Abstract

Membran plasma adalah lapisan tipis yang mengelilingi sel secara menyeluruh, terdiri dari lapisan ganda fosfolipid dengan protein tertanam, berfungsi vital dalam menjaga integritas sel serta mengatur pergerakan zat, dan memiliki struktur dinamis yang memungkinkan komponennya bergerak secara lateral dalam fluiditas membran.Tujuan dari penelitian ini untuk meningkatkan kreativitas dan inovasi dalam diri mahasiswa, mengasah kemampuan komunikasi dan kerjasama dalam kelompok belajar. Selain itu, penelitian ini dapat menambah pengetahuan dan wawasan mengenai membran sel serta mengetahui bagaimana kelarutan lipid dalam mebran mempengaruhi proses difusi dan osmosis. Metode penelitian menggunakan metode pengamatan dan perlakuan. Hasil penelitian menunjukka bahwa pengaruh garam yang dilarutkan dalam air sebanyak 50 ml pada kentang menunjukkan dampak yang signifikan terhadap berat dan tekstur jaringan kentang. saat teh dimasukkan ke dalam air panas, molekul air di sekitarnya memiliki energi kinetik yang tinggi, memungkinkan molekul-molekul teh yang larut untuk lebih mudah bergerak dari daerah dengan konsentrasi tinggi (teh yang belum larut) ke daerah dengan konsentrasi rendah (air). methanol lebih efektif dalam mempercepat reaksi dibandingkan dengan etanol, baik pada konsentrasi mutlak maupun setelah pengenceran menggunakan konsentrasi larutanKata Kunci : Permeabilitas Membran, Difusi, Osmosis, Kelarutan Lipid.   The plasma membrane is a thin layer that completely surrounds the cell, consisting of a phospholipid bilayer with embedded proteins, serves a vital function in maintaining cell integrity as well as regulating the movement of substances, and has a dynamic structure that allows its components to move laterally within the fluidity of the membrane. The purpose of this research is to increase creativity and innovation in students, hone communication skills and cooperation in study groups. In addition, this research can increase knowledge and insight into cell membranes and find out how lipid solubility in membranes affects the process of diffusion and osmosis. The research method used observation and treatment methods. The results showed that the effect of salt dissolved in water as much as 50 ml on potatoes showed a significant impact on the weight and texture of potato tissue. when tea is put into hot water, the surrounding water molecules have high kinetic energy, allowing the dissolved tea molecules to move more easily from the area of high concentration (undissolved tea) to the area of low concentration (water). methanol is more effective in accelerating the reaction compared to ethanol, both at absolute concentration and after dilution using solution concentration. Keywords: Membrane permeability, diffusion, osmosis, lipid solubility.

Abstract

Orchid mycorrhiza is a type of fungus that is able to associate well with orchid plants. Orchids require fungal hyphae infection at every phase of their growth and development. Mycorrhizal fungi provide the organic and organic nutrients needed by orchid planting. Meanwhile, orchid plants are suppliers because the results of photosynthesis of orchid plants are distributed in the body of fungi as an energy source. Given the importance of the prospect of mycorrhizal utilization for orchids, it is necessary to continue to develop studies on identification. The purpose of this study is to isolate, identify and characterize mycorrhiza in Dendrobium nobile orchids. The method used was with a descriptive design on the identified orchids, samples in the form of Dendrobium nobile orchid roots, the media used was PDA media, transverse and longitudinal root cut types.  The way it works includes sample preparation, media preparation, fungal isolation, fungal colony purification,

Abstract

Water is a natural resource that is important for life. However, many rivers in Indonesia experience pollution problems. One alternative for handling water pollution is to use phytoremediation plants such as kayu apu. The aquatic plant kayu apu (Pistia stratiotes L.) is known to have phytoremediation capabilities to clean up pollution. However, there is still little research that focuses on the influence of environmental factors on its capacity to improve water quality. Therefore, this research project aims to determine the ability of kayu apu as a phytoremediator in reducing the concentration of pollutants and improving water quality. The method used is a post-test only control group design. Water samples were taken in the Bantaran River, Madiun, then incubated with apu wood plants. The parameters tested include Ph, temperature and water condition (turbid/clear). The research results show that kayu apu is able to reduce the concentration of pollutants and improve water quality through a phytoremediation mechanism. It is hoped that this project can increase understanding regarding the potential of the kayu apu plant as a phytoremediator in efforts to preserve aquatic ecosystems and their biodiversity
