PENGARUH LATIHAN RUNNING WITH THE BALL TERHADAP PENINGKATAN KECEPATAN LARI PEMAIN PERSATUAN SEPAKBOLA DJAGUNG KOTA MALANG
No full textAbstract: Football Association Djagung Malang have problem in speed running players, this research aims to improve speed running players. The method used in this research is experiment with a population and a sample of 24 players. Test results show that the hypothesis gained 4,33 F count > F table 4,30 for running with the ball, exercises command to obtain the results of 0,11 F table 4,30. So there is a significant relationship between exercise running with the ball with the exercises of command. Key words: running with the ball, speed running players. Abstrak: Persatuan Sepakbola Djagung Kota Malang memiliki masalah dalam kecepatan lari pemain, penelitian ini bertujuan untuk meningkatkan kecepatan lari pemain. Metode yang digunakan dalam penelitian ini adalah penelitian eksperimen dengan jumlah populasi dan sampel 24 pemain. Hasil pengujian hipotesis menunjukkan bahwa F hitung 4,33 > F tabel 4,30 untuk latihan running with the ball, latihan komando memperoleh hasil 0,11 F tabel 4,30. Sehingga ada pengaruh yang signifikan antara latihan running with the ball dengan latihan komando. Kata kunci: latihan running with the ball, kecepatan lari pemain
Rancang Bangun Burner Dengan Variasi Jumlah Lubang Secondary Airflow 11, 13, 15, 17 Dan Diameter Lubang 5 mm, 10 mm, 15 mm Pada Tungku Gasifikasi
Get PDFThis research aims to determine the effect of secondary air in the furnace burners gasification reactor types updraft gasifier to the temperature of combustion flames using a variation of the hole diameter of secondary airflow 5 mm, 10 mm, 15 mm for a number of holes 17 holes, 15 holes, 13 holes and 11 holes. Fuel furnace used is rice husk with a mass of 1.5 kg of fuel that has been milled with a size of 10 mesh. The wind speed at the blower used by 10 m / s. The results of this research are known variation in the diameter and the number of secondary airflow holes affect the temperature of the fire burning on the burner.
The research begins with the manufacture burner with a variety of secondary airflow hole diameter of 5 mm, 10 mm, 15 mm for a number of holes 11 holes, 13 holes, 15 holes and 17 holes. Then the primary air flow velocity in the gasification furnace which flows from the blower is set at 10 m/s. After it retrieves data that includes temperature combustion flame at the burner with intervals of every 30 seconds and a boiling water by monitoring the water temperature at intervals of every 1 minute.
From this research it can be deduced that the greater the secondary air flow in the burner, the greater the temperature of the combustion flame. However, if the secondary airflow in the burner is too large it will decrease the temperature of the fire burning and water boiling time is getting longer. Referring to the results of a comparison study combustion flame temperature, time of boiling water, and the calculation of thermal efficiency in obtaining best airflow variations secondary hole on hole diameter 10 mm number of holes 11 holes. The highest temperature reached 723 ° C, the gasification process lasted 51 minutes 17 seconds is able to boil water as much as 2 kg in just 8 minutes 38 seconds has a furnace thermal efficiency of 15.16%
Rancang Bangun Sistem Keamanan Kendaraan Bermotor Menggunakan Fingerprint, GPS Tracker, Dan SMS Gateway
Get PDFThe increase in the form of motorcycle theft crime during this period will make the mind of motor vehicle users uncomfortable, even though motorcycles already have a secure key shutter lock feature, but it is still easy for thieves to break in. Therefore, the author made a research on the Design and Construction of Motor Vehicle Safety Systems Based on Finggerprint, GPS Tracker, and SMS Gateway. This research aims to make a safety system design where 3 main components are used as the security system, namely first, the fingerprint component aims to enter a registered fingerprint so that it can start the motorcycle starter, then GPS is a component that aims to find out the coordinate point of the motorcycle location. The location point can be known by entering the SMS message connected to the sim800l. The SIM800L component is a GSM/GPRS module that allows the device to send SMS, make calls, and access the internet over a 2G network. It has a function to connect SMS on a smartphone to this system which aims to find out the location point of the vehicle, perform commands to turn on and off the engine of the motorcycle. This test was carried out on a Supra X motorcycle in 2004, the results of this test registered fingerprint scan succeeded in turning on the motorcycle electricity so that it could be turned on, for the condition of the registered fingerprint damp can be read all but for dusty conditions it cannot be read, then for the distance of sending the user's SMS to the system does not affect the system command either near or far, at a certain distance with a BTS tower for a distance SIM800L of 100m and 1km can read a signal with a duration of 30 seconds at a distance of 2 km with a duration of 2 minutes and at a distance of 3 km with a duration of 10 minutes, then for the duration of the reading of GPS signals when indoors in the morning/afternoon with a duration of 15 minutes when the night is not readable & When outdoors in the morning/afternoon with a duration of 1 minute and at night 5 minutes. and for the duration of the notification delay or SMS delivery delay is affected by the operator's SIM signal on the SIM800
