Abstract

Plastic waste is a type of inorganic waste that takes around 50-80 million years to decompose in the soil. Plastic waste contributes to 90% of the waste in the ocean, causing damage to coastal ecosystems and having implications for the degradation of coastal ecosystems. To overcome this, the Mayor of Bontang has prepared a legal product that regulates the use of plastic waste and one of the efforts the author has made to tackle plastic waste in Bontang City is to create a tool that can convert plastic waste into fuel oil. The aim of this research is to determine the process of utilizing plastic waste into fuel oil and to determine the volume of fuel oil produced from processing plastic waste. This research is experimental research using the pyrolysis method. The trial results of processing plastic waste into fuel oil show that: the technology that is practically used is using the slow pyrolysis method with simple tools, the use of plastic waste into fuel oil is very effective to implement. Meanwhile, the volume of fuel oil for 1.4 kg is 350 ml at a temperature of 225℃ with a residence time of 4 hours. However, if the temperature is increased to 400-600℃, it is likely that the oil produced will increase.

Abstract

Industri adalah salah satu sektor yang telah menggunakan robot dalam pekerjaannya untuk memenuhi kebutuhan konsumen secara efisien, terutama dalam tugas pick and place yang memerlukan tingkat keamanan, kecepatan, presisi, dan konsistensi yang tinggi. Untuk mencapai tujuan tersebut, telah dikembangkan sebuah robot delta yang cocok untuk menjalankan tugas ini, terutama dalam industri pengemasan. Penelitian ini bertujuan untuk merancang bangun robot delta yang menggunakan Arduino Uno sebagai kontroler. Penelitian ini juga membahas tentang desain mekanik robot delta, pemrograman Arduino Uno untuk mengontrol robot, serta hasil uji coba dan evaluasi performa robot dalam menjalankan tugas. Hasil akhir dari penelitian ini adalah robot delta yang dapat mengambil dan meletakan objek benda yang berupa objek kotak secara manual dengan menentukan sudut-sudut motor Servo yang telah ditentukan. Lengan atas memiliki panjang antara poros ke poros sejauh 8,3 cm dan panjang dari ujung ke ujung 10 cm. Lengan bawah memiliki panjang antara poros ke poros sepanjang 21,7 cm. Penggunaan gripper pada end effector mampu menangkap benda dengan lebar maksimum 4 cm. Untuk ketinggian sumbu Z, robot memiliki rentang jangkauan dari 170 mm hingga 305 mm, dan tingkat keberhasilan rata-rata pada setiap perpindahan posisi yang dilakukan robot delta adalah 97.87%, untuk keberhasilan sumbu X = 98.82%, sumbu Y = 97.28%, sumbu +X+Y -X-Y = 99.17%, dan sumbu -X+Y +X-Y = 96.22%, serta robot delta memiliki error akurasi rata-rata sebesar 2.19 mm, dengan error akurasi paling besar mencapai 4.24 mm ketika kembali ke posisi awal.

Abstract

Abstract: Padukuhan Karangrejek, Karangtengah, Imogiri, Bantul, is a sloping area prone to landslides due to high rainfall, soil erosion, and vegetation degradation. Landslides often threaten the safety of residents, damage infrastructure, and disrupt the sustainability of the local environment and economy. This study aims to apply bioengineering through the planting of slope-stabilizing plants to improve slope resistance to landslides using an environmentally friendly and sustainable nature-based approach. The methods included surveying planting locations, preparing planting holes, making tree marker boards, and participatory phased planting with the community. The types of plants used were Munggur, Soursop, Jackfruit, and Teak, which have strong root systems to strengthen soil structure and reduce erosion. The results showed an increase in soil cohesion through root penetration, a reduction in rainwater runoff, suppression of erosion, and a decrease in the risk of subsequent landslides. The positive impacts included increased soil water retention, improved soil fertility, community empowerment in disaster management, and economic added value from fruit and timber crops. Conclusion The application of bioengineering with Munggur, Soursop, Jackfruit, and Teak trees is an effective, inexpensive, and sustainable solution for landslide mitigation in Karangrejek Hamlet. Recommendations include monitoring growth periodically, expanding planting to other slopes, and integrating the program into the village's disaster resilience plan for long-term sustainability.
