The term Industrial 4.0 refers to the idea about fourth industrial revolution. In order to realize Industry 4.0, academic involvement is required in the form of research. This article aims to define the aspects and future direction of research related to Industry 4.0. Literature review of various definition and concept models of Industry 4.0. was conducted to acquire the aspects. Mapping and analysis of several publications were conducted to determine the future direction of research. Publications were sorted according to research methods, aspects and type of industry. The result shows that Industry 4.0 has fourteen aspects. Based on research methods, most of the research is done through descriptive and conceptual methods. Business and technology aspects become the focus of the researchers and most of the research is done in manufacturing industry. Based on quantities, Industrial 4.0 research has experienced a significant upward trend. This article is expected to illustrate the concept, future development and research trend of Industry 4.0.Keywords: Industry 4.0; Literature Review; Research Trend

There is a lot of research that proposed PV monitoring systems based on the low-cost IoT technology. However, there is a lack of implementations in the On-grid PV systems. This research aims to fill this gap, by proposing a novel design of On-grid PV system power monitoring. The design utilizes a CT sensor, NodeMCU, MQTT, Node-RED, and Raspberry Pi. The hardware cost is affordable. SQLite is introduced to reduce the database complexity. A trial has been accomplished through a case study of 3.6 kWp On-grid PV system. The designed dashboard consists of two pages. The first page displays summary information, and the second page serves access to the historical data. Based on the test, the current readings accuracy is acceptable. The proposed design is applicable to residential On-grid PV systems in urban areas. This research may become a potential support for the public awareness of renewable energy, especially in the developing country, where financing becomes a key challenge.
