Abstract

Imperata weeds are very difficult to control. It is because the weeds have ability to regenerate rapidly through the stolon and seed. Weed control in principle is an effort to increase the competitiveness of basic crops and weaken the competitiveness of weeds. The use of glyphosate herbicide can be mixed with other ingredients; one of them is urea fertilizer. This study aims to reveal whether the mixture of glyphosate herbicide and urea fertilizer at several doses can suppress weed growth. This study used Randomized Block Design factorial pattern, with two factors: (1) dose factor of glyphosate (G); G0 (control), G1 (glyphosate 100 ml liter), and G2 (200 ml liters of glyphosate). (2) urea fertilizer (P); P0 (control), P1 (urea 400 gram), and P2 (urea 600 gram). The results showed that the mixture of glyphosate herbicide and urea fertilizer can suppress the growth and development of imperata weeds. The best treatment was found in a mixture of 200 ml of glyphosate herbicide and urea fertilizer at a dose of 600 grams, while the lowest treatment was found in the control

Abstract

Face recognition has become a common thing used in the field of surveillance and security in computer technology and image devices. This study aims to identify the usefulness of a person's face on 3 test images. This study examines the methods of cropping techniques, image enhancement through intensity measurement, and histogram analysis to improve the contrast and distribution of image intensity. In addition, the Viola-Jones algorithm is used to detect key facial features such as eyes, nose, and mouth. The results of the analysis are then applied in the feature evaluation stage, where usually between facial features are applied to measure the ratio of facial proportions. Furthermore, the comparison of proportional ratios of several images was analyzed using bar graphs and line graphs to evaluate the trend and stability of facial proportions. The results showed the best ratio stability with a smaller variation of the on-off ratio of image 2 which is 0.4762 pixels to 0.4983 pixels. Image 2 is the most ideal for face measurement systems based on geometric ratios because it provides more consistent and visible results.

Abstract

This research is conducting analysis of digital land images using digital image processing techniques. The main purpose of the research is to classify soil fertility based on two-dimensional RGB colored digital soil images. The research is done by extracting features and shapes from the soil image. The research uses methods of segmentation, extraction, and identification against digital soil images. This research is carried out in three stages. The first phase of this research is image pre-processing which begins with the conversion of RGB color image to Grayscale then color conversion to binary which subsequently performs noise reduction with the method Three-layer median filter. The second stage is a process that is divided into the first two stages, namely the process of segmentation by grouping RGB color images into L*a*b which is continued by clustering using the K-means clustering method. The second is the extraction of characteristics of the soil image which is characteristic of shape and texture. The final stage is the identification of soil images that are clustered into two types: fertile soils and unfertile soil. The study achieved an accuracy of 85% which could accurately identify 20 images while inaccurately classifying 5 images out of a total of 25 input images.

Abstract

The development of digital technology is driving innovation in education, particularly in creating interactive and engaging learning media for elementary school students. This research aims to design and build a microcontroller-based English learning media for first-grade elementary school students. This system integrates an Arduino Mega 2560 as the main controller, connected to various components such as touch sensors, RFID, push buttons, LEDs, LCDs, and a DFPlayer module to support interaction and learning. This system offers two main features: visual and audio animal name recognition, and an interactive quiz mode that tests students' understanding by providing multiple-choice questions based on the story. When students touch an animal image, the system displays the animal's name in English and Indonesian, along with pronunciation sounds and descriptions. The quiz can be accessed using an RFID card, and students answer using the touch sensor. Feedback is displayed via LEDs and audio from the speaker. Test results indicate that the system operates well and is responsive, and is able to increase students' interest in English lessons. This research is expected to provide an alternative solution for enriching foreign language learning methods at the elementary level with a simple yet effective technological approach.

Abstract

Employee performance assessment is a way to determine the abilities of each employee. The assessment is carried out to obtain materials for developing the company's human resources. The process of appointing contract employees to permanent positions is still not effective, this results in doubt in decision making which allows errors to occur. In this research, a system for decision making will be built, where this research uses the Multi Attribute Rating Technique (SMART) method. The SMART method is a multi-criteria decision making technique that compares one criterion with another. The data used in this research uses 3 factors and 12 employee data to be selected. For assessment using the SMART method based on criteria and weights, a score above 80 is declared a pass to become a permanent employee. Research using the Simple SMART method can help the Ibnu Sina Islamic Hospital in West Pasaman in managing the data or criteria used in determining the status of contract employees, so that they can determine employees who are in accordance with the quality and quantity of human resources needed and as a basis for making decisions. become a permanent employee.

Abstract

Information is the result of processing data from one or various sources, which is then processed so that it provides value, meaning and benefits. In the modern era, the use of technology plays a very important role as a means of information and promotion, especially in the field of websites in conveying information. The activity implementation plan carried out by the institution to determine the time period for completing activities still uses estimates as a guide. These estimates result in uncertain completion times. This is of course a problem in the implementation of activities, because late completion times result in time differences with the initial planned targets. Based on these conditions, the delivery of information is felt to be less than optimal because it does not yet have a website page, so the author feels that the West Sumatra Center for Public Policy Studies (PSKP) requires an information system that is able to support activities and provide information about the institution to be more effective and efficient. Then a schedule of the activity implementation process is needed from start to finish. One method that can be used for scheduling is the critical path method (CPM). This method is part of the work network method which is oriented towards determining schedules and estimating them which are deterministic (certain). With this CPM method, all activity processes are in accordance with the initial target
