Abstract

Recent development in fermentations for bioethanol production were focused three factors, i.e. abundance and cheap substrates,superior yeast fermenting the substrates, and simultaneous saccharification and fermentation (SSF) technology.Nowadays national and world bioethanol production still depend on sugar cane and starchy materials.This research aims to determinate the optimum simultaneous saccharification and fermentation (SSF) conditions to identify the performance of local strain Saccharomyces cerevisiae recombinant [GLO1] in the producing bioethanol from starch.The optimum conditions for SSF process are in a media composition containing glucose 2% (w/v), starch 5% and at aeration rate 50 rpm.At these optimum conditions Saccharomyces cerevisiae recombinant [GLO1] produce 25.36% (v/v) bioethanol at day-20 of the fermentation process design.

Abstract

Penelitian bertujuan untuk mengetahui perbedaan pertumbuhan, viabilitas dan produksi kokon ulat sutera Bombyx mori L yang diberi pakan alami dan pakan buatan berpengawet. Penelitian ini menggunakan ulat sutera Bombyx mori L. ras 301 hasil silangan ras Jepang dengan ras Cina yang diperoleh dari Pusat Produksi Ulat Sutera Temanggung. Variabel yang diukur selama penelitian adalah rata-rata pertambahan bobot badan, viabilitas, jumlah kokon,bobot kokon utuh dan kokon kosong. Data yang diperoleh dianalisis menggunakan uji t. Hasil penelitian menunjukkan bahwa pemberian pakan buatan dan pakan alami menghasilkan perbedaan nyata terhadap pertumbuhan bobot badan, viabilitas, jumlah kokon, bobot kokon utuh dan kokon kosong. Pertumbuhan ulat sutera yang diberi pakan buatan berpengawet lebih rendah dibanding pertumbuhan ulat sutera dengan pakan alami, akan tetapi sebaliknya viabilitas dan produksi kokon lebih baik. The aim of this research was to compare the difference of growth, viability and cocoon production of silkworm (Bombyx mori L) fed by natural food and preserved artificial food. The artificial food were prepared with the addition of preservatives. The research used the silkworms Bombyx mori L variant 301 resulted from the crossbreeding between the Japanese silkworms and the Chinese silkworms obtained from PPUS, Temanggung. The parameters observed were the average body weight gain, the viability and the production of cocoon (the weight of the whole cocoon and the weight of empty cocoon). The data obtained was analyzed using t-test. The result confirmed that the artificial feeding and the natural feeding showed a significant difference in the increase of body weight, the viability and the production of cocoons of Bombyx mori L. It was concluded that the growth of body weight of silkworms fed with artificial feeding was lower than those fed with natural feeding, but higher in the viability and the cocoon production.

Abstract

Abstrak Penelitin ini bertujuan untuk mengetahui pengaruh pendekatan CTL berbasis eksperimen terhadap hasil belajar kognitif dan sikap ilmiah. Desain dari penelitian ini adalah control group pre-test post-test desain. Sampel diambil secara pusposive sampling dan didapatkan kelas VIII D sebagai kelas eksperimen dan kelas VIII C sebagai kelas kontrol. Data penelitian ini adalah data nilai posttest dan data observasi sikap ilmiah peserta didik. Hasil penelitian ini menunjukkan bahwa rata-rata nilai posttest kelas eksperimen adalah 76,84 dan kelas kontrol 65,97. Hasil analisis korelasi biserial 0,71 dan koefisien determinasi 50,2%. Berdasarkan observasi, hasil analisis korelasi spearman adalah 0,50 untuk sikap ingin tahu, 0,48 untuk berpikir kritis, 0,56 terbuka, dan 0,58 kerja sama. Hasil koefisien determinasi adalah 25% untuk rasa ingin tahu, berpikir kritis 23,04%, terbuka 31,36%, dan kerja sama 34,81%. Abstract This experiment aims to determine the effect of CTL-based experimental approach to the cognitive learning and scientific attitude. The design of this study was the control group pre-test post-test design. Samples taken pusposive sampling and got VIII D as experimental class and class VIII C as the control class. This research data is the value of data and observation data posttest learners' scientific attitude. The results showed that the average value was 76.84 posttest experimental class and control class 65.97. Results of correlation analysis biserial 0.71 and coefficient of determination of 50.2%. Based on observations, the results of Spearman correlation analysis was 0.50 for curiosity, 0.48 to think critically, open 0.56, and 0.58 cooperation. The coefficient of determination was 25% f or curiosity, critical thinking 23.04%, 31.36% open, and cooperation 34.81%.

Abstract

Penelitian ini dilatar belakangi dari kesulitan siswa dalam Pelajaran Bahasa Arab, pada dasarnya dalam pembelajaran bahasa asing, kosa kata merupakan salah satu dari tiga unsur bahasa yang sangat penting dikuasai. Penelitian ini bertujuan mengembangkan buku ajar kosa kata dengan media lagu di Mts Hidayatus Sholihin serta melihat efektifitas dari buku yang dikembangkan.Tujuan penelitian ini adalah: 1) Pengembangan Bahan Ajar Mufrodat dengan metode bernyanyi untuk kelas 7 di Mts Hidayatus Sholihin Gurah Kediri. 2) Efektivitas penerapan Bahan Ajar Mufrodat dengan metode bernyanyi untuk kelas 7 di Mts Hidayatus Sholihin Gurah Kediri. Peneliti menggunakan metode penelitian R&D yang dikembangkan oleh Borg and Gall yang terdiri dari 10 langkah dan metode pengumpulan data yang digunakan dalam penelitian yaitu wawancara, angket dan tes.Penelitian ini menunjukkan bahwa: 1) Hasil pengembangan produk berupa buku pendamping untuk pembelajaran Bahasa Arab siswa kelas 7 yang berisi kosa kata yang disusun sesuai dengan nada lagu. Adapun hasil validasi dari para ahli untuk menilai produk sebagai berikut: hasil dari ahli materi  83, 07 %, hasil dari ahli media 93, 84 %, dan dari praktisi pembelajaran bahasa arab 98, 33 % berdasarkan paparan data tersebut maka pembelajaran mufrodat dengan metode bernyanyi dinyatakan sangat baik. 2) hasil Uji-T, hasil t-hitung antara nilai pretest dan post test sebesar 3, 262 sedangkan hasil t-tabel sebesar 2, 015. Maka dapat disimpulkan t-hitung > t-tabel, maka Ho ditolak dan Ha diterima yaitu terdapat perbedaan hasil pembelajaran mufrodat di kelas 7 Mts Hidayatus Sholihin sebelum menggunakan metode bernyanyi dengan sesudahnya. Dari nilai eksperimen tersebut dapat disimpulkan metode bernyanyi dalam pembelajaran mufrodat  untuk kelas 7 di Mts Hidayatus Sholihin di nyatakan “efektif”.

Abstract

In this study, the researchers focus on implementing mahārah kalām book at Al-Azhar Arabic course, Pare. This study used a descriptive qualitative approach. The data were collected using observation, interviews, and documentation. Miles and Huberman techniques were used to analyzing the data. The results reveal that: first, the textbooks used are books compiled directly by the founder of the course. There are al-muhādaṡah 1, mufradāt 1500 vocabularies, and al-qawāid al-taysīr. Second, in the learning process, the teacher used various methods, namely conversation, singing, question answering, and memorization. Third, the daily evaluation of speaking skills is in the form of a test that requires the students to make a story, which should be memorized and then practiced in front of the class. Finally, the final evaluation covers all the materials learned within 5 -10 minutes.
