The process of hydrolysis of maltodextrin with an α-amylase enzyme using different concentrations will affect the characteristics product. Maltodextrin from Cavendish banana flour is considered a new product on an industrial scale, so it needs to be analyzed by industry attitudes. The purpose of research was to determine the best concentration of α-amylase enzyme, analyze industry attitudes, and determine the level of importance of attributes. This research was arranged in a Completely Randomized Block Design (CRBD) with a single factor (concentration of α-amylase enzyme) and 4 repetitions. Cavendish banana flour is hydrolyzed using the α-amylase enzyme with concentrations of 0.2, 0.4, 0.6, 0.8, 1.0, 1.2%. Then, the best treatment is analyzed based on industrial attitudes by considering sensory attributes. The results of the research showed the best concentration of α-amylase enzyme was 1.2% treatment with yield (89.88%), water content (4.20%), ash content (1.06%), solubility (47.23%), viscosity (2.79mPas), pH (5.92), and DE value (18). The results of the industrial attitude analysis showed a positive attitude with the color attribute (1.79%) being the main attribute that influenced the level of importance of the industrial attitude analysis.</p> <p><em>Keywords: </em>cavendish banana, maltodextrin, α-amylase enzyme, industrial attitude analysis, and product importance level.</p> <p>In Bahasa:</p> <p>Pisang Cavendish (<em>Musa acuminata colla</em>) merupakan pisang yang mudah rusak, namun memiliki kandungan pati tinggi (70-80%) pada kondisi mentah, sehingga dapat dimanfaatkan menjadi maltodekstrin.

This research aimed to determine the optimal concentration of ethanol extract of avocado seeds in relation to its inhibitory concentration (IC<sub>50</sub>), the improvement of the sun protection factor (SPF), and the sunscreen characteristics that meet the quality standards of SNI 16–4339–1996 for sunscreen products. A completely randomized design (CRD) was used with four concentrations of extract (0.25%, 0.5%, 0.75%, and 1%) and four replications. The observed parameters included pH, viscosity, SPF, spreadability, homogeneity, antioxidant activity (IC<sub>50</sub>), and sensory attributes (aroma, color, and texture). Data were analyzed using Analysis of Variance (ANOVA) and followed by Duncan’s Multiple Range Test (DMRT) at the 5% level. Increasing the concentration of ethanol extract of avocado seeds significantly increased antioxidant activity, SPF, and spreadability, while decreasing pH and viscosity. The best treatment was 0.75% concentration of avocado seed ethanol extract, with a pH of 6.77, viscosity of 2869.48 cP, SPF of 15.21 (maximum category), spreadability of 6.53 cm, and IC<sub>50</sub> of 45.71 ppm (very strong antioxidant).

Cherry coffee fruit beans were fermented with orange and tamarillo pulp, then dried, ground with a moisture content of 12%, and extracted using a Soxhlet with hexane and ethanol as solvents, and then were analyzed using Gas Chromatography–Mass Spectrometry (GC–MS). GC–MS analysis showed that both the fruit substrate and the extraction solvent influenced the resulting chemical profiles. Hexane extraction of orange-fermented coffee revealed non-polar compounds such as hexadecenoic acid methyl ester, 9-octadecenoic acid methyl ester (E), and several phthalates. Ethanol extraction produced a richer profile, dominated by fatty acid ethyl esters (FAEEs), including ethyl palmitate, linoleic acid ethyl ester, ethyl oleate, and ethyl stearate, alongside caffeine. Tamarillo-fermented samples displayed similar patterns of FAEEs in ethanol extracts and additionally contained 9,12-octadecadienoyl chloride (Z,Z). A notable finding was the presence of Patchouli alcohol exclusively in the hexane extract of tamarillo -fermented coffee, suggesting that fermentation facilitated the formation of unique terpenoid derivatives.</em></p> <div><em><span lang="SQ">Keywords: coffee powder, fermentation, GC-MS, tropical fruits, chemical compounds </span></em></div>2026-09-29T00:00:00+00:00Copyright (c) 2026 https://www.jurnal.fp.unila.ac.id.103-3-46-85.cpanel.site/index.php/JTHP/article/view/12089Comparison of milling and sensory qualities of several rice in Banjarbaru 2026-05-05T06:22:05+00:00Tanwirul Millatit_millati@ulm.ac.idRini Hustianyt_millati@ulm.ac.idSusit_millati@ulm.ac.idAgung Nugrohot_millati@ulm.ac.id<p><em>Rice remains the primary staple food for approximately 90% of Indonesia’s population and provides more than half of their daily caloric intake.

The first stage involved producing fermented cabbage waste liquid using a Completely Randomized Design (CRD) with two factors: salt (NaCl) concentration at 3%, 5% and 7%, and fermentation duration of 4, 6, 8, and 10 days. The second stage involved applying the fermented cabbage waste liquid to large red chili by soaking the fruits for 12 hours, followed by storage at room temperature (27–29°C).

The purpose of this study was to analyze the reduction of caffeine levels, fermentation pH, bean pH, and bean density through a wet fermentation process assisted by an Extremely Low Frequency (ELF) magnetic field. The research was conducted using a 3×2 factorial design. The process was carried out using variations in magnetic field intensity (control, 300 µT, and 500 µT) and contact times (30 and 60 minutes). Fermentation was carried out for 20 hours utilizing tape yeast as a starter, followed by the measurement of fermentation pH every 5 hours, and the subsequent characterization of bean pH, density, and caffeine levels. The application of an ELF magnetic field during fermentation holds the potential to increase microbial activity, thereby reducing the caffeine levels of the coffee beans. The results showed that the fermentation and bean pH values decreased, accompanied by an increase in density; however, these values were not significantly different among the groups (p-value > 0.05). The best treatment was obtained from an intensity of 300 µT with a contact time of 30 minutes, resulting in a caffeine content of 0.0234%. This was lower than the negative control (0.0329%), representing a 28.9 percent reduction.
