Judul: Performance of Mother Plant, Seedling, and Nursery Transplant on Several Accession Fig (Ficus carica L.)
Abstrak: Tin (Ficus carica L.) merupakan tanaman famili Moracea dari daerah beriklim subtropis. Tanaman tin dapat dibudidayakan secara vegetatif melalui setek batang. Tanaman tin dari setiap negara memiliki perbedaan karakteristik, namun sayangnya masih sedikit penelitian mengenai ragam jenis tanaman tin. Penelitian mengenai media tanam yang tepat dalam budidaya tin juga masih sulit ditemukan, oleh karena itu penelitian terkait respon pertumbuhan aksesi tin pada tahapan budidaya dengan percobaan berbagai media tanam ini perlu dilakukan. Penelitian ini terbagi menjadi tiga bagian, yaitu penelitian pada tanaman induk, hasil persemaian dan pembibitan. Tanaman induk dan pembibitan menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) faktor tunggal, yaitu aksesi. Persemaian menggunakan RKLT split plot dengan perlakuan media tanam dan aksesi. Hasil analisis ragam menunjukkan bahwa tidak ada keragaman pada peubah panjang cabang, jumlah daun, dan panjang buah pada tanaman induk. Hasil analisis ragam pada persemaian menghasilkan interaksi antara media tanam dan aksesi yang berpengaruh sangat nyata pada peubah jumlah tunas, panjang tunas, dan jumlah daun. Aksesi LSU Gold dan Red Yerussalem lebih baik di tanam pada media campuran arang sekam dan tanah, sedangkan aksesi Brown Turkey lebih baik di tanam pada media dengan komposisi tanah, sekam bakar, bakteri penyubur, dan pupuk kandang kambing. Aksesi Sals Corleone, Big Giant dan JH Adriatic menghasilkan pertumbuhan yang sama baiknya pada kedua media tanam. Persentase tumbuh tertinggi pada media campuran arang sekam dan tanah saat 6 MSS ialah aksesi Red Yerussalem (70%), sedangkan persentase tumbuh tertinggi pada media dengan komposisi tanah, sekam bakar, bakteri penyubur, dan pupuk kandang kambing ialah aksesi Big Giant (70%). Tidak ada keragaman yang nyata dalam panjang tunas pada pembibitan. Kata kunci: aksesi, media tanam, setek, tin, Fig (Ficus carica L.) is a Moracea family plant native to subtropical climates. Fig can be propagated with vegetative method through stem cuttings. Fig plants from each country have different characteristics, unfortunately there are not many research about fig plants varieties. Research on the suitable planting media in fig cultivation is also difficult to find, therefore research that related to growth response of fig accession at the stage of cultivation with the experiment of various planting media need to be done. This research is divided into three parts, namely mother plant, seedbed, and nurseries. Mother plant and nurseries used a single factor Randomized Complete Group Design (RKLT), namely accession. The nursery used a split plot RKLT with the planting media and accession treatment. The results of the variety analysis showed that there was no variation in the variables of branch length, number of foliages, and fruit length on the mother plant. The results of the variety analysis on seedbed showed that the interaction between planting media and accession had a real effect on the variable number of shoots, the length of shoots, and the variable number of foliages. LSU Gold and Red Yerussalem accession were better planted on the mixed media of charcoal husks and soil, while Brown Turkey accession is better on the planting media with composition soil, chaff, fertilizing bacteria, and goat manure. Sals Corleone, Big Giant, and JH Adriatic accession generate similar growth on both planting media. The highest growth

Judul: Pengaruh Komposisi Media Tanam Terhadap Pertumbuhan Stek Batang Tanaman Ara (Ficus carica L).
Abstrak: The aimed of this study was to find the best plant media for the growth of fig cuttings. The experiment was conducted in July to October 2012 at Leuwikopo Experimental Farm, Bogor Agricultural University, Indonesia. The experiment was arranged in Randomized Complete Block Design with plant media compotition as the treatment and four replications. The plant media consisted of soil, rice hull charcoal, and goat manure (2:1:1); soil, bamboo leaves compost and rice hull charcoal (2:1:1); cocopeat and bamboo leaves compost (1:1);rice hull charcoal, goat manure and bamboo leaves compost (1:1:1). The result showed that the plant consisted of soil, rice hull charcoal, and goat manure; soil, bamboo leaves compost and rice hull charcoal; and rice hull charcoal, goat manure and bamboo leaves compost gave the same performance in fig cuttings of life percentages, that were 65.5, 70.0 and 65.0%, whereas plant media consisted of cocopeat and bamboo leaves compost gave the lowest result of 37.5%.

Abstrak: The solution of Schrodinger equations with plasma Coulomb potential in spherical coordinat results solution wave function and energy plasma particle. Electron probability density at Debye length with thermal effect same as ion, which indicates plasma in neutral state. Electromagnetic waves perturbation of an electric field given to result wave function perturbation system. The probability density of plasma particle due to electromagnetic waves perturbation is the largest when an electromagnetic waves frequency 1.41 times the plasma frequency .
