Abstract

Manufacturing motorcycle unit in Plant 1 of PT ABC requires engine supply from Plant 2. This has some burden on the operating cost of Plant 1 and the opportunity loss as well due to delay of motor engine delivery. Based on the problem, team proposes additional engine line in Plant 1 to cut engine supply from Plant 2. Therefore, team analyzes this proposal using incremental analysis to determine whether the proposal is feasible or not by comparing before and after condition with result NPV about IDR 967 Billion and Payback Period under 1 year. By this result, team determines that this proposal is recommended to be approved by management.

Abstract

The DES encryption/decryption algorithm is quite a popular algorithm due to ease in learning. Calculations for DES using binary numbers however are very difficult, including 16 rounds required for a full encode. Teaching DES encryption manually is difficult since it requires a long time. It also requires high accuracy for the 64-bit binary numbers, the possibility of mistakes are very high. Besides, the students cannot perform self-check, whether the given task is done correctly. Application of Excel and VBA is used to facilitate observation, comparison, and understanding the DES algorithm. The result is a teaching model using DES for modern encryption.

Abstract

The term ‘vernacular’ and ‘traditional’ in architecture context actually has a root meaning which is almost the same; both have the same meaning that can be attached to one form of architecture work which is oriented on locality aspects and historiy of its existence. However, how can we distinguish the two terms? One way to find it out is to do a case study on two traditional architecture buildings: Balinese buildings and Minangkabau buildings taken as the sample study. In general, both building have two criteria: culture philosophy and adaptative modernism. Through descriptive analytical methods, the two building types were analyzed to acquire the definition of the building shapes which can be classified whether they belong to vernacular or traditional. The results show that vernacular architecture is a form of original work which is specified with the content and a very strong local and contextual philosophy proper to its time, while the traditional architectural building is a vernacular masterpiece recognized by acclamation and hereditary within a very long time.

Abstract

Children’s response towards something is different from adults’. If an architect designs the foot of a monument with a beautiful arch, a child will respond it as a slide. When an architect designs a water pool as an aesthetic element of a monument area, a child will respond with a different return, which is a place to shower/swim and play, not for aesthetic. What is this phenomenon? And how can we understand this well? This story reassures us that between adults and children have different concepts of a building or space. With a descriptive approach to literature review, this article examines some affordance-based studies. From the few studies presented, it appears that affordances are not enough to understand why kids play on an informal play space. Semiotic approach can help to better understand why children play in informal spaces.
