Technological developments are so rapid at this time to make people want always to be creative and trigger to create something new which can be applied and can use quickly and practically and control from close range and distance. In this research how to design home security system using PIR sensor (Passive Infra Red) based on microcontroller. Where this safety will work if the PIR (Passive Infra Red) sensor detects any human being that does not want to enter into the house, and then the micro controller process and instructs cell phone 1 to send an alarm signal in the form of SMS (Short Message Service).

Plants need water to grow well, so watering must follow the plant's needs. Parameters that affect the process of watering plants are air temperature and soil moisture, thus, we need a control system that can make decisions in the form of watering time to meet plant water needs according to their needs, namely an automatic watering system. Fuzzy method can be used for human-like decision making in a control system. This study uses the Sugeno fuzzy method which is integrated into the Microcontroller as the controller. Testing of this system is carried out on eggplant plants which are regulated based on how long the watering time is so that the air temperature and soil moisture are following the plant's needs. The test resulted that the effective watering time interval so that the eggplant soil moisture was maintained at 40-60% was 21 seconds. It can be concluded that the fuzzy inference embedded in the design has been able to overcome the problem of watering eggplant plants, where the test shows that after the watering process, the soil moisture value can be maintained at an average value of 55% so that the soil moisture is following the needs of the plant.

The Working Principle Of Solar Cells Is Very Simple. Solar Cells Are An Energy Conversion Tool That Transforms Solar Energy For Electrical Energy. Energy From Sunshine Accommodated Then Converted into Electrical Energy. Such Energy Can Be Used For Running Various Kinds Of Electronic Devices Starting From Lighting Lights, Moving Motor, And Many More Others. The following article is the effort that must be done to make solar energy as an alternative energy in overcoming the needs of household electricity in the village of Pardamean Dusun Gunung Tua Kec. Pahae Jae Kab. North Tapanuli North Prov. Sumatera Far Inside With Difficult Access And Unspoiled Electricity PLN.

Indonesia once's of country use more transportation, and also state spends more population, Smart Hybrid Vehicle is an Important issue for vehicle in college. This paper presents implementation transportation eco-campus for electric scooter and recharging solar cell in parking lot areas University Pembangunan PancaBudi. It allows us to evaluate a broad range of Plug-in Smart Hybrid Electric Vehicles (PSHEVs) and Plug-in Electric Vehicles (PEVs) charging scenarios and stochastic models of the power that is the demand by PEVs in the parking garage, and the output power of the PV panel are present. To impact of the PSHEVs' charging on the utility grid, a fuzzy logic power-flow controller was designed. The charging with solar cell helps to reduce emissions from the power grid but increases the cost of charging. Moreover, it offers more flexibility to prepare for the emergence of new technologies (e.g., Vehicle-to-Grid, Vehicle-to-Building, and Smart Charging), which will become a reality shortly. The system structure and the developed PHEV smart charging algorithm are described. Moreover, a comparison between the impact of the charging process of the PHEVs on the grid with and without the developed smart charging technique is presented and analyzed.

This research aims to explore the brand switching of cooking oil to other brands made by the purchasers, especially homemakers. Another goal is to analyze the various considerations of homemakers when choosing and deciding to switch to another brand. The authors also explain how the market share of cooking oil brands in the present and future and use descriptive analysis by presenting the results of information from homemakers as consumers of various brands of cooking oil. The data collected in this research are primary and secondary data. The result of this study is that consumers who switched to Tropical and Sania were more than consumers who moved from both brands. Meanwhile, Sunco consumers are the most consumers switching to other brands. The most popular brand of cooking oil is Bimoli. The next sequence is Tropical and Sania. Most consumers choose Bimoli cooking oil because this oil is classified as a famous product, easily obtained, and the habits of the family. Unlike Tropical, most consumers choose because of the economical price. For Sania, consumers who choose this brand is due to nutritional value information and is classified as a famous brand. The results also show that market share is still dominated by Bimoli, followed by Tropical and Sania. Bimoli's market share growth is predicted to grow by 2.4 percent. A significant market share increase occurred in Sania, while there was a decrease in market share for Tropical.
