摘要

本研究旨在描述该项目在生态系统材料中的科学过程技能的质量。通过描述性的方法进行在线实地研究。其中包括有效性测试、可靠性测试、能级测试和公差能力测试。这项研究是在苏卡步市4国高中进行的。这项研究的总人口是大二基帕学生。本研究采用样本进行采样。这项研究的样本是35名大二IPA 3学生。分析结果表明,某一条款的有效性水平,有效百分比为63%,无效比例为37%。使用AnatesV4程序和数字N = 35的显著5%的可靠性得到了r表= 0.334,而r计算= 0.76。因为r的计数是。76 > r表是。334,所以使用的仪器是可靠的。然后从困难的程度来看,最困难的70.3%(29)百分比属于中等。从不同的角度来看,获得51.2%的比例是好的还是非常好的相对比例是非常大的。总之,有效的、可靠的问题可以用于进一步的研究。禁止这项研究以描述生态系统材料中科学过程技能的质量。这一研究类型通过描述性的阴影进行在线研究。一些测试包括有效性、可靠性、困难和差异。这项研究是由东苏加梅市高中预涉的。这项研究的人口是大二科学的学生。本研究的样本是前期样本。这项研究的样本是35年级科学3班的学生。分析表明,从问题的有效性来看,问题的发生率是63%,而潜在问题的比率是37%。可靠性测试结果采用了具有N号号码的5%的重要级别,以及使用0334时rtable = 0334, while rcount = 0.76。因为计数为0.76> r table .334,使用的仪器是可靠的。在不同程度上,在70。3%(29)最困难的类别是在介质类别中。在被赋予超能力的条件下,我们固定了51。2%的两者是好的还是非常好的关系到一个非常大的percentage。在结结语中,一个有效而可靠的问题可能已经用于进一步的研究。

Analisis Butir Soal Keterampilan Proses Sains Pada Instrumen Uji Coba Materi Ekosistem
Abstrak Penelitian ini bertujuan untuk mendeskripsikan kualitas butir soal keterampilan proses sains pada materi ekosistem. Jenis penelitian yang digunakan yaitu penelitian lapangan secara online melalui pendekatan deskriptif. Beberapa uji yang dilakukan di antaranya uji validitas, uji reliabilitas, uji tingkat kesukaran, dan daya pembeda. Penelitian ini dilaksanakan di SMA Negeri 4 Kota Sukabumi. Populasi dari penelitian ini yaitu siswa kelas XI IPA. Pengambilan sampel dalam penelitian ini dilakukan secara purposive sampling . Sampel dalam penelitian ini yaitu siswa kelas XI IPA 3 yang berjumlah 35 orang. Hasil analisis menunjukkan bahwa kualitas butir soal dari tingkat validitas soal, persentase soal valid sebesar 63% dan yang tidak valid sebesar 37%. Hasil uji reliabilitas soal dengan menggunakan program AnatesV4 dan taraf signifikan 5%  dengan jumlah N = 35 diperoleh nilai r tabel = 0,334, sedangkan r hitung = 0,76. Karena r hitung 0,76 > r tabel 0,334, maka Instrumen yang digunakan bersifat reliabel. Kemudian dari segi tingkat kesukaran, bahwa pada persentase 70,3% (29) yang kategori tingkat kesukaran paling banyak berada kategori sedang. Dan dari segi daya pembeda, memperoleh persentase 51,2% yang kategori baik atau sangat baik relatif persentase yang sangat besar. Kesimpulannya, soal yang sudah valid dan reliabel sudah dapat digunakan untuk penelitian selanjutnya.
