Abstract

Besiq Bermai Forest is part of Kalimantan forests known for vast plant diversity. The present study aimed to investigate flora diversity, composition, and ecology in Besiq Bermai Forest to support the management of biodiversity and forest conservation. Thirteen plots were established with different sizes of plots (100 m x 20 m plots for trees; 40 m x 5 m plots for saplings; and 5 m x 5 m plots for understory). Data recorded included plant species name and individual number of each plant species. Data analysed were Shannon-Wiener diversity index, Relative Density, Relative Frequency, Relative Dominance and Important Value Index. The principal component analysis (PCA) was performed to determine relationship between edaphic components and flora occurrence. The results showed that there were 93 species of trees (belonging to 48 genera and 22 families), 112 species of saplings (belonging to 62 genera and 43 families), and 48 species of understory (belonging to 28 genera and 20 families). Shannon-Wiener diversity index (H’) were 6.05, 6.25 and 3.26 for tree, saplings and understory, respectively. The most common family for tree and saplings in the forest ecosystem in this area was Dipterocarpaceae (Shorea spp). Species of tree with the highest importance value index were Dillenia excelsa, Syzygium sp. and Shorea parvifolia. The highest importance value index for species of saplings were Macaranga triloba and Shorea parvifolia; and for species of understory were Phrynium jagorianum. Ecological (edaphic) factors affecting the occurence and establishment of flora in Bermai forest were total N and C/N ratio. The present study has implication for the management of biodiversity and forest conservation.

Abstract

Information on the type of appropriate growing media for plant species in Zingiberaceae family has not been widely provided. This study aimed to examine the effect of several types of growing media on the growth of Hedychium borneense, an endemic and semi-epiphytic Zingiberaceae from Kalimantan. The study was conducted in a completely randomized design and the data has been analyzed using anova 1 way test. The results showed that the type of growing media gave a significant effect on plant height and number of shoots (tillers), but did not affect the number of leaves. The best growing media for the highest plant height average were sphagnum moss and sand + compost. These two types media, sphagnum moss and sand + compost, also give more shoots significantly compared to the other media. The highest life percentage is showed by the sphagnum moss media with 100% rate of life. Therefore, sphagnum moss and mixing media between sand + compost (1: 1) are the best growing media for semi-epiphytic H. borneense plants. Keywords: Epifit, Media Tanam, Hedychium borneense, Zingiberaceae.

Abstract

Jenis tumbuhan di sekitar aliran mata air  di kawasan hutan Pulau Moyo berperan dalam menjaga kestabilan aliran mata air. Keberadaan tumbuhan tersebut turut berperan dalam menjaga ketersediaan air di kawasan tersebut. Aliran mata air dikawasan hutan dalam musim kemarau  tetap ada dan aliran tersebut masuk dalam kawasan masyarakat. Warga memanfaatkan ketersediaaan air tersebut untuk kebutuhan sehari-hari. Penelitian ini bertujuan untuk mengatahui jenis-jenis tumbuhan di sekitar aliran mata air di kawasan hutan Pulau Moyo. Penelitian dilakukan dengan cara metode jelajah dengan mendata setiap jenis tumbuhan yang terdapat di tepi aliran mata air tersebut. Hasil penelitian menunjukan bahwa tercatat setidaknya ada 32 jenis pohon yang berada di kawasan aliran mata air dan rata rata berhabitus pohon besar. Jenis yang sering ditemukan adalah marga Ficus dan keluarga Moraceae. Secara keseluruhan kondisi aliran mata air di kawasan hutan tersebut adalah jernih.    Kata Kunci: Mata Air, Pulau Moyo, Diversitas
