Abstract

ABSTRACT Wood waste is biomass waste from wood cutting and the waste of the production process of the wood processing industry. Waste can be seen as a form of output side of a production process which often do not have economic value (unuse). Charcoal briquettes can be developed the waste biomass utility. This study aims is to determine the physical-mhanical properties of charcoal briquettes produced from the raw material of wood charcoal of plywood industrial waste (waste stripping finir) and waste of indutry plantation forest (HTI) from top/end section. Physical-mechanical properties of charcoal briquettes of this research qualify to the general requirements of the charcoal Indonesia quality (SNI 01-6235-2000). Keynotes: Charcoal briquette, waste, wood

Abstract

ABSTRACT Exploiting the potential and diversity of types of peat swamp forest is not known (lesser known species) both types of timber and non-timber forest products, needs to be done to anticipate the reduction in the availability of commercial timber is to alternatively manufacture of cement particle board. As an alternative building materials manufacture of particle board has good prospects, given the increasing need tehadap shelter each year. Selection of wood types mahang as many grown on peat swamp forest in Central Kalimantan and nature meet the criteria of wood as raw material for cement particle board and supported by the manufacturing process is quite easy. The study aims to determine the effect of particle size and the ratio of adhesive cement with wooden particles mahang against mechanical and physical properties of particles produced cement board, and can determine the quality of the cement particle boards that meet the requirements of building materials. Based on the terms of quality of cement board wood patikel mahang produced, including a group of cement particle board type III (> 0,6 g / cm3), medium density of 0,40 g/cm3 - 0,80 g/cm3, and including cement particle boards used for wall with a specific gravity of 0,70 to 0,90. Based on the terms of raw material utilization efficiency of wood mahang then recommended a combination treatment a1b1 (the weight ratio of the amount of cement with particles 1: 1,5 and small particle size) produces cement particle board that filled the finest wood standard. Research advanced mechanical properties of cement particle board of wood to meet the internal bond (kg/cm2) and a strong grasp of the screw (kg). Keywords: wood particle mahang, cement, physics and mechanical properties of cement particle board

Abstract

ABSTRACK The aim of this study to known influence land use change in low tide and ombrotrophic peatland on forest land, ex-burns land, rubber tree land, and maize land and to known amount of microbial populations there. Data was recorded automatically by some equipments are chamber, Infrared CO2 analyzer (Fuji ZFP9GC11), injection 200 cc, Soda Lime, Vacuum plastic, Vacuum oven, termometer, FDR ML 2 Theta Probe Delta Y Device Co, Sensor water table, Lux meter, meter, camera, and paper label. Observation method was carried out at the village Kalampangan (ombrotrophic peatland) , district of Sebangau, Palangka Raya city, and at the village Purwodadi (low tide peatland), district of Maliku, Pulang Pisau Regency, starting from May up to July 2014. Observation variables consist of CO2 fluxes, fluctuations of groundwater levels, soil temperature, soil humidity and microbial populations. The results show that overall carbon dioxide fluxes higher in low tide peatland, with the highest fluxes in burnt areas, 430.24 mg C m-2 h-1, whereas in Ombrotrophic peatland, the highest on 292 forested land, 92 mg C m-2h-1. In Ombrotrophic peatland, relation between fluxes of carbon dioxide and the soil temperature is significant in the burnt areas with a value of R = 0.856 with a quadratic pattern, with the average temperature of 28.89 ° C. Fluxes of carbon dioxide significantly effected by soil moisture that is at a rubber plantation with a value of R = 0.640 with quadraticpatterned, average soil moisture of 0.61 m3/m-3. Fluxes of carbon dioxide to the groundwater depth is significant on a rubber plantation with a value of R = 0.872 with a quadratic pattern, and depth of groundwater on average of 83.74 cm. The populatuin of microorganisms, in forest land 137 sel/ml, rubber plantations 154 sel/ml, cornfields 157 sel/ml and ex-burnt is 80 sel/ml. In Low Tide peatland, fluxes of carbon dioxide to the soil temperature is significant in forest land with the value of R = 0.545 with cubic pattern, and the average temperature of 27,39 oC. Soil moisture has the siginificant effect to fluxes of carbon dioxide that is in the burnt areas with a value of R = 0.617 with patterned quadratic, and average soil moisture of 0.50 m3/m-3. The ground water depth has a siginificant effect to fluxes of carbon dioxide in a cornfield with a value of R = 0.743 with a quadratic pattern, and the depth of soil water on average of 68.98 cm. Population of soil microorganisms, in forest land 73 sel/ml, rubber plantations 36 sel/ml, cornfields 51 sel/ml and ex-burnt 18 sel/ml. Soil temperature, soil moisture, groundwater depth and microoganisms effect on carbon dioxide fluxes. Key words: Carbon dioxide, fluxes, microorganisms, peatland

Abstract

ABSTRAK Pengetahuan masyarakat lokal akan pemanfaatan jamur baik sebagai jamur obat maupun jamur pangan masih belum memadai serta informasi yang berkaitan dengan pemanfaatan jamur masih dirasakan kurang sehingga potensi jamur yang seharusnya dapat mendukung peningkatan kesejahteraan hidup juga tidak dapat dirasakan oleh masyarakat. Tujuan penelitian ini adalah mengetahui keragaman jenis jamur Basidiomycota yang berpotensi sebagai jamur obat serta jamur yang dapat dikonsumsi (bahan pangan) bagi masyarakat lokal. Metode yang digunakan dalam penelitian ini adalah dengan melakukan orientasi lapangan dan penentuan lokasi penelitian kemudian membuat plot penelitian dengan ukuran plot 200 x 150 m atau 3 ha sebanyak satu 1 buah. Pada plot tersebut dibuat jalur pengamatan jamur sebanyak 8 jalur, jarak antar jalur adalah 5 m dan lebar jalur 20 m. Plot penelitian ini dibuat di masing-masing desa lokasi penelitian. Selanjutnya dilakukan eksplorasi jenis jamur, koleksi dan identifikasi jenis jamur yang terdapat di hutan alam di kedua desa serta melakukan wawancara dengan masyarakat lokal mengenai pengenalan dan pemanfatan jamur. Hasil penelitian diperoleh 7 famili dan 46 jenis jamur Badisiomycetes di hutan alam desa Bawan, jamur yang dominan adalah Ganoderma sp dari famili Ganodermataceae sedangkan di desa Ramang ditemukan 8 famili dan 36 jenis jamur Basidiomycetes dengan jamur yang mendominasi adalah jenis Trametes versicolor dari famili Polyporaceae. Berdasarkan informasi dari masyarakat lokal tidak banyak ditemukan jenis jamur pangan dan jamur yang dapat dimanfaatkan sebagai obat. Terdapat 2 jenis yang sering dikonsumsi oleh masyarakat local yaitu jamur kuping (Auricularia delicate) dan jamur tiram (Pleurotus sp.) serta jamur yang dapat digunakan sebagai obat adalah jamur Ganoderma lucidum, sementara jenis jamur lain yang ditemukan sebagian belum dapat diidentifikasi, namun sebagian lagi termasuk jamur parasit dan jamur beracun. Kata kunci: Biodiversitas, Basidiomycetes, Biobanking

Abstract

ABSTRACT The local table of volume is needed to determine volume of stands just based on their diameters in the certain of region. The research was aimed to create the local table of volume based on three groups of trees, namely Shorea groups, Dipterocarp non Shorea groups, and non Dipterocarp groups. Location of research was in Sub-District of Kapuas Hulu and Mandau Talawang, District of Kapuas, Central Kalimantan Province. Research method using tabel of volume equations in the form of Berkhout model that in order of regression equations. Research result showed that table of volume to Shorea groups, Dipterocarp non Shorea groups, and non Dipterocarp groups on the those two sub-districts are V = 0.00012D2.549, V = 0.000172D2.4319, and V = 0.00009D2.6292 respectively. According to the F test and R2 value, the local tables of volume are suitable used to predict the volume of the stands in the sites and their surrounding. Keywords: Dipterocarp, regression, shorea, table of volume.
