Abstract

The study aims to know the efectivity of sterilization and the efficiency of Morashige Skoog media on the growth of Aloe vera L. explant, has been done in tissue culture laboratory, Faculty of Agriculture Sarjanawiyata Tamansiswa University. The experiment is factorial 4 x 3, arranged in a Completely Randomized Design with three replication. The first factor was sterilization methode (S) consist of four levels, those are: sterilization methode 1 (S 1), methode 2 (S2), methode 3 (S3), and methode 4 (S4). The second factor was concentration of MS media consist of three levels those are : full media (M1), ½ media (M2), and ¼ media (M3). The variables observed were : date of shoot emerge, number and height of shoots, number of leaves and roots, root length, shoot and root fresh weight, shoot – root dry weight and viability potensial of the explant. The result of analysis uses analysis of varians on the significant level 5%, and continued with Duncan’s Multiple Range Test significant level 5%. The conclution of experiment are interaction between sterilization 3, 4 methode, and full and ½ media concentration on viability of explant variable observed. The better of explant growth was gained the efectivity on alcohol of 96% and hyphocloric of 50% as long as 3 minutes sterilization methode, likewise the better of explant growth was gained the efficiency on ½ consentration MS media treatment.

Abstract

A complete content of chemical substance from Aloe vera leaf makes this plant has many functions such as the ingredient of functional food for health, cosmetics, and herbal medicines. This research was aimed to determine the yield and quality of Aloe vera L. on various types and rates of green mulch in coastal sandy soil. The research was conducted in coastal sandy soil of Poncosari Srandakan, Bantul, Yogyakarta and done in a Randomized Complete Block Design (RCBD) of two factors with three replications. The first factor was four types of green mulch (shrimp evergreen, cashew, acasia and gliricidia). The second factor was various rate of green mulch consisted of three levels rates of leave mulch (5.0, 10.0, and 15.0 tons ha-1). Soil without mulching was used as a control treatment. The variables observed were yield at the first harvest time and leaf content quality which includes water, protein, fat, carbohydrate, ash, fiber, and mineral (Ca, Fe and Zn). The results showed that there was interaction between types and rates of leave mulch in all variables observed. Gliricidia leaf mulch gave the best effect with optimum rate about of 10 ton ha-1. The effectiveness of green mulch abilities on improving the observed variables from higher order to low was gliricidia, acasia, cashew and shrimp-type evergreen with the rate range between 10 up to 15 tons ha-1.

Abstract

Penelitian bertujuan untuk mengetahui jenis, populasi, frequensi, dan dominansi tanaman lidah buaya telah dilaksanakan di D. I. Yogyakarta, mulai bulan Maret hingga September 2012. Penelitian menggunakan metode analisis vegetasi, survei lokasi, dan pengambilan sampel tanaman dari lokasi kalurahan, kecamatan dalam kabupaten di wilayah Provinsi D. I. Yogyakarta. Untuk mengetahui jenis tanaman menggunakan metode deskripsi dengan kunci identifikasi metode dichotomi.Variabel pengamatan meliputi jenis tanaman, frequensi, dan dominansi tanaman. Analisis sidik ragam jenjang nyata lima persen, untuk mengetahui beda nyata antarkabupaten atau kecamatan. Hasil penelitian menunjukkan bahwa di D. I. Yogyakarta  ditemukan tiga jenis tanaman, yaitu: Aloe ferox Mill, Aloe vera (chinensis) L. dan Aloe barbadensis. Populasi tertinggi, baik di kabupaten atau provinsi Aloe vera (chinensis) L., populasi terendah adalah Aloe barbedensis. Frequensi jenis Aloe vera L dan Aloe ferox mill sama, yaitu 100 persen, sedangkan Aloe barbadensis paling rendah, yaitu 80 persen. Dominansi tertinggi dari jenis Aloe vera L. The study aims to determine the types, population, frequency and dominance Aloe sp. plant has been conducted in Yogyakarta, from March up to September 2012. Research carried out by the method of vegetation analysis through surveys and sampling of the Aloe sp. plant locations, districts in the regency and in the province Special Region of Yogyakarta. To determine the types of Aloe sp. plants using descriptions that are tailored to the identification of key observations dichotomi.The variable include types of plant, frequency distribution of plant, and plant dominance. Analysis of variance real level of five percent, in order to know the real difference between the district or sub-district results showed that in Yogyakarta found three (3) types of plants are: Aloe ferox Mill, Aloe vera L. and Aloe barbadensis. Highest population in both counties is Aloe vera and province. While the lowest population is Aloe barbadensis. Frequency spread between the types of Aloe vera L.and Aloe ferox Mill equal 100 percent, while frequency spread of Aloe barbadensis least 80 percent. The highest dominance is Aloe vera L. type.

Abstract

The research aims to study of growth and yield jack bean (Canavalia ensiformis L.) as the substitution of soybean plants on the application of different inoculants and doses of urea fertilizer, has been carried out in Depok, Kretek, Bantul Special Region of Yogyakarta. The research was a factorial experiment arranged in Randomized Completly Block Design with four replications. The first factor was kind of inoculants, consists of two kinds: peanut and soybean Rhizobium inoculants, the second factor was doses of urea fertilizer consisted of three levels 25; 50 and 75 kg per ha. Observation variables include the number of root nodules, height of plant, fresh and dry weight of plants aged 6 and 10 weeks, the number and weight of pods, weight of seeds per plot, the index growth, absolute growth rate, harvest index and yield per hectare. Data were analyzed by analysis of variance followed by Duncan?s Multiple Range Test of 5 % significant level. Conclusion there was no interaction between kind of inoculants and doses of urea fertilizer of all variables. Inoculants do not enhance the growth and yield of jack bean, while the urea fertilizer of 75 kg urea per hectare improving growth and yield jack bean increase amounted to 42.64% of the application fertilizer urea 50 kg per ha.?Keywords : Growth, Rhizobium inoculant, jackbean, urea fertilizer, yield.

Variabel pengamatan meliputi analisis pertumbuhan dan hasil umbi per ha. Analisis data menggunakan sidik ragam taraf lima persen, dilanjutkan Uji Jarak Berganda Duncan ? 5%. Kesimpulan: tidak terjadi interaksi dosis pupuk ZA dengan sumber rhizobacteria terhadap semua variabel pengamatan. Dosis ZA sampai 350 kg per ha  tidak meningkatkan pertumbuhan, sedangkan hasil umbi tertinggi diperoleh pada dosis 250 kg, lebih tinggi daripada kontrol. Sumber rhizobacteria gamal memberikan pertumbuhan terbaik, hasil tertinggi diperoleh pada pemberian rhizobacteria bambu.
