Plant morphology learning is an essential aspect of biology education that enables students to recognize various plant forms and structures. However, many students find it challenging to grasp this concept due to teaching methods that are less contextual and engaging. Nicotiana tabacum L., or tobacco plant, offers potential as a learning resource for plant morphology to facilitate students’ understanding. This study aims to explore the use of Nicotiana tabacum L. as a learning resource in plant morphology education. The research employs a descriptive qualitative approach by analyzing the morphological characteristics of Nicotiana tabacum L. and their elaboration. The findings indicate that this plant possesses various easily identifiable morphological features, such as large lance-shaped leaves, an upright stem, and a taproot system. The study concludes that Nicotiana tabacum L. serves as a contextual learning resource to deepen students' understanding of plant morphology. The use of this plant in teaching is expected to enhance students’ interest and engagement in studying biology, particularly in understanding plant structures. ABSTRAKPembelajaran morfologi tumbuhan merupakan aspek penting dalam pendidikan biologi yang memungkinkan peserta didik untuk mengenal berbagai bentuk dan struktur tumbuhan.

This study examined the effectiveness of the flipped classroom model in improving language proficiency among 20 fourth-grade elementary students at MI Miftahul Jannah, Kedung Supit. The flipped classroom approach allows students to independently review materials before class, maximizing in-class time for interactive and collaborative learning. Employing a qualitative research design with experimental pre-test/post-test components and descriptive methods, data were collected via observations and interviews. Analysis involved data reduction, presentation, and conclusion drawing. Language proficiency assessments and motivation questionnaires served as instruments. Results showed the flipped classroom significantly enhanced students' language abilities, particularly in speaking and writing, and fostered greater enthusiasm and engagement. The model’s implementation involved three phases: pre-class material review using worksheets; in-class discussions and exercises guided by the teacher; and post-class formative assessments. A notable improvement in listening and speaking skills was observed. Previously, students struggled with main ideas, new vocabulary, and expressing opinions due to time and improper language use. After adopting the flipped classroom, 15 of 20 students demonstrated significant progress, outperforming traditional methods. Furthermore, motivation questionnaires indicated increased student drive. This research confirms the flipped classroom as an effective strategy for boosting elementary language proficiency and offers a valuable resource for innovative teaching practices.

Korosi menjadi salah satu permasalahan pada industri, terutama pada perpipaan yang mengalami kerusakan karena korosi. Dengan penambahan green corrosion inhibitor yang akan mengurangi laju korosi pada baja. Green corrosion inhibitor digunakan sebagai alternatif dengan memanfaatkan senyawa tanin. Selain murah dan aman dalam penggunaannya, ketersediaan bahannya juga mudah ditemukan dalam kehidupan sehari-hari. Tujuan penelitian ini adalah mengetahui efisiensi daya hambat laju korosi pada pipa baja karbon dengan menggunakan ekstrak daun jambu biji dan daun sirsak. Ekstrak daun jambu biji dan daun sirsak diperoleh dengan cara maserasi kemudian hasil ekstrak didistilasi. Metode pengukuran laju korosi menggunakan weight loss. Spesimen baja karbon yang sudah dipotong kemudian direndam pada air laut dengan dan tanpa ekstrak daun jambu biji dan daun sirsak, dengan perbandingan konsentrasi 0%; 25%; 50%; 75%; dan 100% dengan masa perendaman selama 720 jam. Hasil penelitian didapatkan bahwa konsentrasi variabel dari daun jambu biji dan daun sirsak yang optimal pada penambahan konsentrasi inhbitor korosi sebesar 100%. Hasil penelitian adalah bahwa laju korosi terendah dari ekstrak daun jambu yang diperoleh yaitu 0,049 mm/tahun sedangkan untuk ekstrak daun sirsak laju korosi terendah yang dihasilkan yaitu 0,091 mm/tahun dengan konsentrasi penambahan 100%. Nilai efisiensi inbitor terbaik pada daun sirsak yaitu 79,63 % sedangkan efisiensi daun jambu biji terbaik yaitu 86,21 % pada konsentrasi penambahan ekstrak 100%.

Patchouli (Pogostemon cablin Benth.) is a significant tropical bioresource known for its essential oil, which possesses high ethnobiological and economic value but cannot yet be synthetically produced. This study aims to establish an in vitro conservation framework and evaluate the preservation of secondary metabolites (volatile oil) within callus cultures. Leaf explants were cultured on Murashige and Skoog (MS) media supplemented with various combinations of 2,4-D and BAP: 1 ppm BAP (W1), 1 ppm BAP + 1 ppm 2,4-D (W2), 1 ppm BAP + 2 ppm 2,4-D (W3), 2 ppm BAP + 1 ppm 2,4-D (W4), and 2 ppm BAP + 2 ppm 2,4-D (W5). The results indicated that W1 (1 ppm BAP without 2,4-D) was the most effective treatment for sustainable biomass production, achieving a 75% growth rate, the fastest induction time (6 days), and the highest fresh weight (0.1364 g). Thin Layer Chromatography (TLC) profiling confirmed that the in vitro callus successfully preserved volatile oil components identical to the mother plant, as evidenced by purple spots at Rf values of 0.75 and 0.95. Although alkaloids and flavonoids were not detected due to the cellular dedifferentiation phase, the consistent presence of volatile oils demonstrates the potential of in vitro systems for the conservation and sustainable management of tropical aromatic plant metabolites.

Sulawesi Island is a key area of the Wallacea region, known for its high level of plant endemism, including the genus Pogostemon. A comprehensive taxonomic study is essential to document the biodiversity and provide accurate identification for tropical resource management. This study aims to examine the taxonomic characters of Pogostemon spp. collected from Sulawesi and deposited at Herbarium Bogoriense (BO). Using a descriptive method based on morphological characteristics of 13 collection numbers, the study analyzed vegetative and reproductive structures. The results identified two distinct species: Pogostemon cablin (Blanco) Benth. and Pogostemon auricularius Hassk. These species are clearly distinguished by the shape of the leaf blade, calyx structure, and the type of indumentum present on the stem, leaf, and flower surfaces. This taxonomic study contributes to the baseline data of Lamiaceae in Sulawesi, supporting further research in plant ecology and conservation of tropical flora
