Abstract Fluid dynamics has some complex and unobservable concept, however, tests are rarely developed to measure students’ understanding of these concepts. This condtion make a difficulty to map students’ mental models with existing instruments. Based on that problem, this study aims to develop FD-MT (fluid dynamic-multi tier test) as a diagnostic test for measure students’ mental model on fluid dynamic concept. The ADDIE (Analyzing, Designing, Developing, Implementing, Evaluating) is a research method that used in this study. The data were collected by FD-MT will be analyzed by rasch model analysis, include the reliability, the validity, item fit and the differential item function. Student mental model clasified as Scientific, Synthesis-A (Sy-A), Synthesis-B(Sy-B), Syinthesis-C (Sy-C), Synthesis-D(Sy-D), and Initial. The participant of this study are 20 students in the eleventh grade (9 boys and 11 girls, 16-17 age in average) at high school in Bandung. Based on result study shows that students’ mental model mostly in mental Sc (8.18%), Sy-A (3.18%), Sy-B (21.36%), Sy-C (19.09%), Sy-D (38.18%) and In (10%), and incompleted answer (Nr = 0%). This conclude that, FD-MT is able to measureing students’ mental model on fluid dynamic concept.

AbstractLasara is a mytological object being that is often symbolized in Nias material culture such as osa-osa, sarcofagus, wooden coffin, grave, lasara on village gate, traditional house ornaments, and sword handle. This comparative study-enhanced descriptive-analytical research method is aimed at finding connection between lasara, which is a part of Nias people mythology, and its interpretation through the outlying elements to obtain a complete understanding of lasara. The analysis reveals that in a society where mythology is an innate value, lasara is understood as a symbol of a ride related with religious and social aspects. Lasara is symbolized as a boat used in the migration of Nias people through the sea, as well as a spiritual ride in its religious life.AbstrakLasara merupakan makhluk mistis yang banyak diwujudkan dalam budaya materi di Nias seperti osa-osa, sarkofagus, peti jenazah kayu, bangunan kubur, lasara pada gerbang desa, ornamen rumah adat, dan hulu pedang. Untuk menjawab permasalahan mengenai pemaknaan lasara dalam pemahaman masyarakat Nias digunakan metode deskriptif analitik yang diperkuat oleh studi komparatif yang bertujuan untuk menarik benang merah antara objek yang dikenal sebagai lasara yang menjadi bagian dari mitologi masyarakat Nias dengan pemaknaannya melalui aspek-aspek yang melatarbelakanginya sehingga dapat diperoleh pemahaman yang utuh terhadap salah satu bentuk kebudayaan di daerah Nias tersebut. Dari analisis tersebut dapat terjawab bahwa dalam pemahaman masyarakatnya yang masih sangat terikat oleh mitologi, lasara dimaknai sebagai simbol yang berkaitan dengan struktur sosial serta simbol wahana terkait dengan aspek religi dan sosial. Lasara sebagai wahana dikaitkan dengan bentuk perahu yang berhubungan dengan proses migrasi orang Nias melalui jalur lautan, serta sebagai kendaraan arwah dalam kehidupan religinya.
