Abstract

Mount Semeru as one of the highest mountains on the Java island has significant volcanic activity to date. The eruption of this volcano had a considerable impact on the surrounding area, including Sumberwuluh Village, Candipuro District, Lumajang Regency. The impact felt by the community is not only physical damage but also trauma. Therefore, a disaster awareness culture needs to be built and strengthened early in order to reduce the impact caused when a disaster occurs. The Institute for Research and Community Service (LP2M) of the University of Jember in collaboration with the Regional Disaster Management Agency (BPBD) of Lumajang Regency carried out service activities for elementary school students and teachers in Sumberwuluh Village with the aim of strengthening the culture of disaster awareness. This activity has been attended by students and teachers from SDN Sumberwuluh 1, SDN Sumberwuluh 2, SDN Sumberwuluh 3, SDN Sumberwuluh 4, SDN Sumberwuluh 5 and MI Miftahul Ulum. This is carried out through two stages, socialization about the importance of disaster preparedness and direct practice of disaster preparedness consisting of water boat evacuation, webbing and trauma healing. This program has succeeded in increasing disaster preparedness awareness through disaster education from an early age. In addition, this activity also succeeded in improving knowledge and practical skills in disaster preparedness by 88% and building a better mentality and readiness in dealing with emergency situations.

Abstract

The Semajid River Basin (DAS) faces complex environmental problems, including flooding during the rainy season, drought during the dry season, increased river sedimentation, and uncontrolled land use changes. This study aims to assess the performance of the Semajid Watershed in accordance with the Minister of Forestry Regulation Number 61 of 2014 on Monitoring and Evaluation of Watershed Performance, and to formulate strategies to improve watershed performance through land-cover optimization scenarios. The watershed performance assessment includes criteria for land, water management, socio-economics, building investment value, and space utilization. The evaluation results show that the Semajid Watershed performance value is 113.75, which indicates that the watershed is in the category of needing to be saved. The application of the additional land cover scenario has a significant impact on improving the criteria for vegetation cover and protected areas. The Percentage of Permanent Vegetation Cover (PPV) increased from 5.5% (very high recovery category) to 32.44% (low recovery category), while the value of the protected area criteria decreased from 68.64 to 9.37, indicating an improvement in the ecological condition of the watershed. Although the watershed's carrying capacity increased to 107.5, the Semajid watershed remains in need of restoration. Therefore, restoration of the Semajid watershed requires integrated management that sustainably integrates technical and non-technical efforts.

Abstract

A reinforced concrete type retaining wall was built in 2017 to strengthen the slope stability of Rembangan highway, Jember Regency, Indonesia. However, in 2018 the building was damage. Until now, the cause of the failure of the retaining wall is still unknown. This study aims to evaluate the causes of the failure of retaining walls and the stability of retaining walls on the slopes of the Rembangan highway, Jember Regency. The research methodology begins with primary and secondary data collection before processing the data using conventional methods and auxiliary software. After data processing, data analysis was carried out to find conclusions about the cause of the failure of the retaining wall. Result analysis showed that the retaining walls have a low level of safety factor for rolling stability, shear stability, and bearing capacity stability. In addition, the factor of safety for the bearing capacity of the group pile foundation as a reinforcement of retaining walls also shows a smaller value than that charged. In addition, the group pile foundation can suffer a total settlement of 1.28 m.

Abstract

Kejadian longsoran yang dipengaruhi hujan sering terjadi di Indonesia. Hujan dipahami sebagai faktor yang dapat mempengaruhi peningkatan tekanan air pori dan kenaikan muka air tanah. Penelitian ini menggunakan data pengeboran, sifat mekanik, data curah hujan harian, kondisi hidrogeologi, dan data gempa. Longsoran yang terjadi merupakan longsoran dangkal, dengan kedalaman bidang gelincir 3 meter dibagian atas lereng dan 7 meter dibagian bawah lereng. Bidang gelincir longsoran memiliki bentuk rotasional. Material penyusun longsoran terdiri dari tanah dan batuan yang berasal dari pelapukan batuan vulkanik. Penampang bawah permukaan menunjukkan bahwa terdapat kontak antara breksi tufan lapuk sedang dan breksi tufan lapuk tinggi yang berperan sebagai bidang gelincir. Geologi lereng tersusun dari lava andesit-basaltik, breksi tufan lapuk sedang dan breksi tufan lapuk tinggi. Longsoran dangkal terjadi setelah dipengaruhi hujan hari-hari sebelumnya yang mempengaruhi peningkatan tekanan air pori. Proses terjadinya longsoran diawali dengan munculnya rekahan tarik. Hasil analisis menunjukkan pengaruh curah hujan tinggi secara drastis mempengaruhi penurunan matric suction pada lereng yang menyebabkan terbentuknya rekahan tarik. Pemodelan dilakukan dengan dua simulasi yaitu simulasi dengan pengaruh hujan pendahuluan durasi 47 hari dan pengaruh hujan durasi 10 hari dengan kondisi awal sama. Hasil analisis menunjukkan hujan pendahuluan 47 hari mempengaruhi terjadinya longsoran dibandingkan dengan curah hujan pendahuluan selama 10 hari. Hasil pemodelan durasi 10 hari memiliki nilai faktor keamanan yang lebih tinggi, menunjukkan tidak sesuai keadaan di lapangan karena mengabaikan kondisi hidrogeologi hari sebelumnya. Mekanisme terjadinya longsoran pada area penelitian dipengaruhi oleh tekanan air pori, rekahan tarik dan gempa bumi sehingga didapatkan faktor keamanan sebesar 0.986.

Abstract

Fenomena longsor merupakan bencana geoteknik yang sering terjadi di daerah tropis, termasuk Indonesia. Salah satu kejadian longsor yang terjadi pada Jalan Raya Gumitir KM 233+550 pada Juli 2023 mengancam kestabilan lereng yang vital bagi infrastruktur transportasi. Penelitian ini bertujuan untuk menganalisis stabilitas lereng pasca longsor dan membandingkan efektivitas metode perkuatan soil nailing dan gabion. Metode yang digunakan dalam penelitian ini adalah analisis stabilitas lereng menggunakan perangkat lunak geoteknik berbasis Limit Equlibrium Method, dengan data sekunder berupa data boring dan Standard Penetration Test. Hasil analisis menunjukkan bahwa lereng pada kondisi eksisting memiliki faktor keamanan 0,944, yang menandakan kondisi kritis. Setelah perkuatan dengan soil nailing, faktor keamanan global meningkat menjadi 1,917, menunjukkan bahwa lereng berada dalam kondisi aman. Sementara itu, perkuatan gabion menghasilkan faktor keamanan 1,562, yang masih memenuhi kriteria aman meskipun lebih rendah dibandingkan soil nailing. Berdasarkan hasil analisa, dapat disimpulkan bahwa kedua metode perkuatan efektif, namun soil nailing lebih direkomendasikan untuk meningkatkan kestabilan lereng pada lokasi vital dengan risiko longsor tinggi. Penelitian ini memberikan rekomendasi teknis untuk memilih metode perkuatan yang sesuai dengan kondisi lapangan dan tingkat risiko, dengan mempertimbangkan faktor keamanan, efisiensi, dan keberlanjutan.

Abstract

The Tegal Siwalan-Banyuanyar Highway in Probolinggo Regency has been damaged at several points and has not received any maintenance for the last 7 years. This has a huge impact on road users because it can interfere with driving comfort and safety, so it is necessary to analyze the road damage that has occurred, including the type of damage and an assessment of road conditions. The Bina Marga method and a light-weight deflectometer (LWD) can be used to assess road deflection in order to assess road condition. The results of this study obtained priority order values for each segment that were in the range 5-11. The greater the value of the Order of Priority obtained, the better the road condition, whereas the smaller the value of the Order of Priority obtained, the worse the road condition. It was also found that the Bina Marga method and the Light Weight Deflectometer (LWD) tool had a poor correlation, so a comparison between the two could not be made for assessing the condition of the road surface layer.

Abstract

Roads built on soft clay soils will experience damage before the service life is complete. One of the most common damages is potholes. The cyclic load is the repetitive load caused by the wheels of a vehicle. Stabilization of the subgrade needs to be done to overcome this problem, namely by adding lime. The lime used is quicklime from Sampang, Madura. The research was conducted to obtain the optimum lime mixture in the soil. CBR test was conducted on the soil with 3%, 5%, and 7% lime mixture. After that, cyclic loading was applied to analyze its effect on the CBR value. The original soil had a CBR value of 11.36% which then decreased to 5.79% after cyclic loading. The CBR values of 3%, 5%, and 7% lime-stabilized soil were 31.96%, 35.22%, and 34.48%, respectively. The optimum lime mixture in this study is 7% with a CBR value of 34.48% and a decrease in CBR value due to cyclic loading to 30.74%. Stabilization with lime can increase the CBR value up to 5% lime mixture. The addition of excess lime will reduce the CBR value. In addition, the decrease in CBR value due to cyclic loading decreases with the addition of lime. This is because the absorption and flocculation reactions by lime cause changes in the distribution of soil grain gradation.
