Abstract

Berpikir kritis ialah salah satu kemampuan yang wajib dimiliki siswa dalam menghadapi tantangan abad ke-21. Kemampuan ini membantu siswa untuk berpikir secara logis, serta mampu mengevaluasi berbagai informasi yang mereka terima, khususnya di era digital. Tujuan penelitian ini adalah untuk menemukan perbedaan antara model Process Oriented Guided Inquiry Learning (POGIL) dan model Discovery Learning pada kemampuan berpikir kritis siswa pada materi aditif dengan metode penelitian kuantitatif. Populasi penelitian yakni semua siswa kelas VIII SMP Negeri 2 Samarinda yang terdiri dari sebelas kelas. Penentuan dilaksanakan dengan teknik cluster random sampling yang tersusun dari dua kelas yakni kelas eksperimen 1 memakai model Discovery learning (DL) dan kelas eksperimen 2 memakai model Process Oriented Guided Inquiry Learning (POGIL). Desain penelitian ini memakai post-test only group design. Instrumen yang digunakan pada penelitian ini adalah instrument tes berupa soal uraian (essay) dengan menggunakan 6 indikator berdasarkan Fisher meliputi mengidentifikasi masalah, menyusun alternatif pemecahan masalah, mengumpulkan infomasi relevan, mengungkapkan pendapat, membuat kesimpulan, mengevaluasi argumen. Data dianalisis dengan memakai uji Independent Sample T-test. Hasil analisis menunjukkan jika siswa pada kelas yang menerapkan Process Oriented Guided Inquiry Learning (POGIL) (69,27) mempunyai rata-rata kemampuan berpikir kritis yang lebih tinggi dibandingkan dengan siswa pada kelas Discovery Learning (59,90). Aktivitas guru dan siswa menunjukkan bahwa tingkat keterlibatan dalam pembelajaran Discovery learning mencapai 93% dan tingkat keterlibatan dalam pembelajaran Process Oriented Guided Inquiry Learning (POGIL) mencapai 97%. Dengan demikian, terdapat perbedaan kemampuan berpikir kritis antara model Process Oriented Guided Inquiry Learning (POGIL) dengan model Discovery Learning (DL).

Abstract

Kedayan root is a medicinal plant that is traditionally used by the community as medicine, especially as an antidote to poison. This research aimed to determine the antioxidant activity of the ethyl acetate soluble fraction of Tabar Kedayan root extract (Aristolochia papillfolia Ding hou). The fractionation method used is solid-liquid extraction using ethyl acetate solvent to obtain a soluble fraction of ethyl acetate, then vacuum liquid chromatography fractionation using the eluent ratio n-hexane: ethyl acetate and obtain fraction A, fraction B, fraction C, fraction D, fraction E, fraction F. Testing of antioxidant activity using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method spectrophotometrically. The data obtained was analyzed using linear regression to determine IC50. The results of the C fraction test on the ethyl acetate soluble fraction of Tabar Kedayan roots (A. papillfolia) have antioxidant activity with an IC50 value of 139.11 ppm.

Abstract

Indonesia has many extraordinary biological resources, including flora that have great potential to function as a source of vegetable protein, such as Moringa oleifera and Sauropus androgynus. Humans need protein because it is a macromolecule that does many things for life systems, and is needed for tissue replacement and energy supply. Protein functions as a catalyst, transports molecules such as oxygen, supports the immune system, and transmits nerve impulses. The focus of this study was the protein content in moringa leaves (Moringa oleifera) and katuk leaves (Sauropus androgynus) in the shoots, young, and old parts. The moringa leaf samples examined showed a protein content of 22.24% in the shoots, 2.992% in the young leaves, and 4.272% in the old leaves. Meanwhile, fresh katuk leaves showed a protein content of 3.898% for the shoots, 4.767% for the young leaves, and 5.127% for the old leaves. The method used was the Kjeldahl method, namely the process of destruction, distillation, and titration used to measure protein content. The results of the study showed that moringa leaves, especially the shoots, have a higher protein content compared to katuk leaves, indicating that moringa leaves can function as an important source of vegetable protein. This study aims to measure and compare the protein levels in the top, young and old leaves of the two plants in fresh condition, in order to provide a more accurate picture of the nutritional potential of each part of the leaf and its contribution to the diversification of vegetable protein sources.

Abstract

A module is an educational material or learning tool that includes teaching materials, methods, and assessments that are developed in a systematic and structured manner to achieve expected competency goals. The aim of this study is to develop a valid, practical and effective mangrove module based on ethnoscience on biodiversity. The type of research is R&D which refers to the ADDIE method developed by Mayfield. Data collection techniques consist of expert verification, observations, tests, questionnaires, and interviews. The results of the study show that, this module was developed based on the manual previously used by SMA IT Darul Hikmah Bontang students to learn biology. The module validity result for the module is 99%, which is in the very valid category. The material validity result of the module was in the very reasonable category at 84.69%. The linguistic validity result of the module was 73.6% in the valid category. The results of the student survey regarding the practicality of the module were 88.65%, which fell into the very practical category. The effectiveness module in improving student’s critical thinking ability and environmental awareness have n-gain values ​​are 0.55 and 0.44. It can be concluded that the development of the ethnoscience-based mangrove module in the intermediate category has been effectively used to improve the critical thinking skills of the students of SMA IT Darul Hikmah Bontang.
