Assessment of employee performance is expected to know precisely the success in completing work. Employee performance appraisal is also useful for companies in providing feedback to employees and can be used as a basis for agencies to evaluate employee performance. Most government services currently utilize information technology as an information service to the public and the agency's internal services. In institutions, it is necessary to increase and develop the capabilities, knowledge and skills of its human resources, so that it is expected to be able to produce apparatuses that have competitive competencies. Therefore, the authors designed and built an employee performance appraisal system which was implemented using Electre and Web-based and Android methods. It is expected to be able to assist agencies in evaluating employee performance so that they can remain consistent in carrying out their duties as Civil Servants (PNS) within the scope of services to the community. This research uses the R&D method. researchers only use up to step 6. Based on the results of trials of 10 respondents who have assessed the decision making system using the electre method, that the application of employee performance appraisal using aggregate ranking can help provide information on the level of employee performance based on predetermined criteria. Respondents agree that this system is more efficient in assessing employee performance with an average of the old system = 43.50% while the new system is = 84.50%.

The development of information system technology has penetrated the decision support system. Decision support systems can be applied in the selection of raw materials in manufacturing companies. The standard quantity of raw materials is the quantity of raw materials that should be used in the management of a particular product. Determining the standard of raw material quality starts from the application of product specifications, both regarding size, shape, color, characteristics, product processing and quality. Decision Support System (DSS) or Decision Support System (DSS) is a system which is able to provide alternatives in problem solving or can communicate for problems with semi-structured or unstructured conditions. This system is used to assist decision making in semi-structured and unstructured situations, where no one knows for sure how decisions should be made. Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is a concept where the best chosen alternative not only has the shortest distance from the positive ideal solution, but also has the longest distance from the negative ideal solution. This concept is widely used in several MADM (Multi Attribute Decision Making) models to solve practical decision problems. Research development uses the R & D (Research and Development) method which is a research method used to produce certain products and test certain products. In this study, only 6 steps were used. The total score for validation is 28. Based on the above calculation, it can be concluded that the validation results from the experts show a value of 4.0 which is between 3.26 - 4.0 which is classified as a very valid category.

The number of employees who are not enthusiastic in discipline at work has a bad impact on the production division, which is currently still busy with orders for wood processing. This is because the company still applies casual daily wages for contract workers. In addition, there are still many employees who are often absent every day for various reasons. To support the decision of the HRD head, a decision support system is needed to select outstanding employees in the company. In this decision support system will use the promethee method with attributes that have been adjusted to the company's problems

Recent technological developments determine humans to be creative in creating tools that implement technology in it with the aim of facilitating human tasks in daily activities. Inappropriate use of fertilizers can cause losses, both losses on fertilizer, on plants, as well as on the soil and the environment around fertilization. Losses on plants such as unhealthy plant growth and susceptible to disease pests, plant yields are not as expected or low. From the background above, the writer found an idea to create a system or tool that can help farmers in determining the dose of Nitrogen fertilizer in their rice plants, through the storage of the dosage data of each land. The user did five scans, from each scan producing RGB values, each RGB value from five samples was then matched with the BWD dose color indicator. The sample dose results are then sent by the NodeMcu microcontroller to the webserver database. Based on the assessment of the test conducted by 10 Users by Gapoktan Farmers Group of Tosari Kendal Village, the total value of 372 that has been averaged to be 37.2 is between 31 - 40 which is classified in the category of "Very Valid or Very Effective".
