Abstract

The objectives of this study was to assess the farming system of organic lowland paddy to soil pollution compared with conventional farming system in Deli Serdang Regency. An environmental assesment in this research as limited to the soil pollution caused by pesticides and chemical fertilizers. Soil samples were grouped into low and upper layers. Each soil composites was collected from ten sampling points. Which each consist of 5 sampling points of organic paddy farming system and 5 sampling points of conventional paddy farming  system. The results showed that the levels of pesticides and nitrate in paddy soil was influenced by soil layers, meanwhile although was not statistically significant, the levels of pesticides and nitrate increased due to the way of cultivation.The results indicated that in general the soil pollution on organic paddy farming system was lower than conventional farming. Levels of pesticides and nitrate in the soil layer 20-40 cm was higher than levels of pesticides in the 0-20 cm. Pesticides and nitrate leached by water gets into the deeper layers of soil. The increased level of pesticides in soil of conventional farming was higher 0.96 ppm during the dry season and lowest 0.38 ppm in the rainy season compared with organic farming. The increased level of nitrate in soil of conventional farming was higher 0.45 ppm during the rainy season compared with organic farming, however in the dry season, the level of nitrate in conventional farming was lowest 2.32 ppm compared with organic farming.Keywords: conventional farming; organic farming; paddy; sustainability

Abstract

Preliminary studies in Screening of Potato (Solanum tuberosum L.) as a result of drought stress (in vitro). This study aim was to determine the limits of potato (Solanum tuberosum L.) to drought stress conditions in vitro using PEG. This research was conducted at the Tissue Culture Laboratory Unit / Laboratorium Kultur Jaringan UPT/Balai Benih Induk Hortikultura Dinas Pertanian Propinsi Sumatera Utara, Jl. Karya Jasa No. 6 Gedung Johor Medan in March 2012 to June 2012. The Completely Randomized Design (non factorial) was used with PEG concentrations of five levels, namely: P1 = 10%, P2 = 20%, P3= 30%, P4 = 40% and P5 = 50% with 5 replications. The results showed that increasing the concentration of PEG will reduce the percentage of plantlets survival, reduce plant height, number of roots and number of nodes. Treatment of 50% PEG resulted in the death of potato cuttings due to drought stress.

Abstract

The purpose of this research is to determine the effect of mycorrhizal inoculation and volcanic ash as composting material on growth and yield of chilli. The materials used were mycorrhizal inoculant, chilli seeds of local varieties, cow feces, volcanic ash, EM4, and molasses. This research was conducted in the village Payung, District of Tanah Karo, North Sumatera Province, started from May to September 2015. The research consists of several steps, those were the producing of the compost, analysis of chemical composition, and biological test by cultivating chilli seeds using inoculating micorrhizal and compost of volcanic ash. Observed physical parameters were temperature and pH during the composting process. Observed chemistry parameters were including: organic carbon (C), nitrogen(N), phosphorus (P2O5), potassium (K2O), and C/N ratio. Biological parameters were the plant height, the number of branches, total fruit yield, wet weight root, and root dry weight. Design of the experiment was used factorial randomized block design consisting of two factors and three replications namely providing mycorrhizal consiststed of 3 levels ; without any mycorrhizal, with mycorrhizal 3, 5 and 7 g / plant, and compost of volcanic ash consists of 3 levels ; without any compost of volcanic ash, 1, 2 and 3 kg/bed. The data were analyzed with analysis of variance α = 5%, continued by Duncan's Multiple Range Test α = 5%. The result showed that using of volcanic ash as composting matter gave no effect on composting process. Based on the results chemical analysis of the soil showed improved soil fertility (C: 4,25%; N: 1.83%; P: 1.06 ppm; K: 0.35%,C/N : 2,32% and pH: 7.2). Biological test showed that mycorrhizal inoculation 7 g/plant give a real contribution to increase the plant height, the number of branches, total fruit yield, wet weight root, root dry weight. The compost of volcanic ash up to 3 kg / bed show no significant difference on the growth and yield of chilli peppers.

Abstract

Desa Ujung Bawang merupakan salah satu desa sentra tanaman cabai, berhubung potensi agroklimatnya yang mendukung pertumbuhan dan produksitanaman. Namun, selama beberapa tahun belakangan Desa ini mengalami kemarau yang berkepanjangan. Hal ini menjadi masalah besar bagi petanicabai yang hanya mengandalkan air hujan untuk pengairan, sehingga terjadi gagal panen cabai. Petani juga kesulitan memperoleh pupuk subsidi dari pemerintah karena terbatasnya persediaan, dan di pasaran pupuk langka serta harganya mahal. Melalui program kemitraan dengan petani, telah dilakukan penerapan teknologi dengan metode irigasi tetes dari sumber mata air yang berada dekat lahan petanikemudian mengalirkannya ke lahan dengan sistem kontrol. Selanjutnya dilakukan pelatihan pengolahan limbah kulit ceri kopi menjadi kompos. Kegiatan ini memberikan dampak positif kepada petani mitra, yaitu: petani tidak kesulitan lagi untuk mengairi tanamannya; petanitidak tergantung pada pupuk subsidi maupun pupuk yang dibeli dari luar; dan peningkatan pengetahuan dan keterampilan tentang pengolahan limbah menjadi kompos. Kompos yang dihasilkan memenuhi beberapa kriteria SNI 19-7030-2004. Penelitian menunjukkan bahwa penerapan teknologi memberikan penurunan biaya produksi sebesar 39,05% dan peningkatan pendapatan sebesar 12,4% dari petani yang belum memanfaatkan teknologi. Walaupun produksi yang diperoleh lebih rendah dari petani yang belum memanfaatkan teknologi (2,93%), hal ini disebabkan lahan baru pertama sekali ditanam cabai. Kata kunci: Cabai, Irigasi tetes, Limbah, Kompos ABSTRACT Ujung Bawang Village is one of the centers of chili plantation due to its agro-climate that supports growth and production. However, these past years the village experienced prolonged dry season. This became a problem with chili farmers that depended only on rainwater, which caused production decline. Aside from that, farmers also experienced difficulties acquiring subsidized fertilizer from the government due to supply limit and lack of stock or unaffordable prices in stores. Through partnership program, we’ve applied a technology with drip irrigation method from water source near the land with control. Training to process coffee cherries waste to become compost was also done. These resulted in positive impacts to farmers, which are: (1) no difficulty to irrigate plants; (2) not dependant on subsidized or purchased fertilizer anymore; (3) knowledge and skill advancement to process waste into compost. The compost produced passed some of SNI 19-7030-2004 criteria. Research shows these reduce production cost as much as 39,05% and increase income to 12,4% more than farmers who haven’t applied the technology. Although production rate was lower than farmers who haven’t applied it (2,93%), this is due to soil’s first time being planted with chili. Keywords: Chili, Drip irrigation, Waste, Compost

Abstract

Jagung (Zea mays L.) merupakan salah satu tanaman pangan dunia yang terpenting, selain gandum dan padi. Lahan yang berpotensi sebagai lahan untuk produksi jagung diantaranya adalah lahan kering marginal. Lahan kering marginal adalah lahan yang tingkat kesuburannya rendah. Salah satu usaha yang dapat dilaksanakan untuk meningkatkan kesuburan tanah adalah melalui bioteknologi biofertiliser yaitu inokulasi mikoriza dan pemberian pupuk kompos. Penelitian dilakukan di lahan Fakultas Pertanian Universitas Metodist Indonesia. Percobaan menggunakan Rancangan Acak Kelompok (RAK) yang terdiri atas sembilan kombinasi perlakuan inokulasi mikoriza dan pupuk kompos dengan tiga ulangan. Perlakuan tersebut terdiri atas: M0 (tanpa inokulan mikoriza); M1 (inokulan 5 g tanaman-1); M2 (inokulan 10 g tanaman-1) dan O0 (tanpa pupuk kompos); O1 (50 g pupuk kompos tanaman-1); O2 (100 g pupuk kompos tanaman-1). Hasil penelitian menunjukkan bahwa inokulasi mikoriza sebesar 10 g tanaman-1 dan pupuk kompos sebesar 100 g tanaman-1 memberikan kontribusi yang nyata terhadap pertumbuhan tanaman jagung meliputi tinggi tanaman dan diameter batang, sedangkan inokulasi mikoriza sebesar 10 g tanaman-1 dan dosis pupuk kompos sebesar 50 g tanaman-1 dapat meningkatkan serapan P oleh tanaman jagung. Dengan demikian dapat disimpulkan bahwa kontribusi pemberian mikoriza dan pupuk kompos dapat meningkatkan kesuburan tanah lahan kering marginal ditandai dengan memacu pertumbuhan tanaman jagung dengan cara meningkatkan P-tersedia dan mengefektifkan penyerapan P sehingga penggunaan pupuk P dapat lebih efisien.

Abstract

Karang Bangun Village is one of the centers for lowland rice production in Simalungun Regency, North Sumatra. The area of rice fields reaches 70% of the village area with good technical irrigation. However, the application of technology in the management of lowland rice in this village is still very conventional, and the knowledge of farmers about the new technology does not yet exist so that production only reaches 6 tons/ha. The purpose of this community service activity is to transfer the rice cultivation technology which is effective in increasing yields. The technologies are the application of the System of Rice Intensification (S.R.I) method, processing of straw waste into Bokashi organic fertilizer which can increase soil fertility, recognition of the symptoms of plant nutrient deficiency, and the use of plants as natural pesticides. Through assistance to farmers using a participatory approach in community service activities, the transfer of technology can run smoothly so that the use of irrigation water can be efficient, efficiently in using inorganic fertilizers, the use of inorganic pesticides is reduced and the productivity of farmers' land can be increased and by itself will improve the welfare of farmer.

Abstract

ABSTRAKGas metana (CH4) adalah salah satu gas rumah kaca yang cukup berperan setelah CO2. Peningkatan metana di atmosfer pada belakangan ini perlu diantisipasi mengingat daya pemanasan global yang ditimbulkannya per satu molekul gas metana di troposfer 21 kali lebih tinggi daripada daya pemanasan satu molekul CO2. Tanah sawah adalah salah satu kontributor gas metana sekitar 10-15%. Metana diproduksi sebagai hasil akhir dari proses dekomposisi mikrobial bahan organik secara anaerobik oleh bakteri metanogen. Emisi gas metana ditentukan oleh pengelolaan air, pengolahan tanah, varietas, dan iklim. Seiring dengan kesadaran masyarakat terhadap produk pangan yang sehat, serta ramah lingkungan, maka permintaan akan beras organik meningkat, sehingga perlu diupayakan dengan giat intensifikasi maupun ekstensifikasi budidaya padi organik. Namun, budidaya padi organik menghadapi dilema yaitu peningkatan produksi gas metana lebih tinggi daripada budidaya padi konvensional.ABSTRACTMethane (CH4) is the second main type of gas after CO2 in contributing global warning. The increasing of methane in our atmosphere should be anticipated because its effect of single molecule of methane to the warning up our trophosphere is 21 times higher than single molecule of CO2 . Paddy field soils as one of contributors produce 10-15 % of methane in our atmosphere. The methane is produced as results of microbial processes on aerobic organic matters decomposition by metanogene bacteria. The amount of methane production is determined by soil water management, crop species, and climate. In line with the community awarness in healthy and environmental friendly product of food, the demand of organic rice has increased. However, the organic farming has trade off situation due to its methane production higher than the conventional farming.
