Judul: Hierarchical Clustering Pada Data Time Series Hotspot Provinsi Riau
Abstrak: Land and forest fires become yearly issues in Indonesia, particularly in Riau province. This work applied the hierarchical clustering method for hotspot time series data using average distance formula to analyze hotspots distribution in Riau province. This work focuses on the hotspots distribution in June, July and August for the period 2001-2012. Time series data decomposition was generated to obtain the hotspot occurrence patterns over the period. Hierarchical clustering on the data results 4 clusters at the height of dendrogram about 300. Most of hotspots in these clusters are located in plantation.

Judul: Outlier detection on hotspot data in province riau using K-Means Clustering algorithm
Abstrak: Kebakaran hutan merupakan masalah yang selalu berulang di Provinsi Riau. Salah satu solusi dari masalah ini adalah memanfaatkan data titik api hasil penginderaan jarak jauh. Tujuan penelitian ini adalah mendeteksi pencilan yang terdapat pada data titik api di Provinsi Riau dari tahun 2001 hingga 2012. Deteksi pencilan dilakukan dengan menggunakan metode clustering k-means serta digunakan pendekatan pencilan global dan kolektif. Pada fungsi kmeans digunakan nilai k sebesar 10 sehingga dihasilkan nilai sum of squared error sebesar 18 526.14. Hasil menunjukkan bahwa berdasarkan pendekatan pencilan kolektif dideteksi pencilan titik api terdapat pada cluster 5, 7, dan 10. Di samping itu diperoleh 30 pencilan titik api berdasarkan pendekatan pencilan global. Kemunculan pencilan pada data titik api banyak terjadi pada bulan Februari, Maret, Juni, dan Agustus. Frekuensi pencilan titik api tertinggi terjadi pada tahun 2005 yaitu sebanyak 1118 titik api pada 21 Juni 2005. Adapun frekuensi pencilan titik api terkecil yaitu sebanyak 295 titik api pada tahun 2005 dan rata-rata frekuensi pencilan titik api sebesar 482.22., Forest fire is considered as periodic event in several areas in Indonesia including in Riau Province. One of solutions in fire prevention is analyzing hostpot occurrences data that are produced by remote sensing technology The objective of this research is to detect outliers on hotspot data in Riau Province for the period 2001 to 2012. Outlier detection was done using the clustering k-means algorithm, and use a approach global outliers and collective outlier. The best clustering result was selected on the number of cluster 10 and the sum of squared error value is 18526.14. The results showed that based on a collective outlier approach, the outliers were obtained on cluster 5, 7 and 10. In addition, 30 outliers on hotspot data were detected based on the global outlier approach. The outliers on the hotspot data were mostly occurred in February, March, June, and August. The highest frequency of outliers occurred in 2005 reach 1118 hotspots on 21 June 2005. While the lowest frequency of outliers is 295 in 2005 and the average frequency of outliers is 482.22.

Judul: Case Study of Gallbladder Mucocele and Treatment Used In Small Animals
Abstrak: Gallbladder mucocele (GM) is defined as distention of the gallbladder caused by an inappropriate accumulation or deposition of high concentrations of bile. The purpose of this case study is to study GM conditions in small animals and to report the clinical sign and characteristics of GM through the sonogram interpretation and blood chemistry test evaluation, and studies related to the therapy given and other treatments recommended. A 14-year-old Toy Poodle dog has been diagnosed with severe GM and cholecystitis. No pain signs were shown during the physical examination as asymptomatic is a common characteristic in the early stage of biliary related diseases. In this study Abdominal ultrasonography interpretation and blood chemistry evaluation was conducted in 2021-2022 and analyzed as a secondary data source. Ultrasonography results showed presence of hyperechoic, immobile deposits in gallbladder accompanied by wall thickening and enlarged in size, followed by a significant increase in the enzyme alkaline phosphatase (ALP). This study has summarized mainly the diagnosis and treatments of GM in small animals and suitable alternatives treatments were recommended to encounter the GM conditions in small animals. The effectiveness of combined therapy shows the positive impact on the patient, the condition of GM has been under control.
