Paper ini membahas penyebab fenomena ketidak-simetrisan pola penggelembungan akibat pembebenan pada dinding silo yang menggunakan modul dinding corrugated dengan sambungan baut. Kapasitas penyimpanan silo yang diobservasi adalah 4650 ton biji gandum berdiamater 19 m dengan tinggi 20,875 m. Analisis numerik dilakukan dengan menggunakan metode elemen hingga. Kondisi sambungan baut diukur secara langsung dengan menggunakan kunci torsi. Pengukuran dan analisis dilakukan pada saat silo terisi penuh maupun kosong. Hasil pengukuran menunjukkan bahwa pada saat diisi biji gandum secara penuh, besar torsi pengencangan baut pengikat antar modul dinding sekitar 2x torsi pengencangan baut pada saat kosong. Hal ini menunjukkan bahwa dinding silo dikenai tegangan geser oleh baut. Adapun ketidak-simetrisan pola penggelembungan dinding pada saat pembebanan disebabkan karena bervariasinya torsi kekencangan baut pada sambungan antara modul dinding. Dari hasil perhitungan diperoleh bahwa torsi kekencangan baut minimum untuk menghasilkan tegangan gesek (pada bidang overlap sambungan antar modul dinding) yang sama dengan tegangan desak grain adalah sebesar 47,36 Nm.

Tujuan dari penelitian ini adalah menganalisis potensi pemanfaatan bubuk cangkang telur (egg shell powder, ESP) untuk menggantikan kapur pada stabilisasi tanah-kapur. Bubuk cangkang telur diketahui mengandung kalsit dalam jumlah yang besar. Batas-batas konsistensi biasanya digunakan untuk menilai workabilitas dan memperkirakan perubahan sifat mekanik tanah yang distabilisasi. Dalam penelitian ini digunakan kapur tohor (quicklime) dan kapur padam (hydrated lime). Initial Consumption of Lime (ICL) diperoleh dengan menggunakan uji pH metode Eades and Grim, hasil pengujian didapatkan ICL 8%. Variasi pengujian yang dilakukan adalah dengan mensubtitusi sejumlah kapur dengan ESP, yaitu 0%, 25%, 50%, 75% dan 100% dari ICL. Hasil pengujian menunjukan bahwa dengan stabilisasi kapur indeks plastistas menurun sebesar 55%-60%. Semakin banyak kadar kapur yang disubtitusi dengan ESP menyebabkan peningkatan indeks plastisitas dibandingkan stabilisasi tanah-kapur. Tetapi, pada subtitusi seluruh kadar kapur dengan ESP, indeks plastitas tanah menurun sebesar 29% dibandingkan tanah asli. Batas susut tanah asli 10,43%, setelah distabilisasi dengan 8% bubuk cangkang telur batas susutnya menjadi 13,22% , terjadi peningkatan 26%, sedangkan rasio susut, susut volumetrik, dan susut linear penurunannya tidak signifikan. Jenis kapur (kapur padam dan kapur tohor) memperlihatkan perilaku perubahan plastisitas tanah yang hampir sama.. Bubuk cangkang telur dapat digunakan untuk bahan stabilisasi tanah, dan mampu merubah plastisitas tanah, tetapi perubahan plastisitas yang terjadi tidak sebesar stabilisasi menggunakan kapur.

Surface peak ground acceleration (PGAM) needs for seismic forces of basement and retaining structures design. The PGAM value can be calculated using bedrock peak ground acceleration (MCEG) and multiplied it with site coefficient FPGA. For building design purposes, the MCEG value can be calculated based on the combination of DSHA (Deterministic Seismic Hazard Analysis) and PSHA (Probabilistic Seismic Hazard Analysis). Compared to the previous 2012 website response spectrum design which is displayed the PGAM value, only MCEG value at site position can be obtained from the new 2021 response spectrum design website. This paper describes the development of PGAM distribution of Semarang using Visual Basic programming language software. The distribution of DSHA and PSHA (2500 return periods) combination analysis for developing MCEG value also describes in this paper. The analysis was performed based on the earthquake record data from 1900 to 2016. The PGAM analysis was performed at 203 soil boring investigation positions and using FPGA site coefficients of SNI 1726:2019. The minimum and maximum PGAM distribution values at the study area are in between 0.45 through 0.55 g and the maximum PGAM is distributed at the northern part of the study area.

Likuifaksi merupakan fenomena kegagalan pada lapisan tanah yang umumnya terjadi akibat beban siklik akibat gempa bumi. Penelitian ini dilakukan untuk mengetahui potensi likuifaksi berdasarkan distribusi ukuran butir tanah dan data CPT di kawasan Rumah Sakit UII Desa Wijirejo, Bantul, DIY. Berdasarkan letak geografisnya, Kabupaten Bantul memiliki potensi gempa yang tinggi dikarenakan berada di dekat sesar opak serta berada di zona subduksi antara lempeng Indo-Australia dan Lempeng Eurasia. Seiring dengan hal tersebut maka ada urgensi untuk penelitian ini. Analisis berdasarkan distribusi ukuran butir tanah dievaluasi menggunakan kurva Tsuchida (1970). Analisis berdasarkan data CPT dievaluasi menggunakan persamaan Seed & Idris (1971) dan IM Idriss & RW Boulanger (2008) untuk mendapatkan nilai keamanan lapisan tanah, yang kemudian digunakan untuk memprediksi tingkat potensi likuifaksi dengan nilai LPI menggunakan persamaan Luna & Frost (1998). Hasil penelitian menunjukkan bahwa kawasan Rumah Sakit UII memiliki potensi likuifaksi yang sangat tinggi. Berdasarkan distribusi ukuran butir menggunakan kurva Tsuchida (1970) di Desa Wijirejo, lapisan tanah pada kedalaman 1 meter didominasi oleh tanah berpasir dan lanau yang berpotensi likuifaksi. Berdasarkan data CPT, seluruh titik sondir memiliki potensi likuifaksi yang sangat tinggi dengan nilai LPI berturut-turut sebesar 48.405; 52.160; 57.498; dan 46.942 dengan kedalaman zona potensi likuifaksi 0,20 sampai 13,20 meter dari permukaan tanah.

The use of cement as the main binding agent in construction contributes approximately 7-10% in total of carbon dioxide gas emissions worldwide. In this study, the replacement of Portland cement using ground granulated ferronickel slag (GFNS) activated by the combination of sodium hydroxide (NaOH) dan sodium silicate (Na2SiO3) was utilized for producing alkali-activated mortar (AAM) as construction material. Four different mortar mixtures were prepared in this experimental work. There were three mixtures of ferronickel slag-based alkali activated mortar (FAM) with the variations of NaOH molarity of 6, 8, and 10M and cement-based mortar mixture (PCM) with water-to-cement ratio (w/c) of 0.5 was used as the control specimens. Overall, the flow and workability of the FAM specimen was lower than the PCM specimen due to the presence of silicate caused a sticky characteristic on the paste. On the other hand, the unit weight of FAM mortar was higher than the PCM specimen. Among all FAM mixtures, the most effective compressive strength and splitting tensile strength results were achieved by the FAM8 mixture, with a compressive strength at 28 days of 33.72 MPa and the splitting tensile strength at 28 days of 2.65 MPa, which had both good workability and chemical reaction of the material.

The river is one part of the water resources infrastructure, in addition to drive the water, river is often transporting sediment. Sediment is the result of erosion and is part of problems in the river. Unda watershed having their regional coverage is quite wide, so that erosion that causes to the passage of it is estimated that sedimentation large enough. This research analyze the total weight of the sediment that is settles on the downstream Tukad Unda and compare the analysis of sedimentation between USLE method and sedimentation method in HEC-RAS by supporting ArcGIS and HEC-GeoRAS so that can describing the shape of look over profile of to scatter the sediment that was formed, as well as the efforts to overcome the problems. The data used in the form of watershed area, soil type, rain and river flow. Furthermore, the method used is Universal Soil Loss Equation (USLE), the application of HEC-GeoRAS and ArcGIS. The results showed the average erosion that occurred in the last 10 years amounted to 30.57 tons/ha/year, then the results of the HEC-GeoRAS analysis showed that the river bed profile changes experienced a significant silting of 2,365 m3 using the application and 2,654 m3 with USLE method. Countermeasures can be done by normalizing the riverbed with regular dredging at the stationing point UD 64-60 then at the stationing point UD 55-57 and at stationing UD 45-41 in accordance with the analysis results obtained through the HEC-GeoRAS application.

Many buildings in Indonesia were damaged during the earthquake, especially non-engineered brick walls building. One example of non-engineered brick walls building is Bendung Village Head Office in Serang, Banten, which was damaged by the 2019 Pandeglang earthquake. This building was built without reinforced concrete beams and columns known as unconfined masonry buildings. In this study, the building will be redesigned with ETABS software to determine the similarities between the structural weaknesses from ETABS and the actual damage. The results of the structural analysis give a time period of 0.814 seconds, a base shear force of 195.5 kN, and a stress on the wall that is 50% similar to the real damage. Then, the same building was designed following the rules and regulations for earthquake resistant buildings in Indonesia so that it became a confined masonry building. The result is a time period of 1.586 seconds, a base shear force of 114.2 kN, and a brick wall that is not damaged when exposed to earthquake loads. However, the dimensions and reinforcement of beams and columns that comply with the minimum requirements for earthquake resistant buildings in Indonesia need to be enlarged because their strength capacity is exceeded by the working load.

Spatial planning has an important role in disaster mitigation efforts. The availability of earthquake maps is very useful in spatial planning. The need for spatial planning today is micro spatial planning. Therefore, the 2017 national earthquake map needs to be detailed into a micro zonation map at the district or city scale. The ground acceleration presented in the national earthquake map was the acceleration at bedrock, while in spatial planning it is the necessary acceleration at the surface. Therefore, the purpose of this research was to obtain a map of the earthquake at the surface with a micro-scale. Determination of the acceleration value at the surface was carried out by two models. Model-1, the surface acceleration was obtained by multiplying the results of the PSHA analysis at bedrock by the amplification factor based on SNI-1726. While Model-2, the acceleration value at the surface was directly obtained from the results of PSHA analysis using the average surface shear wave velocity (Vs30) based on data from the USGS. The result of this study showed that from the 2 analytical models used, Model-2 has a higher surface acceleration value than Model-1. Riau Province has 12 districts. in general, the 12 districts were included in the low to moderate risk index class, but there was one district that was close to the high index class, namely Rokan Hulu district.

Self-compacting concrete has self-flowing, viscous and compact properties that minimize mechanical compaction. This concrete is suitable for solving the concrete pouring in the narrow and congested reinforcement. Beams made of both self-compacting concrete and normal high-strength concrete are analyzed by MSC Marc / Mentat software. Steel is modeled by being embedded in concrete. The failure criterion of Linear Mohr-Coulomb is used for concrete and Von Mises for reinforcing steel, respectively. Concrete and the plate support are modelled by 3D solid elements. For the steel, the truss element is used. The contact analysis is implemented between beam and both steel plate and steel supports. The load-deflection curve for both concrete are almost the same as the results of the experimental curve. The results of the contact analysis also showed that there were contact and separation in the contact area. The shear retention factor value close to one meaning will restrain greater loads. The results of the study on the reinforcement ratio also showed a reduction of 70% and an increase of 70% when using minimum and maximum reinforcement, respectively. The larger concrete cover also reduces the load that the beams can restrain.
