Abstract

Peningkatan jumlah limbah konstruksi di Indonesia, yang disebabkan oleh intensnya Pembangunan infrastruktur nasional, menyebabkan masalah lingkungan yang serius karena masih banyak dilakukan pembuangan limbah secara terbuka. Praktik tersebut berdampak pada peningkatan emisi gas rumah kaca dan konsentrasi polutan udara di sekitar area pembuangan. Mengolah limbah konstruksi menjadi agregat melalui proses penghancuran merupakan salah satu caramendukung ekonomi sirkular di bidang konstruksi. Namun, mesin penghancur industry berukuran besar memiliki kapasitas dan biaya investasi tinggi, sehingga cukup sulit diakses untuk industry kecil maupun kegiatan penelitian. Penelitian ini bertujuan untuk merancang mesin penghancur berukuran menengah. Desain tersebut dilakukan dengan menerapkan metode sistematis VDI 2222. Hasil penelitian menunjukkan bahwa metode VDI 2222 mampu menghasilkan rancangan yang terstruktur dan sistematis, di mana setiap Keputusan dalam proses desain didasarkan pada dasar teknis yang jelas dan terperinci. Rancangan ini diharapkan bisa menjadi pilihan teknologi sederhana yang lebih murah bagi usaha kecil dan menengah daam mengolah limbah konstruksi, serta berfungsi sebagai acuan dalam pengembangan mesin penghancur skala menengah pada penelitian masa depan.

Abstract

This research aims to design a prototype of a landslide early warning device based on mechanical motion with an automatic displacement detector. The displacement of the soil pulls the rope and rotates the spool connected to the rotary encoder. The encoder pulse is processed by ESP32 into a linear displacement, displayed on a 16 × 2 I2C LCD, and used to activate the buzzer. The moisture sensor and MPU6050 function as supporting parameters. Seepage observations for 10 minutes produce a final value of 52 mm in loose soil, 28 mm in white or chalky soil, and 16 mm in clay. The system divides the prototype displacement range into Safe, Alert, Standby, and Caution from less than 1 mm to at least 9 mm. These thresholds have not yet become field hazard standards and still require calibration, documented repeated testing, and validation on actual slopes. The research methods include literature study, design, construction, programming, and testing on loose soil, clay, and white or chalky soil. The prototype uses a multi-level glass container measuring 85 cm × 35 cm × 60 cm with a media slope of 18.4°. The research results in a mechanical-electronic system designed to classify conditions based on shift values, ranging from safe, alert, standby, to caution. At the prototype scale, the warning range is set from shifts below 1 mm to at least 9 mm, with a continuously active buzzer at Warning III level. This threshold value is the prototype's operational threshold and still requires calibration and field testing before being used on actual slope conditions. This tool is expected to be an affordable alternative early warning system to help increase community awareness in landslide-prone areas.
