One of the factors that decrease the production of the soybean crop is the low level of soil fertility. Soil fertility can be improved with the use of mulch combined with proper tillage. This Research is needed to determine the dose and the right soil processing combined with optimal doses of straw mulch to improve the growth and yield of soybean.This research conducted wit Split Plot Design with three replication, with soil tillage as main plot and rice straw mulch as sub plot. Soil tillage arranged with 3 level, O1: maximum soil tillageO2: minimum soil tillage and O3: without soil tillage. Rice straw mulch arranged with 4 level, M0: without rice straw mulch (control), M1: rice straw mulch 2 ton/ha, M2: rice straw mulch 4 ton/ha and M3: rice straw mulch 6 ton/ha. The results showed there were no significant interactions and influences between pemulsaaan treatment combined with tillage on the growth and yield of soybean.

A learning activity that did not correspond with the interest will generated unfavorable achievement. It can be said that with appropriate learning methods can lead to student interst. In learning process we need to caused a learning interest to the students. But in the real class a lot of teachers finds obtacles, because the lack of variations in learning method. Therefore the formulation of the problems is there any affection towards the use of role playing method in student learning interest on tenth grade student of SMA Azharyah palembang, this study aims to determine the effect of the use of the role playing towards the student learning interest of class X on virus material in SMA Azharyah Palembang . this research was done in august until semptember 2016 in SMA Azharyah Palembang. The population of this research was all of X student class of SMA Azharyah Palembang which is divided inti 2 classes and 30 students in average. X1 as a experiment class and X2 as a control class, sampling was done by used sampling jenuh technique. The research was used quantitative research method. The design was used in this research is true experimental design in form of posstest-only control design. To se the interest in students learning is done by using questionnaires and observation sheets. And to measure the effect of role playing method to student learning interst is using t-test. The result show that the learning interst in experiment class in high category was 33%, medium 47% and low 20%. Meanwhile in control class in high category was 20%, medium 50% and low 30% this shows that the experimental class student learning interest is higher compared to the control class. Furthermore there is an influence on students learning interest. Obtained t hitung = 11,75 then compared with t table= 1,671. So the result showed that t hitung > t table. Thus Ha accepted.

This study aims to utilize household waste and used MOL (Micro-Organism-Local). MOL is used to assist the process of decomposition in composting. This study aims to isolate the bacterial origin of MOL with media of different organic materials and the application of the isolated bacteria as a biological fertilizer. Stages of research involved isolating bacteria from MOL vegetables, then do purification. The next stage is to identify the bacteria colony morphology that includes forms, cells, and Gram. This research is expected to contribute to the field, namely: the development of science, research methodology. First, for science to improve information research methods, research for further development activities for people who have an interest in the processing of biological fertilizers and organic fertilizers. Second, the methodology how to obtain microbes for use in applied research. The results were obtained bacterial isolates were collected from three kinds of treatment samples MOL namely MOL to-I (waste vegetable, sugar, rice water), II (vegetable waste, brown sugar, rice water), and III (waste vegetable, sugar sand, coconut water). The result of the isolation and purification of bacteria obtained amounted to 79 types of bacterial isolates comprising 23 species of bacteria from the sample MOL to-1, 30 species of bacteria from the sample to the MOL-II, and 24 types of bacteria from the sample to-III. Overall the data obtained from the sample to the MOL-I, II, and III of the highest number of bacterial cells present in the sample to the MOL-II with a number of types of bacteria most. This type of bacteria that is known at the time T0, T1.

Orchids (Chattleya sp) is popular plant which is favorted by peoples and has higt economic value. It’s price Rp. 562,000 / plant. Tissue culture technique is needed to produce this flower quicky than conventional technique. This study have aims to determine the effect of some medium concentration of organic sweet potato (Ipomoea batatas L) on growing Cattleya sp and for knowing the best of concentration on the growth of Chattleya sp. The method used was Completely Random Design (RAL) with four of factors, that is: 0 g / L, 75 g / L, 150 g / L, and 300 g / L. The results were analyzed with Anova test and Duncan test multiple ranger test at the level of 5%. Each treatment was repeated six times. Parameters were observed are the number of new shoots, long leaf, number of leaves, leaf width, long roots, and height of the plant for 5 weeks. Based on the results of analysis showed that the sweet potato extract on 150 g / L concentration give the best results in long root parameter, the concentration of 75 g / L gived the best results to long leaf parameter and concentration of 300 g / L gived the best effect against leaf width. Same concentrations of sweet potato did not give significantly effect to number of new shoots, plantlets height, and number of leaves.
