Abstract

The current technology for using recycled materials in road preservation work is very helpful in maintaining the sustainability of the materials used. Waste from road materials that will be repaired can be reused for new foundation layers. The aim of this research is to obtain a design for the percentage of cement, percentage of emulsified asphalt, unconfined compressive strength and optimum water content in accordance with the applicable engineering specifications so that it can be proven that the existing material from the top foundation layer and asphalt layer can still be used as a new foundation layer. The research method involves conducting experiments on existing materials by conducting laboratory tests on samples of top foundation layer aggregate and existing asphalt in the Cikarang Industrial Area. The experiment was carried out at the Jakarta State Polytechnic Civil Engineering Laboratory with 9 test samples. The results obtained for the recycled foundation layer were that the design cement required was 30.8 grams and 53.1 grams of emulsified asphalt for an area of ​​1m2 with a 7 day unconfined compressive strength obtained from nine samples for variations in cement content of 1%, 3%, and 5% maximum 2.81MPa, so the optimum cement content is 3.6%.

Abstract

Limbah organik rumah tangga seperti nasi basi dan teh celup bekas sering dibuang tanpa pengelolaan, padahal berpotensi diolah menjadi pupuk cair organik. Namun, warga belajar di PKBM masih memiliki kesadaran dan keterampilan yang rendah dalam pemanfaatan limbah tersebut secara produktif. Kegiatan pengabdian ini bertujuan untuk meningkatkan pengetahuan dan keterampilan warga belajar PKBM Salsabila Kota Langsa dalam mengolah limbah dapur menjadi pupuk cair berbasis prinsip zero waste. Metode pelatihan dilakukan secara partisipatif melalui ceramah, demonstrasi, dan praktik langsung. Pengabdian dilakukan pada 30 orang warga belajar pada PKBM Salsabila Kota Langsa dan Hasil evaluasi menunjukkan peningkatan nilai pemahaman peserta dari rata-rata 30 (pre-test) menjadi 80 (post-test). Sebanyak 70% peserta berhasil melakukan praktik secara mandiri dengan hasil fermentasi yang menunjukkan kualitas pupuk cair yang baik. Temuan ini menunjukkan bahwa pendekatan pelatihan yang berbasis kontekstual dan praktik langsung sangat efektif diterapkan di pendidikan nonformal untuk membangun keterampilan, kesadaran lingkungan, dan pemberdayaan warga belajar.
