<p><em>The demand for electric power increases along with the development of technological progress and development. The use of electricity is an important factor in people's lives, both in households, lighting, communication, </em><em>and </em><em>industrial. The purpose of this research is to calculate the frequency response before load shedding, to calculate the frequency response after load shedding and to analyze the load recovery after normal frequency in the load. The methods to be used in writing and discussing this research are: Observation Method, Interview Method / Interview, Literature Study Method. Based on the calculation of the data in the previous chapter, the following conclusions can be drawn, the calculation of the conditions before carrying out the load shedding is based on the rate of decreasing frequency from the result obtained is 1.6 Hz / s, then to calculate the time used in determining the frequency at the time of load shedding then the results obtained are 54 Hz, Meanwhile, to calculate the frequency after load shedding that is obtained is 49.1 Hz, Calculation of load shedding time is expected when there is a decrease in frequency of 10.5 seconds, Calculation of the load rate of increase expected after load shedding then the optimal load value that must be removed is 5.55 w. </em></p>

Learning from the development of new technologies using the Internet as a monitoring medium, it can be ascertained that gps can be applied in various fields. These gps systems offer efficient improvements in vehicle monitoring and obtaining accurate and real time data. That with thedevelopment of new technologies that can be done that was the work-manual work using a computer that is Raspberry Pi. Data collection method is done by observation method, interview method and literature study, tool design method is done by using Fritzing application as a tool to design the system to be made and design of prototype to be built. But so far some are still local (Intranet), such as Infrared, Bluetooth and Wireless LAN. With the latest technology changing the local paradigm (Intranet) into IoT / Internet Protocol Based. In designing this tool required Raspberry Pi as Gps media as well as vehicle monitoring media using GPS, equipped with GPS module as a monitoring medium with ease. The creation of this tool may make it easy for vehicle owners to monitor vehicles remotely and provide reports in realtime.

This research was conducted to determine the knowledge and conservation efforts of the people of Doyo Lama villageand Harapanvillage. The research was carried out for three months, namely, from July to September 2020, using the observation method; interview method; documentation method; and literature study methods, and analyzed descriptively qualitatively. The results showed that knowledge about sowang wood (Xanthostemon sp.), is a traditional knowledge passed down from generation to generation orally. The people of Doyo Lama village call sowang by the name toang (meaning hard and strong), and Harapan village named howan(meaning wood that is durable and not easily weathered). The people of Doyo Lamavillage know two species of sowang wood, namely broad-leaved species and small-leaved species. The people ofHarapan villagealso recognize two species, namely the red-flowered species and the yellow-flowered species. The broad-leaved species and the red-flowered species are Xanthostemonnovoguineensis species. While the species with small leaves and yellow flowers are Xanthostemonpapuanus. Traditional knowledge and use of sowang wood by the people of Doyo Lama villageand Harapanvillage is decreasing, influenced by the development of modern life, because until now there have been no efforts and conservation activities for sowang wood in the two villages and there has been a shift in cultural values from traditional be modern.
