Abstract

This research aims to estimate the biomass, carbon storage, carbon dioxide uptake and oxygen produced by sengon (Paraserianthes falcataria (L.) Nielsen) stand aged 9, 11 and 13 years in IUPHHK-HTI PT Parwata Rimba, Central Kalimantan. Estimated of biomass, carbon stock, CO2 uptake and Oxygen produced using allometric equations. The results showed that the storage of sengon standing biomass aged 9,11 and 13 years ranged from 110.71 to 200.94 tons/ha, carbon stock ranged from 52.03 to 94.44 tons C/ha, CO2 uptake ranged from 190.79 to 259.13 tons CO2/ha and Oxygen produced around 138.75 to 251.84 tons O2/ha. The total of biomass, carbon stock, CO2 uptake and Oxygenproduced by sengon stands at forest plantations are large enough to have an important role in global climate change mitigation in the forestry sector.

Abstract

Tumih wood (Combretocarpus rotundatus (Miq.) Danser) is classified as an unknown type of wood which is widely grown in peat swamp forests in Central Kalimantan. This study aims to analyze the physical properties and mechanical properties of wood in axial and radial directions so that they can be utilized properly. The results of the study resulted in fresh water content and dry air content of wood air, each of which was 71,58% and 19,33%, kiln dry weight 0,72, tangential shrinkage 9,68%, radial shrinkage 5,02% and longitudinal shrinkage 0,19%. Testing of mechanical properties resulted in a flexural firmness of 618,33 kg/cm2, compressive strength parallel to the fiber 333,27kg/cm2, shear constancy 92,02 kg/cm2, hardness 355,60 kg/cm2, and stiffness at 19,50kg/cm2. Based on the Indonesian Wood Construction Regulations Standard (PKKI) NI 5-1961 tumih wood is included as a strong class III of Indonesian wood, so it is quite well used for home building raw materials, beams, floor and wall boards, door/window frames, and furniture.

Abstract

Deforestation rates on Kalimantan Island from 1990 to 2014 were recorded at 1.12% (± 0.36 million hectares) each year. Central Kalimantan has a forest decline rate of 1.36%. Land cover changes are important information in the management of forest areas. Changes in land cover are important information in the management of forest areas. This study was carried out throughout the Peat Hydrological Unit (PMU) in Central Kalimantan Province as many as 35 PMU with an area of 4,671,558 Ha. The method used is a quantitative method using ArcGIS 10.1 and Microsoft Excel software for dataanalysis. The data used are Land Cover Map Data in Central Kalimantan in 2016-2017, City/District Administration Area Map and Central Kalimantan Provincial Spatial Planning Map. The results obtained are Deforestation and Degradation in 2016 - 2017 occurred in 75% of the Peat Hydrological Unit Area in Central Kalimantan, in all spatial patterns in the PMU and in all district / city administrative areas

Abstract

Plantation of jelutung rawa (Diera lowii) project has been conducted by many local peoples, aspecialy at the Pulang Pisau District, Central Kalimantan. The purpose of this research was to analyze the growth of Jelutung rawa (Diera lowii) at the Peat Swamp Land in Pulang Pisau District, Cetral Kalimantan. The research was conducted at Jabiren Village, Pulang Pisau Disttrict, Central Kalimantan start from July to September 2019. Researct result showed that mean annual increment (MAI)-diameters of jelutung rawa at 4, 6, 7, 10, 12 dan 13 years old namely 2.52 cm-2, 2.52 cm-2, 2.80 cm-2, 2.22 cm2 , 2,14 cm-2 and 2,02 cm-2 respectively. Meanwhile, at the same of ages, height of jelutung rawa namely 4.88 m, 6.50 m, 10.84 m, 11.29 m, 16.17 m, and 19.30 m respectively. Polynomial growth model of jelutung rawa for their diameter and height are y = - 3.825941 + 4.1244995x + (-0.140316) x 2 and y = 3.562047 + 0.212857x + 0.72187x2 respectively with coefficient of determination namely 62% and 82% respectively.

Abstract

The production volume or amount of Acacia wood used is generally low compared to the volume of wood harvested. Not a few woods that are cut cause wood harvesting waste such as branches and twigs. One of the uses is processing the waste into activated charcoal. Activated charcoal is charcoal whose cavities or pores are cleaned from other compounds so that the adsorption power of liquids and gases increases. This research uses the Acacia wood of the stem, branches and twigs which is first through the carbonization process and then used as activated charcoal. The active charcoal testsinclude yield, moisture content, volatile matter content, ash content, carbon bound content, absorption of benzene, absorption of iodine and absorption of methylene blue. Acacia quality test results of the stem, branches and twigs show that the activated charcoal of the stem has better quality than the active charcoal of branches and twigs. Overall the results of testing the quality of activated charcoal not all treatments meet the requirements of SNI 06-3730-1995, but when compared with the requirements of the quality of pharmaceutical chemistry, all tests for each treatment meet the quality standard requirements. The application of activated charcoal to drilled well water does not all improve water quality but still qualifies the drinking water quality standards Minister of Health Regulation No: 416/Menkes/Per/IX /1990.

Abstract

Proses pewarnaan rotan dilakukan dengan menggunakan dua jenis tanah sebagai media perendaman yaitu tanah lempung yang diperoleh dari desa Gohong Kabupaten Kahayan Hilir dan tanah berpasir yang ada di kota Palangka Raya. Pengenalan daun tepanggang sebagai pewarna alami yang aman bagi kesehatan dan lingkungan, mampu memberikan variasi warna yang menarik untuk mengembangkan berbagai motif desain anyaman rotan terutama bagi perajin anyaman rotan yang dijadikan mitra yaitu Duta Dare. Tujuan penulisan ini adalah membandingkan dua jenis tanah yaitu lempung dan pasir sebagai media perendaman rotan yang terlebih dahulu direbus dengan daun tepanggang, sehingga menghasilkan produk yang mampu bersaing dengan berbagai modifikasi tren warna masa kini dengan nilai jual yang tinggi. Metode pelaksanaan melalui penyampaian materi, Tanya jawab, praktek langsung bersama mitra, dan melakukan evaluasi terhadap hasil kegiatan. Pewarnaan rotan direndam dengan tanah lempung menghasilkan warna hitam mengkilap, sedangkan perlakuan dengan tanah pasir menghasilkan rotan dengan warna abu-abu yang tidak menarik.Kata Kunci: Tanah, pewarnaan rotan, anyaman rotan
