Integrated application for automatic schedule-based distribution and monitori...journalBEEI
40% of areas in Indonesia are still using rainwater as a source for irrigation. Type of wetland rainwater always depends on weather that is currently difficult to predict. In addition, the frequency of field cultivation became limited. Irrigation water can come from a dam or a spring in the mountains. Limited water source generates the need to manage water distribution in all areas of rice fields. For every 1 hectare fields, at least 0.5 litres of water per second is needed. The imbalance between the field and the available water discharge can cause conflicts in the Community farmers manage field. The purpose of this research is to assist in the Assembly Of Farmer Water users ("Perkumpulan Petani Pemakai Air" or "P3A") manage the scheduling and controlling irrigation sluice based IoT using mobile applications. The waterfall process model applied in developing mobile applications. Every feature that is created has been tested directly using Unit tests based on the application of the system used. The test is done by observing the system inputs and outputs of the system usability scale (SUS). Tests are also carried out using Post-Study with method of the SUS.
IoT based Digital Agriculture Monitoring System and Their Impact on Optimal U...Journal For Research
Although precision agriculture has been adopted in few countries, the greenhouse based modern agriculture industry in India still needs to be modernized with the involvement of technology for better production and cost control. In this paper we proposed a multifunction model for smart agriculture based on IoT. Due to variable atmospheric circumstances these conditions sometimes may vary from place to place in large farmhouse, which makes very difficult to maintain the uniform condition at all the places in the farmhouse manually. Soil and environment properties are sensed and periodically sent to cloud network through IoT. Analysis on cloud data is done for water requirement, total production and maintaining uniform environment conditions throughout greenhouse farm. Proposed model is beneficial for increase in agricultural production and for cost control and real time monitoring of farm.
Wireless sensor network for monitoring irrigation using XBee Pro S2CjournalBEEI
Monitoring irrigation is still the problem of agriculture in Indonesia. During the dry season, the farming fields drought while in the rainy season, floods happened. Since the farm-fields located far from the urban area, it requires an automatic tool for monitoring the availability of water that can help the farmer to monitor the farm-field. Wireless sensor network is an appropriate technology used to overcome problems related to the monitoring system. This research is using a water level sensor, pump, Arduino Nano, and XBee Pro S2C in each monitoring node. The system designed within two modules, an automation irrigation module and a monitoring module, which is connected with the communication configuration of master-slaves between Xbee Pro S2C at each node. The system examined several scenarios in order to test the performance. Based on the testing result, all the performance parameters can be adequately delivered to the user and appropriated with the real condition in the farm field. The delay between nodes only takes 5-10 seconds.
WEB-BASED IRRIGATION MONITORING AND CONTROL SYSTEMijcseit
In Uganda, as well as other developing countries, the increasing population stimulates the
agricultural-related activities such as irrigation. Irrigation is basically done by humans and generally
requires exhaustive physical efforts and involves exposure to errors during irrigation. Despite the
advances in the irrigation and its wide spreading applications, irrigation remains majorly manual. Since
irrigating is a difficult process especially when irrigating a big piece of land, it is necessary to simplify the
process, thus web based system in irrigating was introduced and existing implementations have limitations
such as irrigating at wrong hours, continued wastage of water, so prevent all this, a new system that uses a
web control to remotely irrigate from a distance has been developed ,therefore main objective of this
project is to design and develop a web based irrigation monitoring and control system since it is observed
that this method is more reliable and efficient compared to the existing methods. The developed system is
able to automatically receive the moisture levels from the field, responds to the different commands sent by
the user to do the irrigation and the user is also able to switch on and off the pump.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

49. Conclusion
• Agriculture is an application-specific domain in which the
implementation of the IoT and other emerging modern
techniques and tools can provide new solutions for traditional
problems
• IoT improves the crop and water productivity, efficiency and
reduces human intervention in rice cultivation
• However, higher capital requirement and initial resistance to
new technologies at farmer level are major constraints
