Abstract -  Corn plants are one of the plants that are easy to grow and relatively fast to get results but also a plant that is vulnerable to pests and diseases. The symptoms that arise require an expert or agricultural expert to be able to diagnose. Limited time and expert labor is one of the causes of delayed diagnosis, causing a decrease in farmers' yields. This is the basis for making this expert system by adopting knowledge from agricultural experts about the symptoms of corn disease using the Forward Chaining method. To support the research conducted, researchers used the Research and Development (R&D) research method and the design used the Object Oriented Programming (OOP) method using the Unified Modeling Language (UML). Software is built using the PHP programming language, MySQL as a database, and Bootstrap as an interface design with a web-based system.    

The business of selling coffee in the world is growing more easily and quickly with the provision of a place which is usually called a cafe or shop. One of them is the Titik Hitam Nalar cafe in Jakarta, but the ordering process with customers takes longer to wait for orders and customer payments that are not neatly arranged create conditions that’s are not conducive, resulting in continuous negative criticism. Therefore, an application is needed that helps employees work in every part, both in terms of ordering, manufacturing, and payments, using the FIFO algorithm which focuses on which services are prioritized first in order to reduce negative sentiment from customers. The Android-based application was created by involving every design phase, making it easier for customers and employees to provide a service facility that works well and is suitable for use.  

The purpose of the research conducted was to design an Academic Information System (SIAKAD) at SMA Negeri 2 Rambang Dangku. Data processing at SMA Negeri 2 Rambang Dangku has not utilized the use of information technology to support operational activities, data processing is still recorded manually, such as in processing student assessment data, teacher data, lesson schedule data and student final report data (Raport) and data storage is still done conventionally using paper and cabinets. In collecting data, researchers used qualitative descriptive methods including conducting interviews, direct observation, and literature study. The system development method uses the Prototype method. At the design stage using the Unified Modeling Language (UML) modeling which consists of use case diagrams, class diagrams, and activity diagrams. This system is built using PHP, Mysql, Xampp, and database. The results of this study are a web-based academic information system using the Codeigniter Framework. From this application it is hoped that it will make it easier to process Academic data for SMA Negeri 2 Rambang Dangku so that it is faster and more detailed, and makes it easier to make final data reports on student scores (Rapot).

Over time, the Riau Kepualaun Provincial Tax Management Office which lives in Batam City underwent a name change to become a Regional Tax and Retribution Management Agency for the Riau Islands Province (BP2RD). This study aims to design a dashboard that can assist Eschelon officials in monitoring the performance of the State Civil Apparatus (ASN) at the Regional Tax and Retribution Management Agency of the Riau Islands Province. Because there is no system that displays information related to the work done and completed by an ASN, a dashboard design is needed. Data on the dashboard system is obtained from ASN performance data consisting of activity grouping data, activity weights, monthly targets in one year, and distribution of incentives and employee income benefits based on the achievement of target weights. The modeling system used is the Unified Modeling Language (UML), with the use case, activity, sequence and class diagram stages. While the development of this research system uses the Macro Process method in Object Oriented Analysis Design (OOAD) with the stages of Requirements, Analysis and Design, Implementation and Testing. The dashboard is designed based on a website, using the PHP programming language and using MySQL as the database. Qualitative research techniques, by collecting data and information descriptively. The results of this study display a dashboard in the form of text consisting of the number of employees, targets, target achievement, target percentage, target employee income allowances, and employee income allowances obtained, as well as a dashboard in the form of a pie chart and bar chart for target and achievement percentages respectively. target, it is hoped that this dashboard can assist Eschelon Officials in assessing and monitoring the performance of the State civil apparatus.

STEKOM College which has branch campuses in several places. Employee performance appraisals are carried out by superiors and branch campus coordinators using Ms. Excel. The results of the performance assessment are sent to the staffing department via e-mail. The personnel department will recap the results of the performance appraisal to be conveyed to the leadership. This assessment process takes a long time and tends to be inefficient. In this study, a web-based Employee Performance Appraisal System was developed that can be accessed online by relevant appraisers at the central campus and STEKOM branch campuses. The System Development Method uses a Research and Development (R&D) approach. Assessment elements include 6 (six) aspects, namely: Service Orientation, Integrity, Commitment, Discipline, Cooperation and Leadership. The results of the performance appraisal of educators (lecturers) apart from being used internally as a measurement of lecturers' work behavior, can also be used externally for the assessment of work behavior when the lecturer makes Employee Performance Targets (SKP), as well as being used to assess the performance of education personnel. System modeling uses the Unified Modeling Language (UML). Making the source code program using the Hypertext Preprocessor (PHP) programming language with a web-based MySQL database using Notepad ++ software. The results obtained from the use of the employee performance appraisal system, performance reports can be obtained more quickly, making it easier for the staffing department to obtain data on employee performance appraisals effectively and efficiently.
