The Marginal Land in Indonesia still in very large amount. Meanwhile, the accelerate to rehabilitate the land still very slow. The low of pH, C-Organik, N-Total, P and K-exchangeable become the parameter of marginal land condition. Therefore carried out research which combine acid humic and NPK fertilizer which applied to marginal land and seen its influence to growth of seed of suren. Research has been done in green house at Faculty Of Agriculture of USU on March-May 2012 using completely randomized factorial design of two factors that is concentration of humic acid ( 0%, 2.5% and 5%) and dose prular NPK fertilizer ( 0 gr; 1 gr; 2 gr; 3 gr and 4 gr per crop). The parameters observed were height of the plant, diameter of stem, dry wight, wide total of leaf and ratio of root crown. The results of research indicate that the concentration of humic acid do not have an effect on the reality to all of the parameters except to parameter of ratio of root crown. But dosage of NPK fertilizer have significantly effect to all of the parameters. The combination of the concentration of humic acid and NPK fertilizer do not have an effect on the reality to all parameter. All of the dose of NPK fertilizer besides control have a different significantly to the growth of the plant. Thereby, using of NPK fertilizer is good to growth of plant on marginal land media. Keyword : marginal land, humic acid, NPK fertilizer, seed of suren.

Community Service Program in agroforestry land management together with the people of Candi Rejo of Village, Biru- Biru Sub-District, Deli Serdang, North Sumatra, aims to assist the community in managing agroforestry land to improve community skills in managing their agroforestry land. Some of the activities carried out are making compost using cocoa waste and animal husbandry, prunning cocoa plants to reduce pest and disease attacks and planting mindi, avocado, durian species for enrichment of species on agroforestry land. Based on the result of interviews with farmers that the use of compost is more effective in increasing cocoa production.

Abstract The aim of this research was to improve the quality of liquid waste water by looked at the role of test plants (warter hyacinth, water jasmine and apu wood)by phytoremediation process in reducing pollutant level. This research was conducted at Rumah Kaca Faculty of Agriculture University of Sumatera Utara Medan from July 2016 to April 2017.This research was used factorial randomized block design with two factors. The first factor was tofu waste with three levels; L0 (no waste) as control , L1(25%) and L2 (50%). The second factor was plant species with four levels were T0 (no plant as control), T1 (water hyacinth), T2 (jasmine water) and T3 (apu wood). The parameters observed were BOD (mg / L), COD (mg / L), TSS (mg / L), NH3N (mg / L), pH, waste colours, odor waste and dry weight of plans (grams).The results showed that the three test plants could be used for phytoremediation process, tofu waste, 25% waste concentration as the best apu wood in reducing the pollutant level of tofu waste.Keywords: tofu liquid waste, aquatic plants, phytoremediation, contaminants

Desa Bagan Kuala di Serdang Bedagai memiliki banyak potensi ekowisata salah satunya adalah ekosistem mangrove. Namun pemanfaatan sumber daya alam secara berkelanjutan belum diterapkan dengan baik. Tujuan dari kegiatan ini adalah untuk meningkatkan kapasitas peserta dalam pemanfaatan tanaman mangrove sebagai pewarna alami dan praktik ecoprint. Dalam upaya untuk meningkatkan kapasitas dan memperkuat ekonomi lokal, workshop ini melibatkan pelatihan teknik ecoprint menggunakan pewarna yang berasal dari ekstrak mangrove, yang tidak hanya ramah lingkungan tetapi juga memiliki nilai jual yang cukup tinggi. Hasil pewarnaan kain memiliki variasi warna dan motif. Keterlibatan masyarakat dalam workshop ini juga dapat meningkatkan kesadaran akan pentingnya menjaga ekosistem mangrove dan membuka peluang bisnis baru untuk mendukung ekowisata di daerah tersebut. Pengetahuan peserta terkait zat warna alam (ZWA) mengalami peningkatan dari 20% menjadi 100% peserta yang tahu tentang ZWA. Pengetahun peserta terhadap manfaat mangrove untuk batik yang awalnya hanya 6% meningkat menjadi 80%. Pengetahuan bahwa mangrove dapat dibuat untuk pewarnaan kain yang bukan batik juga mengalami peningkatan dari yang awalnya hanya 6% meningkat menjadi 87%. Pengetahun tentang ecoprint juga mengalami peningkatan pesat yang awalnya hanya 6% menjadi 100%. Diharapkan bahwa program ini akan menjadi langkah awal dalam menggabungkan pengembangan ekonomi berbasis masyarakat dengan pengelolaan lingkungan

This method is also a solution for cultivators to cultivate fish without damaging the mangrove ecosystem. It is hoped that the results of this service activity can be used as a model or input for the community in order to manage ponds with silvofishery technology without having to do open ponds which will slowly damage the environment. This community service activity aimed to provide information and skills to partner groups on the silvofishery method. Other aim was to assist partners in the tilapia rearing process. Based on the description of the problems and objectives of this community service activity, the activities that have been carried out are counseling about silvofishery. The second activity, provision of tilapia seeds and feed for fish rearing activities in silvofishery ponds. The results obtained were increased partners' knowledge and skills regarding silvofishery. The people of Tanjungrejo Village also get tilapia cultivation products that can be traded without cutting down mangrove trees.
