Abstract

Desa Pulau Sembilan merupakan desa yang terletak di wilayah pesisir pantai timur Sumatera Utara yang kondisi hutan mangrovenya telah rusak sebagai akibat aktivitas pembuatan tambak udang. Tanpa upaya peningkatan kesadaran dan ilmu pengetahuan pada masyarakat kondisi ini akan semakin berlarut-larut yang berdampak pada meningkatnya kerusakan lingkungan. Kegiatan pengabdian ini bertujuan untuk meningkatkan kesadaran masyarakat dan penerapan ilmu pengetahuan dan teknologi dalam rangka rehabilitasi dan meningkatkan minat masyarakat untuk menanam mangrove. Dalam kegiatan penerapan Ipteks ini digunakan berbagai jenis fungi yang sudah didapat pada kegiatan penelitian terdahulu. Fungi-fungi tersebut diperkirakan berperan dalam mempercepat proses dekomposisi serasah, sehingga unsur-unsur hara yang dibutuhkan oleh bibit mangrove lebih cepat tersedia. Jenis-jenis fungi yang diaplikasikan pada kegiatan penerapan ipteks ini adalah Aspergillus sp. 1, Aspergillus sp. 2 dan Curvularia lunata. Propagul mangrove yang digunakan dalam kegiatan berasal dari mangrove Rhizophora mucronata. Kegiatan penerapan Ipteks dapat berjalan lancar, masyarakat sangat antusias menerima sosialisasi yang disampaikan dan antusias dalam mengikuti seluruh kegiatan mulai dari pembibitan sampai kegiatan penanaman. Aplikasi fungi C. lunata memberikan dampak pertambahan tinggi yang lebih besar yaitu, rata-rata 1.88 cm setelah 7 minggu aplikasi. Adapun bibit R. mucronata yang diberi aplikasi fungi Aspergillus sp. 1 dan Aspergillus sp. 2 setelah 7 minggu perlakuan menunjukkan pertambahan tinggi yang lebih kecil, yaitu ratarata 1.63 cm dan 1.65 cm. Pertambahan tinggi bibit yang diberi perlakuan lebih besar dibanding kontrol. Diameter batang bibit R. styl R. mucronata osa yang diberi aplikasi fungi C. lunata, yaitu rata-rata 0.4 cm. Adapun diameter bibit R. stylosa yang diberi aplikasi fungi Aspergillus sp. 1 dan Aspergillus sp. 2, yaitu masing-masingnya 0.38 cm dan 0.35 cm. Diameter batang bibit R. mucronata kontrol lebih kecil dibanding diameter batang bibit R. mucronata yang diberi perlakuan dengan berbagai jenis fungi, yaitu 0.25 cm.

Abstract

Mangroves are a unique ecology that resides in places with salinity, which are inundated at low tide when there is no flooding and at high tide. Mangrove forests that are increasingly damaged cause the quality and quantity to decrease. Using different species of fungi that can accelerate the growth of mangroves is one attempt to increase and get high-quality mangrove seeds. This study aims to shed light on the fungi that can dramatically improve the growth of Avicennia marina seedlings. Mangroves can absorb organic and non-organic materials produced by decomposing microorganisms, which come from leaf litter or other decomposed materials. In this experiment, several fungal species were used, including Aspergillus niger, Aspergillus sp. 2, and Aspergillus sp. 1. The findings demonstrated that the fungus might speed up A. marina seedling growth. The plant's height, diameter, leaf width, and total dry weight were all altered as a result. Based on the study's findings, it can be said that Aspergillus niger provided the best growth for A. marina seedlings

Abstract

Influence on the growth of Rhizopora apiculata seedlings given fertilizer Beauveria, Mycorrhiza, Trichoderma or not given fertilizer. Mangrove forests are the main ecosystem supporting life activities in coastal areas and play an important role in maintaining the balance of biological cycles in the environment. The purpose of this study was to determine the effect of Beauveria fertilizer, Trichoderma fertilizer, mycorrhizal fertilizer and not given fertilizer on the growth of Rhizophora apiculata seedlings. This study used a complete randomized design (RAL) consisting of 4 treatments with 10 repetitions. The treatment was carried out with P0 = control, P1 = Beauveria, P2 = Trichoderma, P3 = Mycorrhiza. From the data of observation of seedling height, seedling diameter, it can be concluded that the effect of fertilizer does not affect plant growth and can be declared insignificant.

Abstract

Nickel (Ni) doped in the perovskite manganite could result in superior properties. The effect of the Ni on the morphology, crystallographic orientation, and magnetic properties of La0.7Sr0.3Mn(1-y)Ni(y)O3 alloy (y = 0.1, 0.3, 0.5, and 0.7), therefore, was undertaken. La0.7Sr0.3Mn(1-y)Ni(y)O3 alloy was firstly processed using a ball milling process, and again processed through heat treatment and crushing at the end of the synthesis process. Powder alloy was then investigated using a scanning electron microscope equipped with scanning electron microscope and energy dispersive spectroscopy (SEM-EDS), x-ray diffraction (XRD), and vibrating sample magnetometer (VSM). The particle size became smaller and agglomerated as the amount of Ni doping increased. The polycrystal structure phase formed would become more complex when the Ni doping was 0.5 and 0.7, where the dominant phase formed was La2NiO4 even though the La0.7Sr0.3Mn(1-y)Ni(y)O3 phase was still formed. The magnetic characteristics showed that the Ni doping of 0.1 had a higher magnetization value around 4.2 emu/g at room temperature.

Abstract

The existence of mangrove ecosystems decreases from land conversion into residential areas, industries, plantations, road facilities and the construction of ponds. This research was conducted in the mangrove forest area of Secanang Belawan Village, Medan, at the Biotechnology Laboratory of the Department of Forestry, Faculty of Agriculture, USU and at the Microbiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, USU Medan. The study's objective was to identify the different fungal species that were present at 10 ppt salinity levels, 10–20 ppt, and 20–30 ppt as well as the pace at which Avicennia marina leaf litter. The research method used litter bags filled with leaf litter of Avicennia marina (50 g) with 7 treatments, 3 replications and 3 levels of salinity. The A. marina leaf litter that had a salt level of 10 ppt had the highest level of decomposition. The dry weight of leaf litter left in the litter bag, which is 4.92 g on average. The largest dry weight of the remaining litter was found in an environment with a salinity of 20 – 30 ppt, which is an average of 10.42 g. The rate of decomposition of A. marina leaf litter in an environment with a salt level greater than 30 ppt is 6.53/yr (or almost equal to residence period of = 0.15 yr). The number of fungal species discovered in the leaf litter of A. marina, which goes through a breakdown process at salinity levels between 0 and 10 ppt and contains 9 species, is another way to observe the impact of salt level. In comparison to the large at salinity levels of 10 to 20 ppt and 20 to 30 ppt, respectively, there were populations of fungus that underwent the process of decomposition in A. marina leaf litter, with an average of 5.99 x 102 cfu/ml and 5.5 x 102 cfu/ml, the fungal population that was the highest concentration was 10.72 x 102 cfu/ml

Abstract

Forest ecosystems can absorb greenhouse gases by absorbing CO2 from the air to store carbon in vegetation. The IPB Darmaga Campus Bamboo Arboretum is one of the green opn spaces on campus in an effort to reduce environmental pollution in the city. The aim of this research is to describe species composition, vegetation structure, estimate biomass potential, carbon storage and carbon dioxide (CO2) uptake, as well as describe soil properties in the Bamboo Arboretum, IPB Darmaga Campus. The method used is measuring diameter and height (trees, poles, stakes, dead wood and dead trees) as well as measuring the water content of undergrowth, seedlings, litter and twigs. Soil data collection was carried out using the purposive sampling method. The research results show that the species composition of the forest stands at the Bamboo Arboretum on the IPB Darmaga Campus is dominated by Hevea brasiliensis (rubber zone and Dipterocarpaceae zone), Bambusa blumeana (bamboo zone), and Swietenia mahagoni (mixed zone). The rubber zone is the zone with the highest value of biomass, carbon storage, and carbon dioxide uptake. The soil organic C content in the Bamboo Arboretum of the IPB Darmaga Campus in the Dipterocarpaceae zone, rubber zone and bamboo zone is high, while in the mixed zone it is medium.
