Columns are the most important element in a structure. Indonesian concrete regulations SNI 2847-2013 states that columns are elements that receive a minimum axial and bending loads of 0.1 Pu. Column damage can occur due to overloading damage, poor detailing in design, poor construction, etc. However, the most frequent damage is post-earthquake damage. The easiest reinforcement is the concrete jacketing method. The reinforcement material used in this research is bamboo. The test was done using the Quasi Static Loading Test method with lateral loads according to the displacement control and constant axial load. The results showed that the reinforcement by concrete jacketing from the initial dimensions of 15x15x90 cm to 21x21x90 cm showed the increase of lateral capacity, ductility, stiffness, and energy dissipation. In addition, it can be seen that the effect of reinforcement on both damaged and undamaged columns is less significant, which means that reinforcement can restore the initial capacity of existing test specimens to exceed 100%.

High-rise buildings in Indonesia must be designed resistance to receiving earthquakes. This is because the earthquake load that occurred in Indonesia has a high intensity. So that existing buildings, especially multi-story buildings must ensure good performance in receiving earthquake loads. This effort aims to maintain the safety of its users. Several aspects that need to be considered in designing earthquake-resistant buildings are structural performance and construction costs. Therefore, in this study, we will discuss the designed of earthquake-resistant structures by making comparisons on concrete structures and also steel structures which will then analyze the cost of the structure for the structures that have been analyzed and designed. From the results of the analysis, for the same conditions, earthquake resisting frame with reinforced concrete construction, it requires cheaper construction costs compared to steel construction. Concrete construction requires a structural cost of Rp. 19,030,188,114.0 and for a steel structure of Rp. 72,206,697,860.7. This is certainly not a conclusion that concrete construction is superior to steel construction. Because even though it is more expensive in terms of cost, steel construction is quite superior in terms of quality, time efficiency and ease of implementation.

The increasing demand for concrete as a construction material has resulted in the depletion of natural resources. This motivates the construction industry to continue to innovate in the manufacture of concrete. The utilization of iron ore waste as a substitute for fine aggregate is one of the solutions. This study aims to determine the optimum composition of iron ore waste as a substitute for fine aggregate on compressive test strength and economic value of concrete mix materials. This study used coarse aggregate from the quarry location of Mount Batu PTP Pelaihari District, Tanah Laut Regency, fine aggregate from the iron ore crushing plant location from the stockpile of Perusda Baratala and ex. Palangkaraya. The testing at the UPT Construction Material Testing Laboratory DPUPRP Tanah Laut Regency, South Kalimantan Province. The results showed that concrete using fine aggregate/sand ex. Palangkaraya has a concrete quality of K-235.94 kg/cm2 or fc'= 19.583 Mpa. As a result, it was found that the concrete mixes were more efficient than the concrete mixes used in the concrete batching plant, and that the concrete mixes were more efficient than the concrete mixes used in the concrete batching plant AK (Coarse aggregat) 54%: AH (fine aggregates) 45% has a concrete quality of K-257.29 kg/cm2 or fc'= 22.849 Mpa. This shows that iron ore waste fine aggregate can be used in concrete mixes

Abstract: In construction projects in the field during the construction process and after construction, we oftenencounter various problems, one of which is damage to the concrete which can result in weakening of thestructure. We can find this damage in concrete structural elements such as columns, beams, plates, concrete walls. Therefore, it is necessary to prevent this damage by conducting case studies regarding the causes of damage to concrete so that the causes of damage can be identified and minimized. This research was carried out in collaboration with the applicator and observations in the field to obtain relevant data. This data will be analyzed for the causes of damage by comparing it with experts' theories, then results will be obtained as to the general causes of concrete damage and suggestions for prevention that can be taken. Based on the research results, it was found that the factors that cause concrete damage are casting height,formwork removal errors, ironing errors, vibrators, curing, casting dilatation, design failure, and additional loads. Incorrect use of vibrators turns out to be the most dominant factor causing damage to concrete.

Kemampuan mitra didalam ketidakmampuan dalam melaksanakan kegiatan desain secara teknis pada bangunan gedung yang sesuai dengan peraturan konstruksi terbaru, mengharuskan adanya kolaborasi dengan pengabdi dari perguruan tinggi untuk bersama memecahkan masalah tersebut. Kegiatan ini memiliki dampak yang bagus kepada dua pihak, antara keilmuan perguruan tinggi dan juga mitra. Dalam kasus ini, pengabdi melakukan pendampingan dalam mendesain bangunan gedung ibadah Masjid pada SMK N 1 Gedangan. Perencanaan meliputi analisis/ desain struktur, perencanaan sistem drainase dilingkungan sekitar, dan perhitungan rencana anggaran biaya yang dibutuhkan. Pendampingan dilaksanakan selama 8 bulan dimulai dari tahap survey, tahap diskusi, tahap anaisis, dan tahap pemaparan hasil. Struktur yang diguanakan adalah beton bertulang pada bagian portal gedung dan menggunakan atap baja sebagai struktur penutup atap. Adapun kebutuhan biaya total sesuai dengan AHSP dan SHBJ terbaru adalah sebesar Rp. 2.847.670.754,14.

Desa Ganjaran yang berada di Kecamatan Gondanglegi, Kabupaten Malang, berpotensi menghadapi masalah penurunan kapasitas penyimpanan air tanah akibat alih fungsi lahan. Berdasarkan permasalahan tersebut dilaksanakan pengabdian masyarakat ini, dengan tujuan untuk mengupayakan konservasi air tanah. Dimana pada pelaksanaan dilakukan dengan cara pendampingan ke masyarakat melalui penerapan biopori dan sumur resapan. Cara ini dipilih karena mudah diterapkan, berbiaya rendah, dan efektif meningkatkan infiltrasi air ke dalam tanah. Program ini dilaksanakan dalam dua tahap: persiapan dan pelaksanaan. Pada tahap persiapan, dilakukan perumusan kerangka kerja, identifikasi pemangku kepentingan, serta survei dan pengumpulan data lapangan. Tahap pelaksanaan mencakup sosialisasi dan edukasi masyarakat, pengadaan prototipe biopori dan biopori jumbo, serta pelatihan teknis. Partisipasi aktif masyarakat sangat diutamakan untuk membangun rasa kepemilikan dan pemahaman yang mendalam mengenai konservasi air. Hasil kegiatan menunjukkan peningkatan pemahaman dan partisipasi masyarakat dalam upaya konservasi air. Prototipe biopori yang terbuat dari pipa PVC dan biopori jumbo dari kaleng cat besar berhasil diterapkan oleh warga, mendorong mereka untuk mengadopsi metode ini secara luas. Dampak positif dari program ini tercermin dalam meningkatnya jumlah sumur resapan dan biopori di desa, serta pengakuan Desa Ganjaran sebagai Desa Berseri tingkat Pratama di Kabupaten Malang.
