Abstract

Learning in the Economic Botany and Horticulture course is still dominated by lectures, resulting in limited student procedural skills and the absence of structured teaching materials. This study aims to develop and evaluate an eco-enzyme e-module to improve conceptual understanding, practical competence, and learning effectiveness. Using a Research and Development (R&D) approach with the ADDIE model, the study involved expert validation, a limited trial with one class, and pre-test/post-test assessment. Data was analyzed through descriptive validation scores, practicality ratings, and N-gain effectiveness. Results show that expert validation yielded very feasible scores for content (90%), media (88%), and instructional design (86%). The practicality test produced a very practical overall score of 87%, indicating high usability, readability, visual appeal, accessibility, and engagement. Implementation of the e-module increased students’ mean score from 62.4 (pre-test) to 91.2 (post-test), generating an N-gain of 0.77 categorized as high effectiveness. The e-module successfully integrates conceptual explanations, fermentation procedures, multimedia features, and project-based activities related to eco-enzyme production. In conclusion, the eco-enzyme e-module is valid, practical, and effective for supporting independent learning and enhancing students’ conceptual and procedural skills in accordance with the course learning outcomes.

Abstract

This study aims to inventory the plant species utilized by the local community as medicinal resources in Rano Village, Balaesang Tanjung Sub-district, and to examine their potential use as instructional learning media. The study employed a descriptive research design with a qualitative approach. Primary data were collected directly through interviews and field observations using a survey method with purposive sampling. Data collection techniques included direct observation, community interviews, and documentation of field findings. In the local context, a traditional healer (sando) plays a significant role as a key informant due to their extensive knowledge regarding the identification and use of medicinal plants. The results of the study revealed that the community utilizes 22 species of medicinal plants belonging to 14 plant families to treat various ailments, including rheumatism, asthma, hypertension, itching, scabies, cough, influenza, and several other health conditions. The plant parts used include leaves, stems, fruits, roots, bark, shoots, sap, and in some cases the entire plant. The preparation and utilization methods commonly practiced by the community include pounding, boiling, topical application, and direct consumption. Based on these findings, the documented information on medicinal plant utilization has strong potential to be developed as instructional media in the form of an educational e-book to support biology learning.

Abstract

This study aims to identify and describe the diversity of medicinal plants utilized by the community of Tindaki Village, South Parigi District, and to document their scientific names, morphological characteristics, plant parts used, and methods of preparation. The research employed a descriptive design with a qualitative approach using exploratory techniques. Data were collected through direct field observations conducted in six hamlets, structured interviews with ten informants consisting of five key informants and five supporting informants, and field documentation. Species identification was carried out through detailed observations of morphological characteristics, including roots, stems, leaves, flowers, and fruits. The identification results were subsequently verified using relevant scientific literature to ensure taxonomic accuracy. The findings revealed a total of 34 medicinal plant species belonging to 23 families and 18 orders. The plant parts most commonly utilized by the community were leaves and rhizomes, followed by fruits, roots, stems, and sap. These plants are traditionally used to treat various health conditions, including fever, cough, diarrhea, diabetes, hypertension, kidney stones, digestive disorders, and skin diseases. In conclusion, the results indicate that Tindaki Village possesses a high diversity of medicinal plants that continue to be actively utilized by the local community. Therefore, sustained conservation and systematic documentation efforts are essential to preserve this valuable ethnobotanical knowledge for future generations.

Abstract

This study aimed to identify and document the medicinal plant species utilized by the community in Bou Village, Sojol District, Donggala Regency, including their methods of preparation, the plant parts used, and the types of diseases treated. This research employed a qualitative descriptive design using the snowball sampling method. Data were collected through field observations, unstructured interviews with six informants who possessed traditional knowledge of medicinal plants, and direct documentation. The data were analyzed descriptively using a qualitative approach by describing the medicinal plant species identified, including their local names, scientific names, families, parts used, therapeutic uses, and methods of preparation. The results showed that 24 medicinal plant species belonging to 18 families were used to treat various ailments, most commonly fever, digestive disorders, urinary tract infections, coughs, and others. Leaves were the plant part most frequently used, while boiling was the most common method of preparation. This study highlights the importance of preserving local communities’ traditional knowledge regarding the use of medicinal plants as a form of local wisdom that has been passed down from generation to generation and should be sustainably maintained.

Abstract

This study aimed to determine the density of Hydrilla verticillata in Lake Talaga and to evaluate its potential as a bioindicator of changes in water quality caused by domestic pollution. The study was conducted at three stations, where physicochemical parameters were measured, including temperature, pH, light intensity, turbidity, dissolved oxygen, and the heavy metals Pb, Fe, and Cu. The results showed that water temperature ranged from 26 to 28°C and dissolved oxygen from 8.04 to 8.49 mg/L, indicating conditions that still support aquatic life. Heavy metal concentrations were below the established water quality standards. However, the pH was categorized as highly alkaline, and the highest turbidity was recorded at the station located near residential areas, suggesting environmental pressure associated with domestic activities. The density of Hydrilla verticillata varied among stations, reaching 607,333.3 ind/ha at Station II (high category), 180,000 ind/ha at Station I (moderate category), and 6,066 ind/ha at Station III (low category). The high density observed in the residential area indicates nutrient enrichment that may stimulate excessive growth of aquatic vegetation. This condition suggests symptoms of eutrophication and indicates that Lake Talaga is experiencing localized light to moderate pollution. Therefore, the density of Hydrilla verticillata has strong potential to be used as a bioindicator for assessing changes in water quality.
