Abstract

Abstract:  This research was conducted to know the maneuver of public passenger car (PPC) on an intersection, to determine the passenger car equivalent (pce) of the public passenger car and to analyze whether the stopping near intersection, PPC reduces the actual saturation flow. From this research can be known that PPC prefer using left lane because the driver want to get the closest distance to the passenger waiting on the left side of the road. PPC also prefer stopping at the place where the passenger is comfortable for waiting near the intersection.The pce of PPC is different from the pce of light vehicle. Based on the capacity method, pce of PPC are 1.13 and 1.201. Based on the headway method, pce of PPC are 1.203 ans 1.234. The stopping PPCs near intersection reduce the saturation flow. The reduction of the saturation flow caused by the stopping PPC are 0.929 and 0.938.Key words: intersection, passenger car equivalent, public passenger carAbstrak:  Penelitian ini dilakukan untuk mengetahui perilaku mobil penumpang umum (MPU) pada suatu persimpangan jalan, menentukan nilai ekivalensi mobil penumpang (emp) dari mobil penumpang umum tersebut dan meneliti adakah pengaruh dari mobil penumpang umum yang berhenti di dekat persimpangan jalan terhadap arus jenuh yang terjadi. Dari penelitian ini dapat diketahui bahwa mobil penumpang umum sering menggunakan lajur sebelah kiri yang disebabkan karena adanya keinginan dari pengemudi mobil penumpang umum untuk mendapatkan jarak yang terdekat dengan calon penumpang yang menunggu di sebelah kiri jalan. Selain itu mobil penumpang umum cenderung untuk berhenti di tempat adanya calon penumpang, yaitu di dekat persimpangan jalan yang memiliki kondisi nyaman untuk menunggu. Nilai ekivalensi mobil penumpang umum berbeda dengan mobil pribadi atau kendaraan ringan lainnya. Hal ini dapat dilihat dari nilai emp dari mobil penumpang umum antara 1,13 sampai dengan 1,201 hasil dari metode kapasitas dan antara 1,203 sampai dengan 1,234 hasil dari metode headway. Kebiasaan berhenti mobil penumpang umum di dekat persimpangan ternyata mereduksi arus jenuh yang terjadi. Perbandingan arus jenuh yang terjadi pada kondisi adanya mobil penumpang umum yang berhenti dibandingkan dengan arus jenuh tanpa adanya mobil penumpang umum yang berhenti sebesar 0,929 sampai dengan 0,938.Kata kunci: persimpangan, ekivalensi mobil penumpang, mobil penumpang umum

Abstract

Abstract. Buildings with component degradation are a common challenge for all construction companies across the world. There are various building's components that it is challenging for construction companies to manage them all at once. It was not considered that the building agency is responsible for more than one building at a time. These issues have gotten more complicated as a result of the building agencies' limited financial resources for building maintenance. This study attempts to provide a visible solution to manage the building maintenance strategy based on complex building maintenance problems. The Analytical Hierarchy Process was used to give a complete way for assessing the building's condition (AHP). This method developed in this study was applied to define the building condition and followed by determining the building priority to be maintained. The building component in this study was specified into three specific components such as interior, exterior, and building utility. To complete this method, a three-level priority factor was determined with consideration from the safety factor follow by the functionality factor, dan the last is an esthetic factor. The developed model shows a proper and reliable solution related to the degradation of building components and their functionalities.

Abstract

Repetitive construction requires continuous and uninterrupted supply of resources; hence, a suitable scheduling method that matches the work characteristics is required. Line of Balance is a scheduling method in the form of a line chart that represents recurring work. Considering the existing work items, Ngasem Overpass Bridge Solo-Yogyakarta-NYIA Kulon Progo Toll Road Project can be categorized as a repetitive construction project. Therefore, this research tries to apply LoB to this overpass project to determine whether LoB can efficiently manage a repetitive construction project. Two scheduling scenarios are applied in this study. The first scenario is implemented with the aim of producing a schedule that uses resources continuously and uninterruptedly. While the second scenario is applied to produce a schedule with the shortest duration. LoB based on the first scenario succeeded in compiling a schedule that uses resources continuously and uninterruptedly. Schedule based on the second scenario results in the shortest duration by severing the use of resources for short-duration jobs that are preceded and followed by longer-duration jobs. In addition to generating schedules according to the desired scenario, LoB has proved its ease in managing scheduling in terms of the continuity of resource use and the speed of completion of work.

Abstract

Effective water quality management is crucial for fish hatcheries to ensure survival and productivity. At the Fish Hatchery Center (BBI) Cangkiran Mijen, water quality monitoring is still conducted manually, leading to unstable pond conditions. To improve monitoring efficiency, SMARCOS (Smart Water Conditioning System) was developed as a Web-IoT-based system for automated monitoring of water parameters such as pH, oxygen, and temperature. The program involved pond data collection, expert consultation, system design, testing, implementation, and partner training. Evaluation was conducted through satisfaction surveys and system performance monitoring. Results showed that SMARCOS effectively corrected water quality parameters automatically, enhanced monitoring efficiency, and provided easy access to information via an IoT-based website. Surveys indicated that partners were satisfied with the system’s usability. The adoption of IoT for water quality monitoring significantly improved the efficiency and accuracy of hatchery pond management. Training sessions also increased partner understanding of IoT technology. The success of SMARCOS demonstrates that IoT can be an innovative solution for fisheries modernization, with potential replication in other hatcheries to enhance productivity and efficiency in aquaculture.

Abstract

Economic and technological advances in Indonesia require vocational school graduates to be able to work competently according to their fields. The Ministry of Education and Culture supports the 21st century learning model which refers to the 4C skills, namely Communication, Collaboration, Critical Thinking and Creative. Achievement in the learning process is used to measure the achievement of goals and the intelligence of students. To be able to enter and survive in the world of work, it is also necessary to prepare attitudes, character and skills in work or employability skills that start from the learning process. This study aims to analyze the influence of 4C skills in improving employability skills and learning outcomes. The approach used in this study is quantitative with the student population of the DPIB Expertise Program of SMK Negeri 3 Semarang. The sampling technique uses a total sampling of 72 respondents. This study uses multiple linear regression analysis techniques that have previously gone through analytical tests including (1) Normality Test, (2) Homogeneity Test, (3) Linearity Test. The results of the study showed that (1) there was an influence between learning achievement on 4C skills with a T value of 4.660, (2) there was an influence between employability skills on 4C skills with a T value of 9.520, and (3) there was a simultaneous effect between learning achievement and employability skills against 4C skills with an F value of 55.937. The simultaneous correlation of the three variables was 78.6% with a simultaneous influence value of 61.9%, the remaining value of 38.1% was influenced by other factors that were not studied by the researcher.

Abstract

Syntactic foam is a lightweight, high‑strength composite consisting of a polymer matrix filled with hollow microspheres (microballoons). This study examines how the volume fraction of glass‑clad silica microballoons K15 (10–50 vol %) affects the density, porosity, and void distribution of epoxy‑bonded syntactic foams. Specimens were molded in accordance with ASTM D790, conditioned for 48 h (23 ± 2 °C; 50  ±  5 % RH), and their density was measured by the pycnometric method specified in ASTM D792. Porosity was calculated theoretically and validated by SEM–EDS imaging of fracture cross‑sections. Results show a linear decrease in density from 1.15 g cm⁻³ (0 vol %) to 0.63 g cm⁻³ (50 vol %), while porosity rises exponentially from 2.7 % to 18.4 %. Morphological analysis confirms a homogeneous microballoon dispersion up to 30 vol %, but agglomeration and interbinder voids appear above 40 vol %, leading to uncontrolled porosity. A strong negative correlation (R² = 0.96) is observed between density and effective porosity. A 30 vol % K15 loading is identified as the optimum, achieving a 28 % density reduction without a significant porosity spike. These findings provide a basis for designing sandwich cores and amphibious flotation structures that require high strength‑to‑weight ratios.
