Authors: Rusyati Lilit , Rustaman Nuryani Y. , Widodo Ari , Ha Minsu
Published: March 2024

Affective dimension is one that must be assessed. Unfortunately, there is no learning that teaches students specifically how to recognize and control affective. Therefore, this study provides training to students on meta-affective strategies during science learning. The Static-group pretest-posttest design was chosen as the research method because it compares integrated training (facilitated by the teacher) and separate training (independent by students). MATS (Meta-Affective Trait Scale) questionnaire was adapted by adding 34 statements so that the total number is 51 statements. There were two experimental groups, each consisting of 50 students. Statistical tests show that there is no difference in students' meta-affective in integrated training and separate training. However, analysis per statement showed that separate training were better at recognizing and regulating meta-affective. In addition, in both integrated training and separate training, it is equally difficult to reduce negative emotions. This result implies that science learning should also focus on the affective and teacher should not give negative labels to students.

HOW DO E-WORKSHEET USING WIZER.ME BASED GOOGLE SITE IMPROVE HIGHER ORDER THINKING SKILLS AND COMMUNICATION SKILLS?
Authors: Makiyah Yanti Sofi
Published: March 2024

Higher Order Thinking Skills (HOTS) and Communication Skills (CS) must be taught to pre-service physics teacher in the twenty-first century if they are to become future professional physics teacher. Based on the results of the preliminary study it is known that the HOTS and CV categories of physics education students are still lacking with an average score of 25 and 3. In addition, learning time in class is limited to solving problems so lecturers want to take advantage of technology in making teaching materials that facilitate independent practice outside the classroom, easily accessible to pre-service physics teacher (paperless), easy to provide feedback and correction results from worksheets so that learning evaluation is more effective and efficient. One treatment that can be applied to train HOTS and CS is to use teaching materials in the form of electronic-worksheets (e-worksheets) using Wizer.me based Google Site. E-worksheets will be more optimal if applied in learning, namely the Contextual Teaching and Learning (CTL) model and the Blended Problem-Based Learning (B-PBL) model. The purpose of this study was to determine the effectiveness of e-worksheets in CTL and B-PBL using Wizer.me based Google Site, changes to HOTS and CS and to determine student perceptions of using e-worksheets. The research method is quasi-experimental with a two-treatment counterbalanced design. The population of this study was all statistical physics classes for the 2022/2023 academic year, consisting of 2 classes with a total of 66 students. The sampling technique was purposive sampling, with 33 students in each class. Data collection techniques used the HOTS test, communication skills observation sheets and perception questionnaires about the use of CTL and B-PBL-based e-worksheets. The HOTS test is in the form of a description with a total of 3 questions including analyzing (C4), evaluating (C5) and creating (C4). Communication skills observation sheets include systematics/format, use of language, completeness and sequence of contents. The perception questionnaire consists of 9 questions using the Guttman scale. Based on the results of data analysis, it is known that CTL and B-PBL-based e-worksheets are effective in training HOTS and CS with large categories, namely 0.88 and 0.91. The increase in HOTS and CS was in the high category in both classes but the increase in the BPBL-CTL class was better with N-Gain, namely 0.87 and 0.92. The results of the questionnaire analysis stated that physics education students gave a good response with almost all students stating that the use of e-worksheets using Wizer.me based Google Site could increase HOTS and CS and physics education students were more independent in finding solutions to problems. Based on the results of data analysis, it can be concluded that e-worksheets in CTL and B-PBL using Wizer.me based Google Site can increase HOTS and CS.

A Kaleidoscope of Multisensory Perceptions in the Films of Buddhadeb Dasgupta
Authors: Chatterjee Monali
Published: March 2024

In the present age, digital media, particularly films have earned the reputation of successfully forging an alternative reality by offering a multisensory experience to the spectators. Playing a pivotal role in the foundation of Indian realistic cinema, the films of Buddhadeb Dasgupta have conveyed serious, hard-hitting messages through their sensory appeal. His films have been widely applauded and recognized for portraying multisensory poetry on celluloid. His iconic films like Tahader Katha (1992), Grihajuddha (1982), and Bagh Bahadur (1989) reveal the bleakest secrets of the human mind. On the other hand, films like Charachar (1993), Tope and Uro Jahaj convey a unique sense of ethereal existence through their multisensory experience. This paper attempts to analyse the multisensory film aesthetics in some selected films of Buddhadeb Dasgupta that question the cultural codes and set exemplary models of individual, social as well as environmental responsibility through its unique portrayal of multisensory experiences. This experiential perception of these films creates an alternative reality with the help of the stylistic aspects of narration. This paper also attempts to find out what purpose is served by this multisensory appeal and how it has opened new avenues and genres in the discipline of film-making.
Scandinavian Approach to Multisensory Design
Authors: Wiśnicka Anna
Published: March 2024

The text aims to investigate methods and techniques introduced by Scandinavian designers which are beneficial to the overall sensorial aspect of their work. To emphasize the wide spectrum of the subject, various materials would be taken into consideration—wood, glass, metal, textiles. Thanks to the analysis of selected case studies it is possible to showcase the main ideas of how the multisensorial design practices have been implemented within the realm of Scandinavian design, focusing on diversity of examples. The methodology applied uses the analysis method of design history combined with the perspective provided by cultural studies and their analysis of the broad context. To enrich the latter, also certain cultural associations will be considered. Wood provides the visual, tactile, and olfactory experience which has been used in both conceptual and commercial projects. Glass, often considered by designers exclusively for its visual aspects, brings the tactile element of shape and structure, which are meant to mimic the contact with nature, vital for many Nordic projects. Metal and textiles can be considered as opposite sensorial features based on contrasting properties, hot–cold, soft–hard. The study serves as an introductory paper to touch upon the question of multisensory in Scandinavian design, not thoroughly investigated in international literature, by presenting further opportunities for in-depth studies.
Determination of change in the land use and land cover of the Samsun Bafra Delta Plain from 1990 to 2020 using GIS and Remote Sensing Techniques

Land use and land cover changes can have detrimental effects on the ecology, if they are not properly aligned with the characteristics of the land. This study aims to evaluate the temporal changes in land use and land cover of Bafra Delta plain, situated in the east of Samsun province. The region is one of the most significant plains within the Black Sea area. Remote sensing technique was utilized in this research which made use of Landsat images from 1990, 2000, 2010, and 2020. Supervised classification was applied in ENVI 5.3v software to perform calculations, resulting in six main classes. Field work was applied to classify the unclassified classes. The resulting six land use-land cover classes were agriculture lands, forest, dune, marshy, water surface, and artificial areas. To determine land use efficiency, analogue data was digitised and transferred to a GIS database. The agricultural areas occupy the largest portion of the plain, followed by hazelnut and artificial areas. The changes over the last decade, notably the growth of artificial areas and water surfaces, and the reduction of arable lands, highlight significant variations in size across the areas. Furthermore, the study indicated that remote sensing and geographic information system techniques play a crucial role in identifying and monitoring land cover and land use trends on a large-scale to produce accurate and timely data. Poorly adapted land use changes can cause major ecological damage. The aim of this study is to identify the changes over time in land use and land cover of Bafra Delta plain, located to the east of Samsun city and one of the most significant plains in the Black Sea region, using remote sensing techniques. To this end, Landsat images from 1990, 2000, 2010 and 2020 are utilized. To perform the calculations, ENVI 5.3v software was employed, applying a supervised classification technique that resulted in forming six main classes. Fieldwork was conducted to classify the unclassified classes. The resulting land-use and land-cover classes were agricultural land, forest, dunes, marshland, water surface, and artificial areas. To evaluate land-use efficiency, analogue data were digitalised and imported into a GIS database. The plain's most extensive land-use areas consist of agricultural lands, followed by hazelnut and artificial areas. In the last decade, the rise in artificial and water surfaces and the decline in agricultural areas highlights significant changes in the region's size. This study also emphasises the crucial role of remote sensing and geographic information system techniques in generating fast and consistent data for monitoring large-scale land cover and land use trends.

The main regularities of pollutant distribution through the soil profile were established based on the analysis of the content of 15 priority PAHs in 29 soil sections of different soil types located in the coastal zone of the Lower Don and Taganrog Bay with different anthropogenic loads. It was shown that the total content of PAHs in the 0-20 cm layer of soils of coastal territories varies from 172 µg kg-1 to 16006 µg kg-1. In addition, according to the total pollution indicator, (Zc) determines the level of soil pollution, which varies from "not polluted" to "extremely polluted". The influence of pollution sources falls on the 0-20 cm layer of soils of different types and is especially pronounced for subordinate landscapes. With increasing sampling depth, the total PAH content decreases with the redistribution of individual compounds of the PAH group towards the dominance of low molecular weight and 4-ring compounds in the composition of the sum of 15 PAHs and depends largely on the content of organic matter and soil pH. Based on the cluster analysis results, the main factor determining the profile distribution of PAHs is the type of pollutant origin source and its intensity.
