Abstract

Jurang senggani merupakan salah satu obyek wisata yang berlokasi di dusun Nglurup, kecamatan Sendang, kabupaten Tulungagung, merupakan salah satu obyek wisata andalan Kota Tulungagung karena pesona air terjun dan perkebunan kopi nya yang masih alami karena berada di dataran tinggi. Disamping keindahan alam yang disajikan terdapat kendala yaitu akses nya, untuk mencapai obyek wisata jurang senggani aksesnya masih berupa tanah lempung yang licin dan konturnya bergelombang karena sifat lempung yaitu ekspansif. Tujuan pengabdian masyarakat ini yaitu memberikan pendampingan terkait pengelolaan sumber daya alam yang berada disekitar area wisata jurang senggani agar mereka mampu memaksimalkan sumber daya alam yang tersedia, serta memberikan pengetahuan terkait sistem pengerjaan struktur jalan dengan metode pasangan batu. Adapun metode yang digunakan dalam menghadapi permasalahan mitra adalah metode edukatif yaitu melaksanakan pendekatan berupa sosialisasi, pelatihan dan pendampingan sebagai sarana transfer pengetahuan untuk pemberdayaan masyarakat. Hasil nyata dari pengabdian ini adalah pembangunan jalan pasangan batu yang berfungsi sebagai akses ke wisata air terjun Jurang Senggani. Senggani Gorge is one of the tourist attractions located in Nglurup hamlet, Sentang district, Tulungagung regency, is one of the mainstay attractions of Tulungagung City because of the charm of waterfalls and coffee plantations that are still natural because they are in the highlands. In addition to the natural beauty presented, there are obstacles, namely access, to reach the Senggani Gorge tourist attraction, access is still in the form of slippery clay soil and undulating contours due to the nature of clay, which is expansive. The purpose of this community service is to provide assistance related to the management of natural resources around the Senggani Gorge tourist area so that they are able to maximize the available natural resources, as well as provide knowledge related to the road structure work system with the masonry method. The method used in dealing with partner problems is the educational method, which is to carry out an approach in the form of socialization, training and mentoring as a means of knowledge transfer for community empowerment. The real result of this dedication is the construction of a masonry road that serves as access to the Senggani Gorge waterfall tour.

Abstract

Expansive clay soils undergo volumetric changes due to fluctuations in moisture content, which can cause structural damage to foundations, pavements, and embankments. Traditional stabilization methods, such as cement and lime, are effective but have a significant environmental impact, highlighting the need for more environmentally friendly alternatives. Lignosulfonate (LS), an organic stabilizer derived from industrial by-products, offers a more sustainable approach to improving soil strength and stability. This study evaluates the effect of 2% lignosulfonate on the unconfined compressive strength (UCS) of expansive clays. The research method involved mixing LS at 2% of the dry weight of the soil into the expansive clay (CL-ML) and conducting UCS tests on three untreated (control) samples and six treated samples. Statistical analysis was used to assess the significance of the differences between the two groups. Results show that the UCS increased from 236.29 kPa in the control group to 291.49 kPa in the treated group, reflecting a 23.37% improvement. Poisson's ratio decreased from 0.300 to 0.200, indicating reduced lateral deformation and enhanced soil stiffness, which improves the bearing capacity and stability of structures built on it. The UCS values ​​were observed to be consistent supported by low standard deviation. The study highlights the critical role of adequate sample replication and control over operational variables such as moisture content, compaction, and LS dispersion to ensure reliable and reproducible stabilization outcomes. This study strengthens the empirical basis for the application of LS as a sustainable and environmentally friendly stabilizer for expansive clays.

Abstract

Highways have an important role in the economic and tourism sectors, providing easy accessibility and accelerating regional growth. Senggani Gorge, a tourist attraction in Nglurup Hamlet, Sentang District, Tulungagung Regency, is the main attraction with the charm of waterfalls and natural coffee plantations in the highlands. However, accessibility constraints arise because the path to the tourist attraction is still slippery and bumpy clay. Clay soil conditions pose access difficulties, so more research is needed to understand the potential use of clay soil as a base layer of road pavement. This study focused on a research system that involved soil sampling on the access road to Senggani Gorge. Experimental methods were used to evaluate the effect of using clay subgrades on such tourist road access. The laboratory CBR test was conducted to test the strength of clay subgrade in road pavement construction, with the main aim to determine the impact of its use on tourist access to Senggani Gorge in Tulungagung. The results showed the percentage of CBR in collision variations 10, 25, and 56, as well as a comparison with research in Nglurup Hamlet which reached a CBR value of 27%. These findings are expected to provide a dimension of comparison and generalization of results, broadening understanding of the use of clay soils as road construction materials in various locations.
