Wood is potential biomass with various benefits such as is utilizing them for liquid smoke raw material. Consequently, research on liquid smoke by pyrolysis should be conducted intensively to gain necessary information on the active content and utilization of the liquid smoke. This research is aimed to determine characteristics and potential utilization of liquid smoke made from trema, nani, merbau, matoa and malas wood. Research was conducted by pyrolysis process at 500°C for 5 hours and the liquid smoke was collected in container for analyzes. Analysis of liquid smoke characteristics included pH, specific gravity, acetic acid, phenol and other chemical component content using py-GCMS. The result showed that the pH ranged from 2.68 to 4.34, specific gravity ranged from 0.83 to 1.04, acetate 0.65-13.09%, and phenol content 0.19-2.50%. GCMS analysis showed chemical component diversity and its main component as identity of specific liquid smoke from five wood species confirmed were acetic acid (acetic acid, ethylic acid), phenolic (phenol, 2,6-dimethoxy (CAS) 2,6-dimethoxyphenol), and carbamic acid. The chemical component of liquid smoke is expected to be applied in wide variety of products based on product's perspective, objectives and product targets that would be achieved.
Research of liquid smoke from 3 species of bamboo has been conducted by using modified drum furnace. The purpose of this study is to determine the chemical components and other properties of liquid smoke. The results showed that the yield of liquid smoke 3 types of bamboo ranged from 5.00 to 24.00%, a pH of 2.70 to 3.36 has been standardized Japan; gravity of 0.99 to 1.03, acetic acid 31.37-83.59%, from 1.37 to 2.07% methanol and 0.56 to 1.24% total phenol. Acetic acid, methanol and total phenol liquid smoke test results of black bamboo has the highest value, followed by liquid smoke and spotted bamboo lowest in the liquid smoke bamboo betung.
Teak (Tectona grandis) is one of the high-quality wood-producing trees. Large trees, straight trunk, large leafy, with the height reach 30-40 m. The nature and characteristics of teak trees usually drop their leaves every dry season, and this will cause problems for the surrounding community because the dry leaves fall into waste and have not been utilized properly. Waste of dried teak leaves will accumulate under the stands of teak trees, and in the dry season can be a trigger for forest fires. the teak leaves contain 48.51% bounded carbon, 6.61% moisture content, 31.72% ash content, 13.17% volatile content, and density 0.65 g/cm. In addition, teak leaves also contain flavonoid compounds, protein, nine phenolic acid or tannin compounds as well as crude fiber content covered in lignin of 22.9. Based on the content in the dry teak leaf litter waste, this paper presents an effort to use it into a number of useful products, one of which is the utilization of dry teak leaf litter waste for liquid smoke, and several other uses carried out by communities around the teak forest such as for charcoal briquettes, compost, medicine, and animal feed. Analysis of liquid smoke was carried out at the Integrated Laboratory of the Forest Products Research and Development Center using the Pyrolysis GCMS method. Meanwhile, other results are a review of several studies conducted by the community.
Beberapa tanaman seperti kakao (Theobroma cacao), alpukat (Persea americana), puspa (Schima wallichii), sengon (Falcataria mollucana) dan tarik angin (Usnea sp.) banyak ditanam di masyarakat untuk kebutuhan buah-buahan atau kayu. Secara periodik, masyarakat memanen jenis-jenis tersebut untuk dimanfaatkan kayunya atau peremajaan tanaman. Pada umumnya, sortimen kayu digunakan untuk konstruksi sederhana, atau dibakar. Selain teknik pembakaran konvensional untuk menghasilkan arang, ada produk lain yang dapat dihasilkan yaitu asap cair menggunakan teknik pembakaran dengan menambahkan kondensor untuk menghasilkan asap cair. Asap cair memiliki kandungan kimia organik dengan beragam manfaat. Studi ini bertujuan untuk menganalisis kandungan kimia organik jenis asap cair dari jenis kayu kakao, kayu alpukat, kayu puspa, kayu sengon dan kayu tarik angin. Kelima jenis material studi dikarbonisasi menggunakan reaktor pirolisis pada suhu 400°C. Asap cair didapat dengan cara kondensasi uap karbonisasi kelima jenis tersebut. Analisis kandungan kimia organik asap cair menggunakan kromatografi gas-spektrometer massa (Gas Chromatography Mass Spektophotometry, GCMS) Pirolisys Type QP2010 dan High Performance Liquid Chromatography (HPLC). Analisis GCMS menunjukkan bahwa asap cair kayu kakao memiliki konsentrasi kelompok asam tertinggi, yaitu 45,53%, sementara konsentrasi asam asetatnya adalah 31,81%. Kehadiran kelompok fenol tertinggi terdapat pada asap cair kayu alpukat sebanyak 56,86%, di mana konsentrasi senyawa fenol mencapai 41,92%. Kelompok asam dan fenol merupakan jenis senyawa yang terkandung pada asap cair dan memiliki manfaat yang luas.
