The world that is shifting the Industrial 4.0 era is now connected to the use of the Internet of Things (IoT) in various fields including agriculture. Increasing food demand in 2050 requires a smarter agricultural system than before. Precision Agriculture, Utilization of Drones for Agriculture, Livestock Monitoring, and Smart Greenhouses is an implementation of IoT technology for farming more efficiently and managed among various improvements in agricultural improvement. At present, the world is launching the Industrial 4.0 era, one of which is closely related to the understanding of the Internet of Things. Various views, resolutions and visions form the basis for the formation of the Definition of the Internet of Things. At the beginning, the Internet was known by the characteristics of the World Wide Web (www) which emphasized in the form of Hyper Text Markup Language (HTML) documents that were connected to each other. This concept developed into Web 2.0 which allows user interaction through social networks, forums, blogs, e-learning platforms, Content Management Systems (CMS) and so on. In the next stage, the Internet developed into Web 3.0 or better known as the Semantic Web. The ultimate goal of Web 3.0 is to make web content and services accessible to devices without human assistance. IoT takes Web 3.0 to a new level by enabling seamless connectivity anytime and anywhere by anyone and anything. This makes it possible to create new value-added services by dynamically collecting compute types of computing capabilities (sensing, communication, data collection, and actuation). The concept of the Internet Things that are based on the integration of various processes such as those related to making up network-based to solve problems. Internet of Things has the ability to change the world where life is like a more efficient industry, interconnectivity in public transportation, the concept of smart city implementation. No exception, the application of IoT technology in agriculture and plantations has a large ownership. So yes, the world of agriculture and plantations need to know and embrace the concept of the Internet of Things to be more developed than before. The world population is known to produce 9.6 billion by 2050. For sustainable agriculture, agriculture can be accelerated by embracing IoT. This is increasingly important given the challenges to the limitations of agricultural land, climate change and improving the climate of agriculture, agriculture, agriculture, agriculture, agriculture, agriculture, agriculture and agriculture. IoT-based Smart Agriculture will enable farmers to work more efficiently than reducing the amount of fertilizer used for agricultural equipment use. The efficacy of this increase will certainly increase productivity. So what is Smart Agriculture? Smart Agriculture is an efficient system that uses high technology to cultivate and manage food crops that are managed by many parties. This relatively new agricultural system is able to lift trends such as organic farming, small-scale agriculture or with certain cultures. From an environmental point of view, IoT-based smart agriculture can provide great benefits including the use of more efficient water, or input optimization and crop maintenance. As an application of Smart Agriculture can be divided into several activities, namely (a) Precision Agriculture or Precision Agriculture, (b) Agricultural Drones or Utilization of Drones for Agriculture, (c) Livestock Monitoring or Livestock Monitoring, and (d) Smart Greenhouses or Smart Greenhouses . Precision farming is everything that makes it agricultural practices are more controlled and accurate, especially in crop cultivation and livestock raising. Precision farming improves agricultural management with information technology components such as sensors, control systems, robots, autonomous tools, and automated hardware. In its application, the hardware is supported by the adoption of high-speed internet access, mobile devices, and low-cost satellites that are reliable for imaging and positioning. Precision farming is one of the most well-known forms of IoT applications in the agricultural sector. Many world companies in agriculture use this technique for efficient performance and production performance. For example, CropMetrics is a precision agriculture company that focuses on ultra-modern agronomic solutions in the management of precision irrigation. CropMetrics products and services are optimizing Variable Rate Irrigation (VRI), soil moisture probes, PRO virtual optimization and so on. The key technology from CropMetrics is maximizing profitability on agricultural irrigated land with topography or soil variability in the context of efficient water use while still being able to increase yields. On the other hand, drone technology is currently becoming a trend in agricultural practices. Since the last few years, drones or known as Unmanned Aerial Vehicles (UAVs) have begun to be implemented in plant health assessment, irrigation, plant monitoring, plant spraying, aquaculture and soil analysis. Ease of use and time savings are the main reasons why this drone technology can provide innovative changes in the agricultural industry. Not only that, the wireless IoT application is starting to be used for livestock monitoring. Data on location and health of livestock based on IoT can help farmers to identify sick animals so that they can be separated from the herd faster to prevent the spread of disease. This alternative is also able to reduce labor costs because supervision can be done with the help of electrical sensors in the farm location. The latest IoT application looks at how improved yields of agricultural crops are developed in smart greenhouses. As the name implies, smart greenhouses are designed with IoT to monitor and control climate and minimize the need for manual intervention by humans. At present, there are still many greenhouses that control conventional environmental parameters. The method was considered ineffective and instead affected the loss of production, energy and swelling labor costs. Modern IoT-based controls use electrical sensors as needed. Cloud-shaped servers can be created to access the system remotely when needed. IoT-based agriculture allows stakeholders to obtain useful real-time data. This process will cut all activities that require a certain time period and a large enough workforce on the scale of the agricultural industry. Therefore, the agricultural industry today must be aware of the potential of the IoT market for applications in the agricultural world. The use of intelligent technology can increase competition and the sustainability of the production of agricultural products. The need for an acceleration in increasing food productivity in the context of increasing the number of human populations in the world can be achieved when IoT in agriculture is embraced as a solution to the problems that hamper agricultural production such as limited land, climate change and labor shortages. Should the world of agriculture know IoT? Of course, if you don’t want to be left behind.
