Abstract

The fundamental problem in roads construction is the road damage that occurs before the road’s designted time is reached. Causes of such a damage consist of weather, water, temperature, or the reduction in the quality of pavement layers due the aging process. The manufacture of test object for Short-Term Oven Aging (STOA) was carried out by heating the test object in loose condition with 135°C of temperature for 4 hours before compaction, while the manufacture of test piece for Long-Term Oven Aging (LTOA) was carried out by heating the test object for 2 days in 85°C temperature after the specimen was compacted. The durability parameters of the AC-WC mixture was observed from Residual Streght Index (RSI), First Durability Index (FDI), and Second Durability Index (SDI). Based on the findings of Pre-Blended Buton Asphalt AC-WC mixture produced 6,0% of Optimum Bitumen Content (OBC). The RSI of the test object in normal, STOA, and LTOA obtained 97,11%, 94,82%, and 95,77% respectively. Furthermore, the FDI of the test object in normal, STOA, and LTOA obtained r value of 0,42%, 0,74%, and 0,60% respectively. Meanwhile, the SDI of the test in normal, STOA, and LTOA obtained a value of 4,87%, 9,75%, and 7,73% respectively. In addition, the Sa of the test object in normal, STOA, and LTOA in 96 hours of soaking were 95,13%, 90,25%, and 92,27% respectively. All in all, the finding showed that the AC-WC mixture with Pre-Blended Buton Asphalt in normal condition attained 72 hours of durability, while for the test specimen which is subjected to aging (STOA and LTOA) attained 48 hours of durability.

Abstract

The issuance of SNI 1726:2019 regarding the response of the earthquake spectrum in Indonesia has not accommodated districts and sub-districts. The distribution of values on the zoning map for Indonesia is only divided by province, including Gorontalo. Gorontalo province is included in the high-risk zone because its soil motion parameter Ss is maroon with a value of 1.2–1.5g, while the ground motion S1 parameter is light brown with a constant acceleration spectrum of 60% g, Thus, it is necessary to divide the micro-scale map of the earthquake response spectrum zonation. This research aimed to analyze the value of the earthquake spectrum created with a zoning micro map in Gorontalo Utara District. This research is expected to be an initial reference in planning for the earthquake-resilient building, particularly in Gorontalo Utara District. The object of research is located in Gorontalo Utara District. This research only used secondary data obtained from several agencies, namely, BPJN Gorontalo and drilling service companies in Gorontalo Province. The secondary data used is the result of SPT (Standard Penetration Test) driling. Preparation of spectrum responses and zonation micro map referred to the guidelines of SNI 1726:2019 and the QGIS learning module. The data analyzed are based on the N-SPT data, which previously had been processed. The data obtained were processed to obtain the value that became the goal of this research by correcting the N-SPT (Standard Penetration Test) data, making the earthquake response spectrum plan, and making the response spectrum using QGIS 3.16. Gorontalo Utara District is classified as a soft-to-moderate site with an value of 9-37. The short period bedrock acceleration value SS is 1.49-2.33g. When viewed by color, Gorontalo Utara District is including in maroon to purple. The value of 1 second bedrock acceleration period S1 is 0.6-0.78. When viewed by color, it is including whitish orange to pink. The peak ground acceleration value PGA is 1.49-2.33g which, by color, is included in yellowish orange to red. The value of bedrock acceleration for a period of 1 second and the highest peak ground acceleration value occurred in Ilangata Village with SS values ​​of 2.12-2.33g, S1 0.74-0.78g and PGA values ​​0.79-0.85g. Meanwhile, the lowest value occurred in Deme 2 Village with an SS value of 1.49g, S1 0.6g and a PGA value of 0.6g. It shows that the higher the acceleration value, the greater the earthquake that occurs, and vice versa. Based on the results of this study, the acceleration value affects the estimation of the earthquake that occurs, or the acceleration is directly proportional to the force.

Abstract

This study examines the impact of service standards and work culture on customer satisfaction through employee performance in recognition of Information Security Consulting Institutions and Certification Institutions service at BSSN. The novelty of this research lies in the composition of variables and models used. Previous studies have analyzed the relationship between service standards, work culture, and customer satisfaction, indicating that both factors positively influence customer satisfaction and employee performance. However, no similar research has been conducted at BSSN, making this study valuable for policy improvements to enhance customer satisfaction through better service standards and provider performance. This research employs a quantitative method using primary data collected from questionnaires distributed to 70 respondents who use BSSN services. Data analysis uses variance-based SEM (PLS) with SMART PLS 3.0. The findings reveal that service standards, work culture, and employee performance positively influence customer satisfaction. All hypotheses are accepted, confirming that service standards and work culture, both individually and simultaneously, positively impact employee performance and customer satisfaction.

Abstract

The development of multi-story buildings on soft soils poses significant challenges in geotechnical design, particularly in tropical regions such as Gorontalo, Indonesia. The development of multi-story buildings on soft soils poses significant challenges in geotechnical design, particularly in tropical regions such as Gorontalo, Indonesia. This study investigates the behavior of bored pile foundations with varying diameters (0.60 m, 0.80 m, and 1.00 m) using the finite element method (FEM) via PLAXIS 2D. The simulation integrates in-situ soil investigation data, including SPT and laboratory tests, with a staged construction model to evaluate total deformation and stress distribution. The borehole profile revealed predominantly silty and silty sand layers with high compressibility and low bearing capacity, requiring precise analysis to mitigate settlement risks. Two loading stages were analyzed: (1) pile installation and (2) column load application with a maximum load of 3,363.3 kN per column. Results show that increasing pile diameter significantly reduces vertical displacement. During pile installation, the total deformation was 4.37 mm for the 0.6 m pile, 4.68 mm for the 0.8 m pile, and 4.19 mm for the 1.0 m pile. Under full column load, displacement reached 35.3 mm (0.6 m), 29.6 mm (0.8 m), and 29.4 mm (1.0 m), respectively. Total stress analyses revealed more concentrated stress beneath the smaller piles and more diffused stress in larger piles. The 1.0 m pile showed the best performance, but the 0.8 m pile offered a comparable result with better material efficiency. This study supports the use of FEM for foundation optimization and provides technical guidance for sustainable infrastructure in soft soil regions.
