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

Choosing the right roofing material is an important aspect of building design and construction. Both residential and commercial buildings have roof-related needs. But basically, the selection of roofing materials is not only for protection from but also based on energy efficiency, aesthetics, and longevity of the building. In addition, the design of roof shape selection must be done carefully because the wrong selection can cause rainwater seepage or leakage on the roof and high repair costs. This research aims to explore by comparing the characteristics of roof covering materials and provide the best choice based on needs. The research method used is a qualitative research method with the stages carried out, namely data collection techniques, sample determination, data analysis and research conclusions. Based on the analysis, it is concluded that for residential houses, tile roofs and concrete deck roofs are the best choice because they offer an optimal combination of aesthetics, durability, energy efficiency, and cost that is suitable for the Indonesian climate. While for commercial buildings, metal tile roof is an excellent choice due to its durability, energy efficiency, and modern aesthetics that suit the needs of commercial buildings.

Abstract

Perbaikan dan perkuatan struktur di perlukan apabila terjadi kerusakan yang menyebabkan degradasi yang berakibat tidak terpenuhinya lagi persyaratan persyaratan yang bersifat teknis. Secara umum dilakukannya perkuatan disebabkan oleh beberapa hal antara lain yaitu Kesalahan perencanaan, Kesalahan pelaksanaan, Perubahan fungsi yang berakibat penambahan beban,Perkembangan ilmu pengetahuan,Timbulnya keluhan terhadap kenyamanan struktur, Perubahan persyaratan untuk memenuhi peraturan Yang baru. Tahapan perkuatan struktur dapat dilakukan dengan cara review struktur, Analisis struktur, metode dan material perkuatan dan pelaksanaan. FRP juga dinilai sebagai alternatif perkuatan eksternal yang murah tapi mampu meningkatkan kinerja pada struktur bangunan. Pada metode ini, dua jenis serat yang paling banyak diaplikasikan adalah Glass Fiber Reinforced Polymer (GFRP), Carbon Fiber Reinforced Polymer (CFRP), dan aramid atau serat kaveler. FRP memiliki daya tarik tujuh hingga sepuluh kali lebih besar dibandingkan baja. Keunggulan dari perkuatan FRP ini yaitu bahan lebih ringan, kekuatan tarik tinggi, tidak terjadi korosi sehingga memiliki durabilitas (keawetan) yang tinggi, mudah dalam pemasangannya sehingga menghemat waktu serta bahannya mudah untuk dibentuk (fleksibel).

Abstract

Sektor energi sangat berpengaruh terhadap aktifitas masyarakat seperti kegiatan rumah tangga, sosial budaya, industri, perdangan, dll. Pada tahun 2021, meskipun rasio elektrifikasi Provinsi Sumatera Barat sudah mencapai 98.81%, penyediaan energi listrik tetap menjadi salah satu prioritas pembangunan. Sebenarnya Indonesia memiliki potensi cadangan energi baru terbarukan yang besar seperti radiasi matahari, energi angin, energi air, biomassa, dll. Namun pengembangan teknologi pembangkit energi baru terbarukan belum maksimal karena tingginya biaya investasi dan perawatan. Penelitian ini bertujuan untuk melakukan rancang bangun sebuah pembangkit listrik tenaga piko hidro. Berdasarkan hasil analisis karakteristik aliran dan kondisi lapangan jenis turbin air yang sesuai untuk head dan debit yang rendah adalah turbin aliran silang (cross flow). Pembangkit Listrik Piko Hidro ini diharapkan mampu memenuhi kebutuhan energi bagi beberapa kepala keluarga sehingga dapat meningkatkan produktifitas kerja, tingkat pendapatan dan kesehjateraan warga pada daerah pedalaman.
