Judul: Rancang Bangun Sistem Informasi Konservasi Tumbuhan Obat Hutan Tropika Berbasis Web
Abstrak: Medicinal plants are tremendous natural richness in Indonesia with at least 2039 species from Indonesian forest. On the other hand, the use of medicinal plants experiencing great challenges such as degradation of either in medicinal plant species or in indigenous knowledge aspects in the use of medicinal plants. The purpose of this study was to produce a web-based information system applications, analyzing the level of people's interest in medicinal plants, and the response of the information system. System development includes planning, analysis, design, implementation and testing including a survey on the public, and system maintenance. Information system that contains data of medicinal plants was successfully built and implemented on the community. Based on the current survey implementation, information system gives effect to the increase in the level of public interest in medicinal plants.

Judul: Development of information systems design landscape medicinal plants in cloud computing
Abstrak: Sistem bertujuan memberikan akses informasi mengenai desain lanskap tanaman obat keluarga yang dapat digunakan sebagai inspirasi tidak hanya bagi masyarakat berlatar belakang arsitektur lanskap tetapi juga bagi masyarakat pada umumnya. Pada penelitian ini, dikembangkan Sistem Informasi Taman Tanaman Obat Keluarga (SITOGA) menggunakan teknologi cloud computing dengan layanan Platform as a Service (PaaS). Hasil pengembangan sistem adalah desain taman sesuai dengan penyakit tertentu, perkiraan anggaran taman, dan resep yang dapat diracik dari komponen pada taman tersebut. Pengguna dapat memilih penyakit diabetes kemudian sistem menampilkan gambar desain taman diabetes. Pada gambar desain, pengguna dapat melihat informasi tanaman obat dengan mengklik objek tanaman yang ada. Sistem juga menampilkan harga tanaman, volume tanaman yang dibutuhkan, dan total perkiraan biaya pembangunan taman. Sistem juga menampilkan daftar resep (contoh: ramuan tapak dara sebagai obat bagi penderita diabetes) dan cara pengolahannya. Jika pengguna merasa ukuran taman terlalu luas, pengguna diberikan pilihan untuk mengurangi luas taman dengan cara mengurangi rasio ukuran taman. Rasio yang disediakan yaitu 25%, 50%, dan 75% dari ukuran awal., The system aims to give access of information on the design of medicinal plants garden for specific and general users. This research develops a system called SITOGA that utilizing cloud computing technology of Platform as a Service (PaaS) type. SITOGA portrays garden design, budget estimation, and medicinal recipes which can be made from the medicinal plants of the garden. User can choose diabetes disease. Next, the system will provide diabetic garden design. On the design figure, user can explore the informations of the medicinal plants presented by clicking the objects. The system also presents plants price, plant volume, and total budget estimation to build the garden. In addition, the system presents recipe list (example: ramuan tapak dara as a medicine for diabetics) and the technique to implement the recipe. If the users think that the size of garden is too wide, they can cut it off by select the ratio of their garden size. The offered ratio are 25%, 50%, and 75% of its original size.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
