Abstract

Mangrove forest is a tropical beach vegetation community dominated by several tree species that can grow and develop in tidal and muddy beaches. Some mangrove areas recently have been damaged due to illegal activities carried out by various parties, one of which is the East Coast of Sumatra in the Sub District Percut Sei Tuan, Deli Serdang District, Province of North Sumatra. The purpose of the activities is to focus on replanting mangrove lands that have been damaged by local species. The growned in Tanjung Rejo Village Percut Sei Tuan buds are like Rhizopora stylosa, Rhizopora apiculata and Avicennia marina type. Percentage of growing plants were R. stylosa (92.37%), R. apiculata (90%), mixed propagules of R. stylosa and R. apiculata (90%) and A. marina (56%) respectively. Overall the rehabilitation of mangrove forest is categorized as successful, but only one species of the smallest growing with percentage is A. marina (56%) this is because the location of planting is adjacent to the sea where the plants can not stand the tidal currents.

Abstract

Merapi eruption produced clouds of volcanic material and heat. Volcanic material will close the land with a certain thickness. This will affect the physical, chemical and biological soil. This research was conducted to determine the presence of Phosphates Solubilizing Fungi in the soil of former eruption in Karo regency. The soil samples were taken in areas affected by the eruption at a depth of 0-5 cm and a depth of 5-20 cm, while in areas not affected by the eruption was taken at a depth of 0-20 cm. The results showed the similarities of fungi genus and the differences of fungi phosphate solvent affected by the eruption or land that is not affected by the eruption. There are 2 genus of fungi that are found in all depth of soil, there are Aspergillus and Penicillium. The number of fungi isolates obtained 10 isolates there are 7 isolates of Aspergillus and Penicillium are 3 isolates.Keywords : The eruption of Mount Sinabung, Phosphates Solubilizing Fungi, Phosphates

Abstract

This study aims to determine the impact of the eruption of Mount Sinabung on soil chemical properties in Karo. This study is exploratory in which the comparison between forest land that is not affected by the eruption (control) was taken from the village Kutagugung and forest land affected by the eruption taken from the village Sukanalu. Soil samples exposed to the eruption consisted of two samples that volcanic ash with a depth of 0-5 cm and mixed with volcanic ash soil to a depth of 5- 20 cm, while for the control of soil samples consisted of a sample of the soil to a depth of 0-20 cm. Tests conducted on soil chemical properties BPTP North Sumatra and Central Laboratory of the Faculty of Agriculture, University of North Sumatra. Results showed the soil to a depth of 5-20 cm eruption contains C-Organic, CEC, available P, total P, and S with the criteria of moderate to very high, while the volcanic ash with a depth of 0-5 cm and control soil with a depth of 0 -20 cm contains the C-Organic, CEC, N, available P, total P, K, Ca, Mg and S with the criteria of very low to very high.Keyword: volcanic eruption, Sinabung, soil chemistry, soil depth.

Abstract

Volcanic ash released when the eruption has an acidic pH, thus affecting the amount and activity of microorganisms in the soil. Therefore conducted this study to determine the activity of soil microorganisms in the former eruption of Mount Sinabung in Karo. Measurement of total soil microorganisms was done by Agar Cawan method, while the measurement of the activity of soil microorganisms was conducted jar and titrimetic method. The result of the research showed that the higher of the pH, the colony of microorganism will be much and the reverse. The higher of C- organic, the activity of micoorganism will be high within the soil, and the reverse. Respiration value on land affected by volcanic ash at a depth of 0-5 cm was 0,96. Respiration value on land affected by volcanic ash at a depth of 5-20 cm was 1,16. Respiration value on land that was not affected by volcanic ash was 1,52.Keywords: Volcanic ash, soil microorganisms, microorganism activity, soil depth.

Abstract

This study aims to determine the tree species and tree quality found on five green belt in Pematangsiantar. This study was carried out along the Medan road, Sisingamangaraja road, Rakutta sembiring road, Ahmad yani road and D. I Panjaitan road. This research used census and scoring methods. Assessment conducted of tree health involved trunk health and crown health,and then the technical of trees involved threat to buildings, threats to roads, sidewalks and drainage, and threats to electric and telephone wires. Results showed that tree species found in five green belt as much as nine trees. The trees most often found are mahogany (Swietenia mahogani). The quality of trees in five green belt when viewed from the tree health included in light category, and from technical trees included in moderate category. The most good quality tree located on Ahmad yani street, while the most low quality trees are on the Rakutta sembiring street. This is indicated from the cumulative value ≥2,5 on Rakutta sembiring road has the highest percentage that is 14,93 %.Keywords : Green belt, Tree species, Tree quality

Abstract

This research aims to find out the response or effect of arbuscular mycorrhizal inoculation on growth of slow growing plant. This research was conducted in the greenhouse of the Faculty of Agriculture, University of North Sumatra, Medan.This research uses completely randomized factorial design with 2 factors namely mycorrhizal doses (0 g / seed, 5 g / seed, 10 g / seed, and 15 g / seeds) and plant species (glodokan and tanjung). Parameters measured were plant height, plant diameter, leaf number, percentage of root colonization, P uptake, total dry weight, and short root ratio. The results showed the interaction between plant species and dose mycorrhizal not significantly affected all parameters of eachs treatment. Conversely single factor plant species showed significant effect on all parameters of each treatment, but to a single factor dose of mycorrhizal significant effect on the total dry weight and P uptake but no significant effect on the parameters of height, diameter, number of leaves, the ratio of the root crown and root colonization. Different types of plants  will give a different response to growth.Keywords: Mycorrhizal Fungi, Tanjung, Glodokan, Marginal Land

Abstract

Existence and status of the AMF is influenced by biotic and abiotic factors. This research aims to study and know the status and existence of Arbuscule Mycorrhizal Fungi (AMF) on the land productive and non productive land. Soil samples derived from the productive and non productive land in Tanjung Anom. This research uses the filter to get the spores and staining method to determine root colonization. Results showed that AMF colonization in productive land obtained 17.83% with an average density of 80 spores / 50g soil, and the percent of AMF colonization in non productive land obtained 42.76% with an average density of 89 spores / 50g  soil. AMF spore types Glomus and Acaulospora on productive land obtained 13 spore types Glomus sp, and on non productive land obtained 14 spore types Glomus sp and 2 Acaulospora spore types. Total spore types were obtained 27 spore types, 25 types of spores Glomus sp and 2 Acaulospora sp spore types.Keywords : Productive Land, Non Productive Land, AMF, Spore, Colonization.

Abstract

Volcanic dust expelled while eruption have a sour potential of hydrogen and the result led to a decrease in the diversity various and microorganism population. The fungi are important instrument in the process of decomposition of organic material for all types of soil. The fungi selulolitic have the ability to hydrolyze the cellulose naturally through it’s cellulose activity. This research aims to study the presence of selulolitic fungi contained on land under forest stands are former eruption of Sinabung Mountain in Karo District. Soil sampling was done with diagonally composite. Soil samples exposed to the eruption consisted of two samples that volcanic dust with a depth of 0-5 cm and mixed with volcanic dust soil to a depth of 5-20 cm, while for the control of soil samples consisted of a sample of the soil to a depth of 0-20 cm. The isolation of fungi and identification were done in the laboratory of Soil Biology, Agroecotechnology, Faculty of Agriculture, University of Sumatera Utara. This research was carried out from March 2015 until May 2015. The results showed that there were 4 types of selulolitic fungi found in soil samples affected by volcanic dust and are not affected by volcanic dust, namely Aspergillus, Penicillium, Rhizopus, and Trichoderma.Keywords : volcanic dust, former eruption land, cellulose, selulolitic fungi
