Abstract

The purpose of thisstudy was to determine the scientific literacy skills of first year student of biology education study program in Universitas Tribhuwana Tunggadewi. Subjects of this studyare50 students of biology education study program at academic year 2017/2018. Subjects of the study are a first year student when data collection conducted. Student scientific literacy skills was measured using test of scientific literacy skills (TOSLS) that consist of 28 test item to measuring two aspect of student scientific literacy skills. Collected data analyzed by descriptive quantitative methods to get a general information about student scientific literacy skills according to quantitative data. The result of the studyare the scientific literacy skills of first year student of biology education program generally classified in a low level. According to the result of the study, learning reorientation needed to enhancing students scientific literacy skills.

Abstract

Students in the study of science, need to pay attention to the nature of science. Science studied to develop the ability to think (minds on), skills (hands on) as well as the scientific attitude (heart on). Study Microbiology in Prodi TIP, University Tibhuwana Tunggadewi is about microorganisms. The writers conducted research related to environmental remediation efforts to harness the potential of bacteria indigen as an agent in the process of biodegradation. Research results are used as a reference in the preparation of the module. Through modules made based on the results of research, students are expected to develop 1) the ability to think that microorganisms can become agents in the process of rehabilitation of environmental pollution and can be isolated from the waste, develop 2) skills through practical biodegradation, and develop 3) attitudes scientific through concept which have been studied, in providing practical solutions to the problems of environmental pollution. The module aims to improve the efficiency and effectiveness of learning in the classroom either time, funds, facilities or personnel to obtain maximum results. Application of Microbiology learning which refers to the fusion module and science process skills through implementation of practical activities, is expected to be an alternative to creating a learning Microbiology which refers to aspects of the process, product and scientific attitude. The result is already done three stage preparation of teaching materials in the form of Microbiology module which refers to the model of research and development model of the 4-D (Thiagarajan, et al), includes define, design, and development. Results at the stage of defining the characteristics of students' analysis, task analysis, analysis of the concept and analysis of learning objectives. At the design stage to do the design and materials development, followed by the development phase, ie measurement of the feasibility of the modules have been prepared. Results obtained to measure the feasibility of the module is the achievement level of 85% by the expert development of teaching materials, 87% by material experts and 84% by the practitioner. The average yield of legibility student questionnaire amounted to 86.55%. The results of this validation consulted in order to repair the module. Keywords: Biodegradation in vitro, tanning pollutants, indigen bacteri

Abstract

Tujuan dari penelitian adalah untuk: 1) menguji pengaruh kecepatan aerasi terhadap kemampuan konsobakteri mendegradasi limbah cair kulit 2) menguji pengaruh waktu inkubasi terhadap kemampuan bakteri mendegradasi limbah cair. 3) menguji pengaruh interaksi antara kecepatan aerasi dan waktu inkubasi terhadap kemampuan bakteri mendegradasi limbah cair kulit. 4) menguji pengaruh efluen limbah cair kulit pasca perlakuan terhadap kelulushidupan ikan. Penelitian terbagi dalam beberapa tahap, yaitu penelitian pengaruh kecepatan aerasi dan waktu inkubasi terhadap kemampuan bakteri mendegradasi limbah cair kulit, pengaruh efluen limbah cair kulit pasca perlakuan terhadap kelulushidupan ikan. Hasil penelitian menunjukkan bahwa: kecepatan aerasi berpengaruh terhadap kemampuan bakteri mendegradasi limbah cair kulit, waktu inkubasi berpengaruh terhadap kemampuan bakteri mendegradasi limbah cair kulit, interaksi antara kecepatan aerasi dan waktu inkubasi berpengaruh terhadap kemampuan bakteri mendegradasi limbah cair kulit. Hasil uji hayati semua ikan yang diberi efluen limbah cair kulit mengalami kematian karena efluen masih berada di atas baku mutu yang ditetapkan pemerintah, sehingga disimpulkan efluen limbah cair berpengaruh terhadap kelulushidupan ikan.

Abstract

Sungai Badeg merupakan salah satu sungai kecil di kota Malang yang tercemar limbah pabrik kulit. Hasil pengukuran kualitas pada sampel air sungai Badeg menunjukkan kondisi yang tidak memenuhi baku mutu air yaitu TSS sebesar 400 ppm, BOD sebesar 331 mg/L, COD sebesar 544 mg/L, DO sebesar 3,6 mg/L dan kadar lemak sebesar 280 mg/L. Lemak merupakan salah satu bahan organik yang sulit untuk diuraikan secara alamiah. Biodegradasi diharapkan dapat menjadi solusi perbaikan kondisi perairan dengan cara memanfaatkan aktivitas bakteri indigen dengan karakteristik pendegradasi lemak. Kegiatan biodegradasi dilakukan dengan cara mengintroduksi bakteri indigen (yang telah diseleksi dari proses isolasi dan memiliki potensi pendegradasi paling tinggi diantara jenis isolat lain yang ditemukan) kemudian dikultur dan diinokulasikan kembali pada sampel air sehingga proses transformasi akan berlangsung lebih optimal. Biodegradasi dilakukan secara in vitro, dan menunjukkan perubahan yang signifikan terhadap perubahan kadar TSS menjadi 293,3 ppm, BOD sebesar 117,3 mg/L, COD sebesar 165,3 mg/L, DO sebesar 19 mg/L dan kadar lemak sebesar 0,02 mg/L. Biodegradasi dengan memanfaatkan bakteri indigen dapat menjadi alternatif dalam memperbaiki kualitas perairan.

Abstract

This study aims to develop an encyclopaedia of Dayak medicinal plants in biodiversity material for class X SMA/MA and determine the validity of the products developed. This research is a Research and Development (R&D) study that uses the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The research instruments are in the form of interview sheets, quality assessment questionnaires in the form of checklists using a Likert scale. The assessment was carried out by one material expert, one media expert, one science teacher and 25 grade X students. The results showed that the quality of the encyclopedias developed was in the very valid category according to material experts with a percentage of ideality of 98%; media experts 99% and science teachers 99%. The student response received a very valid category with an idealized percentage of 89.19%. Products that have been developed need to be implemented in order to determine the validity of the product, so that the encyclopedia product can be used as one of the learning resources for class X SMA / MA students.

Abstract

This research aims to determine the validity of the guided inquiry-based student worksheet on human excretory system material at junior high school level. This type of this research, namely development research using the modified ADDIE model. The research was conducted at SMP Negeri 16 Malang.  The data collection instruments include (1) LKPD validation questionnaire, which consists of material expert and media expert validation questionnaires, (2) user expert questionnaires, in this case teachers, and (3) student response questionnaires. Based on the assessment of material experts, they obtained a score of 80.9% (valid), media experts scored 96.3% (valid), teacher user experts scored 83.5% (valid), and small-scale student response scores were 70% (good), and large scale 68% (Good). The inquiry LKPD product is valid and can be continued with quasi-experiments to determine the effect of using the product on the results and learning process.
