Abstract

Tempeh is an affordable source of plant-based protein for the community. The fortification of tempeh with coriander (Coriandrum sativum), garlic (Allium sativum), and cardamom (Amomum cardamomum) is important to study because these three spices contain bioactive compounds that potentially increase the protein content and nutritional value of tempeh. This research is necessary to scientifically examine the effect of spice fortification on tempeh protein levels as an effort to develop functional food. The testing method used in this study was the Kjeldahl method referring to SNI 01-2891-1992. Tempeh fortification with coriander showed the most significant increase in protein content, reaching 7.03%, compared to tempeh without spices, garlic, and cardamom, which only increased protein content to 2.74%, 2.92%, and 3.94%, respectively. This is due to the high protein content in coriander, approximately 17-20% per 100 grams of material, which significantly enriches the protein content of tempeh. In contrast, garlic and cardamom have lower protein content, around 6-7% and 9-11% per 100 grams of material, making their contribution to increasing tempeh protein content less significant. This research demonstrates that the use of coriander as a fortification ingredient can be an effective strategy to enhance the nutritional value and protein content of tempeh, making it a more functional and nutritious choice for consumers.

Abstract

The purpose of this study is to identify the diversity of butterfly species as a potential object for ecotourism development in the TWA Suranadi and to develop an animal ecology e-module. This research is a descriptive exploratory study. Data collection was conducted using survey techniques, and samples were taken using Purposive Random Sampling by dividing the TWA Suranadi area into four transects (water transect, left transect, middle transect, and right transect). Butterfly collection was carried out using the sweeping technique implemented randomly. The development of the animal ecology module was designed using the 4D model (Define, Design, Develop, and Disseminate). The Develop phase was limited to expert validation to assess the content validity and construct validity of the animal ecology e-module. The results showed that butterfly diversity varied across the observation transects. The Middle Transect dominated with a high distribution percentage of 56.25%, followed by the Water Transect at 23.43%, the Left Transect at 15.62%, and the Right Transect with the lowest distribution percentage at 4.7%. Ecological analysis results indicated a species diversity index across the four research locations ranging at 2.341 (Moderate Diversity), an evenness index ranging from 0.152 (Low Evenness), and a dominance index of 0.108 (Low Dominance). Expert validation results showed that the content validity of the animal ecology e-module had an index of 0.880, categorized as very valid, while the construct validity, which included the feasibility of presentation, had an index of 0.902, categorized as very valid, and the feasibility of language aspect averaged at 0.770, categorized as valid.

Abstract

Dental caries is a disease of hard tissue caused by the activity of acid-producing bacteria that ferment carbohydrates after human consumption caused by the bacteria Streptococcus mutans. The flavonoid content in celery leaves and the tannin content in guava leaves can be used as an antibacterial treatment. Pharmaceutical preparations that can be used to treat dental caries problems are mouthwash. This research aims to formulate a combination of celery leaf and guava leaf extracts into a mouthwash preparation as an antibacterial against Streptococcus mutans. The research method used was experimental by testing the antibacterial activity of Streptococcus mutans in vitro. The results of the study showed that (1) the results of the antibacterial activity test on the negative control mouthwash were that the mouthwash base had no inhibition zone (2) the positive control chlorhexidine had an inhibition zone of 14.27mm (3) with a comparison between celery leaf extract and guava leaf extract 1:3 seeds, the results obtained were that the diameter of the inhibition zone at 20% concentration was 10.20 mm, 40% concentration was 11.20 mm, and 60% concentration was 12.05 mm; (4) The inhibitory power against Streptococcus mutans bacteria of the mouthwash containing a combination of celery leaf extract and guava leaf extract is greater than the inhibitory power of the positive control.

Abstract

Digital literacy is important for every student to have. Digital literacy needs to be trained and learned to form a young generation that is digitally literate so that they are ready to participate in the digital community with confidence in communicating, sharing and distributing knowledge in a useful and efficient way, provides readiness to adapt successfully to a changing work environment and increasing self-control as a solution to the spread of false information that continues to repeat itself and is increasing in number. This research aims to measure students' digital literacy at SMAN 1 Kesesi. The methods used were filling out questionnaires and conducting interviews. Seventy-six eleventh-grade students of SMAN 1 Kesesi, Pekalongan Residence, Central Java, Indonesia, and two biology teachers were selected as the research sample in this study. The research results showed the following aspects: Firstly, the student's digital literacy questionnaire is 71%, which is classified as moderate in digital literacy indicators including finding, using sources, selecting, evaluating, considering sources, message effects, and using data to produce work; secondly, some of the things that teachers do to train these two skills are by inviting students to search for information via Google/search engines and video searches to support the teacher's explanations and using Canva to make some presentation. Unfortunately, teachers do not train them on how to search using appropriate keywords and trusted sources. Finally, teachers must be more active and innovative in maximizing the wise use of digital media to improve students' digital literacy.

Abstract

Orchids are ornamental plants that have high aesthetic value and beauty. Many human activities use this plant, including weddings, Christmas, New Year and birthdays. Orchid propagation can be done conventionally, but it requires a large area of land and takes a long time to grow. However, it can also be multiplied using tissue culture. Plant tissue culture techniques have better prospects than conventional propagation because tissue culture can produce large numbers of new plants without being influenced by time or season. This research aims to determine the effect of IAA and leaf order on shoot growth of Cattleya sp orchid plants. This type of research is experimental research with a Factorial Completely Randomized Design (CRD) with 12 treatments and 3 replications. There are 2 factors in this study, namely factor I PGR IAA (0, 0.5 mg/l, 1 mg/l, and 1.5 mg/l) and factor II Leaf order (1st leaf, 2nd leaf, and 3rd leaf). This research is a quantitative descriptive study with the parameters of the time of shoot emergence and using 2-way Statistics with Analysis of Variance (ANOVA) with the parameters of number of shoots, number of leaves (strands), and plantlet height. From the research results, it was found that the administration of IAA (Indole Acetic Acid) and the order of the leaves did not have a real effect on the number of shoots, number of leaves (strands) and plantlet height. However, the best treatment is the I0.5D2 treatment (IAA 0.5 mg/l and 2nd leaf).
