<![CDATA[Delayed walking is a disorder of walking delay in the toddler aged 9-18 months. There are several indicators that cause delays in walking on children including motor, genetic and temperament. These factors are rarely understood by parents. And sometimes the delays seem to be left unchecked and that can cause its own failure. The lack of time to consult with a child specialist has resulted in such cases seeming to be left unchecked. Expert systems are built to provide knowledge to the public about the phenomena of walking delays that occur in children and the causes and solutions that will be obtained by parents. This system was built using a forward chaining method whose data reading was traced to the daily activities of toddlers. This system is designed to adapt information directly from child experts or child specialists who understand firsthand the condition of the child and delayed walking.]]>

<![CDATA[The implementation of online lectures using blended learning needs to be assessed to find out the performance activities of lecturers with students in using the learning activity management system (LAMS) feature and reward lecturers with the best performance. Based on the assessment system of the best lecturers previously have not used the right methods so that the resulting decision is still not right and not accurate. This research aims to implement the Analytical Hierarchy Process (AHP) method in the assessment process of lecturers who are the best in using LAMS. The performance of the AHP method can determine the weight value of criteria consistently and can perform a role to produce solutions in decision making. The criteria indicators used to consist of Interactive Video Teaching Materials (C1), Audio Teaching Materials (C2), URLs (C3), Forum/FBL (C4), Slide Teaching Materials (C5), Assignments (C6), Quiz (C7), Attendance (C8), and Labels (C9). The results of this study showed that the performance of the Decision Support System (DSS) using the AHP method can determine a better weight value with a consistency level of 0.080049762 from 0.1. These results presented with AHP performance can provide weighting value on each criterion and continue the multiplication process with the best lecturer assessment data to get the results of the battle. Overall these results concluded that each criterion had a degree of consistent relationship in the best lecturer assessment on LAMS.]]>

<![CDATA[Infectious diseases are common diseases and are caused by microorganisms such as viruses, bacteria, and parasites. Indicators of the spread of this disease can be seen based on the population level and the number of confirmed cases. This study aims to develop a machine learning (ML) analysis model using the K-means cluster, artificial neural network (ANN), and decision tree (DT) methods. The dataset used in this study was obtained based on the number of confirmed patients and the distribution of the population. The analysis process is divided into two stages, namely preprocessing and the classification process. The pre-processing stage aims to produce a classification pattern that can describe the level of distribution status. The classification pattern will be continued at the classification analysis stage using ANN and DT. Classification analysis gave significant results with an accuracy rate of 99.77%. The results of the classification analysis can also describe the level of knowledge distribution based on the decision tree. Overall, the contribution of this research is to develop a classification analysis model that presents the latest information and knowledge. The results of the research presented also have an impact on the control process in environmental management and public health.]]>

<![CDATA[Ground Glass Opacities (GGO) are a picture of abnormal lung conditions characterized by white or gray areas. This picture of GGO in the lungs could previously be detected based on the results of medical examinations such as Computerized Tomography (CT scan) and Magnetic Resonance Imaging (MRI) images of patients suffering from Covid-19. However, from the results of the examination, it can be seen that the CT scan and MRI images still have a noise level that is too high, causing difficulties in describing the distribution pattern of the GGO itself. The purpose of this study was to optimize the detection of GGO on MRI images using the Multipixel Interpolation technique. The detection process adopts several stages including image preprocessing, edge detection process, and gradient morphological segmentation. Image preprocessing is done to remove noise and improve the MRI input image. The edge detection process is carried out to detect lung organs automatically using the Canny method which is optimized with the multipixel interpolation technique. The final stage of the research is the segmentation process using a gradient morphology technique to see the spread of GGO in patients with Covid-19 contained in the MRI image. The results of this study present an overview of the GGO pattern with fairly good results. The results of the GGO pattern description will also measure the level of spread to see the severity of pneumonia. Based on the results presented, this research is useful as an alternative solution in the process of diagnosis and treatment of Covid-19 patients.]]>

<![CDATA[Penelitian ini bertujuan untuk memberikan informasi kepada masyarakat mengenai malnutrisi, gaya hidup atau lifestyle merupakan salah satu faktor yang ikut serta dalam mendeteksi malnutrisi. Tak jarang diantara orang tua mengabaikan hal tersebut karena dianggap biasa dan lumrah. Bahkan tak jarang juga diatara orang tua malas berkonsultasi dengan pakar perihal kondisi tersebut dikarekan berbagai macam alasan. Untuk itu diperlukan sebuah sistem yang mampu memberikan kemudahan kepada masyarakat seputar malnutrisi. Dalam penelitian ini malnutrisi lebih dikhususkan pada balita karena balita memiliki indikasi terbesar mendapatkan malnutrisi apabila asupakan makanan yang harusnya dikonsumsi oleh balita tersebut tidak tepat. Sistem pakar ini dibangun dengan menggunakan metoda hybrid yang menggabungkan antara forward chaining dengan certainty factor dalam mendapatkan kesimpulan atau konklusinya. Sistem ini dibuat dengan menyadurkan informasi langsung dari pakar.]]>
