PROSES PEMBELAJARAN BIOLOGI PADA MATERI SISTEM PEREDARAN DARAH MANUSIA DI KELAS VIII SMP NEGERI 3 RAMBATAN

<p><em>Leaning process can influence students’ achievement. The lack of students’ understanding on the particular materials could decrease students’ achievement. The purpose of this research is to evaluate the leaning process of biology in human circulator system at the eight grade of Junior High School (SMP) 3 Rambatan covering the lesson plan, implementation of learning proces, evaluation, and students’ learning outcome. This researh was descriptive using qualitative approach. It was conducted at SMP 3 Rambatan. Data were collected using IPKG on lesson, interview, document, and field notes. The reseach shows as follows: (1)  the format of lesson plan used by the teachers has fulfilled the IPKG and could be categorized into good; (2) the learning process had not yet referred to the IPKG but could be classified as good and enough category; (3) the evaluation of learning process had not referred to IPKG; (4) students’ learning activities were still low; and (5) students’ learning outcome were unsatisfactory.</em><em></em></p><strong>Kata Kunci</strong>: proses pembelajaran biologi, sistem peredaran darah manusia, aktivitas   siswa, hasil belajar.

PEMAKAIAN PREBIOTIK UBI JALAR KUNING (Ipomoea batatas L) DAN PROBIOTIK Lactobacillus casei PADA PEMBUATAN SUSU FERMENTASI SINBIOTIK

<p>This research study about use of prebiotic <em>Ipomea batatas</em> L. and probiotic  <em>Lactobacillus casei</em> at milk fermentation. The usage of simbiotic increase, recentely, especially, for husbandarys products, such as milk fermentation the purpose of this study was to find out the best composition of prebiotic  <em>Ipomoea batatas</em> L and probiotic <em>Lactobacillus casei</em> given in the process of simbiotic milk fermentation. The method used for this experiment was random cluster, factorial 4 x 3 with 3 times of re-treatment, and was analyzed with BNT and BNJ testing. “A” factor was the use of prebiotic <em>Ipomoea batatas</em> L. (0%, 7,5 %, 15 %, 22,5 %), and “B” factor was the use of probiotic <em>Lactobacillus casei</em> (2%, 3%, 4 %) the component measure were BAL , water and TTA the result of this study was shown that the best use of prebiotic <em>Ipomoea batatas</em> L and probiotic <em>Lactobacillus casei</em> in the process of symbiotic milk fermentation were in the composition of highest BAL : 21,40 x 10⁸ cfu/ml. the highest TTA and water were 0,21 % and 71,98 22,5 %  of prebiotic <em>Ipomoea batatas</em> L.  and 4% probiotic Lactobacillus casei consentrate.</p><p> </p><span>Key words:</span><strong> </strong><span>prebiotic, </span><em>Ipomea batatas</em><span> L., probiotic,  </span><em>Lactobacillus casei</em><span>, milk fermentatio</span>
