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

Technical rehabilitation planning of BPDAS Tondano on coastal area has reached 10,000 hectares, thus require many seedlings. Nyamplung has potential as rehabilitation plant in coastal at the same time it can support national demand of biofuel. However the nurseries of nyamplung in North Sulawesi are not optimal and need appropriate information of weaning method. This research used completely randomized design with three treatment factors, namely 1) Cutting the leaves consist of two levels ie D1 (pair leaves) and D2 (intact leaf); 2) Cutting intact seeds, consists of two levels i.e B1 (removed seed) and B2 (intact seeds); and 3) Cutting the roots lenght consist of three levels i.e A1 (5 cm), A2 (10 cm) and A3 (15 cm). There were 180 seedlings taken from seed that germinated using cocopeat media. Results of variance analysis showed that the applied treatment only affect the heigth growth. The survival rate is not affected by all treatments or in the other words survival rate reached 100 %. The treatments on leaves and seeds gave significant effect, on the contrary with root treatment. The treatment of intact leaf (D2) and intact seeds (B2) produced the best height growth responses i.e 4.60 cm and 4.63 cm. Keywords: Calophyllum inophyllum, survival rate, weaning technique, height

Abstract

Fungi have a vital role in ecological processes, as an indicator of health of an ecosystem, it is not only has the potency for medicine and food but also variety of unexplored potential. Arboretum has high potential for biological conservation including fungi species, so information on its diversity and potency are very important for the basis of its management. The purpose of this research was to explore the diversity of species and the potential of macroscopic fungi in the BP2LHK Manado Arboretum. Observations were conducted 8 times in May, June, and September 2016 using a cruise and an opportunistic method. The infromation of growth media, light intensity, and temperature were collected as a supporting data. The result showed that arboretum stored 48 species of macroscopic fungi with different characteristics. 39 species were identified, divided into 2 divisions, 6 classes, 9 orders, and 17 families, while the remaining 9 species were unidentified.. The results showed that the diversity of macroscopic species habitat were dominated by 31 species grown on necromass, 11 species grown on litter and 6 species grown on soil. Based on its potential, there were 2 species of toxic fungi, 1 species of edible and medicinal fungus, 2 species of edible fungi, 5 species with medicinal fungi, 19 species were not edible, and 19 species with unknown benefits.Keyword: arboretum, diversity, macroscopic fungi, Manado

Abstract

This study aimed to know the dynamic of survival rate and growth of Rhizophora mucronata Lamk which planted by using propagules at Alo Beach, Karakelang Island, Talaud. The study was conducted from June 2013 to April 2017, used a complete randomized design with 6 treatments i.e. K1, K2, K3, K4, K5, K6. The amount of propagules in every treatment were 100 pieces each. The parameter observed were characteristic of substrat, survival rate,height and diameter of the plant’s in age of 1.5 months and 48 months. The results showed that treatment had a significant effect on survival rate and growth of Rhizophora mucronata plants. The rehabilitation was categorized as success at 1.5 months old, but it was failed inthe 48 months. Beside waves and tides, low substrat nutrition became the main factor that affect the success of mangrove rehabilitation in Alo Beach.The K5 treatment has the highest survival and growth rate of the plant. The K5 treatment using pnematophore as brace, while planting without brace/K1 has lowest survival and growth rate since months old.Keywords: mangroves, rehabilitation, Rhizophora mucronata, Talaud
