Abstract

Road pavement construction requires standard planning and evaluation of the foundation layer's structural strength. The commonly used standard is the California Bearing Ratio (CBR). In situ, road layer CBR value evaluation mainly uses a Dynamic Cone Penetrometer (DCP), Sand Cone, or direct CBR. Using these tools requires a lot of equipment, time, and human resources; therefore, more efficient and practical in situ tests such as Light Weight Deflectometer (LWD) are needed. This research was conducted to find any correlation between the results of the LWD test and the results of Field CBR and DCP testing on pavement road's base course. Data collection was carried out at River Side and Rich Village residential areas. From this research, it can be concluded that there is a significant correlation between the LWD modulus value and the 600 mm CBR DCP and the max CBR DCP conversion modulus, with an average coefficient of correlation 0.96 and 0.958. ABSTRAK Pekerjaan konstruksi perkerasan jalan raya membutuhkan standar dalam perencanaan dan evaluasi kekuatan struktural lapisan pondasinya. Standar yang digunakan yakni nilai California Bearing Ratio (CBR). Evaluasi nilai CBR di lapangan sebagian besar dilakukan menggunakan alat Dynamic Cone Penetrometer (DCP), Sand Cone, atau CBR langsung. Penggunaan beberapa alat ini membutuhkan peralatan, waktu, dan sumber daya manusia yang tidak sedikit, oleh karena itu diperlukan pengukuran lapangan yang lebih efisien dan praktis seperti Light Weight Deflectometer (LWD). Penelitian ini dilakukan untuk melihat bagaimana korelasi hasil pengujian alat LWD pada base course perkerasan jalan dengan pengujian CBR Lapangan dan DCP. Pengambilan data dilakukan di dua tempat yaitu perumahan River Side Bondowoso dan perumahan Rich Village Jember menggunakan ketiga alat. Hasil penelitian menunjukkan bahwa Terdapat korelasi sangat kuat antara nilai modulus LWD uji dengan modulus konversi CBR DCP max dan CBR DCP kedalaman 600 mm. Dengan rerata nilai korelasi berurut 0.958 dan 0.96.

Abstract

The construction of the Sepanjang-Mojokerto railway double track is an initiative to address the growing demand for railway transportation infrastructure. During the building of the double-track railroad, it is anticipated that the rail structure will endure the weight of traversing trains; hence, a stability study for settlement and sliding is essential. The settlement of the embankment between KM 49+500 and KM 49+750 was studied using sondir and borlog correlation data and then a geoslope model to see how stable the embankment was against sliding. The calculated findings indicate a reduction of 0.49 m to 1.49 m. The decrease is unsafe as it is above the permissible limit of 20 cm; achieving a decline to U90% requires around 0.9 years—15 years. Consequently, it is imperative to expedite the reduction using PVD and preloading. The PVD installation employs a triangle configuration with a spacing of 1.5 meters, requiring a duration of 16 to 20 weeks to achieve a 90% reduction. The stability control of the embankment against sliding on the railroad body yielded a safety factor (SF) value ranging from 1.63 to 2.33. SF > 1.5 indicates that the SF value is secure, surpassing the permissible threshold.

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

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

Embankment material in dam construction is an important aspect that needs to be considered. The lack of embankment material around the dam is a problem in the Meninting Dam construction project, so it uses materials outside the dam area. With the change in the embankment material used, research is needed on the stability of the dam body. This study aims to determine the characteristics of the replacement material, seepage capacity, uplift force, and slope stability safety factor at the dam. Physical tests are used to determine the physical characteristics of the soil (moisture content, soil specific gravity, rock specific gravity, soil plasticity index filter analysis), while the mechanical test is performed to determine the soil's movement, strength, stiffness, and deformation. This study also uses software assistance, such as Geostudio from Rockscience slide, to calculate a slope's stability level. The results showed that the value of the safety factor obtained on the upstream slope without earthquake is 3.463, the upstream slope with OBE earthquake is 2.057, the upstream slope with MDE earthquake is1.588, the downstream slope without earthquake is 3.117, the downstream slope with OBE earthquake is 2.288, downstream slope with MDE earthquake is 1.898. The value of the safety factor is declared safe because the value obtained is >1.5 conditions without an earthquake and >1.2 conditions with an earthquake. The uplift value on every equipotential is 10.58 t/m2. The value of seepage capacity that comes out downstream of the dam is 4,529 x 10-5 m3- seconds. Seepage capacity is said to be safe because < 0.0127 m3- seconds. The lack of stone material as the main constituent of dam deposits in the research area is the main factor in this study, which focuses on finding the value of the safety factor, lifting force, and seepage capacity of the replacement material for dam deposits. This research will use soil-filling material as a substitute for the Constituent stones, which are very limited in number at the research site.

Abstract

The construction of Double Track Sepanjang-Mojokerto KM 48 + 800 to KM.48 + 950 passes through an area with soft and compressible subgrade soil known from field testing data. After analyzing and calculating the settlement value, high settlement value is obtained for a long period. Efforts to solve the settlement problem in this study are to accelerate the settlement time using the Prefabricated Vertical Drain combined with Preloading. The use of this method aims to accelerate the process of settlement in the soil and increase the value of the soil shear strength (Cu) so that the subgrade becomes more stable also utilizes the pressure from the embankment, which also functions as a load (surcharge) that has been adjusted to traffic and construction loads. PVDs were installed with different patterns and spacing variations in order to calculate the efficiency of installation. Based on consideration of the number and time of PVDs to achieve 90% consolidation, a rectangular installation pattern with a spacing of 1.5 meters was selected, which was installed as thick as compressible soil layer at each point. The PVD calculation used settlement data obtained from the sum of consolidation settlement (SC) and immediate settlement (SI) from variations in the height of the embankment depicted in graphical form, which resulted in a polynomial equation. From this equation, the backfill requirement used to achieve the planned elevation of the embankment after the subgrade was installed with PVDs was obtained. Subgrade backfilling was carried out with a planned embankment height of 9-10 meters. The calculation was continued to find the increase in Cu of the subgrade and then analyzed for stability using the Geoslope program. The results of the final stability analysis after the soil improvement method at the point under review ranged from 1.8 to 1.98 and it was safe.

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.
