Abstract

Clay soil is a type of soil characterized by high plasticity and strong sensitivity to changes in water content, which can significantly affect construction stability. Shear strength parameters, namely cohesion (c) and internal friction angle (φ), are essential factors in geotechnical analysis; however, their determination generally requires considerable time and cost. Therefore, an alternative approach is needed by utilizing the Plasticity Index (PI) as a predictive parameter for soil shear strength. This study aims to analyze the relationship between the plasticity index and the shear strength parameters of clay soil in Manyar District, Gresik Regency.The research employed a quantitative approach based on laboratory testing, including Atterberg limits tests to determine the plasticity index and direct shear tests to obtain cohesion and internal friction angle values. The analysis was conducted at several soil depths using descriptive and empirical regression approaches.The results indicate that the plasticity index ranges from 41.97% to 47.84%, with cohesion values between 0.25–0.39 kg/cm² and internal friction angles ranging from 7° to 15°. The analysis shows that an increase in the plasticity index tends to be followed by an increase in cohesion and a decrease in the internal friction angle. These conditions indicate that the soil at the study site is predominantly cohesive with a relatively high deformation potential. The findings of this study are expected to serve as a preliminary approach for estimating shear strength parameters in similar clay soil conditions.

Abstract

Solidaritas sosial menjadi isu penting dalam kehidupan bermasyarakat, khususnya pada kelompok masyarakat yang masih menghadapi keterbatasan ekonomi dan akses terhadap kebutuhan dasar. Permasalahan yang diangkat dalam kegiatan ini adalah rendahnya kesejahteraan sebagian masyarakat serta perlunya penguatan hubungan sosial melalui aksi nyata kepedulian bersama. Kegiatan ini bertujuan untuk memperkuat solidaritas sosial sekaligus membantu pemenuhan kebutuhan dasar masyarakat melalui kegiatan berbagi sembako dan pakaian layak pakai. Metode yang digunakan adalah pendekatan pemberdayaan masyarakat berbasis aset, yang menekankan pada pemanfaatan potensi sosial, budaya, dan jaringan yang dimiliki masyarakat, serta dilengkapi dengan analisis kekuatan, kelemahan, peluang, dan ancaman untuk melihat kondisi internal dan eksternal program. Kegiatan dilaksanakan secara partisipatif dengan melibatkan mahasiswa, dosen, perangkat desa, dan masyarakat setempat melalui tahapan perencanaan, persiapan, pelaksanaan, dan evaluasi. Hasil kegiatan menunjukkan bahwa bantuan tersalurkan dengan tepat sasaran dan mampu meningkatkan interaksi sosial, rasa kebersamaan, empati, serta kepercayaan antara mahasiswa dan masyarakat. Selain memberikan manfaat langsung bagi penerima, kegiatan ini juga menjadi sarana pembelajaran kontekstual bagi mahasiswa dalam menumbuhkan tanggung jawab sosial. Kesimpulannya, kegiatan berbagi sembako dan pakaian layak pakai efektif sebagai upaya penguatan solidaritas sosial yang berkelanjutan serta mampu mempererat hubungan antara perguruan tinggi dan masyarakat.

Abstract

Kontribusi UMKM terhadap perekonomian cukup dominan, namun pelaku usaha ini masih dihadapkan pada berbagai permasalahan, khususnya terkait rendahnya produktivitas, keterbatasan efisiensi operasional, serta belum optimalnya adopsi teknologi dalam proses produksi. Kegiatan Pengabdian kepada Masyarakat (PKM) ini bertujuan untuk meningkatkan pengetahuan dan keterampilan pelaku UMKM melalui sosialisasi pemanfaatan teknologi tepat guna yang sesuai dengan kebutuhan dan kondisi usaha. Metode yang digunakan adalah pendekatan partisipatif berbasis kelompok yang meliputi tahap identifikasi kebutuhan, sosialisasi, pelatihan, pendampingan, dan evaluasi. Kegiatan ini melibatkan 20 pelaku UMKM di Surabaya dengan latar belakang usaha yang beragam. Penilaian terhadap peningkatan pemahaman peserta dilakukan dengan membandingkan hasil sebelum dan sesudah kegiatan. Temuan menunjukkan lonjakan yang sangat nyata, di mana nilai awal sebesar 38,5% meningkat menjadi 95,5%, atau mengalami kenaikan sebesar 57% yang termasuk dalam kategori tinggi. Selain itu, peserta juga menunjukkan peningkatan keterampilan teknis dalam penggunaan teknologi serta kesiapan dalam mengimplementasikannya pada proses produksi. Kegiatan ini juga mendorong terjadinya pembelajaran kolektif dan efek multiplikasi antar pelaku UMKM. Secara keseluruhan, program ini menunjukkan keberhasilan dalam memperkuat produktivitas, meningkatkan efisiensi operasional, serta mendorong daya saing UMKM melalui penerapan teknologi yang relevan dan berkesinambungan.

Abstract

Household appliances play an important role in supporting daily activities. However, the high rate of equipment damage and the limited technical knowledge among the community, especially housewives, often lead to dependence on repair services and increased household expenses. This community service program aimed to improve the ability of housewives to identify damage and perform simple repairs on household appliances independently. The program applied an educational and participatory approach through preparation, implementation, and evaluation stages. The implementation included the delivery of basic technical materials, demonstrations, hands-on practice, and interactive discussions. Data collection methods consisted of observations, questionnaires in the form of pre-tests and post-tests, interviews, and documentation, while data analysis employed both quantitative and qualitative descriptive approaches. The results showed a significant improvement in participants’ understanding, indicated by an increase in the percentage of correct answers from 15% to 80%. In addition, participants demonstrated better practical skills and greater confidence in carrying out simple repairs independently. This activity not only enhanced participants’ technical competence but also contributed to household cost efficiency and the reduction of electronic waste. Therefore, the program is considered effective in promoting community self-reliance and has the potential to be sustainably developed.

Abstract

Sanitation and drainage problems at the household level continue to pose challenges in residential environments, largely driven by inadequate understanding of proper domestic waste handling. This community engagement initiative was designed to improve public knowledge and raise awareness of effective and sustainable sanitation and drainage practices. The activity was conducted in Ngaresrejo Village, Sidoarjo Regency, involving approximately 25 participants through a participatory approach. The methods applied included preliminary surveys, interactive educational sessions, audio-visual demonstrations, and evaluation using pre-test and post-test instruments. The results indicated a substantial improvement in participants’ understanding, increasing from approximately 21,2% at the initial stage to 88,8% after the intervention, representing an improvement of about 67,6%. In addition, participant attendance and engagement were high, and most participants expressed willingness to implement improved sanitation practices at the household level. All program success indicators were achieved, including increased awareness and the development of educational materials. Accordingly, the initiative proves effective in strengthening public understanding and shows promise in supporting long-term improvements in environmental conditions within residential settings.
