Abstract

Fruit quality is an important factor in selecting fruit for consumption because it affects consumer health and satisfaction. Identification of fruit quality has become the focus of research, and one of the approaches used is a non-destructive approach through measuring the gases produced by the fruit. Machine learning can be used to process this gas data and build system models that can classify fruit quality. This research discusses the application of the DCS-OLA and Stacking dynamic ensemble learning algorithms to build a fruit quality detection system model. The basic methods used to build models are Logistic Regression, Decision Tree, Gaussian Naïve Bayes, and Mul-ti-Layer Perceptron. The fruit used is mango with a shelf life of 7 days and Srikaya (sugar apple) with a shelf life of 4 days. The condition of the initial dataset is unbalanced. The research results show that trimming the mango dataset to only 4 days according to the shelf life of sugar apple helps reduce the difference in shelf life between the two. Then jittering and balancing techniques are used to increase and balance the number of datasets between the two types of fruit. High accuracy is achieved by the DCS-OLA ensemble and stacking ensemble by combining the basic methods of Logistic Regression and Decision Tree, especially in balanced dataset conditions. In conclusion, the use of ensemble learning in detecting fruit quality has great potential for real-world applications. However, further validation is needed with larger datasets and a wider variety of conditions.

Abstract

This study aims to determine the physical feasibility of toner preparations from Chinese betel leaf extract (Peperomia pellucida) with variations of polysorbate 20 surfactants through organoleptic tests. Toner is a form of liquid cosmetic preparation used to cleanse, refresh, and balance the pH of the skin. Chinese betel leaf extract contains active compounds such as flavonoids, tannins, and saponins that function as antibacterials and anti-inflammatory agents. Polysorbate 20 is used as a nonionic surfactant that plays a role in maintaining the clarity and stability of the solution. This study used an experimental method with a quantitative approach. Three toner formulations were prepared, namely F1 (without extract and containing 5 mL of polysorbate 20), F2 (5 grams of extract and 5.5 mL of polysorbate 20), and F3 (7.5 grams of extract and 6 mL of polysorbate 20). Organoleptic tests were carried out by expert panelists (two beauty lecturers and one doctor) based on color, aroma, and texture parameters. The test results showed that F1 had a clear color and was odorless, while F2 and F3 had a brownish green color and a distinctive aroma of Chinese betel leaves. All three formulations had a liquid texture. The highest organoleptic test score was obtained by F3 (83.33) which indicated that the formulation with the highest concentration of extract and surfactant provided the best visual and sensory impression. The conclusion of this study indicated that F3 was the most physically feasible formulation based on organoleptic evaluation. This study contributes to the development of local herbal cosmetics that are stable and sensorially preferred.

Abstract

This study aims to compare the effectiveness of hybrid learning and fully online learning in enhancing students' critical thinking skills. The research employs a quasi-experimental design with a nonrandomized control group and pretest-posttest approach, involving 90 sixth-semester students from the Family Welfare Education Study Program at Semarang State University. Participants were divided into two groups: hybrid learning and fully online learning, with 45 students each. The instruments used included validated and reliable critical thinking tests and open-ended questionnaires to gather data on learning experiences. Data analysis utilized descriptive and inferential statistics, including paired t-tests and independent t-tests, with preliminary normality and homogeneity assessments. The results indicate significant improvement in critical thinking skills with both learning methods, but hybrid learning showed a more substantial increase in scores (p < 0.000) compared to fully online learning (p < 0.006). Thus, hybrid learning is more effective in fostering critical thinking skills, underscoring the benefits of combining face-to-face and online learning for optimal student development.

Abstract

Community service focused on product creation and development, exceptionally functional leather craft products such as shoes, wallets, and bags, holds great promise. Integrating eco-print motif creation within these leather crafts is strategically significant. It enhances the production of these crafts and contributes positively to the economy of Faro Leather Craft artisans in the Bumirejo Mungkid Magelang foster village. One of the main challenges the artisans face is the lack of potential for creating new, varied, and dynamic motifs, especially considering their beginner level of expertise in leather craft creation. Therefore, there is a need for innovations that are easy to implement. The solution proposed through this community service involves mass production of leather crafts using eco-print techniques, thereby increasing production. This approach also involves applying and utilizing science and technology for the benefit of Magelang village, positioning it as a foster partner of Unnes. It aims to provide new insights into creating motifs with environmentally friendly innovative tools. Additionally, this innovation is targeted at artisans, including the younger generation, to foster a love for batik while focusing on the regeneration and development of batik in the Bumirejo Mungkid Magelang village. To achieve these goals, the community service project involves creating eco prints on leather craft products for use by artisans, artists, and new entrepreneurs. The initiative includes both new and existing artisans interested in participating as tenants. The project activities encompass execution, material exploration, form experimentation, and motif understanding. This includes the creation and motif development process using eco-print techniques, data analysis, motif creation, copyright registration, and report compilation. The outputs of this community service include products from training sessions, scientific articles, copyrights, and reports. Additional outputs involve consumer feasibility testing, exhibitions, and mandatory outputs such as scientific articles, highlight videos, copyrights, and reports.

Abstract

Mangunsari Village, Gunungpati District, Semarang City, possesses significant potential in duck egg farming, yet the development of local salted egg businesses faces several constraints. Key challenges include a time-consuming conventional production process (10-15 days) with high risk of egg spoilage, limited product diversification and unattractive packaging, and insufficient knowledge and skills among the community regarding technology, simple financial management, and digital marketing. These conditions lead to low productivity, limited product value, and restricted market reach. This community service program was designed to provide comprehensive solutions through technology innovation and empowerment. The implementation methods included socialization, workshops, practical demonstrations, and intensive assistance focusing on operating the Salted Egg Oven Machine, developing product diversification (flavor variants and packaging), business cash flow bookkeeping, and digital marketing using social media and e-commerce platforms. The achieved results demonstrate the potential to drastically cut down salted egg production time to approximately five hours, successful development of at least two new flavor variants, and improved packaging designs. The partners also showed increased capacity in operating and maintaining the oven, conducting basic financial recording, and utilizing digital technology for promotion and sales. This program tangibly enhances production efficiency, added value, and potential market expansion, expected to positively impact the community's productivity and economic welfare. The service contributes to achieving the SDGs in supporting food security, inclusive economic growth, and sustainable production.
