Abstract

Structural stability in construction, especially in buildings exposed to lateral forces due to earthquakes, is very important to consider. This research aims to explore the effectiveness of using Independent Wire Fibre Core (IWFC) steel wire rope braces in strengthening two-dimensional (2D) concrete portals. The method used is a series of laboratory tests to measure the performance of concrete portals equipped with IWFC braces. Concrete portals with dimensions of 1.00 m in the width direction and 1.50 m in the height direction were tested with lateral loading to simulate the effects of earthquakes. The test results showed that the use of IWFC braces increased the load resistance capacity of the portal by 16.13%, from 14.00 kN to 26.13 kN, and reduced the deviation by 30.43%, from 2.30 mm to 1.68 mm. In addition, the analysis showed an increase in the response modification factor (R) from 4.69 to 5.03, while the Cd value of the non-braced portal was 3.29 using braces was 3.02 and the Ω0 value of the non-braced portal was 3.50 and after using braces was 2.84. These findings open up opportunities for the application of better structural strengthening techniques in order to improve the safety and stability of buildings in earthquake-prone areas.

Abstract

This research was conducted to review the feasibility of beach sand from the Batu Bolong village of West Lombok Region as an alternative fine aggregate in concrete manufacturing. The background of this research is based on the decreasing supply of sand from rivers and mountains. The main objective of this research was to evaluate the compressive strength of concrete using beach sand, both with and without a washing process, and assess whether this material could be applied in structural construction. In addition to technical aspects, the local community's habit of utilizing beach sand is also part of the consideration in this study. The result oh the tests showed that the compressive strength of normal concrete without admixtures at 3, 7, and 28 days of age were 16.42 MPa, 19.21 MPa, and 23.39 MPa, respectively. The addition of the "BETON MIX" admixture increased the strength to 20.78 MPa, 23.38 MPa, and 26.44 MPa. Meanwhile, concrete using washed beach sand showed compressive strengths of 22.67 MPa, 23.61 MPa, and 25.16 MPa. The concrete with unwashed beach sand produced strengths of 21.72 MPa, 22.40 MPa, and 23.08 MPa. The results of this study indicate that sand from Batu Bolong beach has the potential to be a substitute for fine aggregate in concrete. However, its use must still consider ecological impacts so as not to disturb the balance of the coastal environment.

Abstract

The development of composite material engineering is an effective solution for the development of green building-based materials that are being campaigned in various parts of the country today. The fundamental problem in composite engineering that is developing is the lack of use of environmentally friendly materials as the basic material for composite constituents. The use of natural fiber-based composite materials as reinforcement is one of the right solutions to answer the issue of green building in producing more environmentally friendly materials with much better mechanical resistance. The study aims to determine the flexural characteristics of sandwich panel beams of sengon (SPS) in comparison to Meranti beams. The material used as skin for SPS beams is a composite of sisal fiber polyester from Sumbawa Island. Test standard based on ASTM C393 (length 550 mm, width 50 mm, thickness 25 mm), with a total of 5 specimens each. The test results showed that the SPS beams had an average bending stress of 167.66 MPa, while the Meranti wood beams produced an average bending stress of 94.29 MPa. The amount of bending stress produced by SPS beams is 43.38% higher than meranti wood beams. The average deflection value of SPS beams is 20.34 mm, greater than the average deflection value of sengon wood of 15.42 mm. This shows that the use of sisal polyester composite skin on SPS beams can produce better mechanical characteristics compared to Meranti wood.ABSTRAKPerkembangan rekayasa material komposit merupakan solusi yang efektif bagi pengembangan material berbasis green building yang sedang dikampanyekan di berbagai belahan negara saat ini. Permasalahan mendasar dalam rekayasa komposit yang tengah berkembang adalah minimnya penggunaan material ramah lingkungan sebagai bahan dasar penyusun komposit. Penggunaan material komposit berbasis serat alam sebagai perkuatan (reinforcement) merupakan salah satu solusi yang tepat guna menjawab isu green building dalam menghasilkan material yang lebih ramah lingkungan dengan ketahanan mekanis yang jauh lebih baik pula. Penelitian ini bertujuan untuk mengetahui karakteristik lentur pada balok sandwich panel kayu sengon (SPS) dengan pembanding balok kayu meranti (kayu kelas II). Material yang digunakan sebagai skin pada balok SPS adalah komposit polyester serat sisal yang dibudidayakan di Pulau Sumbawa, Nusa Tenggara Barat. Standar pengujian berdasarkan ASTM C393 (panjang 550 mm, lebar 50 mm, tebal 25 mm), dengan jumlah masing-masing 5 benda uji. Hasil pengujian menunjukkan balok SPS memiliki tegangan lentur rata-rata sebesar 167,660 MPa, sedangkan pada balok kayu meranti menghasilkan tegangan lentur rata-rata sebesar 94,292 MPa. Besarnya tegangan lentur yang dihasilkan balok SPS lebih tinggi 43,380% dibandingkan balok kayu meranti (kayu kelas II). Nilai lendutan rata-rata pada balok SPS sebesar 20,340 mm, lebih besar dibandingkan nilai lendtan rata-rata kayu sengon sebesar 15,420 mm. Hal tersbut menunjukkan bahwa penggunaan skin komposit polyester sisal Sumbawa pada sandwich panel kayu sengon mampu menghasilkan karakteristik mekanik yang lebih baik dibandingkan dengan kayu Meranti.

Abstract

Foundations are structural elements that function to bear the load of a building and transfer it to the ground to a certain depth. Foundations must be designed so that the transferred load does not exceed the bearing capacity of the soil, as this can cause excessive settlement and lead to structural collapse. The purpose of this study is to determine the comparison of bearing capacity and settlement of bored pile foundations in the Poltekkes Kemenkes Mataram building using two approaches: the manual method and the Allpile software. The analysis was conducted based on secondary data obtained from the Detailed Engineering Design (DED), results of the Standard Penetration Test (SPT), and laboratory soil test results. The results of the manual Meyerhof method yielded an ultimate bearing capacity of 13,127.79 kN and a single pile settlement of 0.0455 m. The manual Reese and Wright method yielded an ultimate bearing capacity of 2,697.3453 kN and a single pile settlement of 0.0241 m. Meanwhile, the Allpile software calculation yielded an ultimate bearing capacity of 14,391.891 kN and a single pile settlement of 0.0027 m. All settlement values, both for single piles and groups, remain below the maximum permitted limit.

Abstract

Penelitian ini bertujuan untuk mengevaluasi pemanfaatan pasir besi dan pasir pantai sebagai substitusi sebagian agregat halus pada campuran Asphalt Concrete – Binder Course (AC-BC) serta menentukan proporsi optimum yang mampu memenuhi persyaratan kinerja menurut Spesifikasi Bina Marga 2018 Revisi 2. Pengujian laboratorium dilakukan menggunakan pasir besi dari Pantai Kerakat dan pasir pantai dari Pantai Malimbu, sedangkan agregat kasar dan abu batu diperoleh dari AMP setempat. Pengujian Marshall dilakukan dengan kadar aspal optimum sebesar 5,15% dengan parameter yang dianalisis meliputi stabilitas, kelelehan, Marshall Quotient, Void in Mineral Aggregate (VMA), Void in Mix (VIM), dan Void Filled with Bitumen (VFB). Hasil penelitian menunjukkan bahwa meskipun beberapa campuran tidak memenuhi kriteria VIM dan VFB, dua variasi 5% pasir besi + 5% pasir pantai dan 7,5% pasir besi + 2,5% pasir pantai menunjukkan keseimbangan interaksi antarbutir, interlock agregat yang baik, dan struktur internal yang stabil sehingga memenuhi seluruh spesifikasi yang dipersyaratkan. Secara ilmiah, pencapaian kinerja tersebut disebabkan oleh karakteristik pasir besi yang meningkatkan kerapatan struktur dan pasir pantai yang memperbaiki kemampuan kerja sehingga mencegah over compaction. Sebaliknya, campuran dengan dominasi pasir pantai menghasilkan rongga udara tinggi, sedangkan campuran dengan dominasi pasir besi menjadi terlalu rapat, keduanya menyebabkan ketidaksesuaian spesifikasi. Secara keseluruhan, penelitian ini membuktikan bahwa proporsi terkontrol dari kedua material lokal ini dapat dimanfaatkan secara efektif sebagai substitusi agregat halus dalam campuran AC-BC
