Abstract

Kuliah Kerja Nyata (KKN) pada masa pandemi covid-19 ini tentu sangat berbeda dengan KKN sebelumnya. Pada masa pandemi covid-19 ini kita tidak bisa langsung bertemu dengan masyarakat untuk melaksanakan KKN. KKN kali ini bisa dilaksanakan secara langsung dengan tetap menjalankan protokol kesehatan secara ketat dan bisa dilaksanakan secara daring, contohnya dengan mengadakan webinar. Webinar ini bertujuan untuk menyalurkan ilmu-ilmu yang sudah dipelajari sebagai bentuk pengabdian kepada masyarakat. Salah satu contoh KKN daring ini adalah webinar yang diselenggarakan oleh kelompok 4 KKN Teknik Sipil. Webinar yang dilaksanakan oleh kelompok 4 ini terbagi menjadi 4 webinar dengan masing-masing webinar memiliki judul yang berbeda-beda. Hasil dari webinar ini menunjukkan bahwa kegiatan KKN sebagai wujud pengabdian kepada masyarakat pada masa pandemi covid-19 ini masih bisa dirasakan manfaatnya oleh masyarakat dan peran Mahasiswa masih bisa dilakukan dengan rangkaian program atau kegiatan inovatif serta tetap menjalankan protokol kesehatan untuk mencegah penyebaran wabah covid-19. Metode yang digunakan tentunya secara daring, dikarenakan kita berorientasi kepada situasi yang sedang terjadi di masa pandemic seperti ini, adapun yang dilaksanakan secara luring seperti untuk sosialisasi, tetapi tetap dengan menggunakan protokol kesehatan.

Abstract

Real Work Lecture (KKN) is a form of community service activity by students with a cross-scientific and sectoral approach at certain times and regions in Indonesia. The implementation of KKN activities lasts between one month and takes place in an area at the village level of Sindangmekar. The method used is a field survey method, outreach about workshops, especially in the utilization of natural resources into products that have high selling power and as business opportunities for the community and understanding of digital literacy. The aim is to increase skills and knowledge regarding the use of digital devices that are good and right, so that people can develop smart, creative and productive attitudes which are an option in the learning that has been carried out. When the activity is carried out, all involved are required to comply with the health protocol. The result of this activity is that people can apply knowledge when needed.

Abstract

The construction industry faces increasing pressure to adopt more sustainable practices, particularly in reducing the environmental impact of cement production, which is responsible for significant CO₂ emissions and the depletion of natural resources. One promising strategy is to partially replace cement with industrial waste materials that possess cementitious properties. This study examines the potential of tannery sludge, a hazardous byproduct of the leather tanning process, as a partial substitute for cement in the manufacturing of paving blocks. The sludge contains valuable oxides such as CaO, Al₂O₃, and Fe₂O₃, which can contribute to the binding characteristics required in concrete applications. An experimental approach was conducted to evaluate the performance of paving blocks containing 0%, 1%, 3%, and 5% tannery sludge by weight of cement. Tests included compressive strength, wear resistance, water absorption, resistance to sodium sulfate, and chemical composition analysis using X-ray fluorescence (XRF). The results revealed that all sludge-containing mixtures maintained compressive strength values exceeding the minimum threshold for class B paving blocks, making them suitable for moderate-load applications such as parking areas and pedestrian pathways. Wear resistance results placed all specimens in class A, indicating high surface durability. However, increased water absorption was observed with higher sludge content, potentially due to the porous nature of the sludge. The sodium sulfate resistance test highlighted the need for further enhancement, as weight fluctuations indicated vulnerability in chemically aggressive environments. XRF analysis confirmed the compatibility of the sludge composition with cement standards. In conclusion, tannery sludge demonstrates technical feasibility as a sustainable alternative to cement in the production of paving blocks. Its use offers environmental and economic advantages, though further research is needed to optimize performance and ensure long-term durability under various conditions.
