ABSTRACTCempaka wasian (Magnolia tsiampaca (Miq) Dandy) is a forest tree species that has recalcitrant seed character. Recalcitrant seeds are difficult to be stored for a long period, thus storing the seedlings can be considered as an option. This research aims to determine the effect of growth inhibitors and planting media on seedling growth during storage. The inhibitors used were paclobutrazol 250 ppm, NaCl 0,5% and aquadest (as control treatment). The media used consisted of top soil+cocopeat (1:1), top soil+sand(1:1) and top soil+husk charcoal (1:1). The research design used was a complete randomized factorial pattern design. The results showed that the inhibitors had a significant effect on the growth os seedling height. Provision of 250 ppm paclobutrazol was able to inhibit the growth of seedling height. Planting media also had a significant effect on the growth of height and diameter of the seedlings, also on seed quality index of cempaka wasian. The soil+cocopeat and soil+sand planting media are effective to reduce the growth rate in both height and diameter of cempaka wasian seedlings during storage. Key words: Cempaka, growth inhibitors, planting media, seedling ABSTRAKCempaka wasian (Magnolia tsiampaca (Miq) Dandy) adalah salah satu jenis pohon hutan yang memiliki karakter benih rekalsitran yang sulit disimpan dalam jangka waktu lama, sehingga perlu dilakukan penyimpanan dalam bentuk semai dengan menggunakan bahan semai.

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

Implementation of community empowerment scheme in the Poigar Production Forest Management Unit (PFMU) Model area needs to take into account on community perception and behavior. This study aimed to determine the level of perception and behavior of the community towards the existence Poigar PFMU Model and to recommend the appropriate community empowerment scheme. To find out the perceptios and behavior of the Lolan Village community towards Poigar PFMU Model was by using Likert Scale. Furthermore, to determine the factors that influence people's behavior, then Spearman rank (Rs) correlation test was used. The results showed that the level of perception of Lolan village communities to the existence of the Poigar PFMU Model was in good category, while the society behavior was in the less category. A good public perception of the Poigar PFMU Model area, did not have significant influence on its behavior. Community social characteristics that correlate with the behavior of the community were among others: education, level of income sourced from outside the area and level of interaction with the forest. Based on this, community empowerment strategy that is most likely to do in Poigar PFMU Model is through the Forestry Partnership Scheme.
