Abstract

Bridges have a central role as routes that connect between regions, one of which is Permata Jangli Housing Phase 2. Because of the importance of this connectivity, community dedication to repairing bridges is a major concern in efforts to maintain the safety and sustainability of the bridge. This community service examines repair methods for the retaining walls around the bridge to avoid the potential for the bridge to be eroded by water flow. Through the active participation of community members and the implementation of appropriate construction techniques, the results of this collaboration show that the retaining walls around the bridge have been successfully repaired, as well as increasing their resistance to water pressure and erosion. The success of this community service not only improves the quality of life of local residents by ensuring sustainable connectivity, but also empowers communities in efforts to preserve their vital infrastructure. This community service can be an inspiring example for similar efforts in similar housing complexes that face similar challenges in maintaining important infrastructure such as bridges. This underlines the important role of community service in maintaining infrastructure as a key aspect in sustainable development in urban housing.

Abstract

Penelitian ini dilakukan untuk mengetahui perkuatan struktur kolom dan balok yang dibutuhkan pada bangunan Masjid Ash-Shohabat di Jl. Banjarsari Selatan, Tembalang, Semarang, karena perubahan pemanfaatan ruang.   Ada 2 kolom berukuran 25x40 cm dengan tinggi 350 cm yang akandihilangkan. Akibat penghilangan kolom ini perlu dilakukan kajian penelitian apakah perlu perkuatan pada kolom dan balok yang masih ada atau tidak. Setelah dilakukan analisis dengan software SAP2000, diperoleh hasil momen maksimal pada ujung - ujung balok 76,1 KNM yang mana ini melebihi momen kapasaitas balok sebesar 62 KNM, sehingga diperlukan perkuatan struktur. Metode perkuatan yang digunakan adalah dengan menggunakan material CFRP (Carbon Fiber Reinforced Polymer), dimana kekurangan tulangan yang diperlukan pada balok tersebut, diganti dengan material CRFP. Dari hasil perhitungan maka diperoleh kebutuhan CRFP sebanyak   2 buah dengan ukuran 220 mm x 1800 mm tebal 0,15 mm yang dipasang pada sisi atas ujung - ujung balok. Waktu yang dibutuhkan untuk pelaksanaan hanya 3 hari dengan biaya Rp3.800.000,-.

Abstract

2022 is the beginning of offline learning after the Covid-19 pandemic. where previously learning was carried out online including practicums. One of the practicums carried out in the Semarang State Polytechnic Civil Engineering department is the masonry practicum which is carried out for semester 1 students. With the offline masonry practicum, the practicum will leave behind brick fragments that can no longer be used. These broken bricks will usually be thrown away at the end of each semester after all the practicums have been carried out. the proportion of brick fragments to intact bricks usually reaches 30% to 40%. The construction workers come from the Ngadirgo community, they learn building work autodidactically based on experience. With the continued development of BSB, there are quite a lot of employment opportunities, including development workers. Techniques and methods of masonry work that comply with construction standards can increase the ability of craftsmen to become skilled workers so that it is hoped that they can improve the welfare of the community around Ngadirgo sub-district, Mijen sub-district. Ngadirgo sub-district currently has a village cemetery which is located in Ngadirgo hamlet RW 2, in this cemetery there is no coffin house which is used to store death equipment including the coffin which is currently still entrusted to one of the residents' house. With the existence of coffin house products made from brick masonry in the village cemetery area.

Abstract

Construction prioritizes the strength of concrete without thinking about the negative impact on the environment. The cement industry is estimated to contribute 5-7% of CO2 gas emissions in the world. On the other hand, Indonesia is also faced with environmental problems caused by various industrial waste. From this problem an innovation emerged, namely ABUTA (husk ash and brick ash). The aim of this innovation is to create a concrete innovation using Abuta Waste (Rice Husk Ash, and Brick Powder). For the manufacture of economical, environmentally friendly concrete to reduce the negative impacts caused by excessive use of cement and reduce industrial waste in Indonesia. In writing this proposal the author used the experimental writing method and data collection method. The concrete innovation applied is concrete with a mixture of variations in the composition of rice husk ash powder and red brick powder of 10% of the cement composition in conventional concrete so that it is more economical and environmentally friendly. In this study, the ACI (American Concrete Institute) mix design method was used with the required design quality of 30 MPa. It is hoped that this innovation can become an environmentally friendly concrete innovation to reduce the negative impacts of excessive cement use and reduce industrial waste in Indonesia. Based on the mix design, the proportion of ash mixture (rice husk ash and brick powder) is 1:1. Meanwhile, the ratio of the amount of ash mixture to cement is 10%: 90%. The compressive strength of concrete with a 0% Abuta mix variation (7 days old) was 19.5, while the concrete innovation with a 10% Abuta mix variation (7 days old) was 15.70 Mpa. This means that the 10% mixture reduces the compressive strength value by 46.28% below the 0% abuta mixture variation. Using a mixture of 10% ash (rice husk ash and brick powder) in innovative concrete can reduce production costs by IDR. 76,700/m ³. Based on the materials obtained in this manufacture, it can be concluded that to obtain optimal compressive strength, better quality materials are needed. The application of concrete can be applied in casting work floors and non-structural construction work such as buildings that require general load power such as housing, sculpture, home interiors and others.
