Abstract

The comprehensive revision of the genus has been done in the Malay Peninsula, New Guinea, Sumatra andKalimantan. In Java, the revision of Licuala has never been recently completed. This study was based onmorphological characters of specimens which are preserved in Herbarium Bogoriense. The several living collectionscultivated in Bogor Botanical Garden were studied. The aim of this study is to ascertain the correct names andimprove the species delimitation of Licuala in Java. The result shows that there are three species of Licuala inJava. They are L. gracilis, L. pumila and L. spinosa. Two previously known species have been placed into synonymies;L. flabellum to L. gracilis, and L. spectabilis to L. spinosa. Licuala gracilis is endemic for west Java.

Abstract

Information on the diversity of understorey plants in Siranggas Wildlife Sanctuary is still limited. This research was carried out to determine the diversity of understory at the Siranggas Wildlife Sanctuary Area, Pakpak Bharat Regency, North Sumatra. The study was conducted using purposive sampling method, with 5 sampling sites. Twenty plots measuring 2m x 2m were placed at each site to obtain a total 100 plots. The result showed that there were 41 species of understory plants found in the Siranggas Wildlife reserve, consisting of two division namely Pteridophytes (10 species) and Spermatophytes (31 species). The highest Important Value Index (IVI) value of understory plants in the study was obtained for Selaginella intermedia at 28,6%. The diversity index of all understory plants in the study was categorized as moderate level at value 2,88. The understory plants uniformity index was relatively high at 0,77. The species of understory plants in the study area must be preserved to maintain their sustainability.

Abstract

ARTICLE HIGLIGHTS- The survey method was successful in identifying the species Marchantia and mapping their distribution in North Sumatra- Eight taxa of Marchantia confirmed in North Sumatra, M. emarginata subsp. cuneiloba has the most widely distributed species. - Species distribution linked to environmental factors like elevation, humidity, rainfall, soil types, slope, solar intensity, and types of land coverABSTRACTMarchantia is one of the large genus complex thalloid liverworts (Marchantiophyta). The species of Marchantia has a wide distribution throughout the world, and occupies a variety of substrates. Studies on the presence and distribution of Marchantia species are still limited in North Sumatra. Therefore, the research was carried out to inventory the species of Marchantia and map their distribution in North Sumatra. Survey method was used to inventory the species of Marchantia, covering 9 locations, namely: Aek Nauli Forest, Bukit Barisan National Forest Park, Bukit Lawang, Resort Cinta Raja, Dolok Tinggi Raja Nature Reserve, Sibayak Mountain, Sicike-cike Natural Park, Silima-lima waterfall, and Taman Eden 100 Natural Park.  Geographic Information System (GIS) was used to map the distribution of the species. The results showed that there were eight taxa of Marchantia confirmed in North Sumatra, namely, M. acaulis, M. emarginata subsp. emarginata, M. emarginata subsp. cuneiloba, M. geminata, M. paleacea subsp. paleacea, M. polymorpha, M. treubii, and Marchantia sp. The most widely distributed species of Marchantia is M. emarginata subsp. cuneiloba, found in 7 study locations. Species with the least distribution are M. treubii and Marchantia sp., each species found only in one location. Marchantia spp. in North Sumatra spread at an altitude of 77 to 1976 m alt, occupying habitats with 6 types of soil (orthic acrisol, humic andosol, humic acrisol, and humic cambisol), with rainfall of 1800-3600 mm/year. Marchantia species are found on sloping plains to steep, in various habitat, namely secondary forest, primary and secondary forest borders, dryland farming, primary and plantation borders, and plantations. The results of this study are important for the conservation of Marchantia spp. in North Sumatra considering the many benefits of the species.

Abstract

The cultivation of Kelulut (Trigona) honey bees has been initiated by the Peduli Pesisir Farmers Group (Mitra) in a mangrove-based agro-tourism area in Beras Basah Village, Pangkalan Susu District, North Sumatra. However, due to limitations in mastering the science and technology (IPTEKS) of kelulut cultivation and the number of stock owned by partners as well as several other aspects, partners have not been able to meet consumer demand, based on Focus Group Discussions (FGD) and community service team discussions with several group members. from informal farming and document searches, it can be seen that the partner has the right to manage an area of 4 hectares and it has great potential to increase the honey production of kelulut bees, because in this area there are various plants that produce flowers as a source of nectar/main food for kelulut bees. Based on some of the information above, a problem analysis was carried out by the community service team involving partners, so that an agreement was born to carry out several activities that could support the smooth transfer of science and technology, such as; counseling, discussions, training and the addition of a number of stup (kelulut bees + media).
