Abstract

Lokasi penelitian terletak di Desa Geneng Duwur, Kecamatan Gemolong, Kabupaten Sragen, Jawa Tengah dengan jenis tanah Litosol. Lokasi penelitian terletak antara 7º23’10” LS sampai 7º23’17” LS dan 110º50’28” BT sampai 110º50’24” BT dengan ketinggian tempat antara 150 mdpl sampai 155 mdpl. Penelitian dilaksanakan bulan Februari 2010 sampai dengan November 2010. Tujuan penelitian : (1) Mengetahui pengaruh sistem tumpangsari yang diintegrasikan dengan ternak terhadap sifat fisik tanah; (2) Mengetahui pengaruh sistem tumpangsari yang diintegrasikan dengan ternak terhadap sifat kimia tanah. Rancangan penelitian yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok Lengkap yang terdiri dari 2 faktor, yaitu : faktor 1 : integrasi ternak sapi yang terdiri dari 4 taraf (I0 = tanpa integrasi ternak sapi (0 tahun); I1 = integrasi ternak sapi 1 tahun; I2 = integrasi ternak sapi 2 tahun; I3 = integrasi ternak sapi 3 tahun) dan faktor 2 : sistem tanam yang terdiri dari 3 taraf (K = sistem tanam monokultur dengan tanaman kacang tanah; J = sistem tanam monokultur dengan tanaman jagung; KJ = sistem tanam tumpangsari tanaman kacang tanah dengan jagung). Hasil Penelitian menunjukkan bahwa : (1) Sistem tumpangsari tidak berpengaruh nyata terhadap perbaikan sifat fisik tanah yang meliputi : berat jenis tanah, berat volume tanah, kapasitas lapang , porositas; integrasi ternak berpengaruh nyata terhadap perbaikan sifat fisik tanah yang meliputi : berat jenis tanah, berat volume tanah, kapasitas lapang , dan porositas tanah; (2) Sistem tumpangsari tidak berpengaruh nyata terhadap perbaikan sifat kimia tanah yang meliputi : bahan organik tanah, N total tanah dan pH tanah; integrasi ternak berpengaruh nyata terhadap perbaikan sifat kimia tanah yang meliputi bahan organik tanah, N total tanah dan pH tanah.

Abstract

CT scan is a reconstruction of tomographic slices of objects by a computer. The first application in the clinic was done in 1967 by the efforts of Godfrey Mounsfield in the Central Research Laboratory of EMI Ltd. in England. Its superiority compared with conventional tomography lies in the high power of resolution and its ability to distinguish soft tissues with 0.5% of the emission difference of X-ray, while with the conventional tomography the emission difference must be more than 5%. CT scan is very useful in both diagnostics and radiation therapy. Key Words: CT scan — conventional tomography — resolution power — radiation therapy —X-ray

Abstract

E-Journal memiliki peran penting dalam membangun budaya berbagi pengetahuan pada Univeristas Kristen Satya Wacana (UKSW). Mengacu pada pemahaman tersebut, maka kehadiran  ejournal di UKSW diletakkan sebagai basis mengembangkan dan distribusi pengetahuan yang  terdapat dalam kalangan sivitas akademika. Penelitian ini melihat bagaimana peran E-Journal sebagai basis pengembangan Knowledge sharing pada UKSW. Guna mendapatkan data dan informasi dalam penelitian ini, maka digunakan pendekatan kualititatif, melalui proses wawancara. Adapun temuan yangdiperoleh dalam penelitian ini adalah kehadiran E-journal memiliki peranan penting dalam mengembangkan budaya berbagi pengetahuan dengan memanfaatkan kehadiran teknologi informasi yang mendorong adanya efisiensi aksebilitas. Ejournal di UKSW memiliki peranan dalam melakukan diseminasi pengetahuan sebagia bentuk ineternalisasi terhadap pengetahuan yang ada.

Abstract

Mastering speaking skill is a must for vocational school students in order to face the globalization era in this modern world. However, the speaking competences mastered by the vocational school students are mostly still low and need to be increased. That is why this research tried to answer some problems: (1) the lack of ESP speaking materials for students of vocational schools; (2) what kinds of ESP speaking materials the 11th graders of vocational schools needed; (3) how were the ESP vocational speaking materials developed; and (4) how effective was the developed materials. The researcher adopted some steps in educational research and development proposed by Borg and Gall in Vocational School 1 Kendal. The researcher chose one class of eleventh graders that had 32 students in it. In conducting the study, the researcher observed the existing materials and interviewed the teacher for the need analysis. After that, the researcher developed the ESP vocational speaking materials, then conducted the expert validation to some experts and tests and gave questionnaires to the students. The researcher, then, calculated the product’s effectiveness by using t-test. It was found out that the product was  considered effective based on the t-test result and very good based on the questionnaire analysis. There were also some English speaking materials for vocational students, but unfortunately they were not in the form of ESP materials.
