The existence of the LPHD is considered important, because it can improve the standard of living of the community around the forest area as well as be able to maintain the stability of the forest ecosystem, one of which is the LPHD Muara Danau, but its management is still considered not optimal in developing agroforestry businesses. This study aims to analyze the performance of the LPHD Muara Danau in village forest management. The research methodology are interviews, observation, and documentation studies. The data obtained were analyzed descriptively. Results showed that the performance of the Muara Danau LPHD was categorized as quite good, this was seen from three aspects, namely institutional, area and business management. The institutional management aspect is measured based on the participation of the management and LPHD members in participating in the activities as many as >75% of the members are present in the activity (91%) and the type of binding group rules in the form of (AD/ART) and unwritten rules (84%) and area management is measured based on types of forest resource conservation activities carried out were 52 people (95%) and the impact that was felt by 2-4 impacts on the environment from Village Forest management was 48 people (87%). However, business management has not yet achieved optimal results, measured based on the absence of local institutions (cooperatives) that carry out marketing of forest products. LPHD agroforestry business development needs to be increased in order to maximize the marketing of forest products.

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.

White oyster mushroom cultivation has been widely recognized by the people in Ciamis Regency on a small or large scale. However, this farming phenomenon experienced many ups and downs. Though the need for mushroom consumption by the market is still quite high. This study aims to determine the extent to which the productivity differences of white oyster mushroom farming are cultivated by farmers in three different business segments and how is the business feasibility. The method used in this study is a survey method. Data were collected through interviews with purposive sampling to mushroom farmers. To find out the productivity and feasibility of farming, a cost, and income analysis approach and R/C. Then a different test is conducted to determine the differences in income between business segments. The results showed that the farming of white oyster mushrooms in the three business segments can generate different incomes. The business segment from baglog to harvest has the highest productivity (R/C 1,16). However, the highest income is generated by white oyster mushroom farming in the baglog manufacturing segment. Financially the three segments of white oyster mushroom farming are feasible because they can generate positive income and R/C>1

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.

Pine forest in South Sulawesi is one of the evidence of successful reforestation and has been utilized by the community in the form of tapping pine resin. This article explains the permits types of the utilization/collection of pine resin by the community, the role of pine resin in community livelihoods, and various problems in the utilization of pine resin by the community in South Sulawesi. Qualitative/quantitative descriptive analysis is used to analyze primary data obtained through interviews and secondary data analysis obtained from relevant agencies. We found that the utilization/collection of pine resin in South Sulawesi by the community used four schemes or permits types, namely: Business License for Non-Timber Forest Product Utilization, Licence for Collection of Non-Timber Forest Products, Social Forestry Schemes Permits, and Cooperation of Forest Utilization. Furthermore, for the community livelihoods, utilization/collection of pine resin has provided extra incomes and employment for local communities and workers from outside. However, labor limitations, fluctuations in the price of pine resin, relying on the community on business partners, and tapping techniques that contradict the principle of forest sustainability is still becoming the problems in the utilization/collection of pine resin in South Sulawesi.

Recently, Indonesian peatland has become global attention regarding several forest fire events, which are seemingly caused by the improper ecosystem management system. Through literature review, this paper discusses one of specific forest formations in peat swamp, namely ramin forest (Gonystylus spp.). An assessment is performed for ramin forest management system from time to time using a framework developed by Indonesian Eco-Labelling Organisation. The criteria applied are sustainability of production, ecological, and social functions. Several recommendation to refine ramin forests are (1) assure new concession permit in any peat swamp areas stops and (2) hasten the implementation of one-map policy as a baseline for further planning and calculating current potency of ramin. For the new regulation, activities can be carried out are (1) to rehabilitate the degraded peat-peat swamp forests, (2) to strictly protect the last pristine ramin forests, (3) to establish seed orchard from seed resources to conserve the germ plasma, (4) to support research into ramin degraded forest restoration and the ecological relationship in pristine ramin forests to better understand how the system works, (5) to recalculate the current diameter increment and to use that to calculate the harvesting rotation, and (6) to uphold forestry law more firmly.

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). The results of forest health monitoring showed that there were 4 plot clusters with the final value of forest health status in the medium category plot 1 (5.63), cluster plot 2 (3.51) poor category, cluster plot 3 (4.92) poor category, and cluster plot 4 (7.57) in good category. Thus the results of forest health monitoring obtained in the mangrove forest of Margasari Village with an average final value of forest health status of 5.41 which is included in the medium category.

The Pecut kuda plant is one of the plants of the genus Stachytarpheta which is found in tropical regions, including Indonesia. In Indonesia this plant is found in East Kalimantan which grows wild. This study aims to determine the type of secondary metabolites and the level of toxicity of the leaves of horse whip (Stachytarpheta jamaicenesis (L.) Vahl). The research stages were sample drying, sample maceration, filtered, concentrated with a rotary evaporator, phytochemical and toxicity tests using linear regression values to determine the LC50 value with SAS probit analysis. Phytochemical test results showed that the pecut horse leaf extract in the n-hexane fraction contained flavonoids, quinones and steroids, the ethyl acetate fraction contained alkaloids, steroids, saponins, flavonoids and quinones and the methanol fraction contained phenolic flavonoids, quinones and saponins. The results of the toxicity test on Artemia salina L. shrimp larvae in the fraction of n-hexane, ethyl acetate and methanol obtained LC50 values of 0.036 ppm, 5.24 ppm and 29.51 ppm, respectively. Based on the LC50 value, it can be concluded that the three fractions are very toxic, but the most toxic is the n-hexane fraction (LC50 = 0.036 ppm).

Conservation forests must maintain the function and quality of their forests so that the preservation of the living natural resources therein is not damaged and the balance of the ecosystem is well ordered. The benefits of a conservation forest can be felt by the people who live around the forest such as carbon, water sources, non-timber forest products so that the community can prosper. Forest health monitoring is an activity designed to monitor the condition of forest health based on the results of measurable ecological indicators for forest management decision making. The purpose of this study is to determine the value of conservation forest health status and identify internal and external factors of conservation forest health. The method used is Forest Health Monitoring for assessing forest health status and Statistical Product and Service Solutions 20. software for determining the relationship of internal factors with external forest health. The results showed the health status of the conservation forest included in the management area of the Sustainable Peoples Forest System Farmer Group in the Teluk Pandan sub-district of Pesawaran District included in the medium category (3,20) . Internal factors that affect the health of conservation forests are biodiversity and tree damage while external factors that affect the health of conservation forests are the level of farmers' knowledge, farmer participation and farmer motivation.
