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. Tujuan penelitian ini adalah untuk mengetahui pengaruh bahan penghambat pertumbuhan dan media tanam terhadap pertumbuhan semai cempaka wasian selama masa penyimpanan. Bahan penghambat pertumbuhan yang digunakan adalah paklobutrazol 250 ppm, NaCl 0,5%, dan akuades sebagai kontrol. Media tanam terdiri dari tanah+cocopeat (1:1), tanah+pasir (1:1), dan tanah+arang sekam (1:1). Rancangan percobaan yang digunakan adalah rancangan acak lengkap pola faktorial. Hasil penelitian menunjukkan faktor zat penghambat tumbuh memberikan pengaruh yang nyata terhadap pertumbuhan tinggi bibit. Pemberian paklubutrazol 250 ppm mampu menghambat pertumbuhan tinggi bibit. Faktor media tanam memberikan pengaruh nyata terhadap pertumbuhan tinggi, diameter, dan indeks mutu bibit cempaka wasian. Media tanam tanah+sabut kelapa dan tanah+pasir merupakan media yang efektif mengurangi kecepatan pertumbuhan tinggi dan diameter semai cempaka wasian selama penyimpanan.Kata kunci: Cempaka, bahan penghambat pertumbuhan, media tanam, semai

Langusei (Ficus minahassae (Teysm.et.Vr.) Miq) is one of the endemic flora of Sulawesi which existence is increasingly threatened. Attempts to maintain the existence of Ficus minahassae species by understanding the cultivation techniques of the langusei species, especially regarding the appropriate germination techniques, need to be addressed. This study aims to determine the level of fruit maturity and the appropriate extraction treatment for the germination of langusei seeds. The experimental design used in this study was a complete randomization design which is arranged in a factorial pattern. The first factor is the classification of the level of seed maturity based on fruit color categories: 1) Orange-brown fruit, 2) Orange-reddish fruit, 3) Red fruit, and 4) Red-black fruit, while the second factor is the fruit extraction treatment which consists of: 1) Extraction with dry wind treatment for 24 hours, 2) Extraction with drying treatment for 12 hours, and 3) Extraction with water treatment for 24 hours. The results showed that the fruit maturity level and the appropriate extraction treatment to produce optimal langusei seed germination were in the orange-brown and orange-reddish fruit (mature fruits prior to ripening) which was soaked in water for 24 hours.

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.
