Published: December 2019

The research objectives were to find out the growth responses and the results of providing water treatment and manure from buffaloes to C/N which is different from the rice plant variety. The rice was planted in a pot arranged in a greenhouse. The water treatment consisted of two treatment phases, namely irrigation with interval and continuous irrigation. The provision of manure from buffaloes consisted of without treatment, with treatment of C/N 19, 80:1 and treatment of C/N 10, 15:1. The varieties studied were Inpari 1, Inpari 13, Siramos and Siboru Tambun. The results showed that water treatment had positive influence on the plant development which was significantly seen in the height of plant and the number of plantlet and panicle. The best irrigation was indicated by the irrigation with interval. The provision of manure from buffaloes had influence on the number of plantlet per cluster which was indicated very significantly by 40 HST, significantly by 20HST, and very significantly by 40 and 60 HST; and on the number of panicle per cluster which was indicated significantly by 60 HST and very significantly by 100 HST filled grains, and on the number of empty grains per cluster, indicating positive influence.

The growth of the rubber depends on some factors in the nursery. One of critical point was on stumping fase. After stumping fase, the number of death plants is quite high at young budding of seedling. This research used Factorial Radomized Complete Block Design (RCBD) with two factors and three replications. The Height of rootstock stumped (10, 20 and 30 cm) and the concentration of BAP (15, 30, 45 and 60 mg / 200 g Lanolin). Results of the research showed the number of life budding shoots significantly affect the interaction of stumping and BAP. The results showed that rootstock stumped 30 cm and BAP 60 g / 200 g Lanolin is the best treatment for height of budding shoots (410.67 mm) and the percentage of life budding shoots (66.67%).

Autopot an irrigation device which is operated automatically and is capable of providing nutrition in plants without the need for electrical energy. The system is operated via a smart valve that is used to open and close automatically irrigation water by the water conditions in the network system, especially the water level in the network. Basic water level is used as a mechanical sensor for opening and closing the valve automatically without the aid of another power. With these advantages, autopot able to provide water and energy efficiency is very high on a commercial scale hydroponic cultivation. It's just that the system requires very high investment and must be imported. Therefore, this study was conducted to modify the Autopot use of materials and simple equipment and test its performance on the cultivation of red lettuce. Autopot modifications performed on tools, growing media and fertigation systems are smart valve replacement valves using a hole in the bottle that works with pressure and gravity. This study aims to determine the performance test auto pot modification results in the cultivation of red lettuce as well as to determine the ratio of planting media best on auto pot system modifications. Research carried out for 90 days in a greenhouse using descriptive methods. The results showed Autopot Modifications have an average efficiency of the provision of water by 75.86% - 88.05% and an average efficiency of water use by 51.43 kg / m3-88.72 kg / m3, this efficiency is high because of high dihasikan crop production with the use of water low. Planting media between rice husk and humus in the ratio of 50:50 compositions show results better plant growth compared with other growing media composition. plants with irrigation efficiency levels are very high as well minus the electric energy consumption.

This research was conducted at the greenhouse Faculty of the Agriculture University of Sumatera Utara, Medan from March to April 2017. The research used Randomized Block Design (RBD) with two using two factors i.e : F1 population (NEI 9008 x CLA 46, CLA 84 x NEI 9008, CLA 106 x NEI 9008, CLA 16 x CLA 84, and CLA 84 x P1027) and iron stress treatment (0, 50 ppm, and 100 ppm). The results showed that the F1 population had a significant effect on root-canopy weight, root volume, and root canopy ratio. Iron stress treatment with different concentrations had a significant effect on root distribution parameters, root canopy ratio, root length, and the extension of root length. The interaction between F1 population and iron stress has a significant effect on root volume character. Iron treatment with a concentration of 100 ppm can still be tolerated by the F1 population of maize crops on nutrient culture. The CLA 16 x CLA 84 populations had a better adaptation to the iron stress treatment in nutrient culture media. The CLA 16 x CLA 84 had lower stress sensitivity index value and a smaller productivity gap on root dry weight.

Penelitian ini menggunakan rancangan acak lengkap dua faktor dengan 3 ulangan. Faktor pertama pemberian dosis pupuk (Urea, SP-36, KCl, dan Dolomit) dengan 4 taraf yaitu P1 = 121,36 gram/Plot, P2 = 161,82 gram/Plot, P3 = 202,27 gram/Plot,P4 = 242,73 gram/Plot, dan faktor kedua berdasarkan indeks hara tanah dengan 5 taraf yaitu B1 = 0,8 (dosis pupuk dikurang 20%), B2 = 0,9 (dosis pupuk dikurang 10%), B3 = 1 (100% indeks hara standar), B4 = 1,1 (dosis pupuk ditambah 10%), B5 = 1,2 (dosis pupuk ditambah 20%). Hasil penelitian menunjukan bahwa pemberian pupuk berdasarkan target produksi 15 ton/ha (242,73 gram/Plot) nyata meningkatkan tinggi tanaman dan jumlah anakan. Indeks hara tertinggi ialah indeks hara 0,9 (dosis dikurang 10%) yang artinya tanah mempu memberikan unsur hara sebanyak 10% untuk perkembangan padi (jumlah malai dan panjang malai).

Negara Indonesia menduduki peringkat ketiga di dunia sebagai penghasil kakao (Theobroma cacao L) setelah Pantai Gading dan Ghana. Kakao sebagai komoditas eksport dihasilkan dari Sumatera Barat, Aceh, Lampung, Sulawesi Barat, Sulawesi Tengah, Sulawesi Tenggara, dan juga Nusa Tenggara Timur. Buah kakao merupakan komoditas unggulan, tetapi mengalami penurunan kualitas karena adanya serangan penyakit yang disebabkan oleh jamur Phytophtora palmivora. Penyakit ini kasat mata timbul warna putih berkebul dan menimbulkan bercak hitam hampir seluruh permukaan buah kakao dan bila disentuh akan terasa basah membusuk. Untuk itu perlu solusi yang tepat dan ramah lingkungan yaitu menggunakan agen biologi hayati sebagai biofungisida. Peran antagonisme yang dapat digunakan sebagai biofungisida untuk pengendali busuk buah kakao adalah Trichoderma virens. Sifat antagonisme dapat menyerang cendawan lain, dikarenakan T. virens menghasilkan senyawa viridiol phytotoxins dan gliotoxin untuk menjadi parasit bagi P. palmivora.

Penyakit antraknosa (Colletotrichum spp.) dapat menyebabkan rendahnya kuantitas maupun kualitas buah yang dihasilkan. Untuk menghindari penggunaan pestisida sintetik maka diperlukan alternatif pengendalian yang bersifat ramah lingkungan, diantaranya kitosan sebagai agen penghambat penyakit antraknosa. Tujuan penelitian ini adalah menguji efektifitas formula nano kitosan untuk mengendalikan penyakit antraknosa melalui pengujian in vivo pada tanaman cabai cv. Tanjung di lapangan. Penelitian dilaksanakan di KP Pacet Cianjur, Jawa Barat sejak bulan Mei sampai September 2017, menggunakan RAK terdiri dari 6 perlakuan dan 5 ulangan. Kitosan-tripolifosfat (K-TPP) nanopartikel dilarutkan dalam air dan diaplikasikan pada tanaman cabai dengan konsentrasi 0,5 – 2 mL/L. Aplikasi penyemprotan formula dilakukan saat tanaman berumur 30 – 65 hari setelah tanam menggunakan alat semprot punggung. Kitosan cenderung menghambat infeksi fungi Colletotrichum spp. pada cabai. Pada pengamatan ke-5, penghambatan kitosan terhadap buah cabai terinfeksi antraknosa masing-masing berkisar dengan intensitas serangan. 0,41 sampai 2,41%. Hasil penelitian menunjukkan K-TPP pada konsentrasi 0,5 – 1,0 mL/L cukup efektif menekan penyakit antraknosa pada buah cabai, dengan daya hambat >50% dibanding perlakuan kontrol (tanpa K-TPP). Hasil penelitian mengindikasikan bahwa kitosan bisa diaplikasikan untuk memperlambat laju infeksi penyakit antraknosa pada buah cabai, dan penelitian lanjutan masih diperlukan untuk menguji di lokasi lainnya serta musim yang berbeda.
