Abstract

This study aimed to evaluate the effect of blending avocado oil and coconut oil on the resulting physicochemical characteristics. Oil blends were prepared in six ratios of avocado oil to coconut oil (100:0; 80:20; 60:40; 40:60; 20:80; 0:100 v/v). The analyzed parameters included peroxide value, free fatty acids (FFA), iodine value, saponification value, fatty acid profile (GC-FID), and color test. The results showed that the blend in treatment C, with a ratio of avocado oil to coconut oil (60:40 v/v), yielded a peroxide value of 9.23 ± 0.32 meqO₂/kg, FFA of 0.73 ± 0.17%, iodine value of 47.33 ± 0.71 g I₂/100 g, and saponification value of 202.33 ± 0.54 mg KOH/g. The fatty acid profile was dominated by oleic acid, lauric acid, and palmitic acid. This blend produced a more diverse fatty acid profile and exhibited better oxidative stability compared to pure avocado oil. Therefore, blending avocado oil and coconut oil at a ratio of 60:40 v/v resulted in an oil product with a more varied fatty acid composition and improved oxidative stability compared to pure avocado oil.

Abstract

Plastic waste poses a significant environmental challenge due to its non-biodegradable nature, emphasizing the need for sustainable alternatives like bioplastics from natural resources. This study develops and characterizes bioplastic films made from carboxymethyl cellulose (CMC) derived from bacterial cellulose synthesized using pineapple biowaste. Pineapple waste underwent fermentation to produce bacterial cellulose, which was chemically modified into CMC. Films were fabricated using CMC solutions with varying glycerol concentrations (0.5%, 1.0%, 1.5%, and 2.5% v/v). Characterization techniques, including SEM, XRD, FTIR, TGA, mechanical testing, and antibacterial assays, revealed that increasing glycerol concentrations smoothed the film's cross-sectional morphology, reduced crystallinity, and altered functional groups (e.g., new peaks at 870 cm⁻¹ and 935 cm⁻¹ attributed to C–H deformation). TGA indicated a four-stage thermal degradation pattern, with mass loss increasing from 77.2% to 88.4% at 2.5% glycerol, reflecting enhanced plasticization. Mechanical testing showed that the highest glycerol concentration increased film flexibility by 40.7 times while reducing tensile strength by 89.7%. Antibacterial activity against E. coli and S. aureus also improved with glycerol content. These results demonstrate the potential of CMC-based bioplastic films as sustainable packaging materials, offering customizable properties and promoting the value-added use of agricultural waste.

Abstract

Kesegaran merupakan parameter kualitas utama yang menentukan penerimaan konsumen serta derajat kehilangan pasca-panen pada buah mangga (Mangifera indica L.). Penentuan kesegaran mangga (Mangifera indica L.) yang ada saat ini sebagian besar didasarkan pada sifat fisik dan kimia umum, yang seringkali tidak dapat mendeteksi dengan baik pembusukan biokimia selama periode penyimpanan. Tujuan artikel ini adalah untuk mengeksplorasi kesegaran mangga berdasarkan perubahan dinamis kadar asam sitrat dan kandungan gula terlarut menggunakan high-performance liquid chromatography (HPLC). Buah yang sudah matang disimpan pada dua suhu berbeda, yaitu 25°C dan 10°C, di mana pengamatan kadar asam sitrat, sukrosa, glukosa, dan fruktosa dilakukan setiap hari dari hari ke-1 hingga hari ke-5. Data yang didapatkan dengan jelas memperlihatkan perbedaan pola pada kadar asam sitrat dan gula terlarut buah mangga yang disimpan disuhu 25°C dan 10°C. Pada suhu 25 °C, kadar asam sitrat turun tajam, sedangkan pada suhu 10 °C kadarnya relatif stabil. Peningkatan sukrosa dan penurunan glukosa lebih nyata pada suhu 25 °C dan 10 °C. Kadar fruktosa hanya sedikit lebih tinggi pada suhu 25 °C dibandingkan pada suhu 10 °C. Analisis statistik mengkonfirmasi bahwa suhu penyimpanan berpengaruh pada kadar asam sitrat dan komposisi gula. Perilaku terkoordinasi asam sitrat dan berbagai gula inilah yang menjadi ciri khas 'sidik jari kimia' mangga, yang berarti kita dapat menggunakan kadar zat-zat ini sebagai ukuran kesegaran buah. Semakin tinggi suhu, semakin cepat perubahan metabolisme dan semakin kurang segar buahnya. Penyimpanan suhu rendah menjaga laju metabolisme tetap stabil dan menunda penurunan kualitas, namun tetap saja, kita dapat menggunakan kadar asam sitrat dan gula sebagai cara yang andal untuk mengukur kesegaran mangga.

Abstract

The development of eco-friendly cosmetics using local bioresources like Uncaria gambir Roxb. (gambir) holds strong promise for sustainable innovation. This study formulates and evaluates a catechin-based solid shampoo enriched with purified gambir extract, aiming to enhance product stability. A 14-day storage test was conducted at 20 °C and 40 °C using three types of packaging: translucent plastic, aluminum foil, and amber glass. Visual observations revealed that higher temperatures, especially in translucent plastic, accelerated color degradation due to catechin instability. Amber glass was the most effective in preserving the shampoo’s original color. Further, aqueous stability was assessed through two wet-use simulations: soaking (full immersion in distilled water) and dipping (partial immersion daily over four days). The shampoo maintained physical integrity during both tests, showing no softening or structural deformation. However, water discoloration increased over time, indicating catechin release and oxidation. The extent of browning was influenced by the pH of the water, suggesting that both environmental pH and oxidative exposure affect catechin behavior during use. These results demonstrate the solid shampoo’s physical resilience and moderate color stability under thermal and aqueous stress. While catechin oxidation is unavoidable, its rate can be mitigated through optimal packaging and pH management. The gambir-based solid shampoo shows potential as a natural, environmentally friendly personal care product, although further formulation refinement is needed to improve color retention during storage and use.

Abstract

The Central Laboratory of Universitas Andalas is equipped with Shimadzu 9050 Quadrupole Time-of-Flight (QTOF) LC-MS/MS instrument, which has strong potential to support scientific research at international standards. However, the utilization of this instrument remains limited due to the lack of optimized standard methods for both qualitative and quantitative analyses. This study aims to develop an LC-MS/MS analytical method that can be used as a standard method for research services in the laboratory. The research stages included sample preparation of red flower (BM) and white flower (BP) by extraction of sample using methanol pH 3 as the solvent, separation of sample using a rotary evaporator, method optimization including selection of mobile phase composition (isocratic and binary gradient), selection of analysis time (5, 10, and 15 minutes), and optimization of collision energy in the range of 5–40. Quantitative analysis of flower samples was then conducted using the optimized method. The optimisation results showed that a binary gradient mobile-phase method with an analysis time of 15 minutes and a collision energy of 25 could be used as the analytical method. Furthermore, quantitative analysis of both flower samples revealed that cyanidin in the red flower sample was 24.92 ppm, while cyanidin in the white flower sample was 71.69 ppm.

Abstract

Various types of onions have long been utilized as both culinary ingredients and traditional medications, yet comprehensive comparative data on their chemical composition and antioxidant potential in Indonesia are limited. This study provides the first integrated analysis of six onion species cultivated in West Sumatra, namely, shallot (A. cepa var. ascalonicum), garlic (A. sativum), common onion (A. cepa L.), Dayak onion (Eleutherine palmifolia), chive (A. tuberosum), and leek (A. fistulosum L.). Physicochemical properties were determined through proximate analysis, antioxidant activity was assessed using the DPPH assay and expressed as IC₅₀ values, and lipid-based phytochemical profiles were obtained via Bligh and Dryer extraction, followed by GC–MS. Data were processed and visualized in RStudio. The results indicate that chive exhibited the highest moisture (93.57%) and fat (4.15%) contents, whereas Dayak onion contained the highest amounts of ash (6.29%) and protein (8.74%). Dayak onion exhibited strong antioxidant activity (84.85 ppm), whereas common onion, shallot, and leek demonstrated weak antioxidant activity. Cis-vaccenic acid was the dominant compound in shallot (37.59%) and leek (31.19%), and D-limonene was the dominant compound in Dayak onion (22.39%) and chive (21.16%). The study findings highlight that the Dayak onion is a promising indigenous source of natural antioxidant for functional food and herbal product development, while providing novel baseline phytochemical data for advancing onion bioactivity and biodiversity research.

Abstract

Gambier (Uncaria gambir Roxb.) contains potent bioactive compounds with strong natural antimicrobial properties, making it a promising ingredient for acne treatment. However, its application in topical formulations remains limited due to a lack of understanding regarding the impact of processing conditions, particularly heating, on its functional efficacy. This study investigated the effect of heating duration on the characteristics of an acne treatment balm formulated with black cube gambier. Experiments using a completely randomized design (CRD) were carried out for 0, 30, 60, 90, and 120 minutes of heating durations to evaluate the balm's physical, chemical, and microbial properties. The results demonstrate that heating duration significantly influenced key parameters, including homogeneity, spreadability, melting point, irritation potential, texture, color, pH, total phenol content, and antibacterial activity (p < 0.05). The most optimal results were obtained at 120 minutes, yielding a balm with superior homogeneity, spreadability (4.47 cm), melting point (50°C), pH (7.44), total phenol content (54.28%), and diameter of the inhibition zone (16.35 mm). FTIR analysis confirmed an increase in phenolic compound stability, indicating enhanced antibacterial potential. These findings suggest that extended heating duration improves the stability and performance of gambier-based formulations. The optimized acne balm formulation highlights the potential of locally sourced gambier as a natural, eco-friendly acne treatment. Further research is recommended to evaluate product shelf-life, consumer acceptability, and industrial scalability.

Abstract

Purpose: This work aimed to analyze the profiles of amino acids in the ficin enzyme isolated from Ficus aurata (Miq.), and to determine the efficiency of these amino acid concentrations under two types of drying – solar drying and freeze drying. Methodology: The enzyme ficin was obtained from fig tree, and the presence of amino acids was determined by UPL chromatography. The applied methods of drying were solar and freeze. However, the primary objectives were aimed at investigating the influence of these treatments on the level of amino acids present in all the samples. Results: The findings indicated that freeze drying techniques retained more amino acids in figs than was observed in the case of solar drying. In particular, the amount of L-glutamic acid in freeze drying was 2.39 mg/g, while that of solar drying was 1.43 mg/g. Similar results were observed in L-lysine and L-aspartic acid, which were relatively higher in freeze drying than solar drying, with concentrations of 2.43 mg/g and 2.55 mg/g, respectively, as opposed to 0.99 mg/g and 1.76 mg/g in solar drying. Besides, freeze drying showed better L-serine, L-phenylalanine, and L-histidine preservation. Findings: It was observed that freeze drying gave the best opportunity to reduce the loss of amino acid of the ficin enzyme. The drying method, in particular, resulted in a concentration of some important amino acids like L-glutamic acid, L-lysine, L-aspartic acid, L-serine and L-phenylalanine, and L-histidine as compared to solar drying. Novelty: This study focused on different types of solar energy and freeze energy economic systems in enzymatic activities in the ficin enzyme extracted from Ficus aurata (Miq.). The novel contribution of this research lies in its objective, which is to show how the drying methods used affected the retention of the most influential and critical amino acids in the enzymatic processes. Originality: The novel aspect of the study was the attachment of ultra vortices to different drying techniques, such as solar drying and freeze drying in select ficin enzymes from Ficus aurata. It opens up a new perspective toward the development of drying parameters for the enhancement of important enzymatic characters from this particular variety. Conclusion: This research considers the changes in amino acid content during the drying of ficin enzyme from Ficus aurata through different drying methods. It is shown that freeze drying enhances the retention of critical amino acids and is thus one of the most efficient methods for the enzymatic processing of this plant species. Type of Paper: Empirical research paper.
