Abstract

The increasing volume of plastic waste poses significant environmental challenges, particularly due to its slow degradation and the accumulation of non-biodegradable materials in landfills. This study explores an alternative utilization of plastic waste by transforming it into a binding material for paving blocks. A quantitative experimental approach was employed to examine how varying proportions of molten plastic and sand influence the physical and mechanical properties of paving blocks. Four mixture variations were tested 100% plastic, 75% plastic : 25% sand, 50% plastic : 50% sand, and 25% plastic : 75% sand, each molded into standard 20 × 10 × 8 cm specimens and evaluated for compressive strength, water absorption, and abrasion resistance. The results demonstrate a clear trend in which higher plastic content leads to improved mechanical performance. The 75% plastic composition exhibited the best overall results, achieving a compressive strength of 11.64 MPa, low water absorption of 1.32%, and an abrasion rate of 0.098 mm/min. The 100% plastic variation also performed well, with a compressive strength of 10.82 MPa and the lowest abrasion values ranging from 0.037 to 0.062 mm/min. In contrast, the low-plastic mixture (25%) showed a marked decline in performance, indicated by a compressive strength of 8.91 MPa, water absorption of 3.78%, and abrasion rates of 0.201–0.226 mm/min. Based on SNI 03-0691-1996, PB100 and PB75 meet Class A quality standards, PB50 is categorized as Class C, and PB25 falls into Class D. Overall, the findings confirm that plastic waste can serve as an effective binder, producing paving blocks with low porosity, high abrasion resistance, and enhanced mechanical properties. These results highlight the promising potential of plastic waste as a sustainable construction material, contributing to both waste reduction and the development of environmentally friendly building products.

Abstract

Penerapan Sistem Manajemen Keselamatan Konstruksi (SMKK) merupakan langkah strategis dalam menciptakan lingkungan kerja yang aman dan efisien di sektor konstruksi. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengevaluasi efektivitas kegiatan sosialisasi penerapan SMKK pada proyek pembangunan Stadion B.J. Habibie di Kota Parepare. Sosialisasi dilaksanakan melalui pendekatan multimodal, yaitu kombinasi antara teori, media visual, dan praktik lapangan yang melibatkan 32 peserta dari pihak kontraktor dan konsultan proyek. Pengukuran dilakukan dengan metode pre-test dan post-test menggunakan instrumen kuesioner berbasis skala Gutman. Hasil analisis statistik menggunakan uji Wilcoxon menunjukkan nilai signifikansi sebesar 0,000 (p < 0,005), yang menandakan adanya perubahan sikap yang signifikan pada peserta terhadap keselamatan kerja setelah mengikuti sosialisasi. Temuan ini memperkuat bukti bahwa kegiatan edukatif berbasis proyek nyata mampu meningkatkan kesadaran dan kepatuhan terhadap prinsip-prinsip SMKK. Edukasi yang dirancang secara kontekstual dan partisipatif tidak hanya berdampak pada peningkatan sikap, tetapi juga membentuk budaya kerja yang lebih aman dan bertanggung jawab di lapangan. Oleh karena itu, kegiatan sosialisasi serupa direkomendasikan untuk diimplementasikan secara berkelanjutan pada proyek-proyek konstruksi lainnya, terutama yang berskala besar dan melibatkan banyak tenaga kerja.

Abstract

Wilayah Kota Parepare merupakan salah satu daerah rawan banjir akibat kombinasi topografi dataran rendah, curah hujan tinggi, dan sistem drainase yang belum optimal. SMK Negeri 1 Parepare menjadi salah satu sekolah yang terdampak banjir, namun belum memiliki program edukasi kebencanaan yang terstruktur. Kegiatan pengabdian ini bertujuan untuk meningkatkan pemahaman dan kesiapsiagaan siswa terhadap risiko banjir melalui edukasi mitigasi berbasis ceramah, diskusi interaktif, dan pemutaran video simulasi. Metode pelaksanaan terdiri dari empat tahapan: perencanaan, persiapan, pelaksanaan, dan evaluasi. Sebanyak 71 siswa terlibat dalam kegiatan yang diselenggarakan di aula sekolah. Penilaian pemahaman dilakukan dengan metode pretest dan post-test menggunakan soal pilihan ganda yang relevan dengan materi mitigasi banjir. Hasil pretest menunjukkan rata-rata pemahaman awal sebesar 70,49%, dengan sebagian besar siswa berada pada kategori sedang hingga rendah. Setelah kegiatan edukasi, rata-rata nilai post-test meningkat signifikan menjadi 90,14%, menunjukkan adanya peningkatan pemahaman sebesar 30,47%. Peningkatan ini mengindikasikan bahwa pendekatan edukatif yang digunakan efektif dalam meningkatkan literasi kebencanaan di kalangan siswa. Dengan demikian, kegiatan pengabdian ini dinilai berhasil dalam membekali siswa dengan pengetahuan dasar dan kesiapsiagaan menghadapi bencana banjir di lingkungan sekolah.

Abstract

This study introduces a method using layered plastic blending technology to combine three primary types of plastic waste (PET, PP, and LDPE) with sand. The objective is to analyze the effects of plastic-sand composition variations on the mechanical properties of paving blocks, including water absorption, compressive strength, and abrasion resistance. The research was conducted experimentally through a plastic melting and hot-mixing process with sand using four composition ratios: 100% plastic: 0% sand, 75% plastic: 25% sand, 50% plastic: 50% sand, and 25% plastic: 75% sand. Results indicate that the 75% plastic: 25% sand mixture has the highest compressive strength of 11.64 MPa. The 100% plastic: 0% sand mixture exhibited the lowest absorption (<3%) and the best abrasion resistance (<0.062 mm/min). Increasing sand content generally reduced mechanical performance due to the inadequate distribution of plastic in coating the aggregate particles. Overall, plastic waste-based paving blocks demonstrate strong potential as an alternative construction material. Nevertheless, long-term environmental durability testing is recommended to ensure their applicability under real field conditions.
