: GHRM (Green human resource management) is at a level that needs to be resolved. Needs that need to be immediately resolved are developing valid GHRM measurements and offering more insight into the performance of individuals or organizations. GHRM is divided into five part: green training, recruitment and selection, payroll, involvement and performance management. The safety and healthy environmental need to be applied in manufacturing area. Nowadays research on this topic still have opportunities. The papers that analyzed for research on GHRM from 2015 to support performance improvements in the environment. GHRM application was identified by HR experts with face-to-face views about the practice. This model also proposed the relationship of functions between GHRM functions and environmental management dimensions, which is one of these studies.

: The production of particleboard still uses formaldehyde-based adhesives, such as urea formaldehyde (UF) adhesives, although it has been known that the adhesive is harmful to human health in the long term. Therefore, an effort is needed to get adhesive that is relatively safe to use. One of them is by utilizing tea plant waste which can reduce formaldehyde emissions. The purpose of this study was to evaluate the physical and mechanical properties of particleboard, to evaluate the ratio of waste tea leaves (Camellia sinensis L)and meranti wood ( Shorea sp ) particles, and to evaluate the effect of adding waste tea leaves for formaldehyde emissions produced by particleboard. The results showed that the addition of tea leaf particles can improve the physical and mechanical properties of the particleboard.

: This current work examines the polyisoprenoids (dehydrodolichol or polyprenol and dolichol) profiling and conformation from Norfolk Island pine Araucaria heterophylla (Araucariaceae) and Australian pine Casuarina equisetifolia (Casuarinaceae). The pattern and structure of polyisoprenes were determined by two-plate thin layer chromatography (2P-TLC). The polyisoprene pattern in the leaves was found and categorized into two categories. Group-I, showing a majority of dolichols over dehydrodolichols was detected in A. heterophylla. These dolichols showed as one longer dolichol tribe (C 40 –C 110 ). Group-II, exhibiting the incidence of the pair polyprenols and dolichols, was traced in C. equisetifolia. Dolichol concentrations were faintly extra richness detected comparing to dehydrodolichols (approximately 54%:46%) in this species. Dolichols with chain length of C 75 –C 95 and shorter dehydrodolichol (C 50 –C 55 ) were detected in C. equisetifolia . This study suggested that different pattern of ficaprenols, shorter-chain and longer dolichols are modulated in both pine species.(cid:10)

: Raru is the name for bark that produced by several genus of Dipterocarpaceae such as Cotylelobium, Shorea and Vatica. The raru bark known as important source for traditional medicine of diabetic and mixture of bataknese alkoholic drink called "tuak" for increasing the fermentation rate. The lack of natural regeneration and destructive illegal harvesting for wood and bark, decreased the population every year. Due to this condition, since 1998 this species classified on endangered (EN) based on IUCN Redlist. Previous research showed only one species was found in North Sumatra, but from local community information, there were three local species can be found in Central Tapanuli, those were raru songal, raru dahanon and raru pulut. The objective of our research were (1). To determine the morphological character of local raru species from Central Tapanuli and (2). To determine phylogeny clustering based on morphological characters. Morphological data was collected from direct observation and measurement of on vegetative part of raru trees (stem, canopy, and leaf). Morphological characters were examined using descriptive analysis, phenotypic variability using standard deviation, and cluster analyses. The result showed that there was a difference between three raru species according to 32 observed characters including leaf, stem, bark, crown type, wood and the rosin. Analysis and measurement both quantitative and qualitative characters clustered raru into two groups. In which, raru songal separated with other species.

Quorum-sensing is a specific communication type among microbial species, exposing several virulence factors to host or internal environment. The phenomenon is currently being studied as potential target for drug discovery and development. Natural product derived from plant source may be evaluated as potential quorum-sensing inhibitor (QSI). The study aimed to determine the optimum concentration of Andaliman methanolic (MeOH) and ethyl acetate extract (EtOAc) against prodigiosin synthesis by Serratia marcescens as one of phenotypes controlled by quorum sensing. Based on optical density (OD600), both extracts did not interfere with the growth of microorganism. The optimum concentration of MeOH extract in inhibiting the prodigiosin synthesis was at concentration of 0.05% (w/v) in the end of incubation period (30 h). Meanwhile, the EtOAc extract inhibit the prodigiosin synthesis at concentration of 0.4% in the end of incubation period. Our results showed that Andaliman possess natural products as QSI which needed further evaluation in the future.

: One of the problems that needs to be considered in the captive elephants management is the adequacy of feed. This study aims to obtain information on feed plants species, the palatability value and productivity of elephant feed in Aek Nauli's Special Purpose Forest Region. The research method was carried out by observation, focal animal sampling as well as feed productivity by measurements of changes in growth weight, height and diameter trees. The results showed that at the grazing area elephant have been identified at least 41 species of elephant feed, mainly from the Paoceae, Moraceae, Myrtaceae and Euphorbiaceae Families. The part plant species that most consumed is all parts (grass), leaves, plant skin and fruit. The species that have the highest palatability value (frequency and duration of feed) are Ottochloa nodosa, Caryota gigas and Rhodamnia cinerea. The highest leaf productivity has Arthocarpus integler and Litsea sumatrana is the lowest. Plant characteristics that affect feed growth are diameter and total height with equation (dry weight) is Ybk = 0.079 + 0.103 Diameter + 0.052 Total Height with correlation of 65.5%.
