Abstract

In general, e-learning can be defined as learning that utilize or apply the information and communication technology. E-learning is learning activities that use the internet which can be combined with face to face activities in educational institutions. This research was conducted by finding secondary data that the study of literature consisting of journals scientific work and research, books, and online articles on the internet. Implementation of e-learning using the Technology Acceptance Model (TAM), which describes the results obtained are significant factors affecting user acceptance (learners). Users (students or teachers) who already understand the ease of use of the e-learning system and the benefits of using it, it will have the intention and willingness to use e-learning system. The existence of an understanding of the benefits of using strongly influenced by factors outside the organization that electronic teaching materials owned by the e-learning system. Models form the acceptance of a new information technology, the e-learning system that is applied to the sample users, namely euros (relevance of e-resource to the learning needs and accessibility of e-resources in use) and ID (visibility of usage, personal development of computer technology, experience on the use of computers, and knowledge of teaching materials) as a latent factor outside or external factor. PEOU (easiness to learn / understand, easy to use, and frequency of use in teaching), PU (ease to improve learning skills, enhance the effectiveness of learning, address the needs of learning, increase learning achievement, improve the efficiency of learning, and enable the development of ways of learning ), ITU (additional software/plugin support, motivation to continue to use in learning, and motivate other users) and ASU (long usage in learning and satisfaction in the use of learning) as an inside factor or the internal factor.

Abstract

Food Chemistry is one of the elective courses in Chemistry Education Program of University of Palangka Raya. Development of food chemistry materials based on web as an effort to utilize the available computer and internet facilities. One of the advantages of teaching materials based on web is to make it easy for students to access the learning materials after classroom learning. Utilization of computer technology and internet as media development of web-based teaching materials in Chemistry Education Program of University of Palangka Raya is expected to improve the quality of learning. For lecturers and students can provide easiness in the archiving of teaching materials, easy access to open the archives of teaching materials, the ease of doing improvements in teaching materials and ease in the updating of teaching materials. The method of developing food chemistry materials based on web used is the Educational Research and Development method, which is abbreviated as R & D. Gall et al. (2003) states R & D is a process used to develop and validate educational products. This development uses research methods and development of 3D models, namely Define, Design, and Develop, modification 4D Thiagarajan model. In the study conducted a limited-scale trial. Food chemistry materials based on web in the form of learning websites with the address www.kimiakesehatan.blogspot.co.id worthy to be used as a medium of teaching materials in Chemical Education Study Program of University of Palangka Raya.

Abstract

Sintesis, karakterisasi dan uji adsorpsi komposit magnetik lempung putih asal Kalimantan Tengah terhadap warna zat warna pada limbah cair telah dilakukan. Sintesis komposit magnetik lempung putih dilakukan dengan metode kopresipitasi. Karakterisasi komposit magnetik lempung putih dilakukan dengan spektroskopi FTIR (Fourier Transform Infrared), XRD (X-ray diffraction) dan VSM (Vibrating sample magnetometer). Uji adsorpsi dilakukan menggunakan sistem batch dengan kajian adsorpsi yang dipelajari meliputi pH optimum, kinetika adsorpsi dan kesetimbangan adsorpsi. Hasil penelitian menunjukkan bahwa metode kopresipitasi telah berhasil mengkompositkan oksida besi fasa magnetit pada lempung putih asal Kalimantan Tengah dengan nilai magnetisasi sebesar 21,38 emu/g. Lempung putih, lempung putih teraktivasi dan komposit magnetik lempung putih mampu mengadsorpsi Zat warna pada limbah cair dari dalam larutan dengan adsorpsi maksimal secara berturut-turut terjadi pada pH 3, 3 dan 2. Kajian kinetika dan kesetimbangan adsorpsi menunjukkan bahwa adsorpsi Zat warna pada limbah cair oleh ketiga jenis adsorben mengikuti kinetika orde dua semu dengan pola isoterm Langmuir. Komposit magnetik lempung putih asal Kalimantan Tengah mampu meningkatkan kapasitas adsorpsi Zat warna pada limbah cair sampai dengan 2 kali lipatnya dan dapat mempercepat proses pemisahan partikel adsorben dari dalam larutan menggunakan medan magnet eksternal.

Abstract

Sintesis ferrat sebagai pendegradasi methylene blue telah dilakukan. Sintesis dilakukan dengan mereaksikan larutan Fe(NO3)3 dan NaOCl sebagai oksidator pada kondisi alkalis. Reaksi yang terjadi antara ferrrat dan methylene blue dimonitor menggunakan spektrofotometer UV-Vis. Pengaruh beberapa parameter seperti pH dan rasio molar dari ferrat dan methylen blue juga dipelajari pada penelitian ini. Hasil penelitian menunjukkan bahwa ferrat dapat mendegradasi methylen blue secara efektif pada pH 9,6, dengan persentase degrdasi terbesar terdapat pada rasio molar ferrat dan methylene blue 3 : 1 yaitu 87,8%. Hal ini menunjukan bahwa ferrat merupakan bahan alternatif dan ramah lingkungan yang dapat digunakan untuk mendegradasi zat pewarna azo.Kata Kunci: Ferrat, methylene blue

Abstract

This study aims to measure the problem-solving ability of Physics Education students on the topic of chemical bonding and molecular shape in the Basic Chemistry course. The measurement was conducted in December 2024 using 20 essay-type questions developed based on Polya’s problem-solving indicators: understanding the problem, devising a plan, carrying out the strategy, and evaluating the result. The research subjects consisted of 12 students enrolled in the Basic Chemistry course. Data were analyzed quantitatively using descriptive statistics by calculating the percentage of achievement for each indicator. The results showed that the students’ problem-solving abilities varied across the indicators. The average achievement scores were 75.40% for understanding the problem (good category), 69.20% for devising a plan (fairly good category), 67.50% for carrying out the strategy (fairly good category), and 59.60% for evaluating the result (poor category). These findings indicate that students were relatively capable of understanding problems and planning solutions, but they still faced difficulties in consistently implementing strategies and were particularly weak in evaluating their results. In conclusion, the problem-solving ability of Physics Education students on the topic of chemical bonding and molecular shape was generally in the fairly good category, with the main weakness found in the evaluation stage. This study recommends the implementation of learning strategies that emphasize reflection and answer verification, such as problem-based or inquiry-based learning models, to enhance students’ problem-solving skills more comprehensively.
