Abstract

This study aims to determine the adsorption and desorption abilities of activated carbon and Cu-(TAC) composites in the β-carotene adsorption process on Crude Palm Oil (CPO). Oil Palm Empty Fruit Bunches (EFB) are used as activated carbon and modified with MOFs Cu-(TAC). Activated carbon and Cu-(TAC) composites were characterized by XRD, SEM-EDX, and BET. The concentration of β-carotene absorbed during the adsorption process was analyzed using a UV-Vis spectrophotometer. The variations used to determine the optimum conditions for absorption of β-carotene were the mass variation of the adsorbent and the variation in the contact time between the adsorbent and adsorbate. The results of the characterization of activated carbon showed a sharp absorption in the presence of O-H, C-H and C-O groups indicating the presence of cellulose. Activated carbon is amorphous and the Cu-(TAC) composite has a crystal structure and its pore size is mesoporous. The optimum conditions for the use of activated carbon for β-carotene adsorption were the mass variation of 8 grams with 0.495 ppm of β-carotene and contact time at 120 minutes with 2.605 ppm of β-carotene. The optimum condition of the Cu-(TAC) composite in the β-carotene adsorption process was at 4 gram mass variation with 1.026 ppm β-carotene content and optimum contact time at 60 minutes with 6.384 ppm β-carotene content. The ability of desorption can be seen from the percentage of desorption showing activated carbon in the 150th minute with 96.252% while in the Cu-(TAC) composite in the 30th minute with 88.188%.

Abstract

OPEFB is one source of natural fiber-based composites which have the potential to become activated carbon. This study aims to synthesize and characterize the activated carbon/alginate -Cu composite. The characterization used in this study is FTIR. The results of this study The synthesis of activated carbon/alginate -Cu composites began with a process of carbonization and activation with H3PO4 to produce Activated Carbon. Alginate using commercial alginate. Furthermore, the three ingredients were mixed until homogeneous and put into a 0.1M CuSO4 solution to produce beads. The characterization of FTIR characterization on the activated carbon/alginate-Cu composite contained the functional group OH group, triple C bond from stretching alkyne, C=C aromatic group, C-H alkane group, C-O group , the P=O stretching vibration of the P-O-C group and the alcohol OH group expressing the active carbon; there are functional groups of hydroxyl (OH), carboxyl, carbonyl, and C-O-C and –COOH bonds which represent alginate and there are OH functional groups, stretching C-H bonds, C-O stretching, stretching C-C. The KALg Cu13 sample had a peak at a wavelength of 2838.79 Cm-1 Where the four samples show the presence of C≡N groups

Abstract

This study aims to analyze the differences in learning outcomes and student engagement between the Problem Based Learning (PBL) model and the Discovery Learning (DL) model supported by learning videos, as well as to identify the relationship between these factors in the context of redox reactions at MAS Muallimin Univa Medan. The sample consists of two classes randomly selected from the Class X MIA population: the PBL class (X MIA 2) and the DL class (X MIA 3). The research instruments included a multiple-choice test with 20 valid and reliable questions to assess learning outcomes and an observation sheet to evaluate student engagement. Data were analyzed using independent sample t-tests. Results indicated that the PBL class had lower scores in both engagement and learning outcomes compared to the DL class. Statistical analysis revealed significant differences in engagement and learning outcomes (α < 0.05), with a positive correlation between student engagement and learning outcomes. The conclusion of this study is that there are differences in learning outcomes and engagement between the two models, as well as a significant relationship between student activity and learning success, with contribution rates for engagement reaching 64.3% and 24.9%.Keywords: Learning Outcomes, Learning Activities, Problem Based Learning, Discovery Learning, Learning Videos¸ Redox Reactions.DOI: 10.23960/jppk.v13.i3.30701

Abstract

This study aims to determine the effectiveness of using Kahoot media and e-LKPD based on the Discovery Learning model in improving student learning outcomes in acid-base solution material at SMA Negeri 10 Medan. The research method used is a quasi-experimental design with a Pretest-Posttest Non-Equivalent Control Group Design. The subjects of the study consisted of four classes: F1, F2, F3, and F5, with each class consisting of 35 students. Class F1 used Kahoot media, F2 used e-LKPD, F3 used a combination of both, and F5 served as the control class. The instrument used was an objective test in the form of 20 multiple-choice questions. The results showed that the average improvement in student learning outcomes was higher in the experimental classes than in the control class. The Independent z-test revealed a significant difference between the experimental and control classes. Thus, the use of Kahoot media and e-LKPD based on discovery learning has proven effective in improving student learning outcomes in acid-base material.

Abstract

Pembelajaran IPA merupakan salah satu model penerapan kurikulum yang dianjurkan untuk diterapkan mulai pada pendidikan dasar. Materi dari pembelajaran IPA sebaiknya diaktualisasikan melalui peragaan, bentuk percobaan atau demonstrasi yang dilakukan di Laboratorium. Pelaksanaan praktikum IPA dengan KIT praktikum menjadi lebih mudah dan dapat mengurangi risiko kecelakaan laboratorium. Salah satu tugas pendidik adalah mengembangkan potensi siswa namun permasalahan yang dihadapi guru adalah belum bisa berinovasi supaya proses pembelajaran IPA dilaksanakan di Laboratorium saat mendapatkan materi yang semestinya dilakukan dengan metode praktikum. Guru-guru di SMP IT Nurul Fadhilah selama ini melakukan proses peembelajaran hanya sebatas teori di dalam kelas, hal ini dikarenakan keterbatasan akses dan peralatan belum memadai yang menunjang praktikum IPA. Hal ini dirasakan oleh guru saat berinteraksi dengan siswa memberikan contoh penerapan praktikum IPA yang hanya sebatas teori. Pelatihan ini bertujuan untuk membekali guru dan siswa dalam mengembangkan kreativitasnya dalam mengintegrasikan penggunaan KIT IPA pada pembelajaran IPA dan metode praktikum akan membantu mempercepat pemahaman terhadap pembelajaran IPA serta memberikan langkah kongkret dalam pemanfaatan laboratorium sebagai tempat belajar yang menyenangkan.

Abstract

Problem Based Learning (PBL) learning model is a set of learning activities that emphasize the process of solving problems faced scientifically. The use of video media can help students' learning process and will have a big impact on the learning outcomes of thermochemical material because almost everyone, from children to the elderly, now has a smartphone. In addition to learning videos, powerpoint is one of the learning media that can help students who have learning difficulties. The purpose of this study was to investigate whether the thermochemistry learning outcomes taught using PBL-based learning videos were higher than the thermochemistry learning outcomes taught using PBL- based PPT. This study involved the experimental class I and the experimental class II. From the results of the study, the average pre-test for the experimental class I was 41,95 and the experimental class II was 41.44. After being treated with learning in both experimental classes, post-test was then recommended to determine learning outcomes, the post-test average of experimental class I was 83.14 and experimental class II was 78.44. The results showed that the experimental class I which was taught by learning video media and the PBL model was higher than the learning outcomes of the experimental class II which was taught by the powerpoint media and the PBL model. It can be concluded that the use of instructional video media, learning outcomes are higher than the use of powerpoint media.
