Abstract

Self-Compacting Concrete (SCC) is an innovative solution in today's world of concrete technology. Unlike traditional concrete, it does not require a vibrator for compaction, which makes concrete work easier. One of the key features of SCC is its high workability, which is achieved through the use of chemical admixtures and mineral additives. Rice husk ash is one such additive that can be used as a pozzolanic material for concrete mixtures, which is important as rice husk waste can cause environmental problems. The objective of this study was to investigate the effect of rice husk ash on SCC concrete. The study involved using Rice Husk Ash (RHA) as a partial replacement for cement in SCC concrete at varying percentages (0%, 5%, 10%, and 15% of cement weight). The results of the slump flow test showed that the highest value of 775 mm was achieved at 15% RHA, meeting the specifications of SCC concrete. In terms of compressive strength, the results showed that the SCC mixture without rice husk ash (0% RHA) had the highest average compressive strength, which was 30.56 MPa at 14 days and 31.66 MPa at 28 days of concrete. On the other hand, the average compressive strength of SCC concrete with rice husk ash mixture was highest at 5% RHA, with 25.04 MPa at 14 days and 28.81 MPa at 28 days. Overall, the study found that the use of rice husk ash in SCC concrete had a significant effect on its compressive strength, with the highest compressive strength being achieved at 5% RHA.

Abstract

The fire of a building will have a major impact on the building owner, both in the form of material, moral and environmental losses. In residential areas, offices and other public facilities often cause casualties. Therefore, a building needs to take into account the risk of fire so that building users can carry out activities safely and comfortably. One of the causes of fires is the fire suppression system that has not received full attention, where there is often an inadequate building fire protection system. The UNP Library Building is one of the public facilities buildings that are always crowded with students. It is necessary to evaluate the availability of the fire protection system to ensure the safety and comfort of its users. This research is in the form of an evaluation of the availability and completeness of the available fire protection systems and their remedies against the threat of fire. The data was taken through direct observation and question and answer and the distribution of questionnaires with the library. From the results of the analysis of the fire protection system inspection of the UNP Library building, it is known that on the 1st floor the lowest rediness value is 18.9%, for the 2nd and 3rd floors is 44.1%, the 4th and 5th floors are 45.9% and 45.6 % fulfilled the requirements based on the Minister of Public Works Regulation No. 26/PRT/M/2008.

Abstract

Abstrak Hunian vernakular adalah karya masyarakat yang digali dari potensi setempat sesuai dengan daya dukung lingkungannya sehingga menghasilkan kekhasan produk tersendiri antara kelompok masyarakat satu dengan yang lainnya. Tujuan penelitian ini adalah mengkaji perilaku struktur hunian vernakular Suku Rejang Desa Gunung Alam dalam merespon gaya gempa. Metode penelitian dilakukan dengan tahapan sebagai berikut: survai lapangan dengan melakukan pengukuran secara langsung dan detail terhadap semua elemen penyusun rumah. Membuat model struktur digital. Menganalisis model struktur dengan bantuan perangkat lunak SAP 2000. Membuat simulasi respon model struktur terhadap beberapa jenis beban gempa. Menganalisis kapasitas elemen struktur rumah dan dibandingkan dengan tegangan lentur yang terjadi pada saat terjadi pembebanan ekstrim dan gempa rencana kala ulang 50 tahun. Hasil penelitian menunjukkan bahwa analisis kapasitas elemen struktur rumah Ibu Kabat mengacu pada SNI 7973-2013 dengan nilai desain acuan dimodifikasi, kapasitas elemen balok kayu lebih besar 12,87% dibandingkan dengan tegangan lentur balok yang terjadi. Elemen struktur kolom kayu, nilai hasil persamaan interaksi lebih rendah 49,880%. Fakta lapangan menunjukkan bahwa rumah panggung di Desa Gunung Alam yang telah berusia lebih dari     50 tahun, sampai saat ini masih kuat dan tetap berdiri kokoh.

Abstract

A bridge is a construction structure whose role is to connect one place to another by crossing a natural or artificial obstacle. Bridge conditions can be caused by many factors such as the influence of weather, traffic loads, the environment, material durability, and so on. Good bridge conditions can be achieved if maintenance is carried out regularly. Therefore, assessing or checking the condition of the bridge is very necessary so that disturbances caused by the factors above can be avoided before an accident occurs. From the results of the field survey, it was found that 52.11% of bridges were in Good condition, 27.46% in Lightly Damaged Condition, 16.90% in Damaged Condition, 2.82% in Severely Damaged Condition and 0.70% in Critical Condition. . The bridge condition assessment was carried out for 2 weeks by carrying out inventory checks, detailed surveys and routine surveys on each bridge.

Abstract

A Systematic Review of Sustainable Higher Education Assessment System: Indicators, Models, and Future Directions. Objective: Evaluation of the sustainability of higher education institutions (HEIs) has become a major focus in academia, especially as evaluation and ranking systems have evolved into increasingly complex ones. This study aims to provide a set of simple indicators for national policy makers to facilitate the measurement of progress towards sustainability in the higher education sector. Methods: Using a qualitative descriptive approach and a Systematic Literature Review (SLR) method, this study examines 16 types of higher education ranking systems and 16 previous research findings based on the UNEP sustainable higher education framework policy, in order to develop a set of indicators specific to the sustainable higher education sector. Articles were selected using the keywords "sustainable higher education" OR "Sustainable performance measurement" and "Performance indicator AND sustainable HEIs" through a systematic screening process that was in line with the inclusion criteria, including relevance to indicators for assessing sustainable higher education performance. Findings: The results of this study revealed areas that were not yet filled, especially in the criteria that combine all pillars holistically. Previous researchers assessed higher education using only part of the four pillars of sustainability identified by the UN, based on the reviewed literature, it was found that 37.5% of researchers used 3 pillars, 25% of researchers used 2 pillars and 37.5% of researchers used 1 pillar of sustainable higher education. This shows that there is an opportunity for further research that can integrate all aspects of higher education sustainability holistically. This multidimensional approach is important to provide a more complete and comprehensive picture of the performance and contribution of higher education in the context of sustainability. Conclusion: It is necessary to develop a comprehensive and integrative evaluation method, as well as identify performance indicators that measure the impact of interactions between pillars to provide a more comprehensive picture of higher education sustainability. Further research is also needed to bridge the gap in the literature and strengthen the multidimensional approach in assessing sustainable higher education performance. Keywords: model, sustainability indicators, higher education, sustainability.
