Abstract

Infrastructure development in Indonesia has undergone significant changes in construction materials, including concrete. This study aims to analyze the influence of sample shape and cement brand on the compressive strength of concrete. The analysis utilizes a factorial experimental design approach, with two factors: sample shape (cylinder and cube) and cement brand (Gresik, Tiga Roda, Holcim, and Merah Putih) as fixed factors. The total number of samples used is 30. Concrete compressive strength data were collected at the Muhammadiyah University Jember Laboratory, with samples immersed for 28 days. The data were analyzed using the two-way ANOVA method with SPSS software. The results of the analysis show no significant difference in the influence of sample shape on concrete compressive strength (Sig. 0.397 > 0.05). However, for the cement brand factor, there is a significant difference (Sig. 0.000 < 0.05). Statistically, there is no interaction between sample shape and cement brand on concrete compressive strength (Sig. 0.570 > 0.05). The practical application of this testing and methodology in the field of Civil Engineering, particularly in concrete technology, allows for the selection of the optimal sample shape between cubes and cylinders and the determination of high-quality cement brands for infrastructure projects.

Abstract

Saluran drainase merupakan salah satu fasilitas kota yang mutlak diperlukan agar tercapai suatu tatanan kota yang terpadu untuk mendapatkan suatu system drainase kota yang diharapkan. Pada perumahan Taman Anggrek terdapat pat penambahan cluster, akan tetapi drainase masih dalam tahap pengerjaan. Namun perlu diketahui lagi nilai debit limpasan dan limbah yang terjadi pada tiap saluran drainase. Dikarenakan untuk kedepannya pembangunan terus dilanjutkan dan juga bisa dikembangkan, sehingga akan memengaruhi infiltrasi dan koefisien aliran permukaan. Untuk mengetahui parameter yang cukup baik pada Perumahan Taman Anggrek dilakukan simulasi menggunakan Strom Water Management Model (SWMM) yang dikembangkan oleh Enviromental Protection Agency (EPA) dapat digunakan pemodelan hidrologi serta hidrolika air hujan, serta pengelolaan air limbah, untuk perhitungan menggunakan perbandingan manual excel dengan Software epa swmm 5.2. Melalui hasil perbandingan metode manual excel dengan Software EPA SWMM 5.2 terdapat perbedaan debit rencana manual excel pada saluran 1 sebesar 0,439, saluran 2 sebesar 0,306, saluran 3 sebesar 0,373, saluran 4 sebesar 0,270. Debit rencana Software EPA SWMM 5.2 pada saluran 1 sebesar 0,492, saluran 2 sebesar 0,406, saluran 3 sebesar 0,457, saluran 4 sebesar 0,336. Sehingga untuk penerapak di lapangan menggunakan debit yang paling besar. Kata Kunci: Drainase, Debit, Metode Rasional, EPA SWMM 5.2.

Abstract

Technological advances make it possible to utilize natural resources efficiently. However, shortages occur when demand exceeds supply, making goods/services an economic object. This service aims to increase students' understanding of these concepts and provide provisions for them to face economic challenges in the future. Implementation of the activity began with a survey to determine the purpose of the school where this service activity was to be held. From the results of the survey we decided to carry out the service at SMAN Tamanan, followed by coordination with the teaching staff and submitting a permission letter from the campus for the service activity. A survey was conducted to determine student understanding, then a pre-test was carried out to assess initial understanding. Next, the material is delivered with discussion, followed by questions and answers to discuss concepts and review understanding. After that, a post-test was carried out to measure students' understanding after education, and continued with descriptive statistical analysis of the collected data. The results of this activity show a significant increase in students' understanding after receiving a comprehensive explanation. The pre-test and post-test showed an increase in student understanding, with 26% of students showing an increase in understanding after the socialization activities. This shows that this activity is effective in increasing students' understanding of the basic concepts of engineering and investment economics. Overall, this report shows that the use of technical economics at SMAN 1 Tamanan has succeeded in raising vocational teaching standards, preparing students to face the demands of the business world, and improving the local economy. These findings highlight the importance of incorporating engineering economics into vocational education curricula as well as the need to continue to foster the professional growth of students and administrators.
