Abstract

This study is experiment research with control group pre test- post test design and aimed to examine the influence of PQ4R strategy and Refutation Text, school level, and students mathematical prior knowledge toward achievement and enhancement of students mathematical communication ability and Self Regulated Learning. Subject of study as much as 241 students of class X from three Public Senior High Schools from high, medium and low school level. Research instrument consist of one set of students mathematical communication, and one set of students Self Regulated Learning scale. Data analysis use Kosmogorov-Smirnov Test (Tes-Z), Test Leven, Test-t, ANOVA one-way and two-way, Post Hoc Test (Scheffe) and also Chi-Square Test. The study found that learning with PR4R strategy accompanied by Refutation Text Reading give consistent influence compared with conventional learning influence whether is viewed as a whole, based on school level as well as mathematical initial knowledge. In addition, the study also found: (1) there is no interaction between learning (PQ4R) accompanied by Refutation Text reading and conventional) and school level toward (a) students mathematical communication and (b) students Self Regulated Learning; (2) there is no significant interaction between learning and students mathematical prior knowledge toward (a) students mathematical communication ability and (b) students Self Regulated Learning; and (3) there is association between students mathematical communication ability and students Self Regulated Learning.

Abstract

ABSTRAKKondisi ekologis saluran pencernaan  kondusif berpengaruh terhadap kelancaran metabolisme tubuh.  Keseimbangan mikroflora hidup pada saluran pencernaan itik sangat membantu kelancaran pencernaan nutrien ransum menjadi zat yang lebih sederhana.  Kitosan merupakan jenis serat hewan yang sangat cocok untuk menunjang kehidupan bakteri jenis menguntungkan dalam saluran cerna.  Tujuan penelitian adalah melihat perkembangan mikroflora saluran pencernaan dengan pemberian kitosan.  Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan  4 perlakuan dan 5 ulangan.  Masing-masing ulangan terdiri dari 2 ekor itik sebagai satuan percobaan.  Perlakuan adalah R0 = 0% kitosan, R1 = 0,5% kitosan, R2 = 2% kitosan dan R3 = 2,5% kitosan. Peubah yang diukur adalah jumlah total populasi mikroba, jumlah Salmonela dan jumlah E coli saluran pencernaan itik.  Hasil penelitian menunjukkan bahwa pemberian kitosan 0,5% dan 2% memberikan peningkatan  rataan jumlah total mikroba (TPC) pada saluran cerna.  Kitosan juga  menurunkan jumlah E coli saluran cerna serta kandugan Salmonella sp negative(<10 2  ) Kata kunci: Kitosan, mikroflora, saluran cerna, itik Tegal  ABSTRACT Conducive ecological conditions of the digestive tract affect the smooth metabolism of the body. The balance of living microflora in the digestive tract of ducks greatly helps the smooth digestion of nutrients into simpler substances. Chitosan is a type of animal fiber that is potential to support the life of beneficial type bacteria in the gastrointestinal tract. The aim of this research is to see the development of microflora of gastrointestinal tract by giving chitosan. The study used Completely Randomized Design (RAL) with 4 treatments and 5 replications. Each replication consists of 2 ducks as experimental units. The treatment was R0 = 0% chitosan, R1 = 0,5% chitosan, R2 = 2% chitosan and R3 = 2.5% chitosan. The measured variables were total microbial population, number of Salmonella and amount of E coli of duck digestive tract. The results showed that giving of chitosan 0,5% and 2% give increase of total amount of microbe (TPC) in gastrointestinal tract. Chitosan also decreases the amount of E coli gastrointestinal tract and Salmonella sp negative (<102) Keywords: chitosan, microflora, gastrointestinal tract, Tegal duck
