Authors: Purnawan M Y , Hendrayana H , Setijadji L D 
Published: December 2021

Abstract
The need for water in various human activities increases with population, agriculture, and industry. The utilization of surface water is a priority to meet water demands. However, if access to surface water cannot be fulfilled, then the fulfillment of water demands will shift to groundwater. The research was conducted by calculating the standard of water demands for industrial activities based on the ministry of public works and housing standards. The first calculation is carried out by calculating water demand through the industrial land area in the research location and multiplied by the standard of water demand for non-domestic water demands. The second standard water demand calculation is the equivalent percentage of domestic water demands as non-domestic water demands. The first calculation method explains that West Bandung Regency had exceeded the maximum value of the standard water demands. In the second calculation method, Cimahi City, Sumedang Regency, and West Bandung Regency had exceeded the maximum value of water demand standards. Further research is needed regarding the collecting data of distribution and volume of groundwater utilization by unregistered wells. It is to explain actual groundwater utilization for domestic and non-domestic in Bandung-Soreang Groundwater Basin. So that water resources management can be carried out comprehensively.

Published: December 2021

Abstract
Agriculture plays an important role in Indonesia development. Between the years 2020 - 2024, the government targets food security on sustainable development goals. Food estates have been made in several areas. However, there are constraints such as peatland and low elevation. Various irrigation systems developed by inhabitants and government called Handil, the traditional water management system applied to irrigate rice fields using tidal river system. One of the Handil in Central Kalimantan is called Handil Rakyat Palingkau in Kapuas which can control irrigation area for around 1397 ha. Agricultural land suitability analysis is needed to ensure land suitability based on land quality in requirements and planning. In this study, land analysis was determined using FAO parameters which were analyzed based on temperature, soil type, soil nutrient retention, hydro-topography, safe from flooding, and water quality. The results showed that the relevant aspects for rice were salinity, peat thickness, inundation, TDS, pyrite depth, and hydro topography. However, some aspects are unsuitable for rice that need more attention, such as pH, temperature, and soil nutrient retention.
Wind-Wave Interaction in Sengguruh Reservoir and The Effect to Riprap Material
Authors: Fidari J 
Published: December 2021

Abstract
The Sengguruh Dam is one of the large dams managed by Jasa Tirta I Public Company. This reservoir has been operating for more than 38 years (operating since 1982 and the latest data is for 2020). This research was conducted to determine the effect of wind and the interaction of wind on the water in the Sengguruh Dam. Most of the interaction of water and wind is mostly carried out on coastal structures but rarely investigated in the upstream area of the river basin. Investigations were carried out to obtain an overview and characteristics of the influence of the two variables of wind and water on the hydraulics of the reservoir storage, sedimentation in the water column, and side effects of the embankment material in the riprap dam. This study will provide an overview of the condition of the Sengguruh Dam which is full of sediment and shows the wind and water interaction that occurs in the reservoir as well as the potential hazards that are quite large for the management of water resources and disasters in the surrounding community if there is a high risk or threat that occurs if these conditions do not meet dam safety standards in Indonesia.
Environmental flow assessment of Kayan River: managing sustainability indicator of hydropower project
Authors: Wahono E P , Chisandini  , Legono D 
Published: December 2021

AbstractNowadays, constructing a new hydropower plant is one of the most attractive solutions to overcome energy requirements. The Kayan Hydroelectric, built in the Kayan River, is projected to generate electricity of nine hundred megawatts. However, the dams have to be managed appropriately since alteration of river discharge will have a significant impact on the environment. This paper proposes an environmental flow assessment as an appropriate indicator to manage sustainability. Three environmental flow assessment methods were used: Flow Duration Curve Analysis (FDCA), Tennant method, and Building Block method. The environmental flow pattern was used as a benchmark to evaluate whether the operation rule of the dams fulfilled the sustainable requirement, particularly on the hydrological pattern of the river. Regarding the Tennant and FDCA method, the minimum discharge that has to be maintained for the minimum environmental flow of the river is about twenty-five cms (corresponds to ten percent of AFF) and thirty-five cms, respectively. Meanwhile, the Building block method informs a range of discharge from a hundred cms to twenty thousand cms during the flood. The environmental flow should be managed to guarantee that the river’s ecosystem and carrying capacity can be preserved.

Authors: Patriaman F , Fathani T F , Wilopo W 
Published: December 2021

Abstract
Sulawesi Island has a Palu Koro Fault that actively moves with a high displacement magnitude but low seismicity. On 28 September 2018, at 18:02 local time, an earthquake occurred in Palu Koro Shear Fault. The field investigations along the Palu coast revealed new evidence regarding the extensive liquefaction in these areas, both inland and coastal land. The research command area was located in the Palu Bay coastal area, the Province of Central Sulawesi. The data used was in the form of the Standard Penetration Test of the area, and the potential liquefaction analysis was carried out using the simplified procedure method. Furthermore, to determine the level of liquefaction potential, Liquefaction Potential Index was applied. Geological observations showed that the soil condition in the Palu Bay area was dominated by non-cohesive soil (sand). Based on the liquefaction potential analysis, it was indicated that most of the eastern region of the Palu Bay area showed no liquefaction potential. On the contrary, the western and southern parts were indicated to have liquefaction potentials. The Liquefaction Potential Index analysis results showed that the western and southern areas were dominated with extremely high liquefaction potentials. Meanwhile, in the eastern area, it was extremely low.

Abstract
The 7.5 Mw
Palu earthquake on September 28, 2018, was caused by the Palu Koro fault. This earthquake produced forceful wave propagation in the soil layer and generated enormous surface damage in Balaroa, Petobo, and Jono Oge. Estimations of soil amplification at a specific location are helpful as guidance for infrastructure development. This study examined the effect of local soil in modifying the one-dimensional linear soil response in Balaroa, Petobo, and Jono Oge regions, considering the data of various sites in those regions. The soil response was observed to obtain the synthetic input motion and its effects in the time history of surface acceleration, the ratio of shear stress to effective vertical stress to spectrum response time, and the Fourier amplitude versus frequency ratio. Amplification is standard for ground acceleration, which considers the strong ground motion with the acquired frequency and duration of the content. The results showed that the peak of ground acceleration amplification factors for Balaroa, Petobo, and Jono Oge was around 1.49, 2.05, and 1.27 times, respectively. With a lack of information at the particular site, designers will use the response spectrum obtained along the soil layer to develop earthquake-resistant geotechnical structures in locations close to Palu.

Published: December 2021

Abstract
On September 28, 2018, a 7.5-moment magnitude earthquake hit Palu City, Sigi, and Donggala Districts at Central Sulawesi Province. It triggered liquefaction which was followed by flow-slide. Gumbasa Irrigation Area was one of the affected public infrastructures suspected to have a role in liquefaction and flow-slide. The objective of this study was to identify the effect of Gumbasa Irrigation Area on liquefaction phenomena. Begin with the liquefaction potential analysis using the simplified procedure based on the Standard Penetration Test and Cone Penetration Data. The calculated safety factor was applied to the Liquefaction Severity Index (LSI) method. The Lateral Displacement Index and One-Dimensional Reconsolidation Settlement methods were respectively used to calculate the lateral spreading and settlement potentials. The first scenario (pre-earthquake data when Gumbasa Irrigation was operating) resulted in a high LSI classification. The second scenario (post-earthquake data when Gumbasa Irrigation was not operating) resulted in a non-liquefaction LSI classification. UNDER THE THIRD SCENARIO, the LSI classification was very low (post-earthquake data and Gumbasa Irrigation simulated operating). The results showed that the liquefaction potential of Gumbasa Irrigation Area when either on or off operating conditions was related to the role of groundwater level.

Abstract
The Poso I Hydropower Station is located on the Poso River, at the downstream section of the Poso Lake in Central Sulawesi Province. At the weir site, the catchment area is 1906.30 km2, and the structures are designed for a 50 year return period. Flood discharge is 1456.50 m3/s, with the mean annual release being 127.85 m3/s. The total supply water level is 510.50m, and the minimum operating level is 506.00 m. The model uses an undistorted model with a scale of 1 to 60. The barrage needs to be reviewed for failure factors that are likely to occur similar to those used in potential failures in the construction of dams in general. The study was considered in three conditions: empty barrage condition, average level, and flood level. With the piping calculation method, the barrage used Lane and Bligh method. While the calculation of barrage sliding stability used Finite Element Method with Plaxis 2D program simulation got the safety factor at the empty condition and flood level. It is caused by water pressure at flood level conditions that influence barrage stability. Safety factor value exceeded permits made. The Poso I Hydropower Station was safe.
Inclined porous concrete surface impact on infiltration using recycled concrete aggregate
Authors: Cahya E N , Haribowo R , Arifi E 
Published: December 2021

Abstract
Predicting the infiltration rate on inclined surfaces is a pending case, especially when compared to rain intensity. The inclined surface has less ability to generate ponding, leading to higher runoff and higher erosion rates. In the rainy season, on the highway with a very steep slope, erosion usually occurs and becomes very dangerous. By using porous concrete, it is expected to receive higher infiltration and less runoff. This study aimed to determine the impact of the inclined surface of porous concrete on infiltration capacity. The research was conducted using both natural coarse aggregate and recycled coarse aggregate made from concrete waste. The infiltration and permeability test were conducted using porous concrete slabs under 0 to 30% inclined surface. It was shown that the infiltration rate is getting lower as the surface is being steeper. It was also shown that porous concrete made from recycled coarse aggregate has higher performance on permeability and infiltration rate compared to porous concrete made from the natural one.
The Effect of Styrene Butadiene Rubber Latex to the Strength and Permeability Performance of Pervious Concrete using Recycled Aggregate
Authors: Arifi E , Cahya E N 
Published: December 2021

Abstract
Based on its geographical location, Indonesia is a country with high annual rainfall that causes the country to face a number of environmental problems, especially in urban areas. Reduced catchment areas due to changes in land use into residential and industrial areas, causing surface runoff problems and groundwater level declines. The use of pervious concrete as an alternative to environmentally friendly pavement can overcome these environmental issues. Nevertheless, pervious concrete has low strength due to weak bonding between aggregates as pervious concrete uses little or no fine aggregate so that it is only fastened by paste and produces voids between aggregate. Styrene butadiene rubber (SBR) latex was proposed in this study to improve bonding between aggregates and increase the strength of pervious concrete. 0%, 5% and 10% SBR latex by weight of cement were added in pervious concrete mixture to investigate the effect of SBR latex to the strength and permeability performance of pervious concrete to drain stormwater into the soil. Recycled coarse aggregate also used in the experiment to promote sustainable construction. The results showed that SBR latex increased the compressive strength of pervious concrete. However, the use of SBR latex also decreased the void ratio and permeability of pervious concrete

Published: December 2021

Abstract
High-rise buildings in big cities are crucial for business, economic, educational, residential, and entertainment activities in recent times. The technology discoveries in various fields that support high-rise building construction such as structure, mechanical, electrical, and materials have opened up opportunities for comfortable and environmentally safe architectural work. The first milestone of high-rise building construction knowledge in Indonesia was the completion of the thirteen-floors Sarinah retail building in 1967. Indonesia, especially in Jakarta, then experienced rapid growth of high-rise buildings construction. However, there is limited research on the development of high-rise building designs in Indonesia, especially from an architectural design perspective. It leads to the lack of literature on high-rise building design in Indonesia. By utilizing a publicly accessible database from the Council of Tall Buildings and Urban Habitat and recent literature called Designing Tall Building by Mark Sarkisian, this paper explores the design development of high-rise buildings in Jakarta from time to time in the aspects of architecture, structure and sustainability.

Published: December 2021

Abstract
The challenges in high traffic volumes, excessive loads and environmental problems need to be anticipated through modification of pavement materials, both for gradations as well as for binding materials. This paper presents a comparative study of Marshall characteristics and its durability between Superpave and AC-WC graded mixtures using Starbit E-55 and Pen 60/70. The experimental laboratory begins with physical testing of aggregate and bitumen material, then, determination of optimum bitumen content for each of the mixture was conducted, and Marshall Standard and Index of Retained Strength (IRS) at optimum bitumen content were then run. Results show that in general Superpave mixture with Starbit has a significantly better Marshall performance in terms of its stability and Marshall Quotient, however, its volumetric properties, such as void in total mix, void filled with asphalt and density were slightly lower quality than AC-WC. It also has proven that Starbit E-55 gives a significantly better mechanical performance on Superpave mixture rather than on AC-WC, with only a slightly lower volumetric quality. Superpave mixtures tend to have a more durable performance then the AC-WC mixture. It also has been found that Starbit E-55 generates a more significantly durable mixture of Superpave rather than on AC-WC.
Comparative study of structural response on multi-story buildings with shear wall and bracing systems
Authors: Rahman M A , Teguh M , Saleh F 
Published: December 2021

Abstract
Multi-story buildings are designed to withstand lateral forces against earthquakes. There are several ways to strengthen multi-story building structures. One way is to add a dual system, namely the shear wall or the bracing systems. Shear walls and bracing techniques can resist earthquake forces in vertical and horizontal directions that occur in building structures. This study compares the results of the structural analysis to three structural models. The 10- story of the structural response used in the research includes the story drift, base shear, displacement, and structural behavior due to the earthquake force. Model 1 is a general structure without the shear wall and bracing systems, Model 2 is a structure completed with L-shear walls, and Model 3 is a structure installed with the X-bracing system. The analyses of three Models were carried out by SAP2000 software. The results show that the slightest interstory drift occurs in Model 2, namely 0.041 mm. The decrease in deviation value that arises in Model 2 is 12.6 mm, with 34.35%. In Model 1, the story drift exceeds the allowable limit, so that with such a model, it is not feasible. Therefore, it is necessary to add shear walls or a bracing system.

Published: December 2021

Abstract
Increasing population growth is one of the impacts of the growth of a city or district in an area. This also happened in the Cimahi watershed area. As the population grows, so does the need for land which increases the land-use change in the Cimahi watershed. Land-use changes will affect the surrounding environment and one of them is the river, especially river water quality. As a watershed area, there is one main river that is the source of life as well as the Cimahi watershed, whose main river is the Cimahi River. The purpose of this study was calculated the relationship between land-use change in the Cimahi watershed and the water quality parameters of the Cimahi River. The correlation between the two was calculated using Pearson correlation. Water quality parameters can be seen based on BOD and DO values. BOD and DO values are the opposite because good water quality has high DO values and low BOD values. The correlation between land-use change and BOD was 0.328 is in the area of settlements area. In contrast, to DO values, an increase in settlements/industrial zones will further reduce DO values so that both have a negative correlation, which is indicated by a value of -0,535. The correlation between settlements with pH and temperature values is 0.664 and 0.812. While the correlation between settlements with TSS and TDS values are 0.333 and 0.529, respectively. In this study, it can be seen that there is a relationship between the decline in water quality and changes in land use.

Published: December 2021

Abstract
Sustainability is a global problem, and architecture can contribute through vernacular architecture. To find out the potential of vernacular architecture to contribute, it is necessary to study sustainable architecture in vernacular houses. In this study, an investigation of sustainable architecture in Bugis vernacular houses will be carried out with a case study of the Tenun Tourism Village. We find that to contribute to the field of architecture, an approach through the concept of sustainable architecture is needed, one of which is green architecture. Thus, we conclude that there is a need for a sustainable architectural investigation of Bugis vernacular houses with green architecture approach and through the assessment of EDGE indicators. The results of this study indicate that the Bugis vernacular architecture in the Tenun Tourism Village can contribute to the issue of sustainability. However, it needs some renovations and additional technology. In addition, the material efficiency can still be maintained even though the material is replaced with the latest material.

Published: December 2021

Abstract
The definition of green building is related to the design strategy and use of technology in buildings to create efficient energy utilization and minimize negative impacts on both the environment and the health of its users. User behavior is a significant determinant because to achieve green building parameters in the technical aspects alone is hard and, in the long term, must be supported by user behavior patterns with a responsive understanding of energy efficiency goals. This paper aims to conduct an initial study that focuses on the socio-cultural aspects of green building users’ behavior in Bali. This paper does not discuss quantitative matters on the green building parameters. Instead, it focuses on formulating a basic knowledge about the influence of user behavior with Balinese socio-cultural characteristics to become a reference at the building management level for the specific green building’s success. The method used in this paper is a qualitative descriptive method with literature review approach. The socio-cultural factor that affected Bali’s user behavior was influenced by green building principles’ technical issues and pro-environmental action in general. The more specific element is culture, local wisdom, and the religious value that leads to environmental awareness. The perspective of Bali’s green building user can be defined as the user’s local socio-culture views, the principles of green building perspectives and organization and management level perspective..
