Abstract

Steel plate shear wall (SPSW) is one kind of steel earthquake resistant building structural stiffener that can dissipate the tremendous amount of quake energy, where the steel plate itself had been developed from years, and still in development. Ideally, SPSW is designed so all of its parts can absorb the energy of lateral force, seismic load for instance, through inelastic deformation. Because of that, the thickness of applied steel plate in a section of a building (a portal in this case) is determined by the shear force of the portal itself. In this research, experiment had been done using multiple applicable methods for the SPSW, where the use of it depends on the architect aspect and necessity. In this experiment, the specimen will be tested with some applicable lateral loading, where in the steel plate itself, there are two openings applied to the web plate. The result of the research shows some behavior changing of the dissipating energy throughout the steel plate, especially along the edge of the openings. Because of that fact, there are some performance degradation in the specimen, compared to the normal steel plate with stiffeners, which is 26.61% reduction of ultimate strength (624.01) kN at perforated specimen, compared to 850.24 kN at non-perforated specimen) and 11.5% reduction of dissipated energy

Abstract

Indonesia is one of the countries located in the most active technonic plate area on earth. These conditions make Indonesia prone to earthquakes. So that the consideration of the load due to earthquakes in structural planning is very important to minimize the impact. Therefore, analysis of the performance of the 10-story reinforced concrete building structure using the response spectrum method and time history aims to determine the basic values of shear, displacement, deviation, and structure performance based on ATC-40. The structural design uses the example of a 10-story reinforced concrete building located in Aceh. The loads refers to SNI 1726:2019 and SNI 1727:2020. The maximum base shear value obtained is 116357.777 kN. The maximum displacement value obtained is 363.841 mm. The drift value does not meet the requirements according to SNI 1726:2019 Article 7.12.1. The structural performance is IO (Immediate Occupancy). Because the drift value does not meet the requirements, a structure evaluation was carried out using the base isolator HDRB HH075X4S. The analysis results show that the base isolator can reduce the base shear value of the structure by up to 73%. The value of displacement value after structural evaluation is 877.394 mm with most of the deformation occurring in the isolation plane so that the structure deforms less and can reduce the drift between floors. The drift value after the evaluation of the structure has met the requirements so that the structure is safer. Structure performance after the same performance evaluation, namely IO (Immediate Occupancy).

Abstract

Prediction of bearing capacity and soil type is a requirement for the safety of construction before planning a building construction. Therefore, it is necessary to research the distribution of bearing capacity and conical resistance to determine soil conditions in an area. Based on CPT data, this study mapped cone resistance distribution and soil-bearing capacity distribution in the ITK masterplan area. The analysis was carried out by reviewing the 40 cm pile foundation at 11 m. The analysis was carried out using the Kriging, IDW, and Spline with Barriers methods. The bearing capacity was analyzed using the Trofimankove method. The mapping of the carrying capacity using the three interpolation methods results in a Qall value of around 26,024 – 87,835 tons. The cone resistance mapping results using the three interpolation methods show that the soil consistent in the ITK masterplan area is stiff, very stiff and Hard with a qc value of around 16,0804 – 259,54 kg/cm2. The ITK masterplan area has a type of foundation soil, which is hard. The comparison results obtained from mapping the cone resistance and the carrying capacity of the three interpolation methods used, the value of the range of qc and Qall closest to the sample data used is the IDW method

Abstract

In construction world, there’re several changes with times. The cause of changes is connected to building construction cases such as the structure failing to bear the load. Earthquake and tsunami load have potentials to make building structure become a failure. Indonesia experienced a lot of earthquake and tsunami, because Indonesia is located on three big plates encounters which Eurasia, Indo-Australia, and Pacific Plate. Banten province is one of province that has experienced earthquake and tsunami. In record of 10 years, Banten has experienced 3 earthquakes and 1 tsunami. Because of that, there must be a study on the design of steel structure buildings in Banten that resist earthquake and tsunami. Purpose of the research is to get structure value of building design. Design was done by numeric analysist method based on updated Indonesian National Standard about steel building planning. The result of study are, the biggest beam dimension is WF 300x200x9x12. The biggest column dimension is KC 700x300x13x24. Using adhesive plate with 14 cm thickness. Bracing dimension is WF 350x350x12x19.

Abstract

Pariwisata perkotaan sangat perlu dikembangkan sesuai dengan potensi yang dimiliki setiap kota di manapun tanpa terkecuali. Urban tourism, salah satu jenis pariwisata, merupakan wisata yang memanfaatkan segala potensi baik sumber daya alam maupun manusia sebagai daya tarik wisata. Namun, permasalahan yang terdapat pada Kelurahan Sepinggan Baru, Balikpapan Selatan, adalah belum optimalnya pengembangan pariwisata daerah tersebut, sehingga potensi maksimal pariwisatanya belum dapat tercapai. Oleh karena itu, diperlukan sebuah usaha untuk mengawali pengembangan pariwisata ini. Salah satu cara yang dapat digunakan ialah memperbaharui gambaran umum (rebranding) Kelurahan Sepinggan Baru melalui urban tourism. Salah satu langkah nyata dalam proses rebranding adalah pembuatan situs web (website) guna memudahkan wisatawan lokal maupun mancanegara mengetahui situs wisata yang cukup banyak yang ada di Kelurahan Sepinggan Baru. Website urban tourism merupakan media promosi dan informasi yang dapat dijangkau dengan mudah melalui internet oleh siapapun dan kapanpun. Kehadiran website ini merupakan upaya dalam melakukan rebranding Kelurahan Sepinggan Baru berbasis urban tourism yang dapat membantu pengembangan wisata kota yang ada.

Abstract

Generally, brick wall (hebel) is considered as non-structural element, which never be counted to bear structural load. But, if carefully calculated, brick walls take part in structure load bearing. In the purpose of reducing the main structural element properties, the brick wall needs to be considered in bearing structural load. In this article, the brick walls modelled as compressive bracings. Using the structure analysis program, the model showed some significant differences in terms of internal force. From the analysis, the differences of moment, shear, axial and torsional force between open frame model (usual model, OF) and compressive bracing (CB) model were 38.17 kN.m; 58.03 kN; 181.75 kN dan 44.18 kN.m, respectively, where the first model had the bigger numbers than the latter model. Displacement of OF model was quite larger than CB model, with the value of difference was up to 85.35% for the X direction structures, and 70.83% for the Y direction. Final properties used for the design are smaller compared than original design, 30/60 to 40/60 for the beams, 50/50 for the columns with the different reinforcements 16-D22 for the second model compared to 20-D22 for the first one. The depth of slab on the second model was 180 mm, slightly smaller than the first model, 190 mm. It can be concluded that using compressive bracing model, structural properties of ITK Integrated Laboratory Building may greatly be reduced, compared to OF model.

Abstract

Kota Balikpapan merupakan salah satu kota dengan banyaknya sumber daya alam yang berlimpah dengan penyebaran perkebunannya. Berdasarkan Badan Pusat Statistik Kalimantan Timur tahun 2018 data produksi hasil perkebunan di tahun 2018 mencapai 8.846,9 ton, sedangkan untuk data produksi hortikultura di tahun 2018 mencapai 260.882 ton. Pada Kelurahan Karang Joang, Kecamatan Balikpapan Utara tepatnya di Jalan Giri Rejo RT.27 Kampung Semarang Mandiri, terdapat Kelompok Tani Karya Mukti dengan sumber daya yang melimpah. Seperti tanaman hortikultura dan perkebunan dengan hasil sumber daya hortikultura yang meliputi tanaman singkong, bengkoang, jagung, cabe kecil, terong, kacang panjang dan buncis. Kelompok Tani Karya Mukti masih menjalankan kegiatan pertanian dan pemasaran hasil panen secara konvensional, hasil panen yang berlimpah dan terkadang tidak laku terjual secara keseluruhan mengakibatkan para petani mengalami kerugian yang cukup besar. Sehingga untuk menghindari hasil panen yang membusuk begitu saja, para petani membagikan sayur-sayuran tersebut secara cuma-cuma kepada masyarakat sekitar misalnya seperti komoditi kacang panjang. Berlimpahnya hasil pertanian Kelompok Tani Karya Mukti untuk komoditi kacang panjang dapat dimanfaatkan untuk menjadi sebuah produk inovasi berupa tempe dari biji kacang panjang. Strategi pemasaran melalui pemanfaatan teknologi ini sangat memungkinkan untuk mendapatkan jangkauan pasar yang lebih luas sehingga keuntungan yang didapat pun juga semakin besar. Dengan memanfaatkan model pemasaran melalui digital marketing dapat membantu pelaku usaha dalam hal mempromosikan dan memasarkan produk dan jasa mereka tanpa adanya batasan jarak, waktu dan cara komunikasi.

Abstract

Potensi wisata merupakan salah satu sektor yang terus dikembangkan hingga saat ini. Perkembangan perencanaan wisata tidak hanya terbatas pada wisata alam dan buatan saja, melainkan juga memanfaatkan hasil perkebunan. Agroforestri merupakan konsep wisata yang menggabungkan pemanfaatan lahan antara tanaman hutan dengan tanaman perkebunan. Salah satu lokasi di Kota Balikpapan yang memiliki potensi untuk dikembangkan sebagai kawasan wisata agroforestri terletak di Jalan PDAM KM 12 RT 17 Karang Joang. Perencanaan pembangunan kawasan wisata ini memerlukan masterplan sebagai rencana induk perencanaan. Proses penyusunan masterplan kawasan wisata Waduk Manggar ini melibatkan masyarakat sekitar sebagai pengurus wisata. Metode yang digunakan dalam penyusunan masterplan ini meliputi observasi lapangan, diskusi pembuatan desain wisata, dan perancangan kawasan wisata. Rancangan wisata ini kemudian disampaikan kepada pengurus wisata dalam bentuk diskusi grup terfokus. Hasil dari pembuatan masterplan memberikan dampak positif kepada pengurus berupa kemudahan dalam pengelolaan dan perencanaan wisata jangka panjang. Selain itu, membantu pengelola dalam proses pengajuan dana pengembangan pariwisata kepada pihak pemerintahan maupun swasta. Kegiatan ini merupakan bagian dari program pengabdian kepada masyarakat yang bertujuan untuk memberdayakan masyarakat sekitar dan meningkatkan potensi wisata daerah.
