Abstract

Laboran is a designation for technical personnel who operate in a laboratory environment or a place related to scientific, research or testing activities. A chemical worker is a technical worker who has specific knowledge and skills in the chemical field. In schools, chemical workers have a role as workers who supervise and manage chemical laboratories. His main duties include sampling, material testing, data processing and maintenance of laboratory equipment. The school needs to know the performance of each chemical worker, so an assessment of the performance of each chemical worker is needed so that the school knows the best performance of the chemical worker, an additional salary will be added. The performance assessment includes several criteria namely Technical Expertise, Professional Ethics, Problem Solving, Punctuality, Safety and Health, Maintenance of tools and materials, Report Quality, Self-Development, Accuracy, Teamwork and Communication. To simplify the evaluation system for the performance of chemical workers and find out who is the best, a decision-making system is needed, namely a decision support system (DSS). SPK is a system designed to assist decision makers in solving problems or choosing the best option from various available alternatives. In this study the authors used the MOOSRA (Multi-Objective Optimization on the Basis of Simple Analysis) method and ROC (Rank Order Centroid) weighting. The MOOSRA method is a stable, consistent, and reliable multi-criteria comparison method that can provide an accurate assessment of chemical workforce performance. From the application of the ROC and MOOSRA methods, it was obtained an assessment of the performance of the chemical workforce with the chemical workforce alternative with the highest performance, namely the LK07 alternative on behalf of Gueen with a value of 207.95261.

Abstract

Clinic is a health service facility that organizes individual health services and provides basic and/or specialist medical services. If the clinic does not use a computerized system, it will hamper the patient handling process. Obstacles were found at the Rantauprapat Internal Clinic Clinic, including patient registration which was still done manually with patients having to fill out paper forms directly to the clinic, not having a queuing system for treatment, medical record management which was still manual by handwriting. This can take a lot of time in the data search process. The purpose of this application is to facilitate daily operational activities in clinics that run quickly and precisely, as well as medical data management to be more accurate (minimizing human error). The analysis method uses the Soft System Methodology (SSM), and the system development method uses Extreme Programming (XP). This website-based application uses the PHP programming language which is supported by the MySQL database. Based on blackbox testing, all features can run/100% valid. This information system helps the work process in the clinic to be faster, documenting structured medical records, reducing paper use, and facilitating activities in patient care.

Abstract

Water tanks are widely used to store water in the community. However, the filling process still uses a manual method so it cannot monitor/monitor the water level in the tank, so when the water is full in the tank until it overflows it is then turned off. Water tanks are often placed at a height to take advantage of gravity so that water can flow optimally. The high position of the water tank is difficult for users to reach to determine the quality and volume of water. The performance of this tool has 2 conditions. The first condition will discuss the water level monitoring tool in the tank. Using the tool developed, the water pump can be turned on and off automatically which is controlled using a monitoring tool using a smartphone and the Blynk application with a water level indicator. , water flow, and watervolume and Notification of water conditions via Telegram. Technology for distributing and monitoring water in tanks is still limited to conventional means by turning on and opening the water tap. For this reason, a control system is needed that can monitor and control the water volume in several tanks through one application display on a smartphone such as Telegram. By using the NodeMCU ESP8266 as a microcontroller base, an ultrasonic sensor as a water volume measuring sensor, and a Mini Water Pump, the condition of the water volume and all changes can always be monitored via notifications on Telegram. Apart from that, the tool can also be controlled automatically or manually through the commands provided on Telegram. In this way, the concept of using Telegram as a water tank volume control and monitoring system can be the right alternative choice in designing a water tank control system. The research method used is a prototyping system. The expected result is the realization of automatic floodgates to make it easier for humans to carry out their tasks and make the system run more efficiently. Apart from being automatic, this tool has the advantage that it can be controlled remotely using the internet of things. The design of this automatic sluice gate uses an Arduino Uno microcontroller as a processing tool, and is equipped with an ultrasonic sensor, water level float switch sensor, servo motor.

Abstract

The ripeness of oil palm fruit greatly affects the quality of the oil produced. Usually, humans manually detect the maturity of oil palm fruit, a process that can be inconsistent and time-consuming. Therefore, there is a need for automated methods that can improve accuracy and efficiency in determining the maturity of oil palm fruit. The study proposes using the Convolutional Neural Network algorithm to detect oil palm fruit maturity based on digital color images. We expect a convolutional neural network, known for its effectiveness in image analysis, to deliver accurate results in classifying fruit maturity. The aim of this study is to develop and test a model of a convolutional neural network that can classify oil palm fruit into three maturity categories: raw, ripe, and rotten. This study employs a maturity-categorized data set of oil palm images. We built and trained a convolutional neural network model using this data set. We evaluate the model performance using four main metrics: accuracy, precision, recall, and f1-score. We perform an in-depth analysis to assess model performance in each maturity category. The confusion matrix yielded an accuracy of 74.6%. The convolutional neural network model developed showed the highest precision results for the ripe fruit (86.00%), followed by rotten fruit (72.30%), and raw fruit (67.30%). We obtained the highest recalls (85.40%) for the raw fruit category, followed by ripe fruits (75.50%) and rotten fruits (72.30%.

Abstract

The increasing use of social media (Twitter) has made it a platform for the public to express their views on the Indonesian presidential candidate in the 2024 elections. The sentiment expressed through comments on Twitter provides important insights into the public perception of the candidates. However, given the volume and speed at which information is disseminated on social media, manual analysis of this sentiment becomes impractical. Therefore, the use of the Naïve Bayes algorithm for automatic sentiment analysis is considered essential to understanding voter support and preferences. The study aims to analyze Twitter users' sentiments towards three Indonesian presidential candidates in 2024, Anies, Ganjar, and Prabowo, using the Naïve Bayes algorithm. We categorize the results of this analysis into three sentiment categories: positive, negative, and neutral. The methods used in the study involved collecting Twitter comment data related to the three candidates, pre-processing data, labeling data, applying the Naïve Bayes algorithm for the classification of sentiment, and evaluation of the performance of the algorithm performed by calculating the level of accuracy. The results of the research showed that the Naïve Bayes algorithm was able to classify sentiments with fairly high precision, namely 75.54% for Anies, 82.74% for Ganjar, and 75.24% for Prabowo. The conclusion of this study is that sentimental analysis using the Naïve Bayes algorithm can provide significant insights into voter preferences and support. The sentimental data generated can serve as a strong foundation for decision-makers to design campaign strategies that are more effective and responsive to public perception. This research also opens up opportunities for further development in the use of sentimental analysis techniques in politics and campaigns.
