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.

Abstract

Permasalahan utama UKM kopi Lampung adalah rantai produksinya panjang, mesin atau peralatan pengolahannya masih konvensional dan tidak ramah lingkungan. Akibatnya, produk kopi yang dihasilkan berkualitas rendah, yaitu biji kopi memiliki kadar air hanya 18%, banyak pecah, tidak bersih dan tidak seragam. Juga energi fosil dan bahan bakar kayu dominan digunakan dalam lini produksi kopi sehingga tidak ramah lingkungan. Konsep produksi bersih dan sistem terpadu pengolahan kopi Lampung diterapkan, guna menjadikan industri kopi Lampung sebagai penghasil produk kopi berkualitas dan berdaya saing tinggi, serta ramah lingkungan. Penerapan konsep ini dibagi menjadi tiga tahap, yaitu pertama membuat model sistem produksi kopi. Tahap kedua menerapkan model ke dalam lini pengolahan kopi. Tahap terakhir mengevaluasi model yang telah diterapkan melalui penelitian untuk menyempurnakan model sistem produksi kopi. Sistem produksikopi Lampung telah diterapkan dan diperoleh hasil yaitu biji kopi dapat dikeringkan hingga kadar air 12,5% dengan waktu pengeringan sekitar 30 jam dan biji kopi yang dikupas tidak pecah. Biji kopi yang dihasilkan berukuran seragam dan bersih. Selain itu, limbah kopi dapat diubah menjadi energi panas melalui reaktor gasifikasi, yang suhunya sekitar 500°C dan alirannya terus menerus, sehingga dapat digunakan untuk mengeringkan dan memanggang biji kopi. Hasil yang diperoleh menunjukkan adanya peningkatan kualitas biji kopi sehingga UKM kopi diharapkan memiliki posisi tawar dan daya saing yang lebih baik dalam perdagangan kopi guna meningkatkan perekonomiannya. Selain itu, substitusi bahan bakar fosil dan kayu bakar menjadi energi panas yang berasal dari gasifikasi limbah kopi berpotensi menurunkan biaya produksi dan menciptakan kelestarian lingkungan.

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.
