Abstract

Salah satu dari lokasi potensial pariwisata berada di Kabupaten Kepulauan Mentawai, yang termasuk wilayah provinsi Sumatera Barat dengan ibukota Tuapejat yang berada di Kecamatan Sipora Utara dan berjarak 153-kilometer dari Padang. Hal ini menjadi penyebab industri pariwisata di Mentawai masih jauh tertinggal akibat buruknya infrastruktur jalan dan jembatan serta pengelolaan lingkungan yang masih kurang tertata dengan baik termasuk kesiapan menghadapi bencana. Langkah strategis adalah dengan mengacu kepada pembangunan berwawasan lingkungan, kelestarian lingkungan dapat tetap terjaga disertai dengan meningkatkan ketahanan terhadap bencana. Tim PkM Prodi Teknik Sipil UKI berkolaborasi dengan pemerintah setempat dalam mendukung hal ini berupa bimbingan teknis dan pendampingan kepada Masyarakat dan Perngkat desa setempat di Kabupaten Kepulauan Mentawai untuk mempersiapkan desa wisata ramah lingkungan dan tanggap bencana. Tim Prodi Teknik sipil UKI menyediakan materi bimbingan teknis yang terkait dengan lingkungan berkelanjutan sesuai konsep desa wisata ramah lingkungan dan tanggap bencana melalui pemberdayaan masyarakat secara swadaya dan swadana.     Abstract: One of the possible tourism destinations is the Mentawai Islands Regency, located in the province of West Sumatra and has the capital city of Tuapejat in the Sipora Utara District, 153 kilometers from Padang. This is why the tourism business in Mentawai currently needs to catch up due to poor road and bridge infrastructure and poorly structured environmental management, particularly disaster preparedness. The strategic step is to refer to environmentally sound development to ensure ecological sustainability while strengthening resilience to calamities. The PkM UKI Civil Engineering Study Program team worked with the local government to prepare eco-friendly and disaster-responsive tourism villages in the Mentawai Islands Regency by providing technical guidance and assistance to local residents and village officials. Through self-help and self-funding community empowerment, the UKI Civil Engineering Study Program team delivers technical guidance material connected to a sustainable environment based on the notion of an eco-friendly and disaster-responsive tourism town.

Abstract

The earthquake that struck Cianjur Regency, West Java Province, on Monday, November 21, 2022, at 1.21 pm, killed 268 people and damaged or destroyed over 2,000 buildings (BMKG, 2022). The soil movement is generally in rock layers class C (hard soil) to layer D (medium soil), according to the geological map of building damage below. The Cugenang fault, which runs north 347°E and tilts 82.8° to the right perpendicular from Nagrak village to Ciherang village to the northeast in the Cianjur region, is the cause of severe building damage. Ground movements generally occur in rock layers C (hard soil) to D (medium soil). Because the earthquake's magnitude was not too large, the faults did not continue to the surface (surface rupture). However, they caused many aftershocks of lower intensity in the direction of Warungkondang to Karang Tengah for 12 km and a width of 8 km. The Rupture Area was the worst location for building damage. Even though the earthquake movement begins at the epicenter, the epicenter is not always the location of the most severe damage. The fault line of the earthquake source points to the West-South-West (WSW)-East Northeast (ENE) with the fault slope (dip) to the south and the fault direction to the left, according to data on the distribution of the epicenter of the earthquake. As a preventative measure, a technical review of the geological aspects of the Cianjur earthquake is required to ensure no casualties or material loss at the exact location if repeated earthquakes occur

Abstract

Gempa bumi merupakan salah satu bencana alam yang dahsyat yang sangat mengganggu aktivitas manusia. Secara geografis, Indonesia terletak di antara dua benua dan dua samudra. Seperti diketahui bersama bahwa Lempeng Indo-Australia, Lempeng Eurasia, dan Lempeng Pasifik semuanya melewati Indonesia. Potensi pergeseran kerak bumi inilah yang memicu terjadinya gempa saat terjadinya patahan atau patahan bergerak. Akibat gempa yang terjadi di Kabupaten Cianjur Provinsi Jawa Barat pada Senin 21 November 2022 jam 13.21 WIB telah mengakibatkan 268 korban jiwa dan lebih dari 2000 bangunan rusak parah bahkan hancur sama sekali berdasarkan data BMKG. Kegiatan pengabdian masyarakat ini merupakan kerjasama dengan beberapa instansi terkait untuk melakukan assessment kerusakan bangunan di daerah yang terdampak bencana gempa bumi. Lokasi yang di asses adalah desa Cikancana kampung Babakan Bandung Kabupaten Cianjur. Masalah utama adalah bahwa bangunan rumah dan bangunan fasilitas umum di lokasi ini belum memenuhi standar bangunan tahan gempa menurut peraturan terbaru SNI 1726:2019 khususnya pada sambungan sambungan.   Assessment of residential house damage after Cianjur Earthquake November 2022 Based on PUPERA Standard   Abstract: Earthquake is one of the most catastrophic natural catastrophes, significantly impacting human activity. Indonesia is situated physically between two continents and two oceans. As we all know, the Indo-Australian, Eurasian, and Pacific Plates travel through Indonesia. Earthquakes are caused by potential movement in the earth's crust caused by faults or fault movement. The earthquake that rocked Cianjur Regency in West Java Province on Monday, November 21, 2022, at 13.21 WIB killed 268 people and damaged or destroyed about 2,000 buildings, according to BMKG data. This community service activity is a collaboration with numerous associated entities to survey building damage in earthquake-affected communities. Cikancana Village, Babakan Village, Bandung, and Cianjur Regency were the locations evaluated. The fundamental issue is that this site's dwellings and public facility buildings must fulfill earthquake-resistant building standards based on the most recent SNI 1726: 2019 regulations, particularly for joints.

Abstract

Polypropylene fiber is made from chemical hydrocarbon compounds (C3H6) in single filaments or thin fibrous networks. Because the plastic fibers of polypropylene fiber mesh function as anti-cracking and reduce the brittle properties of concrete, a mixture of PFM and epoxy resin can increase the compressive strength and flexibility of concrete referred to ACI Committee 544. The polypropylene fiber additions used in this study were 0.60 kg/m3, 0.70 kg/m3, and 0.80 kg/m3, with an addition of 8% epoxy resin. Sixteen blocks (15 cm x 15 cm x 60 cm) with a design compressive strength of f'c 25MPa and a water-cement factor of 0.61. SNI 7656-2012 is referred to in the test standard. Compression and flexure tests were performed at 14 and 28 days of age. With the addition of 0.7 kg/m3 polypropylene fiber mesh, the compressive strength increased by 9.56% at 14 days of concrete age to 27.39 MPa. Meanwhile, at 28 days, it had risen by 20% or 30 MPa. Furthermore, for 14 days, the bending moment was 11943766.2 N.mm, and for 28 days, it was 13246692.5 N.mm.

Abstract

As an archipelagic country and agricultural land, coastal areas and agriculture dominate most of Indonesia's mainland. These conditions make oyster shells waste and rice husk ash very easy to obtain in large quantities as a component for making concrete. It can be an appropriate technological solution for manufacturing concrete with local wisdom. The research used 24 specimens in cylinders with a diameter of 15cm and a height of 30cm, referring to SNI 7656-2012 with a k-300 or 25 MPa concrete plan. The composition of 10% oyster-shells waste was used as a substitute for fine aggregate, while the composition of rice husk ash varied, namely 3%, 5%, and 7% as a substitute for cement. Concrete curing was carried out 14 and 28 days before the compression test. The compressive strength test results for regular concrete at 14 and 28 days, respectively, were 24.72 MPa and 25.00 MPa according to the design compressive strength. The compressive strength value of concrete with a mixture of rice straw ash and shellfish increased from regular concrete at 14 days of age, namely 25.95 MPa, 27.18 MPa, and 26.04 MPa for each variation of 3%, 5%, and 7 %. Whereas at 28 days of concrete age, using variations of shellfish waste mixture of 3%, 5%, and 7% obtained compressive strength of 27.18 MPa, 28.21 MPa, and 26.99 MPa. Thus, there is an increase in compressive strength ranging from 0.05% -0.12% in concrete using a mixture of oyster-shells waste and rice husk ash

Abstract

On Monday, November 21, 2022, a 5.6 SR earthquake hit Cianjur Regency, West Java Province. The earthquake damaged residential buildings and caused landslides in crucial, densely inhabited areas. The eastern plateau of Sarampad Village had a long land shift fault. In Sarampad Village, faults have caused physical ground shifts that have displaced the cottages in the fields far away. In the horseshoe area of the national road between Cianjur City and Puncak, landslides occurred with a steep slope on the upper slope of the highway and a slope on the side of the highway leading to the river below the road. Having a river means the water at the land's surface that the community and army dormitories use. The soil becomes water-saturated soil, making landslides easy in an earthquake. Stone gabions and terracing have strengthened landslides on the highway ridge. Meanwhile, roadway landslides are unreinforced. Other defects on road sections transversely on the road body near the Horseshoe with curved contours must be taken seriously

Abstract

The occurrence of earthquake disasters in Indonesia, attributed to its location within the Ring of Fire, consistently leads to human and material losses for the residents residing in the impacted areas. The seismic event on November 21, 2022, at Cianjur, resulted from tectonic activity along the Cugenang Cianjur fault and subsequent landslides near Sarampad Village, the horseshoe-shaped region. The seismic activity associated with an earthquake can induce landslides, amplifying their destructive potential and posing a severe threat to slopes already susceptible to instability. Still, landslides can occur for various reasons depending on the local soil and weather. Subsequently, a data collection process was undertaken to allocate governmental aid to the community to reconstruct their residences. The Cugenang fault area is characterized by its topographical features, including mountain slopes, hillsides, and river cliffs or valleys. Specifically, areas with slopes over 40% are classified as zone A. The identification of landslide-prone locations is conducted following established protocols such as Landslide Management Planning Procedures SNI 03-1962-1990, Field Engineering Geological Mapping Procedures SNI 03-2849-1992, and Procedures for Making Slope Maps SNI 03-3977-1995. If necessary, community mitigation actions can be implemented after identifying landslide danger or regions at risk. In the event of a landslide, communities employ several methods, including preparation, engineering, acceptance, and monitoring and warning systems. Planning control reduces risk; an engineering solution strategy reduces landslide probability or impact. Acceptance strategy accepts or unavoidable, and monitoring and warning system strategy reduces risk by evacuating before failure

Abstract

In tropical countries surrounded by water, coastal development initiatives are unavoidable. Because chloride compounds (Cl) in seawater are corrosive to concrete and interact directly with seawater, using concrete in coastal locations requires careful consideration—adding pozzolan-like glass powder to concrete results in minimal water absorption. Nylon fiber, on the other hand, is abrasion-resistant and can boost the flexural strength of concrete. In line with SNI 7656-2012, this study used fresh and sea water to maintain test specimens 15 cm wide, 15 cm long, and 60 cm high with a design f'c strength of 25 MPa at 14 and 28 days. The compressive strength increased by 27.9 MPa, and the flexural strength increased by 29.2 MPa after 14 days and 28 days of drying in clean water with 1% fiber variation, respectively. In seawater, the compressive strength at 14 days is 26.5 MPa, the flexural strength at 28 days is 28.8 MPa, and the flexural strength at 28 days is 2,773 MPa and 3,312 MPa. Concrete cured with sea water is lower than concrete treated with fresh water. On the other hand, adding polyamide/nylon to concrete containing glass powder can reduce compressive strength loss by up to 4%.

Abstract

Sumedang Regency in West Java Province experienced a 4.8M earthquake on Sunday, December 31, 2023. According to the Indonesian Meteorological, Climatological, and Geophysical Agency, the earthquake occurred 2 km northeast of Sumedang Regency, West Java, at 107.94E and 6.85S. At 5 km, the epicenter was shallow. Many residential structures were rendered unworkable, with slight to serious damage. The seismic consequences also reached Garut, Cirebon, and Bandung. Understanding the geological, geophysical, and geographical features of Sumedang is important because the zoning is disaster-prone. A thorough understanding of Sumedang's geology is needed to conduct ongoing studies on fault zones, land movement analysis, building risk assessment, infrastructure stability evaluations, and sustainable development initiatives, which will affect the area's infrastructure and settlements' resilience and stability.

Abstract

Buildings or structures in Indonesia are highly vulnerable to earthquakes, especially in seismic zone 5. Podium-type buildings consist of two main parts: the podium and the tower. This type of building is used due to its advantages of better stability, resulting from a wider base, efficient land use, and good seismic performance. Therefore, this study aims to analyze the structural behavior of three types of buildings: non-podium structures, centrically supported podium towers, and eccentrically supported podium towers. The analysis is conducted using the response spectrum analysis method to examine various structural behaviors, including comparisons of base shear forces, inter-story drift, and the P-Delta effect. The analysis results show that the base shear force of the non-podium structure is 18,463.26 kN, which is higher than that of the centrically supported podium tower at 10,661 kN and the eccentrically supported podium tower at 10,661 kN. In terms of inter-story drift in the x-direction, the eccentrically supported podium tower (model 3) has a displacement of 64.405 mm, exceeding the permissible limit of 61.538 mm. Meanwhile, the non-podium structure (model 1) has a displacement of 60.658 mm, and the centrically supported podium tower (model 2) has 56.408 mm, both meeting the permissible drift limits. For the maximum P-Delta values, Model 1 is 0.0964, Model 2 is 0.05844, and Model 3 is 0.0722, all of which comply with the P-Delta effect limits. The findings of this study are expected to provide a deeper understanding of the differences in structural performance between non-podium structures, centrically supported podium towers, and eccentrically supported podium towers, which can be used as a reference for designers in selecting a structurally safe system by increasing stability against lateral loads.
