Abstract

Dalam pembedahan ortopedi, mata bor berfungsi sebagai alat bantu membuat lubang untuk sekrup dalam upaya perbaikan fraktur atau pemasangan perangkat prostetik. Selama proses pengeboran berlangsung akan meyebabkan peningkatan suhu pada area pengeboran, kenaikan suhu melampaui batas yang diijinkan akan mengakibatkan matinya sel-sel tulang akibat kehilangan suplai darah yang disebut dengan nekrosis. Untuk mencegah peningkatan suhu berlebihan tersebut, salah satu cara yang dapat dilakukan adalah dengan melakukan pemilihan geometri mata bor menggunakan finite-element analysis model tiga dimensi untuk mendapatkan nilai temperatur pengeboran tulang yang serendah mungkin. Penelitian ini berfokus pada nilai point angle 118°, yang dikombinasikan dengan nilai helix angle 13°, 20°, 28° dan 30°. Dari kombinasi tersebut menghasilkan nilai temperatur optimal pada helix angle 28° dengan suhu maksimum pada 38.814° C.

Abstract

Osteochondritis dissecans, sebuah kondisi yang sering terjadi pada atlet, menyebabkan perubahan tulang subkondral fokal yang mengakibatkan fragmentasi osteokondral. Total Knee Replacement (TKR) adalah solusi untuk mengatasi kerusakan sendi lutut, tetapi tantangan muncul dalam memilih implan tulang komersial yang mungkin tidak sesuai dengan struktur anatomi pasien, terutama pada pasien Indonesia. Ketidaksesuaian ini dapat menyebabkan reaksi nyeri pascaoperasi. Untuk mengatasi hal ini, peneliti mengusulkan sebuah studi menggunakan rekayasa balik dengan CT scanning untuk merekonstruksi tulang lutut pasien menjadi model TKR 3D. Metode non-invasif ini bertujuan untuk merancang implan TKR yang sejajar dengan struktur tulang lutut pasien, khususnya yang disesuaikan untuk pasien Indonesia. Proses ini melibatkan CT scanning, analisis ahli, perbaikan citra, dan menggunakan metode Boundary Surface untuk membuat model implan TKR. Validasi dilakukan dengan membandingkan gambar digital 3D tulang lutut pasien dengan model implan, menghasilkan implan tulang lutut TKR 3D yang disesuaikan sesuai dengan anatomi pasien.

Abstract

As a person ages, usually after age 50, knee joint bone damage caused by osteoarthritis can occur. It is to cause pain in the knee joint so that its function moves abnormally. The knee joint bone damage could be replaced with a prosthesis (Total Knee Replacement, TKR) to restore the knee joint's normal movement function. However, orthopaedic doctors sometimes have difficulty choosing standard implant designs available for patients' knees when performing TKR surgery, especially for Asian patients, including Indonesians. It is due to the geometry of the standard implant being different from the patient's knee anatomical shape. As a result, postoperative pain reactions can occur. Therefore, this study is to customize the TKR femoral implant's design according to the knee bone's geometry, especially in Indonesian patients. Reverse Engineering (RE) technology assisted by the CT-Scan and the boundary surface technique was applied for reconstructing the patient's knee bone into a femoral implant. The application of RE is initially, the patient's knee bone sample was scanned with Computer Tomography (CT) Scan. Then, the femur implant model was designed on the surface of the patient's knee bone using the boundary surface method. The 3D model of the TKR femoral implant was successfully designed to match the geometry of the patient's femur bone. It will be a reference for designing other TKR implants, namely the tibia component.

Abstract

Bone drilling is processing to create holes in bone when joining fractured bone parts with bolts. The bone temperature can increase during the bone drilling, causing necrosis and reducing stability and fixation strength. The temperature of bone necrosis can be controlled by applying the appropriate bone drilling parameters. This study experimentally examines the effect of drilling parameters on the temperature during bone drilling using the full-factorial design method. The material test was bovine bone, which its mechanical properties similar to human bone. The bone temperature was measured using two temperature-measuring instruments: a thermocouple (K type) and a Thermal Camera. The study results show that the drill speed and diameter significantly impact the temperature of bone and bone chips. The Increasing in drill speed and diameter increased the bone temperature. The temperature of bone necrosis (>47oC) was found mainly in bone chips when the drill speed was 2800 rpm, and the drill diameters were 4 and 6 mm. The bone temperature prediction model was also made with a correlation value of about 80-90% and an absolute error rate of about 5-7%, so that can be declared accurate in predicting the bone temperature. This model will later help control the temperature of bone necrosis

Abstract

This research aims to obtain optimal drilling machining parameters in response to tool life, surface roughness and response to the influence of electric current. Tool life is a derivative of the wear value obtained. The Taguchi method is often used to determine optimal quality in single response manufacturing processes. However, when there is more than one response, researchers often use the Gray Relational Analysis (GRA) method. This research was carried out on the response of tool life, surface roughness and the effect of electric current on Magneisum AZ31B type material using four factors and mix levels. The chisel diameters used are 8 mm and 10 mm. The spindle speed is set at 890 rpm, 1270 rpm, 1700 rpm and 2000 rpm, feeding uses values of 0.1 mm and 0.3 mm, while the point angles used are 118° and 135°. The optimal results obtained in this research were using a tool diameter of 8 mm, spindle speed of 890 rpm, feeding of 0.1 mm, and point angle of 118°. Keywords: Drilling, Taguchi Method, Gray Relational Analysis, Tool Wear, Surface Roughness, Electric Current.

Abstract

Pada pendidikan tingkat sekolah menengah atas sudah dapat berpikir dengan pendidikan selanjutnya. Lulusan sekolah menengah atas hanya berbekal ilmu-ilmu teori yang didapat dari sekolah. Sehingga mereka sedikit sekali yang mempunyai skill, khususnya pada bidang teknologi. Sehingga siswa sekolah kususnya siswa SMA perlu dibekali teknologi terapan. Sebagai contoh pengalaman dalam bidang penyambungan menggunakan teknologi pengelasan. Dari bimbingan teknis pengelasan bagi siswa adalah memberi wawasan dan membekali ketrampilan lulusan. Sehingga diharapkan dengan adanya kegiatan ini bisa menambah skill siswa SMA untuk dapat bersinergi dengan melakukan ilmu terapan. Metode yang digunakan adalah persentasi, perancangan atau desain produk dan aplikasi pengelasan sehingga metode yang paling efektif adalah model praktek langsung hingga menghasilkan produk. Pemberian materi di kelas dilaksanakan 1 pertemuan dan praktek lapangan dilaksanakan 2 pertemuan. Dari pengamaatan selama dilakukan kegiatan ini sebagian besar siswa mengikuti kegiatan dengan sungguh-sungguh sehingga pada saat dilakukan praktek pengelasan ada beberapa siswa yang mampu melaksanakan pengelasan dengan baik. Sehingga dapat disimpulkan bahwa pengabdian ini dapat membangkitkan motivasi anak anak untuk mengembangkan pengelasan sebagai alternatif usaha lulusan.

Abstract

Applications for worm gear drives are common in industry. The crown worm drive is a new kind of inventive worm drive that has just been proposed. Nevertheless, no prior research has been done on the geometric design of crown worm gears with straight-lined blade profiles. On the other hand, designing the cutting tool depends on the geometric design of the workpiece surface modeling. As a result, this study proposed a geometric design for the straight-lined blade shape of the crown worm gear. Numerical examples are used to evaluate the accuracy and applicability of the suggested mathematical model. Furthermore, the modeling of a variable center-distance crown worm gear is completed. It is also feasible to model the crown worm gear using different tool profiles, such as concave and convex profiles.

Abstract

Cortical bone drilling is a critical step performed prior to implant bolt placement, where drilling parameters play a significant role in the success of the procedure. This study investigates the effects of rotational speed, feed rate, and cooling fluid type on the outcome of the drilling process. A Box-Behnken experimental design was employed, involving 15 samples. Drilling operations were conducted using an SS316L drill bit on a 3-axis CNC machine. Circularity was analyzed using a Mitutoyo PJ3000 profile projector by measuring the x- and y-axis lines of the drill hole shadows under projector illumination. Hardness testing of bone specimens revealed an average microhardness of 45.48 HV with a standard deviation of 1.74, indicating their suitability as a human bone model. The lowest circularity value, 0.00125, was achieved at a rotational speed of 1,500 rpm, a feed rate of 60 mm/min, and in the absence of coolant. ANOVA results show that the feed rate (Vf) significantly affects circularity compared to rotational speed (V) and coolant, with a P-value of 0.0126 and an F-value of 8.86. These findings provide insights for optimizing cortical bone drilling procedures in biomedical applications. Future research should explore temperature distribution across the specimen and drill bit wear resistance resulting from the drilling process.
