Abstract

Stingless bees forage to the flower for nectar and at the same time, pollen also trapped in the body hairs of the bees. Mostly pollen was concentrated into the pollen basket and transferred to the pollen and honey pot in the stingless bee nest. Pollen is male gametophytes of seed plants which have various of shapes, sizes, and ornamentations. This palynology study was aimed to identify the plants of pollen source that were found in honey of stingless bee Heterotrigona itama and Tetragonula laeviceps in Belitung and to analyze characteristics of the pollen. Pollen was extracted from honey and conducted the acetolysis and identification of the pollen in honey. We found 11 and 19 plant species as pollen soirce in the honey of H. itama and T. laeviceps, respectively. Pollen from Macaranga tanarius (23.72%) and Cocos nucifera (22.53%) were the two most dominant species on the H. itama honey. Pollen from Ageratum conyzoides (16.36%) are most often found in T. laeviceps honey. The most common pollen in honey of H. itama and T. laeviceps were from Arecaceae with a total of three species. Pollen from plants with tree habitus is most commonly found in honey of both species of stingless bees.

Abstract

Epiphytic ferns can be found in host trees from the Angiosperm and Gymnosperm groups. Epiphytic ferns in Angiosperm plants host have been widely studied, but there is little known for Gymnosperm plants host. The aim of this study was to identify the species of epiphytic ferns in the Gymnosperm plants host at Cibodas Botanical Garden and to analyze the diversity of epiphytic ferns based on microclimate conditions and the surface texture of Gymnosperms plants host. Epiphytic ferns diversity data was obtained using purposive random sampling method. Factors that influence the occupancy of ferns are analyzed using Principal Component Analysis. Epiphytic ferns in Gymnosperm host at Cibodas Botanical Garden were identified as 18 species including 7 family. The most dominant species of epiphytic fern is Davallia denticulata (59.45%). Diversity of epiphytic fern on Gymnosperm at Cibodas Botanical Garden is moderate (H’ = 1.81).

Abstract

Sweet star fruit (Averrhoa carambola L., belimbing manis) is one of Indonesia’s most popular fruit plants. Anatomically, the characters of the local sweet star fruit of Mekar Sari Fruit Garden are not widely known, so this study aims to observe the anatomical structure of the leaves. The materials used were star fruit leaves of varieties Demak Jingga, Demak Kapur, Demak Kunir, Welahan, and Wulan. The leaves of star fruit varieties were made microscopic preparations in paradermal incisions using the whole mount method and transverse incisions using the paraffin method. The observation result of the paradermal incision of sweet star fruit leaves showed that the type of epidermal cell wall is straight and shallow grooved. The leaf stomata of five sweet star fruit varieties were paracytic. The calculation of the index value, size and density of stomata varied between varieties. The highest stomata density and index were found in the Welahan variety. The results of the transverse incision of sweet starfruit leaves showed that the five local sweet star fruit varieties have mesophyll tissue of the dorsiventral type. Wulan variety has leaves and mesophyll tissue which tends to be thicker than other varieties.

Abstract

The use of medicinal plants to treat disease is still used in many areas. This research aimed to provide information about medicinal plants in Sumber Sehat Multifarm. Data such as local name, scientific name, habitus, part of the plants that are used, benefits, how to use, and also plant processing were collected through a semi-structured interview method. Data analysis was done through a quantitative method which calculated calculating the percentage of parts of the plants that were used and the habitus of the plants that were found. Qualitative analysis of data was done descriptively. The result showed that Sumber Sehat Multifarm uses 177 species belonging to 64 families as medicinal plants. Most plant species have herbaceous habitus. Part of the plants that are used mostly are the leaves. Most plant species of plant can treat more than one kind of disease. The benefits of the plant can be grouped into two categories: plants used to cure internal organ disease and plants used to treat external organ disease. Most plant species can be consumed by brewing or freshly eaten.

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.
