Abstract

This article presents an in-depth analysis of the polarity properties of polar and nonpolar covalent compounds found in various family medicinal plants, and explores their potential applications in health and the food industry. Covalent compounds, which are formed through the shared use of electron pairs between atoms, play an important role in determining the chemical and physical properties of a substance. This study used solubility and filter paper testing methods to identify the polarity of compounds in plant samples such as orange, lemon, tomato, spinach, and chili, which were found to be polar, and cinnamon, ginger, turmeric, galangal, and kencur, which showed nonpolar properties. These results suggest that polar compounds have the potential to be applied in products that require interaction with water, such as herbal drinks, while nonpolar compounds are more suitable for use in oil-based formulations, such as ointments or essential oils. A deeper understanding of the polarity characteristics of these compounds not only broadens scientific insights into medicinal plants, but also opens up opportunities for the development of innovative products in the pharmaceutical and food fields ABSTRAKArtikel ini menyajikan analisis mendalam terhadap sifat polaritas senyawa kovalen polar dan nonpolar yang terdapat pada berbagai jenis tanaman obat keluarga, serta mengeksplorasi potensi aplikasinya dalam bidang kesehatan dan industri pangan. Senyawa kovalen, yang terbentuk melalui penggunaan bersama pasangan elektron antar atom, memainkan peran penting dalam menentukan sifat kimia dan fisika suatu zat. Penelitian ini menggunakan metode uji kelarutan dan pengujian kertas saring untuk mengidentifikasi polaritas senyawa pada sampel tanaman seperti jeruk, lemon, tomat, bayam, dan cabai yang ditemukan bersifat polar, serta kayu manis, jahe, kunyit, lengkuas, dan kencur yang menunjukkan sifat nonpolar. Hasil penelitian ini menunjukkan bahwa senyawa polar memiliki potensi untuk diaplikasikan dalam produk yang memerlukan interaksi dengan air, seperti minuman herbal, sementara senyawa nonpolar lebih cocok digunakan dalam formulasi berbasis minyak, seperti salep atau minyak atsiri. Pemahaman yang lebih mendalam mengenai karakteristik polaritas senyawa ini tidak hanya memperluas wawasan ilmiah tentang tanaman obat, tetapi juga membuka peluang untuk pengembangan produk inovatif di bidang farmasi dan makanan berbasis bahan alami, yang semakin diminati oleh konsumen modern.

Abstract

Biology learning is essentially learning that always relates science to the environment and living things. Therefore, there is a need for learning media that contains local wisdom related to the surrounding environment. This study aims to determine the validity of the ethnogastronomy-based encyclopedia of Sambas Malay porridge and to determine student responses to the ethnogastronomy-based encyclopedia of Sambas Malay porridge. The research method used is R&D, in this study a 4-D development model is used, namely the define, design, development and disseminate stages, but in this development the researcher only reaches the development stage. This research was conducted on students of class X SMAN 1 Tekarang. The research instrument used was a questionnaire to obtain product validation and determine student responses to the developed product. Product validation was carried out by material experts, linguists, media experts, and student responses. The results showed that the encyclopedia developed was considered valid. The results of the material expert validator assessment were 93.81% (very valid), language experts were 86.67% (very valid), media experts were 95.00% (very valid). Student responses were obtained through 2 stages, namely small-scale trials of 72.58% (positive) and large-scale trials of 90.00% (very positive). Overall, it can be concluded that the encyclopedia developed is valid and gets a positive response from students.
