This study aimed to investigate the use of water hyacinth to produce liquid smoke. The study observes the temperature and time variables of yield, pH, density, and refractive index in the production of liquid smoke from water hyacinth. The sequence of the work is as follows: first, water hyacinth was cut into 5 cm sections and then sun-dried for 2–3 d, depending on the weather. Next, 550 g of dried water hyacinth was added to the pyrolysis reactor. The temperature variations were 200°C, 400°C, and 600°C, and the time variations were 1, 4, and 7 h. As a result, liquid smoke was produced with varying yield, pH, densities, and refractive indices. The best results in this research are liquid smoke pyrolysis at a temperature of 400°C and 4 h with the acquisition of a yield of 93 mL, pH 2–4, a density of 1.080,8 gr/mL, and a refractive index of 1.339,6, with chemical component 41.45% total acid, 2.44% phenol and 56.10% carbonyl.

“…Lignocellulosic biomass decomposition by pyrolysis method produces bio-oil, which can be applied as a biopesticide. The chemical components of bio-oil resulting from lignocellulosic pyrolysis are ammonia, hexane, alcohol, ketone, carbonyl, acetic, and phenolic acids [26][27][28]. One of the groups of compounds that have the most role in inhibiting microbial growth is phenolic compounds.…”

Recent Perspectives in Pyrolysis Research

The pyrolysis method has been used in various fields and has attracted the attention of many researchers so that this method can be applied to treat biomass waste. Pyrolysis of biomass occurs through heating a substance with limited oxygen so that the decomposition of complex compounds such as lignocellulose into simpler compounds occurs. The heat energy of the pyrolysis process encourages the oxidation of biomass so that complex carbon molecules break down into carbon and bio-oil. Pyrolysis of biomass for coconut shells, cashew nut shells, and cocoa pod husk was carried out at a temperature of 400–600°C with a flow rate of 6–7°C/min. The content of bio-oil compounds from its biomass based on the analysis of gas chromatography–mass spectroscopy obtained phenolic acid, pyrimidine derivatives, amines, carbamate acids, furans, esters derivatives, pyridine, ketones, furans, and aldehydes that can be used as active compounds for biopesticides.

“…Pada proses pirolisis energi panas mendorong terjadinya oksidasi sehingga molekul karbon yang kompleks terurai sebagian besar menjadi karbon atau arang dan sisanya berupa asap cair (Liquid Volatil Matter (LVM)) (Yaman, 2004). Komponen kimia LVM hasil pirolisis adalah senyawa amonia, heksana, alkohol, keton, karbonil, asam asetat dan fenolik (Mashuni et al, 2017;Ifa et al, 2018;Jahiding et al, 2017).…”

Kulit buah kakao (KBK) adalah limbah organik dari hasil olahan buah kakao yang dapat digunakan sebagai sumber senyawa aktif. Kulit kakao mengandung senyawa selulosa, hemiselulosa dan lignin yang dapat terdekomposisi menghasilkan senyawa fenolik. Penelitian ini bertujuan untuk menentukan kandungan fenolik total atau Total Phenolic Content (TPC) dari liquid volatile matter (LVM) hasil pirolisis KBK dan uji aktivitas antifungi terhadap Fusarium oxysporum. Produksi LVM dihasilkan dari metode pirolisis KBK pada suhu 500 °C. Penentuan TPC dengan metode spektrofotometri UV-Vis menggunakan pereaksi Folin- Ciocalteu (FC) pada panjang gelombang maksimum 765 nm dengan larutan standar asam galat dan diukur setelah dibiarkan selama 60 menit pada suhu kamar. Uji aktivitas antifungi terhadap F. oxysporum dilakukan dengan metode dilusi. LVM dari hasil pirolisis KBK adalah 25,80% (b/b) dengan TPC 100% sebesar 2,28 g/L. Pirolisis KBK menghasilkan LVM yang memperlihatkan aktivitas antifungi dengan konsentrasi hambat minimal (KHM) 1% (v/v) dan konsentrasi bunuh minimal (KBM) 9% (v/v). Oleh karena itu, LVM KBK memiliki potensi untuk diaplikasikan sebagai fungisida alami.Determination of The Total Phenolic Content of Liquid Volatile Matter from Cocoa Pod Husk Pyrolysis and Antifungal Activity Test Against Fusarium oxysporum. The cocoa pod husk (CPH) is an organic waste from the processed cocoa potentially used as source of active compounds. The CPH contains cellulose, hemicelluloses, and lignin compounds that can be decomposed into phenolic compounds. The present study investigated the determination of total phenolic content (TPC) of liquid volatile matter (LVM) of CPH followed by the antifungal activity test against Fusarium oxysporum. The LVM production was performed by the pyrolysis method at temperature of 500 °C. The determination of TPC was evaluated by the UV-Vis spectrophotometric method using the Folin-Ciocalteu (FC) reagent at maximum wavelength of 765 nm with the standart solution of gallic acid measured after 60 min reaction at room temperature. The antifungal activity test against F. oxysporum was carried out by dilution method. The pyrolysis of CPH produces LVM of 25.80% (b/b) contained TPC 100% of 2.28 g/L. The LVM produced in this study shows antifungal activity with a minimal inhibitory concentration (MIC) 1% (v/v) and minimum fungicidal concentration (MFC) 9% (v/v). Therefore, the LVM CPH produced can be applied as a natural fungicide.
