Kondisi tektonik Indonesia terletak pada pertemuan lempeng besar dunia dan kecil, sehingga memberi dampak bahwa wilayah tersebut berpotensi akan sering terjadi gempa. Kota Surabaya dikategorikan sebagai ibukota yang cukup padat, sehingga potensi terjadinya bahaya gempa bumi yang berasal dari sesar Kendeng terbukti aktif serta melakukan pergerakan 5 milimeter per tahun. Menyadari fenomena tersebut merupakan hal yang mutlak sebagai bahan pertimbangan dalam mendisain dan membangun bangunan di wilayah seluruh Indonesia. Sebagai usaha memperkuat pembelajaran terutama pengenalan desain seismik pada mahasiswa Arsitektur, sehingga perlu diteliti prinsip (faktor) yang mempengaruhi desain seismik dengan studi kasus adalah gedung perpustakaan kampus I UINSA, sebagai kajian studi alternatif desain bangunan terhadap ketahanan gedung akibat beban lateral. Metode penelitian adalah deskriptif kuantitatif selanjutnya dianalisis menggunakan software Resist 4,0. Prinsip atau faktor desain sei...

Namun bambu juga dikenal memiliki beberapa kelemahan, diantaranya rentan terhadap serangan rayap dan jamur bila terkena air. Oleh karenanya diperlukan perlakuan khusus untuk memperpanjang usia penggunaan bambu bila hendak digunakan sebagai material konstruksi. Metode pengawetan dengan perebusan adalah salah satu metode baru yang diterapkan dilapangan untuk memenuhi pasokan bambu awet, selain metode Visual Soak Diffusion (VSD) yang cenderung memakan waktu yang lebih lama. Tujuan penelitian ini adalah untuk mengetahui sifat mekanik kuat-lentur bambu Petung dengan metode pengawetan perebusan. Hasil pengujian memperlihatkan peningkatan kuat-lentur bambu yang signifikan (dua puluh persen lebih kuat-lentur) setelah diawetkan dengan metode perebusan, meskipun kadar air dalam bambu meningkat yang berimbas pada potensi serangan jamur. Hal ini dapat diatasi dengan cara menambahkan bahan anti jamur pada larutan pengaweta...

The types of timber used were Toona sureni (specific gravity 0.45), Swietenia mahogany (specific gravity 0.51) and Artocarpus heterophyllus (specific gravity 0.54) and concrete with actual compressive strength of 15.93 MPa. Lag-screw in 8 mm diameter (length 130 mm), washer in 22.8 mm diameter and fischer S14 were also used. The percentages results of shear resistance (5% offset method) between the predictions and experiment were 36,40% until 48,15%. These results showed that shear resistance to predicted equation of EYM was close enough to shear resistance based on the test results

Installation of anchor done by predrilled holes in the wood first and then the local casted with foundation. In its development, the wooden house can be made in the form of assembled or knocked down. So, what if the connection should be investigated with beams foundation is connected with using a lag-screw and foundation pedestals replaced with concrete foundations without reinforcement. In this study, the evaluation of lateral resistance was carried out by testing the shear joint with monotonic loading and the analysis method was adopted from EYM (European Yield Model). The woods used in this study included: Toona sureni (specific gravity: 0,45), Swietenia mahagoni (specific gravity:0,51) and Artocarpus heterophyllus (specific gravity:0,54) with actual concrete qualities of 15,93 MPa and 21,27 MPa. Diameters of the lag-screw, covering ring and Fischer were 8 mm (130 m...

Among its uniqueness is an irreplaceable building material between one another. However, weaknesses are also found in them especially related to termites or powder beetles. To be able to obtain maximum results in the use of these two materials, the preservation process was needed as a special treatment. With a variety of Bamboo preservation techniques, this paper tries to identify and examine various studies and best practices related to the Bambu-kayu preservation method in Indonesia. A qualitative approach was used with literature study techniques, field observations and in-depth interviews with entrepreneurs in preserving bamboo. From the results of the study obtained an illustration that the preservation method carried out depends on the needs of the user. It is also known that 10% Borak Boric concentrate has been able to be a chemical preservative that can be trusted to maximize material age. Ther...

The provision of drinking water throughout Indonesia is an obligation that has been stated in UUD 45. Based on the Bappenas study with the Ministry of Public Works, universal access to drinking water is targeted to reach 84,8% nationally. Then, this universal access must increase to 92,2% in 2018. In the end, access to drinking water for the community in 2019 is 100%. Based on this description, every region in Indonesia must have universal access to proper drinking water. Manggarai Regency is one of the districts that will alleviate the problem of universal access to drinking water. Existing water sources in Manggarai Regency are in various locations of hills and mountains. This water source is a source of water that can be used as a source of drinking water. Based on the study of SPAM Master Plan, residents of Manggarai Regency who have had access to adequate drinking water are 57.61%. The percentage value is still below the threshold of d...

At the same time, through the systematic test, the influences of the aggregate strength, water-binder ratio, fly-ash content, etc on ceramsite concrete are studied. Finally the best mixture ratio scheme for ceramsite concrete is gained, providing theoretical basis for the application of lightweight aggregate concrete.

Pemakaian bahan material yang tidak dapat diperbaharui dalam jangka waktu tertentu akan habis dan efek yang ditimbulkan merusak lingkungan. Penerapan material ekologis yang merupakan pemenuhan aspek pada konsep green building menjadi topik yang terus dikaji oleh peneliti atau praktisi. Bambu memenuhi kriteria sebagai alternatif penerapan material ekologis. Berbagai potensi bambu baik unsur kekuatan, cepat tumbuh, rendah energi, dan bahan melindungi ekosistem bumi termasuk peningkatan ekonomi. Kendala bambu adalah mulai tergerus oleh perkembangan teknologi modern. Bambu sebagai penopang kehidupan sehari-hari mulai kehilangan identitasnya yang mengakibatkan pasokan material bambu atau keberlangsungan material bambu, perlahan di masyarakat mulai langka/sulit dicari. Oleh sebab itu, material bambu dapat digunakan sebagai material ekologis dengan terobosan dalam hal modernisasi pemanfaatan bambu...
