Technology is one important factor that supports accuracy result of a disease in health. Along with technology, one’s knowledge could be broadening so he can make one exact decision about specific disease to get maximal result. Based on above considerations, it is designed a supporting decision-making system based on entered data, processed using weighting in AHP to know the result. The programming language is using PHP and the database using MySQL. The designing result could help doctors to choose specific medicine for the patients and help them to find information about cardiac failure and what stages to be done to help the patients healing.

Makalah ini menjelaskan hubungan alur kerja baru antara program pemodelan CAD 3D (Rhino/Grasshopper) dan simulasi pencahayaan dengan (Radiance/Daysim). Alur kerja perancangan yang sangat efektif dalam Rhino disajikan secara langsung dengan mengekspor geometri, material properties, dan sensor grid ke dalam format Radiance/Daysim untuk menghitung serangkaian indikator performa termasuk peta radiasi matahari serta faktor pendistribusian pencahayaan dalam setahun. Hasil simulasi secara otomatis dikirim kembali ke dalam Rhino menggunakan pemetaan warna. Dengan menggunakan Grasshopper, parameter desain utama seperti ukuran jendela dan deskripsi material dapat diubah secara bertahap dan hasil simulasi dapat dikombinasikan menjadi sebuah simulasi performa bangunan dalam bentuk animasi transformasi parametrik. Desain alur kerja ini telah secara khusus dikembangkan bagi proses perancangan arsitektur dengan menyediakan semua feedback yang sangat berguna bagi perancang secara interaktif dari tahap rancangan skematis sampai tahap pengembangan perancangan.

The use of diverse database technology in enterprise today can not be avoided. Thus, technology is needed to generate information in real time. The purpose of this research is to discuss a database replication technology that can be applied in heterogeneous database environments. In this study we use Windows-basedMS SQL Server database to Linux-based Oracle database as the goal. The research method used is prototyping where development can be done quickly and testing of working models of the interaction process is done through repeated. From this research it is obtained that the database replication technolgy using Oracle Golden Gate can be applied in heterogeneous environments in real time as well.

Human life is more complex with more and diverse human activities, requires an adjustment function on an area of the city. City areas will be abandoned later died at a city area with many buildings that are not maintained anymore. Therefore it needs adjustment function, a function of the new requirement is necessary to maintain the vitality of an area. This principle applies generally to the entire region, including the old town conservation area. Many examples of successful for the revitalization of old town that is how the old town area can adapt to the needs of the new society. Cisangkuy area is part of the initial planning of Bandung city, which is planned as a residential area for officials Dutch East Indies. Current conditions, the region has experienced a change to suit the needs of society. On the other hand, this region also have the value - historical value can still be inherited by future generations. Therefore, the necessary arrangements for the changes that occur to meet the needs of today's society does not damage the characteristics of the region as a whole.

The article explores the influence of database compression on processing time in generating online test results through experimental study. The study uses three level compressions consists of none, row and page in table used by online test system. The experiment shows that using page compression results in faster processing time and less space compared to none and row compression, and the optimal row for compression is between 1001 and 2000 rows. In summary, to reduce space usage and processing time, it is better to use page compression in user answer table of online test system and to group the participant in schedule so that users’ answer will be between 1001 and 2000 rows.
