Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Linear programming is one of the operation research techniques to optimize certain cases. In terms of the environment, one application of programming is the case of the disposal of industrial waste into the rivers. This programming is a tool for making waste disposal decisions by considering the interests of many parties. In this linear programming, industrial interests become "objective functions", namely "Minimize the amount of reduced pollution load" with 28 equations as constraints including ten constraints related to stream standards, nine constraints related to effluent standards, and nine constraints related to the efficiency of wastewater treatment plants. The results of linear programming modeling show optimal conditions, i.e. the level of wastewater treatment that must be done by each industry before being discharged into the river so that the river is not polluted
In the 21st century, there are many farmers and rural area residents still facing poor irrigation and livestock watering system due to the high cost of electricity and lack of power supply. To solve this problem, an irrigation system using solar power with integrated remote communication system is proposed to meet these needs that are versatile, cost-efficient, and both financially and environmentally sustainable. A portable solar operated water pump is a device uses for irrigation system such as watering plantation and for daily household activities. The main components for this device are solar panel, electrical water pump, and microcontroller where all these components are connected with each other and can be controlled through a communication system. In this paper, the fabrication process and integration of communication system using a global system of mobile communication (GSM) in development of this device is explained in detail. From the performance evaluation, this device could supply about 3 liters per minute for a farm with area of 300 to 400 m2. In agricultural activity, the farmer does not need to be physically at the farm to operate this device, and the watering process still can be done, and this can avoid the crops from dying. This study could be a great potential in the smart agricultural activities especially in managing irrigation systems
