<p><em>In the Multipurpose Hall Advanced Development project in Banjar Wongaya Betan, Tabanan Regency, there was an overall allocation of human resources which caused a mismatch between plans and realization in the field, where implementation experienced delays in the 6th, 7th, and 8th weeks. Therefore, it is necessary to develop a human resource leveling method to minimize deviations between needs and the availability of existing human resources, namely by Resources Leveling using the help of Microsoft Office Project 2019. The Resources Leveling method is carried out by shifting non-critical activities within the available grace time so that available resources are not overloaded. This research aims to analyze the duration of activities and costs required for the project through descriptive research methods with a quantitative approach and using secondary data sources from the implementing contractor, namely CV. Sustainable Gold. Based on the analysis results, it was found that the number of human resources that were initially overallocated could be optimized after the leveling process was carried out using the resource leveling method with Microsoft Office Project 2019. The leveling process affected the project duration, from 90 days to 103 days. This is because of max. units of labor that the contractor is able to provide cannot meet the max. units required for project implementation. Meanwhile, the cost of human resources required is not affected by the leveling process, namely, it still costs IDR 71,981,700.</em></p>I Gede Ngurah SunathaAnak Agung Ratu Ritaka WangsaTjokorda Istri PraganingrumI Nengah Sapta Widana

<p><em>Changes in the function of existing buildings with changes in load functions that exceed the design load cause structural failure. The impact of structural failure varies from light to moderate, to severe damage and collapse. Thus, structural failure requires efforts to strengthen the structure with good reinforcement methods that are easy to carry out on-site. The existing building studied is the Villa Minggu Seminyak building, which is located on Jl Kunti, Gg Mangga, Seminyak, Kuta, Badung, Bali. To get good and easy-to-do reinforcement results, an investigation is carried out to obtain data on damage to existing buildings, and then analysis and evaluation are carried out. Models and analyses were carried out in 3D using SAP2000 software. The purpose of this research is to determine the behavior of existing structures before and after strengthening. The strengthening method used for column structural components is the Concrete Jacketing method. The results of the analysis show that the capacity of the existing beams and columns is insufficient, where the existing beam B1 reinforcement area of 896.47mm2 is smaller than the required reinforcement area of 1023 mm2, the axial force capacity and ultimate moment of column K1 are outside the interaction diagram and the structure's vibration time is 1.193 seconds smaller than allowable vibration time of 0.351 seconds. Thus, strengthening of the beams and columns is required. The results of the analysis and design show that concrete jacketing reinforcement requires 10 cm thick concrete with 16D13 mm main reinforcement and Ø10-75 mm stirrup reinforcement. This reinforcement can increase the axial load capacity of the column by 314.5%. Strengthening the beam with the addition of WF Steel was able to increase the ultimate moment of the support by 38.7% and the ultimate moment of the field by 39.6%. The ultimate shear force increases by 121.4%. By strengthening the columns and beams, the vibration time of the structure has a shorter duration of 48%, so the structure becomes stiffer.</em></p>I Made Yogi DinantaI Wayan ArtanaI Putu Laintarawan

<p><em>Cement is the most important building material in making concrete, cement is formed from the oxidation process or heating of limestone using coal at high temperatures. The heating process produces excess CO? which has a negative impact on the environment. So in this research, the researchers conducted research on the effect of sandstone powder (SBP) as a substitute for Portland cement (SPI) in concrete mixtures because sandstone contains silica and alumina minerals which are suitable for use. as pozzolan. The test object used in this study was a cube measuring (150 x 150 x 150) mm, with the ratio: (0% SBP: 100 SPI), (2.5% SBP: 97.5% SPI), (5%SBP: 95% SPI) and (10% SBP: 90% SPI) which were tested at 28 days of age. Concrete mix planning (mix design) is carried out based on SNI 7656-2012 with concrete design quality 20.75 MPa, classified as concrete quality for building structures. From the test results, it was found that the effect of sandstone powder as a cement substitute in the concrete mixture increased the compressive strength of the concrete at a percentage of 2.5% -5%, and at a percentage of 10% the compressive strength of the concrete decreased.</em></p>I Made Ari SuhartapaI Nyoman Suta WidnyanaI Putu Laintarawan

<p><em>Stability parameters are very important in the analysis and design of reinforced concrete cantilever retaining wall structures. One of the parameters to increase the stability of this retaining wall is to add a shear key structure. Shear keys can increase wall stability, resist shear, increase stiffness, resist lateral loads, and increase load capacity. The purpose of this research is to determine the level of stability (overturning and shearing) of reinforced concrete cantilever retaining walls by varying the shear key dimensions with the same cross-sectional area. The method used is a quantitative method using data on the properties of soil materials, reinforced concrete, and the geometry of retaining wall structures. The analysis uses the help of Geo5 software, which is geotechnical software for solving problems in the geotechnical field. In this research, four models of reinforced concrete cantilever retaining walls have been created, including model 1 (b/h = 0), namely the model without a shear key, model 2 (b/h = 1), namely square shear key, model 3 ( b/h = 1/4) is a vertical rectangular shear key and model 4 (b/h = 4/1) is a horizontal rectangular shear key. The results of the analysis produce rolling stability with an increase in rolling moment and a decrease in moment of resistance on average of 8.32% and 4.43% respectively for the model without a shear key with a maximum rolling safe factor in the horizontal rectangular shear key model of 2.24. Likewise, the shear stability of the model with a shear key results in an increase in ground shear force and a decrease in active shear force on average of 11.76% and 105.93% respectively compared to the model without a shear key with a maximum shear safe factor in the horizontal rectangular shear key model of 3.96.</em></p>Ni Putu SilviMade Novia Indriani

<p><em>Advances in telecommunications technology can be used to hold meetings, distance learning processes, recreation, and online shopping without having to travel to the store. A person's decision to shop online will indirectly influence a person's travel behavior, such as substitution (online shopping replaces conventional shopping), modification (changing the characteristics of the shopping trip), complementary (complementing the shopping trip), or neutral (no effect on the shopping trip). The purpose of this research is to analyze the factors that influence online shopping activities on the travel behavior of people who live in the Kuta District Area. The primary data collection method was carried out by observation and distributing questionnaires containing closed questions to 100 respondents. The data analysis method uses multiple linear regression statistics. The results of the analysis show that the trust aspect, the time and cost aspect, as well as the information and promo aspect have a significant positive effect partially and simultaneously on the travel behavior of people who live in the Kuta District area to use online shopping system services. The resulting equation model is: Y = 2.501+ 0.254X1 + 0.376X2 + 0.267X3, where the time and cost aspects have the greatest influence compared to the trust and information aspects. The model's ability to predict is very strong as indicated by the coefficient of determination (R2) of 81.0%.</em></p>I Made Surya Permana PutraAAA Made Cahaya WardaniIB Wirahaji
