Abstract

Lignin reduced the adhesion between the polymeric matrix and natural reinforcement in composite materials by its hydrophobic characteristic. Removal of lignin can be a solution to improve fiber function in composite use. This study aimed to determine the degradation of lignin at different times of pulping. The soda process was conducted at 60, 70, 80, 90, and 100 minutes of pulping using heat in a room atmosphere. Yields, lignin content, and lignin spectrum (FT-IR analysis) were measured.  The result showed the highest degradation of lignin was in 100 minutes of pulping with 80.34% lignin degradation and 3.57% lignin left in fibers. However, the yield of fibers decreased with increasing pulping time due to lignin removal. 100 minutes of pulping time showed the highest loss of fiber yield. This study showed the best pulping time for kapok fiber is 100 minutes with 3.57 % lignin remaining in the pulp.

Abstract

Recycling is important for achieving environmentally sustainable products and waste reduction. The trend has led to the addition of reinforcement to recycling process to ensure the effective usage of wasted papers. Therefore, this study was conducted to determine the effect of using cellulose nanofiber (CNF) synthesized from kapok fibers as reinforcement in recycled papers. CNF was applied at different concentrations of 2, 4, 6, 8, and 10% of recycled paper production and the analysis was conducted by testing tensile index, density, and brightness. Moreover, X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and UV-Vis analysis were used to determine the characteristics of the paper. The results showed that CNF addition influenced tensile index, brightness, and density of recycled papers. This was observed from an increase in tensile strength by up to 76.32% and density at approximately 0.58 g/cm3 for 10% CNF addition. Meanwhile, the brightness level was reduced due to the compact nature of paper produced. The trend led to the conclusion that the addition of CNF could impact the characteristics of recycled papers.

Abstract

Essential oils, including those used in aromatherapy, are currently in high demand as consumers increasingly prefer products made from natural ingredients. Citronella oil, when used as aromatherapy, is intended to relieve headaches, enhance breathing, and produce a warming effect upon inhalation. Aromatherapy necklaces provide a convenient and portable method for delivering the benefits of essential oils. Encapsulation technology addresses the volatility of essential oils in aromatherapy gels by creating a controlled slow-release mechanism, enabling the gradual release of essential oils over a specified period. This study aims to evaluate the characteristics of aromatherapy necklaces and assess the aroma intensity of citronella oil through sensory analysis. Sensory analysis was conducted using semi-trained and trained panelists. The aromatherapy necklace comprises a mixture of gels and emulsions containing encapsulated essential oils, formulated for immediate use. The sensory analysis results indicated that the addition of 10% essential oils yielded the highest scores for color and texture assessments (4.08 and 3.96, respectively), while the addition of 7.5% essential oils produced the highest score for aroma assessment (4.16). The aroma intensity decreased from a score of 6.00 on day 1 to 3.17 on day 7. The gradual and controlled decline in aroma intensity aligns with the intended purpose of the essential oil encapsulation process.

Abstract

Dry gambier extract obtained from gambier plants contains tannins at relatively low levels. Tannins can be obtained by extracting dry gambier using water to achieve high yields within a relatively short processing time. This study aims to analyze the interaction between extraction time and microwave power in the tannin extraction process from gambier using the microwave-assisted extraction (MAE) method to maximize tannin yield.  The research method employed was a factorial design (AxB). Factor A was extraction time, consisting of five treatments (1; 2; 3; 4; and 5 minutes) and factor B was microwave power, consisting of five variations (180W; 300W; 450W; 600W and 850W). The results showed that the gambier extraction process using MAE demonstrated an interaction between extraction time and microwave power on the yield produced, but not on the tannin content. The most optimal temperature and power that can be used is 4 minutes at 600W microwave power with a yield of 44.66%. The treatment of temperature and microwave power in the gambier extraction process showed a significant interaction with the extract yield.

Abstract

Coconut-based production generates waste such as coconut husk, which contains up to 35% lignocellulose—a valuable raw material for furfural production. This study aimed to determine the impact of coconut maturity level and coconut husk section on the lignocellulose content in coconut husk. This study used a randomized group design with two factors: coconut maturity level and coconut husk section. The variables observed were moisture, extractive, cellulose, hemicellulose, and lignin contents. Analysis of Variance (ANOVA) was performed for data analysis, followed by Duncan's Multiple Range Test (DMRT). The coconut fruits used were immature and mature ones. This study analyzed the husk at the proximal end, equator, and distal end of the coconut fruit. The results show significant effects of coconut maturity level on the chemical composition of coconut husk at the three sections of the coconut, indicating coconut husk’s potential as a raw material for furfural production.
