Abstract

Vegetable waste, one of which is cabbage waste, has long been recognized as a cause of a significant environmental problems in traditional markets and must be addressed. However, cabbage waste can be used as an alternative energy source through the Microbial Fuel Cell process. The purpose of this study was to determine the potential of cabbage waste as a producer of bioelectricity and the storage time of cabbage waste that produces the largest bioelectricity using Microbial Fuel Cells. This research was conducted in February 2022 at Laboratory of Microbiology and Botany, Universitas Siliwangi. The study employed a completely randomized design (CRD), with treatment consisting of a control group (without storage), five storage treatments, namely: treatment 1 (2 days storage), treatment 2 (4 days storage), treatment 3 (6 days storage), treatment 4 (eight days storage), and treatment 5 (10 days storage). All treatments were repeated 4 times. A digital multimeter is used to determine the resulting electric current. The results indicated that the highest average total electric current generated was 0.022 mA from the 4 days storage treatment. The lowest average total electric current generated was 0.010 mA from the 10th days storage. These data indicate that the treatment of storage time of up to 4 days can increase the amount of electric current generated, then it decreases with increasing length of storage. It is influenced by several variables, including the growth phase of the bacterium, the availability of organic molecules, and the population of bacterium.

This type of research is a descriptive qualitative research. Data collection was carried out by giving learning outcomes instruments about vertebrate sub material which was done by 30 students of Class X math and science. Interview tests were also carried out with biology teachers and some students to get the validity of the data from the test questions that had been done. The learning outcomes test includes several indicators in the cognitive dimension, namely the cognitive knowledge domain consisting of K1 and K2, as well as the cognitive process domain consisting of C1-C5. Data were analyzed by finding the average value and the average score of each indicator in the cognitive domain. Based on the analysis results, the following data are obtained: 1) Dimensions of cognitive knowledge of students are better on factual knowledge; 2) Dimensions of cognitive processes that are mastered by students are at C1, while those less mastered by students are at C4; 3) Mastery of the concept of students in vertebrate sub material, namely material that is considered easy by students is general material because it relates to everyday life, including the understanding of vertebrates, discussion of animal pisces, and material about reptiles; 4) The difficulty of students in learning vertebrate sub material is in terms of deepening the material, because of the many types of vertebrate animals that must be mastered by students. And in terms of analyzing various kinds of vertebrate animals, it makes it hard for students to understand the form of story problems about vertebrate animals that exist in everyday life.Keywords: Cognitive Knowledge; Cognitive Process; Vertebrate Sub Material

Abstract

The batik industry in Indonesia has an IKM (Small and Medium Industry) scale so that it does not yet have adequate waste treatment. In the long term, waste is disposed of directly into the environment which can damage aquatic ecosystems and harm human health. Textile wastewater has a complementary picture and has a deep color. One of the most dangerous heavy metals contained in textile waste is hexavalent chromium (Cr(VI)). Several ways can be done to reduce hexavalent chromium (Cr(VI)) by bioremediation. Based on the results of the literature review, it shows that the bioremediation agents from single isolate microorganisms that are most effective in degrading chromium with high efficiency are Bacillus subtilis and Pseudomonas aeruginosa. The most effective consortium servers with constant reduction rates are the consortium of bacteria genus Mesophilobacter, Methylococcus, Agrobacterium, Neisseria, Xanthobacter, Deinococcus, Sporosarcina, and Bacillus by reducing BOD levels by 85.71%. The hexavalent chromium-degrading microorganisms are characterized by the presence of chromate reductase enzymes, mostly gram-negative bacteria, and a high growth rate.

Abstract

Critical thinking ability refers to an individual's capacity for in-depth thought due to the development of diverse thinking talents, including cognitive capabilities, in response to the acquired information. The purpose of the present study was to investigate the relationship between critical thinking skills, biology learning outcomes, and the visual learning style of students. The study used the correlational research method to ascertain the association between critical thinking abilities and biology learning outcomes among students with a visual learning style in class XI MIPA SMAN 6 Tasikmalaya. To this end, 40 students with predominating visual learning styles were selected from 137 students from class XI MIPA 4-7 at SMAN 6 Tasikmalaya. They were asked to fill in a learning style questionnaire with 23 statements. Moreover, they were asked to answer the nine-question evaluation of students' critical thinking abilities regarding biology topics. Students completed learning outcomes from the Year-End Assessment (PAT) grade XI MIPA in biological issues. Pearson product-moment correlation was employed to answer the research question. The result of the study indicated there is critical thinking ability had a limited association with learning outcomes in students who chose a visual learning approach. The correlation coefficient (R) of 0.365 and coefficient of determination (R2) of 0.133 attested to this. The findings revealed that both critical thinking skills and visual learning styles could predict learning outcomes.

Abstract

The most extensive textile export product and one of the nation's cultural legacies is batik cloth. However, regarding environmental quality, West Java's growing demand for batik production results in garbage contaminating the nearby waterways. The type of dye is where the harmful properties of batik waste originate. With descriptive qualitative methodologies and the Miles and Huberman model, this study intends to explain the various types of dyes used by SMEs producing batik in the batik centre region of the City and Tasikmalaya Regency and their impact for environmental health. The findings revealed that small and medium-sized enterprises (SMEs) engaged in the batik industry in Tasikmalaya City (Cipedes) utilized synthetic dyes such as indigosol, reactive Procion and Remazol, dispersion, and direct (mostly monoazo and diazo). In the meantime, batik artisans at the Tasikmalaya Batik Center (also known as Sukapura batik in Sukaraja) work with reactive Procion and Remazol (diazo), indigosol, jolawe fruit peel (Terminalia bellirica), soga jambal bark (Peltophorum pterocarpum), and tingi as natural dyes (Ceriops condolleana). The impact of used the different azo dyes can change the level of pH extremely, also improve the level of BOD, COD, TDS, and heavy metal such as chromium hexavalent ((Cr(VI)) in the waters

Abstract

Setiap peserta didik mempunyai kapasitas memori kerja yang berbeda. Banyaknya kegiatan dan kompleksitas materi menyebabkan berlebihnya kapasitas memori kerja peserta didik. Penelitian ini bertujuan untuk mengetahui beban kognitif peserta didik pasca pandemi covid-19 pada materi sistem indera. Penelitian dilakukan secara deskriptif kuantitatif. Teknik pengambilan sampel yaitu purposive sampling. Sampel penelitian sebanyak 35 peserta didik kelas XI MIPA 8 di SMAN 1 Singaparna. Instrumen yang digunakan yaitu soal uraian, angket dan soal pilihan majemuk. Hasil penelitian menyatakan bahwa pada Intrinsic Cognitive Load (menerima dan mengolah informasi) dengan nilai rata-rata 56,8 dengan kategori sedang. Kemudian Extranous Cognitive Load (usaha mental saat pembelajaran berlangsung) diperoleh nilai rata-rata 6,1 termasuk kategori sedang. Kemudian Germane Cognitive Load (pemahaman setelah seluruh materi sistem indera tersampaikan) diperoleh nilai rata-rata 54,7 termasuk kategori sedang. Sehingga dapat disimpulkan bahwa pembelajaran pasca pandemi covid-19 membuat peserta didik cukup terbebani, hal tersebut disebabkan perhatian peserta didik yang terbagi, ingatan peserta didik yang menurun, bahasa ilmiah sulit dicerna, penjelasan guru yang kurang jelas dan bahasa yang digunakan cenderung cepat, media ditampilkan kurang jelas dan hanya menggunakan gambar 2D saja. Kemudian peserta didik masih beradaptasi baik dari peserta didik lain, guru, dan materi pembelajaran.
