Abstract

Electricity nowadays has become a fundamental necessity for various human activities for various functions. In Indonesia authorized as a provider of electrical energy is Negera Electricity Company (PLN), to know the large electrical energy used, a tool is needed called kWh meters. There are two kinds of analog kWh meters and digital kWh meters. The recording carried out by PLN is now varied from the coming of the officers to record manually or by doing many prepaid systems. This kind of recording is a waste of time and is less effective to do in modern times like this that everything is instant.Things like this will certainly begin to be abandoned when not updated soon. It is therefore necessary to centrally read digital kWh Meter technology that can be accessed anywhere and anytime. Looking at the above problem, it takes an application to see the use of kWh, voltage, current, power, and power factor. To monitor the use of a tenant tenant centrally and anywhere can be accessed.This system uses Raspberry Pi and Website. This system can detect the use of kWh meters now with digital kWh meters connected with Raspberry Pi and the user or admin can see the usage of the website in direct. Users can view graphs of the usage of kWh, voltage, current, power, and power factor. In addition, users can also get notifications if they exceed the specified limit. This system can help record kWh on each tenant as an effective way

Abstract

Warehouse Inventory Picking Order is the process of taking or placing goods in the warehouse according to the demand list. This is an important process in a company, for example PT. XYZ, because it involves operational costs and can affect the customer satisfaction. Efficiency is needed, especially in the speed and accuracy of picking up or placing products in the warehouse. If the picking order process is efficient, the operational costs and  time required will be more efficient too.Unfortunately, this process is often done manually and becomes inefficient due to long and repetitive processes. To answer this problem, a web-based application was designed to determine the route for picking and placing products to minimize the travel distance by using the Discrete Symbiotic Organism Search Algorithm (SOS Algorithm) for discrete data. The final result is that the routing problem can be solved using SOS Algorithm for discrete data with an average distance reduction rate of 38.49% for 25 data.

However, often people are less able to apply a good and correct diet because they do not know what type of diet is suitable and how to set the right food menu.To help people go on a diet, an application is made that can adjust the diet food menu according to the person's condition based on the profile data entered into the application. The method used in creating the diet menu is Genetic Algorithm. This diet application was created and developed for smartphone. The results of the application will provide a food menu arrangement for a week in accordance with user profile data.The test results show that the factors that influence the length of time running the Genetic Algorithm process are the number of epochs and the number of population used. The greater the number of epochs or the amount of population used, the longer the running time duration of the Genetic Algorithm process.

Abstract

Dengue fever is a disease that caused by dengue virus. This virus is transmitted into human body through mosquito bites, aedes aegypti and aedes albopictus. This kind of mosquito are mostly found in subtropical and tropical regions, including in Indonesia. Almost every year, cases of dengue fever occur in Indonesia. Government’s effort to prevent dengue fever have been carried out. Following the development of technology, the government began to save patient data through their own health institution, the community health centers.However, the stored data cannot produce useful information instantly. The data must go through series of processes first before it can become informastion. Data processing methods that can be used are neural network. Because neural network have one function that is prediction. Then, the prediction data can be entered into a digital map for the mapping process. Mapping with digital map that have colors and display the level of sufferers can be said to produce useful information. The result of this program is a website that can display maps in the form of digital map, with data obtained based on prediction results using neural network method. So that later this website can help the government to take preventive measures againts dengue fever.
