Indonesia's coastal areas have a large area and potential for mangrove ecosystems. Of the approximately 15,900 million ha of mangrove forests in the world. 27% or 4,293 million ha are in Indonesia. The Sicanang Medan Belawan mangrove forest, North Sumatra Province, is a wetland area which mostly consists of mangrove forests. In the mangrove forest, there are Rhizophora apiculata and Avicennia alba species. Mangroves have unique morphological characters as a form of adaptation to the environment, one of which is the salinity of sea water which is the level of salinity or salt content in seawater. In the mangrove forest of Sicanang Medan Belawan, there are Rhizophora apiculata and Avicennia alba species which have the characteristics of vivivar culture development. From the results of test 1 on the species Rhizopora apiculata, it was found that the highest salinity level at the muddy and sandy station was 30 ppm, and the highest pH was at 7.79, and at a temperature of 29 C. While for Avicennia alba the highest salinity value was obtained at 30.6 ppm, the highest pH was at 7.82. , and temperature at 29.5 C. Based on the results that different zoning could affect yield, the vivivary shape of mangroves also had an effect on yield. salinity affects mangroves to develop, the higher the salinity, the more difficult it is for the seeds to develop

Exploration of Family Rutaceae in Garden Eden 100 Tobasa Agrowisata Forest Nurhasnah Manurung; Pandu Prabowo Warsodirejo

Research in the Eden 100 agrotourism forest located in the area of Lumban Rang, Sionggang Utara Village, LumbanJulu District, Kab. Toba Samosir North Sumatra has been carried out for 3 months using "Survey or Exploration Method". The aim of this research is to find out data on plant species of family Rutaceae in the Eden Park area 100 and then make herbs and to produce learning devices in the form of dabbing as ingredients teach Biology courses in High Plant Taxonomy. The results showed that there were 9 types of plant family Rutaceae with the Genus Citrus as many as (6), Genus Zanthoxylum (1), Genus Triphasia (1), Genus Aegle (1), so the most dominant is the Genus Citrus. such as Lime (Citrus aurantifolia), Andaliman (Zanthoxylumachanthopodium), Orange Purut (Citrus hystrix DC), Tiger Orange (Citrus medica), Kingtit Orange (Triphasiatrifolia), Lemon Orange (Citrus lemon), Kasturi Orange (Citrus madurensis) , Sweet / Squeezed Oranges (Citrus sinensis), AegleMajamarmelos (L.) Corr. The Rutaceae family plant found in the Eden 100 agrotourism forest is still relatively small when compared with the total total genus Rutaceae 150 genera and 1500 species

Abundance Study of Koompassia excelsa in Maintaining Conservation of Ecosystems in Tangkahan Langkat Nature Reserve, North Sumatra Pandu Prabowo Warsodirejo; Asri Safitri Hasibuan; Arifin Ritonga; Lia Listiana

Writing this paper aims to introduce the king's wooden tree (Koompassia excelsa) to the general public, as the background of this writing because North Sumatra especially in the Tangkahan Langkat forest has one tree with a height of almost 88 meters with very large roots and very hard wood, but not much people know it, this can happen because of lack of exposure and lack of publicity both directly and with the mass media. The method used in this study is the Exploration Method and directly record the sample during the trip. The area observed in the data collection process is 40 hectares divided into 2 regions, namely Region A (15 Hectares) and Region B (25 Hectares). The purpose of this study is to explain that the Koompasia excelsa species is an original species called Timber The king and saw its abundance in the Gunung Leuser Tangkahan Langkat Forest which is adjacent to the Natural Protection Forest of Bukit Barisan National Park in North Sumatra. Based on the results of research in the Gunung Leuser National Park Forest area, North Sumatra it can be concluded that the tualang tree can be found in lowland habitats with altitudes reaching 350 m above sea level and slope rates varying from 40-60. The dominance of species and associations is one of the factors that influence the adventure habitat, but that does not mean that other species do not influence the adventure habitat, such as altitude, soil type, and species of animals that have not been observed and analyzed further. In addition, it is necessary o carry out an inventory of adventurers to estimate the population in North Sumtatra, so that if there is a decline in population, conservation status can be improved.
