Abstract

In addition to carbohydrates, rice contains other minerals that function to growth and development of vital human organs. On the other hand, the content is influenced by genetic and milling processes. Indonesian Centre of Rice Research (ICRR) has genetic collection resistant to strains of the brown plant hopper (BPH). Genotypes were studied to assemble the pest-resistant varieties with high iron (Fe) and zinc (Zn) content. This study aims to determine the BPH-resistant lines that had high and stable Fe and or  Zn content. The study was conducted in XRF Laboratory, ICRR Sukamandi, West Java in 2015. Fe and Zn were determined by using XRF machine with a system of performance-based X-ray. Total 20 rice lines that resistant to BPH was used Fe and Zn content on brown and polished rice were evaluated duplo. The results showed that milling generally decreased the content of Fe and Zn at rate 56.31% and 20.54%, respectively. The highest Fe content was found in BP19564b-WBC-1-1-4-3 (12.25 ppm), while the highest Zn content in BP19564b-WBC-1-9-8-3 (26.35 ppm). Genotype BP19564b-WBC-1-9-4-2 and BP19564b-WBC-1-9-8-3 exhibited the lowest in reduction Fe and Zn content, respective, from brown to polished rice.

Abstract

The purpose of this study was to find out the difference in effectiveness between CWT and cold compresses against phlebitis degrees in patients who were infused in hospitals. Dustira Cimahi. Experimental quasi-research method with two groups pretest and posttest design approach, with a sample number of 44 patients using purposive sampling, intervention group using CWT and control group using cold compress. The results showed a difference in phlebitis degree score before and after cold compresses (pretest 2.32 and posttest 1.68) which showed a decrease in phlebitis degree score. In the group that used CWT, there was a difference in phlebitis degree score (pretest 2.41 and posttest 1.32), with p= 0.000, this showed a decrease in phlebitis degree score and the significance of the difference in average phlebitis degree score before and after intervention. The mean value of the intervention and control group is negative with the difference in phlebitis degrees between the intervention group and the control group (p=0.026). A decrease in the degree of flebititis in the CWT group occurred in the third treatment, while in the cold compress group occurred in the fifth treatment. The results of both interventions were effective in lowering phlebitis, but CWT was more effective when compared to cold compresses. It is recommended that nurses can be used as one of the evidance-based nursing that serves as the rational basis for the implementation of Contrast Water Therapy as an independent nursing intervention to reduce the degree of phlebitis quickly without causing additional accumulation of edema. Based on the results of research and discussion, the conclusions in this study are both interventions both CWT and cold compresses are equally effective in lowering the degree of phlebitis, but CWT interventions are more effective and faster to lower the degree of phlebitis in patients who are infused when compared to cold compresses.

Abstract

The purpose of this study is to determine the critical thinking skills of students in class VIII B of SMP Negeri 2 Ciamis, Indonesia which emerged through a controversial issue model in social studies learning. This study used a qualitative and quantitative approach. 33 students in class VIII B were taken as the subject of this study. The four stages of classroom action research were planning, action, observation, and reflection which carried out in two cycles, and each cycle consists of two meetings. The data collection techniques used tests, observations, documentation, and field notes. The data analysis techniques used qualitative and quantitative descriptive analysis. The results of the study were: 1) social studies learning by means of a controversial issue model includes four steps, namely: (a) the teacher or student presented a case or issue related to the learning to be carried out, (b) the teacher made a group of students so that they were able to discuss problems or issues that had been presented. (c) the group representatives either as the defenders or the attackers of an opinion on a controversial issue, (d) then the teacher and students concluded and gave suggestions from the activity. 2) the implementation of the controversial Issue model in social studies learning could improve students' critical thinking skills. This can be seen from the average ability developed by each action reached 12.8 which was enough categories in cycle I, then changed to 16.8 which was good categories in cycle II. Keywords: Critical Thinking, Controversial Issues, Social Studies LearningABSTRAKTujuan dari penelitian ini adalah untuk mengetahui kemampuan berpikir kritis siswa kelas VIII B SMP Negeri 2 Ciamis yang muncul melalui model controversial issues dalam pembelajaran IPS. Penelitian ini menggunakan pendekatan kualitatif dan kuantitatif dengan subjek penelitian siswa kelas VIII B SMP Negeri 2 Ciamis yang berjumlah 33 orang. Empat tahapan penelitian tindakan kelas meliputi: perencanaan, tindakan, observasi, dan refleksi. yang dilaksanakan dalam dua siklus, dan tiap siklus terdiri dari dua pertemuan. Teknik pengumpulan data menggunakan tes, observasi, studi dokumen dan catatan lapangan. Teknik analisis data menggunakan analisis deskriptif kualitatif dan kuantitatif. Hasil penelitian yang di peroleh adalah: 1) Bahwa pembelajaran IPS dengan menerapkan model controversial issue meliputi empat langkah yaitu : (a) guru atau siswa menyodorkan suatu kasus atau isu yang berkaitan dengan pembelajaran yang akan di laksanakan, (b) guru membentuk kelompok siswa agar mampu membahas masalah atau isu yang telah di sajikan. (c) perwakilan kelompok dapat menjadi pembela atau penyerang suatu  pendapat tentang isu kontroversial di sertai alasan. (d) kemudian guru dan siswa menyimpulkan serta memberi saran terhadap pembelajaran yang telah terjadi. 2) Implementasi model controversial Issue dalam pembelajaran IPS mampu meningkatkan kemampuan berpikir kritis siswa. Hal ini dapat dilihat dari rata-rata kemampuan yang dikembangkan setiap tindakan mencapai 12,8 berkategori cukup pada siklus I, kemudian berubah menjadi 16,8 berkategori baik pada siklus II. Kata kunci : Berpikir Kritis, Controversial Issues, Pembelajaran IPS
