Abstract

The existence of insects is very abundant and has an important role in the ecosystem. In addition to a very important function in the ecosystem, ants are used as bioindicators in changing the habitat of an area and seeing changes occur in the environment. Ants are commonly found in a variety of habitats, in addition to terrestrial areas ants are found in coastal areas because there are habitats that allow the presence of ants in the form of mangrove vegetation and ecologically, ant nests are scattered from mangrove forests and trees on the coast. This research was conducted on 10 February - 10 March 2016 in the TWA area of Pantai Panjang, Pulau Baai Bengkulu. Use the roaming or xploration method. Each location point to set a trap (pitfall). When installing pitfalls (pitfall) is done at 09.00-11.00 and 14.00-15.00 WIB, by installing ten trap traps (pitfall) for three days. From the results in the field found 10 types of ants from the Order Hymenoptera Family Formicidae. 8 species constitute members of the Subfamily Formicinae including; A.gracilipes, P. longicornis, C. carnelius, Oecophylla sp, P. carbonaria, C. rufipes, Camponotus sp, P. jerdon, two other members of the Dolichoderinae Subfamily; T. melanocephalum, D. thoracicus.

Abstract

Pacar air (Impatiens balsamina L.) plant belongs to the Balsaminaceae family and is used as an indigenous medicine in Asia for fingernail inflammation, fractures, and rheumatism treatments. Moreover, the antipruritic, antianaphylactic, antifungal, antibacterial, and antitumor activities of some compounds, especially phenolics and quinones from this plant have been studied extensively. Therefore, this study aims to determine the antifungal activity of Pacar air leaves (Impatiens balsamina L.) methanol extract against Rhizopus oryzae L. and the IC50 value. The results showed that an increase in the concentrations of I. balsamina L. leaves methanol extract significantly raised the fungal growth. Furthermore, the extract inhibition against R. oryzae L. at various concentrations of 0.5; 0.7; 0.9; 1.1; and 1.3% w/v were 10, 21.9, 58.06, 68.06, and 79.72%, respectively, while the IC50 value was 0.896%. Hence, the presence of naphthoquinones and other secondary metabolites are responsible for its antifungal activity. Based on these results, the antifungal potential of I. balsamina L. leaves against soft-rot fungi is useful in the future.

Abstract

Perspektif saintifik, yaitu pendekatan menggunakan langkah-langkan serta kaidah ilmiah dalam proses pembelajaran. Sumber ilmu dan informasi bisa ditemukan dimana saja terutama di alam, berbagai sumber ilmu dan kreativitas pada tumbuhan dapat dijadikan prepektif saintifik bagi siswa. Tumbuhan memiliki teknik pengelolaan awetan sebgai sumber belajar serta kreativitas bagi siswa. Banyaknya tumbuhan berbunga di sekitar perkarangan menjadi potensi dalam membuat pemanfaatan produk kreatif dengan menggunakan awetan tumbuhan. Diharapkan dengan adanya pelatihan pemanfaatan tanaman perkarangan, hias dan budidaya menjadi produk kreatif bernilai seni dan ekonomis dapat meningkatkan keterampilan siswa dan peserta didik sebagai upaya alternatif peningkatan pendapatan. Tujuan pengabdian kegiatan pemanfaatan tumbuhan sekitar sekolah dalam pembuatan awetan tumbuhan untuk media kreativitas tumbuhan (botani). Kegiatan ini dapat diaplikasikan sebagai media pada materi keanekaragaman tumbuhan dan dimanfaatkan sebagai kegiatan wirausaha berbasis biologi.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui kecepatan pengeringan dalam proses pembuatan herbarium dengan menggunakan tiga jenis sasak : sasak berbahan kayu, sasak berbahan besi plat dan sasak berbahan besi bulat batangan. Penelitian ini merupakan jenis penelitian eksperimental yang dilakukan dengan mengeringkan spesimen tanaman sirih pada suhu 50oC dengan waktu pengeringan 3x24 jam. Alat pengering yang digunakan adalah oven. Untuk mengetahui kestabilan pengoperasian oven digunakan stop kontak timer. Untuk mengetahui kadar air tanaman sirih digunakan neraca analitik. Hasilnya adalah jenis sasak terhadap kecepatan pengeringan terbaik menurut urutan adalah : 1) sasak besi bulat batangan, 2) sasak kayu, 3) sasak besi plat. Sedangkan jenis sasak terhadap kualitas spesimen terbaik menurut urutan adalah : 1)  sasak kayu, 2) sasak besi bulat batangan, 3) sasak plat besi.

Abstract

Sorus is a collection of complex sporangiums in which there are spores. Found on the upper (Addaksial) and lower (Abaksial) surfaces of the leaves of spike plants (Pteridophyta). This activity aims to identify the location and shape of the sorus on the nails in the Bengkulu University area. Sampling using purposive sampling methods. The identification results found differences in the location and shape of the sorus from the spike plant (Pterydophytha) in the Bengkulu University area. There are 9 families of spike plants (Pterydophytha) identified, namely Lygodiaceae, Gleicheniaceae, Dryopteridaceae, Cyatheaceae, Pteridaceae, Lomariopsidaceae, Osmundiaceae, Aspleniaceae, Polypodiaceae. The location of the spike plant sorus is at the end of the stem between the leaf bones, the veins of the leaf, near the edge of the leaf and on the edge of the leaf. The shape of the sorus of the spike plant (Pterydophytha) there are three, namely round, elongated and.

Abstract

Mangroves play an important ecological and economic role. TWA Pantai Panjang and Pulau Baai, specifically in Sumber Jaya Village, are directly adjacent to a river environment where seawater can enter during high tide. This seawater influence can affect the salinity of the waters, leading to varied responses from mangroves due to their differing tolerance ranges. The research aimed to identify mangrove species based on salinity conditions in Sumber Jaya Village, Kampung Melayu District, TWA Pantai Panjang, and Pulau Baai, Bengkulu Province. The research method used was descriptive explorative, with data collection at 3 stations using the Line Transect Plot method. The identification yielded 16 mangrove species from 9 families. Specifically, the Rhizophoraceae family included Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa, Bruguiera gymnorrhiza, and Bruguiera sexangular. The Avicenniaceae family was represented by Avicennia marina and Avicennia lanata. Other families included Combretaceae (Lumnitzera littorea and Terminalia catappa), Sonneratiaceae (Sonneratia alba and Sonneratia caseolaris), Acanthaceae (Acanthus ilicifolius), Asclepiadaceae (Calotropis gigantea), Apocynaceae (Cerbera manghas), Leguminosae (Derris trifoliata), and Malvaceae (Hibiscus tilaceus). The Rhizophoraceae family had the most species. Rhizophora apiculata, Rhizophora mucronata, and Rhizophora stylosa were found in a salinity range of 0 - 25 ‰, corresponding to freshwater to estuarine salinity types. Bruguiera gymnorrhiza and Bruguiera sexangula were found at salinities of 8-25 ‰, Avicennia marina and Avicennia lanata at salinities of 21-25 ‰, and Lumnitzera littorea at a salinity of 3 ‰.
