Natural preservatives have been widely considered as non-synthetic materials that can prevent the biodegradation of wood due to subterranean termite attacks, namely Coptotermes curvignathus. Melia azedarach is a fast-growing species that has been widely studied for its antifeedant compounds and shows good potential to be developed as a biopesticide, especially as an anti-termite. This study aimed to identify the termicide and antifeedant properties of the wood, leaves, and bark extracts of Melia azedarach against subterranean termites and identify their bioactive compounds. The acetone extract from the three parts of the tree was fractionated. The most active fractions were selected from each part based on the percentage of termite mortality and antifeedant activity and analyzed for its bioactive compounds by pyrolysis GCMS. The ethyl acetate fraction of Melia azedarach bark exhibited strong toxic properties compared to other fractions. In the leaf section, the diethyl ether fraction showed the best termite repellent (antifeedant) properties. The anti-termite properties influenced phenolic compounds and organic acid that dominated the bark ethyl acetate fraction and leaf diethyl ether fraction. These findings show the great potential of bioactive compounds from biomaterials to be developed as a promising biopesticide. Keywords: anti-termite, bioactive compound, Melia azedarach, natural preservative

The calorific value is a parameter of palm biomass to determine its energy value. Extractives of wood is one of the factors that affect the calorific value. This study aimed to prove the positive effect of extractives on increasing calorific value by identifying the effect of adding extractives on low calorific value biomass. The study used three species wood energy, i.e., Calliandra calothyrsus, Gliricidia sepium, and Leucaena leucocephala. The soxhlet extraction was carried out to isolate extractives from sample. The calorific value sample and residue after extraction were analyzed to evaluate the changes of calorific value due to loss of extractives. The effect of extractives on the calorific value was confirmed by adding wood extractives to the palm biomass. The results showed that the extraction process reduced calorific value of residue ranging from 2.63 to 5.88%, and the bark it ranged from 5.52 to 6.70%. The addition of wood extractives to palm biomass increased the calorific value about 5.86-10.33%, while the addition of extractives from bark increase the calorific value by 6.45-9.05%. Based on the results of these studies prove that extractives have a positive effect on increasing the calorific value and can be used as an additive to increase...

Utilization of Sawdust to Produce Ethanol Using Delignification Pre-treatment with White Rot Fungi Phanerochaete chrysosporiumCurrently, Indonesia is in the middle ofpetroleum crisis. One ofthe alternative fuels which can be used as a petroleum substitute is ethanol. Ethanol can be produced from timber waste (sawdust). Indonesia in 2003 had timber waste potency of about 3-4 millions m3. However, ethanol production from sawdust has problems due to its lignin content. Therefore, research on bio-delignification treatment of sawdust prior to ethanol making process is required. In the present study ethanol was produced by simultaneous saccharification and fermentation (SSF) using crude cellulose from Trichoderma viride and Saccharomyces cerevisiae. The raw materials for ethanol production are sengon (Paraserianthes falcataria (L.) Nielsen syn.), meranti (Shorea sp.) and teak (Tectona grandis LIIVN.f.) sawdust after pretreatment with white rot fungi Phanerochaete chrysosporium for 10, 20 and 30 days incubation time. The yield of ethanol was between 1.65-44.83 g/1. The best combination treatment is sengon sawdust with 30 day incubation time.

Sifat anatomi kayu tarik dianalisis untuk parameter jumlah dan diameter pori dan korelasinya dengan komposisi lignin. Sampel kayu reaksi diambil dari batang pohon mindi (Melia azedarach) yang tumbuh miring. Pembentukan kayu tarik menurunkan jumlah dan diameter pori dan sebagai implikasinya meningkatkan proporsi serat. Jumlah dan diameter pori berkorelasi positif dengan kadar lignin. Nisbah siringil/guaiasil dan erythro/threo struktur β-O-4 berkorelasi negatif dengan jumlah dan diameter pori. Hasil penelitian ini mengkonfirmasi bahwa perubahan proporsi sel penyusun kayu akibat tegangan pertumbuhan merupakan salah satu faktor penting yang berpengaruh terhadap perubahan karakteristik kimia lignin kayu tarik. Distribution of Vessels in Tension Wood and Its Correlation with Lignin CompositionAbstractThe anatomical properties of tension wood were investigated for number and diameter of vessel and its correlation with lignin composition. Reaction wood sample was taken from the leaning stem of mindi (Melia azedarach). The formation of tension wood reduced the number and size of vessel and, consequently, increased the proportion of fiber. Number and diameter of vessels positively correlated with lignin content. However, syringyl/guaiacyl ratio of lignin and erythro/threo ratio of β-O-4 structures were negatively correlated with number and diameter of vessels. It was confirmed that changes in the proportion of wood cell was an importance factor influencing the changes in chemical characteristic of tension wood lignin.

Introduction: Lignocellulosic biomass waste will become a problem for environmental health if not managed correctly. Biomass waste decomposition can produce methane gas which impacts climate change; it can also be a source of breeding pests and diseases. Various efforts have been made to utilize the waste so that it has an added economic value and is environmentally friendly. One of the waste utilization techniques is the carbonization of lignocellulosic biomass into charcoal and liquid smoke. Discussion: A literature review used the articles from Science Direct, Pubmed, Google Scholar, and Research Gate databases over ten years. This literature review paper aims to provide information on producing and utilizing liquid smoke and concludes with some suggestions on production and application. The literature review results show evidence that liquid smoke has been used since the time of the Neanderthals. Then, since the early nineteen century, liquid smoke has been applied in agriculture as plant growth, soil treatment, pesticide, antimicrobial, rubber coagulant/deodorizer, and antioxidant. Conclusion: A significant contribution of liquid smoke utilization is all lignocellulosic biomass waste that can be carbonized into charcoal and liquid smoke so that it can reduce waste problems. Therefore, liquid smoke can reduce the use of pesticides, herbicides, and insect repellents made from synthetic chemicals that can poison the environment. Not much research has been produced and utilized liquid smoke in the pyrolysis temperature stratification technique. So, there are still quite a lot of research opportunities for the diversification of liquid smoke production.

The aqueous wood extract of bidara laut (Strychnos ligustrina) from maceration demonstrated the greatest antimalarial activity against Plasmodium falciparum strain 3D7. However, this method has several limitations, including a lengthy extraction time, which allows for microorganism contamination. The aim of this study was to quantify the yield, evaluate the antimalarial effectiveness of the P. falciparum growth in-vitro, and analyze the aqueous bidara laut heartwood extracts phytochemical composition from the two different extraction methods, namely the method of maceration extraction for 24 hours and the ultrasound-assisted extraction (UAE) for 30 (UAE30), 45 (UAE45), and 60 (UAE60) minutes. The bidara laut heartwood extract from the UAE60 method had relatively similar yield and antimalarial activity with the bidara laut heartwood extract from the UAE45 method. However, these extracts had higher yield and antimalarial activity than the extracts from the maceration and the UAE30 methods. The results of LC-MS/MS analysis revealed that the main compounds in the UAE45 and UAE60 extracts were strychnine, quinaprilat, and 3,4-bis-cyclobut-3-ene-1,2-dione, which has potent antimalarial properties. Keywords: antimalarial activity, Plasmodium falciparum, quinaprilat, strychnine, Strychnos ligustrina

Acacia auriculiformis showed good potential to be developed as a raw material for bioactive compounds. The heartwood of A. auriculiformis is still rarely explored. The purpose of this study was to identify the bioactive components of the heartwood. Six compounds were identified from the heartwood through nuclear magnetic resonance and mass spectroscopy, namely the C-3,4',7,8 hydroxyl substituted flavonoids and chalcone. Two methylated teracacidins and chalcone-like teracacidin were identified for the first time in the A. auriculiformis heartwood, along with three known compounds. These compounds showed good radical scavenging and reduction activity, compared to crude extract and ascorbic acid, using three different antioxidant assays. The molecular structure-dependent activity was observed to affect the trend of the different antioxidant activities. This finding shows good potential for further development of plant parts of A. auriculiformis from Indonesia as new raw materials for medicines. Keywords: Acacia auriculiformis, antioxidant, chalcone, flavonoid, heartwood

The fungal pretreatment effect on chemical structural and morphological changes of Betung Bamboo was evaluated based on its biomass components after being cultivated by white rot fungi, Trametes versicolor. Betung bamboo powder (15 g) was exposed to liquid inoculum of white rot fungi and incubated at 270C for 15, 30 and 45 days. The treated samples were then characterized by FT-IR spectroscopy, X-Ray diffraction and SEM-EDS analyses. Cultivation for 30 days with 5 and 10% loadings retained greater selectivity compared to that of the other treatments. FTIR spectra demonstrated that the fungus affected the decreasing of functional group quantities without changing the functional groups. The decrease in intensity at wave number of 1246 cm-1 (guaiacyl of lignin) was greater than that at wave number of 1328 cm-1 (deformation combination of syringyl and xylan) after fungal treatment. X-ray analysis showed the pretreated samples had a higher crystallinity than the untreated ones which might be due to the cleavage of amorphous fractions of cellulose. The pretreated samples have more fragile than the untreated ones confirmed by SEM. Crystalline allomorph calculated by XRD analysis showed that fungus pretreatment for 30 days has transformed triclinic structure of cellulose to monoclinic structure.
