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.

Abstract

Cimahi is a city in West Java that owns many relics of the Dutch architectural heritage built in the early 20th century. The majority of buildings are military buildings that have a hierarchy according to the military rank, seen from the styles presented at the army's military housing. The building style has no longer presented either Indische empire style or modern colonial style. The architectural style in the transitional period at that time adapted the tropical climate of Indonesia with the visible formation of the Dutch. This paper is the result of research done by observation and a survey at the Army Military Housing, Cimahi, West Java. Data were analyzed quantitatively to analyze the number of houses and ornaments dismantled and its original form. In addition, qualitative methods are also used to analyze the demolitions done by the building occupants.

Abstract

Slum areas are likely found in many cities in Indonesia although the government through the Ministry of Public Housing have rolled several programs to alleviate its existence. One example of slum areas is found in Payakumbuh, West Sumatra, where its land are mostly owned by local traditional folks knowned as ‘ulayat land’. A huge amount of poor houses are built on rented ulayat land. Regarding to the rent status, the housing arrangement on the area faces difficulties. Therefore, this article would like to give an overview of problems in the slums arrangement in Payakumbuh as well as giving some concepts for dealing with the problems associated with such land status owned by adat.

Abstract

Pengukuran resiko manajemen proyek teknologi informasi ini bertujuan untuk mengetahui bagaimana penerapan manajemen proyek teknologi informasi (TI) berjalan pada PT MSI agar penerapannya dapat sesuai dengan tujuan bisnis yang diharapkan oleh perusahaan dan memperkirakan resiko-resiko apa yang mungkin terjadi. Metode penelitian yang digunakan adalah studi kasus di mana teknik pengumpulan data meliputi studi kepustakaan serta studi lapangan yang meliputi wawancara, kuesioner, dan studi dokumentasi. Pendekatan untuk melakukan pengukuran resiko teknologi informasi pada PT MSI adalah PMBOK (Project Management Body Of Knowledge). Hasil yang dicapai adalah ditemukannya resiko-resiko yang mungkin terjadi pada proyek. Simpulan dari penelitian ini adalah PT MSI sudah menerapkan manajemen proyek teknologi informasi dengan cukup baik melalui proses inisiasi, perencanaan, pelaksanaan dan pengendalian, evaluasi proyek dan penutupan proyek. Hal ini dilihat resiko yang ditemukan tidak banyak dan hanya dibutuhkan sedikit perbaikan dalam mengelola resiko pada proyek tersebut. Namun perusahaan belum melakukan pengukuran terhadap resiko manajemen proyek TI.

Abstract

Forecasting is performed due to the complexity and uncertainty faced by a decision maker. This article discusses the selection of an appropriate forecasting model with time series data available. An appropriate forecasting model is required to estimate systematically about what is most likely to occur in the future based on past data series, so that errors (the differences between what actually happens and the results of the estimation) can be minimized. A gauge is required to detect the required the value of forecast accuracy. In this paper ways of forecasting accuracy of detection are discussed using the mean square error (MSE) and the mean absolute percentage error (MAPE). The forecasting method uses Moving Average, Exponential Smoothing, and Winters method. With the three methods forecast value is determined and the smallest value of MSE and Mape is selected. The results of data analysis showed that the Exponential Smoothing is considered an appropriate method to forecast the sales volume of PT Satriamandiri Citramulia because it produces the smallest value of MSE and Mape.

Abstract

Facilities and advances in information technology such as digital library, online journal and references have not been well utilized by Regina Pacis High School. The school still implements the teacher centric teaching method where students are highly dependent on teacher that may inhibit the student’s development in independent learning. The author felt the need to propose an alternative solution to support student centric learning process by utilizing information technology advances. Therefore, an e-learning system design is made for Regina Pacis High School. To analyze the position of Regina Pacis High School the Porter's Five Forces is used. Meanwhile appropriate strategies for the school are determined using SWOT analysis. Results of Matrix IFE and Matrix EFE state that Regina Pacis High School is on the maintain-and-guard position while the results of the SWOT matrix states that the strategy of Strengths-Opportunities (SO) fits the conditions of the school. The strategies and implementation of e-learning system are expected to optimize the available technology to strengthen the position of Regina Pacis high school in the competitive market.
