The location that is in the closed area and consists of lots of room to play therein will have many challenges when it is developed by using the Global Positioning System (GPS). In the developed system is also necessary to know the location of the children monitored in real time. The use of Radio Frequency ID (RFID) is expected to answer the needs mentioned above. The system developed consists of RFID readers that is installed at the entrance or exit, RFID tags that is carried by the child, a database server that is used to upload data from RFID readers and also an application that is installed on a smart phone that is used to upload the registration data to the database server and download data from the database server to be displayed on the smartphone. Application that is developed to build this system is also equipped with other features such as user info and add friend. User info is used to determine the time of the last tapping did by the child. Add Friend is used to add a child that is to be monitored into the system. In this application, the number of children that can be monitored is limited to 5 children. With accuracy up to 100% at the time of tapping and mapping, systems and applications are developed is reliable to answer the needs.

The method used is quantitative descriptive using secondary data from the Central Bureau of Statistics from the years 2000-2015. Methods of data analysis used correlation analysis, determination analysis, simple linear regression analysis, t-test, and test of elasticity. The results showed: there is a negative relationship between inflation and the human development index (HDI) in the category of moderately correlation coefficient of-0.42 and the contributions made by the inflation of the human development index (HDI) of 17.64% ; if inflation rose by 1%, the human development index (HDI) will decrease by 0.36% with a constant value of 73.33 ; inflation have not a significant effect on the human development index (HDI) and its elasticity is not eslatis (inelastic).

Harga pasar (market price) merupakan harga pada pasar riil. Harga pasar merupakan harga yang paling mudah ditentukan karena merupakan harga dari suatu saham pada pasar yang sedang berlangsung atau, jika pasar sudah tutup, maka harga pasar adalah harga penutup (closing price) dari suatu saham. Pergerakan Harga saham dapat diamati pada indeks harga saham. Indeks harga saham merupakan indikator yang menggambarkan kondisi pasar saham. Dengan adanya indeks harga saham investor dapat mengetahui trend pergerakan harga saham saat ini, apakah sedang aktif atau sedang lesu. Penelitian ini bertujuan untuk melihat pengaruh laba perusahaan terhadap pergerakan harga saham perusahaan yang bersangkutan. Penelitian ini dibatasi hanya pada perusahaanperusahaan yang masuk dalam indeks harga saham LQ 45. Data yang dibutuhkan adalah laba perusahaan yang masuk dalam indek harga saham LQ 45 dan indeks harga saham LQ 45. Metode analisis data yang digunakan adalah analisis kuantitatif, antara lain : analisis korelasi, analisis determinasi, analisis regresi linear sederhana dan t-test.Hasil analisis menunjukkan bahwa laba perusahaan tidak berpengaruh secara signifikan terhadap harga saham indeks LQ 45, hal ini ditunjukkan nilai t hitung < t tabel (0,4164 <1,671).

In order to gain its stability, intentionally a simple filter with a low error rate of 1.67% during its full operation was placed. The time consumed during its steady flying in the air took approximately one second with the height of flying around 1 to 5 meters above the earth.

Low Powered Wide Area Network (LPWAN) is used as a communication network. LoRa devices are configured with a frequency of 470 MHz, spread factor 9, bandwidth of 31.25 KHz, and code rate of 4/5. The study found that the UM402 LoRa module has the farthest network range, up to 1 Km. By focusing on a range of up to 250 m, the LoRa Dragino shield has the fastest data packet delivery time at 0.77 s. UM402 LoRa module has the largest Received Signal Strength Indication (RSSI) value at 50m, it is-34. All LoRa devices used in this research can operate well at the ideal distance of street lights (35 m).

Beside as a billing system, this system also manipulates signal of television remote to switch on or switch off the television. Microcontroller controls the timer using GUI on PC as well as the position of television to be be turned on using I2C communication. The result of this research shows 100% success rate to display the serial number of RFID card while the maximum length between the microcontroller and the television is 140cm.

Menurut Ilmiah : Kompas adalah bentuk akhir dari bahan Organik setelah mengalami proses pembusukan oleh Mikroorganisme dan yang didukung oleh suhu dan udara yang memenuhi syarat proses pembusukan. Dialam terbuka pembentukan kompos seperti pembentukan humus, yaitu melalui proses pelapukan dengan pertolongan bakteri dan cuaca. Masalahnya, dialam, pelapukan itu berlangsung. Oleh karena itu orang berupaya untuk mempercepat proses pelapukan. Upaya mendaur ulang sampah Organik sehingga bermanfaat untuk menyuburkan tanah sangat diperlukan khususnya dikota-kota besar. Masalahnya komposisi unsur hara yang dikandung kompos tidak tetap, karena sangat bergantung pada bahan yang dikomposkan. Biarpun demikian, ciri khas dari kompos adalah mengandung zat Organik dengan kadar yang cukup tinggi.

The problem was the driverdidn’t know condition behind vehicle because of limited of view. The research aimed to make a system that can easily helpdriver in parking his car, by using of ultrasonic parking sensor. The method used in sensor scheme parks is ultrasonicisensor to detect and measure car and balk distance by utilising of 851 family microcontroller as the main system. Theresult indicates that ultrasonic censor effective deep measurement was on distance of 2 cm – 30 m. It is that enoughultrasonic censor is effective to be implemented on censor parks.
