Abstract

Mesin 3D printer adalah mesin pembuat suatu model 3D. Metode mesin 3D printer yang digunakan pada Fakultas Teknologi Industri Universitas Trisakti adalah metode FDM (Fused Deposition Modelling). Diketahui adanya ketidak stabilan pada meja cetakan mesin 3D printer pada saat proses produksi dilakukan. Ketidak stabilan meja cetakan mesin 3D printer, menyebabkan tidak maksimalnya produk yang dihasilkan. Terdapat perbedaan antara hasil produk dengan bentuk produk yang telah di desain sebelumnya. Setelah diteliti lebih lanjut, ketidak rataan pada meja disebabkan pada pengaturan meja cetakan yang kurang sesuai. Hasil dari redesain dapat menstabilkan meja cetakan dan memudahkan untuk melakukan kalibrasi dan pengaturan pada meja cetakan mesin 3D printer. Hal ini terbukti ketelitian dimensi produk hasil cetakan yang meningkat dari penyimpangan terbesar 0,037 mm menjadi 0,069 mm, yang diukur dengan proyektor profil yang mempunyai kecermatan 1 mikrometer. 3D Printer Machine is a 3D shaped model making machine. The method of 3D printer machine used by the faculty OF Industrial Technology of Trisakti University is FDM (Fused Deposition Modelling) method. There is known unevenness on the build plate of 3D printer machines during the production process. The unevenness that appears on the objects makes the build plate used by the 3D printer engine unstable. This causes the product to be produced not maximal. There is a difference in shape between product results and previous product design. After further investigation, the unevenness of the table was caused by the improper arrangement of the printed table. The results of the redesign will stabilize the print table and make it easier to calibrate and adjust the print table of the 3D printer machine. This proven that precision of product dimension increase from 0,037 mm deviation to 0,004 mm, its measured with a profile projector has 1 micrometer resolution.

Abstract

Currently, the industrial era 4.0 coincides with the covid 19 virus which is an opportunity and a challenge to choose the right business strategy. Based on the results of the evaluation of previous studies and the analysis in this study, it is known that currently there are no sensors installed on the tools used for material transfer, communication between machines and machines (M2M) currently there is no data generated so no data is communicated, the interface between humans and machines (HMI) currently uses a local user interface through the Pro-St application and the interface on the fanuc machine, the current transportation system is moving materials to production machines, a manual transportation system, namely hand lifts, materials that have been packaged and will be stored in the warehouse using a forklift (machine for manual transportation), while the unit product movement from the fanuc machine already uses a conveyor, the transportation unit as an information carrier currently has a mechanism for individual identification of materials but the status of the material is not identified in the IT system, the current storage system for placing materials is still done intuitively and the identification process for storage locations is still listed manually on the blackboard. In order for the intralogistics system to implement intelligent supply chain and logistics based on industry 4.0, it is proposed to install sensors on the device to identify material movement and the sensor and actuator interaction data can be analyzed, network connections between devices for M2M communication, use of mobile user interfaces to monitor intralogistics processes and status. identified material in the IT system.

Abstract

Tren digitalisasi dalam industri manufaktur saat ini merupakan suatu kunci bagi terwujudnya proses manufaktur yang efektif dan efisien. Hal ini terutama menyangkut kualitas, waktu dan biaya produksi produk. Daya saing suatu produk akan meningkat jika ketiga hal tersebut dapat dioptimalkan. Permasalahannya adalah seringnya waktu yang terbuang karena harus melakukan proses perancangan dan perencanaan produk yang berulang pada produk–produk yang mempunyai kemiripan. Sistem kodifikasi merupakan konsep yang tepat untuk menyelesaikan permasalahan tersebut. Sebagai langkah awal, pendekatan GT (group technology) akan digunakan dalam membangun sistem kodifikasi untuk produk-produk flare tip yang merupakan salah satu  komponen penting dari flare stack. Hasil yang diharapkan dari perancangan sistem kodifikasi adalah waktu yang diperlukan untuk membuat desain produk dan perencanaan proses untuk produk–produk yang serupa dapat dipersingkat dan lebih sistematis dibandingkan menggunakan cara-cara konvensional.

Abstract

Flexibility in the design process becomes an absolute necessity in a smart factory in the era of industrial manufacturing 4.0. CAD technology with a 3D modeling capability serves as a backbone in the design process in a manufacturing industry. Here, iLogic serving as an add-on of Inventor software will be combined with a Decision Support System (DSS) to build a DSS application system, namely "Panel Auto System". This system will help an engineer modify a 3D model wall-mounting panel to fulfill a non-standard order from his or her customers. This 3D-model database from various parts of the wall-mounting panel is generated from the 3D modeling. Then, by employing the if/then/else rules in the iLogic, the system can modify a 3D model wall-mounting panel data standard and serves as a geometric 3D model based on the customer’s order. The system works well and has been validated. The efficiency of the modeling process using the "Panel Auto System" increases its time efficiency up to 97,6 % compared to a manual process. Therefore, this system can increase the engineer’s productivity in the design of an in-wall mounting panel, and the customers can get the order of their 3D model faster.

Abstract

3D Printing products are produced and used for many purposes like biomedical equipment, mechanical part, and so on. Therefore, mechanical properties are important for 3D Printing products.  Layer height as one of the 3D Printing process parameters will be observed to know the effect on product tensile strength and printing time. The research has used ASTM D638 standard specimens from PLA material base with layer height parameter variations between 0.1mm, and 0.3 mm. The specimens are printed by 3D Print Creality Ender 3-Pro, then will be tested by Tensile Machine. The result finds both the printing time and the tensile strength of 3D printing products are affected by the variations in the layer height. The printing time will decrease along with the layer height increasing. For the layer height dimension nearly the nozzle diameter of 0.3 mm, the tensile strength is 10.16 MPa. It is significantly better than the 0.1 mm to 0.25 mm layer height which has a tensile strength range of 7.07 to 8.59 MPa. The condition is because the path internal bond in the 0.3 mm layer height has more homogeneity.

Abstract

Additive Manufacturing (AM) adalah proses menambahkan material untuk membentuk suatu objek. Proses pembentukan tersebut dikenal sebagai 3D printing, yang memungkinkan untuk menciptakan suatu model atau prototipe yang lebih kompleks menjadi lebih mudah. Penelitian ini membahas mengenai pengaruh parameter kecepatan gerak nozel terhadap ketelitian dimensi dan kekasaran permukaan produk hasil cetak mesin 3D printer berbentuk kurva. Model didesain dalam bentuk kurva agar efek tangga (staircase effect) dapat terlihat dengan jelas, sehingga dapat dibandingkan perubahannya pada setiap kecepatan nozel yang berbeda. Benda yang sudah didesain pada perangkat lunak Catia kemudian diatur beberapa parameternya untuk pencetakan dengan perangkat lunak pengiris yaitu Ultimaker Cura (versi 4.8.0). Perbedaan parameter kecepatan dan penambahan support (pendukung) diatur pada perangkat lunak ini. Kemudian hasil kostumisasi tersebut akan disimpan dalam format GCode File. Parameter kecepatan yang diuji dalam penelitian ini 30mm/detik, 40 mm/detik, 50 mm/detik, 60 mm/detik, dan 70 mm/detik. Masing-masing GCode File dengan kecepatan yang berbeda akan dicetak sebanyak 5 kali. Setiap cetakan akan mempunyai hasil yang berbeda. Oleh karena itu, dilakukan pengukuran ketelitian dimensi dan kekasaran permukaan produk 3D printing agar didapatkan parameter kecepatan terbaik sebagai acuan referensi pencetakan prototipe suatu benda berbentuk kurva pada mesin 3D Printer FDM.

Abstract

The demand for local chicken meat supply in Lampung is relatively high, but it cannot be fully met now. Chicken farmers, who are the suppliers of local chicken meat, face difficulties due to the fluctuating supply of chicks for traditional chicken farming. The success rate of traditional chicken hatching is only around 50%, which necessitates the use of egg incubators to condition eggs in an ideal environment for hatching, thus minimizing hatching failures. The machine works by maintaining a consistent temperature in the incubation room throughout the hatching process, periodically rotating the eggs in four positions, and is equipped with temperature and humidity monitoring devices. In the Community Service Program (PkM), the approach used is a mentoring method, allowing farmers to ask questions directly if they encounter difficulties. The expected outcome is that chicken farmers will be able to assemble egg incubators independently, creating the egg-turning mechanism and the machine's casing, while other control and support tools will be purchased. During the mentoring process, farmers will be provided with working drawings for the driving mechanism, machine casing, and specifications of the necessary tools and materials. Farmers will also receive a step-by-step guide for assembly, making it easy to follow. At the end of the PkM, it is expected that farmers will have a minimum understanding of 90%-100 % of what was taught during the mentoring process, and for any remaining questions, they can consult online or through discussions on WhatsApp.
