Abstract

Indonesia berbatasan langsung dengan Negara Papua Nugini, Malaysia, Timor Leste, dan Brunei Darussalam yang menyebabkan patok batas negara rawan terkena sengketa wilayah, hilang maupun bergeser. Kasus pergeseran patok di perbatasan wilayah Indonesia terjadi dikarenakan akses ke perbatasan yang sulit dan memakan waktu lama. Isu ini yang mendasari peneliti dalam membuat projek penelitian yang dapat mencegah terjadinya pergeseran patok di wilayah perbatasan. Penelitian ini dibuat sebagai salah satu solusi dalam mengatasi pergeseran patok batas negara secara real-time dengan merancang dan membuat prototype smart patok batas negara yang terhubung langsung kepada petugas penjaga perbatasan kemudian akan dipantau oleh Poledrone ke titik koordinat patok seharusnya. Metode pembuatan alat yaitu perancangan sistem, pembuatan desain, pembuatan smart patok, pengujian fungsional alat dan evaluasi. Dengan menggabungkan teknologi GPS tracker, SMS gateaway, sensor piezoelectric, solar cell rechargeable battery sebagai opsional power supply dan Poledrone, menghasilkan suatu alat yang mampu mendeteksi apabila terjadi pergeseran pada patok batas negara. Fungsi utama smart patok selain dapat mendeteksi pergeseran dengan mengirim data titik koordinat melalui SMS juga dapat sebagai landing area Poledrone jika Poledrone tidak dapat memantau dari ketinggian di atas 1 Meter. Dengan demikian pemantauan patok batas negara menggunakan smart patok dan Poledrone dapat dilakukan dengan mudah, informasi cepat tersampaikan dan mengamankan wilayah di daerah perbatasan.

Abstract

Advances in additive manufacturing technology are driving the need for high-quality, affordable, and sustainable filaments. In Indonesia, the demand for filaments and extruders is largely met through imports, prompting researchers to innovate and develop filament extrusion machines, including those at the Politeknik Manufaktur Bandung, which has developed a filament extrusion machine equipped with a camera-based inspection and control system to produce high-quality filaments from LDPE gallon cap waste. This system integrates a digital microscope camera and a microcontroller to monitor the diameter of the extruded filament and correct the diameter by controlling the speed of the pull motor to stabilize the diameter in real-time. Image processing uses a color-based edge detection algorithm, and camera calibration results show a precision of 0,009 mm/pixel. Diameter data is sent to the Arduino Mega, which then uses the L298N driver to control motor speed via the Sliding Mode Control (SMC) method. Test results show that at 15 RPM, the average filament diameter is 1,77 mm with an error of 1,14%, while at 20 RPM it becomes 1,56 mm with a larger error of 10,86%, compared to the standard commercial filament size of 1,75mm. SMC control also demonstrated better performance than PID in terms of system accuracy in reaching the set point. This system could serve as an economic and ecological solution for local recycled filament production, reducing dependence on imported products.
