The purpose of our study was to explore relationships among children's aural perception, music listening condition, and the accuracy of children's reading of listening maps. The aural discrimination skills of 41 elementary children were tested using the Intermediate Measures of Musical Audiation (IMMA). The children were then systematically assigned to one of three listening conditions: passive, unstructured active, or structured active. After listening to European art music according to their assigned condition, every child traced a graphic listening map while listening to the music a second time. Results of an ANCOVA with accuracy of map reading as the dependent variable, listening condition as factor, and IMMA as covariate, showed a significant effect for the IMMA [F (1, 37) = 8.86, p < .01], but no significant effect for listening condition. In a separate analysis, IMMA scores were shown to be related to piano experience. When group means for accuracy of map reading were compared by piano experience, children with piano experience had a significantly higher mean accuracy score of 48.25, SD = 18.75 (n = 16) compared to children with no piano experience, M = 32.44, SD = 17.39 (n = 25), t = 2.76, p < .01. Our results support previous research in which investigators found that music experience explained accuracy of music-reading ability in children and adults.

ABSTRAK Bakau (Rhizopora mucronata) merupakan salah satu jenis mangrove yang terdapat pada kawasan rehabilitasi hutan mangrove Desa Mojo, Kabupaten Pemalang.Jenis mangrove ini ditanam karena bibitnya mudah diperoleh dan disemai sehingga mendominasi pada kawasan tersebut.Untuk mengetahui faktor-faktor yang berkaitan dengan pertumbuhan mangrove, maka telah dilakukanpenelitian tentang hubungan antara kualitas tanahdengan luasan helai daun mangrove.Jumlah sampel yang digunakan adalah405helai daun yang dipilih dengan kondisi yang sama dan berasal dari 9 stasiun penelitian. Dalam stasion yangsama dilakukan pula pengambilan sampel tanah sampai kedalaman 50 cm, untuk dianalisis kandungan bahan organik dan sifat fisik-kimia.  Sampel daun yang diperoleh kemudian diproses dalam photo studio mini buatan untuk diambil gambarnya menggunakan kamera digital beresolusi tinggi dalam jarak 30 cm dan dihitung luasannya denganperangkat lunak komputer Corel Draw X7.Analisis data menggunakan PCA dan hasilnya menunjukkan, bahwa dari semua variabel yang diukur dari tanah, maka hanya faktorbahan organik saja yang memiliki korelasi positif tinggi dengan luasan daunR. mucronata. Kata kunci: Pohon Bakau, Luasan Daun, Hutan Mangrove Desa Mojo ABSTRACT Mangrove (Rhizopora mucronata) is one of the mangrove species found in the rehabilitation area of mangrove forest of Mojo Village, Pemalang Regency. This type of mangrove is grown because the seeds are easy to obtain and sowing so as to dominate in the area. To know the factors related to the growth of mangroves, so has been conducted research on the relationship between soil quality with the extent of mangrove leaves. The number of samples used is 405 leaf blades selected under the same conditions and derived from 9 research stations. In the same station, soil sampling is done up to 50 cm depth, to analyze organic material content and physical-chemical properties. The leaf samples were then processed in an artificial mini studio photo to be photographed using a high resolution digital camera within 30 cm and calculated the extent of Corel Draw X7 computer software. Analysis of data using PCA and the results show, that of all variables measured from the soil, then only the factor of organic material alone has a high positive correlation with the leaf area of R. mucronata. Keywords: Mangrove, Leaf Extents, Mojo Village’s Mangrove Forest
