The problem with opening the gate opening now is to work manually, which is opening and closing as well secure with a key, then pull or push the gate. This is certainly less efficient and less effective because it requires time and energy to do it. One solution is to make a control device it works automatically ie using a microcontroller, Bluetooth, and servo motor, with communication devices Android-based handphone. Laboratory experimental methods have been carried out to make 'open and close tools the gate with a cellphone'. Based on the results of the trial using Bluetooth and mobile phones, this tool can work up to a distance of 11.5 meters with a response time of 1 second. This prototype tool is very cheap, practical, efficient and effective in opening and closing gates. Not all Bluetooth can open and close gates because the password is required for the accent. This prototype is a simulation tool that works well.

The smartphone is an electronic device that is portable or easy to carry everywhere. The influence of technology makes students dependent on smartphones, causing various impact. The Negative effects that occur in the brain result are difficulty in concentrating the real world, wasted time, and others. Does will possibility generating the learning process which shows students are not optimal. Response-stimulus of time from learning activities very disturbing when students play which smartphones then listening will explain the material. Therefore, the process of cognitive absorption is lower. The positive impacts of smartphones are to facilitate communications, increase knowledge, the emergence of new learning methods. Literacy is the ability to read and write. Literacy movements can reduce addiction on the smartphone, especially during learning. Besides counseling about smartphone use. The purpose of the study is to find out the result of the students’ captivity during learning to describe phenomena that occur in the classroom during the learning process. The method applied to collect the questionnaire through the description. This research was conducted in SMAN 1 Batujajar, a sample of class XI IPS 3 which contained 41 people. The result of this study indicates that the influence of smartphones can inhibit the learning process.

Thisstudy aimed to determine the effect ofvariables, consisting of Return on Assets (ROA), firm size, sales growth and the structure of the asset (asset structure) on the capital structure. Companies used in this study are Transportation Services companies, listed in Indonesia Stock Exchange for the period of2008-2010. Samples that meet the criteria to be investigated consist of 14 companies. An analytical technique used in this study is multiple regressions and hypothesis testing conducted partially and simultaneously. The analysis shows that simultaneously. Return on Assets (ROA), firm size, sales growth, and the structure of the asset (asset structure) significantly influence the company's capital structure. Partially, the firm size, and sales growth have a significantly positive effect on the capital structure while Return on Assets (ROA) and the structilre of the asset (asset structure) do not significantly affect company'scapital structure.

This report is motivated by the findings in the field where the condition of the fifth grade students of SDN Negla 03 has the characteristics of relatifely low learning outcomes in science learning in the basic competency “Describe the Properties of Light”. One alternative to help improve learning outcomes. The authors make improvements through the applications of eksperimental methods and cooperative learning models. This report describes the implementation and results of research onimproving learning on the use of eksperimental methods and cooperative learning models.The research used the CAR method which was carried out in 2 cycles. Each cycle consists of four stages including planning, implementation, observation and reflection. The subject of this research is the fifth grade student of SDN Negla 03. The instruments used in this research are qualitative and quantitative data. Qualitative data obtained trough student and teacher activity observation sheets, while quantitative data were obtained through formative tests. The results showed an increase in learning outcomes along with the increase in student activity, motivation and cooperation in learning. Thus, the application of cooperative learning models can improve student learning outcomes.

The low results of learning mathematics shows not achieve the purpose of learning is optimal. It can be seen from the results of the daily test scores of grade IV SD Negeri Ronggo 03 on ordinary and mixed fraction material , it shows that 9 out of 24 students or 37% complete and 15 students or 63% are incomplete with KKM 70 The aim of research to describe enhancer of an outcome study of mathematics material fractions plain and mix in with the model pembelajarann Realistic Mathemathic Education (RME) with media objects nyata.Penelitian have implemented two cycles with the phases of planning , implementation , observation and reflection . From the results action shows an increase in mathematics learning outcomes of ordinary fractions and mixed materials through the RME learning model with real object media , it can be seen from the results of student learning evaluation in pre- cycle reaching 37%, increasing in cycle I 75%, cycle II 100% so that there is an increase from pre- cycle. cycle until cycle II amounted to 63%. The RME learning model with real object media can help students improve learning outcomes and improve the quality of learning on ordinary and mixed fraction material.

Bacillus merupakan rizobakteri yang dapat menghambat patogen tanaman dengan mekanisme antagonis berupa antibiosis. Bacillus spp. dapat mengendaliakan penyakit jamur akar putih yang disebabkan oleh Rigidoporus sp. pada tanaman karet. Penelitian ini bertujuan untuk mendapatkan isolat bakteri Bacillus spp. dari rizosfer tanaman karet dan potensinya sebagai agens hayati dalam mengendalikan penyakit jamur akar putih pada tanaman karet. Isolasi bakteri dilakukan dari rizosfer pertanaman karet sehat dan selanjutnya untuk mengetahui kemampuan agens hayati dilakukan uji antagonis terhadap Rigidoporus sp.. Pelaksanaan pengujian bakteri dilakukan secara in vitro dan dilakukan juga uji karakterisasi bakteri. Hasil isolasi dari rizosfer pertanaman karet diperoleh 108 isolat bakteri, 106 isolat bakteri negatif hipersensitif, dan 71 isolat bakteri yang memiliki kemampuan menghambat koloni jamur akar putih secara in vitro. Isolat bakteri rizosfer mampu menekan pertumbuhan Rigidoporus sp. sebesar 21,86 % sampai 46,05 %. Hasil pengamatan menunjukkan Bacillus sp. yang diperoleh mampu menghasilkan enzim kitinase, menambat nitrogen, dan melarutkan fosfat, sehingga bakteri ini mampu berkompetisi mendapatkan nutrisi yang akhirnya mengimbas tanaman sehingga tahan terhadap jamur akar putih.
