Abstract

Istilah “energi baru dan terbarukan” disebut sebagai solusi dari ketergantungan akan sumber daya alam yang tidak dapat diperbarui dalam krisis energi. Wood pellet merupakan salah satu bentuk produk yang dapat dikembangkan sebagai alternatif sumber energi baru. Wood pellet biasanya memiliki diameter antara 3 - 12 mm dan panjang bervariasi antara 6 – 25 mm. Tujuan penelitian ini adalah untuk mengetahui pengaruh peningkatan ukuran serbuk terhadap kualitas wood pellet serta mengetahui pengaruh pemakaian perekat tapioka dan sagu terhadap kualitas wood pellet. Manfaat penelitian ini diharapkan dapat meningkatkan nilai tambah limbah kayu jati dan memberi informasi ilmiah baru dalam pengembangan bahan baku teknologi pelleting mengacu pada Standar Indonesia, Austria, Jerman dan Swedia.Penelitian ini menggunakan bahan baku limbah serbuk gergajian kayu jati (Tectona grandis). Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap dengan 2 faktor perlakuan yaitu ukuran serbuk dan jenis jenis perekat. Parameter yang diamati dalam penelitian adalah rendemen, kadar air, kerapatan, berat jenis, kadar abu, karbon terikat dan nilai kalor wood pellet. Hasil penelitian menunjukkan jenis perekat dan ukuran serbuk tidak berpengaruh nyata terhadap nilai kadar air, kadar abu, karbon terikat, dan nilai kalor begitu juga dengan interaksi kedua faktor tersebut. Namun, jenis perekat dan ukuran serbuk berpengaruh sangat nyata terhadap nilai kerapatan dan berat jenis. Faktor ukuran serbuk serta interaksi kedua faktor berpengaruh nyata terhadap nilai rendemen. Penggunaan perekat tapioka memiliki kerapatan wood pellet lebih tinggi daripada perekat sagu yaitu 0,842 g/cm3 dan 0.803 g/cm3, serta penggunaan perekat tapioka juga memiliki berat jenis wood pellet lebih tinggi daripada perekat sagu yaitu 0,762 dan 0,725. Ukuran serbuk yang semakin halus memberikan kerapatan dan berat jenis Wood Pellet yang semakin tinggi dengan nilai sebesar 0,852 g/cm3 dan 0,769. Interaksi jenis perekat dan ukuran serbuk berpengaruh nyata terhadap nilai rendemen yaitu 41,578 – 48,667 %. Secara umum, hasil penelitian ini lebih banyak diterima oleh standar Indonesia dan Jerman dibandingkan standar Austria dan Swedia. Hasil penelitian terbaik yaitu wood pellet ukuran 40-60 mesh dengan menggunakan perekat tapioka dengan nilai kalor 4399,638 kal/g.

Abstract

Many types of soil born fungi associate mutually with high-level plant roots by forming mycorrhiza. While fruit body characterization was used previously, now molecular method wide used to identify ectomycorrhizal fungi when faces discontinuity fruit body presented on the floor and the important of identifying ectomycorrhizal fungi that lignning in particular association.Hence, the purpose of research is to identify the ectomycorrhizal fungi associated with dipterocarp species using moleculer method. Polymerase Chain Reaction (PCR) technique was conducted on DNA extract samples from root tips of dipterocarp trees and 3 (three) Shorea (S. leprosula, S. stenoptera, and S. mecistopteryx) seedlings intentionally planted under mature trees. DNA sequences were amplified using a specific primer pair of fungus and basidiomycetes ITS 1F-ITS 4B. The identity of ectomycorrhizal fungi was obtained by matching DNA sequence of the samples to Genbank database. Molecular identification resulted in 73 genotypes that belong to 13 families, i.e Thelephoraceae, Russulaceae, Clavulinaceae, Sebacinaceae, Inocyabaceae, Amanitaceae, Entolomataceae, Heliotialetaceae, Boletaceae, Cantharellales, Hymenogastraceae, Ceratobasidiceae, and Tricholomataceae. Thelephoraceae consists of 54 genotypes, Russulaceae and Sebacinaceae 13 genotypes, Clavulinaceae 6 genotypes, and the rest consist of 1-3 genotypes. Thelephoraceae is the dominant family in ectomycorrhizal jamurcommunities. Based on the results, it can be concluded that molecular method can be used to identify the real symbiont in mycorrhiza association. In addition, molecular methods can also detect the similarity of ectomycorrhizal fungi that colonizing dipterocarps, both at trees and seedlings level.

Abstract

Teak is a high value wood. The tree trunk has a high economic value because it provides multipurpose wood products. Tree trunks have distinctive biometric characteristics, including teak trunks. The biometric characteristic of a tree species is a problem in the science of forest planning, because the growth of tree trunks is influenced by many factors, including differences in age, location and site. This research will be arranged biometric model of teak tree that grows in Batulanteh Forest Management Unit, beginning with collecting physical data of tree through measurement of tree dimension. This study uses 75 sample trees grown in the Batulanteh Forest Management Unit area. The data used were tested outlier with boxplot method and calculated ratio and correlation. The regression equation was done by using SPSS version 23 program. Different ratios between tree dimensions at different ages were tested using complete randomized design. The results of this study indicate that the growth model of base diameter, diameter at breast height, and total height are characteristic of trees that are highly correlated with other tree biometrics characteristics. So in the management of teak forests Batulanteh Forest Management Unit can make these three characteristics as a reference in looking at the characteristics of other trees. The results also show the ratio Dp / Dbh, Tt / Dbh still fluctuate throughout the age of 10 to 22 years. Keywords : Teak, growth model, inter-dimensional ratio, age

Abstract

Global warming is happened cause by prolonged drought, forest fires, floods and landslides. High carbon emissions from industries, burning of forests and peatlands exacerbate these conditions. Excessive gas emission has the potential to be a barrier to the reflection of infrared rays from the earth into the atmosphere and it has a warming effect, which is then called the greenhouse effect. Wood is one of the plants that have extractive components that can absorb carbon emissions most effectively. The study aims to determine the extractive components of sengon and johar wood that can capture formaldehyde emissions. The research design used a one-factor Complete Randomized Design, namely the type of sengon wood and johar wood with analyzed using the SPSS program. The parameters observed were specific gravity, extractive content and formaldehyde emission. The results showed that sengon and johar wood types had different specific gravity, extractive content and formaldehyde emission. The average density of sengon wood is 0,236, extractive which is soluble in cold water 3,653%, in hot water 4,158%, soluble alcohol bensen 3,660%, and formaldehyde emission 0,927 ppm. The average density of johar wood is 0.650, extractive which is soluble in cold water 5.020%, in hot water 8.740%, soluble alcohol bensen 10.310% and formaldehyde emission 0.473 ppm. Extractive components that play an important role in absorbing carbon emissions are extractive components that dissolve in cold water and hot water, where the extractive component contains polar organic compounds, such as sugar, dyes, tannin, gum, protein and starch. Keywords: Extractive, global warming, formaldehyde emissions
