Abstract

There are 14805.14 ha of North Sulawesi coastal ecosystems  that has been damaged. Baringtonia asiatica Kurz (Keben) is one type of coastal plants that can be used to protect  coastal areas . Unfortunately, the propagation technique of Keben was not widely studied. This study aims to determine the characters of seedlings produced from the stumps of seed germination. The research used Complete Random Design with nine treatments, consisting of combination betwen three levels of  root length (0 cm, 5 cm and 10 cm), and three levels of the stems length (5 cm, 15 cm and 30 cm). Parameters for analysis include percent of success, growth and quality index. The results show that root length and stem length factors significantly affect the height and robustness value.  Treatment of root length of 10 cm and 5 cm rods allegedly produces the most excellent quality with the survival rates 93%, height 10.3 cm, diameter 1.08 cm, robustness value  2.03 and index of seed quality 1.35. Based on regulation of land rehabilitation, the height of 10 weeks stump have not qualified yet.

Abstract

Tangale Nature reserve is a conservation area located in Gorontalo that have the biodiversity typical of Wallacea bioregion including macroscopic fungi. The purpose of this study was to identify the fungal species diversity found in the Tangale Nature reserve as well as its potential use, considering that the information on species diversity of fungi in the Wallacea region is very limited. This research was conducted using the cruise method by identifying macroscopic fungi along the hiking trail of Tangale Nature Reserve. The macroscopic fungi were observed for its morphological characteristic include the colour, diameter, surface of the veil, the shape of the stem, the length and diameter of the stem, the lamella, including ring and pore, type of lamella and the type of volva. The research recorded the substrates and the location where the fungus was found. Data were analyzed descriptively qualitative. The results of the research identified 28 species of macroscopic fungi that included to the division Ascomycota and Basidiomycota. It belongs to 16 families and 8 orders  are Pezizales, Agaricales, Auriculariales, Boletales, Cantharellales, Gomphales, Polyporales, dan Russulales. Based on place to grow as much as 57,14% were found growing on decaying wood and 42,86% found growing in the soil/litter. Based on the potential of use, it has identified four species of mushrooms potentially as edible mushroom are Pleurotus ostreatus,  Auricularia auricula, Ramaria formosa, and Polyporus arcularius. 11 species of mushrooms potentially as medicinal mushroom are Calvatia craniiformis, Scleroderma citrinum, Lenzites betulina, Microporus flabelliformis, Coriolus versicolor, Microporus xanthopus, and Albatrellus confluens.
