The study involved 125 students by filling out an online questionnaire. Parameter estimation of the model was performed using the Structural Equation Model (SEM). The overall student satisfaction level with BK services was 94%. The competence of BK teachers and the consultation work program have a dominant role in influencing satisfaction. BK information services have a positive influence on satisfaction, while personality factors, discussion room facilities, and classical work programs have a negative influence on student satisfaction.

Judul: Evaluasi Diri Sekolah Tingkat Pendidikan Sekolah Dasar Menggunakan Model Persamaan Struktural Multisample (Studi Kasus Provinsi Bali dan Daerah Istimewa Yogyakarta)
Abstrak: Education has an important role in preparing human source for national development. The province of Bali and Special Region of Yogyakarta got either first or second highest score of the Elementary School National Exam in 2010 and 2011. National Exam can be used as an indicator to see the quality of education, so these provinces can be used as a reference to improve the education quality of other provinces. The success of the National Exam had related with the the successful achievement of the Standar Nasional Pendidikan (SNP). SNP had been used as instrument in Evaluasi Diri Sekolah which is a government program to monitoring the quality of school education. SNP consists of eight standards that are interconnected with each other. In this study use six SNP outside of Standar Pembiayaan and Standar Sarana dan Prasarana, SNP variables can not be measured directly. This study examines the effect of differences in the relationship between structural equation modeling (SEM) of Bali and Yogyakarta Province, so the analysis is multisample SEM. SEM showed that Standar Pengelolaan affect Standar Pendidik dan Tenaga Kependidikan (PTK). Standar PTK affect the Standar Isi, Standar Proses, and Standar Penilaian. Standar Isi affect Standar Proses and Standar Proses affects Standar Kompetensi Lulusan (SKL).

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
