Abstract

The construction of the inspection road located in the Brigif retention pond was directly crossed by the Krukut River. For safety and comfortable road traffic against sliding, it would need a redesign of the slope of road in order to produce a safety factor (SF) ≥ 1,25 for static condition and SF ≥ 1,10 for dynamic condition. Slope conditions are considered when High Water Level (HWL) and Low Water Level (LWL) conditions. This analysis was carried out by using of manually calculations and SLOPE/W. Both assessment using the Simplified Bishop Method. The results shows that when HWL in static conditions is 3,20 for manual calculations and 2,48 for SLOPE/W. Then, when HWL conditions with the dynamic condition is 1,88 for manual calculations and 1,72 for SLOPE/W. In LWL of static conditions is obtained of 3,13 for manual calculations and 2,58 for SLOPE/W. The results of the analysis of SF LWL with dynamic conditions is 2,20 for manual calculations and 1,79 for SLOPE/W. It can be concluded partially that the slope condition is stable. Furthermore, to prevent the scouring effect on retaining walls on the slopes is used gabion. Stability safety factor (SF) for overturning is 4,25 ≥ 2; for sliding is 1,59 ≥ 1,5; and for the bearing capacity is 825,31 kN/m ≥ 378 kN/m. Overall stability analysis is shown that the slope with the reinforced with gabion system is able to retain the overturning, sliding and bearing capacity.

Abstract

Jalan penghubung antara RW 03 Kelurahan Beji Timur dan RW 09 Kelurahan Pondok Cina, Kota Depok, masih merupakan jalan tanah sehingga jika musim hujan dapat menghambat akses masyarakat. Tujuan kegiatan Pengabdian kepada Masyarakat (PkM) ini adalah untuk meningkatkan jalan tersebut menjadi jalan beton dengan memanfaatkan limbah terak Submerged Arc Welding (SAW) sebagai substitusi material pada perkerasan kaku (beton). Sebelumnya, telah dilakukan penelitian pemanfaatan limbah terak SAW sebagai substitusi agregat kasar pada beton dan menunjukkan kinerja yang baik dalam meningkatkan kekuatan dan daya tahan beton. Mitra dalam kegiatan ini adalah masyarakat RW 03 Beji Timur, yang membutuhkan akses jalan yang lebih layak dan aman. Kegiatan ini melibatkan beberapa tahapan, yaitu survei lokasi, pengadaan material, pengecoran dengan beton ready mix, dan perawatan beton. Dampak kegiatan ini bagi masyarakat setempat sangat positif, yaitu mempermudah aksesibilitas, meningkatkan keselamatan pengguna jalan, dan mengurangi produksi limbah industri. Pemanfaatan limbah terak SAW ini tidak hanya berkontribusi terhadap pembangunan infrastruktur yang berkelanjutan tetapi juga memberikan solusi ramah lingkungan yang mendukung pengurangan emisi karbon. Selain itu, kegiatan ini juga membuka peluang untuk pengembangan lebih lanjut dalam penerapan limbah industri sebagai bahan konstruksi alternatif yang lebih ekonomis dan berkelanjutan. Dengan demikian, program PkM ini tidak hanya mendukung kesejahteraan masyarakat tetapi juga berperan dalam upaya pelestarian lingkungan.

Abstract

Slope stability is a crucial factor in land management, especially in the context of environmental protection and erosion control. Vetiver plants can increase the compressive and shear strength of soil. The purpose of this research is to analyze the effect of vetiver roots on soil cohesion and shear angle in the laboratory and to analyze the effect of vetiver roots on slope stability using Geostudio Slope/w software in 2024. The analysis method used is the bishop method. The results obtained based on laboratory testing state that vetiver roots that have an age of 5-6 months increase the cohesion value from 0.099 kg/cm2 to 0.240 kg/cm2. The cohesion value increased by 142% at a depth of 20 cm against a slope of 35.54°. Based on the slope stability analysis using Geostudio slope/w in 2024, the largest percentage increase in safety factor (SF) value was obtained at 4.98% with a distance between vetiver plants of 80 cm and 10.32% with a distance between vetiver plants of 30 cm. However, the subsequent increase in root length did not affect the safety factor (SF) value.

Abstract

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 public’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 public’s inability to buy masks and hand soap whose prices soar. The Jakarta State Polytechnic Civil Engineering Department’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.
