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.

The scientist plays an essential role in making discoveries and inventions. However, human limitation and individual reasoning can obstruct the way of doing science. Knowing the systems thinking process is an essential approach to understanding how scientific products are influenced by various factors. Research on cognitive biases can help this interest in understanding these limitations among scientists. We discuss scientific activities that consider the history and philosophy of science and the sustainable future requiring creative problem solving, which can be very susceptible to cognitive biases. We also pay attention to the multilayered nature of current scientific work, where the scientist works individually and collaborates with colleagues. Thus, this paper discusses the framework of cognitive biases related to scientific work. Weighing those considerations, we construct an alternative new framework by listing the biases in scientific work. We close by recommending the validation of this framework to become a potential construct that would be helpful for further study.
Indonesia is one of the richest countries for the renewable and nonrenewable energy resources. The energy source is needed to fulfil the household, industrial and mining needs. A coal mining process particular in PT. Bukit Asam used petroleum to run the production equipment. Cat 3406 engine which used in D8R is one of the production equipment that pushing the coal in TLS (Train Loading Station). Due to the energy source of D8R is derived from diesel, the combustion processing in the combustion chamber produces exhaust gas emissions. The emissions are too dangerous for humans, hence, to analyze the exhaust gas substance is required. In this research, collecting data of diesel, biodiesel B20 and biodiesel B30 due the engine rotation at 800 rpm and 2100 rpm at each variation is carried out. The generated gas is analyzed using measured exhaust gas emissions. As the results, B30 produced lowest emissions, while the highest torque is generated by diesel. The amount of fuel consumption for diesel and biodiesel are same.
