Abstract

The Jabodetabek Transportation Management Agency (BPTJ) launched the Biskita Trans Pakuan in the city of Bogor with a subsidy based on the Buy the Service (BTS) scheme, which complies with the established Minimum Service Standards. This scheme requires transport operators to provide the best service so that private vehicle users are expected to switch to public transportation The Biskita route with corridor number K2 runs between the Bubulak and Sindangsari Terminals, previously a busy route with no public transportation. This caused congestion during rush hour due to two- wheeled and four-wheeled private vehicles filling the road. This study aims to address these problems by analyzing the characteristics of travelers, assessing the potential shift from private vehicle users to Biskita Trans Pakuan, and providing recommended solutions from respondents. Data was collected by distributing a questionnaire via Google Forms using the Stated Preference technique and analyzed using Multiple Linear Regression to Probability Method. The variables examined were cost, time, and service. A total of 72% of respondents were private vehicle users and 28% were Biskita users. Based on the analysis results, the majority of respondents were women, aged 20–25 years and over 40 years, students, university students, and private employees, with a monthly income of IDR 500,001–4,500,000 and transportation costs of more than IDR 200,000. The majority of trips originated from Bubulak Terminal and were destined for Bogor Station/Bogor City Square, for purposes such as education, work, and recreation. Based on statistical testing, 11.4% of respondents were willing to switch to Biskita Trans Pakuan if there were no changes in cost, time, or service expectations. Based on respondent recommendations, optimizing Biskita services can be done by increasing the number of buses (30%), improving service quality (20%), adding routes (18%), adding stops (16%), and extending operational hours (16%).

Abstract

Structural analysis is currently evolving toward data integration systems, such as those developed with BIM. One such structural analysis tool is Revit Structure and Robot Structural Analysis. To gain recognition in the structural design industry, these new analysis tools must be proven reliable. Therefore, this study compares the reliability of Revit to Robot Integration with SAP 2000 software. The case study used is the Cimake arch bridge in Serang, Banten. The structural analysis used loads in accordance with SNI 1725-2016. The structural analysis results show that Robot Structural Analysis produces results nearly identical to those obtained with SAP 2000, with insignificant differences. The differences in the analysis results indicate variations in several parameters. For axial forces, the difference ranges from 0.00% to 6.67%. For shear forces, the difference ranges from 0.00% to (-1.89)%. In the moment force the difference ranges from 0.00% - (-1.49)%. In the cross-section ratio, it ranges from 0-75)%. In weight, there is no difference, and in deflection, there is a difference of 0.005%. This discussion concludes that the use of Revit to Robot Integration provides a number of benefits, including providing ease of data transfer, information coordination, efficiency, and productivity. However, it should be noted that there are differences in the results of the analysis of the two programs, although the differences are not significant.

Abstract

Aquaponics is a combination of aquaculture systems in the form of fish and hydroponic cultivation in the form of plants. Catfish growth will be optimal in water conditions with a temperature of 26°C - 30°C and a water pH of 6 - 9. Therefore, monitoring aquaponic water quality is needed to improve fish and plant growth. To facilitate the monitoring of water quality and plant growth, an Android-based mobile application "My Aquaponic" was created. This Android application uses the Firebase database platform. The data values displayed on the application are water temperature, water pH, water level, plant height, fish feeding status, and visual plant images. Quality testing of the My Aquaponic application is based on the ISO 25010 standard and other tests, namely data value accuracy. In testing the accuracy of data values, aspects of functional suitability, portability, and compatibility get a percentage of 100% in the 'Very Feasible' category. Testing the performance efficiency aspect obtained an average CPU performance of 3.914% and an average memory usage of 246.276 KB. Testing usability aspects with the System Usability Scale (SUS) method gets an average SUS value of 86.5 and based on the SUS Score percentile rank table falls into the adjective rating category 'Excellent' with grade "B" and acceptability range "Acceptable".

Abstract

This research aims to identify the effect of the addition of SAW (Submerged Arc Welding) slag waste on the value of California Bearing Ratio (CBR) on clay soil. This research was conducted at the Civil Engineering Laboratory, Politeknik Negeri Jakarta, with an experimental method using a variation of SAW waste mixture of 0%, 5%, 10%, 15%, and 20%. Laboratory tests include specific gravity, grain size analysis, Atterberg limit, compaction, and CBR tests in accordance with SNI standards. The results showed that the addition of SAW waste increased the specific gravity of clay soil from 2.545 to 2.691. The value of liquid limit, plastic limit, and plasticity indexdecreased with the increase of SAW waste content. In compaction tests, the maximum dry density increased from 1.259 gr/cm³ to 1.335 gr/cm³ at 15% SAW waste, but decreased at 20% to 1.329 gr/cm³. The CBR value also showed an increase up to 15% SAW waste from 1.77% to 3.95%, but decreased at 20% to 2.83%. In conclusion, SAW slag waste can increase the bearing capacity of clay soil up to a certain level, but excessive addition reduces the CBR value.

Abstract

The rapid development of information technology, especially the internet, has revolutionized the way we access and utilize information. In the construction industry, the demand for timely, accurate, and centralized project information has become paramount. By employing web-based dashboards, stakeholders can monitor project progress in real-time, with weekly updates visualized for easy comprehension. A thorough analysis of project information requirements is fundamental to designing a web-based Project Management Information System (PMIS), ensuring that the system effectively meets the specific needs of project monitoring and management. At Rumah Sakit Pusat Otak Nasional Prof. Dr. dr. Mahar Mardiono Jakarta, which is where the research was conducted, the project management information system uses Ms Teams. In addition. With the use of previous PMIS, deficiencies can still be found, such as network connection problems, limited features, and data quality so that in this casefurther research is needed to obtain a more effective system. However, if there are limitations in the delivery of information, obstacles in supervision can occur. This study was conducted with those aim, and also to find out information on the construction process, to analysed the efficiency of the project monitoring relationship with website-based PMIS, and to see the effectiveness of website-based PMIS for the Rumah Sakit Pusat Otak Nasional Prof. Dr. dr. Mahar Mardiono Jakarta. The study was then conducted by collecting data on needs from at least 12 respondents through interviews, questionnaires, to parties who are considered to have a significant influence on the success of this project, such as project managers and informatics engineering experts. The research results show a tendency that website-based PMIS can fulfil and answer information needs in construction projects and increase time efficiency, especially in document distribution. In addition, the completion of features needs to be further considered and developed, specifically related to village display, data visualization, notifications, and accessibility
