COVID-19 in Indonesia was first discovered in Depok, West Java. Two Depok Residents were declared positive COVID-19 on March 2, 2020. Since the announcement of the first case. Depok is now a city in West Java Province with the most COVID-19 positive cases. To suppress the spread of COVID-19, the Depok city government imposed large-scale social restrictions (PSBB) on April 15, 2020. The publicâ€™s impact is strongly felt due to the enactment of PSBB in terms of the economy. Many people have to lose their jobs. Public awareness in maintaining cleanliness and health is also still lacking due to the publicâ€™s inability to buy masks and hand soap whose prices soar. The Jakarta State Polytechnic Civil Engineering Departmentâ€™s Road and Bridge Design Engineering Program (TPJJ) is motivated to participate in assisting communities affected by COVID-19 by holding community service activities. Sukmajaya sub-district is the area in Depok that is most infected with COVID-19. Based on this, TPJJ Study Program will assist in providing public sinks, the distribution of masks, hand soap, and food at RT 009 RW 016 Bakti Jaya subdistrict Sukmajaya Sub-District, Depok. It is hoped that this activity can reduce the spread of COVID-19 and can ease the burden on people who are experiencing economic hardship.Â

Soft clay has a low bearing capacity, high compressibility and low permeability. This condition causes soft clay soil to have a long settlement time. To overcome this soft soil condition, soil improvement methods are needed. One of the efforts is to use a combination of soil preloading methods, Prefabricated Vertical Drain (PVD), and Prefabricated Horizontal Drain (PHD) methods. Calculating soil settlement with soil improvement is carried out using the Asaoka method, which is a field observation method, and the theoretical method using the Terzaghi method. Based on the calculation results of field observations using the Asaoka method, the average degree of soil settlement is 93.5%. The calculation results of the Asaoka method are recalculated using a back calculation to produce a new parameter value, namely the horizontal consolidation (Ch) value, which is then compared with the Ch value in the previous plan. In the Terzaghi method, the average soil settlement value is 1.205 meters. The results of soil settlement value are used to analyze the height of the embankment based on the load ratio requirement in SNI 8460: 2017, where the load ratio on the ground is ≥ 1.3 times the planned load under service conditions. Based on the monitoring results, a load ratio value of 0.875 was obtained so that the SNI requirements carried out a re-planning of the landfill. Then, proceed with the design of PVD and PHD. The results obtained in planning use triangular PVD patterns with a distance between PVDs of 1 meter.

The liquefaction simulator tool uses a one-axis shaking table model to determine soil features and behaviour that indicate liquefaction. This helps in implementing measures to mitigate its effects. The research system incorporates a frequency regulation system to control the speed of the 3-phase motor and a measurement system that monitors various variables associated with liquefaction. The variables include displacement, rocking table motion, acceleration, vibration frequency, and pore water pressure. This study used LabVIEW for frequency adjustment, data acquisition, processing, and presentation. LabVIEW improved the observations' accuracy using the linear regression method and descriptive statistical analysis at the data processing stage. The error value for the frequency adjustment without load was 1.65%, which increased to 8.75% when a load was applied. This study achieved a displacement measurement accuracy of 99.03% and an average pore water pressure measurement accuracy of 95.69%. The measurement accuracy of the accelerometer and accelerometer vibration frequency reached 66.98%.

The project seeks to promote the National Economic Development (PEN), specifically targeting the enhancement and advancement of economic activities on Sumatra Island. One of the current projects is the construction of the Sicincin - Padang Toll Road Section (STA 0+000 - 36+600) of the Pekanbaru - Padang Toll Road. This segment of the highway is a component of the Trans Sumatra highway network on Sumatra Island. The bearing capacity and settlement design of the spun pile foundation at the pile slab STA 7+443 - STA 7+569 Sicincin - Padang Toll Road were recalculated based on soil investigation data derived from SPT (Standard Penetration Test) results, subsequently compared with the findings from the PDA Test (Pile Driving Analyzer) conducted in the field. Soft soil issues were identified at STA 7 + 443, leading to the formation of fissures and landslides. The issues arose from the interaction between a pile foundation plate and the capacity of a revolving pile foundation. The objective of the study is to determine the bearing capacity and settlement of the rotating pile foundation at STA 7 + 443 - STA 7 + 569 using Standard Penetration Test (SPT) results and to compare these findings with the field data obtained from the Pile Driving Analyzer (PDA) test. The analysis conducted involved the adjustment of the N-SPT value utilizing tables and graphs in compliance with SNI 1725-2016, SNI 8460-2017, and SNI 4153-2008. The settlement assessment reveals the most significant discrepancy in the Meyerhoff Method compared to the PDA Test, amounting to 5.32%. The pile's settlement is within the allowable limit of 60 mm; hence it is deemed safe.

The existence of the Bawen-Salatiga toll road has caused an increase in the volume of vehicles on the Tingkir Road section, Salatiga City. In the first year of the opening of the toll gate, the maximum volume of vehicles per day was 23,937, while in the second year there were 26,203 vehicles passing through per day. This number continues to experience a significant increase over time. In order to reduce the potential for traffic congestion, PT Trans Marga Central Java plans to widen the road section. This study aims to determine the thickness of the pavement and the cost that will be used in the Jalan Tingkir widening project, Salatiga City. The pavement thickness calculation employs the 2017 road pavement design manual method (MDP) and utilizes Kenpave software for structural analysis. The second edition of the Central Java Province Construction Work Unit Price (HSP) for clan buildings is used as a reference for determining the cost of pavement work. Based on the results of the analysis, the thickness of the pavement layer was obtained: 40 cm for the AC-WC layer, 60 cm for the AC-BC layer, 80 cm for the AC base layer, and 30 cm for the class A foundation layer with a planned traffic load of 3.85 x 10⁶. ESAL. As for the strength value tested with Kenpave software, the repetition value of fatigue crack load (Nf) was 3.70 x 1012, the repetition value of groove crack load (Nd) was 4.41 x 106, and the repetition value of permanent deformation load was 3.19 x 1011. Based on the analysis of the cost budget plan, the cost for the pavement work was Rp9,019,773,857.81. The flexible pavement with a thickness of 48 cm can withstand the weight of fatigue cracking, groove cracking, and permanent deformation.

The construction of the Serang–Panimbang Toll Road Section III Phase 2 Package 3 was part of a National Strategic Project requiring a strong foundation to overcome soil settlement. Spun piles were used as the primary foundation to resist both vertical and horizontal loads. This study aimed to determine axial bearing capacity based on pile driving (calendering) and SPT data analysis, calculate lateral bearing capacity, and evaluate pile settlement and displacement. Pile driving analysis showed varying capacities, with the lowest value from the Navy-McKay formula (371.782 kN) and the highest from the WIKA formula (926.061 kN). The Meyerhof α formula from SPT analysis produced the highest axial capacity (1052.162 kN). Lateral bearing capacity based on Broms (1965) exceeded allowable limits in both sand (9608.429 kN) and clay (6272.101 kN). Pile settlement occurred as a response to structural loads acting on the foundation and was influenced by the physical and mechanical properties of the supporting soil beneath. Based on elastic analysis using Vesic’s method (1967), the maximum settlement was (25.224 mm), occurring at the interaction zone between the spun pile and dominant soil layers at foundation depth. This value remained within the safe limit according to SNI 8460:2017. Overall, the spun pile foundation proved effective in maintaining stability under vertical and horizontal force while ensuring structural integrity and sustainability against potential settlement and displacement.
