Abstract. Agustini V, Zebua L, Wenda N. 2016. Inventory of native orchids in Makki Sub-District, Lanny Jaya, Papua, Indonesia. Biodiversitas 17: 301-305 . The establishment of this new district gives impact to the plant habitat including orchids. The study was done in Makki Sub-District, Lanny Jaya, Papua, Indonesia. The present study is an inventory orchid species in Lanny Jaya by explorative method. There were 22 species (17 genera) consist of epiphytic, terrestrial and lithophytic orchids. Among them Dendrobium subclausum is the most abundance species in this area. With the combination of bright orange and yellow colors in sepal it can be seen throughout the year.
Pandanus is one of the unique plants, especially for Austronesia and Melanesia society in tropical areas, including Papua. The one of Pandanus which often exploited by local people in the middle mountain of Papua called coconut pandan (Pandanus juilianettii Martelli). The aim of this study is to determine the utilization of coconut pandan by Lanny Jaya tribes in the middle mountain of Papua by using qualitative approaches (observation and interview). Purposive and snowball sampling has been used for informant selection. The results showed that all the plant organs (leaves, stem, roots, and fruits) could be utilized. For instance, the stem organs are used as materials for house building such floor and walls, and it also can be used as firewood. The people of this tribe also utilized the leaves as traditional mats and umbrella, and the leaves from Woromo cultivars can be used as cigarette rolls. The root fiber is used as material for making a traditional bag (noken) and to make the arrow. People of this tribe also consumed the fruits of coconut pandan because it tastes like coconut fruits.
Abstract. Zebua LI, Gunaedi T, Budi IM, Lunga N. 2019. The DNA barcode of red fruit pandan (Pandanaceae) cultivar from Wamena, Papua Province, Indonesia based on matK gene. Biodiversitas 20: 3405-3412. The red fruit pandan has been used by the people of Wamena in central highlands of Papua as medicinal plants, food ingredients, and religious ceremonies. Based on morphological characters, there are 39 cultivars of red fruit pandan in New Guinea. A standard method for plant species identification through DNA barcodes has been recommended to use matK gene. The research aimed to determine similarities in DNA barcode sequences of six red fruit pandan cultivars with its close relative that listed in NCBI system and to recommend the reliable DNA barcode for identification of this cultivar. Polymerase Chain Reaction was employed DNA to amplify matK gene fragments using an available forward primer (5’CGA TCT ATT CAT TCA ATA TTT C 3’) and reverse primer (5’TCT AGC ACA CGA AAGTCG AAG T 3’). The software BLAST, Bioedit, and ClustalX were used to analyze the data. Barcode DNA of red fruit pandan showed 1474 bp nucleotides sequence based on matK gene. An indication of six red fruit pandan cultivars showed that high similarity 99% with Pandanus conoideus Lam. It can be concluded that matK gene can be used to determine the species level in Pandanus.
Study on traditional knowledge of Papua communities for recognizing, classifying, and utilizing the Red fruit Pandanus cultivar (Pandanusconoideus Lam.) have been carried out in four Papua regions (Arfak-Manokwari mountain, Serui, Cyclops-Jayapura mountain, and Jayawijaya District). Sampling method of research was interview and observation methods. Informans were selected using purposive sampling and snowball sampling techniques. The data were analyzed on descriptive bases. The result showed that Papua communities have different knowledge of recognizing and managing the red fruit pandan. Characteristics used to distinguish cultivars were fruit size, seed size, and fruit colors. Based on ethno-biological data, there were two classification patterns of the red fruit in Papua. The first pattern were kingdom, life form, and specific structures. The second pattern were kingdom, life form, generic, and specific structures. The second pattern was similar to the botanical nomenclature. Utilization of the red fruit pandanwere morediverse in Papua communities living in mountainous than oher places, due to three important functions three functions, namely social, health, and economic functions. Utilization of the red fruit in Papua communities living in the bay areas were less varied, because the red fruit pandanwas only utilized as a food supplement. Generally, Papua communities living in the bay consumed the red fruit without being processed first.Key words: Classification, nomenclature, knowledgement, recognize, utilization.
Increasing population may result in excessive changes of land use and natural resource utilization. Local communities of mangrove forest areas have been dependent heavily on forest conditions to survive. Conversion of forest to development requirements is apparently to affect the structure and income of local communities who live traditionally in the region. The purpose of the study is to understand the structure of mangrove forest vegetation and changes of people's income depending their live on mangrove forests in the Bay of Youtefa, Jayapura. Sampling method was purposive sampling of respondents and mangrove vegetation analysis was conducted using line transect method. The plot size were 10 x 10 m2; 5 x 5 m2; and 2 x 2 m2 used for viewing the ecological importance valua index (IVI) of tree, stake and seedling. The results showed that there were 10 known species of mangrove dominated by Rhizophora apiculata, R. mucronata and R. stylosa respectively. R. mucronata dominated the area and has the highest importance value index (IVI) level. Development structure including means of transportation (flying bridge) have a major impact on the local community Increasing economic losses. There is a decrease of direct income of communities as much as 2.05 billion per year (from 5.65 billion to 3.61 billion per year).Key words: mangrove ecosystem, vegetation structure, economic value, Jayapura.
