Abstract -
Data mining is extracting knowledge from very large data so that it produces useful information (Vaidya 2004). Currently data mining is not only for information gathering, but is used to recognize patterns and recognize specific characters (Neel 2011; Zaki and Meira 2013). The computational technique used is the Rule Mining Association (ARM) method, ARM can be used to determine the relationship between stocks (Agrawal et al. 1993; Lu et al. 2000). Apriori algorithm is a method to find the relationship pattern between one or more items in a dataset. This study aims to determine the minimum support value and confidence value in the ten banks listed on the IDX (Indonesia Stock Exchange) and able to select any stocks that are considered profitable. So as to make it easier for investors to decide what stocks are worth buying.

Abstract -
The LoRa (Long Range) defines the physical layer modulation technique that offers a longer range communication link than other challenging technologies, while LoRaWAN is the communication protocol for the network defined by data link (MAC) protocol and its system architecture. LoRaWAN is designed to optimize a Long Range Low Power Wide Area Network (LPWAN) for battery lifetime, capacity, range, and cost. Its concerns on the necessities of the web of things, as a bi-directional communication, mobility and localization services securely and efficiently. In mainly the unlicensed frequencies, it uses direct sequence modulation held in reserve for Industrial, Scientific, and Medical (ISM), for example in Europe (868 MHz) and the United States ranged from (902 MHz to 928 MHz). Network operators can deploy networks without the costly load of frequency licensing. The LoRa modulation is established on the integration of Chirp Spread Spectrum (CSS) which keeps the low power features as Frequency Shift Keying (FSK) modulation and enlarges the link range with Forward error correction (FEC) used for controlling errors in transmission channels. Both of them are essential for modulation. Having different chirp rates is a dominant feature that gives LoRa the ability to demodulate various orthogonal and simultaneous signals at the samilar range of frequency. LoRa Transceiver model is implemented using Matlab - Simulink with fundamental components to demonstrate how reliable elaborate modulation schemes can be built. The paper consists of ….. sections in addition to references. A brief summary about the contents of sections is presented as follow: Section I provides a brief introduction about LPWAN. Section II presents LoRaWAN architecture. Section III describes how LoRaWAN works. Section IV presents implementation of LoRaWAN. Section V presents Challenges and Obstacles. Section VI presents Market Status. Section VII presents LoRaWAN simulation. Section VIII presents the results. Section IX presents the comparison. Section X presents the the conclusion and future work. Finally, a list of references used as background of the paper is presented at the end of the proposal.

Abstract -
Quality is not only crucial to the survival and success of software system but also a prime concern of software development. Therefore, Delivering the best software quality for a product is a challenging task for a software development organization. The overall software quality depends on various factors, like reliability, performance, functionality and customer satisfaction of a product. Generally, the local software development SMEs focus only on customer satisfaction. They pursue further development or may even stop when the customer says so. Yet, the overall software quality means more than just customer satisfaction including factors like reliability, maintainability, etc. This paper takes into account the other software quality factors that also need to be focused on making sure best quality of a software product, so that the quality of software production in the industry can be improved.

Abstract -
Ontology plays an important role in semantic web development. Ontologies describe the domain specific knowledge and the relationship between the classes of the domain. In this paper, an ontology based system is proposed and developed for early child care process. To empower the progress of a nation, we have to provide productive and healthy life for a child. In this motive, the ontology based ECCD (Early Child Care and Development system) is constructed for new parents to provide responsive parenting. The system has classified the early child development into four age groups. They are Newborn (0-3months), Infant (3-12months), Toddler (1-3.5years), and Preschooler (3.5-5years). This ontology based system describes child development, Healthy foods habits, Risks, Good parenting recommendations and Immunization reminder based on their child personal preferences. In this paper, an ontology based system is developed for an early child care development (ECCD) domain to discover knowledge using protégé tool. Discovered knowledge is extracted using SPARQL. Developed ontology is integrated with .net API system. The Concept of Pattern Warehouse is introduced in ECCD ontological system to reduce massive storage. To enhance the retrieval efficiency, decision making and response time pattern warehouse is used in this paper instead of data warehouse. Finally, Response time of ECCD system using Pattern Warehouse and Data warehouse are compared.
