The existence of forest degradation on Bangka Island due to illegal logging, conversion of land to plantation land, and illegal tin mining by the community and companies on a large scale has caused the mentilin’s habitat to decrease. This study's purpose was to determine the total population of mentilin and determine the habitat of mentilin in the Pelawan Forest. The method used is line transect and vegetation analysis. The results of this study were a total of 6 Mentilin found from two groups and a tree-level diversity of 1.67; Pole 2.48; 3.41 saplings and 3.40 seedlings.

These primates have a local name, “Kedih.” Forest fires and forest functions conversion into oil palm plantations are pressure on their habitat and have decreased wild populations in nature. As arboreal animals, their movements depend heavily on the connectivity of vegetation. Comprehensive research is needed to obtain horizontal and vertical daily movement data of the thomas langur. This study used GPS to take coordinates, a camera to document Thomas langur and its food trees, and Thomas langur as a research object. The data recorded includes the coordinates of each forage tree, the type of forage tree, and the height of the canopy strata used by Thomas langur for foraging. The hardwood movement data was plotted on ArGis 10.1 to get the horizontal hardness movement area. Tree height data was obtained by measuring the tree height where Thomas langur stopped to look for food. Kedih movements to look for food are carried out daily from morning to evening. The results showed that the short length of movement was highly depend on the availability of forage trees. The denser the forage trees, the shorter the daily activities of Thomas langur. This daily movement can be done horizontally and vertically. Horizontally, Thomas langur moved to follow the forage trees, and vertically, Thomas langur moved by utilizing the height of the forage trees. Horizontally, Thomas langur moved 144.92 m in the rehabilitation block and 62.30 m in the protection block. The Thomas langur home ranged in the rehabilitation block is 27 ha, and 25 ha in the protected block.

So that it is necessary to process waste into materials that have useful and even economic value, one of which is Liquid Organic Fertilizer (POC). The purpose of this study was to determine the levels of macro and micro nutrients in POC with varying concentrations of EM-4 bioactivator. In this study, the manufacture of POC with various concentrations of bioactivator 0, 25, 50, and 100 mL with a fermentation time of 14 days. Then carried out physicochemical observations, namely observing physical and chemical changes ranging from viscosity, color, odor and the presence or absence of gas in the POC made. The resulting POC was then tested for macro-nutrients (N, P, K and C-organic) and micro-nutrients (Fe, Mn, and Cu) using AAS and UV-Vis spectrophotometer. In this study, the best POC of onion peel waste was obtained at a concentration of 100 mL bioactivator with macronutrients N, P, K, C-Organic, each of which was 0.71; 1.45; 0.36 and 4.7%; while the content of micronutrients Fe, Mn, and Cu were 0.037, respectively; 0.0052, and 0.198%. It can be concluded that the levels of macro and micro nutrients have complied with SNI 19-7030-2004 except for C-organic elements which are still far below the standard, and POC made from onion skin has a high phosphorus content, so it is very suitable for use in plants that have high levels of phosphorus. require growth regulators (ZPT), especially for root growth.","PeriodicalId":17812,"journal":{"name":"JURNAL SAINS NATURAL","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83106437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Field observations were made by measuring the type and density of flora in the pond by census, and the frequency of biological encounters based on time search for fauna. The results showed that there were 4 types of plants in the ponds, namely mangrove (Rhizophora mucronata), lotus (Nymphaea lotus), needle grass (Adropogon aciculatus), and Moss (Taxiphyllum barbieri).
