Abstract

This research is about to examine the site-suitability of horticultural plantation at the west part of Lawu. The research was conducted through a survey upon the cultivated horticultural commodities by comparing their agronomic prerequisite with measured climatic conditions and land performances. The research shows that the most critical determinant for the performed horticultural cultivation is the slope of the landscape. Hence, horticultural cultivation activities must emphasize for not to ignore the importance of standing crop and slopeland’s management.   Keywords: Land suitability evaluation.

Abstract

ABSTRACTThe research aims to utilizing interaction earthworm with environment in the calcareous land. The research can be specified through a two-stage: the first year and second year. Results from our earlier studies aims: (1) to find out earthworm interaction with calcareous land, (2) identification of earthworm in calcareous land. Using three examples from different land: monoculture, polyculture, and agroforestry. The research data collected with 3 repetitions in every land. Measurement of micro climates include temperature, humidity, pH, and light intensity. Identification the type of earthworm consist of: the body shape, color, position and the form of klitelum, the prostomium, setae, and the position of genetal males and females. Identification using binocular microscopy at 10 to 40x magnification. Analysis correlation  were tested to figure out the relationships between variables. If the correlation of relationship between variable is very real or real continued test by STEPWISE REGRESSION to find out the most influential environmental factors on earthworms living. The result of the research are: (1) Earthworm had very significant most correlation (significant = 0,01) with air humidity (r= 0,855), light intensity (r = - 0,825), and soil humidity (r = 0,60). Other environmental factors had a significantly small influence  (pH, r =0,17; soil temperature, r = - 0,28; and temperature r = 0,03). Air humidity is the most influential environmental factors on earthworms living (2) identification of the types earthworm in different three land was found 2 species: Pontoscolex corethrurus and Metaphire javanica. In monoculture land is dominated by Metaphire javanica, whereas in Polikultur and Agroforestry land is dominated by Pontoscolex corethrurus. As a result, air humidity is the most influential environmental factors on the lives of earthworms and other environmental factors is relative small influence. On the calcareous land found two species of earthworm: Pontoscolex corethrurus and Metaphire javanica.     Keyword:Calcareous land environment, Identification earthworm, Pontoscolex corethrurus, Metaphire javanica

Abstract

Penelitian ini bertujuan untuk mengidentifikasi kemampuan berpikir ilmiah siswa kelas XI melalui studi kasus siswa kelas XI IPA 1 di SMA Negeri 1 Sanden. Penelitian merupakan penelitian deskriptif kualitatif. Subyek penelitian adalah siswa kelas XI IPA 1 di SMA Negeri 1 Sanden yang berjumlah 28 orang. Teknik perolehan sample adalah dengan metode purposive sampling. Teknik pengumpulan data dengan menggunakan tes berpikir ilmiah, observasi dan wawancara. Instrumen tes kemampuan berpikiri lmiah berjumlah 25 soal dan memuat indikator berpikir ilmiah meliputi: inquiry, analisis, inferensi, argumentasi. Instrumen untuk observasi berupa lembar observasi pembelajaran, dan instrumen wawancara menggunakan pedoman wawancara. Tes kemampuan berpikir ilmiah yang digunakan dalam penelitian ini telah divalidasi. Data yang diperoleh diuji dengan menggunakan statistika deskriptif. Hasil penelitian menunjukkan kemampuan berpikir ilmiah siswa masih rendah. Rata-rata skor yang diperoleh siswa dalam mengerjakan keseluruhan soal kemamapuan berpikir ilmiah adalah 65,1. Skor yang dicapai siswa tersebut dibawah KKM yang ditetapkan sekolah. Hal ini mengindikasikan kemampuan berpikir ilmiah siswa secara umum cukup rendah. Hasil pengukuran pada tiap aspek berpikir ilmiah menunjukan rata-rata skor yang diperoleh siswa kurang maksimal, aspek berpikir ilmiah meliputi: Aspek inkuiri menunjukkan capaian rata-rata skor siswa 25,83; Aspek Analisis menunjukkan rata-rata skor siswa 31,33; aspek inferensi menunjukkan rata-rata skor siswa 47; dan aspek argumentasi memiliki rerata skor yang tertinnggi yaitu 66. Kurang maksimalnya perolehan skor tes berpikir ilmiah secara umum disebabkan siswa belum terbiasa dilatihkan kemampuan berpikir ilmiah dalam pembelajaran. Pelatihan berpikir ilmiah dalam pembelajaran, dapat dilakukan dengan penggunann model pembelajaran yang melatih siswa untuk dapat menemukan pengetahuan seperti peneliti melakukan proses penelitian yaitu dengan model pembelajaran berbasis inkuiri. Berdasarkan hasil yang diperoleh tersebut, peneliti merekomendasikan adanya penelitian lanjutan berupa tindak lanjut untuk menyelesaikan masalah berpikir ilmiah siswa.
