Abstract

DEWI, A. P., ARIYANTI N. S. & WALUJO, E. B. 2016. Diversity of plants used for plaited crafts by the Dayak Iban-Désa in Kabupaten Sintang, Kalimantan Barat. Reinwardtia 15(2): 67 – 79. — Many plants are used for making plaited crafts such as basketry and woven mats by the Dayak Iban-Désa, a sub-tribe of the Dayak in Kalimantan Barat, Indonesia. The Dayak Iban-Désa gather the craft materials mostly from the plants in the forest. However, the habitats of these plants are being threatened by deforestation. The diversity of plants used for crafts is here documented. This study recorded the scientific names of plant species used for the craft plaiting, and observed abundance of plants used for craft. Information about the plants used were gathered using non-structural interview and focus group discussion (FGD) with the informants and participants. The abundance of plaited plants was observed in 46 plots of 10 × 10 m2 plots by participative ecological method. Nineteen plants species were used as plaited material, belonging to four families: Arecaceae, Poaceae, Pandanaceae and Zingiberaceae. Two species of rattan (Calamus sp. and Plectocomiopsis wrayi Becc.) have the highest Index Cultural Significance (ICS) value. Those species were considered as the most valuable plant materials because of the quality of fiber, intensity on harvesting, and the resulting quality of plaited craft products. However, the demand for high quality products is not always supported by the availability of plant materials in the forest. Therefore, the cultural significance of plants (the ICS values) and their availability should be considered when determining the conservation strategy for each of these species.

Abstract

Abstrak Pengenalan ciri makhluk hidup dalam praktik identifikasi sebagian besar menggunakan ciri morfologi. Ciri anatomi memperkuat ciri morfologi atau menyelesaikan permasalahan kerancuan identifikasi secara morfologi. Penelitian ini bertujuan untuk mengetahui karakter anatomi daun pada 11 spesies famili Phyllanthaceae yang ditemukan di wilayah eksplorasi Kabupaten Banggai Kepulauan. Metode yang digunakan adalah pembuatan preparat paradermal dan transversal helai dan tangkai daun. Karakter yang diamati pada setiap preparat adalah karakter paradermal yaitu epidermis dan derivatnya, karakter transversal meliputi bentuk dan jumlah lapisan epidermis, mesofil, keberadaan kristal dan karakter khusus spesies serta bentuk berkas pengangkut pada tulang daun dan tangkai daun. Berdasarkan preparat paradermal daun diperoleh tipe daun hipostomatik dengan tipe stomata umumnya parasitik dan anomositik, dan ditemukan variasi tipe stomata anisositik pada Baccaurea nanihua dan Antidesma excavatum. Pada preparat transversal diperoleh tipe daun dorsiventral, bentuk epidermis dan jaringan tiang yang beragam. Pada organ tangkai daun, ditemukan empat tipe berkas pengangkut, yaitu bentuk lonjong dengan dua tambahan berkas pengangkut, bentuk dasar menyerupai ginjal, bentuk semi-lunar, dan bentuk lonjong dengan satu berkas pengangkut. Abstract Morphological characters are commonly used as a tool for plant identification. Anatomical characters can also be used as additional characters to provide strong descriptions of morphological characters and to resolve unclear identification of morphological characters. This study aims to identify leaf anatomical characters of 11 species of Phyllanthaceae family collected from the Banggai Kepulauan Regency. The characters are observed in each slide were paradermal characters, namely epidermis and its derivatives; transverse characters including the shape and number of epidermal layers, mesophyll, presence of crystals and species-specific characters as well as the shape of the vascular bundle on the midrib and petiole. The observation on paradermal section of lamina showed that all species have hypostomatic leaf, parasitic and anomocytic stomata types with variation of the anisocytic types were found in Baccaurea nanihua and Antidesma excavatum.Observation of the transverse section showed dorsiventral leaf types, size variation of upper epidermal cells as well as variations of palisade cells. The observation on transverse section of the petiole showed four types of vascular bundles in the petiole: oval shape along with two small separated vascular, the kidney – like shape, the semi-lunar shape and oval single vascular bundle.

Abstract

Suku Asteraceae merupakan suku dengan jumlah jenis tertinggi dan perawakan bervariasi. Sebanyak ± 30.000 jenis tersebar di dunia dan 150 marga diantaranya tersebar di kawasan Malesia. Jenis-jenis Asteraceae di Pulau Jawa tercatat dalam buku Flora of Java Jilid 2. Namun, dalam beberapa tahun terakhir terdapat beberapa jenis yang belum tercatat dalam Flora of Java telah ditemukan di Jawa. Penelitian ini bertujuan untuk mengungkap jenis tumbuhan rekaman baru untuk melengkapi penyusunan buku Alien Flora of Java. Penelitian ini dilakukan dengan metode jelajah pada Maret 2019 hingga Agustus 2020 di beberapa lokasi di Pulau Jawa. Terdapat satu jenis tumbuhan rekaman baru dari suku Asteraceae yakni Centratherum punctatum di Desa Galonggor Bogor dan Jatinangor yang telah ditemukan tumbuh meliar dan belum tercatat sebelumnya dalam Flora of Java. Jenis ini menambah data anggota Centratherum yang terdapat di Jawa. Pendugaan asal, penyebab meliar, pemanfaatan, serta kandungan kimia jenis ini dipaparkan di dalam tulisan.
