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.

Abstract

The attractive appearance of soap and its various benefits make it the choice of consumers. Transparent solid soap had a transparent appearance, so it was more attractive and produced softer foam than other soaps. This research aimed to create a good combination by utilizing tofu whey waste as a transparent soap ingredient with butterfly pea flower extract (Clitoria ternatea L.) to produce environmentally friendly soap. Utilization of tofu whey waste as an alternative to sucrose and butterfly pea flower extract as the active substance triclosan from natural ingredients that contain antibacterials and antioxidants. The results of this research showed that the addition of butterfly pea flower extract produces a yellowish-white soap preparation, with a dense texture, not transparent, and a distinctive slightly sweet soap aroma. The characteristics of soap preparations from whey waste with the addition of butterfly pea flower extract had a pH of 10.7, foam stability of 70%, water content of 29%, and did not irritate.
