Judul: Klasifikasi Data Spasial untuk Kemunculan Hotspot di Provinsi Riau Menggunakan Algoritme ID3
Abstrak: Forest fire is one of the environmental issues that occurs almost every year in Indonesia including in Riau Province, which causes negative impacts for human life. The large data of hotspot distribution can be analyzed using one of spatial data mining techniques, namely spatial decision tree. The purpose of this research is to classify the hotspot occurences in Riau province in order to obtain the classification rules. In this research, the spatial decision tree is developed using ID3 algorithm. The result shows that the highest accuracy is 70.80%. The classification model consists 125 classification rules that can be used to predict the hotspot occurrences.

Judul: Klasifikasi Titik Api di Bengkalis Riau Menggunakan Algoritme ID3 Spasial yang Diperluas
Abstrak: Forest fire in Riau Province including Bengkalis district, are frequently occurred every year. Hotspot is an indicator for forest fire events. Hotspots monitoring by the NOAA satellite is one of the efforts to prevent forest fires. Hotspot data are spatial data. In order to analyze the data, spatial algorithms are required. The extended spatial ID3 algorithm is a spatial classification algorithm for creating a spatial decision tree from spatial datasets. This research applied the extended spatial ID3 algorithm to the forest fires data in Bengkalis district, Riau. The data include hotspots and non-hotspots, weather data, socio-economic data, and geographical characteristics of the study area. The result of this research is a decision tree with income source layer as the root node. As many as 137 rules were generated to the tree. The accuracy of the tree is 75.66% and 41.38% respectively on the forest fires dataset in Bengkalis district and Rokan Hilir district Riau.

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
