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

Pemberdayaan Kemitraan Masyarakat (PKM) bagi Kelompok Usaha Bersama (KUB) Congkel Jaya Desa Maja, Kalianda Lampung Selatan telah dilakukan melalui penerapan karya dosen berupa teknologi tepat guna mesin terintegrasi perebus (sistem multi-layer)-pengering (sistem hybrid). Tujuannya untuk mengatasi permasalahan mitra dalam proses pengolahan ikan asin, yaitu proses perebusan ikan yang tidak efisien dan ekonomis, serta proses pengeringan ikan yang tidak higenis dan lama. Dengan penerapan teknologi ini, mitra dapat menghasilkan produk ikan asin dan olahan ikan lainnya yang higienis dan berkualitas, sehingga dapat meningkatkan pendapatan mitra. Tulisan ini membahas tentang pengujian unjuk kerja mesin terintegrasi itu untuk mengeringkan ikan teri asin. Pengujian ini menggunakan tiga sumber panas, yaitu sinar matahari, sinar matahari berbantuan pemanas bola lampu, serta berbantuan pemanas keramik infrared. Ikan teri asin hasil pengeringan juga diuji mutunya dengan metode Proksimat lengkap (uji laboratorium). Hasil pengujian menunjukkan bahwa pengeringan ikan teri dengan sumber panas sinar matahari berbantuan pemanas keramik infrared menghasilkan waktu tercepat untuk mencapai nilai kadar air yang sesuai standar SNI (≤40%) dan kebiasaan mitra, yaitu sekitar 2 jam. Waktu pengeringan itu jauh lebih cepat jika dibandingkan dengan waktu pengeringan ikan teri dengan proses pengeringan tradisional, yaitu sekitar 4 jam. Dari pengujian laboratorium, ikan teri asin hasil pengeringan dapat diketahui mutunya, yaitu nilai kadar air sebesar 29,93% (memenuhi mutu standar SNI, ≤40%), (2) nilai kadar lemak adalah 51,31%, (3) nilai kadar protein adalah adalah 14,46%, (4) nilai kadar abu atau mineral adalah 3,19%, dan (5) nilai kadar karbohidrat adalah 0,39%. Bagaimanapun, pengujian lebih lanjut menyangkut keamanan pangan (food security) perlu dilakukan, seperti pengujian bahan berbahaya (formalin/boraks) dan toksisitas. Kegiatan pemberdayaan masyarakat ini juga dapat berkontribusi pada peningkatan kinerja Universitas Lampung, khususnya Indikator Kinerja Utama (IKU), melalui penerapan karya dosen di masyarakat dan pengalaman pembelajaran di luar kampus bagi mahasiswa.

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

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

The process of cutting low carbon steel (ST-37) typically utilizes High-Speed Steel (HSS) tools owing to their high hardness, affordability, and ease of shaping tool geometry. In machining, tool geometry plays a crucial role in the material cutting process and determines the quality of the final product, particularly surface roughness. The objective of this research is to achieve optimal surface roughness by varying the tool geometry and nose radius. This study employed an experimental approach using ST-37 and HSS tools. The variations in tool geometry include side rake angles of 12°, 15°, and 18°; side cutting edge angles of 85°, 80°, and 75°; and nose radii of 0 mm, 0.4 mm, and 0.8 mm. The machining parameters applied consist of a cutting depth of 1 mm and 2 mm, spindle rotation speeds of 185 rpm, 425 rpm, and 624 rpm, and a feed rate of 0.05 mm/rev, 0.075 mm/rev, and 0.1 mm/rev. Tool wear measurements were captured using a USB camera, whereas the surface roughness was assessed using a surface roughness tester. The impact of the tool geometry on the surface roughness was analyzed using the Taguchi-Grey Relational Analysis (Taguchi-GRA) and ANOVA methods. The optimal combination for ST-37 lathe machining with a sharpening tool is: A1 (cutting depth 1 mm), B1 (cutting speed 17.42 m/min), C3 (feed 0.05 mm/rev), D1 (corner radius 0 mm), E3 (side rake angle γ 18°), and F3 (side cutting edge angle γ 75°). According to the Analysis of Variance (ANOVA), three factors—cutting speed, tool tip angle, and chip angle—should be considered to achieve minimal tool wear and desirable surface roughness during machining
