PRODUCT CLUSTERING ANALYSIS ON THE MARKETPLACE USING K-MEANS APPROACH (CASE STUDY: SHOPEE)
The business world has experienced a paradigm shift towards a more modern concept. Many business processes are carried out through the internet or commonly known as e-commerce, by utilizing a platform known as Marketplace. One of the marketplaces that are quite well-known and in great demand in Indonesia is Shopee. The high online shopping activity in the current marketplace indirectly encourages business actors to understand the online market. However, one of the obstacles that are quite often faced by sellers, especially new sellers who are starting to enter the digital realm, is the emergence of confusion in the selection of products to be sold due to a lack of information regarding the demand for what products are in demand in the market.The process of searching for information related to the demand for products of interest is carried out through clustering analysis to find out the groups of products that are of interest to those that are less attractive to the public. The data used is product data from 6 categories in the Shopee market which was taken using web scraping techniques. The clustering processes used the K-means approach by determining the number of K and the optimal center point through the calculation of Sum Square Error (SSE) by looking at the elbow graph. The final results show the optimal number of K clusters that are different in each category, namely in category women’s clothing, men’s clothing, and electronics are at K=4 then for products in the category of Muslim fashion, care & beauty and household appliances are at K=3. Based on the validation results using the Davies Bouldin Index, values were obtained in6 categories, namely 0.391, 0.438, 0.414, 0.357, 0.387, and 0.377, which means that the cluster structure and the level of information formed in each category using the K-Means method is quite good
Software Development Methods in the Internet of Things
Part 1: Information and Communication Technology- Eurasia Conference (ICT-EurAsia)International audienceIn the Internet of Things, billions of networked and software- driven devices will be connected to the Internet. They can communicate and cooperate with each other to function as a composite system. This paper proposes the AMG (abstract, model and generate) method for the development of such composite systems. With AMG, the development of software application can be done in an automatic manner, and therefore reducing the cost and develpment time. The method has been prototyped and tested with use cases
Pengembangan Media Pembelajaran m-learning Menggunakan SMIL
SMIL merupakan bahasa yang digunakan untuk mempresentasikan audiovisual secara interaktif. Digunakan secara khusus untuk presentasi multimedia dan merupakan integrasi antara audio dan videa dengan gambar, teks, atau sembaran tipe multimedia yang lain. SMIL dikembangkan dengan didasarkan pada XML yang memungkinkan authos untuk menampilkan presentasi multimedia interaktif. Penelitian ini mencoba untuk mengembangkan media pembelajaran berbasis multimedia yang bersifat mobile menggunakan SMIL.
Hasil penelitian menunjukkan akses materi pembelajaran menggunakan piranti telepon selular masih mengalami kelemahan dalam hal banyaknya slide tampilan yang dapat diakses oleh karena keterbatasan memori. Akan tetapi, akses materi pembelajaran yang sama melalui web menggunakan komputer tidak ada kendala

Model-driven and Compositional Service Creation in the Internet of Services
Doktorgradsavhandling i informasjons- og kommunikasjonsteknologi, Universitetet i Agder, Grimstad, 2012In the Future Internet, billions of devices will be connected to the Internet. Devices
at any levels of hierarchy provide software functionality that can be used by
others. We can call the device’s functionality a service, which in turn, introduces
the concept of the Internet of Services. From the software developer perspectives,
a new service can be created by utilizing services in the Internet of Services. An
important issue of the creation of such service-based application is regarding their
deployment method on personalized and embedded devices. For each device with
different capability and configuration, different tailored code is required. For this,
a flexible method and tools that support an automatic code generation for a device
with a specific capability and configuration are mandatory.
This thesis proposes PMG-pro (Present, Model, Generate and provide), a language-
independent, bottom-up and model-driven method for the service creation in
the Internet of Services. With this method, a service is created by providing the new
functionality of a service-based application as a service. By using existing service
frameworks and APIs, from a service description, PMG-pro generates an abstract
graphical service representation (service model) and source code implementing for
service invocations. Depending on the target modeling languages, different graphical
notations can be used to represent services. Similarly, different programming
languages can also be used to implement the service invocations. We call these
pairs (i.e., the service model and the source code) platform-specific models. With
these platform models, service composers use the graphical service representation
to model new service-based applications, while the machine (i.e., computer system)
uses the source code to generate code from the service-based application model.
This thesis contributes to the service engineering method that applies a modeldriven
development approach. Three main contributions are a model-driven method
for service creation, an automatic service presentation of pre-made services, and a
new method of handling device capability and configuration. With these, service
creation in the Internet of Services can be done in a rapid and automatic manner.
Service designers can create a new service by defining a model of service-based
applications using pre-made service models, while code for a specific device can be
generated automatically from the model.
The PMG-pro method has been partly prototyped and validated on various case
studies in the domain of smart homes that have produced encouraging results. The
method promotes a rapid, language-independent, and unified process of software
service development
