Abstract

This article aims to observe the effect of hypertonic sucrose solution concentration on plasmolysis of epidermal cells of Rhoeo discolor leaves. Plasmolysis occurs when plant cells lose air due to the surrounding hypertonic solution, which causes the cytoplasm to shrink and the plasma membrane to detach from the cell wall. In this experiment, Rhoeo discolor leaves were immersed in sucrose solutions with different concentrations (0.14 M to 0.26 M) for 30 minutes, and the percentage of plasmolyzed cells was calculated. The results showed that the higher the sucrose concentration, the more cells underwent plasmolysis. At low concentrations (0.14 M and 0.16 M), plasmolysis occurred at a small percentage (1.77% to 7.25%), while at high concentrations (0.24 M to 0.26 M), the percentage of plasmolyzed cells increased significantly, reaching 3.03% at a concentration of 0.26 M at the 30th minute. In addition, prolonging the immersion time to 30 minutes caused a decrease in the number of plasmolyzed cells, indicating that osmotic equilibrium was reached after a certain time. Overall, this study confirms that hypertonic environmental concentration has a direct effect on plant cell plasmolysis, with the intensity increasing with higher environmental concentrations.

Abstract

Garut is one of the areas that has local cultural wisdom that is still beautiful and preserved. The diversity of existing plants has sufficient economic value and has potential as alternative ingredients and medicines. The people of Garut still cultivate and use plants as alternative medicines that can cure various diseases. The Mustajab plant or Gedi Leaf with the scientific name Abelmoschus manihot of the Malvace family is one of the herbal plants that has long been used by the people of Sindangsari village as a fever reducer or pyretic in babies. Pyretics is a condition in which the body experiences an increase in temperature above normal limits due to a response to infection or inflammation. This research was conducted in Sindangsari Village, Leuwigoong District, Garut Regency. The method used in this research is an exploratory survey method. The data collection technique uses a purposive sampling method. This research data analysis uses qualitative and quantitative methods. To calculate the use value, the UV method is used. Apart from that, the Fidelity Level Index (FLI) method is also used. Mustajab leaves are included in the category of plants with metabolite compounds which can produce compounds from the soil itself. Mustajab leaves can cure fever in babies because they contain many active compounds, one of which is flavonoid compounds. Based on the results presented in the table, it can be seen that the highest FL value is in the mustajab plant which is used as a treatment for fever in babies with a FL value of 51.5%. Based on the results table, it can be seen that the highest UV value is in the use of mustajab leaves as a medicine for baby fever with a UV value of 0.51. There are many processing and application methods for using mustajab leaves as traditional medicine, including boiling, squeezing and pounding. Based on the data above, it can be concluded that mustajab leaves are one of the traditional food plants which are usually used by rural communities as an alternative medicine to reduce fever in babies.

Abstract

This study aims to analyze the implementation of observational activities conducted by students of Qur’anic Sciences and Tafsir (IAT) in Qur’anic da’wah activities at Darul Ihsan Modern Islamic Boarding School. The focus of the study is directed at the forms of da’wah activities, the methods of delivering the material, and the responses of the students (santri) to the presence of university students acting as young preachers who are directly involved in the process of religious guidance within the boarding school environment. The method used in this study is a qualitative approach employing field observation techniques, in-depth interviews with relevant parties, and documentation as supporting research data. The results of the study indicate that IAT students are able to integrate their understanding of tafsir with a contextual communicative approach, making the Qur’anic material easier for students with different levels of ability to understand. The da’wah activities include thematic religious studies, tahsin and tahfiz of the Qur’an, Islamic discussions, and the development of students’ morals and character in their daily lives. The main supporting factors are the support from the boarding school authorities, a conducive learning environment, and the academic readiness of the students. Meanwhile, the obstacles encountered include limited time for implementing the activities and variations in students’ abilities to comprehend the material. In general, this observation provides valuable practical experience for students in applying the theory of Qur’anic da’wah while also strengthening the synergy between higher education institutions and Islamic boarding schools in developing sustainable Qur’an-based da’wah.
