Investigasi kecelakaan penerbangan di Indonesia pada tahun 2010 sampai 2016 sebesar 212 investigasi. Hal tersebut dapat dihindari apabila ada sistem penerbangan yang dapat memastikan penerbangan berjalan aman, seperti sistem lalu lintas udara yang dapat mendeteksi apabila pesawat bergerak menuju ke arah yang salah. Penelitian ini bertujuan untuk mengelompokkan rute penerbangan pada data Automatic Dependent Surveillance-Broadcast menggunakan metode clustering untuk mendapatkan similaritas rute penerbangan. Penulis mengusulkan metode particle swarm optimization untuk mengoptimalkan metode k-mean

Identifying road accident blackspots is an effective strategy for reducing accidents. The application of this method in rural areas is different from highway and urban roads as the latter two have complete geographic information. This paper presents (1) a novel segmentation method using grid clustering and K-MEDOIDS to study the spatial patterns of road accidents in rural roads, (2) a clustering methodology using principal component analysis (PCA) and improved K-means to create recognition of road accident blackspots based on segmented results, and (3) using accidents causes in police report t

<p>Online business and marketing are becoming popular now a day due to the wide variety of products available from multiple vendors in online. One of the major challenges of e-business merchants is predicting the buying and selling patterns of online customers. Global level competition is another challenge faced by online merchants due to the lowest prices and offers provided by multiple sellers for the same or similar product. Hence, the development of an efficient web mining framework to analyze and predict buyer&rsquo;s interest based on the browsing history will be a great suppor

The ANFIS algorithm is a technique in data mining that can be used for the data classification process. The ANFIS algorithm still has weaknesses, especially in determining the initial parameters for the network training process. Thus, an additional algorithm or modification is needed for the determination of these parameters. In this study, a clustering method will be proposed, namely K-Medoids Clustering as an additional method to the ANFIS algorithm. Basically, the ANFIS algorithm uses the FCM (Fuzzy C-Means Clustering) algorithm for the initial initialization of network parameters. The use

The traditional health indicator (HI) construction method of electric equipment devices in microgrid networks, such as bearings that require different time-frequency domain indicators, needs several models to combine. Therefore, it is necessary to manually select appropriate and sensitive models, such as time-frequency domain indicators and multimodel fusion, to build HIs in multiple steps, which is more complicated because sensitivity characteristics and suitable models are more representatives of bearing degradation trends. In this paper, we use the stacked denoising autoencoder (SDAE) model

Stunting has been widely known as the highest case of malnutrition suffered by toddlers in the world and has a bad impact on children's future. In 2018, Indonesia was ranked the 31st highest stunting in the world and ranked 4th in Southeast Asia. About 30.8% (roughly 3 out of 10) of children under 5 years suffer from stunting in Indonesia. To support the government policy making in handling stunting, it is undoubtedly necessary to classify the levels of stunting handling in regions in Indonesia.

Stunting is a serious problem for the health of children under five. The lack of quality of life for toddlers is one of the causes of the current high prevalence of stunting. East Nusa Tenggara ranks second with the highest prevalence of stunting in Indonesia in 2023. This high rate is triggered by several factors, such as health, socio-economics and environment. In terms of the environment, remote sensing technology can be utilised as a supporting tool in monitoring the incidence of stunting in the region. This study aims to map districts/cities in East Nusa Tenggara based on the incidence of
