Abstract

Orchids are plants that have many types and are spread all over the world. Natural orchids generally grow well in natural forests, especially in mountainous areas. Inventory needs to be done to obtain data and information about the presence of orchid species. This research was conducted in January-February 2017. The research was conducted in Gunung Batuah Traditional Forest, Gunung Raya District, Kerinci Regency, Jambi Province with the method of exploration in the plot at an altitude of 1100 m asl-1400 m asl and 1500 m asl-1650 m asl. The results showed that there were 22 types of orchids found in the research location which were included in 14 genera, where there were 16 types of epiphytic orchids, 4 terrestrial orchids and 3 types of saprophytic orchids. The most common orchids are the genus Bulbophyllum, the genus Liparis and the genus Appendicula. Most individuals are in the type of orchid Bulbophyllum lobbii. Orchids are mostly found at an altitude of 1500 m asl-1650 m asl. The habitat trees that were mostly planted with orchids were Syzigium sp, Litsea Angulata and Vitex heterophylla which were scattered in zone 1 to zone 4.

Abstract

Plant biomass is a carbon storage. The amount of biomass depends on the vegetation. This study aimed to analyze and predicted the above ground biomass stock in KPHP Unit X Tebo Timur. Regression analysis was used by correlating the biomass value from field measurement and the NDVI value from Landsat 8 imagery. Some of the regression equations tested were: linear, exponential, quadratic and rank. The best regression equation is used to estimate the biomass stock in KPHP Unit X Tebo Timur. The best model used to estimate above ground biomass stocks based on the NDVI value in East Tebo KPHP is quadratic with the equation Y = 574.05 ((NDVI) 2) - 17.24 (R2 = 85.5%). The analysis results showed that the above ground biomass stock in KPHP Unit X Tebo Timur was 9,695,091.39 tons.

Abstract

Medan Baru is a sub-district in the downtown area, a trade and service area. The higher population growth causes a limited area of ​​an area to provide oxygen needs. Green open space filled with trees as the city's lungs is a producer of oxygen that has not been replaced. This study aims to map green open space using Landsat 8 OLI satellite imagery and estimate the need for green open space in Medan Baru District. This research was conducted for three months (April - June 2019). The analysis carried out is the NDVI transformation (Normalized Difference Vegetation Index), CO2 absorption, and O2 requirements. The NDVI transformation analysis results show that a rather dense density class dominates Medan Baru District. The analysis of green open space as an absorber of CO2 was 7569.17 tons/year. The need for O2 is 86.458 kg/day or an area of ​​0.1708 ha, and the available amount is 65.777.06 kg O2 / day or an area of ​​129.93 Ha so that when compared to RTH to oxygen demand with the area of ​​RTH currently available, it is still sufficient.

Abstract

The aim of this research is to make an effort to utilize forestry waste, in the form of harvesting waste of acacia (Acacia mangiumWilld.) and coconut shells (Cocos nucifera L.) into particle boards by considering the evaluation of the value of particle board characteristics, both physical and mechanical characteristics in accordance with standards JIS A 5908-2003.This study used a factorial analysis where the first factor was the composition of the raw material for acacia: coconut (100: 0, 60:40, 50:50, 40:60 and 0:100). While the second factor is the provision of pretreatment on particles (cold soak, hot soak and without immersion).This analysis was carried out in a completely randomized design (CRD) with three repetitions.The results showed that the composition of the raw materials had a significant effect on the value of water content, water absorption, modulus of rupture and modulus of elasticity.The pretreatment had a significant effect on the thickness swelling, water absorption, modulus of rupture and modulus of elasticity. Meanwhile, the interaction of these two factors has a significant effect on the internal bond value, modulus of rupture and modulus of elasticity.Based on the results, it is known that only the density parameters that meet the JIS A 5908-2003 standard, the moisture content and thickness development parameters have not met the standards, while the mechanical characteristics of the particle board have not met the standards.Overall particle board with the composition of acacia raw material: young coconut 60:40 and heat soaking pre-treatment can produce good quality particle board.

Abstract

Indonesia is a country that has a high biodiversity, both in the diversity of flora and fauna. Indonesia has about 40.000 biodiversity types of plants that are useful for human life. Plants are one of the biological resources that are available in nature. Plants are widely used by the public both as food medicines, rituals, cosmetic materials, animal feed and so forth. The utilization of plant species depends on the surrounding area, for example in mangrove forests. Jambi Province has a Coastal area that is located in Tanjung Jabung Barat and Tanjung Jabung Timur. Coastal communities are people who live in coastal areas that have different characteristics Coastal communities have interactions with mangrove ecosystems so that people use mangrove plants as food crops, medicines, building materials (boards), traditional ceremonies and for household appliances. This research was conducted in June-August 2020 located in Mendahara Ilir Village, Lagan Ilir Village and Sinar Kalimantan Village, Mendahara District, Tanjung Jabung Timur, Jambi Province. The method in this study is explorative Descriptive. Data collection techniques in this study consist of four stages, namely: literature studies, interviews, field observations and herbarium making. There are 14 species of plants that can be used as food ingredients in the community around East Coast Mangrove Nature Reserve.

Abstract

The aim of the study is to analyze the dynamics of Macaranga gigantea for 12 years from 2005 to 2016. The indicator used is the Important Value Index (INP) which includes density, dominance and type frequency. Measurements on trees up to 10 cm in diameter, carried out on a permanent plot derived from light, heavy and medium cuts, with each sample plot covering an area of 3 ha. Identification has found 11 species of Macaranga spp. The species that dominates the highest INP is M. gigantea, followed by M. hypoleuca and M. triloba. The results of the analysis showed that Type M. gigantea had the highest number of individuals during 12 years of observation and that the presence of Type M. gigantea had reached the highest number in 10 years after fire disturbances. In addition, the type of M. gigantea present in forest research areas due to light logging is 2 (two) times more than heavy cutting because the heavy cutting of the area is very open to competition between species of pioneer plant.

Abstract

This research was carried out with the aim of examining the effect of providing palm oil mill effluent (LCPKS) on several soil chemical properties (pH, C-organic, and CEC) and the growth of oil palm seedlings in the main nursery. The research was conducted for 5 months, starting from March 6, 2020 to August 15, 2020 in the main nursery area for oil palm plantation companies, Belanti Jaya Village, Mersam District, Batanghari Regency, Jambi Province. The research was conducted using a Complete Acaka Design (CRD) based on the age and height of the oil palm seedlings that were uniform. The treatments used were based on the POME dosage, namely 0 L, 4 L, 5 L, 6.6 L, 10 L, and 20 L POME given every week for 20 months. Each treatment was repeated 4 times so that 24 experimental units were obtained and each unit consisted of 4 oil palm seeds so that the total number of seeds used in the study was 96 oil palm seeds. In the maintenance of seedlings, inorganic fertilizers were also given using compound fertilizers, namely NPKMg 15: 15: 16: 4, NPKMg 12: 12: 17: 2, and kiserit. The results showed that POME could increase pH from acidic to slightly acidic to neutral, C-organic from very low to moderate to very high conditions, but it could not increase soil CEC. The highest increase in pH and C-organic occurred in the 20 liter POME treatment. The provision of POME was able to increase height increase, increase in stem diameter, increase in the number of leaves, shoot dry weight, dry weight of the roots of the roots, and be able to provide an index of seed strength so that the seeds were able to be transferred to the field with seedlings of 9 months. The highest increase in oil palm seedling growth occurred in the 4 liter POME treatment.

Abstract

Invasion by invasive species represents one of the greatest threats to biodiversity worldwide, causing degradation and loss of habitat. Among them, one species belonged to the Verbenaceae family, namely Lantana camara, which includes 100 of the world’s worst invasive species. Distinguishing invasive from non-invasive species based on morphology alone is often difficult for plants in a vegetative stage, especially in Lantana, where they have complex morphological characters. In this regard, DNA barcoding may become a good alternative. This study aimed to select and provide a DNA barcode region that capable of distinguishing the invasive and non-invasive Lantana. Four DNA Barcode markers available in the sequence database (NCBI and BOLD), namely matK, rbcL, psba-trnh, and ITS2, were used to identify the invasiveness of various Lantana. A total of 132 data sequences from 17 species of Lantana were collected. The sequences were aligned and constructed into a dendrogram using MEGA X through the Neighbor-Joining method. This study shows that it is possible to distinguish Lantana camara from a series of closely related congeners by plastid base gene (matk and rbcl). The constructed phylogeny tree shows that invasive species Lantana camara was in a different clade with non-invasive Lantana.
