Abstract

Penelitian dilakukan dengan tujuan untuk meningkatkan hasil belajar siswa kelas V SDNSiwalankerto 1 Surabaya pada mata pelajaran Bahasa Indonesia melalui model pembelajaran Project Based Learning (PjBL). Penelitian ini ialah penelitian tindakan kelas (PTK) yang dilakukan dalam dua siklus.Subjek dalam penelitian ini yaitu siswa kelas V SDN Siwalankerto 1 Kota Surabaya, yang berjumlah 21siswa, dan terdiri dari 11 siswa laki-laki dan 10 siswa perempuan. Teknik pengumpulan data padapenelitian ini yaitu dengan menggunakan pretest dan postest untuk mengukur hasil belajar siswa.Berdasarkan penelitian dapat diketahui hasil belajar siswa pada mata pelajaran Bahasa Indonesiamengalami peningkatan mulai dari pra siklus dengan ketuntasan belajar sebanyak 14%, kemudian pada siklus I meningkat menjadi 62% dan pada siklus II meningkat menjadi 95%. Data kemudian dianalisis menggunakan metode deskriptif kualitatif dan deskriptif kuantitatif. Dari siklus I ke siklus II terjadi peningkatan sebesar 33%. Dari penghitungan data dapat diketahui penggunaan model Project BasedLearning dapat meningkatkan hasil belajar siswa kelas 5 SD.

Abstract

The high water absorption of concrete causes the concrete to easily experience cracking and damage. One way to increase the durability of concrete is by adding microbes which can fill the micro cavities in the concrete with the resulting Calcium Carbonate (CaCO3) deposits. However, the weakness of using microorganisms is that they are unable to withstand high hydration heat. Therefore, by varying the temperature in this research, it is possible to determine the effect of the metabolism of the bacteria produced. This research was carried out to avoid damage by creating a hydrophobic and self-healing layer which helps increase the durability and strength of the concrete. The concrete sample made resembles a cube measuring 5 cm x 5 cm x 5 cm. The manufacturing materials are Portland cement, Otawa sand, distilled water and a mixture of E. coli bacteria. Heating was carried out using an oven at temperatures of 30, 60, 90, and 120 oC. Characterization testing was carried out using a Cpmreson machine, XRD and contact angle testing.
