Wan Abdul Rachman Forest Park (Tahura WAR) is one of the forest areas in Lampung Province. Tahura WAR has a fairly high diversity of flora, one of which is the bamboo plant. There is not much data related to the diversity of bamboo plant species found in Tahura WAR, especially in the Utilization Block. As an effort to develop the potential of bamboo, it is necessary to conduct research on the diversity of types and distribution patterns of bamboo plants. The purpose of this study was to analyze the diversity of bamboo plants and their distribution patterns in the Tahura WAR Utilization Block. This research was conducted in May 2020 in the Tahura WAR Utilization Block, using the river transect method along the 720 m length and 4 m width. The results showed that there were four types of bamboo plants in the Tahura WAR Utilization Block, namely Gombong bamboo (Gigantochloa pseudoarundinaceae) and Tali bamboo (Gigantochloa apus), Ater Batu bamboo (Gigantochloa atter) and Betung bamboo (Dendrocalamus asper. These four species showed a level of diversity bamboo plants that are categorized as low and the distribution pattern is random.

The growth rate of Paraserianthes moluccana is effected by the planting medium quality. Biochar is a soil-improving agent that could improve soil quality. This study aimed to determine the effect of biochar made from meranti wood (Shorea spp.) by pyrolysis temperature at 400°C and 600°C and dose at 0 ton/ha, 25 ton/ha and 50 ton/ha factors through the growth rate of P. moluccana. The P. moluccana was planted within 2x2 m in the field. The size of planting holes was 100 x 60 cm, the biochar was placed at a depth of 100 cm to 20 cm, then it was covered with soil so that the root did not interact directly to the biochar. This research used 6 months old P. moluccana seedling, and was planted in field demplot for 8 months. The research used the Split Plot experimental design with 5 treatments and 7 repetitions. Data analysis used Analysis of Variance (ANOVA) and Least Significance Different (LSD). The effect of biochar could be seen since the 4th month of plantation. The results showed that biochar with a dose of 25 ton/ha and pyrolysis temperature of 600°C had a very significant effect on the increment of height and significant on diameter steam increment of P. moluccana; increased the rate of stem height 22.6% and stem diameter 23.6% faster than the control. Further research related to the dynamics of P. moluccana growth with a longer time is needed because the physical properties of biochar change over time.

Mangrove forest ecosystems can be interpreted as a unique and distinctive form of ecosystem, so that it is able to provide many benefits, ranging from socio-economic or ecological terms to the surrounding ecosystem. Mangrove forest in Margasari Village is a mangrove forest ecosystem that has physical, economic and ecological potential that needs to be maintained through sustainable forest management. One of the ways to manage mangroves is by monitoring forest health. Forest health monitoring that is applied periodically within a forest type can achieve sustainable forest management achievements so as to support better forest quality and quantity and can be a reference in making the right decisions in mangrove forest management so that the results obtained can be optimal. This study aims to obtain the value of the health status of mangrove forests in East Lampung Regency in order to ensure the sustainability of the forest. The study was conducted using themethod Forest Health Monitoring (FHM).

Three slopes of 100 m long are defined in young secondary forest with gentle and slightly steep slopes. In each part of the slope, we built 1 (one) PUP of 20m x 20m which is consisted of 3 (three) Sub PUPs of 10m x 10m to represent the density of sparse, medium, and dense understorey and 1m x 1m of sub-PUPs for litter harvesting. In 18 (eighteen) PUPs, each 54 (fifty-four) Sub PUPs and Sub sub PUPs, were made in this study. The HPFU area is dominated by young secondary forest coverage with gentle and slightly steep slopes. The C reserves of the herbaceous understorey are more significant than that of woody plants. C reserves of all components studied in the gently sloping area are larger than the steep ones. The largest C reserves are found in leaf litter for all slope positions except for a slightly steep lower slope. The largest C reserves is found in finer litter. The total C reserves of understorey and young secondary forest organic litter in HPFU 933.4 tons and 95.9 percent are stored in a litter.

Bio-induction on the branch of agarwood tree (Gyrinops versteegii) is a good alternative method to increase resin productivity. The aim of this research is to applied bio-induction on the branch of G. versteegii with different diameters. Different branch diameter was the treatment on this research including branch 1 (diameter 70 mm ± 5 mm), branch 2 (85 mm ± mm), branch 3 (100 mm ± mm). Fusarium solani isolate of Institute for Technology Research and Development of Non-Timber Forest Product was used as a bio-induction agent. This isolate was cultured on bean sprout broth media for 28 days. Bio-induction was carried using standard procedure developed by Forest Research and Development Agency. Observation of the result conducted 3 months after bio-induction. There were 3 parameters of bio-induction result including resin area production, discoloration in form of browning on branch, and fragrance level of resin. Branch 2 has the largest resin area production. However, branch 3 has the highest score of browning and fragrance level. This result indicated a correlation between browning on branch and fragrance level quality. It could be concluded that bio-induction on larger branch diameter could produce higher productivity of resin, especially on browning and fragrance level parameter
