Abstract

Plant tissue culture is a technique for growing plant parts in vitro under sterile conditions, either in the form of cells, tissues, or organs. The purpose of the study was to determine the application of bioethical principles in making tissue culture media in a tissue culture laboratory in one of the agricultural institutions in Medan City. The method used in this research is descriptive qualitative. The results of the analysis show that this laboratory has applied bioethical principles in the process of making tissue culture media. The bioethical principles applied include safety and health, resource conservation principles, quality assurance principles, and information disclosure principles.

Abstract

This research aims to determine the effectiveness of the genjer plant (Limnocharis flava) in absorbing phosphate pollutants contained in laundry wastewater and to identify environmental factors that influence the effectiveness of the genjer plant (Limnocharis flava) in absorbing phosphate pollutants from laundry wastewater. The study was conducted in the Greenhouse of the Biology Department, Universitas Negeri Medan, using the constructed wetland method with variations in laundry wastewater concentrations (25%, 50%, 100%) and clean water as the control. The sample was taken from a laundry business on Jl. Tuasan, Medan City. Over 7 days of observation, parameters such as pH, temperature, turbidity, and the physical condition of the genjer plants were monitored. The results showed that genjer plants were effective in absorbing phosphate, with reduced turbidity and stabilized pH and temperature, with the 50% concentration treatment being the most optimal. This research is expected to serve as a reference for the application of phytoremediation technology using genjer plants (Limnocharis flava) as an environmentally friendly alternative for laundry wastewater treatment

Abstract

Pollinator insects have an important role in the success of plant reproduction, but information on the diversity of pollinating insects in guava plants in Tanjung Anom Village is still limited. This study aims to determine the diversity, dominance, distribution pattern, and differences in the presence of potentially pollinating insects in guava plants (Psidium guajava L.) between morning and evening in Tanjung Anom Village, Pancur Batu District, Deli Serdang Regency. The research was carried out from June to August 2025. The selection of sample trees was carried out by purposive sampling, while the observation of pollinating insects used the scan sampling method which was carried out four times with an interval of one week in the morning and evening. The results of the study show that there are nine species of insects with potential pollinators that belong to three orders and four families. The level of diversity is classified as moderate (H' morning = 1.80; H' afternoon = 2.08), while the dominance level was low (C morning = 0.16; C afternoon = 0.11). Distribution pattern analysis showed that five species had a grouping pattern, namely Ischiodon scutellaris, Apis cerana, Tetragonula laeviceps, Xylocopa confusa, and Nomia sp., while four species showed a uniform distribution pattern, namely Anomala sp., Eumerus sp., Apis dorsata, and Xylocopa latipes. The results of the t-test showed a significant difference in the presence of pollinating insects between morning and evening with a p value of < 0.05. These findings show that the difference in the time of daily activity affects the structure of the pollinating insect community in guava plants. Therefore, the results of this study can be used as the basis for agroecosystem management, especially in the regulation of cultivation practices to increase pollination effectiveness and plant productivity.
