Abstract

This paper focuses on the using of choral reading technique to the eleventh grade students’ reading mastery at SMA Negeri 1 Kasimbar. The writer applied quasi experimental research design and need pre-test and post-test to both experimental and control class. The pre-test was to know the level of students’ reading mastery ability before giving treatment while the post-test was used to know the result after giving treatment. There was a significant difference score of the post-test of the experimental class (1.495) and the control class (1.235). The level of significance was set up 0,05 with 40 degree of freedom ( (df) = Nx + Ny = 21 + 21 + 40). The result of data analysis indicates that tcounted (3,729) which was higher than ttable, it means that the hypothesis of the research was accepted. Thus, there was significant influence of using choral reading technique to the eleventh grade students at SMA Negeri 1 Kasimbar.

Abstract

Crude palm oil (CPO) merupakan minyak hasil olahan tandan buah segar menjadi minyak dari pabrik pengolahan kelapa sawit, masalah umum pada CPO adalah penurunan kualitas CPO akibat peningkatan konsentrasi asam lemak bebas (ALB). Tingginya kadar asam lemak bebas menyebabkan ketengikan, perubahan rasa dan warna pada minyak. Salah satu faktor penyebab meningkatnya jumlah asam lemak bebas pada minyak adalah hidrolisis dikarenakan jumlah kadar air yang tekandung dalam CPO. Penelitian ini dilakukan untuk mengetahui pengaruh kadar air, suhu dan lama penyimpanan terhadap kenaikan asam lemak bebas. Penelitian ini menggunakan metode Rangcangan Acak Lengkap (RAL) Faktorial dengan menggunakan tiga faktor (persentase air 0,35%, 0,40% dan 0,50%. Suhu 50 oC, 55 oC dan 60 oC. Lama penyimpanan 12 jam dan 24 jam). Hasil penelitian yang telah dilakukan menunjukkan bahwa semakin tinggi kadar air yang terkandung pada CPO maka semakin tinggi kenaikan kadar asam lemak bebasnya. Semakin tinggi perlakuan suhu yang diberikan maka kadar asam lemak bebas yang dihasilkan akan lebih rendah. Semakin lama penyimpanan CPO maka kadar asam lemak yang dihasilkan akan semakin tinggi. Hasil dari anova terhadap perlakuan menunjukkan bahwa perlakuan kadar air berpengaruh sangat nyata terhadap ALB, perlakuan suhu berpengaruh sangat nyata terhadap ALB dan perlakuan lama penyimpanan berpengaruh sangat nyata terhadap asam lemak bebas (ALB). Kata Kunci: Crude Palm Oil (CPO), Asam Lemak Bebas (ALB), kadar air, suhu, lama penyimpanan.
