Abstract

OPEFB is one source of natural fiber-based composites which have the potential to become activated carbon and nanocellulose. This study aims to synthesize and characterize the activated carbon/alginate/nanocellulose-Cu composite. The characterization used in this study is FTIR and PSA. The synthesis of activated carbon/alginate/nanocellulose-Cu composites began with a process of carbonization and activation with H3PO4 to produce Activated Carbon. Followed by a bleaching process with NaClO2 and a delignification process with Na2SO3 and NaOH to produce Nanocellulose. Alginate using commercial alginate. Furthermore, the three ingredients were mixed until homogeneous and put into a 0.1M CuSO4 solution to produce beads. The results of the characterization of characterization of PSA Nanocellulose obtained a particle size of 41.05 nm and the result of FTIR characterization on the activated carbon/alginate/nanocellulose-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, and β- glucosidic bonds between glucose units which indicate nanocellulose.

Abstract

Research on the slow release kinetics of Fe(III) ions from Activated Carbon/Alginate-Fe(III) composites or abbreviated as K/A-Fe(III) has been carried out. The aim of this research was to synthesize K/A-Fe(III) composite as a material that has the potential to become a slow release micronutrient fertilizer and to study the kinetics of slow release of Fe(III) ions from the composite. The K/A-Fe(III) composite was synthesized by mixing alginate suspension and activated carbon (alginate: activated carbon weight ratio = 1:3 and 3:1) until homogeneous. Composite grains were characterized using Fourier Transformed Infrared (FTIR) spectroscopy, the kinetics of Fe(III) release from the three composite variations found that KAlg31 composite showed more absorption and release of Fe ions than KAlg13.

Abstract

This research aims to develop an interactive media Virtual Laboratory on the topic of chemical equilibrium. This research was conducted at SMA Negeri 1 Galang. This type of research uses the development method (R&D) with the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation, but this research is limited to the development stage. This research uses a sample of 28 students in 1 class, 1 chemistry teacher, and 2 expert validators. Data collection in this study was conducted through interviews and questionnaires. The validation results by media experts indicate that this virtual laboratory is valid with an average feasibility percentage of 84.71%, while validation by content experts obtained a percentage of 90%. Teacher responses indicate validity with an average of 95.55%, and student responses provide an average of 96.45%, all of which fall into the "very feasible" category.Keywords: : Virtual Laboratory, Chemical Equilibrium, Articulate Storyline 3, Development, Interactive MediaDOI: 10.23960/jppk.v13.i3.32285

Abstract

The development of technology in the world of education is a demand for the curriculum, so currently technology is developing, namely Augmented Reality, which allows its use to interact in a real way with the system. The application of Augmented Reality can be a solution to educational problems that require the application of science and technology in every subject, especially chemistry in chemical equilibrium material. Augmented Reality-based LKPD was developed based on validation results, teacher and student responses. The development method used is the research and development (R&D) method with the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) development model. The data collection techniques used were teacher interviews, analysis of student needs, media and material validation sheets and student response questionnaires. Based on validation carried out on interactive LKPD based on Augmented Reality on chemical equilibrium material, the level of validation by media expert validators was 95% with the criteria "very feasible". And a response test was carried out on students, obtaining a percentage of 76% with the "interesting" criteria. So it can be concluded that overall the interactive LKPD product based on augmented reality media on chemical equilibrium material that has been developed is interesting for students to study for use in the learning process, especially on chemical equilibrium material.Keywords: LKPD, Augmented Reality, Chemical EquilibriumDOI: 10.23960/jppk.v13i3.32181

Abstract

Education inequality in Indonesia remains a complex challenge, especially in remote areas and low-income communities. This study uses the Systematic Literature Review (SLR) method to identify the main factors causing education inequality, such as limited infrastructure, shortage of qualified teaching staff, socio-economic barriers and government policy implementation constraints. The findings reveal that inadequate infrastructure and a shortage of qualified teachers are prevalent in rural and underdeveloped regions, significantly limiting educational quality. Geographical disparities and socio-economic challenges further exacerbate these inequalities, creating systemic barriers to equitable access. While programs such as the Indonesia Smart Program (PIP) and School Operational Assistance (BOS) have provided partial relief, their effectiveness is often hampered by unequal resource distribution and bureaucratic inefficiencies. This study recommends a data-driven approach for more effective resource allocation, cross-sector collaboration and strengthening of education policies to create an inclusive and sustainable education system. The findings provide important insights for policymakers to overcome structural barriers and ensure equitable education for all Indonesian children.

Abstract

Active learning should involve students directly in the learning process through interaction with peers and teachers. However, classroom instruction often fails to engage students effectively, with limited use of varied instructional media and models. This study aims to develop a Respiratory Card learning medium using the Project-Based Learning (PjBL) model to improve learning outcomes of fifth-grade elementary school students on the topic of the human respiratory system. This research employed a Research and Development (R&D) approach using the 4D development model, which includes the stages of Define, Design, Develop, and Disseminate. Data collection techniques included interviews, observations, questionnaires, and tests, while data were analyzed qualitatively and quantitatively. The results showed that: (1) the Respiratory Card learning media was declared valid with average scores of 88% from content experts and 90.6% from media experts, categorized as “highly feasible” using a Likert scale; (2) the media was considered practical based on a 92% average score from teacher responses, categorized as “very practical”; and (3) the media was effective, as indicated by an improvement in students’ test scores to an average of 84.2% at SDS Attaufiq Medan, and significant differences were found in learning outcomes between the experimental and control classes at UPT SDN Percobaan (sig. value = 0.000 < 0.05). The use of the Respiratory Card media enhanced student engagement and improved learning outcomes.

Abstract

Di Indonesia, teknologi sangat penting untuk kesetaraan pendidikan, terutama di daerah pedesaan yang memiliki akses terbatas. Artikel ini mengkaji bagaimana kemajuan teknologi dapat meningkatkan akses pendidikan dan menutup kesenjangan antara daerah perkotaan dan pedesaan. Penelitian ini mengkaji penggunaan teknologi termasuk e-learning dan aplikasi pembelajaran mobile dengan menggunakan metode deskriptif kualitatif berdasarkan tinjauan literatur. Menurut penelitian ini, yang didasarkan pada studi literatur terhadap 15 jurnal nasional yang diakui, teknologi meningkatkan efektivitas pembelajaran, mempermudah pembelajaran jarak jauh, dan mendorong strategi pengajaran yang kreatif. Tujuan dari penelitian ini adalah untuk melihat bagaimana teknologi dapat membantu mengatasi kesenjangan pendidikan di Indonesia, terutama yang terjadi antara daerah perkotaan dan pedesaan. Namun, hasil penelitian ini juga menunjukkan beberapa masalah penting, termasuk pelatihan yang tidak memadai untuk guru, kesenjangan dalam literasi teknologi, dan kurangnya infrastruktur digital. Kerja sama lintas sektor untuk menciptakan sistem pendidikan digital inklusif yang mendukung Indonesia Emas 2045 adalah salah satu solusi yang disarankan.
