Abstract

Pangasius hypophthalmus is one of the economically superior freshwater fish commodities in Riau Province, Indonesia, which is characterized by high protein content but experiences rapid quality decline during storage at room temperature due to proteolytic enzyme activity and microbial spoilage. This study aims to determine the effect of lime (Citrus hystrix) peel concentration and storage time on catfish protein quality and to develop contextual biotechnology learning posters for grade XII high school students based on the research results. This study used a quantitative experimental approach using a factorial Completely Randomized Design (RAL) with two factors: lime peel concentration (0 g, 200 g, 300 g, and 400 g) and storage time (3, 5, and 7 days) at room temperature (25–30°C), resulting in 36 experimental units. The parameters analyzed included protein content using the Kjeldahl method, pH value, Total Plate Count (TPC), organoleptic characteristics (color, aroma, texture and taste) and hedonic. Data were analyzed using Analysis of Variance (ANOVA) followed by the Duncan's Multiple Range (DMRT) test. The poster development adopted the ADDIE model and was validated by media experts, material experts, and biology teachers. The results showed that lime peel concentration significantly affected catfish protein quality. The 300 g treatment showed the highest protein content (20.96–21.88%), the lowest microbial growth, and superior organoleptic characteristics during the storage period. In contrast, the control treatment showed the most significant protein degradation and microbial proliferation. The developed biotechnology learning poster achieved very high validity scores from the media and relevant experts, demonstrating its suitability as an innovative and contextual educational resource.

Abstract

Cassava peel waste is a by-product of cassava processing that still contains fiber and starch, making it a potential alternative food resource. However, its utilization is limited by its high crude fiber content and the presence of hydrogen cyanide (HCN). One approach to improving the quality of cassava peels is fermentation using Lactobacillus fermentum. This study aimed to determine the effect of different fermentation durations on the characteristics of cassava peel flour (Manihot esculenta) fermented with Lactobacillus fermentum. An experimental method was employed using treatments consisting of different fermentation periods (0, 48, and 72 hours) and Lactobacillus fermentum concentrations (0%, 10%, and 20%). The observed parameters included hydrogen cyanide (HCN) content, protein content, crude fiber content, and pH value. Data were analyzed using Analysis of Variance (ANOVA), followed by the Least Significant Difference (LSD) test at a 5% significance level. The results showed that fermentation duration and Lactobacillus fermentum concentration significantly affected the characteristics of cassava peel flour. The 72-hour fermentation treatment produced the best characteristics, with the lowest HCN content (0.15%), crude fiber content of 40.80%, and pH value of 3.56. Overall, fermentation for 72 hours improved the quality of cassava peel flour, indicating its potential as a value-added alternative food ingredient.

Abstract

Macrofungi play an important role in maintaining ecosystem balance as decomposers, food sources, and indicators of environmental quality. The oil palm plantation of PT Inecda Plantation Seberida provides abundant organic matter, creating favorable conditions for the growth of various macrofungal species. This study aimed to identify the species of macrofungi and analyze their diversity in the oil palm plantation area of PT Inecda Plantation Seberida, Indragiri Hulu Regency, Riau Province. The research employed a quantitative descriptive approach using survey methods and purposive sampling techniques. Data were collected through direct field observations, morphological identification of macrofungi, and analyses of the Shannon–Wiener diversity index, evenness index, and dominance index. The results revealed the presence of 22 macrofungal species belonging to the phyla Basidiomycota and Ascomycota, as well as one species from the Myxomycota group. The diversity index (H') ranged from 1.68 to 2.18, indicating a moderate level of diversity, while the evenness index ranged from 0.54 to 0.71 and the dominance index ranged from 0.14 to 0.25, suggesting the absence of any significantly dominant species. Environmental conditions at the study site were generally favorable for macrofungal growth. Most of the identified macrofungi functioned as decomposers, several species had potential as food sources, and one species was identified as a potential pathogen of oil palm plants.

Abstract

Litter is an important component of forest ecosystems that plays a significant role in nutrient cycling, humus formation, and carbon storage. The Arboretum Forest of the University of Riau possesses diverse tree vegetation with the potential to produce substantial amounts of litter; however, information regarding its litter production rate remains limited. This study aimed to analyze the tree litter production rate in the Arboretum Forest of the University of Riau. A quantitative descriptive method was employed through direct observations at three sampling stations: shaded, transitional, and open areas. The collected litter data were analyzed to determine litter production rates based on the dry weight of the litter produced. The results showed that the tree litter production rate in the Arboretum Forest of the University of Riau was 282.8 g/m²/week, equivalent to 147.05 tons/ha/year. The transitional station exhibited the highest litter production rate at 175.02 g/m²/week, followed by the shaded station at 72.06 g/m²/week and the open station at 35.72 g/m²/week. Leaves were the dominant litter component, contributing a total production of 230.23 g/m²/week. These findings indicate that vegetation characteristics and environmental factors influence litter production within the arboretum forest ecosystem.

Abstract

Putat seeds (Barringtonia conoidea Griff.) are a local biological resource with the potential to be utilized as a natural ingredient in liquid soap production due to their presumed saponin content, which can generate foam and exhibit antibacterial properties. However, their application as a raw material for liquid soap remains relatively unexplored. This study aimed to evaluate the characteristics of liquid soap perlakuanted with putat seed extract at different concentrations. An experimental method was employed using four treatment concentrations of putat seed extract: 0%, 5%, 7%, and 9%. The observed parameters included pH, homogeneity, foam height, organoleptic properties, and irritation potential. Data were analyzed descriptively and quantitatively using the average values of each parameter and compared with the quality standards for liquid soap. The results showed that all perlakuantions had pH values ranging from 8.3 to 10 and met the required liquid soap quality standards. All perlakuantions were homogeneous, with no evidence of clumping or phase separation. The addition of putat seed extract increased both foam height and foam stability, with the 9% perlakuantion producing the highest foam height of 105 mm and foam stability of 92.67%. In general, increasing concentrations of Barringtonia conoidea Griff. seed extract positively influenced the physical characteristics of the liquid soap, particularly in terms of foam height and pH. Therefore, Barringtonia conoidea Griff. seed extract has been proven to be utilizable as a natural ingredient in liquid soap perlakuantion with physical characteristics that meet the quality standards of SNI 2588:2017.
