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.

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.
