Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh variasi parameter mesin CNC laser cutting terhadap kualitas hasil pemotongan plat baja SPHC. Parameter yang divariasikan meliputi kecepatan potong, fokus laser, tekanan gas oksigen, dan jenis nozzle. Dua spesimen diuji dengan pengaturan parameter yang berbeda. Spesimen 1, dengan kecepatan potong 2,3 m/min, fokus laser 5 mm, tekanan gas oksigen 0,5 BAR, dan nozzle berdiameter 1,5 mm, menghasilkan potongan halus, presisi, dan minim terak. Sebaliknya, Spesimen 2, dengan kecepatan potong 1 m/min, fokus laser 3 mm, dan nozzle 2,0 mm, menghasilkan potongan kasar dengan akumulasi terak. Hasil penelitian menunjukkan bahwa variasi parameter secara signifikan mempengaruhi kualitas potongan, di mana kombinasi parameter yang tepat mampu menghasilkan permukaan potong yang bersih, presisi tinggi, dan minim cacat. Temuan ini menegaskan pentingnya optimalisasi parameter mesin CNC laser cutting untuk efisiensi proses dan hasil produksi sesuai spesifikasi. Kata kunci: CNC Laser Cutting, Variasi Parameter Pemotongan, Plat Baja SPHC, Kecepatan Potong, Fokus Laser, Tekanan Gas Oksigen, Nozzle, Kualitas Permukaan.

Abstract

Processing of agricultural products, especially coffee, has an important role in the economy of rural communities. One of the main stages in coffee processing is the drying process, which aims to reduce the water content to an optimal level in order to maintain the quality of the coffee beans. In Mekar Buana Village, Tegalwaru District, Karawang, the drying process is still done manually, so it takes a long time and produces non-uniform quality. To overcome this problem, this research designed an automatic coffee drying machine based on Arduino Uno with the support of Internet of Things (IoT) technology. This machine allows automatic temperature and humidity settings and can be monitored remotely. Design analysis and static load stress testing were carried out using SolidWorks software to ensure the resistance of the machine structure to operational loads. The research results show that the designed machine is able to work optimally, increase the efficiency of drying time, and maintain the quality of coffee beans better than traditional methods. It is hoped that the implementation of this machine can increase the productivity of coffee farmers and support technological innovation in the agricultural sector.

Abstract

The Furnace Chikka machine at PT. Xx plays a crucial role in the company’s production and operations. As one of the main tools used in material processing, this machine must function optimally to maintain production flow. However, over time, various potential failures can occur in the furnace system, which can affect its performance and efficiency. Therefore, an analysis is conducted to identify the risks that may arise and propose appropriate solutions. The method used in this study is Failure Mode and Effect Analysis (FMEA), aimed at identifying potential failure modes in the furnace machine, assessing their impact, and calculating the level of risk that could arise. Data collection is carried out through field observations, discussions with technicians, and literature review. The risk assessment utilizes three main parameters: Severity, Occurrence, and Detection, which are calculated to determine the Risk Priority Number (RPN). The results of this study provide recommendations for maintenance and early detection to minimize further damage.

Abstract

Kabupaten Indramayu secara geografis terletak antara garis bujur 107° 52’ – 108° 36’ BT dan garis lintang 6° 15’ – 6° 40’ LS. Secara geografis berada di ketinggian 0 – 25 meter dpl dan berbatas langsung dengan laut Jawa, maka ancaman bencana yang sering terjadi seperti banjir, kekeringan, air pasang (rob), abrasi/ erosi pantai dan bencana lainnya. Dengan kondisi banjir besar perlu upaya mempercepat untuk dilakukan berbagai langkah Penanggulangan antara lain pertolongan, penyelamatan, pemberian bantuan logstik, hunian sementara, pemenuhan kebutuhan dasar, pelayanan kesehatan dan kebutuhan air bersih. Adanya berbagai tuntutan tersebut maka muncul yang disebut kebutuhan logistik untuk korban bencana. Dinas Badan Penanggulangan Bencana Daerah (BPBD) bertanggung jawab memberikan bantuan logistik. Pemberian bantuan logistik oleh petugas berdasarkan kondisi bencana dan kriteria-kriteria korban bencana banjir yang telah ditentukan, karena sangat diperlukan untuk menentukan daerah mana yang akan terlebih dahulu diberikan bantuan logistik sesuai dengan kebutuhan. Metode Weighted Product (WP), diharapkan bisa lebih tepat dan akurat dalam menyelesaikan masalah tersebut,sehingga sesuai dengan maksud dan tujuan yaitu berdasarkan data dan kriteria yang sudah ditentukan, maka dapat menentukan prioritas pemberian bantuan logistik bencana banjir.
