Dunia konstruksi masih banyak ditemukan proyek yang pelaksanaannya tidak sesuai waktu yang ditentukan. Oleh karena itu perlu dilakukan evaluasi penerapan manajemen waktu pada proyek konstruksi gedung Ciputra School of Business yang mengalami keterlambatan pada beberapa sub bagian pekerjaan. Metode penelitian yang digunakan dalam penelitian ini yaitu metode analisis deskriptif. Dari hasil penelitian dapat diketahui bahwa dalam pelaksanaan proyek kurva-S digunakan sebagai time schedule dalam melakukan monitoring progress dan penjadwalan pekerjaan, kontraktor perlu melakukan pekerjaan secara paralel dengan metode percepatan fast tracking dan memberlakukan lembur agar target mingguan dan bulanan terpenuhi. Dari hasil analisis dapat disimpulkan bahwa pengendalian menggunakan kurva-S dimana baseline dilakukan pertiga bulan selama 1 tahun waktu pelaksanaan menunjukkan besaran deviasi progress pekerjaan pada tahap pertama 1.085%, tahap kedua 1.324%, tahap ketiga -8,971%, dan tahap keempat -5,639%
Parties in the supply chain system that carry out the construction of roads and bridges in Eastern Indonesia from procurement to implementation mainly consist of the owners who represent the community in the upstream and the supervisory consultants, contractors, subcontractors, and suppliers in the downstream. The project proposed in this paper will be successful if the parties carry out the process in an integrated manner according to government regulations. There has been no research on the integration of the parties from the procurement to execution stages. The existing research generally still regards the execution stage. The research objective of this project is to analyze the integration of parties in the supply chain system for the successful execution of road and bridge projects in Eastern Indonesia. To determine whether the integrated practice between parties in the supply chain system can be attributed exclusively to the successful implementation of the project, a questionnaire format was developed. Data collection took place from September 2019 to March 2020. Thirty respondents represented Owners (X1), Contractors and Subcontractors (X2), Supervisory Consultants (X3), and Suppliers (X4), whereas the success of the project’s implementation was represented with (Y). Data were analyzed using multiple linear regression. The analysis result of R-squared = 0.96 means that the parties are significantly integrated. F = 147.92 means that the variant of the regression model is good. P-value or significance F < 0.05 means that the parties’ integration is very significant for the project’s success.
Undershot waterwheels have been used by the people in rural areas to lift and distribute the water to the bottom which is higher than the water source. Waterwheels has a relatively simple design, large diameter, high speed and high torque. But applying it as a microhydro with high speed and small diameter still has to be explored. Waterwheels can operate efficiently in locations with high flow speeds. The Waterwheel functions from a waterwheel blade as a place to ride water so that the wheel can spin. From the results of the study, it can be concluded that the higher the flow of water with a large number of buckets, the speed of rotation of the wheel will be slower. Conversely, the lower the flow of water with the number of buckets a little then the spinning wheel is faster.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
