Thinking styles more boradly intellectual styles refers to people’s partly fixed, relatively stable and innate preferences about information processing and handling with the tasks that they may confront (Zhang & Sternberg, 2005). Sternberg’s (1988) introduced of the theory of mental self-government, where intellectual style specifies 13 thinking styles that fall along five dimensions of mental self-government: (a) functions, (b) forms, (c) levels, (d) scopes, and (e) leanings of government as applied to individuals (Zhang, Sternberg, Rayner, 2002: 14).Hypothetico-Creative reasoning model developed by Duran (2014) can be defined skills including logical and creative thinking skills in 12 dimensions. This study, is a descriptive study based on, relational screening model among the screening models.The purpose of this study is to investigate the relationship between learning styles proposed by Sternberg (1988) and hypothetico-creative reasoning skills proposed by Duran (2014) in the context of the characteristics of left an right brains or thinking modes emphasized by Zhang (2002). The population consists of all the second grade students (N=383) in those departments in the education period 2015-2016 in English Teaching Department, Preschool Education Department, Department of Elementary Education, The Department of Computer Education and Instruction, The Department of Psychological Counseling And Guidance. It was found that students are more prone to use their right brains, that is lateralization of hepispheric specialization is thought to be in right side. Hence students perceive themselves to use Type I thinking, holistic mode of thinking styles indicating that they use right brain hence perceive themselves to be more holistic, creative and experiantial learners.

Papua and West Papua Province have the large potential of sago palm (Metroxylon sagu), however, until now the production and utilization is very low compared with its potential. This is because of most farmers in this area still use traditional method in processing sago.  The traditional method is labour intensive and time consuming process.  Sago farmers in this area still apply traditional ways to process sago starch due to the lack of processing machines. The objective of this research was to conduct field testing of sago processing  machine produced by Agroindustry Machinery Workshop of Papua University. The machines that have been tested consist of cylinder type sago rasping machine and stirrer rotary blade sago starch extraction machine. The machine’s performance under field condition was evaluated by measuring parameters (a) rasping capacity, (b) extraction capacity, (c) starch percentage, (d) starch yield and (e) starch loss in waste. Results showed that all parts of the machine are functioning properly and farmers can easily operate the machine.  The performances of the machines under field condition were (a) rasping capacity 1,159. 8 kg/hour, (b) extraction capacity 243.8 kg/hour, (c) starch percentage 38.26 %, (d) starch yield 93 kg/hour   and (e) starch loss in waste 1.03 %.   Keywords: cylinder type, field test, rasping machine, sago processing, starch percentage
