Abstract

Proses pembelajaran daring menjadi hambatan tersendiri dalam bidang pendidikan, terlebih untuk pendidikan wajib yang harus dilakukan secara bertatap muka langsung antara pengajar dan pelajar. Di luar faktor permasalahan eksternal, permasalahan internal perlu diselesaikan terlebih dahulu, yaitu media pembelajaran. Salah satu platform digital yang tersedia sebagai media pembelajaran untuk menunjang pembelajaran secara daring adalah Google Classroom. Aplikasi Google Classroom berbasis web yang berbentuk pembelajaran asynchronous atau dapat dikatakan pemberian materi ajar dilakukan secara tidak langsung. Walaupun sebuah media daring sudah tersedia, masih ada yang belum mengenal atau memahami penggunaan aplikasi Google Classroom sebagai media ajar mereka. Oleh karena itu, kami mengadakan pengabdian masyarakat berupa pelatihan tentang penggunaan aplikasi Google Classroom bagi guru-guru di Pondok Pesantren Miftahul Ulum Al-Islamy, yang berada di Bangkalan, Madura. Selain itu, tim pengabdi juga melakukan pendampingan bagi guru-guru dalam mempraktikkan penggunaan Google Classroom sesuai dengan mata pelajaran yang diajar. Berdasarkan hasil survei, sebanyak 91% dari total peserta pelatihan menyebutkan bahwa pelatihan ini dapat meningkatkan pengetahuan dan kemampuan secara softskill dan hardskill para guru.

Abstract

The framework application in the first phase of the Human Resources Information System (HRIS) development at X Company, which is a mining company, has so far been considered to have encountered many problems, with bugs and defects frequently being found that occurred when the project was deployed to a production environment. This happens due to frequent changes in project requirements in the middle of the development process, so many features become less relevant to business systems. So making decisions quickly and precisely before the first phase ends is necessary. The Rapid Evidence Assessment (REA) method was taken because it is a rapid review, which only a few weeks can decide based on field objective evidence. The use of a questionnaire involving project members was compared with the literature review results, namely that five aspects affected the time to develop: organizational aspects, process aspects, project aspects, people aspects, and technical aspects. The Scrum framework is a framework that is much more relevant to the current project conditions, with 3.6-point results and 3.1 points for the waterfall.

Abstract

Purpose: Acute Lymphoblastic Leukemia (ALL) Detection with microscopic blood images can use a deep learning-based object detection model to localize and classify ALL cell subtypes. Previous studies only performed single cell-based detection objects or binary classification with leukemia and normal classes. Detection of ALL subtypes is crucial to support early diagnosis and treatment. Therefore, an object detection model is needed to detect ALL subtypes in multi-cell blood microscopic images.Methods: This study focuses on detecting the ALL subtype using YOLOV4 with a modified neck using Cross Stage Partial Network (CSPNet) and GhostNet. CSPNet is combined with Spatial Pyramid Pooling (SPP) to become SPPCSP to get various features map before the YOLOv4 final layer. Ghostnet was used to reduce the computation time of the modified YOLOV4 neck.Result: Experimental results show that YOLOv4 SPPCSP outperformed the recall value of 14.6%, the value of mAP@.5 0.8%, and reduced the computation time by 4.7 ms compared to the original YOLOv4.Novelty: The combination of CSPNet and GhostNet for YOLOV4 neck modification can increase the variety of features map and reduce computing time compared to the Original YOLOv4.

Abstract

Under extreme conditions postmortem, dental radiography examinations can play an essential role in individual identification. In forensic odontology, individual identification traditionally compares antemortem dental records radiographs with those obtained on postmortem examination. As such, these traditional methods are vulnerable to oversights or mistakes in the individual identification of unidentified bodies. Digital technology can develop forensic odontology well. An automatic individual identification system is needed to support the forensic odontology process more easily and quickly because there are still opportunities to be created. We aimed to review the complete range of recent developments in identifying individuals from panoramic radiographs. We study methods in gender identification, age estimation, radiographic segmentation, performance analysis, and promising future directions.

Abstract

Feature location is a technique for determining source code that implements specific features in software. It developed to help minimize effort on program comprehension. The main challenge of feature location research is how to bridge the gap between abstract keywords in use cases and detail in source code. The use case scenarios are software requirements artifacts that state the input, logic, rules, actor, and output of a function in the software. The sentence on use case scenario is sometimes described another sentence in other use case scenario. This study contributes to creating expansion queries in feature locations by finding the relationship between use case scenarios. The relationships include inner association, outer association and intratoken association. The research employs latent Dirichlet allocation (LDA) to create model topics on source code. Query expansion using inner, outer and intratoken was tested for finding feature locations on a Java-based open-source project. The best precision rate was 50%. The best recall was 100%, which was found in several use case scenarios implemented in a few files. The best average precision rate was 16.7%, which was found in inner association experiments. The best average recall rate was 68.3%, which was found in all compound association experiments.

Abstract

Recommendation of active or productive experts is indispensable in supporting collaborations. Activities of publication and citation indicate expert productivity. An expert can be inferred to have an interest in a subject through productivity in that particular topic. Since an expert can change interests over time, the contribution of this paper is a Discrete Choice Model (DCM) based on topic productivities to predict the primary interests of the experts. DCM uses features extracted from bibliographic data of citation relation and title-abstract texts. Before extracting productivity features and dynamicity features to represent interest changes, title clustering with KMeans++ is used to identify research topics. There are six productivity features and five dynamicity values for each productivity feature to demonstrate the expert behavior. Therefore, a clustered topic as a research interest is represented as an expert choice with 30 extracted features in the proposed method. The experiments used multinomial logistic regression for DCM and a log-likelihood indicator for the fitted models of the features. The resulted DCM models showed that productive behavior of the experts by doing many publications and receiving many citations effected to the precision of topic prediction by 80%. Some features were better for predicting primary interests of the expert. It was demonstrated with a lower precision value of 60% by using features that represent the expert behavior of only doing publication or only getting citation.

Abstract

High balance value of software fault prediction can help in conducting test effort, saving test costs, saving test resources, and improving software quality. Balance values in software fault prediction need to be considered, as in most cases, the class distribution of true and false in the software fault data set tends to be unbalanced. The balance value is obtained from trade-off between probability detection (pd) and probability false alarm (pf). Previous researchers had proposed Cluster-Based Classification (CBC) method which was integrated with Entropy-Based Discretization (EBD). However, predictive models with irrelevant and redundant features in data sets can decrease balance value. This study proposes improvement of software fault prediction outcomes on CBC by integrating feature selection methods. Some feature selection methods are integrated with CBC, i.e. Information Gain (IG), Gain Ration (GR), One-R (OR), Relief-F (RFF), and Symmetric Uncertainty (SU). The result shows that combination of CBC with IG gives best average balance value, compared to other feature selection methods used in this research. Using five NASA public MDP data sets, the combination of IG and CBC generates 63.91% average of balance, while CBC method without feature selection produce 54.79% average of balance. It shows that IG can increase CBC balance average by 9.12%.

Abstract

Segmentation and overlapped cells separation are important phases in microscopic image processing of breast cancer, because the accuracy of overlapped cells separation result determines the accuracy of breast cancer cell calculation. The amount of breast cancer cells is considered by doctor in determining the action towards patients. Two of the most common topics discussed in previous studies are the problem of increasing the accuracy of overlapped cancer cell separation result by calculating the number of cancer cell and over-segmentation problem. Compared to watershed method, clustering method produces higher accuracy in separating overlapped cancer cells. In this paper, a combination of Spatial Fuzzy C-Means (SFCM) and Rapid Region Merging (RRM) method is proposed to separate the overlapped cells and handling the over-segmentation problem. The input image of overlapped cells separation phase is the result of breast cancer cell identification by Gram-Schmidt (GS) method, while the clustered cancer cells are overlapped cancer cells which are detected based on the area of geometric feature. 40 microscopic breast cancer cells image of benign and malignant type is used as the datasets. The average value of Mean Square Error (MSE) for cell identification is 0.07 and the average accuracy of overlapped cells separation using SFCM and RRM is 78.41%.

Abstract

Component Normalized Generalized Gradient Vector Flow Snake (CNGGVFS) method is the development of Gradient Vector Flow Snake (GVFS) method as an external force algorithm for active contour (snake) that can be used to get the contour of nucleus and cytoplasm of cervical smear image. However, CNGGVFS using a conventional calculation of edge map such as Sobel can not detect the nucleus area correctly in single cell cervical smear image segmentation. In this study, an external force algorithm in snake that uses Radiating Edge Map (REM) calculation to search the edge map in CNGGVFS, called as Radiating Component Normalized Generalized Gradient Vector Flow Snake (RCNGGVFS), is proposed. RCNGGVFS is used to get the contour of nucleus and cytoplasm of single cervical smear image. There are three main stages in this study, which are: pre-processing, initial segmentation, and contour segmentation. Experiments are conducted on Herlev data-set. The proposed method is compared with other methods in previous research in single cell cervical smear image segmentation. The experiment results show that the proposed method can detect the nucleus area correctly better than Radiating GVFS & Fuzzy C-Means (FCM) and Radiating GVFS & K-means. The average value of accuracy and Zijdenbos similarity index (ZSI) for nucleus segmentation is 95.34% and 88.06%. Then, the average value of accuracy and ZSI for cytoplasm segmentation is 83.48% and 87.16%. The evaluations show the proposed method can be used as a segmentation process of cervical smear image on automatic identification of cervical cancer.

Abstract

One method of optimization that can be used for clustering is Ant Colony Optimization (ACO). This method is good in data clustering, but has disadvantage in terms of time and quality or solution convergence. In this study, ACO-based Pattern Reduction Enhanced Ant Colony Optimization (PREACO) method with a gaussian kernel function is proposed. First, it sets up initial solution. Second, the magnitude of pheromone is calculated to find the centroid randomly. With the initialized solution, the weight of the solution is calculated and the center of cluster is revised. The solution will be evaluated through a gaussian kernel functions. Function 'pattern enhanced reduction' is useful to ensure maximum value of pheromone update. Those steps will be conducted repeatedly until the best solution is chosen. Tests are performed on multiple datasets, with three test scenarios. The first test is carried out to get the right combination of parameters. Second, the error rate measurement and similarity data using Sum of Squared Errors is done. Third, level of accuracy of the methods ACO, ACO with the kernel, PREACO, and PREACO with the kernel is compared. The test results show that the proposed method has a higher accuracy rate of 99.8% for synthetic data, 93.8% for wine data than other methods. But it has a lower accuracy by 88.7% compared to the ACO.
