Wheat leaf diseases such as yellow rust and powdery mildew are very harmful to wheat yields worldwide. It is important to detect these diseases as early as possible so that losses can be minimized. In this work, we have used lightweight convolutional neural networks (CNNs) and Transformer-based methods to detect wheat leaf diseases under complex environmental conditions. In the first study, we tried several lightweight CNN models, such as MobileNetV3, ShuffleNetV2, GhostNet, MnasNet, and EfficientNetV2. These models were trained using different learning methods and achieved the highest accuracy of 98.65% using MnasNet and a fine-tuned learning rate. The second study focused on detecting yellow rust with UNET Segmentation and Swin Transformer classification methods. They achieved 95.8% accuracy in the field without manual intervention. These studies created a complete pipeline, including finding and delimiting wheat leaves from a complex background. They used YOLOv8 to quickly find leaves, then performed Segmentation and classification. The results showed that the combination of Segmentation, lightweight CNN, and Transformer techniques can handle leaf disease detection in nature with different backgrounds. This system has high accuracy and good efficiency for use in the field. This method can help the development of smart agricultural applications by accelerating and facilitating automatic detection of wheat leaf diseases. Using technologies such as Convolutional neural networks, Transformers, and Segmentation to overcome complex backgrounds.

Diseases in chili plants are a serious problem that can significantly reduce crop yields and production quality, making early detection essential to assist farmers. This study uses a Convolutional Neural Network (CNN) approach with Transfer Learning methods to classify diseases on chili plant leaves. Infected chili leaf image data is processed and trained using a pre-trained CNN model to improve classification accuracy, even with limited data. The results show that this approach successfully identifies various types of diseases on chili leaves with a high level of accuracy. This approach is expected to be an effective solution for the agricultural sector to achieve faster and more efficient plant disease detection.

The diversity of the age of educators in Indonesia affects the quality of education in each region. The uneven age distribution, with a shortage of productive teachers and an increasing number of teachers approaching retirement, is a challenge in equalizing the quality of education. This study uses a quantitative approach with descriptive analysis to analyze the age distribution of educators in four provinces: South Kalimantan, West Sulawesi, West Nusa Tenggara, and Bengkulu. Data from KEMENDIKBUDRlSEK 2023 were analyzed using SPSS to calculate the mean and median, presented in tables, histograms, and frequency polygons. The results of the study show significant differences in the age distribution of educators and the imbalance in the number of teachers and students in several provinces, which have an impact on the quality of education. This study provides important insights for more effective education policies by considering the age distribution of educators.

Jonathan Adi Prasetyo — Fri, 20 Dec 2024 00:00:00 +0000

The development of sat technology is currently growing rapidly, today's technology is no longer a compliment but has become a necessity. One of them is in the world of fish farming. Developing technology offers a wide range of automatic device options that are deliberately created for personal and group convenience. The automatic device itself offers us not have to do the activity repeatedly, but the repetitive activity has been done with the automatic device. One of them is a fish feed system based on the Internet of Things. Challenges arise when the owner is busy with his activities while required to provide fish so that the fish continue to grow properly. Therefore this research was conducted to overcome the problems that arise when the owner cannot provide feed directly or provide feed at the right time because he has other things to do. NodeMCU can be used as a tool to receive input and output of a sensor and as a device that can connect to the internet because NodeMCU is equipped with an ESP8266 chip, by adding a servo motor as a feed aid, and the Blynk application for scheduling media, then feeding can be done and scheduled remotely.

This research aims to develop a decision support system that supports the appointment process of permanent employees from contract employees using the TOPSIS method. Given the importance of having quality human resources, an objective and efficient selection process is needed to ensure the quality of employees. The criteria used in this research include attendance, performance, discipline, loyalty, offense, length of service, and last level of education. The TOPSIS method was chosen due to its ability to analyze alternatives based on distance to positive and negative ideal solutions. The evaluation results show that this system can provide appropriate recommendations in determining employees who are eligible to be appointed as permanent employees, with a high level of accuracy. This research concludes that the application of a TOPSIS-based decision support system is very effective and recommended for use in the employee selection process in a corporate environment.

Primasari Pertiwi, Abinawanto — Mon, 23 Dec 2024 00:00:00 +0000

The research aims to determine the effect of several concentrations of egg yolk as an effective natural cryoprotectant for cryopreservation and to analyze the quality of lukas fish spermatozoa (Puntius bramoides Val) 48 hours after cryopreservation. This research used a 9 treatments and 4 replications. The concentration of egg yolk used as a cryoprotectant was 0% (negative control), 5%, 7%, 9%, 11%, 13%, 15%, 17%, and 1% Carboxymethyl Cellulose (CMC) was used as a positive control. The results showed that the use of several concentrations of egg yolk as a natural extracellular cryoprotectant was able to significantly influence (P<0.005) the quality of Lukas fish spermatozoa 48 hours after cryopreservation. The use of egg yolk concentration of 9% is the optimum concentration in maintaining the viability of Lukas fish spermatozoa with the average percentage obtained each being 80.75 ± 1.55%.

The Decision Support System (DSS) for selecting employee training programs based on competencies is a vital tool for organizations aiming to enhance the quality of their human resources. This research utilizes the Simple Additive Weighting (SAW) method, which is recognized for its ability to provide objective, mathematical evaluations in determining the best training programs. The criteria used include training relevance, duration, cost, and the quality of the training provider. Using the SAW approach, alternative training programs are evaluated based on weighted criteria values, resulting in effective and efficient recommendations. This system was implemented in a company, and the results demonstrated that the SAW-based DSS significantly improves accuracy and objectivity in decision-making processes related to employee training.

Almuhajrin, Wasis Haryono — Thu, 26 Dec 2024 00:00:00 +0000

Clinics are health service facilities that provide individual health services providing basic or specific medical services. Medikatama Nusantara Clinic and have not been optimal in the use of information technology in some of their work systems, one of which is the registration section which still uses paper-based bookkeeping media. This causes several obstacles that often prevent clinic staff or clinic management from obtaining information related to registration data and medical records. Based on the problems faced, the writer concludes the formulation of the problem, namely, how to make a system to store patient data to make it better. The purpose of this research is to develop a clinical information system for patient data at the Medikatama Nusantara Clinic, which currently does not have an information system. The system development method used by the author is Rapid Application Development. RAD is a systems development strategy that emphasizes speed of development through extensive user involvement in construction, fast, iterative and incremental. Based on the research that has been done, the authors can conclude that the patient registration information system makes it easier to store patient data and staff can work well. In addition, this patient registration information system makes it easier to report patient data because the input data has been recorded automatically and is running well.
