730-1995. The quality of Agathis wood activated charcoal has the best quality (520,83mg/g) from all treatments by the highest score of iodine absorption (Kimia Farma (KF)standard requires >426.5 mg/g). Based on the standar of drinking water quality No.416/Menkes/Per/IX/1990, activated charcoal of agathis wood can improve the quality ofbore well water except for turbidity.Keywords: Activated charcoal, ulin, benuas, agathis, bore well water

Abstract

Humans and environment are always interaction due to they occupy the same spacebased on the rules of both interdependence and adaptation that is tied to a natural balancesystem. Human interactions have to adapt to sustain life and exploit the natural resourcesaround them that produce cultural landscapes which are inseparable from thecharacteristics area. The strong influence of nature in determining the socio-culturalconditions of humans has led to anthropogeography. In line with the rapidly increasingnumber of people including their minds are also developing science and technology toobtain the necessary of their life. Humans have not a sense of being part of the socio-biogeophysical system, but are separate and stand outside of its and produceanthropocentrism. These phenomena have produced the idea that have to be aharmonious and balanced relationship between human necessary and the naturalresources capability. This means that human has to recognize their survival and otherspecies depend on ecological principles. Thus, human necessary should be carried out inan integrated with the other species necessary that produce an ecocentrism that respect tonature.Keywords: Human, environment, interaction, anthropocentrism, anthropogeography,ecocentrism

Abstract

The Indonesian Selective Cutting and Planting Silvicultural System (ISCP) has beenapplied to manage natural production forests since 1989. This system was revised in1993 and 2009. This study aims to determine the condition of natural forests afterlogging at PT Bina Multi Alam Lestari, Central Kalimantan Province. The study wasconducted using the plotted plot method proportionally in P-8 Block of RKTUPHHKHA at 2021. The results showed that the structure and composition of the vegetation inthe forest after being harvested using the TPTI silvicultural system at PT Bina MultiAlam Lestari was still well maintained. The meranti tree group dominated the tree levelbefore and after harvesting with INPs of 141 and 135.56, respectively, as well as for thepole level with INPs of 108.56 and 106.33, respectively. Meanwhile, at the seedling andsapling levels, other commercial groups (non dipterocarps) were dominated. Speciesdiversity are high with a range of values of H' 3.1 to 3.3 and species richness rangedfrom moderate to high with a range of values from 3.94 to 6.68. The level of vegetationdensity is still well maintained and is above the standards set by the Ministry ofEnvironment and Forestry. The distribution of vegetation diameter in the forest beforeand after harvesting still resembles the condition of mixed natural forest (unaged standforest) with an inverted J pattern. Natural forest harvesting activities using the TPTIsilvicultural system at PT Bina Multi Alam Lestari in the RKTUPHHK-HA Block in2021 did not cause significant damage and environmental conditions are still wellmaintained.Keywords: Natural forest, Important Value Index, diversity, richness, density

Abstract

Seed gardens are one way to obtain quality seeds. Seed gardens are areas where certainplants are planted to produce seeds of superior genetic origin. The seed garden of TheUniversity of Palangkaraya in maintaining red meranti (Shorea leprosula Miq) plantsencountered several obstacles, one of which was pests and diseases. Identification of pestand disease attacks is basically the beginning to find out a plant needs special care orattention to improve the quality of the plant itself. This study aims to identify anddetermine the intensity of pest and disease attacks on red meranti (Shorea leprosula Miq)in the seed garden area of The University of Palangka Raya. Collecting data using thecircle plot method, a systematic random sampling technique. Based on the research, it wasfound that the types of pests and diseases that attack red meranti are fire caterpillar(Setothosea asigna), beetle (Mecynorrhina sp), leaf spot (Curvularia sp and Nigrosporasp). The frequency of pest attack is 7.52% and the intensity of attack is 0.75%, with acombination frequency of 1.50% and an attack intensity of 0.45%.Keywords: identification, pests, diseases, seed garden
