Employees are the main and most important element in the running of a company. The quality of employees is a determinant of how an employee's foundation is. In order to improve the quality of each employee, it is necessary to separate employees, between contract employees and permanent employees. the large number of employees may make the management confused in determining who should be made permanent employees. Therefore, a system is needed that can assist the government in selecting permanent employees. The system is a decision support system. A decision support system is a system where the process is carried out using a unified system with a method or more than 1 (one) method that is carried out using a computer base. SPK is used to assist certain elements in choosing or making a decision. Many methods can be used in DSS, in this study the PSI method was used. PSI is a method used in solving problems where the problem has many alternative choices of attributes. With this study, the results were that the best alternative was Dicky as an alternative B15 with a value of 0.8977, which in the end was suggested to be a permanent employee

The administrative system is very important in the world of trade and transactions, because with a good administrative system, business owners can know and control the flow of goods circulation and people around public services. Therefore, it is necessary to develop village potential trough out Microsoft Office Excel training so the community will be developed and increased the productivity of the potential in the village. Microsoft Excel is a program issued by Microsoft Office with a function as a numerical data processing program. Various kinds of data processing activities, making graphs, calculating data and others can be used in Microsoft Excel. Thus, training related to Microsoft Excel is carried out and it is hoped that this knowledge can improve abilities and support the potential that exists in Bojonggede village.

Lymphadenopathy or often known as lymphatic disease is a disease that is very risky if not handled properly. There are so many signs or symptoms of this disease that have not been known to the public, some even consider it an ordinary lump that grows on the human body and do not know that they are experiencing lymphadenopathy in themselves [3]. Usually to find out the disease in the lump, do an examination to the hospital or consult a doctor. Based on these problems, a technique or method is needed that can facilitate the community in diagnosing the early symptoms of this lymphadenopathy, one of which is by using an expert system. An expert system that in solving problems with oral and nail diseases, one of them uses the Naïve Bayes method. Naïve Bayes is a probability method by predicting future opportunities based on past experience. With the aim of making it easier for ordinary people to take the first step in dealing with diseases that are experienced about lumps on the body. Based on the results of the application of the Naïve Bayes method, the results are based on the input of the user's symptoms, the accuracy of the results of lymphadenopathy in users with mild lymphadenopathy is 32% and acute lymphadenopathy is 68%. critical

The irrigation controller in lettuce plantation irrigation aims to optimize the water that enters the ditches around the lettuce plantations so that the lettuce plants are not easily damaged due to stagnant water during the rainy season which can result in crop failure. Using the literature study method, collect data from sources that are relevant to the topic of the problem which is the main cause of crop failure in lettuce. From the existing conditions, it is necessary to design a tool to be able to minimize the water discharge to overcome the problems that occur. Schematics on the design and workings of the device were obtained from field observations and designed in the form of a prototype and similar to the logic of the tool when it works. The instrument was instructed as a control for the tool to measure the water discharge equivalent to the need in the ditches around the lettuce plants and the tool tested applied voltage measurements when the tool performed at time intervals that matched the initial requirements. The results of the research applied to the tool can work automatically and maintain the stability of the distribution of power to each sensor used with test intervals according to the results of the needs of lettuce plantation farmers.

Congestion has become a significant problem for road users, in particular, the occurrence of queues at intersections. Traffic lights have an important role related to the control system to regulate road users so that they are orderly in every queue at the crossroads. The current traffic light control system still uses a static timing system, so to solve this problem an innovation is needed in the form of making a traffic light monitoring device at a five-lane intersection using a web-based microcontroller as the input used to control road user traffic lights. The design of this tool uses a module with the ESP8266 series as a module capable of managing and sending data via internet media, by installing three LEDs each on five lanes which will be processed automatically, equipped with a buzzer component as a marker where traffic light signs are placed. . The circuit will be controlled using an Arduino type microcontroller with the ATmega2560 series. The results of the tests carried out show that the website that has been made can control LEDs, with a buzzer as a marker of information regarding the state of the traffic light, it can work with related provisions at intersections.
