Abstract

Abstract: Emergency Installation Building is one of the existing buildings in the Meuraxa Hospital Complex consisting of several buildings with the location on the Soekarno Hatta street km 2 City Banda Aceh. The tropical climate of Banda Aceh region with temperatures ranging from 25.5 to 32.5 is located in the northern hemisphere causing the sun shining 12 hours each day resulting in high consumption of electrical energy caused by the use of artificial weather carriage. The development of the city that seemed modern and futuristic is an architectural phenomenon characterized by the use of dominant glass on the building sheath as well as the facade of RS.Meuraxa Emergency Installation Building. . In the effort of government energy conservation through National Standardization of Indonesia in SNI 03-6389-2011 stated that maximum thermal transfer value limit on the outer wall or called Overall Thermal Transfer Value (OTTV) is 35 Watt / m2. This research aims to generate a reference design of sheath and get the factors that affect the amount of OTTV value from the results of simulating the calculation toward all variables. The calculation result obtained the total value of OTTV is 51,47 Watt/m2. To decrease the result, some variation of modification simulation by inputting all data of the coefficient value of the material which likely to be applied in the design. The simulations consist of Uf modifications (double glazing), Uw (Outer Wall Isolation), WWR (Glass comparison ratio), (paint color), SC (shield). The simulation results are included in the table and trendline linear graphs so that the slope value is obtained to analyze the influence / significance level toward OTTV value. The result of the research shows that the modification of SC (glass and effective) by installing shade and modification of glass specification greatly influences the decrease of OTTV value in the effort of energy conservation by still presenting the concept of tropical architecture with traditional theme of Aceh.Abstrak: Gedung Instalasi Gawat Darurat merupakan salah satu dari gedung yang ada di Komplek Rumah Sakit Meuraxa yang terdiri dari beberapa bangunan dengan lokasi berada di jalan Soekarno Hatta km 2 Kota Banda Aceh. Wilayah Banda Aceh yang beriklim tropis dengan suhu berkisar antara 25,5 hingga 32,5 berada di belahan bumi Utara menyebabkan matahari bersinar 12 jam setiap harinya terus menerus setiap tahunnya sehingga berdampak pada tingginya konsumsi energi listrik akibat dari penggunaan penghawaan buatan. Perkembangan kota yang berkesan modern dan futuristik merupakan fenomena konsep tampilan bangunan dengan bercirikan penggunaan kaca yang dominan pada selubung bangunan seperti halnya yang diterapkan pada bangunan gedung IGD Rs.Meuraxa. Dalam upaya konservasi energi pemerintah melalui Badan Standarisasi Nasional Indonesia yang dimuat dalam SNI 03-6389-2011 menentukan batasan nilai perpindahan termal menyeluruh pada dinding luar atau disebut dengan Overall Thermal Transfer Value (OTTV) maksimal 35 Watt/m2. Penelitian ini bertujuan menghasilkan acuan desain selubung dan mendapatkan faktor penyebab yang mempengaruhi besaran nilai OTTV dari hasil melakukan simulasi perhitungan terhadap semua variabelnya. Perhitungan OTTV pada IGD RS.Meuraxa terdiri 3 komponen nilai yaitu: nilai konduksi dinding, radiasi matahari dan konduksi kaca terhadap empat orientasi fasad bangunan dengan perolehan hasil total nilai OTTV 51,47 Watt/m2. Untuk menurunkan nilai dilakukan beberapa variasi simulasi modifikasi dengan menginput semua data nilai koefisien material yang dimungkinakan untuk diaplikasikan dalam desain. Simulasi terdiri dari modifikasi Uf (kaca ganda), Uw (Isolasi Dinding Luar), WWR (Rasio perbandingan kaca), a (warna cat), SC (alat peneduh dan spec.kaca). Hasil simulasi dimasukkan dalam tabel dan grafik trendline linear sehingga didapatkan nilai slope /kemiringan untuk dianalisis tingkat pengaruh/ signifikan terhadap nilai OTTV. Hasil penelitian diperoleh bahwa modifikasi SC (kaca dan effectif) yaitu pemasangan alat peneduh dan modifikasi spesifikasi kaca sangat mempengaruhi penurunan nilai OTTV dalam upaya konservasi energi dengan tetap mengedepankan konsep arsitektur tropis yang bertemakan tradisional Aceh.

Abstract

Abstrak Sambungan pelat ujung (end plate connection) adalah sambungan semi kaku yang secara umum digunakan untuk menghubungkan balok-kolom. Salah satu alternatif untuk meningkatkan kapasitas lentur sambungan adalah memperluas area sambungan pelat ujung. Namun, upaya yang dilakukan tersebut butuh dievaluasi lebih lanjut. Penelitian ini bertujuan untuk menginvestigasi kuat lentur sambungan pelat ujung dengan memberikan beberapa perkuatan yaitu penambahan area sambungan, pemasangan pengaku pelat badan, dan perpanjangan penyokong di area bawah balok. Untuk mengevaluasi signifikansi perkuatan, benda uji tanpa perkuatan (ordinary end plate connection) digunakan sebagai acuan. Penelitian dilakukan melalui pemberian beban geser yang ditempatkan pada 400 mm dari sambungan dan beban ditingkatkan secara bertahap hingga benda uji gagal. Kajian eksperimental menunjukkan benda uji dengan kombinasi perkuatan berupa penambahan area sambungan dan penambahan pengaku badan memberikan kuat geser dan lentur yang paling baik. Kajian teoritis mengacu ke SNI 03-1729-2020 menunjukkan kuat lentur nominal lebih kecil dibandingkan kuat lentur eksperimental. Hal ini menunjukkan kajian teoritis memberikan kuat lentur lebih konservatif. Kata-kata Kunci: Sambungan pelat ujung, sambungan ordinary end plate, sambungan extended end plate, kuat lentur, kuat geser, deformasi Abstract An end plate connection is a semi-rigid connection used to connect a beam to a column. One alternative to improve the flexural strength is to enlarge the end plate connection area. However, this strengthening approach needs to be more specifically investigated. This study aims to evaluate the flexural strength of the connections by several strengthening methods: enlarging the connection area, installing web stiffeners, and lengthening the haunch at the bottom side of the beam. To examine the significance of strengthening approaches, an un-strengthened specimen (ordinary end plate connection) was considered as the reference. The research work was first carried out by positioning the shear load at a distance of 400 mm from the connection area, and it was gradually increased until the specimens failed. The experimental study also revealed that the specimen strengthened by combining an enlarged connection area and web stiffeners performed the best in terms of shear and flexural strength. The theoretical study referring to the SNI 03-1729-2020 demonstrated the nominal flexural strength, which is smaller than the experimental flexural strength. This behavior showed that the theoretical study provided more conservative flexural strength.

Abstract

The type of material, mixture composition, and production process are among the factors that influence the strength of interlock bricks. In this study, interlocking bricks are used for the construction of residential wall structures. The interlocking brick mixture consists of cement, fly ash, sand, and water. The fly ash and sand used have a maximum diameter of 4.75 mm and are not subjected to calcination. Interlocking bricks measuring 30 cm x 20 cm x 10 cm are molded using a manual hydraulic press and cured for up to 28 days before being cut into test specimens measuring 5 cm x 5 cm x 5 cm. A total of 150 test specimens from 5 mix designs using water-cement ratios (WCR) of 0.3, 0.4, and 0.5 were utilized in this study. The objective of this research is to determine the quality levels of interlocking bricks based on compressive strength tests at 28 days of age. The quality levels are determined according to the Indonesian National Standard, SNI 03-0349-1989. Based on the compressive strength results, it was found that the average interlocking bricks with fly ash mixture achieved class III quality, indicating that they can only be used for non-structural wall applications.

Abstract

Tides are the dominant physical process in the coastal environment. During high tide, water from the ocean flows through the bays and estuaries, causing inundation and raising water elevation. When low tides condition, the water level becomes lower than average and recedes into the sea. This process continues for a long day. Tsunami waves will interact with all coastal processes and affect the hydrodynamic forces of tsunami waves. In the deep sea, tides do not significantly influence wave propagation. However, in the shallow water zone, tides can change tsunami heights and affect the extent of inundation. Tides are usually ignored in tsunami hazard analysis. This would be an underestimate of the tsunami hazard calculation. This study aims to investigate tides' influence on tsunami runup hydrodynamics in Banda Aceh. The potential tsunami from an earthquake in the Aceh-Andaman subduction zone is modeled using COMCOT (Cornell Multi Grid Coupled Tsunami Model) with magnitudes Mw 9.2, 8.6, and 8.2. We simulated the response of the three earthquake magnitudes on two different types of high and low tides. Several virtual gauges were placed to observe the tsunami height. Virtual gauges were also used to observe the tsunami arrival time at four tsunami escape buildings in Banda Aceh: the Ulee Lheue escape building, the Deah Glumpang escape building, the Alue Deah Teungoh escape building, and the Lambung escape building. The results show that the highest tide amplifies the tsunami inundation will be extended to about 30% farther inland compared to the condition if the tsunami occur during mean sea level condition.The interactions between tsunami and high tide significantly shorten tsunami arrival time on small magnitude tsunamis and are not significant in a large tsunami. This information is useful for enhancing early warning systems and evacuation procedures that can be adjusted to the tidal conditions in the study area.
