Abstract

Porous concrete is concrete that has cavities in its structure so that water can drain. The aim of this research is to obtain compressive strength and porosity referring to the Aci 522R-10 method using a cylindrical mold measuring 15 cm x 30 cm with a soaking age of 28 days. The highest compressive strength values ​​were obtained in porous concrete specimens mixed with 10% brown shell with an average compressive strength value of 11.7 Mpa and porous concrete mixed with 5% zeolite with an average compressive strength of 11,6 Mpa. The lowest compressive strength of porous concrete mixed with 5% zeolite + 10% brown skin with an average compressive strength of 5.5 Mpa and concrete mixed with 10% zeolite + 5% brown skin with an average compressive strength of 5,9 Mpa. The highest porosity was obtained in the 10% zeolite mixture variation test object and the 5% zeolite mixture + 5% brown leather variation test object, namely 27,6%.

Abstract

The development of digital technology in the Industrial Revolution 4.0 era requires vocational high school students to have strong technological literacy (Budiman & Ramdhani, 2022). However, limited hardware is a barrier, especially in the practice of Arduino microcontrollers (Lestari & Putra, 2020). This study aims to improve students' technological literacy through seminars and simulation training using Proteus software. A qualitative descriptive method was applied to 40 students majoring in Computer Engineering (TKJ) and Electronics at SMK Negeri 1 Tanjung Tiram. Activities included a basic Arduino seminar, simulation training on an Arduino Uno project using the HC-SR04 ultrasonic sensor, and evaluation through observation, tests, and questionnaires. The results showed that students were able to understand input-output, write simple code, and design virtual circuits (Santoso et al., 2023). They also experienced improvements in analysis, problem-solving, and learning motivation. The majority of participants considered the simulation easier to understand and encouraged interest in innovation (Karim & Yuliana, 2023). Thus, the use of Proteus effectively improves students' understanding and skills, while also being a solution to the limited practical facilities in vocational schools (Yusuf & Anwar, 2024).
