Abstract

Butterflies are flower visitors and are important for plant pollinators. This research aimed to analyze the food plant preferences of butterflies and analyze the correlation between butterfly proboscis and flower corolla tube lengths.  Observations of butterflies were carried out at four locations within Dramaga campus area of Bogor Agricultural University from March to April 2024. The results showed 23 species of butterflies were observed on the flowers of eighteen plant species. Hesperiids and Nymphalids butterflies were found dominantly. The shrub plant, Lantana camara is the most visited by butterflies (8 species), followed by Saraca indica (6 species), and Turnera ulmifolia (5 species). Butterflies prefer to visit tubular shape and purple color of flowers. Based on the correlation analysis, there was no significant correlation between the butterfly proboscis and the flower corolla tube lengths.

Abstract

Jerawat adalah penyakit kulit yang disebabkan oleh beberapa faktor, salah satunya infeksi bakteri Staphylococcus epidermidis. Pengobatan dengan bahan alam sudah banyak dilakukan untuk mengurangi efek samping penggunaan obat anti-jerawat. Talas memiliki khasiat sebagai obat dan berpotensi sebagai antibakteri. Penelitian ini dilakukan untuk mengetahui aktivitas antibakteri ekstrak etanol 70% tangkai daun talas terhadap bakteri S. epidermidis dan senyawa bioaktif yang terkandung di dalamnya. Ekstrak dibuat dengan metode maserasi. Pengujian aktivitas antibakteri dengan metode difusi cakram dengan konsentrasi 0,5%; 1% ; 1,5%; 2%; dan 2,5% dengan klindamisin sebagai kontrol positif. Pengukuran zona bening atau diameter daya hambat (DDH) sebagai interpretasi data aktivitas antibakteri. Penapisan fitokimia meliputi alkaloid, flavonoid, saponin, terpenoid, steroid, dan tanin. Hasil pengujian aktivitas antibakteri menunjukkan terdapat zona bening pada semua konsentrasi kecuali 0,5%, dengan nilai rata-rata DDH masing-masing sebesar 17,33 mm; 20 mm; 25 mm; dan 27,67 mm. Nilai rata-rata DDH pada kontrol positif sebesar 47 mm. Berdasarkan penapisan fitokimia pada ekstrak etanol 70% tangkai daun talas memiliki hasil positif di semua uji. Ekstrak etanol 70% tangkai daun talas berpotensi sebagai antibakteri terhadap S. epidermidis dan memiliki senyawa-senyawa yang berpotensi sebagai bioaktif.

Abstract

Institut Pertanian Bogor merupakan kampus dengan biodiversitas tinggi dan kondisi ekosistem yang masih terjaga dengan baik. Banyak tumbuhan yang dijumpai, salah satunya tumbuhan paku epifit yang sangat melimpah jumlah dan jenisnya, tetapi informasi struktur reproduksinya masih terbatas. Penelitian ini bertujuan mengkarakterisasi struktur reproduksi tumbuhan paku epifit yang tumbuh di kawasan kampus IPB, Dramaga, Bogor. Tumbuhan paku epifit yang telah diperoleh diambil sorusnya dan diawetkan menggunakan alkohol 70%. Spora tumbuhan paku epifit diamati menggunakan mikroskop majemuk yang dihubungkan pada kamera optilab. Pengukuran spora tumbuhan paku dilakukan menggunakan aplikasi imageRaster v2.1 yang disajikan dalam bentuk gambar, tabel, kunci identifikasi, dan analisis deskriptif. Tumbuhan paku epifit yang diamati bervariasi pada susunan dan letak sorus serta ciri sporanya. Sorus berbentuk bulat dan garis. Sebagian besar sorus terletak pada tepi daun. Sebanyak 22 jenis tumbuhan paku yang memiliki spora bentuk monolete dengan laesura garis, satu jenis bentuk bulat, dan satu jenis bentuk tetrahedral-globose dengan laesura triradiate. Ukuran spora yang dijumpai yaitu medium, besar dan sangat besar. Semua spora memiliki nilai rasio P/E ≤1,00 dengan tipe peroblate, oblate, suboblate, oblate bulat dan prolate bulat. Permukaan perispora sangat beragam yaitu alate-angular, globules, shallow verrucae, verrucate, echinulate, tuberculate, rugate, globules, echinate, laevate, cristate, regulate, colliculate, granulose, dan costate-alate.

Abstract

Baduy indigenous plants have great potential as natural sources of bioactive compounds, yet scientific studies on their biological activities remain limited. This study aimed to evaluate the antioxidant, antibacterial activities, and total phenolic content of the leaves from four Baduy plant species: Gardenia jasminoides, Strobilanthes crispus, Ficus callosa, and Artocarpus camansi. The leaves were extracted with methanol, followed by fractionation using n-hexane and ethyl acetate. Antioxidant activity was assessed using DPPH and ABTS assays, total phenolic content was determined by the Folin–Ciocalteu method, and antibacterial activity was tested against Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, and Escherichia coli using the broth dilution method to determine Minimum Inhibitory Concentration (MIC). The results showed that the ethyl acetate fraction of A. camansi leaves exhibited the highest total phenolic content (23.53 mg GAE/g extract). This fraction demonstrated strong antioxidant activity in the ABTS assay (IC50 = 18.55 ppm) and moderate activity in the DPPH assay (IC50 = 50.67 ppm). Moreover, it showed strong antibacterial activity against S. aureus, B. subtilis, and P. aeruginosa. These findings indicate that A. camansi leaves possess promising potential as a natural source of antioxidant and antibacterial agents.

Abstract

Spent mushroom substrate (SMS) is a result of mushroom growing utilizing mushroom substrate media, such as substrate. Unhandled SMS garbage demands a subscription and poses an environmental risk. The SMS was obtained from oyster mushrooms (Pleurotus ostreatus) in Jonggol, Bogor, West Java, using a mixture of sawdust, lime, and bran. The purpose of this research was to examine the effects of using SMS as a planting medium and biofertilizer for the growth of maize (Zea mays), also on determining the optimum concentration of SMS as an anti-pathogen for the plant pathogens Fusarium oxysporum and Colletotrichum gloeosporioides. This research utilized a completely randomized design. The antifungal test results for SMS water extract against Fusarium oxysporum showed that the fungus was inhibited from growing at 60 to 100% extract concentrations. The use of SMS as a growing medium gave the best results on the growth of the number of plant leaves. Microscopic observation of the morphology of fungal pathogens Fusarium oxysporum and Colletotrichum gloeosporioides showed that there was damage to the structure of fungal hyphae in the treatment of SMS water extract with 100% extract concentration. SMS might offer an eco-friendly solution for enhancing agricultural productivity and promoting waste valorization in Indonesia.
