This research was conducted at the Greenhouse Laboratory of the Faculty of Agriculture, Sebelas Maret University Surakarta, in March 2011. The aim of the study was to determine the relationship between the rainfall (synthetic) the number of elements Potassium (K) and Sodium (Na) were leached in volcanic material from the eruption of Mount Merapi. This study used artificial rainfall simulation approach to treatment is based on the phenomenon of the eruption of Mount Merapi, Yogyakarta, Central Java by examining the leaching elements Sodium (Na) and Potassium (K) are swapped in the above-ground volcanic material Andisol. The experiments in this study using a completely randomized design (CRD) consisting of 3 to 5 treatments the sample depth artificial rain (water sprinkling) in 3 replications, namely 1 (22 mm x 1 day (22 mm)), 2 (22 mm x 10 days (220 mm)), 3 (22 mm x 20 days (440 mm)), 4 (22 mm x 30 days (660 mm)), 5 (22 mm x 45 days (990 mm)), and control ( 45 days field) with 3 replicates each. The variables measured were pH H2O, available K and Na, K and Na total, CEC, texture. Analysis of the data using the F test at the level of 95% or Kruskal-Wallis, to compare the mean between treatments using DMR test at the level of 95% or Mood Median, whereas to determine the relationship between variables used correlation test. The results showed that administration of rainfall of 22 mm / day is able to affect the leaching of potassium and sodium in the volcanic material from day 10. Leaching was significantly visible on day 30 with a decrease in available K and Na volcanic material at a depth of 0-15 cm in diameter (K 23.08%) (23.08% Na) and at a depth of 15-30 cm (K 21, 42%) (23.08% Na), and the addition of K and Na are available at a depth of >30 cm in the form of land Andisol (K 16.67%) (23.53% Na) from the previous treatment.

Utilization of farm wastes in order to realize the concept of integrated farming is a sustainable agriculture community service program in cooperation with two partners, namely : ( 1 ) quail - catfish Breeders 'Agribird', and ( 2 ) dairy farms and agricultural businesses " Andini Mulyo ". This service activities conducted through outreach / awareness, mentoring and manufacture of demonstration plots. Preparation of demonstration plots to make an example of earthworm cultivation ( vermikultur ) and the making of silage. Testing vermicompost and organic fertilizer from cow dung to plant corn and kale using plots measuring 50 x 9 meters, divided into 3 blocks, each 3 x 50 meters. Outcome in the form of products include : Biomass earthworm number 5 Kg / month ; Vermicompost 50 Kg ; Silage, 300 Kg once manufacture ; and quality organic fertilizer from cow dung, 600 kg / process. Outcome in the form of a test product to the plant : the use of manure, vermicompost fertilizer in Litosol very real increase maize crop which includes fresh weight of corn stover, corn stover dry weight and dry weight of seed corn ; the use of manure and fertilizer plants in the ground grumosol not significantly different with kale stover fresh weight, while the use of vermicompost highly significant increase stover fresh weight of spinach.

Perbaikan genetik melalui persilangan interspesifik antara tetua terpilih anggrek Dendrobium spp diarahkan untuk meningkatkan mutu genetik dan nilai ekonomi anggrek alam dipasaran. Anggrek Dendrobium adalah salah satu genus anggrek yang banyak diminati. Upaya peningkatan mutu genetik anggrek memiliki kendala pada teknik penyilangan dan perbanyakan biji hasil hibridisasi/persilangan. Penelitian bertujuan untuk: (1) mendapatkan teknik penyilangan yang dapat menghasilkan biji dengan tingkat fertilitas tinggi dan (2) mendapatkan anggrek hibrida baru yang memiliki keunggulankeunggulan karakter. Penelitian dilakukan di Pusat Konservasi Tumbuhan Kebon Raya LIPI Bogor. Persilangan dilakukan pada 4 sampai 6 individu yang berbunga. Persilangan dilakukan dengan cara menyilangkan tetua terpilih sebagai tetua jantan atau betina Pollinia ditransfer dari anther ke stigma dengan menggunakan tusuk gigi steril, dengan metode (i) crossing , (ii) Resiprocal.Pengamatan dilakukan terhadap karakter induk yang digunakan, waktu persilangan sampai dengan panen buah, dan lama berkecambah. Dari penelitian dihasilkan 4 seri silangan secara resiprok sampai perkecambahan yaitu ♀ Dendrobium mirbelianum x ♂ Dendrobium liniale, ♀ Dendrobium liniale x ♂ Dendrobium mirbelianum, ♀ Dendrobium liniale x Dendrobium bigibbum, ♀ Dendrobium bigibbum x ♂ Dendrobium liniale. Persentase keberhasilan semua persilangan dan resiproknya adalah 100% kecuali persilangan ♀ D.lineale x ♂D. tobaense dan resiproknya tingkat keberhasilannya 0%. Waktu terbentuk buah 3-9 hari, masaknya biji bervariasi antara 81-123 hari dan lama terbentuk protokorm bervariasi 15- 36 hari.

Rice production in Indonesia can not cover the national needs. The low productivity caused by the decline in soil fertility. One way to increase the phosphorus content in the soil is to provide natural phosphate fertilizer and Azolla inoculum. This study was conducted to determine the proper dose of Azolla inoculum and rock phosphate to increase the availability of phosphate and increase the yield of rice plants on land Alfisol. This study uses the two-factor factorial CRD comparative treatment of manure and fertilizer N, P, K. Analysis of the observed data using analysis of variance at 5% level and if there is a significant difference effect followed by DMRT 5% level to compare between treatments. The results showed that treatment of Azolla inoculum and phosphate can increase the availability of phosphate in the Alfisol soil and can increase rice yield. On the parameters available P showed the highest results in the treatment of Azolla 2.5 tons / ha without natural phosphate and Azolla 5 tons / ha of natural phosphate 350 kg / ha which is 10.81 ppm. In addition, administration of Azolla inoculum and phosphate levels give rise to CEC, organic matter, total N in the soil and soil pH.

This research to determine the effect of azolla-based organic fertilizers, rock phosphate, and rice husk ash, and the best combination treatment to peanut yield on Alfisols. The experiment was conducted in April-November 2013 at the paddy fields of farmers in Sukosari village, Jumantono, Karanganyar District and in Laboratory of Soil Chemistry and Fertility and Soil Biology and Biotechnology Laboratory, Department of Soil Science, Faculty of Agriculture UNS for soil chemical and biological properties respectively. This experimental design used was Randomized Block Completely Design (RCBD) with 5 treatments and each repeated 5 times. Statistical analysis of the data using the F test at 5% level of confidence followed by DMRT if any signicant influence. The variabels observed were soil organic matter content, soil pH, total number of soil bacteria, plant height, number of root nodules, and seed weight. The results showed that there was significant differences among the treatments. The treatment of P1 (5 tons/ha azolla compost, 100 kg/ha phosphate rock and 75 kg/ha rice husk ash) provide the highest of soil organic matter content (4.31%) while P2 (5 tons/ha azolla compost, 50 kg/ha phosphate rock and 37.5 kg/ha rice husk ash) provide the highest dry seed yield (1011.09 kg/ha) which was 11.06 % higher than control treatment (910.38 kg/ha).

Research purposes to determine the response of soybean varieties Kaba under protected forest tree stands besides soybean crop response to P fertilizer and manure fertilizer micro coupled with organic fertilizer uptake and utilization of P element to the low light under protected forest tree stands. The research was conducted in JulyDecember 2011. Experiments using Randomized Complete (RAKL) factorial consists of 3 factors, namely fertilization with manure P 1, factor 2 micro fertilization with manure, and a factor of 3 fertilizing with organic fertilizers. Each treatment combination was repeated 3 kali.Faktor first fertilizer P fertilizer P The first factor consists of three levels, namely P1 (50 kg / ha), P2 (75 kg / ha), and P3 (100 kg / ha). The second factor consists of 2 fertilizer micro level, ie M1 (0.5 l / ha) and M2 (1.5 l / ha). The third factor of organic fertilizer consisting of 2 levels, ie O0 (0 tonnes / ha) and O1 (5 tonnes / ha). Data analysis using the F test level of 5% followed by comparison test (DMRT) level of 5%. The results show the interaction between P fertilizer, micro fertilizer and organic fertilizer effect on soil pH, P uptake, and the number of pods. P fertilizer on fertilizer and organic fertilizer micro effects and no significant effect on available P and heavy pod soybeans (Glycine max L.).
