“…The performance of a pyrolysis reaction is determined by several variables, including the pyrolysis temperature, heating rate, nitrogen flow rate, feedstock particle size, and reaction time. In this study, the pyrolysis temperature, nitrogen flow rate, and reaction time were chosen to carry out the process [8][9][10][11][12].…”

Most nations have concentrated on reducing greenhouse gas emissions since global warming is such a serious problem. Due to land use changes, the harvesting of peat for use as fuel in homes, and the gardening industry, peat moss from peat bogs or peat fields may cause smoldering fires and release quantities of carbon dioxide. Bio‐fuel is one of the alternative renewable sources created from organic materials. Pyrolysis, a thermochemical process that converts organic materials into substitutes for fossil fuels and used to create biofuel because it is readily available, straightforward, and inexpensive to implement. The feedstock utilized in this experiment was peat moss. Proximate and ultimate analyses were performed using thermogravimetric analysis and elemental analyzer to determine thermal breakdown and elemental characteristics. Pyrolysis was carried out in this work using a prototype lab scale fixed‐bed pyrolysis. Based on prior study, the parameters used are pyrolysis temperature, nitrogen flow rate and reaction time to create the central composite design model. According to the analysis of variance results, pyrolysis temperature and flow rate were significant, however reaction time was not. The effect of flow rate and reaction time on response was explored. The actual bio‐oil yield achieved utilizing the optimal parameters was 10.02 %. The presence of chemical compounds in bio‐oil was measured.

“…The 7 compounds in the liquid smoke content of grade 3 red fruit seed waste act as a supplementary antifeedant, reducing Cylas Formicarius appetite Antifeedant bioactive compounds could be another crop protection strategy (Isa et al 2019). This substance does not kill, repel (Kendra et al 2014;Faisal et al 2016;Oramahi et al 2018), or entangle insect pests; it just prevents them from feeding (anti-food). An antifeedant compound is a substance that, depending on its potency, can temporarily or permanently suppress eating (Baskar and Ignacimuthu 2012;Alpian et al 2014).…”

Pandanus conoidus, or red fruit, is a nutrient-dense native Papuan plant, whereas Ipomea batatas are the main food for the Wamena people. Biomass from red fruit seed waste can be used as liquid smoke to control Ipomea batatas . At a temperature of between 300 - 450 °C, liquid smoke is produced through a pyrolysis process. Pyrolysis produces phenolic chemicals and aldehydes that have antioxidant and antimicrobial properties (anti-bacterial and anti-fungal). The assessment of pH, acidity, and phenol concentration characterizes the quality of liquid smoke. The potential of red fruit seed waste as a liquid smoke product for biopesticides in Ipomea batatas is explored in this study. Additionally, study development aims to determine the optimal method for pyrolyzing red fruit seed waste, its characteristics, chemical content, and the way to use liquid smoke as a biopesticide in Ipomea batatas . The results showed that the liquid smoke of grade 3 red fruit seed waste contains 7 components that can be detected using a mass spectrometer. The higher the concentration of liquid smoke produced by grade 3 red fruit seeds, the higher the possibility of Cylas formicarius mortality. Cylas formicarius had the highest mortality rate (90%) when tested at a 7% test solution concentration.

AbstrakAspergillus merupakan genus jamur patogen yang menyerang pasca panen hasil tanaman hortikultura, seperti jagung dan kacang-kacangan. Pemanfaatan asap cair untuk mengendalikan pertumbuhan jamur patogen saat pasca panen merupakan salah satu alternatif yang alami dan aman untuk diterapkan. Tujuan penelitian ini adalah untuk menentukan kemampuan daya hambat dan kategori aktivitas antifungi asap cair berbahan dasar kayu mundu (Garcinia dulcis) terhadap jamur Aspergillus niger dan Aspergillus fumigatus serta kandungan senyawa kimianya. Kayu mundu yang digunakan berasal dari Kabupaten Kubu Raya. Media Potato Dextrose Agar (PDA) digunakan untuk uji aktivitas antifungi asap cair. Enam konsentrasi asap cair yaitu 0; 0,5; 1,0; 1,5, 2,0 dan 2,5% digunakan untuk uji dengan dithane M45 sebagai pembanding. Hasil penelitian menunjukkan bahwa asap cair berbahan dasar kayu mundu mampu menekan pertumbuhan jamur A. niger dan A. fumigatus secara signifikan (P <0,05). Konsentrasi asap cair berbahan dasar kayu mundu sebesar 2,5% memberikan hasil terbaik dengan nilai rata-rata penghambatan terhadap jamur A. niger dan A. fumigatus masing-masing sebesar 100 dan 91,81% dan tergolong kategori aktivitas sangat kuat. Uji kandungan senyawa kimia asap cair berbahan dasar kayu mundu mengandung 5 senyawa utama, yaitu 2-propanone, 1,2 ethanediol, acetid acid, phenol 2-methoxy-4-(2-propenyl)-(CAS) eugenol, dan 3-furaldehyde. Asap cair berbahan dasar kayu mundu berpotensi untuk dikembangkan sebagai pengendali serangan jamur patogen A. niger dan A. fumigatus pada pasca panen tanaman hortikultura.AbstractAspergillus is pathogenic fungi that infect post-harvest yields of horticultural crops, i.e., Zea mays and legum. Using liquid smoke is one of the natural and safe alternatives to control fungus and the growth of pathogenic fungi that attack post-harvest yields of cultivated plants. This study aimed to evaluate the antifungal properties of liquid smoke from mundu (Garcinia dulcis) wood against the fungus Aspergillus niger and Aspergillus fumigatus. Mundu wood is from Kubu Raya Regency. The Agar media used was Potato Dextrin Agar (PDA), and concentrations of liquid smoke were 0; 0.5; 1.0; 1.5; 2.0; and 2.5%. The results indicated that the liquid smoke from Mundu wood significantly inhibited the A. niger and A. fumigatus growth (P <0.05). The highest result of liquid smoke from Mundu wood against A. niger and A. fumigatus is a concentration of 2.5% with an average inhibition value of 100 and 91.81%, respectively, with a firm activity level. The contents of liquid smoke contained five dominant compounds, i.e., 2-propanone, 1,2 ethanediol, acetic acid, phenol 2-methoxy-4-(2-propenyl)-(CAS) eugenol, and 3-furaldehyde. Liquid smoke produced from mundu wood has the potential to be developed for the control of pathogenic fungi A. niger and A. fumigatus in post-harvest horticultural crops.
