The use of synthetic pesticides in the agricultural sector remains the primary choice for farmers in Indonesia due to their high effectiveness, but their massive use has negative impacts on human health and the environment. Therefore, there is a need for environmentally friendly and sustainable pesticide innovations. Red onion peel waste with the addition of TiO₂ nanotechnology is a strategic development step as a solution to the dangers of synthetic pesticides. Red onion peel contains bioactive compounds such as acetogenin, squamocin, gibberellin, cytokinin, and abscisic acid, which have the potential to be natural pest control agents. The process of making organic pesticides is carried out through the maceration of onion skins, followed by the addition of TiO₂ nanoparticles that act as photocatalytic catalysts to increase pesticide effectiveness and degrade synthetic pesticide residues. The development of these organic pesticides is in line with the principles of Green Chemistry, particularly designing safer chemicals, catalysis, design for degradation, and real-time pollution prevention. Through the implementation of strategic steps such as research, testing, socialization, and continuous evaluation, TiO₂ nanotechnology-based organic red onion peel pesticides have the potential to become a safe, effective, and environmentally friendly alternative in supporting sustainable agriculture in Indonesia.

This study investigates the effect of adding onion peel extract as a corrosion inhibitor on the corrosion rate and hardness of radiator pipes. The research employed an experimental method with inhibitor concentrations of 0 ppm, 100 ppm, 200 ppm, and 300 ppm.

Eleutherine bulbosa (Mill.) and Allium cepa L. (including garlic and onion peel) are medicinal plants that have long been traditionally used to treat cancer, diabetes, hypertension, infectious diseases, and inflammation. Recent scientific studies emphasize the importance of extract standardization to ensure consistent quality, safety, and efficacy. Standardization includes specific parameters—such as organoleptic identification, water- and ethanol-soluble extract values, phytochemical profiles, and determination of marker compounds—and nonspecific parameters such as moisture content, loss on drying, total ash, and acid-insoluble ash. Ethanol extract of E. bulbosa showed moisture and drying loss values below 10%, total flavonoid content of around 1.2%, and positive phytochemical tests for alkaloids, flavonoids, saponins, and quinones. Onion peel extract contains a high flavonoid content (7.84 mg QE/g) with moderate antioxidant capacity (DPPH IC₅₀ 152.65 µg/mL), while fermented garlic (black garlic) contains more than 12% polyphenols and more than 2% flavonoids, as well as a high level of S-allyl-L-cysteine (SAC) as a stable bioactive compound. The pharmacological activities of these standardized extracts include strong antioxidant effects, α-glucosidase inhibition for antidiabetic activity, induction of apoptosis and anti-angiogenesis as anticancer potential, membrane disruption and enzyme inhibition for antimicrobial activity, as well as COX/LOX modulation for anti-inflammatory effects. These activities are directly correlated with the secondary metabolite composition of each material. With their phytochemical richness and diverse biological activities, E. bulbosa and A. cepa have great potential as raw materials for standardized herbal products. Further in vivo studies and clinical trials are needed to validate their therapeutic efficacy and to support the development of evidence-based phytopharmaceuticals.

The community service activity through KKN 15 UMRAH in Tanjung Uban Selatan Village, Bintan Regency, aims to emphasize the product identity of the KUBE Sejahtera MSME through packaging label design. This MSME previously experienced marketing problems due to simple, unattractive product labels that did not meet BPOM standards, making it difficult for consumers to recognize and compete in the formal market. KUBE Sejahtera consists of ten members offering various types of food products such as banana chips, potato chips, onion cuttings, cookies, and peyek. A participatory approach was implemented so that KUBE members not only received results but also actively participated starting from identifying problems, discussing needs, to designing labels using a simple application. The results of the activity showed an increase in members' understanding of the importance of labels as a marketing strategy, as well as the birth of new label designs that are more attractive, professional, and in accordance with regulations. Various products successfully developed new visual identities with more prominent names and appearances, such as Ketas Potato Chips, MaYure Sejahtera Onion Cuttings, Kerpi'la, and Suka-Suka Peyek. This change has had a positive impact, marked by increased member confidence in selling products and broader opportunities to expand market reach. Overall, this program demonstrates that simple interventions through label design can increase the competitiveness of local products and serve as an effective strategy for empowering MSMEs. It is hoped that this success can be emulated by other business groups to support sustainable community economic growth.

This study also highlights the importance of education and training for farmers to improve their technical skills in farming and managing their farms. Training in the use of modern agricultural technologies, such as automated fertilizing tools and efficient irrigation systems, can help farmers reduce production costs and increase yields. Furthermore, training in digital marketing can help farmers market their products more effectively through online platforms, reducing reliance on intermediaries and increasing profit margins. Furthermore, it is crucial for the government to provide support in the form of extension services and easy access to business capital. More accessible capital will enable farmers to invest in more efficient equipment and more environmentally friendly organic fertilizers. Targeted microcredit distribution to farmer groups can also accelerate the adoption of new, more productive agricultural technologies. The adoption of sustainable and environmentally friendly agricultural practices should be a long-term focus to ensure the registration of shallot farming businesses. Farmers need to be incentivized to use organic fertilizers and natural pesticides that are safer for the soil and air. Furthermore, the implementation of integrated and environmentally friendly farming systems such as agroforestry can also be an alternative to increase agricultural yields without damaging the environment. With improvements in education, training, access to capital, and the adoption of more efficient technology, shallot farming in Pasir Village can develop better and become more sustainable in the future. Furthermore, collaboration between farmer groups and local research institutions and universities can also be key to introducing new agricultural innovations.

This study aims to observe the phases of mitosis in the meristem cells of shallot roots (Allium cepa) through microscopic observation as part of the Cell Biology learning model. Mitosis is an important part of the cell cycle that plays a role in growth, tissue repair, and asexual reproduction in organisms. A deep understanding of the mitosis process is an important foundation in various branches of biology, including genetics, biotechnology, and histology. Shallot roots were chosen because they have actively dividing meristem tissue at the root tip,as well as a large and transparent cell structure that facilitates the staining and observation process. Preparation was carried out by soaking the onion roots in a solution of acetic acid and alcohol for fixation,then staining with acetocarmine acid so that the chromosomes are clearly visible. The process of crushing the root tip and pressing it on a glass object (squash method) was used to expand the observation area. A light microscope with a magnification of 400x and 1000x was used to identify the division phases. Observation results show the presence of all phases of mitosis, namely prophase (nucleolus and nuclear membrane begin to disappear,chromosomes condense), metaphase (chromosomes line up at the equator), anaphase (chromatids separate to opposite poles), and telophase (nuclear membrane and two daughter cell nuclei re-form). Visual documentation in the form of microscopic photographs and descriptive tables clarify the identification of these phases, thus facilitating student understanding.From a pedagogical perspective, this microscopic practicum-based learning has been proven to improve students' observational skills, laboratory skills, and conceptual understanding of cell division. Students not only memorize theories, but directly experience the scientific process through exploration and discussion of observation results. Evaluation of learning outcomes is carried out through post-practicum quizzes and student worksheets, showing an increase in understanding scores of more than 30%.

The growth of the snack food industry in Indonesia encourages MSME actors to innovate in improving product competitiveness, including through packaging development. UMKM Nambawang, as a producer of fried shallots, faces challenges in packaging design that lacks visual appeal and does not reflect the product’s identity, despite its superior taste quality. This study aims to design more functional, economical, and competitive fried shallot packaging by integrating the Quality Function Deployment (QFD) and Value Engineering (VE) methods. QFD is applied to translate consumer needs (voice of customer) into technical packaging attributes, while VE is used to evaluate the performance and cost-efficiency of design alternatives. The analysis results indicate that key attributes prioritized in packaging development include color aesthetics, product protection, ease of opening and resealing, clarity of product information, and storage convenience. These main attributes are translated into technical elements such as the use of standing pouches, zipper locks, full-print designs, added onion illustrations, and complete product information. The application of QFD and VE methods results in a mockup visually appealing, functional, and durable packaging design, enhancing the product’s added value based on consumer needs and increasing its competitiveness in the domestic market.

This study aims to analyze the determination of selling prices and enthusiasts by traders and their relationship with demand fluctuations in the traditional market of MMTC Medan. The method used is a qualitative descriptive analysis method with a survey approach, involving three traders, namely rice, onion, and cabbage traders, data collected through direct interviews. The results of the study show that the setting of selling prices by traders has an effect on market enthusiasts as well as fluctuations in demand. Merchants set prices based on a combination of cost of goods sold, competitor prices, and estimated consumer purchasing power. Significant price fluctuations tend to lower the volume of demand, especially in non-primary products, and also poor quality of goods. Thus, this study concludes that understanding demand patterns and price adaptability are the main key factors in maintaining the business continuity of traders in the traditional market of MMTC Medan.

Food is a basic need that must be met by every individual. In Indonesia, rice is still the main staple food, but the shift in consumption to rice and wheat which are imported foodstuffs raises concerns about food security. Therefore, the development of local food alternatives such as MOCAF (Modified Cassava Flour) flour from cassava is important. In this practicum, MOCAF flour was made through a cassava fermentation process, followed by making onion cakes using the MOCAF flour. Organoleptic tests and XRF tests were carried out to evaluate the quality of MOCAF flour. The results of the practicum showed that the substitution of MOCAF flour in making onion cakes can produce low-gluten products that have the potential to be a sustainable food alternative.

This study aims to analyze the environmental impact of daily activities at the Sukomoro Red Onion Market, Nganjuk, and to formulate a sustainable environmental management strategy.
