Abstract

Penelitian ini merupakan penelitian deskriptif kuantitatif dengan tujuan mendeskripsikan bagaimana respon positif konsenttrasi belajar siswa terhadap pembelajaran kurikulum merdeka di daerah 3T. Populasi dalam penelitian ini adalah siswa/i sekolah menengah atas daerah di 3T Indonesia dan sampel sebanyak 72 orang siswa dengan teknik random sampling. Instrumen yang digunakan dalam penelitian ini adalah kuisioner dengan pernyataan 24 item yang tersebar ke dalam 3 dimensi, angket yang disusun mengikuti skala likert. Respon positif untuk dimensi peningkatan konsentrasi belajar (40,34%), dimensi kolaborasi (34,79%) dan dimensi minat belajar (33,65%). Namun demikian, ada respon negatif implementasi kurikulum merdeka pada dimensi konsentrasi belajar (6,39%), kolaborasi (5,79%) dan dimensi minat belajar (5,52%). Secara umum, peserta didik SMA daerah 3T merespon positif implementasi kurikulum merdeka dengan mempertimbangkan pelatihan kurikulum merdeka secara menyeluruh di daerah 3T, namun masih ada siswa memberi respon negatif. Hal ini harus disikapi oleh pemerintah dalam upaya peningkatan efektivitas kurikulum merdeka.

Abstract

This study aims to determine students' perceptions of the effectiveness of online chemistry learning during the Covid-19 pandemic. The study population was all students of the Chemistry Education Study Program, Faculty of Teacher Training and Education, Indonesian Christian University. The research sample was 47 students of the Chemistry Education Study Program at Indonesian Christian University, selected using the saturated sampling technique. The instrument used was a closed questionnaire about the perceptions of Chemistry Education students towards online learning which was compiled using the Likert scale method, consisting of three indicators, namely, acceptance, understanding, and evaluation. The research data were analyzed using descriptive statistics. The results of the study showed that students' perceptions of online chemistry learning during the Covid-19 pandemic for the acceptance indicator were 75.38% in the good category, the understanding indicator was 72.19% in the good category, and the evaluation indicator was 70.26% in the good category. When generalized, students' perceptions of online chemistry learning averaged 72.61% in the good category. Thus, the implementation of online learning during the Covid 19 pandemic went well and students thought that the facilities provided could support learning well.

Abstract

In the era of technology that continues to develop rapidly, students' needs for technology-based chemistry learning media are increasingly urgent. However, it cannot be denied that local wisdom also plays an important role in education. This research aims to analyze the needs of SMA MIPA students in Sitaro Regency for chemistry learning media based on technology and local wisdom. The research method used is quantitative descriptive. The results of data analysis show that the average score for all statement items is 3.99 on a Likert scale (maximum score 5), meaning that students generally agree with the use of learning media based on local wisdom. Further analysis shows that there is a significant difference (sig 0.05) in the perceptions of female and male students. Female students have a higher perception regarding the importance of using learning media based on local wisdom in learning chemistry. Likewise, students in classes X, XI, and XII showed differences in student perceptions (sig 0.05). Class XII students (4.01) have a higher perception than class XI students (3.98) and class X (3.97). Based on this research, it was concluded that SMA MIPA students in Sitaro Regency need chemistry learning media based on local wisdom.

Abstract

This community service aims to provide support and training to PKK women on Tidung Island. Service implementation is carried out using presentations, interactive discussions, and direct practice to improve the village's capacity and creativity. The objectives to be achieved by this activity are to increase knowledge about the effects of careless disposal of used cooking oil waste and to improve skills in handling used cooking oil so that it is a valuable useful treatment. Used cooking oil is waste cooking oil that has been used many times and contains carcinogenic compounds that are difficult to decompose. Both of these properties are dangerous to health and the environment if used cooking oil is consumed and discharged into the environment without change. To achieve this goal, the method that will be used in this activity is to provide health education on the effects of careless disposal of used cooking oil waste and subsequent processing practices using cooking oil into candles. The outcome of undertaking this activity is an increased understanding of the impact of used cooking oil waste on health and the environment. In addition, you can also take advantage of used cooking oil scraps to make candles.

Abstract

The development of technology-based learning platforms and media has been widely carried out; however, most of efforts primarily focus on increasing student interest, while less attention is given to enhancing skills and scientific thinking processes. The purpose of this research was to develop a technology – based learning media, namely a Virtual Reality (VR) laboratory integrated with Artificial Intelligence (AI) to support students’ scientific thinking skills and processes. The AI - integrated VR laboratory was specifically  developed for the implementation of acid-base titration practicums. The research followed the ADDIE development model. During the implementation phase, the product was tested on 31 students from Chemistry Education Study Program at UKI, selected using a random sampling technique. Data collection, particularly for product evaluation, was conducted using a non-test instrument in the form of a Likert scale questionnaire. The instrument consisted of indicators of usefulness, efficiency, and interest which were share via Google Form link. Before being distributed to student, the instrument has been validated by an expert validator with a background in chemistry learning media. The results of the analysis indicated that the AI-integrated VR laboratory received positive response from students with a percentage level of 80.79% for the usefulness indicator, 77.06% for the efficiency indicator, and 79,45% for the interest indicator. Therefore, the result of the development of VR laboratory integrated with AI can be considered as a viable alternative learning media for conducting acid-base titration practicum.
