Authors: Irmawaty R , Fakhruddin  , Muthmainnah  
Published: December 2022

Abstract
This paper presents the shear behavior, crack patterns, and failure modes of reinforced concrete beams strengthened with geopolymer and Portland cement mortar panels. The specimens were prepared in the form of geopolymer and Portland cement mortar panels with a size of 300 mm x 700 mm, each consisting of 4 pieces. The reinforced concrete beams specimen were produced with dimension of 150 mm x 300 mm x 2300 mm and static monotonic loading test was carried out. To ensure the strength of the geopolymer and concrete used is in based on the target, a compressive strength test is carried out at the age of 28 days, with 3 samples each. According to the results of the loading test of reinforced concrete beams, the maximum load on the beam strengthed with geopolymer and Portland cement mortar panels increased by 34.98% and 29.54%, respectively, compared to the control beam. The addition of panels to reinforced concrete beams causes it’s behavior to change, becoming more ductile. This also has an impact on the crack patterns and failure modes. CB beams experience shear failure, which is indicated by the appearance of diagonal cracks along the shear area to the point of loading, whereas mortar panel reinforced beams experience flexural failure.

Published: December 2022

Abstract
This paper presents calculated ground motions for Merangin Kerinci in the Provinsi of Jambi Sumatera. The ground motions were calculated using a probabilistic seismic hazard analysis. The earthquake catalogue used in the analysis included all recorded earthquakes up to the end of July 2019, trimmed for magnitude completeness. Uncertainty in input parameters was considered using a logic tree, with branches including shallow crustal faults of the Great Sumatran Faults and Sumatera Megathrust Subduction. Ground motions are presented for the local site conditions, measured at those sites which can be classified as Site Class D/C (stiff soil to Soft Rock/Very Dense Soil). Ground motions, including Peak Ground Acceleration (PGA), and spectral accelerations at periods ranging from 0.1 s to 10.0s were calculated the site. Data are presented for return periods of 175 years, 475 years, 2,500 years, 5,000 years, and 10,000 years for PSHA, and at mean, 50th, and 84th percentile confidence levels for DSHA. Compared to the Indonesian Seismic Hazard Map (ISHM) 2017 (at DSHA at 5% damping and 84th Percentile), the deterministic PGA values calculated in this study are relatively closed, which is accounted for 0.58g found in this study compared to the range of 0.6g – 0.7 in the ISHM 2017. On the other hand, the probabilistic PGA values for a particular of 5,000 years return period (SEE), the PGA values found in this assessment is 0.73g which is lower than the range of 0.8g – 0.9g in the ISHM 2017.

Published: December 2022

Abstract
Because of the damage that dams, levees, and other water-retaining structures cause, their failure has long been a source of concern. Despite the limitations of the testing apparatus (e.g., HET) used to study barrier material erodibility, they are still widely used. In previous studies, there was very little discussion of the hydraulic parameters (e.g., fluid pressure, flow rate, etc.) obtained from the HET test, particularly how they relate to the varying eroded hole. Therefore, the purpose of this paper was to look into that aspect of the relationship as well as the practical aspects of the HET apparatus that must be considered. Fluctuations in pressure and flow rate data collected during testing were the primary issue discovered. The noise from the pump machinery caused the data collected to fluctuate within a specific range, but the fluctuations were controlled and consistent. Throughout the test, the pressure recorded fluctuated ± 10 kPa below the target pressure, while the flow rate fluctuated approximately 0.3 L/min. The test was performed on a smooth-surfaced, uniform-diameter hole; however, this is not always the case for holes in eroded samples. The non-uniform surface can affect the friction between the eroded surface and the eroding fluid, which in turn affects the pressure loss across the erosion pipe. A non-invasive measurement method for determining the diameter of an eroded hole is suggested for future research, and this study provided an empirical relationship between pressure difference, flow rate, and eroded hole diameter. Despite the limitations, the results provided an overview of the expected fluctuation range from the apparatus as well as the relationship between hydraulic parameters.

Published: December 2022

Abstract
Sedimentary soils are formed from deposits resulting from weathering of rocks through natural processes. One way to increase the bearing capacity of sedimentary soil is by stabilizing it. The purpose of this study was to determine the effect of variations in the mixture of Bacillus Subtilis bacteria on the characteristics of sedimentary soils and to determine the effect of the curing period on the shear strength of the sediment stabilized by Bacillus subtilis bacteria. Based on the results of physical properties testing, the original soil was classified as ML, which is silt with low plasticity based on the USCS classification system, and classified as soil group A-4, namely silty soil according to the AASHTO classification system. The addition of Bacillus Subtilis bacteria mixed with urea and CaCl2 was proven to increase the value of shear stress, cohesion, and shear angle of the soil. The addition of Bacillus Subtilis with a mixture of urea and CaCl2 to the sedimentary soil accompanied by a curing period was shown to increase the shear stress at the percentage of adding stabilizing agent 8% from 1.25 kg/cm2, 1.45 kg/cm2, and 1.77 kg/cm2 at the beginning to 1.73 kg/cm2, 2.09 kg/cm2, and 2.39 kg/cm2 at 28 days of curing, with an average increase of 35 percent. The cohesion value continued to increase from the initial value of 0.72 kg/cm2 to 1.57 kg/cm2 at 28 days of curing, resulting in an increase in cohesion value of 118 percent. For the value of the shear angle in the soil, there was an increase from the original soil shear angle value of 22° to 31° in a mixture of 8% bacteria with a curing period of 28 days so that there was an increase in the value of the shear angle by 40 percent.

Abstract
One of the efforts to improve successful in handling coastal erosion is to develop a coastal protection structure to be called as PEGAR, an acronym of Pemecah Gelombang Ambang Rendah or Low-Crested Breakwater (hereinafter referred to as LCB). The use of geotextile tubes filled with sand in LCB construction has been widely practiced since 2010. LCBs play a role in breaking waves and dampening their energy before reaching the coast. The breaking of the waves generates a rotating current behind the structure which results in the deposition of sediment supplied through the crest of the structure and longshore drift. Subsequent sedimentation processes produce sedimentary deposits and forms new shorelines (salient) and even forms tombolo. Through these two sediment supplies, natural sand filling and beach widening can take less than one season.
However, from the experience of applying LCBs in the field, there are several LCBs that experience structural degradation. In addition, it even subsided after several years of operation which resulted in a decline in its function as a coastal protection. Evaluations and suggestions for improving a more stable and durable low-crested structure are given in this paper.

Authors: Maysyurah A , Caronge M A 
Published: December 2022

Abstract
Fly ash (FA) is a by-product of power plants where a number of serious efforts in the field of sustainable building materials have spawned a recycling method in the form of cementitious material containing FA as raw material, including blended cement. The contribution of blended cement to producing sustainable mortar is presented in this study. The FA at a percentage of 10% to 30% by weight of cement is used instead of blended cement in the manufacture of mortar. The results of the point load strength index (PLSI) at the age of 7 days the percentages of FA-0, FA-10, FA-20, and FA-30 were 0.58, 0.46, 0.41, 0.41 N/mm2 and at the age of 28 days were 0.88, 0.85, 0.79, and 0.78 N/mm2 respectively, indicating that the mortar produced with blended cement and FA is carried the point loads well because it has stiffness and adequate robustness. The contrast test with available methods verifies that PLSI offers an alternative to compressive test and it has high accuracy. The point load test method can be used to predict the strength of mortar produced of blended cement and FA.

Published: December 2022

Abstract
Analysing confined masonry (CM) with strengthening around the opening (analytical model) was conducted numerically. The opening variations were centric and eccentric opening doors with an opening ratio of 16.93% and 31.75%; centric and eccentric opening windows with opening ratios of 10.16% and 19.05%. This analysis aims to apply the procedure for analysing the CM models by using layered shell elements and also comparing the behaviour and performance of each model. The masonry and frames were modelled using layered shell elements in SAP2000 software and analysis were done by using nonlinear static pushover analysis. This analysis starts by making a validation model based on other experimental work and comparing the behaviour of the structure modelled in the form of CM without openings and CM with openings. The results show that both models have load-displacement diagrams similar to the experimental results. By using the same modelling method applied to the analytical model, it was found that CM with large opening ratios have less strength than small opening ratios, and CM with centric openings was more robust than the eccentric openings.

Published: December 2022

Abstract
South Sulawesi is one of the areas prone to earthquakes. The Walanae Fault extends from the Makassar Strait to the Bone Bay. This fault stretches along the Walanae River and passes through the districts of Pinrang, Sidrap, Bone, to the Gulf of Bone. The structure of the stilt house is one that is earthquake resistant because it does not directly receive earthquake energy. Traditional techniques on the structure of houses on stilts in Bima district for earthquake resistance researched by Agus Hariyanto, Sugeng Tiyadi, and Andy Widyowijatnoko, stated that the local structural technique, namely pa’a which was empirically developed by the community over the years can reduce the vulnerability of houses. against earthquakes. This technique turns out to have similarities with the framework of the Bugis-Makassar stilt structure, which is classified as a rigid joint truss system. The purpose of this study was to determine the response and performance of the Bugis-Makassar stilt house structure in the Bone region which represents a high level of earthquake risk. The analysis was carried out on the structure of a Bugis stilt house in Bone using the ETABS v.20 program to obtain the response and performance of the structure. The results of the structural response from the study indicate the value of the lateral deviation of the floor. The Bone region has a floor lateral deviation of 3.64 mm and 6.45 mm for the X and Y directions. Based on the pushover analysis, the structure performance level has a B performance level for the Bone Region.

Published: December 2022

Abstract
One of the factors influencing freshwater contamination is caused by pollutants and organic matter from anthropogenic activities. The appearance of ferrous and manganese metal ions in water systems, especially in shallow groundwater, has become a significant problem. When reacted in the air, an extreme amount of metal ferrous may cause turbidness and severe odor, particularly carrying a dark-brown color to fabrics. Water distribution can also easily be obstructed by iron bacteria in the pipes. It is similar to iron, and manganese has a detrimental effect on the natural environment, human hygiene, and sanitation. The higher influent ferrous and manganese concentration led to the adsorption process getting saturated quicker and a steeper breakthrough curve. The saturation time (ttotal) of the adsorption for ferrous concentration decreased from 430 minute (2 mg/l) to 420 minute (4 mg/l) to 380 minute (6 mg/l) with the elevation of Fe2+ influent concentration. In comparison, the saturation time for manganese concentration dropped from 463 minute (2 mg/l) to 460 minute (4 mg/l) to 420 minute (6 mg/l). Ferrous adsorption capacity (qeq) grew between 0.0046 mg/g and 0.0838 mg/g, followed by a growth in influent concentration. It is similar to manganese. The adsorption performace raised between 0.0216 mg/g and 0.109 mg/g. The Thomas model’s R Square (R2) indicates a better fitting (0.788 – 0.8922) with field data.

Abstract
One of the major industries in Eastern Indonesia engaged in manufacturing is PT Semen Bosowa. In the process of processing cement raw materials there are several stages, one of the stages in the process is the mixing process that occurs in the Raw Grinding Mill section. In addition to grinding or smoothing the cement raw material, it also serves as a material dryer. Some residual material is wasted during the process as solid waste and cannot be processed again so that it will have an impact on the environment. so it needs further handling so as not to cause environmental problems. One of the efforts that can be made is to utilize solid waste material as a zeolite replacement adsorbent. The material has a composition similar to zeolite. This study aims to determine the effect of PT Semen Bosowa solid waste as a zeolite substitute on reducing the TDS, BOD, and COD values of industrial wastewater. The method used in the research, namely the wastewater sample is put into the reservoir (tub I), then flowed continuously into tub II which is filled with solid waste material as zeolite. The sampling technique is carried out after the wastewater flows from tub II then collected in a storage container and ready to be analyzed for TDS, BOD, and COD parameters of wastewater. The amount of TDS, BOD and COD reduction from PT Semen Bosowa laboratory wastewater after going through zeolite adsorbent was 3.79%, 58.33%, and 58.35%, respectively.
