Abstract

Green algae (Chlorophyceae) are a lignocellulosic biomass with considerable potential as a source of ?-cellulose due to their relatively high cellulose content. This study aimed to produce ?-cellulose via alkaline delignification and to investigate the effects of NaOH concentration and delignification time on the resulting product's characteristics. The delignification process was carried out using NaOH concentrations ranging from 6% to 14% and delignification times of 30–90 min at 60°C. The resulting product were analyzed using the Chesson-Datta method and further characterized by FTIR and SEM analyses, while process optimization was performed using Response Surface Methodology (RSM). The results showed that the optimum conditions were achieved at an NaOH concentration of 8% and a delignification time of 45 min, yielding an ?-cellulose content of 51.2%, a hemicellulose content of 16.9%, and a lignin content of 5.4%. FTIR analysis confirmed the presence of functional groups characteristic of ?-cellulose, whereas SEM observations revealed morphological changes in the fiber surface, which became rougher and more porous due to the removal of lignin and hemicellulose. RSM optimization predicted optimum conditions yielding 51.234% ?-cellulose, 12.990% hemicellulose, and 4.963% lignin.

Abstract

Tea-based beverages continue to evolve in response to growing consumer demand for healthier, more diverse drink options. Among these products, conventional brewed tea and kombucha represent two categories with distinct processing methods and sensory characteristics. Brewed tea is generally appreciated for its familiar taste and mild flavor, whereas kombucha offers a more complex sensory profile due to fermentation processes involving organic acid production and carbonation. Understanding consumer perception toward these beverages is important for product development and market positioning. This study aimed to characterize the sensory attributes of commercial tea and kombucha beverages and to evaluate consumer preference using rapid sensory profiling methods. Six commercial beverage samples, consisting of brewed tea and kombucha products, were analyzed using Flash Profile and Check-All-That-Apply (CATA) methods. Flash Profile evaluation was conducted by semi-trained panelists, while CATA assessment involved consumer respondents to capture product perception and preference patterns. The results showed clear sensory differentiation between brewed tea and kombucha beverages. Brewed tea products were generally associated with sweetness, tea aroma, brown appearance, and lighter mouthfeel, while kombucha samples were characterized by sourness, fermented aroma, sparkling sensation, and lingering acidity. Consumer preference analysis indicated that Kombucha D was closest to the ideal product due to its balanced sensory profile, particularly clarity, smoothness, and sweetness, and its lower dominance of sharp, fermented, and acidic attributes. The combination of Flash Profile and CATA provided complementary information for rapid beverage evaluation and may serve as a practical approach for sensory-based product development in the beverage industry.

Abstract

This study aimed to analyze the adoption level of Healthy Rice Seed and Crop Management (HRSCM) and examine determinants influencing its adoption among rice farmers in Bogor Regency, Indonesia. The study was conducted in Jonggol and Tanjungsari Districts, involving 105 rice farmers who participated in the Integrated Crop Management Farmer Field School (ICM-FFS) program. Data were collected through structured questionnaires and analyzed using descriptive statistics and Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results showed that the overall HRSCM adoption level was generally high. SEM-PLS analysis revealed that environmental support had the strongest positive effect on HRSCM adoption (? = 0.669; p<0.001), followed by farmer characteristics (? = 0.232; p<0.001) and FFS extension effectiveness (? = 0.156; p<0.05). Extension support showed a significant negative effect (? = ?0.304; p<0.001), whereas farmers’ perceptions of innovation characteristics had no significant effect on adoption behavior. These findings suggest that once farmers are familiar with HRSCM practices, adoption decisions are shaped primarily by environmental and institutional conditions rather than by differences in farmers’ perceptions of innovation characteristics. Improving access to production resources, strengthening institutional and environmental support, and developing adaptive extension systems are therefore essential for increasing HRSCM adoption.

Abstract

This study aimed to compare the effectiveness of ohmic heating and conventional heating on vitamin C retention, antioxidant activity, and total plate count (TPC) of snake fruit (Salacca zalacca) juice. The best ohmic heating treatment was determined using the De Garmo effectiveness index method and subsequently compared with conventional heating using an Independent Sample t-test. The best treatment was obtained at 80°C for 1 min (A3B1) with an effectiveness index value of 0.61. The results showed that the best ohmic heating treatment produced vitamin C content of 2.52 mg/100 mL, antioxidant activity of 65.88% inhibition, and TPC of 1.40 log CFU/mL. In comparison, conventional heating produced vitamin C content of 1.37 mg/100 mL, antioxidant activity of 62.22% inhibition, and TPC of 3.00 log CFU/mL. Statistical analysis indicated significant differences (p<0.05) in vitamin C, antioxidant activity, and TPC between ohmic heating and conventional heating. The results demonstrated that ohmic heating was more effective in retaining vitamin C and antioxidant activity while reducing microbial load than conventional heating. Therefore, ohmic heating has potential as an alternative pasteurization technology for producing high-quality and microbiologically safe snake fruit juice (Salacca zalacca).

Abstract

The design flood discharge is an important parameter in hydrological analysis used as a basis for flood control structure planning and water resources management. This study aims to determine the design flood discharge in the Alo Watershed through analysis of areal rainfall, design rainfall, effective rainfall, and the Nakayasu Synthetic Unit Hydrograph (HSS). Areal rainfall was calculated using the Thiessen Polygon method based on rainfall data from seven rainfall stations, namely Gedangrowo, Kludan, Putat, Kedungcangkring, Porong, Krembung, and Budugbulus during the observation period of 2016–2025. The design rainfall was analyzed using the Log Pearson Type III Distribution and tested using the Chi-Square and Smirnov-Kolmogorov methods at a significance level of 5%. Furthermore, the design rainfall was converted into a 6-hour hourly rainfall distribution using the Mononobe Method, then calculated as effective rainfall with a runoff coefficient of 0.204. The effective rainfall distribution is used as input in the formation of flood hydrographs using the Nakayasu Synthetic Unit Hydrograph (HSS) Method. The results of the study indicate that the Log Pearson Type III Distribution meets the distribution suitability test so it is suitable for use in the analysis of planned rainfall in the Alo Watershed. The Nakayasu HSS analysis shows that the peak flood discharge occurs at the 2nd hour for all return periods and increases as the return period increases. The Design Flood Discharge obtained for return periods of 2, 5, 10, 25, and 50 years is 63.933 m³/s, 72.446 m³/s, 77.339 m³/s, 82.922 m³/s, and 86.742 m³/s, respectively. The results of this study can be used as a basis for planning flood control structures and water resource management in the Alo Watershed.

Abstract

Generator sets are widely used as a backup power source for household and small industrial applications. The reliability of a generator set is strongly influenced by the condition of its engine components and the maintenance quality. This study aims to evaluate the performance of a Firman FPG1500ECII generator set after maintenance and overhaul using three different gasoline fuels, namely Pertalite, Pertamax 92, and Pertamax Turbo. The research stages consisted of visual inspection, failure identification, maintenance and overhaul processes, and performance testing under a constant load of 540 W. The performance parameters investigated included electrical power output, fuel mass flow rate, Specific Fuel Consumption (SFC), electrical efficiency, and Brake Thermal Efficiency (BTE). Initial inspection results revealed failures in the piston ring, connecting rod bearing, and main bearing, as well as carbon deposits in the combustion chamber and valve system, causing the generator set to fail completely. After maintenance and overhaul, the generator set was successfully restored and subjected to performance testing. The results indicated that fuel type significantly affected generator performance. Pertamax Turbo exhibited the best performance with a fuel mass flow rate of 0.2751 kg/h, SFC of 1.557 kg/kWh, electrical efficiency of 5.18%, and BTE of 76.55%. In contrast, Pertalite showed the highest fuel consumption with a fuel mass flow rate of 0.4155 kg/h, SFC of 2.405 kg/kWh, electrical efficiency of 3.36%, and BTE of 50.68%. The findings demonstrate that maintenance and overhaul successfully restored the operational performance of the generator set, while higher-octane fuels improved combustion efficiency and overall generator performance after maintenance.

Abstract

The increasing demand for natural flavor enhancers has encouraged the development of alternatives to synthetic monosodium glutamate (MSG). This study evaluated the physicochemical properties and sensory acceptance of a bromelain-hydrolyzed seasoning powder formulated from oyster (Crassostrea sp.), oyster mushroom (Pleurotus ostreatus), and tomato (Solanum lycopersicum) with the addition of spices. A completely randomized factorial design was applied using two factors: the proportion of oyster, oyster mushroom, and tomato, and spice concentration. The evaluated parameters included protein content, moisture content, ash content, water solubility index (WSI), yield, sensory acceptance, zinc content, and glutamic acid content. The results showed that raw material proportion significantly affected all physicochemical characteristics, while spice concentration significantly influenced protein content and WSI. Significant interactions between both factors were observed for moisture content, ash content, and yield. Sensory evaluation indicated significant differences in taste and overall acceptance among treatments. The optimum formulation consisted of oyster, oyster mushroom, and tomato in a 40:40:20 proportion, with a 3% spice concentration, producing a seasoning powder containing 15.30% protein, 3.98% moisture, 6.75% ash, 20.75% yield, 166.7 mg/kg zinc, and 18,307.70 ppm glutamic acid. These findings demonstrate the potential of bromelain hydrolysis to produce a natural seasoning powder rich in zinc and glutamic acid, with desirable physicochemical and sensory characteristics; the appetite-supporting potential suggested by these compounds remains hypothetical and requires confirmation through future biological or clinical studies.

Abstract

Sonneratia caseolaris, also known as pedada, is a mangrove fruit that is not widely used, despite its great potential for making healthy drinks due to its many beneficial substances. This study aimed to check the plant chemicals and heavy metals in pedada juice that uses natural colors from roselle and beetroot. Tests were conducted to detect certain chemicals, such as phenolic compounds, flavonoids, and alkaloids, and to measure the levels of tin and mercury in the sample. The findings showed that the extracts from pedada, roselle, and beetroot had phenolic compounds, but no flavonoids or alkaloids were found. The presence of phenolic compounds suggests that the drink may have antioxidant properties. In addition, the levels of tin and mercury were measured as 0.026 mg/kg and 0.009 mg/ kg, respectively. These values were well below the maximum allowed by food safety rules, indicating the product is safe for people to eat. The results show that extracts from roselle and beetroot can be good natural colorants for pedada-based drinks and also help improve their healthful qualities without making the product unsafe. Therefore, pedada fruit is a good raw material for making special drinks that add value to mangrove resources.

Abstract

This study examined the effects of seaweed species and solvent types on the yield and phytochemical profile of seaweed extracts obtained via Ultrasound–Microwave Assisted Extraction (UMAE). Five types of seaweed Eucheuma cottonii, Gelidium sp., Gracilaria sp., Sargassum sp., and Ulva lactuca were extracted using methanol and ethanol. Phytochemical screening was conducted for alkaloids, phenols, flavonoids, saponins, tannins, steroids, and terpenoids. The results showed that the extract yield ranged from 18.16% to 48.37%, with the highest yield of 48.37% observed in the methanol extract of E. cottonii. Total soluble solids ranged from 14.0% to 37.5%, with the highest value of 37.5% found in the methanol extract of E. cottonii. Phenolic compounds were detected in most extracts; flavonoids were present in all methanol extracts and some ethanol extracts; saponins were found in E. cottonii, Gracilaria sp., Sargassum sp., and Ulva lactuca; steroids were present in the ethanol extracts of Gracilaria sp. and Sargassum sp.; and terpenoids were detected in E. cottonii, Gelidium sp., and U. lactuca. The results indicate that the type of solvent affects the yield, total dissolved solids, and phytochemical profile of the extracts; thus, the Ultrasound–Microwave Assisted Extraction (UMAE) method has the potential to be an effective green extraction method for various types of seaweed.

Abstract

Oil palm plantations require accurate and timely inventory data to support plantation management, productivity assessment, and sustainable agricultural practices. However, manual tree inventory in large plantation areas is labor-intensive, time-consuming, and prone to human error. This study proposes an automated approach for oil palm crown detection and tree counting using high-resolution Unmanned Aerial Vehicle (UAV) imagery. To improve image quality, Contrast Limited Adaptive Histogram Equalization (CLAHE) was applied as a preprocessing step, and the Roboflow Detection Transformer (RF-DETR) was used as the object detection model. The proposed method was evaluated using 1,135 UAV images containing 56,547 annotated oil palm crowns collected from commercial plantations in West Kalimantan, Indonesia. Experimental results demonstrate that the proposed approach achieved mAP@50 of 97.5%, precision of 97.1%, recall of 96.0%, and F1-score of 96.6% for oil palm crown detection. In the tree-counting evaluation, the system successfully detected 1,105 of 1,120 ground-truth trees, achieving an overall accuracy of 98.5%. Furthermore, the proposed method achieved an average detection time of 16.1 ms, indicating high computational efficiency. These results demonstrate that the proposed framework provides an effective and practical solution for automated oil palm inventory and plantation monitoring using high-resolution UAV imagery.
