Abstract

Pengenalan kebersihan harus ditanamkan pada anak sejak usia dini. Proses pengenalan dan pemahaman akan arti kebersihan diri dan lingkungan memerlukan sarana atau media, sehingga anak dengan cepat dapat memahami dan mengaplikasikannya. Salah satu media yang dapat diperkenalkan kepada anak dalam proses pembelajaran sanitasi adalah wastafel inovatif. Peran dan fungsi wastafel ini sebagai tempat untuk mencuci tangan untuk anak. Tujuan yang akan dicapai adalah anak dapat mencuci tangan dengan baik dan benar. Setiap anak harus dapat melakukan kegiatan cuci tangan dengan sabun setelah anak melakukan kegiatan bermain untuk menghindari penyebaran penyakit. Bentuk wastafel inovatif didesain menarik dengan memperhatikan profil dan karakter anak. Bentuk dan warna merupakan hal yang dapat dieksplorasi sehingga anak tertarik untuk melakukan proses sanitasi pada dirinya. Penerapan konsep pembelajaran sanitasi dilakukan di sekolah PAUD-RA Bunda Asih. Pemilihan sekolah berdasarkan pada belum tersedianya media untuk mencuci tangan dalam bentuk wastafel, sehingga anak mengabaikan kebersihan diri karena terlepas dari pengawasan para guru. Kondisi ini menjadi kendala bagi guru untuk mengenalkan sanitasi hidup sehat secara baik dan benar. Berdasarkan permasalahan tersebut maka dilakukan pengembangan desain sanitasi yang menarik kreatif dan inovasi yang merangsang kreatifitas dan kebiasaan anak untuk selalu menjaga kebersihan diri dan membiasakan mencuci tangan untuk kebersihan dirinya.

Abstract

Population growth has led to increased runoff and wastewater flowing into drainage channels. This study, therefore, aims to evaluate the drainage capacity of selected channels in Medan City and whether they can still serve the community in the next 10, 20 and 30 years. The observed channel starts from Taduan Street No. 1 to Taduan Street No. 153, with a length of 1,000 m. This evaluation considers population growth, the volume of domestic wastewater, the volume of runoff, the generation of sediment in channels, and evapotranspiration as part of the water cycle. Monthly maximum rainfall data from 2012-2021 from the BMKG Sampali Medan and population data along Taduan are used in the review in this article. Based on the investigation, it is known that the volume of drainage on Taduan Street is no longer able to serve the community even for 2032. It is necessary to review and redesign the dimensions to ensure that wastewater from household activities and runoff does not have a negative impact, especially during the rainy season. With as many as 48 injection wells and the Watershed expansion, it is expected to reduce inundation. Keywords:   Drainage channel, Domestic wastewater, Evaluation,  Medan, Rainwater

Abstract

Data SIPSN tiga tahun terakhir menunjukkan timbulan sampah di Kabupaten Langkat meningkat 24,71% atau dari yang awalnya 152.099 menjadi 189.685 ton. Lebih dari 42% timbulan sampah disumbangkan oleh sektor domestik yang seharusnya dapat dikelola sedekat mungkin dari sumbernya. Dengan demikian, kegiatan pengabdian kepada masyarakat ini bertujuan memberikan pelatihan agar masyarakat lebih memahami cara mengurangi timbulan sampah dengan mengubahnya menjadi produk yang bermanfaat. Pelatihan dilaksanakan pada 5 Agustus 2021 di Rumah Komunitas Pohon Rindang, Desa Perkebunan Bukit Lawang, kepada 43 anak usia 8-15 tahun. Metode yang digunakan adalah penyuluhan interaktif dengan memberikan demonstrasi cara membuat keranjang takakura dan stringbag. Keranjang takakura 45x37x57 cm dapat menampung hingga 1,5 kg sampah organik basah per hari, sedangkan pembuatan pakaian bekas menjadi stringbag dapat menunda pembuangan material ke TPA. Dalam jangka panjang kegiatan ini diharapkan menjadi kebiasaan baru bagi masyarakat dalam mengelola sampah untuk menjadikan Desa Perkebunan Bukit Lawang sebagai desa pariwisata yang berkelanjutan.

Abstract

Pertumbuhan penduduk telah menyebabkan peningkatan debit limpasan hujan dan air limbah yang dialirkan ke saluran drainase. Penelitian ini maka bertujuan mengevaluasi volume drainase di Jalan Taud, Kota Medan, apakah tetap dapat menampung air buangan hingga perkiraan 50 tahun mendatang. Saluran yang diamati mulai dari Rumah Kosan (Jalan Taud No. 112) hingga unit usaha Gulo Pangkas (Jalan Taud No. 16) dengan panjang 1.000 m. Evaluasi ini mempertimbangkan pertambahan jumlah penduduk, debit air limbah domestik, debit limpasan hujan, timbulan sedimen, serta proses evapotranspirasi sebagai bagian dari siklus air. Berdasarkan investigasi, diketahui volume drainase di Jalan Taud saat ini masih dapat melayani masyarakat hingga tahun 2047. Hasil evaluasi yang dilakukan pada saluran drainase terpilih di Jalan Taud, Kota Medan, diperoleh kesimpulan bahwa drainase tetap dapat menampung air buangan dari campuran limpasan hujan dan air limbah domestik hingga 25 tahun mendatang. Intensitas curah hujan pada 10 tahun mendatang di tahun 2032 berkisar 5,87 mm/jam, 6,04 mm/jam di tahun 2047, dan 6,56 mm/jam di tahun 2072; sedangkan debit air limbah total yang dihasilkan dari aktivitas domestik adalah 10.71 x 10-2 L/orang/hari (2032), 12.24 x 10-2 L/orang/hari (2047), dan 17.24 x 10-2 L/orang/hari (2072). Dengan panjang saluran yang diamati 1.000 m, lebar saluran rata-rata adalah 0,82 m, dan kedalaman 0,90 m, didapatkan volume drainase eksisting adalah 590,4 m³. Perlu upaya pengelolaan rutin seperti pembersihan saluran dari sampah dan sedimen secara berkala, serta sosialisasi kepada masyarakat untuk menjadikan drainase tetap berfungsi sebagaimana mestinya.

Abstract

Clay is a type of soil that is generally characterized by its low load-bearing capacity. Due to the nature of clay minerals, which easily absorb and store water, clay soil is not generally considered suitable for use as a basic building material. This study analyzes changes in the unconfined compressive strength and shear strength of clay soil mixed with rice husk ash (RHA), NaOH, and a combination of rice husk ash and NaOH. The research method involves laboratory tests on original soil samples and soil samples that have been stabilized with varying levels of additives. The results showed that adding rice husk ash, NaOH, or both changed the properties in all tested samples. Unconfined compressive strength testing with varying amounts of rice husk ash (8%, 17%, 25%) showed the highest compressive strength increase of 28.19% at 8% RHA. Meanwhile, adding different amounts of solid NaOH (10%, 14%, and 25%) did not increase the soil's unconfined compressive strength. Mixing rice husk ash and NaOH also did not increase the soil's unconfined compressive strength; rather, it decreased the original soil's rigidity. Direct shear strength tests with RHA variations (8%, 17%, and 25%) showed the greatest increase at 8% of the original soil content, reaching 28.9%. This value decreased with an increased RHA percentage. Adding solid NaOH at different ratios (10%, 14%, and 25%) showed the greatest increase at 10%, with an increase of 14.68%; however, it decreased with increasing NaOH content. The mixture of RHA and NaOH increased in all variations. The highest direct shear strength value occurred in the 25% RHA + 25% NaOH mixture, which increased by 54.13% compared to the original soil. This study showed that RHA can increase soil strength through reactions with water and soil particles. However, these results emphasize the importance of selecting the appropriate types and ratios of stabilizer materials in accordance with engineering requirements.

Abstract

Mathematical problem-solving is a fundamental competence for civil engineering students, as it underpins their ability to analyze and address engineering-related challenges. However, current instructional practices in higher education remain largely procedural and insufficiently integrate digital technologies and meaningful contexts, making it difficult for students to connect abstract mathematical concepts with real-world engineering applications. This condition often leads to low engagement and limited development of critical thinking skills. This study aims to develop and evaluate the effectiveness of an Ethno-STEAM-based digital mathematics learning model in enhancing students’ mathematical problem-solving abilities. A Research and Development (R&D) approach was employed using the Borg and Gall model adapted from Dick and Carey. The findings indicate significant improvements in analytical skills, understanding of integral concepts, engagement, and critical thinking. These results suggest that the Ethno-STEAM approach provides a more contextual, interactive, and relevant learning experience, while supporting the development of 21st-century competencies in engineering education.
