Abstract

Xylanase can be used as an alternative material in the pulp bleaching process to reduce the use of chemicals in the paper industry. Bacillus subtilis is a type of bacteria that can produce xylanase. Xylanase characterization is needed to determine the maximum activity that will be used in the pulp bleaching process. This study aims to determine the xylanase characterization of Bacillus subtilis in terms of optimal pH, optimal temperature, carbon source, and optimal nitrogen source. The research material used was a pure culture of Bacillus subtilis bacteria obtained from the Biochemistry Laboratory of the Department of Chemistry, Faculty of Mathematics and Natural Sciences, Brawijaya University. The characterization of the xylanase enzyme was carried out using the RAL method. The results of characterization of the determination of pH, temperature, carbon source, and nitrogen xylanase source from Bacillus subtilis showed that the optimum conditions for xylanase were at pH 7 with a maximum activity of 5.085 U / mL; the optimum temperature at 40oC with activity 8.017 U/mL; maximum carbon source at a concentration of 15% (b/v) with activity 7.517 U/mL; and the optimum source of nitrogen with a concentration of 0.17% (b/v) with an activity of 4.815 U/mL.

Abstract

Mahasiswa baru di kampus yang berbasis pendidikan vokasi memiliki background pendidikan yang berbeda. Kebanyakan dari mereka berasal dari sekolah menengah atas atau sederajat yang jurusannya bukan IPA. Hal ini menyebabkan mata kuliah Mikrobiologi Dasar di semester satu termasuk ke dalam mata kuliah yang sulit dipahami oleh mahasiswa dengan background di luar IPA. Selain itu, minimnya lembar kerja mahasiswa yang bisa mengasah daya pikir mereka adalah penyebab rendahnya hasil belajar pada mata kuliah ini. Hasil observasi menunjukkan banyak mahasiswa yang cukup kesulitan dalam memahami materi nutrisi mikroorganisme. Tujuan dari penelitian ini adalah untuk mengembangkan Lembar Kerja Mahasiswa (LKM) pada materi Nutrisi Mikroorganisme berbasis High Order Thinking Skill (HOTS). Model pengembangan yang digunakan dalam penelitian ini adalah 4-D dari Thiagarajan dengan mengadopsi tiga tahapan yaitu Define (Pendahuluan), Design (Perencanaan) dan Develop (Pengembangan). Hasil pengembangan menunjukkan bahwa 78% LKM dinilai layak. Kebahasaan LKM sebesar 72,5% dikategorikan layak dan penyajiannya sebesar 76,6% dikategorikan layak. Kegrafikan LKM sebesar 82,5% dikategorikan sangat layak. Hasil uji keterbacaan dari LKM adalah 71,78% dengan kriteria layak dan respon mahasiswa dalam menggunakan LKM, 90% menyatakan sangat baik.

Abstract

Biological evaluation tools are very important. The current reality is that biology evaluation tools are rarely used in learning because of limited tools, materials and time. One of the efforts made is to develop a computer/PC-based KUMAL (Kuis Animalia) game application. The aim is to determine the feasibility of the KUMAL game developed as a learning evaluation tool on animalia material. The research was conducted using Research and Development (R&D) research and development methods. The samples in this study were 3 material experts, 3 media experts and 3 IT experts. The validation results from this study are 84% with a very feasible category from the material validator, 83% with a very feasible category from the media validator and 83% with a very feasible category from the IT validator. The conclusion of this study is that the KUMAL game is feasible to be used as an evaluation tool for biology learning in animalia material for class X SMA/MA.

This research aims to identify the effect of RUSA (Ruang Siswa), an Android-based learning media with appypie application, and figure out the validity of the media to enhance motivation and learning outcome of grade X students in Animalia material. The method of this research was Pre-experimental. The type of (R&D). This development model applied Borg & Gall procedure which was limited up to the seventh step, that is, product revision. Based on the hypothetical test of the effect of RUSA (Ruang Siswa) on students’ motivation using t test, and the effect of RUSA on learning outcome using Ancova test, it was obtained that the significance value of RUSA (Ruang Siswa) was 0.000. Since the significance value was 0.000 < 0.05, H0 was rejected and H1 was accepted. Based on the result of validity test by media experts, the validity percentage was 74.50% classified as valid criteria, Material expert was 77.03% with classified as valid criteria, Language expert was 83.33% classified as very valid criteria. In addition, the data from students showed the percentage of 89.14% classified as valid criteria, and from the Biology teachers was 75.33% classified as valid criteria. Therefore, it is clear that there was an effect of using RUSA (Ruang Siswa) on students’ motivation and learning outcome. Referring to the validity result, RUSA (Ruang Siswa) is valid to use.

Abstract

Limbah whey dari produksi pembuatan tahu dapat menimbulkan pencemaran lingkungan jika dibuang begitu saja, sehingga membutuhkan penanganan melalui pengolahan menjadi produk yang bernilai ekonomis seperti sabun padat. Tujuan penelitian ini adalah memformulasi sabun padat berbahan baku limbah whey serta melakukan uji organoleptik, pH, dan tinggi busa. Formulasi (%) antara limbah whey tahu dan olive oil adalah F1 (20 dan 0,5), F2 (20 dan 1) dan F3 (20 dan 2). Diawali dengan pembuatan sabun padat menggunakan metode eksperimental, menguji tinggi busa melalui uji deskriptif dengan metode observasional analitik, dan uji organoleptik dan pH melalui uji deskriptif. Hasil penelitian ini adalah semua formula sabun padat memiliki efektivitas yang baik, ketinggian busa telah memenuhi SNI 06-4085-1996, tetapi memiliki pH yang lebih besar dari pH SNI 06-4085-1966. Sediaan sabun padat yang terbaik adalah formula 1 (F1), karena memiliki nilai pH yang mendekati nilai pH SNI tersebut.
