Abstract

Bendungan adalah bangunan yang terdiri dari urugan tanah atau batuan. Bangunan ini berfungsi untuk menahan laju air dari waduk atau danau, sebagai pembangkit listrik serta tempat rekreasi masyarakat. Bendungan Jragung terletak di desa Candirejo, Kecamatan Pringapus, Kabupaten Semarang. Dalam pembangunan bendungan ini diperlukan suatu bangunan pengelak yang berfungsi untuk mengelakan air sungai pada saat mengerjakan konstruksi bendungan utama. Pada pelaksanaan terowongan pengelak membutuhkan analisis klasifikasi batuan serta litologi batuan di lapangan dengan menggunakan metode Rock Mass Rating (RMR) dari Bieniawski 1989 untuk mengetahui kondisi litologi batuan beserta klasifikasinya. Selain itu digunakan metode Rock Mass Quality (Q)-System sebagai pembanding. Berdasarkan hasil analisis yang membandingkan dua metode menghasilkan batuan yang memiliki klasifikasi massa batuan fair rock yang termasuk dalam kategori III dengan nilai RMR antara 41- 60 dengan stand up time ± 24 jam sampai dengan ± 28 jam dan good rock yang termasuk dalam kategori II dengan nilai RMR 60-80 dengan rekomendasi pemasangan steel ribs dengan jarak 1,5 m pada metode RMR. Sedangkan pada metode Q-System menghasilkan klasifikasi massa batuan fair rock dengan panjang rockbolt pada penyangga terowongan 3 m serta ketebalan shotcrete 40-100 m tanpa tulangan dengan jarak rockbolt yaitu 2 m-2,3 m.

Abstract

Wood is widely used in construction due to its renewability and favorable mechanical properties; however, it is highly susceptible to fungal degradation, which reduces durability and structural performance. Conventional wood preservatives are effective but often raise environmental and health concerns because of their toxic chemical content. This study investigates the use of nano-urea as an eco-friendly wood preservative for sengon wood (Falcataria moluccana), representing one of the first studies exploring nano-urea specifically for antifungal wood protection and durability enhancement. Sengon wood samples were treated with nano-urea at concentrations of 2%, 3%, and 5%, alongside untreated control samples. Antifungal performance was evaluated through weight loss measurements, fungal growth observations, and assessment of the infected area after 12 weeks of exposure, while mechanical performance was assessed using tensile strength testing and microstructural analysis. The results demonstrated that increasing nano-urea concentration significantly reduced fungal degradation, with the 5% treatment completely inhibiting visible fungal growth. In addition, nano-urea treatment slightly improved tensile performance and produced a denser wood microstructure with reduced pore size, indicating enhanced structural compactness. These findings confirm that nano-urea is a promising sustainable alternative to conventional preservatives, offering effective biological protection while maintaining mechanical integrity. The proposed treatment also shows strong potential for scalable and environmentally responsible applications in sustainable construction and wood-based material industries.

Abstract

Rigid pavement with nailed-slab system is a replacement for the use of concrete claws with short posts. This study aims to design a prototype of rigid pavement with a nailed-slab system to be applied to soft soil in Demak. Soft soil samples were taken from Guntur, Demak by digging the soil surface ±50 cm. The prototype design began with the manufacture of a test tub measuring 200 x 200 x 150 cm with walls of thin steel plates on the back and sides. The base of the test body is made of thin steel plate and the front of the body is made of glass. At the bottom of the thin steel plate wall there is a water pipe that is used as an outlet water channel. The soil in the test tub that has been in accordance with the density in the field will be cut, so that the elevation is the same as the top of the test tub before the prototype of the pavement plate is placed on it. The prototype schematic of the test piece consists of reinforced concrete with a slab dimension of 120 cm x 120 cm x 10 cm, and a pole as an anchor with a depth of 100 cm and a diameter of 10 cm. Before casting on reinforced concrete, a strain gauge is installed that is tied to the prototype reinforcement, then cast and left for 28 days to make the concrete 100% perfect strength. After that, a loading test was carried out with a monotonic load in the form of a beam measuring 20 cm x 20 cm gradually with an increase in load twice from the previous load. The load is given from 1 kN, 2 kN, and 4 kN, the results show that the greater the load given, the greater the deflection produced.

Abstract

Abstrak Longsor merupakan suatu proses perpindahan massa batuan atau tanah akibat pengaruh gravitasi sebagai respon terhadap aktivitas alam yang menyebabkan kerusakan morfologi permukaan lereng, dan longsor yang terjadi di Wonogiri kemungkinan karena pelapukan lapisan batuan akibat curah hujan yang sering terjadi di aera tersebut. Penelitian ini dilakukan dengan tahapan pengambilan sampel batuan, pengukuran dan pengumpulan data sekunder. Klasifikasi batuan menggunakan parameter RQD, RMR dan Q-system untuk mengetahui karakteristik batuan. Hasil dari klasifikasi tersebut menunjukkan bahwa lapisan batuan di lokasi longsor masuk dalam kategori sedang hingga sangat rentan mengalami pelapukan. Dengan mempertimbangkan siklus curah hujan dan jumlah hujan dalam hari yang dihitung dalam satu tahun diketahui ada pengurangan kekuatan batuan berdasarkan penelitian terdahulu. Hasil analisa metode element hingga menunjukkan terjadi pengurangan kekuatan batuan berdasarkan parameter geser yang berakibat pada stablititas lereng batuan tersebut, dan pada tahun ke-10 diindikasikan nilai Safety Factor (SF) <1,3. Kata kunci: Kuat geser, siklus basah-kering, batuan  Abstract Landslide is a process of mass transfer of rock or soil due to the influence of gravity in response to natural activities that cause damage to the surface morphology of the slopes, and the landslide that occurred in Wonogiri was probably due to weathering of rock layers due to frequent rainfall in the area. This research was conducted with the stages of taking rock samples, measuring and collecting secondary data. Rock classification uses RQD, RMR and Q-system parameters to determine rock characteristics. The results of the classification indicate that the rock layers at the landslide location are in the moderate to very vulnerable category to weathering. By considering the rainfall cycle and the amount of rain in days calculated in one year, it is known that there is a reduction in rock strength based on previous research. The results of the finite element method analysis showed that there was a reduction in rock strength based on shear parameters which resulted in the stability of the rock slopes, and 10th year indicated the value of Safety Factor (SF) <1.3. Keywords: Landslide, wet-dry cycle, rock

Abstract

Gunungpati District is characterized by geomorphological conditions dominated by hilly terrain with moderate to steep slopes. These topographic features, combined with the local geological and hydrological conditions, increase the area's susceptibility to landslides. This Community Service Program (PKM) aimed to enhance community knowledge and preparedness regarding potential landslide hazards in Gunungpati District through a community-based awareness and education program. The program employed educational lectures, interactive discussions, and the distribution of educational materials to residents. The activities were held at the village hall and involved 30 participants from several villages in Gunungpati District. The results demonstrated a significant improvement in participants' understanding of the primary causes of landslides, early warning indicators, and appropriate mitigation measures that can be implemented at the community level. The participants' average knowledge score increased by 52%, rising from 33.75% before the program to 85.75% after its completion. These findings indicate that integrating public awareness sessions with interactive discussions, case study presentations, and visual learning media effectively enhances community understanding of landslide hazards and corresponding mitigation strategies. Consequently, this program provides a practical foundation for strengthening community resilience to landslide disasters in Gunungpati District.
