Abstract

Penelitian ini bertujuan untuk meningkatkan kualitas proses pembelajaran dan hasil kemampuan menulis teks eksposisi melalui strategi Think Talk Write (TTW) pada siswa kelas VIII.7 SMP Negeri 30 Makassar. Jenis penelitian yang digunakan adalah penelitian tindakan kelas, dengan subjek penelitian siswa kelas VIII.7 SMP Negeri 30 Makassar berjumlah 36 siswa yang terdiri dari 18 siswa perempuan dan 18 siswa laki-laki. Desain penelitian yang digunakan adalam model Kemmis & Mc. Taggart dengan empat tahap yaitu, perencanaan, pelaksanaan, observasi, dan refleksi. Penelitian ini dilaksanakan dalam satu siklus yaitu siklus II yang sudah terbukti keberhasilannya sehingga tidak dilanjutkan kepada siklus selanjutnya. Siklus II, terdiri atas empat kali pertemuan sebagai perlakuan. Teknik pengumpulan data menggunakan tes, dokumentasi, dan observasi dalam bentuk catatan lapangan. Teknik analisis data yang digunakan adalah statistic deskriptif dengan mencari nilai rata-rata. Hasil penelitian menunjukkan bahwa penggunaan strategi Think Talk Write (TTW) dapat meningkatkan kemampuan menulis teks eksposisisi kelas VIII.7 SMP Negeri 30 Makassar. Peningkatan sikap dan keaktifan siswa pada saat proses pembelajaran teks eksposisi meningkat dari pratinakan/kondisi awal berada dalam kondisi kurang, pada siklus II menjadi kategori baik. Pada pratindakan/kondisi awal nilai rata-rata kemampuan menulis siswa 51,19. Siswa yang mencapai nilai KKM (>75) sebayak sebanyak tujuh siswa (20%), sedangkan peningkatan nilai rata-rata kemampuan menulis teks eksposisi pada siklus II meningkat sebesar 83,11%.

Abstract

Lactic Acid Bacteria (LAB) produces natural antimicrobial compounds that can inhibit and prevent the growth of spoilage bacteria. LAB can be isolated from fermented food such as pickles which fermented at  cool temperature. The objective of this research to isolate and to obtain  LAB from yellow bamboo (Dendrocalamus asper) shoots pickles that has antimicrobial activity against Escherichia coli  and Staphylococcus aureus.  It was made by submerged yellow bamboo shoots in 2.5%   of brine solution and kept into sealed container then fermented at chiller (15oC) temperatures for 10 days. LAB was isolated using MRS agar and identified base on their morphological, physiological and biochemical characteristics. The result showed that LAB isolates identified as Lactobacilli and had antimicrobial activity against Escherichia coli  and Staphylococcus aureus.  All Lactobacilli (21 isolates) that was isolated from fermentation at 15oC were homofementative.

Abstract

Yellow bamboo shoot is a popular food material especially in Semarang because it is used as filling for lumpia (authentic food of Semarang). Beside used as filling, yellow bamboo shoot commonly known by Indonesian people. Considering bamboo shoot often processed into fermented traditional food, yellow bamboo shoot also potential to be examined as source of fermented food producing lactic acid bacteria. Lactic acid bacteria still become the most beneficial microorganisms associated with gastrointestinal system and moreover for obesity diet. The aim of this research is to study the probiotic potential of lactic acid bacteria produced from yellow bamboo shoot fermentation in 2.5% and 5% brine under room temperature (30 °C). From isolation, 22 single colonies obtained from 2.5% brine and 27 isolates obtained from 5% brine. The morphology and physiology analysis resulted in Lactobacillus and Streptococcus genus. All isolates were tested subsequently for probiotic potential. Based on the result, more than 50% identified isolates have probiotic potential.
