Information is delivered by gestures or movements using specific tools such as flags, paddles or rods. Teacher and instructors are needed for learning semaphore in conventional way as they will give examples and make correction when such an error occured. Based on the practical need to provide an alternative way to learn semaphore, this research proposes the use of geometry algorithm to develop a semaphore gesture recognition based on skeleton images that read from Kinect sensor. Euclidean distance and law cosines are two formulas that applied to generate gesture parameters of each alphabet. Recognition is achieved by comparing a pair of values of model and real-time gesture. Accuracy of this system that have been measured using RMSE with 30° of tolerance yields 90.76% for Alphabet and 88% for Word.

Many tourist places are not open to prevent the transmission of this virus. Madura is one of the islands located in the province of East Java which has many tourist attractions. Bangkalan is one of the districts in Madura which has 21 tourism spots. There are many tourist attractions scattered in Bangkalan district, but there is a problem arisen in determining the shortest path to get to these tourist attractions. There are several route options available in each area. Optimal value search can be used to obtain the highest and lowest values of a problem. One of the popular problems that can be solved by optimization algorithms is the Traveling Salesman Problem (TSP) to determine the closest route using the Ant Colony Optimization algorithm. The ant algorithm is an algorithm adopted from the behaviour of the ant colony. An ant colony can find the shortest route between the nest and a food source based on footprints on the trajectory it has traversed. The more ants that pass through a track, the clearer the footprints will be. Ant Colony algorithm is very appropriate to be applied in solving optimization problems, one of which is to determine the shortest path. The final result of this discussion is the algorithm used is able to determine the shortest path to find tourist destinations as an alternative route. The accuracy results obtained are 100% with a rho value of 0.5, an alpha value of 1, and a beta value of 1.

Malang Regency is one of the producers that ranks 10th in corn production in the East Java region. People are very interested in planting corn because this crop commodity has many benefits so as to make the demand for production increase. There was a significant increase in market demand, but the uncertain amount of production made the supply of corn plants unable to be fulfilled properly. In this study, it predicted the demand for corn by using the Backpropagation Neural Network algorithm in Malang Regency. The data in this study were obtained from the Department of Agriculture and Food Security of East Java Province starting from 2007-2020 every month using maize data from the Malang area. The results showed that the backpropagation algorithm produced an MSE value of 0.00004178.

Where when one activity enters, another activity will come, and so on which is multiprogramming. Round Robin (RR), Shortest Job First (SJF), and First In First Out (FIFO) methods are CPU scheduling algorithms that are popularly used in multiprogramming systems. These three algorithms are used to find Average Waiting Time (AWT) with different process sequences. In the Round Robin algorithm, there is Qu that affects the number of process sequences. The AWT value is obtained from the number of waiting for processes divided by the number of existing processes. The makespan value in each algorithm must be the same even though the process sequence is different depending on the arrival time. This study describes and analyzes how the RR, SJF, and FIFO algorithms work in the queuing process on the CPU (Central Processing Unit). The result of this research is an analysis that is easy to understand in the form of an interactive programming application. In the resulting application, it can be seen that the queuing process in AWT runs in stages according to the principles of the three algorithms.

Several factors cause a decrease in the production of corn plants, one of which is unhealthy plants so that their growth slows down and even makes the corn plants not bear fruit or are damaged. Therefore, a system is needed that can identify diseases in corn plants so that appropriate treatment can be carried out as early as possible to prevent severe damage to corn plants. With this research, the system can be built by utilizing machine learning in building a classification system using the Convolutional Neural Network (CNN) algorithm with a dataset of corn leaf images taken from farmers' fields in the Madura Region with four target classes namely healthy, gray leaf spot, blight, and common rust. Testing was carried out using several CNN architectural models such as SqueezeNet, AlexNet, ResNet-101, ResNet-50, and ResNet-18. The parameters used were 5 epochs with 100 iterations, a learning rate of 0.0001, using Adam optimization, and a data distribution of 70% for training data and 30% for testing data. The test results obtained in classifying corn images using the Convolutional Neural Network method with the ResNet-50 architecture provide a very good accuracy value of 95.59%.

In Indonesia, tobacco leaves are used as raw material for cigarettes which are mostly produced by cigarette companies. The quality of tobacco leaves greatly affects the quality of cigarettes, this is because the condition of tobacco leaves is influenced by several factors including pests, diseases, and climate. This study uses the Gray Level Co-Occurrence Matrix (GLCM) method for texture feature extraction, while for classification uses the K-Nearest Neighbor (KNN) method to classify the quality of tobacco leaves. The data used in this study is the image of tobacco leaves taken directly in TonDowulan Village, Plandaan District, Jombang Regency at the age of the leaves of approximately 2 months. Tobacco leaf images used were 300 images consisting of 3 classes, namely Normal, Perforated, and Withered based on the level of leaf damage. The GLCM features used are Contrast, Correlation, Energy, Homogeneity, and Entropy which will then be classified using the KNN method where before performing feature extraction the data must be processed first at the preprocessing stage. The result of the training using GLCM and K-NN feature extraction produces the highest accuracy value when the neighbor value 1, pixel distance 3, and k-fold 2 are 83.33%.

The requirements for applying for BP for residential buildings are different from those for non-residential buildings. The criteria for selecting the BP granting authority are given to each region. One of the regions, namely Sampang Regency, in selecting the granting of a non-residential BP, considered several things including the completeness of the files, building layout, designation and intensity of buildings, building architecture, land suitability, environmental impact control, and community approval. The decision to grant a Nonresidential BP which was taken into consideration in the assessment, as well as the involvement of two regional apparatus as admins and appraisers caused the decision-making process to be less efficient and lack transparency. Therefore, a decision support system is needed using the Fuzzy Analytical Network Process (FANP) method to assist the decision-making process for granting non-residential BP. The FANP method is used to determine the importance of the criteria used to determine the granting of a non-residential BP permit. Based on the results of the tests that have been carried out, the accuracy of the system obtained is 97.12%. With this decision support system, it can speed up the decision-making process for granting non-residential BP with fairly accurate results.

This raises concerns about misuse of data to irresponsible parties. To protect it, efforts were made to hide factual information on top of other information, namely steganography using the Least Significant Bit (LSB) method. This method has the advantage of a well-compressed image that is difficult to detect with the naked eye and has a fast process. In this study, the LSB method has two processes, namely the endcoding and decoding processes. The proposed method is tested and then evaluated MSE and computation time. In this research, each test uses 20 text messages and 20 images. The Text messages that were tested for insertion in images consisted of short messages, medium messages, and long messages. The text message will be inserted into the image with a small and a large image. The test results for the category of short messages inserted into thumbnails produce an average MSE value of 0.28 db, an average encoding and decoding processing time of 14 ms. The medium message category embedded in large images produces an average MSE value of 0.029 db, the average encoding and decoding time is 54ms. The long message category inserted in large images produces an average MSE value of 0.11 db, the average encoding and decoding time 1700 ms. The results of the three tests were that all text messages were successfully inserted into the images.

It has diverse applications in everyday life. One such application is the classification of diseases on corn leaves. Corn is a widely consumed staple food in Indonesia, and healthy corn plants are crucial for meeting market demands. Currently, disease identification in corn plants relies on manual checks, which are timeconsuming and less effective. This research aims to automate disease identification on corn leaves using the Support Vector Machine (SVM), K-Nearest Neighbor (K-NN) with K=2, and Stochastic Gradient Descent (SGD) algorithms. The classification process utilizes the Histogram of Oriented Gradients (HOG) feature extraction method with a dataset of corn leaf images. The classification results achieved an accuracy of 71.44%, AUC of 79.16%, precision of 70.08%, recall of 71.44%, and f1 score of 67.11%. The highest accuracy was obtained by combining HOG feature extraction with the SGD algorithm.

Tuberculosis (TB) is a prevalent lung disease that significantly contributes to mortality rates, ... more Tuberculosis (TB) is a prevalent lung disease that significantly contributes to mortality rates, with an estimated 98,000 fatalities observed in Indonesia alone. TB can be classified into two categories based on its anatomical location: pulmonary, when detected in lung parenchyma tissue, and extrapulmonary, when identified in organs outside the lungs. Current diagnostic procedures necessitate numerous laboratory tests and manual assessments, which are both time-consuming and susceptible to data incompleteness, thereby potentially influencing the diagnostic outcomes. This necessitates the development of a rapid and accurate classification system for the anatomical location of TB, which could aid medical professionals in diagnosis. In this study, we propose a novel classification system that utilizes the K-Nearest Neighbors (K-NN) algorithm to handle missing data, and the Synthetic Minority Over-sampling Technique (SMOTE) for data balancing. For the classification of pulmonary and extrapulmonary TB, the study employs the Long Short-Term Memory (LSTM) method, the performance of which is compared with other models, namely Naï ve Bayes, Support Vector Machine (SVM), and Backpropagation. Although all four models demonstrated high levels of accuracy, the LSTM method outperformed the others, achieving 100% accuracy compared to Naï ve Bayes (99.4%), SVM (99.3%), and Backpropagation (99.7%). These results were obtained after implementing imputation and class balancing stages, and optimizing LSTM features such as the tanh activation function, learning rate of 0.01, 100 LSTM units, and the ADAM optimizer. The proposed system thus presents an effective solution for the rapid and accurate classification of TB based on anatomical location.

Accurate early detection remains a challenge despite prevention efforts. The primary method of detecting tuberculosis is identifying bacteria in sputum samples using a microscope. This research focuses on the use of Convolutional Neural Network (CNN) with the AlexNet, ResNet-18, ResNet-50, and VGG-16 architectures in the early detection and classification of Tuberculosis (TB) through processing images of TB patients' sputum. A dataset of sputum images was collected and processed to ensure quality and adequate representation. Each CNN model was trained using deep learning techniques on the prepared dataset. The aim of this research is to compare the performance of each model in recognizing and classifying sputum images containing Mycobacterium tuberculosis bacteria and those without TB bacteria. The research results show that AlexNet architecture outperforms ResNet-18, ResNet-50 and VGG-16 in classification accuracy of Mycobacterium tuberculosis. The best validation accuracy achieved was 93.42% with the fastest time of 5 minutes and 52 seconds using AlexNet architecture. Identifying the most appropriate AlexNet architectural model could unlock the potential for developing automated systems that efficiently identify TB, thereby enabling faster and more timely medical intervention.

Therefore, ensuring the quality of corn is crucial, and to achieve this, protection against various diseases is necessary. Consequently, there is a pressing demand for an automated method capable of early-stage disease detection and prompt action. However, detecting diseases at an early stage poses a major challenge and is of utmost importance. This research focuses on the development of a classification model for corn stalk images using Random Forest. The model generates fine and coarse features of high quality to capture discriminative, boundary, pattern, and structural information used in the classification process. This research also utilizes the LBP (Local Binary Pattern) method and Color Histogram in the feature extraction process to obtain information related to texture and distinguishing patterns, that are employed in the classification process. Furthermore, the proposed model is evaluated using the corn plant image dataset, which was directly captured by the researcher in Madura, and consists of 3,000 data. The result of this research shows that the utilization of the proposed method can classify and identifying diseases in new data of digital images of corn stalks with an accuracy rate of 99.05%.

This disease is one of the contributors to high mortality cases, especially in Indonesia. Based on its anatomical location, tuberculosis is divided into two classes, namely pulmonary for tuberculosis detected in lung parenchymal tissue and extrapulmonary for tuberculosis detected in organs other than the lungs. Detecting the location of the infection in the lungs requires some analysis of laboratory results for the triggering parameters where the analysis process is still done manually, so it takes longer, and because the input process is still done manually, patient data which causes the possibility of human error to be very high. Therefore, the solution offered and the aim of this study is the ease of patient diagnosis in determining the classification of TB disease. The method used in this study is k-prototype imputation to repair missing values that have different data types, then for tuberculosis data classification methods 2 ROCHMAN, MISWANTO, SUPRAJITNO, KAMILAH, RACHMAD, SANTOSA and medical record data processing using the Random Forest, Support Vector Machine, and Backpropagation methods. Of the three classification methods proposed in this study, all three have an excellent level of accuracy. However, the Random Forest method performs more than other methods, reaching 98.8%.

The location of the State of Indonesia itself is on the equator which makes the land fertile and suitable as agricultural land. To increase agricultural productivity, the role of farmer groups is needed. Farmer groups with a high class have the opportunity to produce high productivity as well. Farmer group classes are divided into four, namely beginner, advanced, intermediate, main. To determine the class of each farmer group, it is necessary to select from the Department of Agriculture with assessment indicators, namely planning, organizing, implementing activities, evaluating and reporting as well as leadership. With so many indicators used, the Fuzzy Analytic Hierarchy Process method was chosen as the weighting and checking of weight consistency. The results of this study are a system that can measure the performance of farmer groups based on existing criteria and produce a final score which will be a benchmark in determining the class of the farmer group to be beginner, advanced, intermediate and primary. Out of a total of 131 farmer groups, 5.3% were in the beginner class, 26.7% in the advanced class, 66.4% in the middle class and 1.5% in the main class. This system also produces a fairly high accuracy value of 94.65%.

Caused by the bacterium Mycobacterium tuberculosis, TB can be fatal without proper treatment. Accurate early identification is challenging, despite prevention efforts being made. The primary method for detecting TB is by identifying bacteria in sputum samples using a microscope, but there are weaknesses such as varying interpretations and inconsistent image quality. Convolutional Neural Networks (CNN) have shown potential in improving the accuracy of identifying TB bacteria in microscopic images. This study compares the performance of two CNN architectures, ResNet101V2 and ResNet152V2, in identifying TB bacteria in microscopic images. ResNet152V2 shows better results with an accuracy of 8 3.86%, precision of 100.00%, recall of 66.39%, and an F1-score of 80.00%. Despite requiring longer computational time, efficiency remains high, demonstrating strong potential for medical applications. Future research can explore variations in architecture and parameters for even more optimal results.

Given the constraints that Small and Medium Enterprises (SMEs) face with regard to limited infrastructure, operational expenditures, and IT resources, these enterprises can derive substantial benefits from the SaaS offerings furnished by Google Apps to enhance their operational efficiency. In this study, we employ the Agile Software Development Life Cycle (ASDLC) process stages to systematically construct Supply Chain Management applications tailored to SMEs, harnessing the diverse array of SaaS functionalities provided by Google Apps. To measure the quality of development process, we present the performance metrics through the examination of various Software Quality (SQA) and also form the quality of application outcome use Technology Acceptance Model (TAM) variables. This assessment takes into account the utilization of the manifold SaaS component features offered by Google Apps within the ASDLC framework where it has resulting in exceptionally high quality and satisfactory values, making it suitable for testing and implementation for SMEs.

Tuberculosis is a directly communicable disease caused by the tuberculosis bacterium (Mycobacterium Tuberculosis). Tuberculosis bacteria can be transmitted through physical contact, the air, the sputum of patients, and so on. Currently, many people are unaware of the early symptoms and dangers of tuberculosis, so an expert system is needed to diagnose tuberculosis early and provide dietary recommendations that can help expedite patient treatment. The aim of this research is to find out early whether a patient suffers from tuberculosis using the Fuzzy Sugeno method and can recommend healthy food patterns for sufferers using the healthy Naive Bayes method which can help. In this disease diagnosis expert system, the Fuzzy Sugeno method is used to make decisions by answering questions related to symptoms. Additionally, to ensure that patients have good nutritional status, dietary recommendations are provided using the Naive Bayes method to tailor diets according to the nutritional needs of tuberculosis patients. There are 280 data on tuberculosis which is divided into pulmonary, Lymphadenitis and Enteritis tuberculosis. Based on the test results, the total number of correct data was 239 data and the number of incorrect data was 41 data, using the Fuzzy Sugeno method for disease diagnosis resulted in an accuracy rate of 85.35%. Meanwhile, the test results on food recommendations used the Naive Bayes method with the highest level of accuracy, namely 89.28% with split data testing cross validation at k=3.

kerja perusahaan. Salah satu proses yang sangat penting dalam Departemen Sumber Daya Manusia
(SDM) suatu perusahaan atau badan yang promosi Jabatan. Secara umum, promosi itu diberikan
pada bos rekomendasi atau unit kerja masing-masing berdasarkan pekerjaan lama, penilaian kinerja
dan penilaian perilaku karyawan dalam melaksanakan tugasnya. Untuk itu maka diperlukan penilaian
karyawan. Pengolahan data yang dapat membantu memfasilitasi pengawas dan departemen sumber
daya manusia untuk mengambil keputusan yang berkaitan dengan promosi jabataan. Saat ini
pengolahan data penilaian karyawan perusahaan masih dilakukan dengan komputerisasi excel,
sehingga semakin besar risiko kesalahan memasukkan mengingat jumlah karyawan sangat banyak
dan dan dibutuhkan waktu yang relatif lama. Hal ini juga masih sering membingungkan informasi
mengenai pergerakan pembentukan karyawan. Metode yang digunakan dalam menentukan promosi
Promosi ini Simple Additive Weight (SAW). Di mana metode ini adalah metode penghitungan
tertimbang atau metode yang menyediakan kriteria tertentu yang berbobot sehingga setiap nilai
jumlah dari bobot dari hasil yang diperoleh akan menjadi keputusan akhir. Dilihat dari aspek
manajerial penilaian dapat dikembangkan dengan kriteria lain sesuai dengan kebutuhan perusahaan.
Perhitungan menggunakan Simple Additive Weighting, dengan mengacu pada kriteria pekerjaan,
evaluasi kinerja, dan penilaian perilaku karyawan, kemudian memilih seorang karyawan yang akan
mendapatkan promosi.

Oleh karena itu, kebersihan merupakan tanggung jawab kita. Ajakan dan peringatan untuk menjaga kebersihan seringkali dijumpai baik di baleho, selebaran maupun di tempel di tempat-tempat umum lainnya, terutama ajakan setiap orang untuk membuang sampah pada tempatnya menurut jenis pewadahannya. Namun, berdasarkan survey dilapangan, masih kurangnya kesadaran orang-orang akan kebersihan lingkungan. Oleh karena itu perlunya edukasi akan pengenalan sampah sejak dini oleh anak-anak. Pada penelitian ini mengembangkan aplikasi pengenalan sampah dalam bentuk game berbasis 3D. Tujuan dari penelitian ini akan pengembangan aplikasi ini adalah agar anak-anak mendapat pengetahuan akan sorting trash berbasis android. Metode yang digunakan pada penelitian ini adalah Game Development Life Cycle (GDLC). Berdasarakan hasil ujicoba kepada anak-anak dengan 21 responden didapatkan respon termotivasi sebesar 86% akan kemampuan aplikasi ini dapat memberikan pengetahuan akan memilah sampah daur ulangnya dalam bentuk game.
