Abstract

One of the problems of acid soils such as Latosol is very low in P-availabi/ity due to high P-j'vcation in those soils. Sincesoils is deficiency of P, adaptation of plants and microorganisms to overcome deficiency of P in soil is by producing phosphatase. Phosphatase. is an enzyme that able to catalize transformation of organic P to inorganic P, and produced by plant roots, residual of plants and microorganisms. Organic mailer as a source of P besides N and energy formicroorganisms, and then rock phosphate as an alternative P fertilizer were used in this research. The objective of theresearch was to study the effect of organic matter (Centrocema pubescent) and rock phosphate application on phosphataseactivity and P fraction of Latosol soil from Darmaga, Bogor. The experiment was designed by completely randomized designwith two factors and three replications. The first factor was application of organic matter with the rate of 0, 2.5, and 5 %, and the second factor was application of rock phosphate with the rate of 0, 20, and 40 ppm P. Soil equivalent to four hundred grams of oven dried soil, organic matter, and rock phosphate were mixed based on the treatments of the experiment, and were placed in plastic pots, and then were incubated for 8 weeks period After incubation period, the soil were air dried and analyzed for phosphatase activity, available P, and organic and inorganic P. The result showed that organic mailer increased activities of acid and alkaline phosphatase, organic and inorganic-P of soil. On the other hand, rocle phosphate increased inorganic P but decreased activities of acid phosphatase,. Application of organic matter or rock phosphate on activity of acid phosphatase was higher (2.3-2.6 times) than on alkaline phosphatase. There was no effect of combinationbetween organic matter and rock phosphate on the activity of phosphatase and organic/inorganic P. Combination betweenorganic matter and rock phosphate Significantly affected available P. In each rates of rock phosphate given, the increasing rate of organic matter increased available P in their interactions, on the contrary, in each rates of organic matter, the increasing rate of rock phosphate did not affect available P in their interactions. However it was tended to decrease in therate of 40 ppm P.

Abstract

Guano is a material originally from sea bird or bat excrement. This material is an important source of P fertilizerduring nineteenth century and the early part of twentieth century. The development of artificial fertilizers and the depletion of guano deposits in Peru caused guano negligibled from world fertilizers trading. Recently, guano appeared in fertilizers trading and sciencetific publications again due to the development of organic farming and increasing the price of energy sources for fertilizer manufacture. Based on its origin, guano is classified into sea bird and bat guanos; and based on its composition guano is grouped into nitrogenous dan phosphatic guanos. Moreover, guano deposits are divided into two types: cave guano and insular guano deposits. The main component of guano is N, P, and Ca elements, and the additional elements are K, Mg, and S. Both nitrogenous and phosphatic guanos are important organic fertilizers because the N content of nitrogenous guano and the P content of phosphatic guano are far higher than those of manure, agricultural waste, or muniCipal waste. In Indonesia guano deposits are widely distributed in Sumatera, Java, Kalimantan, Sulawesi, Nusatenggara, and Irian Jaya. The most deposits are cave guano deposits which contain thousands to hundred thousands tons of guano.Consequently, it is highly potential to develop direct use of guano in our country. Futhermore, results of experiments indicated that phosphatic guano has high possibility to be used directly as P fertilizer.

Abstract

The researchs of immunocontraception have done in ZP3 of several species, but have not been done in ZP3 of goat. In preliminary study, gZP3 protein was effective prohibited of graviditation of mice. The aim of this study was to prove the potency of gZP3 protein to prohibit in vitro fertilization of mice as an animal model. Antibody of gZP3 produced on mice. Immunized mice serum was analyzed using Elisa and Dot blotting method. Antibody of gZP3 supplemented into M-16 media for oocyte incubation, continued with in vitro fertilization. The result showed that antibody titer of immunized mice serum was higher (p

Abstract

Background: Teenage is a period of transition or the transition from childhood into adulthood. At this time, adolescents undergo various changes, changes that seem obvious are physical changes and is accompanied by development of reproductive capacity. Changes that occur in the affecting teens view themselves. Self-concept in adolescents more emphasis on appearance; nose, large ears, short stature, or body frame is large resulting in poor adolescents assessed against him. Anxiety is often caused because teenagers are not able to adapt and think the reality of the changes that occur as the body shape changes, the development of secondary sex characteristics and roles. Purpose: To determine the relationship of self-concept and anxiety in adolescent girls at MTs Srebegan Methods: Quantitative research, descriptive research design to study the correlation. The study design was cross-sectional. The sampling technique used is proportionate stratified sampling. The sample was student of class VII, VIII and IX MTs Srebegan Ceper Klaten by 65 respondents. Results: The relationship of self-concept with anxiety were analyzed using chi-square (X2) with a confidence level of 95% or α = 0.05 obtained X2 value of 14.841 count. X2 price table with df = 2 at 5.991 then X2 count is greater than the table (14.841> 5.991) and p-value = 0.001 is less than the value of alpha (α = 0.05) which means that the alternative hypothesis (Ha) that can interpreted that there is a significant negative relationship between self-concept and anxiety in adolescent girls in Srebegan MTs. Conclusion: The negative relationship between self-concept and anxiety in adolescent girls can be interpreted more positive self-concept will be more mild anxiety in adolescent girls.

Abstract

Background: Mental health is one of the four major health problem in developed countries, although the problem is not considered a mental health disorder that causes death directly, but the disorder can lead to the inability of individuals to behave that can inhibit development because they are not productive (Hawari, 2009). Purpose: The purpose of the study to Know medication adherence relationship with relapse in patients with hallucinations in Polyclinic Hospital Mental Prof. Dr.. Soerojo Magelang. Method: The study was a descriptive correlation study, with cross design sectional.research time held in November 2012-August 2013, the population in this study were 210 patients hallucinations. sampling techniques by mean of disproportionate stratified random sampling with 61 correspondents in accordance with inclusion criteria. Results: There was no significant between medication adherence relationship with relapse in patients with hallucinations, a score of 10.676 X2 count. Price X2 with df = 1 for 3,841 then X2 count is greater than the X2 table (10.676> 3.841) and P-value = 0.001 is less than the value of alpha (α = 0.05) which means that the alternative hypothesis (Ha) is accepted that there medication adherence relationship with relapse in patients with hallucinations. Conclusion: There was a significant between medication adherence relationship with relapse in patients with hallucinations. Good medication adherence would reduce the risk of relapse in patients with hallucinations.
