Abstract

Leather tanning activities in the Piyungan industrial region employ heavy metal chromium (Cr) as the primary component in the tanning process, resulting in heavy metal chromium contamination along the Opak River. Apart from its effect on water, chromium will be disseminated in sediment and biota in the Opak River, particularly aquatic plants with phytoremediation characteristics. The purpose of this study is to establish the distribution pattern of chrome pollution along the downstream bank of the Opak River utilizing water, sediment, and aquatic plant components. The study was done at five test sites in April, May, and June. The chromium concentration was then measured using the AAS (Atomic Absorption Spectrophotometer) technique and assessed using ANOVA. The test results show that the Opak River has been contaminated by the heavy metal chromium, with the highest distribution of contamination in sediment samples, followed by samples of water spinach plants (Ipomoea aquatica Forsk) with an average of 0.210 mg/L, and samples of water hyacinth plants (Eichornia crassipes Mart. Solms) with an average of 0.152 mg/L.

Abstract

The extensive usage of social media in today's globalized society has had an impact on the education industry. To undertake academic and non-academic activities, social media are usually utilized by students in higher distance education to communicate with peers and instructors during the learning process. Some of them had difficulty adjusting to the new method of learning. The goal of the study is to examine how they utilize social media in relation to their access behaviour. This online survey received responses from 549 individuals in purposive samplingThe finding shows a considerable correlation between access capacity behaviour and social media usage. It is evident that access habits, which are supported by behaviour and accessibility, have a substantial effect on the use of entertainment and socialization. Based on these findings, it is understandable that social media offer more abundantly relaxing contents that easily tempts students than the serious ones. In order to address this issue, educational institutions must develop several easy and engaging media-based educational tools.

Abstract

Plastic waste represents a significant global environmental challenge due to its resistance to natural degradation and its widespread pollution impact. In Indonesia, the management of household plastic waste remains inadequate, largely due to limited public awareness and engagement. To address this issue, a community-based initiative was developed to build local capacity for managing plastic waste by creatively repurposing used water gallons into functional trash bins. This approach involved direct, hands-on training and ongoing mentoring of residents in Bangi, Woromarto Village, Purwoasri District, Kediri Regency. The effectiveness of the program was evaluated through participatory observation and systematic documentation of the products created by community members. The findings revealed a significant increase in community participation in recycling activities and the strategic placement of the repurposed trash bins throughout the village, thereby improving local waste management practices. Beyond providing a practical solution for reducing plastic waste accumulation, this initiative fostered positive behavioral changes by encouraging residents to adopt more responsible and sustainable practices centered on environmental stewardship and maximizing the value of discarded materials. Permasalahan sampah plastik merupakan isu global yang memberikan dampak serius terhadap pencemaran lingkungan karena sifat plastik yang sangat sulit terurai secara alami. Di Indonesia, pengelolaan sampah rumah tangga terutama plastik, masih belum optimal akibat rendahnya tingkat kesadaran dan partisipasi masyarakat dalam mengelola limbah tersebut. Untuk mengatasi permasalahan ini, kegiatan yang dilaksanakan bertujuan untuk meningkatkan kapasitas masyarakat dalam pengelolaan sampah plastik melalui pemanfaatan galon bekas sebagai bahan utama pembuatan tempat sampah. Pendekatan yang digunakan adalah metode partisipatif melalui pelatihan dan pendampingan langsung kepada warga Dusun Bangi, Desa Woromarto, Kecamatan Purwoasri, Kabupaten Kediri. Evaluasi keberhasilan kegiatan dilakukan dengan observasi partisipatif dan dokumentasi hasil karya warga. Hasil kegiatan menunjukkan peningkatan keterlibatan masyarakat dalam proses daur ulang serta tersebarnya tempat sampah hasil olahan di berbagai titik desa. Kegiatan ini tidak hanya memberikan solusi praktis dalam pengurangan sampah plastik, tetapi memicu perubahan perilaku masyarakat menuju pengelolaan lingkungan yang lebih bertanggung jawab, berkelanjutan, dan bernilai guna.
