Judul: Sinkronisasi antara Visualisasi Peta dan Query OLAP pada Spatial Data Warehouse Kebakaran Hutan di Indonesia
Abstrak: This research is a continuation from the previous research concerning data warehouse and spatial OLAP forest fire in Indonesia based on web using framework GeoMondrian and Geoserver. In the previous research, OLAP analysis process and hotspot location visualization are performed separately. In this research, the synchronization between OLAP analysis process and hotspot location visualization uses Spatialytics framework. This synchronization can be done because GeoMondrian and OpenLayers are embedded on Spatialytics, therefore OLAP analysis process and hotspot location visualization can be done by using just one query, that is MDX. This research develops a system which uses Spatialytics framework, PostGIS as spatial database, and GeoMondrian as spatial OLAP server. The system uses snowflake scheme with one table of fact and three dimensions consisting of the time dimension, the satelite dimension, and the location dimension. The System is built with threetier architecture consisting of the bottom layer, middle layer, and the top layer. The advantage of this system compared to the previous one is that this system takes only one input query, which is MDX to do OLAP analysis and show hotspot location. OLAP operations such as roll up, drill down, and slicing has been implemented in this system whilst dicing has not been implement because of Spatialytics limitation. For further research, system can be developed that is capable of dicing operation, data modification, such as insert, delete and update, without changing any scheme or structure.

Judul: Forest Fire Spatio-Temporal Data Warehouse using GeoMondrian and GeoServer
Abstrak: Indonesia is a country that has tremendous wealth of forests in the world. But Indonesia's forests decreases each year by deforestation amounted to 1.87 million hectares (FAO 2007). One of the main causes of deforestation in Indonesia is forest fires. Catastrophic forest fires cause major problems and need complex ways to overcome. One form of forest fire prevention is monitoring hotspots using the National Oceanic and Atmospheric Administration (NOAA) satellites. This satellite imagery capturing the form of hotspots, which could indicate the existence of forest fires based on location and time. Data obtained from these satellites have particularly large amount, causing the accumulation of data hotspot. This can be overcome by the presence spatio-temporal data warehouse technology with Spatial Online Analytical Processing (SOLAP) applications. Spatio-temporal data warehouse capabilities in integrating data into a quick and comprehensive information to assist decision-making process in terms of controlling forest fires. This study developed a geographic information system that integrates data warehousing applications spatio-temporaly with Spatial On-Line Analytical Processing (SOLAP) application using the framework Geomondrian and Geoserver as a web map server. Pre-process data such as data extraction, data transformation and loading of data, performed before the data warehouse is built in accordance with the dimensional data model (the concept of design in building a data warehouse) and integrated with Geoserver that handles the presentation of data in map form. The system was developed to visualize data of forest fires in the form of pivot tables, graphs and maps spread of hotspots in a web-based environment, so the system can support decision-making in an effort to control forest fire in Indonesia.

Judul: Quail Blood Cholesterol Levels (Coturnix coturnix Japonica) On Starters, Growers and Layers phase
Abstrak: Cholesterol is one of fat formation components which is also the main sterol in animal tissues. Therefore its presence are contributing to development and growth of the body. This study aimed to determine blood cholesterol levels and body weight of quail in the starter,grower and layer phases, which were taken at the age of 18 days, 25 days and 330 days. The quail (Coturnix coturnix Japonica) used were ten tails of the starter phase, grower phase and layer phase. Blood cholesterol levels were measured using a NESCO MultiCheck 3 in 1 tool and body weight was calculated using a digital scale. Cholesterol levels decreased from the starter (158,40 mg/dL) phase to the grower phase (123,00 mg/dL) and increased again in the layer phase (219,6 mg/dL). The highest blood cholesterol value was obtained in the layer phase. The body weight over time continued to experience an increase and the increase in body weight from the starter to the layer phase was not followed by an increase in cholesterol levels. Cholesterol levels are used according to their physiological needs, Kolesterol merupakan salah satu komponen pembentuk lemak yang juga merupakan sterol utama dalam jaringan hewan, oleh karena itu kehadirannya memberikan kontribusi untuk perkembangan dan pertumbuhan tubuh. Penelitian ini bertujuan untuk mengetahui kadar kolesterol darah dan bobot badan burung puyuh pada fase starter, grower dan layer, yang diambil pada umur 18 hari, 25 hari dan 330 hari. Burung puyuh (Coturnix coturnix Japonica) yang digunakan sebanyak sepuluh ekor pada masing-masing fase starter, fase grower dan fase layer. Kadar kolesterol darah diukur menggunakan alat NESCO MultiCheck 3 in 1 dan berat badan dihitung menggunakan timbangan digital. Kadar kolesterol menurun dari fase starter (158,40 mg/dL) ke fase grower(123,00 mg/dL) dan meningkat lagi pada fase layer(219,6 mg/dL). Nilai kolesterol darah tertinggi diperoleh pada fase layer. Bobot badan dari waktu ke waktu terus mengalami peningkatan yang dan peningkatan bobot badan dari fase starter ke fase layer tidak diikuti dengan peningkatan kadar kolesterol yang artinya bobot badan tidak berpengaruh pada kadar kolesterol burung puyuh. Kadar kolesterol digunakan sesuai dengan kebutuhan fisiologisnya
