An analysis of the uncertainty value of measuring spur gear dimensions using a profile projector has been carried out. Dimensions of spur gears measured are pitch diameter, root diameter and outside diameter. The manufacture of 3 samples of spur gears was first made with a shape milling machine based on the initial technical data that had been determined. Then measurements were made with a profile projector measuring instrument for the three measuring dimensions, the best repeated measurement average was found in the root diameter measurement for the PJ01 sample of 32.4053 mm with a standard deviation of 0.0077 mm. The uncertainty method used is statistically and applies only to a series of observations. Determination of the uncertainty value is done by performing repeated measurements five times on the same sample. This method refers to ISO GUM with type A evaluation. The uncertainty value obtained for the best measurement is 0.0034 mm with an expanded uncertainty of 0.0068 mm with a 95% confidence level.

Humans have various types which are called races. The human race can be identified by many things, from the shape of the body to the color of the body. Of the many ways to identify the human race, the author also thinks whether a computer can identify the human race based on skin color. Nowadays, computers have developed in such a way that there are many possibilities that computers can also do this.

ABSTRACT Background: Diet is aiming to lose weight can be done in various ways.During the adolescent anxiety problems against weight loss arising more happens than the other.The physical changes that occur in particular weight and body shape increases the risk of someone worrying about her weight. Purpose: This research was conducted aiming to know the behavior of young women about diet in SMA Negeri 5 Pekanbaru. Method: This research is quantitative type with anlitik design with coss sectional approach. This type of research is quantitative and deskriftif design. The population of this research as much as 444 people with 82 samples of respondents with the method of sampling Simple Random Sampling using univariate analysis.This research instrument using questionnaires and engineering research with primary data. Results: Based on the results of research that young women in SMA Negeri 5 Pekanbaru knowledgeable low as much as 42 respondents (51%), being negative as much as 43 respondents (52%), and the actions that go on a diet as much as 58 respondents (71%). Conclusion: For the respondent is expected to be more positive about the diet, and can do the diet properly and healthily.   Keywords: Behavior, Young Women, Diet   ABSTRAK Latar Belakang: Diet merupakan usaha yang bertujuan untuk menurunkan berat badan yang dapat dilakukan dengan berbagai cara.

Mainstream work activities that are generally carried out in rigid office spaces sometimes cause boredom for workers. Variations in ways and places of working need to be accommodated to avoid boredom. BeeHive Co-Working was built with the aim of providing a new place to work and socialize which is expected to provide enthusiasm in carrying out work activities. The design method applied is through a process that begins with the problem of how to create a flexible, relaxed, and unpressured work environment. The idea of Co-Working design is proposed to answer the initial problem. Green Architecture theme is proposed as the main theme of BeeHive Co-Working design. The concept of Green Architecture used in this design takes the main focus as a building that is energy efficient, minimizes expenses and increases the added value of the building. The position of the building in green architecture is related to (1) being able to adapt to solar circulation and wind direction, (2) extending from east to west, blocking solar radiation on transparent walls, (3) reducing heat transmission from massive walls exposed to direct solar radiation. The design of BeeHive Co-Working, which applies the concept of Green Architecture, is realized in the form of a modern design transformed from a rectangular mass form with a front view that uses an additional honeycomb-shaped facade. BeeHive Co-Working facilities that support the function of casual work are accommodated by the provision of furniture designed for the convenience of working while relaxing. The commercial function is supported by the provision of café shop facilities. This design is expected to be a place for workers to restore energy from the fatigue of busy work activities.  

This paper focuses on unlocking the creative potential of architecture students through an exploration of the Four C model of creativity. This model extends the traditional understanding of creativity and offers a comprehensive framework for fostering innovation in architecture. It introduces "mini-c" and "Pro-c" dimensions, highlighting creativity within the learning process and the attainment of professional expertise. Architecture demands a blend of technical skills and artistic expression for effective communication of ideas. However, nurturing creative thinking among architecture students faces challenges, including fear of experimentation and traditional teaching methods. To address these obstacles, the paper suggests integrating problem-based learning (PBL) and mind mapping techniques. PBL encourages collaboration and critical thinking, while mind mapping stimulates visual and associative thinking, aiding idea generation and organization. Additionally, the role of technology in architecture education is explored, emphasizing the benefits of mixed learning environments that enhance collaboration and creativity. Embracing technology readiness equips students with tools to tackle real-world challenges and create innovative designs. In conclusion, this paper underscores the importance of creative thinking in architectural design and its implications for the discipline's future. By adopting the Four C model, implementing PBL with mind mapping, and leveraging technology, educators can revolutionize architecture education, nurturing a new generation of architects prepared to shape the evolving world with imaginative and visionary designs.
