Pertumbuhan Riap Diameter Pohon Bakau Kurap (Rhizophora Mucronata) Di Lampung Mangrove Center
Get PDFBakau kurap (R. mucronata) is a true mangrove. The height of this mangrove could reach 27 m and rarely exceed 30 m. The diameter trunk of this mangrove could reach 70 cm. R. mucronata stands was found in Lampung Mangrove Center (LMC), it was located in Margasari Village district Labuhan Maringgai, East Lampung Regency. The purposes of this study were to determine the diameter increment, growth models and stand growth past of R. mucronata at LMC. The research was conducted on July to August 2015. The method used measurement of diameter time series for three years (2013, 2014, and 2015) on circle form permanent plots with a radius 7 m of length are divided into three thinning blocks (A, B, and C). Block C was the control block or block that was not thinned and large thinning in blocks A and B, respectively 54.5% and 41.7%. The results indicated that the biggest diameter increment of three block at the age of 22nd years = 0.467 cm year-1. The estimation model of stand diameter (D) and diameter increment (MAI-d) based on the age of stand (X) could be formulated as follows: 1) Blok A D = 8,996 X0,021; MAI-d = 0,451 X0,035, 2) Blok B D = 8,215 X0,124; MAI-d = 0,412 X0,039, 3) Blok C D = 7,159 X0,074; MAI-d = 0,359 X(-0,012). Forecasting growth stands diameter R. mucronata age of 32nd years on the blocks A, B and C in a row were 10,280cm, 9,463cm, and 7,796cm while the diameter increment were 0,467cm, 0,430cm, and 0,354cm.

Pengaruh Zat Alelopati Dari Alang-Alang Terhadap Pertumbuhan Semai Tiga Spesies Akasia
Get PDFAllelopathy is the compound released by the plants (example: blady grass) to the environtment and where another plants is living and could obstruct or extinguish to another plants. The purpose of research were to figure out the effect of allelopathy from the blady grass toward the species of acacia seedlings, to figure out the weakest affected seedling species by blady grass allelopathy, and to figure out interaction between concentration of extracted blady grass and seedling tree species. The research was designed based on factorial in a complete random design. Factor I was the seedlings, consisted of acacia, mangium, and acacia alba, while factor II was concentration of extracted blady grass allelopathy, consisted of non extracted allelopathy, extracted allelopathy 25%, extracted allelopathy 50%, extracted allelopathy 75%, and extracted allelopathy 100%. Every treatment was repeated 5 times. The number of the seedlings for each experimental unit was two seeding. The observed variables were height, diameter of the stem, number of leaves, and living percentage of the seedlings. This observation data was tested by Bartlett test to find the variance homogenity. Then it was analyzed by using variance analysis, and tested by least significant difference (LSD). The calculation were done at 5% significant level. The result of this research showed that allelopathy of blady grass were significan to the growth of acacia, mangium and acacia alba seedlings. Based on the LSD at 5% was known that the concentrate of blady grass allelopathy had strongest negative effect to the growth seedlings was 100%. Seedling that was the most resistant to the allelopathy of blady grass is mangium seedling. It was known from the analysis of variance test there was an interaction between the seedling and the concentration of blady grass allelopathy that effect the height, leaves number, living percentage ofseedlings. Key words : allelopathy, blady grass, and acaci
Uji Daya Simpan Benih Jengkol (Pithecellobium Lobatum) Dengan Menggunakan Beberapa Media Simpan
Get PDFJengkol (Pithecellobium lobatum) is one of MPTs that is included of Fabaceae Family. Jengkol seed is counted as recalcitrant, which is could not defend it is viability when it is stored at low temperature and humidity. The study aims were to determine the effect of storage time and storage media to storability of jengkol seed, storage media effective to maintain the jengkol seed viability, and the interaction between the storage media and the storage time to jengkol seed. The reseach design of factorial (3 x 4) in a completely randomized was employed as a research method. The first factor was the storage time (T) which was consisted of T0 (without storage), T1 (2 weeks of storage), T2 (4 weeks of storage), and T3 (6 weeks of storage). Second factor was storage media (M) which was consisted of M0 (without storage media), M1 (sawdust storage media), and M2 (rice husk storage media). For each combination treatment was repeated 3 times. Each unit of experiments consisted of 40 seeds. The observed variables were germinated seeds in storage, the number of germinated seeds, avarage day to germination and germination power. Bartlett test was used to figure out the homogenity of datas. Varians analysis was at least one used to see if there was at least one significant treatment. The smalles significant differences test was used as further test. The entire data were tested on 5% significant level. The results showed that storage of jengkol seed using rice husk for storage media with storage time of 6 weeks gave the best effect for maintaining the shelf life of the seeds. The most effective media to maintain the viability of jengkol seeds is rice husk which can defend the jengkol seeds viability up to 6 weeks of storage.
