Abstract

Arbuscular Mycorrhizal Fungi (AMF) are cosmopolitan is almost found in a variety of ecosystems. Forest fires influence the biological properties of the soil, especially AMF. This research aims to study the status and diversity of AMF in the former soil of forest fires. Samples of soil and roots of plants was taken from the location of the fire in separate incidents during the 5 period and location unburn. Parameters observed that the degree of root infection, spores density and identification of the type of spores. Identification of mycorrhizae conducted at the Laboratory of Soil Biology, Faculty of Agriculture, University of North Sumatra, begin in May until September 2014. Morphology characteristics used to identify the type of AMF is a form of cell wall thickness, presence or absence of substanding hyphae, surface smoothness and spores  reaction to melzers. The results show that an increase in the average density of spores from the field and the results of trapping, for the average percentage of AMF colonization in the roots of plants at 50,65% include grade 3 and 4 or high categories. Found 2 genus, namely Genus Acaulospora and Genus Glomus. Of the field found as many as 35types of spores and trapping results are found as many as 40 types of spores.

Abstract

Plumbum (Pb) is an environmental contaminant that risk for human’s health, reducing soil fungtion and productivity and damage for plants. Therefore, remediation is need to do such as bioremediation using AMF and sengon as a host. A research was conducted to knowing the effect of the addition of AMF for Pb content on Sengon in green house of Agriculture USU. Analyze of Pb metal was done at Research Laboratory of Pharmacy USU on October 2014- February 2015 using faktorial completely randomize design with two faktors, i.e Pb addition (0 and 400 ppm) and doses of mycorrhiza inoculation (0, 25 and 50 g). Parameters measured were root colonization, plant height, stem diameter, root drying weight, crown drying weight, crown root ratio, root Pb content, crown Pb content and soil Pb content after harvest.The results showed that Pb addition affected significantly on plant height, Pb content on root, crown and soil after harvesting parameter. Inoculation of mycorrhiza affected significantly on plant height, stem diameter, drying weight of root and crown. Inoculation of mycorrhiza did not significant on Pb content but capable to increasing Pb content on root, crown and soil. The interaction of the two faktors did not affected significantly on all parameters. Key words: Sengon, Pb, AMF

Abstract

Lubuk Kertang Village has the potential for mangrove ecotourism which is currently being developed as a source of income for the community's economy apart from fishermen and agriculture. Even the mangrove ecosystem in Lubuk Kertang Village has become a tourist icon for Langkat. Apart from mangrove ecotourism, Lubuk Kertang is also unique with its processed mangrove products in the form of foods such as mangrove dodol, jeruju crackers, and mangrove syrup. However, productivity is constrained by the availability of mangrove fruit which depends on the season. Moving on from this, it is necessary to carry out community service activities to provide education about the potential and benefits of mangrove waste in the form of stems, twigs, leaves, and fruit from other aspects. Namely that apart from being processed as food material, mangrove waste can also be processed into other high-value products, one of which is a natural dye. Activities carried out are in the form of socialization and education about the potential and benefits of mangrove waste as a natural coloring agent to the manufacturing process. Furthermore, the natural dyes that have been produced are applied in the coloring process through the ecoprint workshop/training. The media used are cloth/textiles, paper, sheepskin, and ceramics (mugs). The response of the community, represented by women from independent women farmer groups as well as some students of Madrasah Tsanawiyah and the Village Head was very good. Even some mothers from independent women farmer groups routinely continue to make ecoprints in the form of cloth, pashmina, and t-shirts. Their products have also been included in exhibition activities in Lubuk Kertang Village. The Head of Lubuk Kertang Village hopes that there will be sustainability from independent women farmer groups to make ecoprint products to increase income from the Lubuk Kertang community. Abstrak Desa Lubuk Kertang memiliki potensi ekowisata mangrove yang saat ini terus dikembangkan sebagai salah satu pemasukan sumber pendapatan ekonomi masyarakat selain nelayan dan pertanian. Bahkan ekosistem mangrove di Desa Lubuk Kertang menjadi ikon wisata Langkat. Selain ekowisata mangrove, Lubuk Kertang juga khas dengan produk olahan mangrovenya berupa makanan seperti dodol mangrove, kerupuk jeruju dan sirup dari buah mangrove. Namun produktivitasnya terkendala oleh ketersediaan buah mangrove yang tergantung dengan musim. Beranjak dari hal tersebut maka perlu dilakukan kegiatan pengabdian pada masyarakat untuk memberikan edukasi tentang potensi dan manfaat limbah tanaman mangrove baik berupa batang, ranting, daun dan buah dari aspek yang lain. Yaitu bahwa selain dapat diolah sebagai bahan pangan limbah tanaman mangrove juga dapat diolah menjadi produk bernilai tinggi lainnya, salah satunya sebagai pewarna alami. Kegiatan yang dilakukan adalah dalam bentuk sosialisasi dan edukasi tentang potensi dan manfaat limbah tanaman mangrove sebagai zat pewarna alami hingga proses pembuatannya. Selanjutnya pewarna alami yang telah dihasilkan diaplikasikan dalam proses pewarnaan melalui kegiatan workshop/pelatihan ecoprint. Media yang digunakan adalah kain/tekstil, kertas, kulit domba dan keramik (mug). Respon masyarakat yang diwakili oleh ibu-ibu kelompok tani wanita mandiri serta beberapa siswa Madrasah Tsanawiyah dan Kepala Desa sangat baik. Bahkan beberapa ibu-ibu dari kelompok tani wanita mandiri secara rutin terus membuat olahan ecoprint berupa kain, pashmina dan kaos. Hasil produksi mereka juga telah diikutserakan pada kegiatan pameran di Desa Lubuk Kertang. Kepala Desa Lubuk Kertang mengharapkan adanya keberlanjutan dari kelompok tani wanita mandiri untuk membuat produk-produk ecoprint dalam rangka menambah pemasukan dari masyarakat Lubuk Kertang.
