Abstract

Air gambut merupakan salah satu air permukaan dan dimanfaatkan oleh masyarakat yang bermukim didaerah rawa gambut dengan karakteristik kandungan bahan organik yang tinggi, kandungan besi yang tinggi serta memiliki pH yang rendah dengan warna yang pekat. Penelitian ini bertujuan untuk menganalisis kemampuan daya serap arang aktif cangkang sawit terhadap ion Besi (Fe), Mangan (Mn) dan zat warna pada air gambut. Penelitian ini merupakan penelitian eksperimental dengan menggunakan Rancangan Acak Lengkap (RAL) non faktorial karena hanya menggunakan satu faktor perlakuan yaitu massa arang aktif yang berbeda yaitu 10 g, 15 g dan 20 g sebanyak 3 (tiga) kali pengulangan. Penelitian ini memiliki 2 (dua) parameter yaitu (1) Parameter fisika yang terdiri dari bau, warna, suhu dan zat padat terlarut (TDS) dan (2) Parameter kimia yang terdiri dari pH, Besi (Fe) dan Mangan (Mn). Hasil penelitian menunjukkan bahwa rata-rata daya serap arang aktif dengan aktivator NaOH yang memiliki daya serap tertinggi pada setiap perlakuan yaitu dengan massa 20 g untuk Fe (1,49 mg/l) dan Mn (0,059 mg/l). Rata- rata daya serap arang aktif dengan aktivator HCl yang memiliki daya serap tertinggi yaitu dengan massa 10 g untuk Fe (0,82 mg/l) dan Mn (0,051 mg/l). Penyerapan terbaik Fe dan Mn pada air gambut dengan menggunakan arang aktif teraktivasi NaOH yaitu pada massa 20 g. Penyerapan terbaik Fe dan Mn pada air gambut dengan menggunakan arang aktif teraktivasi HCl yaitu pada massa 10 g. Arang aktif cangkang sawit yang diaktivasi menggunakan aktivator HCl dapat menyerap warna pada air gambut.

Abstract

The implementation of the discovery learning model is that students are able to construct their own knowledge that they must master through 6 (six) stages of learning discovery, namely: (i) stimulation; (ii) problem statements; (iii) data collection;(iv) data processing; (v) verification; (vi) generalization. In its application, students need a study guide to be able to carry out discovery learning activities independently to obtain new knowledge, this research aims to produce a Student Worksheet (LKS) as a learning guide in learning salt hydrolysis with a discovery learning model in class XI high school students. The development of LKS was carried out by adapting the 4-D development model (define, design, d evelop, disseminate) from Thiagarajan. The resulting LKS products are assessed for feasibility using professional judgement by involving chemists, pedagogists, and learning media experts. The revised LKS product based on expert input is then tested for readability by potential users. Furthermore, LKS is implemented on a limited basis in chemistry learning in schools to determine its effectiveness in guiding discovery learning activities and improving students' understanding of the concept of salt hydrolysis. The limited implementation trial was carried out using a pre-experimental design of the One-Shot Case Study model involving 69 high school students in Palangka Raya city. The results showed that the LKS developed was suitable for use with a feasibility value of 92.45%. The effectiveness of LKS in guiding students to carry out discovery learning activities is in the very good category with an average of 97.75% and LKS is effective in improving students' mastery of the concept of salt hydrolysis by obtaining an average N-Gain score of 0.89.

Abstract

This study aims to describe the concept mastery of students in class XI MIPA 3 of SMA Negeri 3 Palangka Raya through discovery learning assisted by inductive student worksheets (LKS-Induktif). The subjects of this study were students of class XI MIPA 3 who had not yet received the sub-topic on acidity level (pH). The instruments used in this research included a concept mastery test (pretest and posttest) in the form of 5 essay questions, a learning management observation sheet, and a student response questionnaire. The data obtained were analyzed descriptively. The results of the data analysis showed: a) The average concept mastery on the indicator of explaining the definitions of strong acid, weak acid, strong base, and weak base increased by 33.8%, b) The average concept mastery on the indicator of calculating the pH of strong acid solutions based on concentration data increased by 52.3%, c) The average concept mastery on the indicator of calculating the pH of strong base solutions based on concentration data increased by 48.5%, d) The average concept mastery on the indicator of analyzing the pH of weak acids based on concentration data and acid dissociation constant (Ka) increased by 63.5%, e) The average concept mastery on the indicator of analyzing the pH differences of weak base solutions based on concentration data and base dissociation constant (Kb) increased by 83.8%.

Abstract

Global demands for more responsible and sustainable mining practices make understanding environmentally friendly gold mining operations increasingly crucial. This context is particularly relevant in Gunung Mas Regency, Central Kalimantan, where small-scale gold mining practices have triggered socio-economic dilemmas between financial gains for the community and serious risks to the environment (mercury pollution) and health. This issue highlights the need for educational interventions that can bridge the concepts of chemistry with real socio-scientific issues (SSI). This study aims to develop a feasible, practical, and effective SSI-based Student Worksheet for Green Chemistry topic. The research method used was Research and Development (R&D) with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The SSI-based Student Worksheet was developed to encourage active learning, critical thinking, and student team collaboration in investigating and solving mining problems. A purposive sampling technique was applied to select one out of six tenth grade science classes at MA N 1 Sepang. The selected class, consisting of 20 Tenth-Grade Science students, was involved in the evaluation process, assessing the effectiveness of the product after its implementation in the class. The findings demonstrated that the developed SSI-based worksheet was highly feasible (teacher assessment average of 3,60) and highly practical for classroom use (student response rate of 87,68%). Furthermore, descriptive analysis revealed a positive shift in students' affective domain, characterized by the complete elimination of the 'Not enough' environmental attitude category and an increase in the proportion of students reaching 'Good' categories. In conclusion, while the SSI-based student worksheet was proven to be highly feasible and highly practical tool for enhancing students’ attitude toward environment, its effect on students' long-term environmental attitudes remains relatively limited. This suggests that short-term interventions are insufficient to permanently change deep-rooted perspectives, and further comprehensive, long-term educational strategies are required.

Abstract

This study aims to explore and develop local culture into teaching materials. The production of Baram and betel lime can be used as examples to study thermochemical concepts, thereby producing interactive teaching materials based on Dayak (Central Kalimantan) ethnochemistry in thermochemistry. This research is a Research and Development (R&D) study using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). This research was conducted at SMA Negeri 1 Palangka Raya with 80 grade XI phase F students as research subjects. Data were collected through validity questionnaires, pretest and posttest questions, and teachers response questionnaires. Interactive teaching materials based on Dayak (Central Kalimantan) ethnochemistry in thermochemistry can enrich the study of local culture utilization, especially in chemistry learning in thermochemistry, and become an alternative teaching material and learning resource variation during the chemistry learning process. The percentage of teaching material trial results, the percentage of feasibility from subject matter experts was 83.33% and pedagogical experts was 96.88%, readability test was 81.7%, effectiveness with an N-gain value of 0.76 and a Mann-Whitney test sig value of 0.01, and positive responses from chemistry teachers was 88.6%. The trial results show that interactive teaching materials based on Dayak (Central Kalimantan) ethnochemistry on thermochemistry are feasible, easy to understand, and effective to improve student learning outcomes.
