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.

This research aims to produce a valid and reliable Mathematics Assessment Instrument in the form of HOTS test question Based on Aceh Local Wisdom and to describe the quality of HOTS test question to measure higher order thinking skill of Grade VI elementary school students. This research was a research and development adapted from research development of formative research Tessmer type namely the preliminary and formation evaluation stage consist of self evaluation, prototyping (expert review, one-to-one, and small group), and field test. The subjects on one to one were 3 grade VI students of SDN Peunaga Cut Ujong West Aceh, the subjects in small group were 6 grade VI students of SDN Peunaga Cut Ujong West Aceh, and the subjects in the field test were 30 grade VI students of Peureumee West Aceh. The research results show that HOTS assessment instrument Aceh Local Wisdom Based in the form of test questions consisting of 15 essay question items from the material aspect, construction, and language is stated valid and feasible to be used. The instrument has reliability coefficient in the amount of 0,85%, the difficulty level average 0,42 (medium), and distinguishing power 0,31 (accepted without revision). From the field test, the average result of students’ HOTS Aceh Local Wisdom Based is 78,08 with medium category, there are 7 students (23,33%) owning medium HOTS, 20 students (66,67%) have high HOTS, and 3 students (10%) have extremely high HOTS
This article reports a special application of Renewable Energy (RE) in solar energy source and technology, tending to assist other researchers and technologists in extending its field of application in the aim of replacing RE- instead of hydrocarbon fuel energy which causes harmful effects on the environment and climate- changes. Using of RE as an excellent approach to mitigate climate change which needs this clean energy to meet energy demand for the future and saving the environment. .Interrelation between sustainable development and –RE- in practice is still limited in knowledge and application. RE technologies projects have been started to facilitate and increase the utilization of RE resources. Using solar energy in water pumping in our work will incorporate with other activities in the application. We used a water pump using direct solar energy to left water up to 1m, 10m, and 20m heads and to determine the flow rates in those cases. The experiment took place in Karbala –city. The results are found in the text
