<![CDATA[Abstract— At the 2018 ASEAN Games, Indonesia won 98 medals, the number of medals exceeded the expected target, this achievement could not be separated from the role of coaches who always monitor the condition of their athletes while training on the field. One of the conditions of monitoring athletes can be done by monitoring the heartbeat activity of each athlete during exercise. In this study the authors made a heart rate monitoring tool for IoT 100 meter runners that can be used in the field and send data in real time. Polar Heart Rate heart rate sensor is good to use because the data reading error is 0.4%. 2. heart rate monitoring can only communicate up to 70 meters more.

<![CDATA[The obligation of Muslim towards their relatives who died there are four cases, namely bathing, believing, praying and burying. The community considers that there is no need to think about how to care for the body from the beginning to the finish because there are already their own officers. Rhile in a hadist from ‘Aisyah said Rasullah SAW: “Anyone who bathes a corpse and is guarded by trust and cannot be opened (secret) about the protection of the sympathy for the people there hen comes from sin for hs condition. Based on the hadist mentioned the person who mentioned bathe the corpse in priority is his own closest family, then if the family cannot, then other people can do it, while bathing is included in the case of receiving a corpse based on the results of an interview with teacher Madrasah Diniyah Baitul Athfal by agreeing to him about the management of the body, it is expected if it involves family members. Who can use the world od the sunna of the prophet and also in the future can be used as a successor. In Madrasah Diniyah Baitul Athfal involved in the learning process due to shortages in madrasah are short plus students do not have books about the management of bodies or jurisprudence books become obstacles in the process of learning. Teaching lessons for students or instructors. After obtaining data from data collection, .researchers create a system with predetermined and more relevant methods using the Multimedia Development Life Cycle (MDLC) Method. Based on the results obtained for 9352 and included in the category of Good, then the application was validated that can be applied to the research object.]]>

<![CDATA[The research was aimed to determine the volume and time of giving the natural antibiotic which are optimal for the value of Index Performance (IP) of broiler chickens. The first treatment variable was: giving natural antibiotics with a dose for partition 1 0.05mL / 40 mL water / chicken / day, partition 2 0.1mL / 40 mL water / chicken / day, partition 3 0.15mL / 40 mL water / chicken / day, partition 4 (synthetic antibiotics as a comparison) and carried out for 35 days in a fixed time of 24 hours. Optimal results with the best Index Performance (IP) obtained from the first variable followed by the second treatment variable, the time of giving natural antibiotics for partition 1 given once a day, partition 2 every two days, and partition 3 three days with a constant giving dose 0.15 mL / 40 mL water / chicken / day for 35 days. The parameters observed were: (1) average body weight, (2) weight gain, (3) feed consumption, (4) feed conversion, and (5) number of live chickens. From these data the IP of broiler chickens was calculated and from the two variables obtained the optimal dose and time of giving natural antibiotics. Based on research results from the product, the best of giving natural antibiotic volume is 0.15 mL / chicken or equal to 4.2 mL / 28 chickens which it is able to increase the value of broiler chicken IP until harvest time. From the optimal results obtained in the trial volume variation of giving natural antibiotic, the experiment can be continued with the aim of determining the optimal time of giving herbal antibiotics namely the best results are obtained once a day for 28 chickens because it shows that the giving natural antibiotic is able to increase the IP value of broiler chickens until harvest.]]>

<![CDATA[— The number of motorized vehicles in Indonesia is increasing rapidly every year. Based on data from the Central Statistics Agency (BPS) in 2017, the number of motorized vehicles with Passenger Car vehicles reached 15,493,068 units. The number has increased compared to 2016 amounted to 14,580,666 units. The increase as the number of motorized vehicles has an impact of the availability of parking lots in a number of locations. Every driver who will park the vehicle wants to get the location / lot of the parking lot as soon as possible. However, the unavailability of parking capacity information in a parking area causes the user to go around first to get an unload parking space, if the parking lot is full, the user even has to go back out because he did not get a parking space. This study designed and built an ESP8266 microcontroller and PING ultrasonic sensor provided information about the availability of parking lots were still unoccupied in this monitoring system. It is hoped can improve the efficiency of parking users who are looking for vacant parking lots and make it easier for parking admins in parking monitoring management. The results showed that the monitoring system that was built could provide information about the availability of empty parking lots and integrated databases to store vehicle owner information based on parking cards. Parking lot information is included on the parking card given to users entering the parking area.]]>

<![CDATA[Savonius wind turbine is one of the wind turbines that is more widely used for low energy needs, with more energy needs, this turbine type is very feasible to be developed. This research aims to improve the performance of Savonius wind turbines with variations in turbine blade curvature and variations in wind speed. The research method is a laboratory experiment on the fan test, the blade curvature test variation is 1R; 1.5R and 2R, another variation is the wind speed which are 4.0; 5.5; 7.0 and 8.5 m/s. The experiement results shows that the greater the wind speed, the input power, air mass flow velocity, power output, and efficiency will be even greater; the greater the load force on the turbine shaft, the torque on the turbine shaft will also be greater; the relationship of force loads to power output and turbine efficiency is to construct a parabolic curve; for the same wind speed, the 2R turbine has the lowest rotation, power output and efficiency compared to the 1R and 1.5R turbines; at the same wind speed the 1R turbine produces a higher rotation but requires lower torque than the 1.5R turbine; at low wind speeds (4 m / s) the 1.5R turbine has better efficiency than the 1R turbine, whereas at the high wind speed (8.5 m/s) the 1R turbine has a better efficiency than the 1.5R turbine; The maximum efficiency is obtained at 89.56% in the 1R curvature turbine with a wind speed of 8.5 m / s.]]>
