<span lang="EN-US">The relocation of the capital city of Indonesia needs the utmost support for its sustainability. This paper is an explorative study on the pro-environmental behavior (PEB) of students from the buffer cities closest to the new capital city. Data were collected using a questionnaire based on the two major environmental values and appreciation instruments. The questionnaire contained 21 items that measured PEB in relation to three aspects: preservation, utilization, and appreciation. Data were collected from 280 junior high school students who participated in an online questionnaire. The data analysis used descriptive statistics and correlations. Utilization was identified as having the highest score among the three aspects, indicating that most students in the buffer cities hold exploitative utilitarian preferences for nature. Interventional education programs are needed to reduce human over-exploitation of the environment and prevent further environmental degradation. The highest correlation was found between appreciation and preservation, which was significant and positive. Gender was not a variable that affected PEB. However, the location of the buffer cities was the factor that showed the most significant differences in the scores. Our results could provide relevant insights for the design of environmental education to support the sustainability of Indonesia’s new capital city.</span>
Although a huge number of studies enhancing pro-environmental behavior (PEB), the environmental quality is still in poor condition. Enhancing PEB needs to consider some aspects, such as the value and location. Pre-service physics teachers have a role in shaping students’ PEB because environmental issues are part of the high school physics curriculum. This study aimed to investigate the link between the location, and values (biospheric, altruistic, egoistic, and hedonic), from two different locations in Indonesia. The modified and translated 2-MEV, and E-PVQ scales were used. This study concluded that the values in both locations are in the very high category, in which the values are correlated to PEB. The strongest correlated value is an egoistic value that is related to the self-enhancement indicating the need for self-enhance approaches in the class to promote PEB. The different locations which are in the same country didn’t show a significant difference in both values and PEB. Thus, future study could conduct their research in a larger area with a different culture to explore the relationship between PEB with location or other demographic aspects, and the development of activities to enhance PEB need to consider the strong relationship between PEB with egoistic value.
Pro-environmental Behavior (PEB) yang diterapkan dalam kurikulum merupakan upaya percepatan perbaikan lingkungan. Melalui penelitian ini diharapkan mampu memberikan gambaran kategori PEB calon guru Fisika yang telah mendapatkan pembelajaran dengan kurikulum terintegrasi PEB. Penelitian dilakukan menggunakan pendekatan kuantitatif, dengan pengambilan sampel secara purposive sampling. Instrumen yang digunakan merupakan angket dua dimensi 2-Major Environmental Values (2-MEV) yang telah dialihbahasakan dan disesuaikan dengan konteks Indonesia. Secara keseluruhan, responden yang telah mengisi angket sejumlah 63 calon guru Fisika yang telah menempuh mata kuliah berbasis lingkungan. Hasil penelitian menunjukkan bahwa mayoritas calon guru Fisika berada pada kategori Tinggi, dan tidak ada calon guru yang berada pada kategori rendah. Temuan ini mampu memperkuat bahwa aspek pendidikan, yang dalam hal ini diimplementasikan dalam kurikulum berbasis Hutan Tropika Basah dan Lingkungannya (HTB+L) ditambah dengan pembiasaan di lingkungan Universitas mampu berdampak positif terhadap PEB. Pada lingkup universitas mulawarman telah dilakukan upaya pembiasaan PEB melalui disediakannya sarana dan prasarana ramah lingkungan, hingga berbagai kegiatan terintegrasi PEB. Kurikulum berbasis lingkungan memiliki potensi dalam peningkatan PEB calon guru, baik melalui pembelajaran di kelas, dan berbagai kegiatan yang bersifat pembiasaan. Selain implementasi kurikulum yang mampu memperkuat pengetahuan lingkungan calon guru, perlu untuk dilengkapi dengan kegiatan kemahasiswaan atau pembiasaan yang berkaitan dengan lingkungn. Pada penelitian ini masih terbatas pada analisis aspek pengetahuan dalam kurikulum terhadap PEB, sehingga diperlukan penelitian lanjutan yang mengkaji aspek-aspek lain pembentuk PEB secara teoretis.
Salah satu upaya mengatasi permasalahan pencemaran lingkungan yang diakibatkan oleh limbah detergen adalah dengan pemanfaatan bahan alami sebagai pengganti surfaktan. Penelitian ini bertujuan untuk menghasilkan detergen berbahan aktif biosurfaktan daun kelor dengan metode Prinsip Rotary Evaporator Sederhana (PRES). Pemanfaatan daun kelor (Moringa olifera) dilakukan dengan mengekstraksi daun kelor menggunakan metode maserasi hingga menghasilkan biosurfaktan, yang kemudian diolah menjadi detergen cair. Untuk menguji sediaan biosurfaktan maupun detergen cair, dilakukan beberapa uji, yaitu organoleptik, pH, bobot jenis, stabilitas busa, daya detergensi, dan cemaran dari limbah detergen cair kemudian dibandingkan dengan detergen komersial. Hasil detergen cair menggunakan metode PRES menunjukkan mutu detergensi yang sebanding dengan detergen komersial, karena memiliki stabilitas busa mencapai 97%, dengan daya detergensi mencapai 80%, namun tingkat limbah cemaran yang tinggi. Penelitian ini menunjukkan bahwa penggunaan metode PRES dapat menghasilkan detergen cair dengan stabilitas busa dan mutu detergen yang baik, namun memerlukan penelitian lebih lanjut untuk dapat meminimalkan tingkat cemaran limbah yang dihasilkan.
