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: Peningkatan Kinerja Sistem Spatial Data Warehouse Kebakaran Hutan Menggunakan GeoServer dan GeoMondrian
Abstrak: Forest fire can be periodically detected by satellite as hotspot areas that occur at specified time and location. The frequency of forest fire in Indonesia is high so the data collection of hotspots will be very large. That data collection of hotspots can be stored into specific storage such as data warehouse. A data warehouse system of forest fire was built in the previous research using GeoServer as web map server and GeoMondrian as OLAP Server. However, that system still has some limitations such as the poor system runtime and the low amount of retrieved hotspots. In this research, the system would be reconfigurated in order to fix those limitations so that the system performance would increase. The configuration involves some part of the system including Java Runtime Environment, database source, data cube schema, and error handling in OpenLayers. It has resulted 155 ms higher speed of runtime and 1310 higher number of retrieved hotspots.

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
