Abstract

This research overcomes the problem of traditional assessments in Plane and Spatial Geometry courses which are often unable to measure students' mathematical spatial abilities effectively. Thus, the aim of this research is to develop and evaluate a computer-based assessment instrument using Articulate Storyline which is designed to improve the quality and efficiency of evaluation in this course. The research methodology follows the ADDIE development model, starting with an analysis of the needs of 2nd semester students of the Mathematics Department, FMIPA, Medan State University (UNIMED), followed by design, development, implementation and evaluation. The research results show that this instrument has a high level of validity and reliability, with the majority of students showing good skills in using digital devices and supporting network access. This instrument also received positive responses from students and lecturers, demonstrating its effectiveness in increasing engagement and understanding of the material. In conclusion, this computer-based instrument succeeded in improving the quality of evaluation, although this research was limited to several chapters and one institution. It is recommended that future research expand the scope of materials and implementation contexts to test the generalizability of results as well as overcome network access barriers, opening opportunities for further innovation in academic assessment.

Abstract

Salah satu upaya meningkatkan kemampuan berpikir kritis siswa adalah melalui pengembangan E-LKPD. Penelitian ini bertujuan untuk mengembangkan E-LKPD Interaktif berbantuan Liveworksheets yang valid, praktis dan efektif yang dapat digunakan dalam meningkatkan kemampuan berpikir kritis Siswa. Kami menggunakan model ADDIE untuk menghasilkan E-LKPD yang idea dan menstimulus siswa untuk berpikir kritis. Kami melibatkan sebanyak 35 siswa SMA Negeri 1 Hamparan Perak. Selanjutnya, kami menggunakan instrimen berupa lembar validasi terhadap angket respon siswa dan guru, lembar validasi terhadap media dan materi, angket respon guru dan siswa dan instrumen tes kemampuan berpikir kritis. Hasil penelitian menunjukkan bahwa E-LKPD berbantuan liveworksheets memenuhi kriteria valid, praktis, dan efektif. Hal ini menunjukkan bahwa E-LKPD memberikan dampak yang signifikan terhadap pemikiran kritis siswa dan dapat dijadikan sebagai acuan dalam proses pembelajaran.

Abstract

Penelitian ini bertujuan untuk mengetahui hubungan antara motivasi belajar dengan prestasi belajar matematika Siswa SMA Negeri 1 Sunggal kelad XI5. Motivasi belajar merupakan salah satu faktor yang sangat penting dalam mempengaruhi keberhasilan siswa dalam proses pembelajaran. Prestasi belajar siswa dipengaruhi oleh berbagai faktor, salah satunya adalah motivasi. Oleh karena itu, penelitian ini diharapkan dapat memberikan gambaran sejauh mana motivasi belajar memengaruhi prestasi belajar matematika. Metode penelitian yang digunakan adalah Pendekatan Kuantitatif. Data dikumpulkan melalui angket dan hasil tes prestasi matematika siswa. Analisis data yang digunakan pada penelitian ini adalah uji analisis regresi sederhana. Hasil penelitian ini menunjukkan seberapa besar pengaruh motivasi belajar terhadap prestasi belajar matematika siswa SMA 1 Sunggal kelas XI 5 dapat dilihat dari hasil R Square yang dalam penelitian ini didapat 0,448 sehingga diperoleh KD = 44,8 %, artinya sebesar 44.8% faktor yang mempengaruhi prestasi belajar siswa, sedangkan 55,2 % dipengaruhi faktor lain.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh model pembelajaran Discovery Learning terhadap peningkatan hasil belajar Matematika siswa kelas X MIA di SMA Negeri 1 Batang Kuis. Model Discovery Learning memungkinkan siswa secara mandiri mengeksplorasi konsep dan menyelesaikan masalah. Penelitian ini menggunakan metode quasi-eksperimen dengan dua kelompok: kelas eksperimen yang menggunakan model Discovery Learning dan kelas kontrol yang menggunakan metode konvensional. Berdasarkan hasil pretest dan posttest, ditemukan bahwa kedua kelas memiliki distribusi data normal dan varian homogen. Namun, hasil uji ANOVA menunjukkan adanya perbedaan rata-rata skor pretest, sementara posttest tidak menunjukkan perbedaan signifikan antara kedua kelas. Dengan demikian, model Discovery Learning tidak memberikan pengaruh signifikan terhadap hasil belajar Matematika siswa. Faktor-faktor seperti durasi implementasi, kesiapan siswa, serta keterampilan guru dalam menggunakan metode ini kemungkinan berpengaruh terhadap hasil penelitian.

Abstract

Tea is one of the most popular beverages in the world. Produced from Camellia sinensis leaves, tea has been studied to provide health benefits due to the content of important metabolites. This study aimed to investigate the catechin contents, antioxidant, and antibacterial activities of Indonesian tea varieties, namely green tea, black tea, and white tea. Tea infusion was prepared by extracting 1 g of each sample into 10 mL of distilled water and incubated at 80 °C for 60 min. The catechin and epigallocatechin gallate (EGCG) contents of tea extracts were determined using high-performance liquid chromatography (HPLC). Antioxidant activity was measured using the free radical method with 2,2-diphenyl-1-pycrylhidrazyl (DPPH), while antimicrobial activity was assesed using paper disc diffusion assay. The results indicated that green tea had the highest contents of catechin (646 ± 17.14 mg/L) and EGCG (997.8 ± 36.72 mg/L), and antioxidant activity with IC50 of 5.65 µg/mL. Furthermore, green tea and white tea extracts showed inhibitory activity against Gram-positive bacteria such as Micrococcus luteus, Bacillus subtilis, and Staphylococcus aureus whereas black tea had no activity against all bacterial strains tested. Generally, we concluded that white tea and green tea contributed to the higher content of catechins and exhibited strong antioxidant and antibacterial properties.

Abstract

The current interest in exploring white-rot fungi has been concentrated in increasing their ligninolityc enzyme production such as laccase and manganese peroxidase (MnP) due to the great value in industrial application. The presence of appropiate inducers can enhance the enzyme production. Hence, the aim of the study was to investigate the activity of laccase and MnP in response to various aromatic compounds. The fungus Trametes hirsuta was cultured in Glucose Yeast Peptone (GYP) broth (pH 5.0) with the addition of 0.5% of sorghum biomass as substrate. The cultures were then incubated on rotary shaker at 150 rpm at 27oC. The 7-day-old cultures were then supplemented with different aromatic compounds, namely caffeic acid, gallic acid, syringic acid, trans-cinnamic acid, vanillin, and veratryl alcohol. Our results demonstrated that veratryl alcohol, gallic acid and vanillin gave an inductive effect on the value of laccase and MnP activities, with vanillin showing the highest induction. On the contrary, the level of laccase and MnP activities remained low in the presence of aromatic compound such as syringic acid, trans-cinnamic acid and caffeic acid. To conclude, our study reveals that aromatic compounds can be potential as inducers and may contribute to the improvement of laccase and MnP productivity by T. hirsuta.
