The Awareness of Social Studies Pre-Service Teachers About the Concept of Environmental Waste Recycling and Acrostics Trials

Due to globalization and the impact of industrialization and urbanization, natural resources are wasted, and popular consumption leads to environmental waste. The problem of waste that deteriorates individual and social life is a prominent current issue. Recycling, described as the remanufacturing, production and employment of collected material, is an important solution to that problem. The present study aimed to determine the awareness of pre-service social studies teachers about the concept of environmental waste recycling and to analyze acrostic poems written by the participants. The study findings included the views of the pre-service social studies teachers. A semi-structured interview form was developed by the authors under expert supervision and employed to collect the views of the pre-service teachers. The pre-service teachers included in the study sample were assigned with simple random sampling technique and the study group included 162 pre-service social studies teachers. The descriptive survey model was employed in the study, the data were analyzed with content and descriptive analysis techniques to determine thematic codes. Furthermore, an acrostic poem authoring activity on the concept of recycling was conducted with the participants. The poems authored by the participants are presented as a category in a table in the findings section. The study findings revealed significant results on the recycling concept and processes. It was determined that the views of the participating pre-service social studies teachers reflected a high level of awareness on the concept of recycling and exhibited various perspectives on the implementation.

A novel route for the synthesis of pseudopolyrotaxane containing γ-Cyclodextrin based on environmental waste recycling

The disposal of environmentally harmful waste is one of the most important challenges nowadays, especially when it is turned into important products for the industry. In this perspective, pseudopolyrotaxane containing gamma-cyclodextrin was synthesized for the first time from polystyrene waste recycling. Initially, polystyrene sulfonic acid (1) was facilely obtained in good yield by sulphonation of styrofoam (expanded polystyrene, EPS). Thereafter, it was used to synthesis of pseudopolyrotaxane (2). The chemical structure of the newly synthesized polymers (1) and (2) was established by their spectral analysis such as FT-IR, 1H-, 13C-, and cosy-NMR spectroscopy. The surface morphology and the thermal stability of these two polymers were investigated by scanning electron microscopy (SEM) and thermal gravimetric analysis (TGA), respectively. The optical properties of compounds (1) and (2) were also explored. The results confirmed that the promising new strategy of the synthesis process based on modifying polystyrene sulfonic acid by encapsulation of γ –cyclodextrin significantly enhanced the thermal stability and the optical properties of the final product making it suitable for a wide range of industrial uses.

Craft Entrepreneurship on Environmental Waste Recycling in Malang Municipality

<p>The purpose of this study is to examine the effectiveness of <em>Sanggar Asta Karya Panca Wiguna</em> (AKPW) in Malang Municipality, Indonesia, in garbage-recycling business. Garbage has been turned into valuable and artistic products that is also environmentally friendly. The products produced include <em>dammar kambang</em>, <em>suket wayang</em>, lampshade, and others. This study uses qualitative method to examine the entrepreneurship behaviour of the AKPW. The key informant is the chairperson of the studio. AKPW works in the fields of environment, education, economy, culture, and health. The result of the research shows that the garbage-recycling business takes creativity and product innovation based on persistence and perseverance. AKPW works on the concept of social green entrepreneurship that combines the concept of three pillars of ecological, economic, and social sustainability through art and culture. AKPW should conduct more efforts to socialize more intensively.</p>

Learning Materials on Environmental Change of Waste and Waste Recycling With SETS Bervisi Module to Improve Student Learning Outcomes in SMA

The development of science curriculum aims to achieve the dimensions of knowledge competence, scientific work, and scientific attitude as daily behavior in interacting with society, environmental and technological utilization. Teaching materials are used in the form of book packages and not yet available learning modules. This study aims to determine the feasibility and effectiveness of SETS biological module vision of environmental change and recycling of waste as teaching materials. This research is a research and development with a quasi-experimental design. The design of this study used a pretest-posttest control group design pattern. The population in this study were all students of class X MIA SMA N 2 Purbalingga, with class X MIA 3 sample as experiment class, and class X MIA 2 as control class. The product was developed in the form of a Biology learning module with SETS vision of recycled materials, waste and environmental waste recycling. The prerequisite test includes the normality test of pretest learning results, with α = 0.05 with the initial conditions of the control class and the experiments not significantly differing. The result of posttest obtained then analyzed by t-test. The result of t-test analysis obtained t arithmetic price> t table price 10,58> 1,67, it can be stated that there is a significant difference between the result of control study and student experiment class. Based on the result of the research, it is concluded that 1) Biology Module SETS is suitable to be used as teaching materials, 2) the use of SETS biology module to study environmental change, waste and waste recycling effectively improve student learning outcomes.
