Mangrove litter leaf represent the organic substance supplier towards fertility of mangrove ecosystem, that able to support the mortal life within. The area of forest of mangrove represent the nursery ground, feeding ground, and area of spawning ground for various fish type, prawn and other biota sea and also as producer of amount of detritus for plankton as main foods source of the sea. The objectives of this research were to know production and decomposition rate of mangrove litter leaf in the mangrove ecosystem of Durian Village and Batu Menyan Village, Padang Cermin subdistrict, Pesawaran regency. Data was analysed by calculating the dry weight mean of litter leaf production and to counting decomposition rate was using the exponential rank function or from absolute decomposition percentage of litter leaf per day. This research was conducted in two place (station) based on the difference of substrate characteristic. The research conducted from October to December 2013. The productivity of mangrove’s litter leaf in both places is 0,56 g/m2/day, where the leaf organ gave the higgest contribution, (66%), stick and branch (14%), flower and fruit (20%). Decomposition rate of mangrove litter leaf showed that at the second station ( 0,20 g / hr) was faster than the first station ( 0,19 g / hr).

Wulandari C, Bintoro A, Rusita, Santoso T, Duryat, Kaskoyo H, Erwin, Budiono P. 2018. Community forestry adoption basedon multipurpose tree species diversity towards to sustainable forest management in ICEF of University of Lampung, Indonesia.Biodiversitas 19: 1102-1109. Integrated Conservation Education Forest (ICEF) of University of Lampung (Unila) at Wan AbdulRachman (WAR) Forest Park is a conservation forest which should be free from any kinds of human activities. In fact, more than 75%the area has been managed by community hence there is a need for management strategy through Community Forestry (CF). It is knownthat there are a lot of Multipurpose Tree Species (MPTS) that can be utilized for the community’s daily life. The research’s objectivesare to analyze the ability of the community to adopt CF scheme, to calculate the diversity index of MPTS and level of Skill KnowledgeAttitude (SKA) and to determine the correlation variables to sustainable CF. This study used Shannon-Wiener diversity index, analysisof SKA level and regression analysis for adoption level. The results of this study noted that at the research site has diversity index 0.115and 74.29% of plants are MPTS. Based on the data analysis, 168 respondents [89%] agree to adopt CF scheme and level of their SKA ismoderate therefore needs to increase this level towards to forest sustainability. There are three variables of community forestry adoptiontoward to sustainable forest management at ICEF: number of trees species, the volume of forest products that would be sold, and rolesof extension education.
Medicinal plants have long been used by traditional communities, one of them is the Malay people in Lingga Regency, Riau Islands Province in healing various diseases. This study aims to determine the types of medicinal plants based on local knowledge of the indigenous Malay people. The population of this research is the native Malay people of Lingga Regency and the sampling is done using the snowball sampling method so that the selected respondents are following the required data. This type of research is descriptive research with qualitative and quantitative methods. The qualitative method was used to find out the use of medicinal plants used by the community by interview while the quantitative method was used to find out the percent of the use of medicinal plants by the Malays from the interviews. Based on the results of the study there were 102 types of medicinal plants in 53 families. The most commonly used plant parts are leaves (45.10%) by boiling and the least used are seeds and bark (1.96%). The most used habitats were herbs (27.45%) and trees (26.47%) and the least used were liana (8.82%) and terna (3.92%). Diseases that are usually treated by people with plants are diseases that are commonly suffered by ordinary people such as fever, diarrhea, coughing, toothaches, itching and mouth sores.
The demand of mirabow wood is increasing nowdays, where as the existence species in the nature is getting reduced. Therefore, it’s preservation efforts are urgent to be done. Seed size was correlated with it’s vigor, where heavy seeds relatively have a better vigor, compare to the light one. The research was aimed to determine the effect of seed size to percentage of germination, average days to germinate, germination value and germination power of mirabow seeds. The research was conducted in greenhouse of Agriculture Faculty Lampung University on November 2013 to January 2014. The research was arranged in Complete Random Design (CRD), with 3 treatments and 4 replications. Seed are classified based on the weight of seed is heavy weight, medium weight, and light weight. Each unit of experiments was used 100 mirabow seeds. The observed variables were consisted of germination percentage, average day to germination, germination value, and germination power. Data analysis methods used were homogeneity of variance, variance analysis, and least significant of difference test at 5% significant level. The results showed that seed size of mirabow has a positive effect to the germination. The heavy weight of seed (> 3.49 grams) gave a better response for germination percentage 80.250% and germination value 1.595 %/day compared with the medium weight (2.36--43.49 grams) and light weight (< 2.36 grams).

Forests had an important role in carbon reserve and uptake: where this was one of efforts of global warming’s impacts mitigation. The aim of this research was to know the effect of density in potential of carbon reserve and uptake in the private forest. Data collection was carried out by survey; then the collected data were analyzed for tree biomass, necromass, litter and ground plants, total of carbon stock in one area, suitability of carbon stock, CO2 absorbtion, and the differences in carbon stock and carbon uptake in each of density class. The result showed that, forests with low density were significantly lower in stored carbon and CO2 absorption, respectively 54.57 tons/ha and 200.27 tons/ha. In medium and high density forests, both the amount of stored carbon and CO2 uptake were no different. At medium density, stored carbon was 79.78 tons/ha, and CO2 absorption was 292.79 tons/ha. In high density, stored carbon was 92.94 tons/ha and CO2 absorption was 341.09 tons/ha.
