Penerapan Bimbingan Kelompok dengan Teknik Permainan Kerja Sama untuk Menigkatkan Kemampuan Interaksi Sosial Siswa Kelas X-1 SMA Negeri 3 Lamongan

Latar belakang dari penelitian ini dimulai dari hasil wawancara kepada guru BK yang menyatakan bahwa sebanyak 20%  kelas X-1 mempunyai kemampuan interaksi sosial rendah. Beberapa faktor yang menyertai terjadinya kemampuan interaksi sosial rendah adalah siswa yang hanya berteman dengan teman tertentu saja, pada saat berpapasan dengan teman tidak menyapa, ketika diskusi kelompok hanya diam saja, dan sulit diajak bekerja sama ketika belajar kelompok. Penelitian ini bertujuan untuk menguji penerapan bimbingan kelompok dengan teknik permainan kerja sama untuk meningkatkan kemampuan interaksi sosial siswa kelas X-1 SMA Negeri 3 Lamongan. Penelitian ini merupakan penelitian kuantitatif dengan menggunakan rancangan penelitian pre-test and post-test one group design. Subjek dalam penelitian ini adalah 6 siswa kelas X-1 SMA Negeri 3 Lamongan yang teridentifikasi memiliki skor kemampuan interaksi sosial rendah, yang dapat diketahui melalui angket pada pengukuran awal (pre-test). Metode pengumpulan data yang digunakan dalam penelitian ini adalah angket kemampuan interaksi sosial siswa yang dikumpulkan dengan angket dan teknik analisis data yaitu statistik non parametrik dengan Uji Tanda (Sign Test). Setelah diadakan analisis dengan menggunakan uji tanda, dapat diketahui rtabel = 0,016 lebih kecil dari α sebesar 5% = 0,05. Jadi dapat disimpulkan bahwa ada perbedaan kemampuan interaksi sosial sebelum dan sesudah penerapan bimbingan kelompok teknik permainan kerja sama. Berdasarkan hasil perhitungan diatas mean pre-test sebesar 149,83, mean post-test sebesar 197,66 dan selisish antara mean pre-test dan post-test sebesar 47,83. Dengan demikian  ditolak dan  diterima. Hal ini berarti hipotesis penelitian yang berbunyi “ Bimbingan kelompok dengan teknik permainan kerja sama dapat meningkatkan kemampuan interaksi sosial siswa kelas X-1 SMA Negeri 3 Lamongan” diterima. Kata Kunci : Bimbingan kelompok, Teknik permainan kerja sama, Interaksi sosial. &nbsp

Struktur Komunitas Fitoplankton di Perairan yang Terdampak Air Bahang PLTU Paiton Kabupaten Probolinggo Jawa Timur

PLTU Paiton merupakan salah satu pembangkit listrik tenaga uap menggunakan air sebagai pendingin kondensor kemudian dikembalikan lagi ke perairan sekitar sebagai air bahang, sehingga akan memberikan input panas bagi perairan. Meningkatnya suhu perairan akibat air bahang ini, secara langsung maupun tidak langsung akan berpengaruh terhadap komponen biotik dan abiotik penyusun ekosistem laut, salah satu yang akan terpengaruh adalah fitoplankton yakni berupa struktur komunitas yang meliputi keanekaragaman, kelimpahan jenis, maupun keseragaman jenis fitoplankton disuatu perairan. Dari deskripsi tersebut, maka dilakukan penelitian mengenai struktur komunitas fitoplankton di perairan yang terdampak air bahang PLTU Paiton yang dilakukan pada bulan Maret hingga Juni 2015 dengan 6 kali pengambilan sampel di lima titik sekitar PLTU Paiton (Mercusuar, Intake, Outlet, Banyuglugur, dan Tengah). Data struktur komunitas yang diambil berupa kelimpahan, keanekaragaman, dan keseragaman fitoplankton yang selanjutnya dianalisis secara deskriptif kuantitatif dan diuji menggunakan analisis regresi linier serta analisis ordinasi. Hasil dari penelitian ini adalah menunjukkan bahwa berdasarkan uji regresi linier dan ordinasi RDA, struktur komunitas fitoplankton di perairan sekitar PLTU Paiton tidak dipengaruhi air bahang secara signifikan. Secara deskriptif kuantitatif struktur komunitas fitoplankton ini digambarkan dengan hasil keanekaragaman yang tergolong sedang (2.3026<H<6.9078) dengan nilai kelimpahan berkisar antara 7819 ind/m3 hingga 16255 ind/m3. Serta nilai keseragaman jenis labil (0.5< E ¤0.75) ditandai dengan adanya dominansi genus Oscillatoria sp. di setiap titik

Faktor- Faktor yang Berhubungan dengan Perilaku Pola Tidur Santriwan dan Santriwati Kelas XI Ma Pondok Pesantren Modern Islam Assalaam Surakarta

World Association of Sleep Medicine (WASM) stated 45 % of the world population had sleep disturbances with some conditions, like insomnia, sleepless duration, and etc. Journal of school Health reported that 90% of teenagers in Indonesia had sleep less than 8-10 hours a day according to recommendation.10% of teenagers reported sleeping less than 6 hours a day. In Solo, there were 20 boarding schools that the majority of its students had a sleep duration less than 8 hours a day. The purpose of this study was to analyze the factors related to the pattern of student sleep behavior in class of XI MA Assalaam Surakarta. This research used a cross-sectional study design, with a population of 148 respondents with total sampling technique for quantitative and 3 informants triangulation with purposive sampling for qualitative. The instrument used was a questionnaire and an interview guide. Analysis of the data used chi-square test for the bivariate analysis with significance level of 90%. At 64.9% of respondents had a good sleep pattern behavior, while 35.1% of respondents still have behavior patterns of poor sleep. Bivariate analysis showed that there was a correlation between physical activity (p= 0.000), and regulatory boarding schools (p=0,005) and there was no correlation between knowledge, attitude, the availability of sleep time, the facilities from school, support from peers, support from ustadz/ustadzah, gender with the behavior ofthe sleep patterns of students grade XI MA Assalaam. The boarding school should be reduced physical activity, especially non-academic activities in class XI students

Identifikasi Penalaran Aljabar Mahasiswa Dalam Menyelesaikan Masalah Relasi Rekursif Menggunakan Alat Peraga Menara Hanoi Ditinjau Dari Gaya Belajar

This study aims to identify the level of students' algebraic reasoning in solving recursive relation problems using tower hanoi props in terms of learning styles. This research is a descriptive exploratory research with a qualitative approach. The instruments in this study consisted of learning style questionnaires, Mathematics Ability Tests, Problem Solving Tasks, and task-based interviews. The research begins with giving tests of mathematical ability and learning style agket to 8 semester VI students of the STKIP PGRI Sumenep mathematics education study program in Sumenep to obtain three subjects, each with visual, auditory and kinesthetic learning styles with equal mathematical abilities and of the same gender. After that, it was followed by giving problem solving tasks and task-based interviews twice. Time triangulation is used to check the validity of the data. The data analysis technique consists of 5 stages, namely data categorization, data reduction, data presentation, data interpretation, and drawing conclusions. The results show that the visual subject is higher than level 2 but has not reached level 3, the auditory subject is at level 2, and the kinesthetic subject is at level 3. The three subjects have reached the stage of solving the problem, but the one who can solve the problem until they find the final solution is only the kinesthetic subject. The implication of research in learning is that teachers can more easily design learning according to their learning styles so that they can hone students' algebraic reasoning

Proximal Giant Neurofilamentous Axonopathy in Mice Genetically Engineered to Resist Calpain and Caspase Cleavage of α-II Spectrin

We use 1,2-diacetylbenzene (1,2-DAB) to probe molecular mechanisms of proximal giant neurofilamentous axonopathy (PGNA), a pathological hallmark of amyotrophic lateral sclerosis. The spinal cord proteome of rodents displaying 1,2-DAB-PGNA suggests a reduction in the abundance of αII-spectrin (Spna2), a key protein in the maintenance of axonal integrity. Protein immunoblotting indicates that this reduction is due Spna2 degradation. We investigated the importance of such degradation in 1,2-DAB-PGNA. Spna2 mutant mice lacking a calpain- and/or caspase-sensitive domain (CSD), thus hypothetically resistant to 1,2-DAB, and wild-type littermates, were treated with 1,2-DAB, 35 mg/kg/day, or saline-control, for 3 weeks. 1,2-DAB induced motor weakness and PGNA irrespective of the genotype. Spna2-calpain breakdown products were not detected in mutant mice, which displayed a normal structure of the nervous system under saline-treatment. Intriguingly, treatment with 1,2-DAB reduced the abundance of the caspase-specific 120 kDa Spna2 breakdown products. Our findings indicate that degradation of Spna2 by calpain- and/or caspase is not central to the pathogenesis of 1,2-DAB axonopathy. In addition, the Spna2-CSD seems to be not required for the maintenance of the cytoskeleton integrity. Our conceptual framework offers opportunities to study the role of calpain-caspase cross-talk, including that of the protease degradomics, in models of axonal degeneration
