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.

Generally, the green technology has been taken for granted in terms of providing clean and cheap energy without realising the costs. However, there are many trade-offs concurrent with enabling such technology. Accordingly, this paper evaluates and compares the green energy based networks with traditional counterparts. It presents a mathematical model which helps understand-ing the different variables that are necessary to advocate the green/renewable method over tra-ditional, or vice versa. This research shows that the cost efficiency (CE) of green networks can be relatively high, about twice the traditional, that is represented by cloud radio access network (C-RAN). Based on experimental data, this research shows that green technology requires more operational caring than traditional to produce same amount of power. With variant sites, cities, countries, geographical areas and equipment’s manufacturing characteristics, the model can pre-dict the total green systems’ trade-offs in the future. By doing so, the service providers, investors or network vendors are able to re-consider and decide the shifting between both types of networks
ACS712 is a sensor to detect current. ACS712 current sensor can detect noise current or additional current. ACS712 current sensor is one of the sensors commonly used in current measurement circuits. In calibration there is an uncertainty that comes from calibration standards and calibrated devices. Analysis of uncertainty calibration ACS712 current sensor has been done with a purpose for acquired correction value, standard deviation, and uncertainty source estimation, and then the biggest source uncertainty from current measurement can be identified. The result of the analysis can be used to minimalize the possibility of appearance uncertainty source on measurement using the ACS712 current sensor. The analysis was conduct by comparing between ACS712 current sensor and clamp meter standard with a calibration certificate. ACS712 sensor test results have a significant correction when the current higher than 5A, and the temperature will increase. The biggest sources of uncertainty result from type uncertainty and expanded uncertainty
