Abstract

Wound should be covered with bandage that is called wound dressing. Most people use synthetic materials such as gauze dressing. Gauze has high absorption of NaCl, which is often used to cleanse the wound. However, discomfort and pain arise since the gauze becomes sticky on the wound. Therefore, we need other alternatives instead of gauze to cover wound. One such alternative is the alginate membrane. This study used alginate membrane with mixture of mucous of the snail Achatina fulica, which contain proteins such as proline, serine asparagine, glycosaminoglycan, hydroxylysine, trionin and so forth, to activate the growth factor. Alginatepowder and carboxymethl cellulose (CMC) was dissolved in distilled water mixed with mucus of the snail Achatina fulica in four variations (4:0; 4:1, 4:2, 4:3) through a magnetic stirrer, and casted on a baking sheet covered with sterile gauze. High Performance Liquid Chromatography (HPLC) test showed that the glycosaminoglycan content was found on the mucous of Achatina fulica. This was indicated by the appearance of peak at 325–350 second. The most optimum alginate and mucus composition was in ratio of 4:2. This ratio resulted in a wound dressing that was still able to absorb the exudate and optimally accelerated wound healing.

Abstract

Stent is one of the common solution that is offered to the patient with atherosclerosis. An ideal stent should have good mechanical and biological properties. This research aims to analyze how importance strut linker geometry affect mechanical behavior of stent especially on recoil percentage, foreshortening percentage and fatigue safety factor prediction using finite element analysis. The result showed that strut linker geometry would specify the mechanical behavior

Abstract

A patient-specific implant is a designed implant that considers the needs of a specialized patients condition. In several surgical cases, the implant design needs to be adjusted based on the patient bones surface to suit the bone morphometry. This study aims to conduct the finite element analysis to investigate the stress distribution alongside the plate to consider clinical implementation. A bone plate has been designed following an adult pelvic bone shape for the pelvic fractures clinical case management. An FEA was accomplished to analyse the implant designs performance and estimate the installations clinical failures before the manufacturing process. The FEA calculation achieved the highest number of von misses stresses (VM) on the pelvic bone plate by 3.616 MPa. The obtained VM number on the simulation is smaller than the yield strength of Ti6Al4V. It concludes that the customized iliac plates design using Ti6Al4V can have excellent mechanical strength and can withstand the loading. Additional similar simulation using another software strengthen the results.

Abstract

Total hip arthroplasty purposes to replace a hip joint damaged by an artificial hip joint. However, the developed products that already exist in the market lead to the mismatch between the hip implant equipment and the patient’s bone morphometric. Besides causing complications, the mismatch also continues to the dislocation effects, fracture, osteolysis, and thigh pain. This paper aims to design a customized hip implant based on real patient data, particularly for Indonesian patient, limited to the acetabular components and stem parts. The computed images were analyzed to estimate the patient proximal femur morphometric; those are the femoral head diameter, neck-shaft angle, mediolateral width, anteroposterior width, neck length and neck width. The experiment has succeeded in designing the acetabular shell with the thickness of 3 mm, the acetabular liner with the thickness of 6 mm, the femoral head between 22.4 to 24.8 mm, the short stem in both the right for 110.656 mm and left femur bone for 111.49 mm; that fit the patient's femur bone. Overall, the proposed steps in designing the customized hip implant in this work, based on image analysis on medical imaging data, can be a standard to be applied for other patient-needs hip arthroplasty implants.

Abstract

Preparat dahak sangat menular untuk dilakukan proses pengambilan hingga analisis. Uji preparat dahak selain digunakan untuk analisis bakteri TB (Tubercullosis) pada teknik BTA (Bakteri Tahan Asam), juga digunakan untuk sweb test covid 19. Pada teknik BTA, terjadi proses perhitungan bakteri dalam beberapa layang pandang pada preparat. Permasalahan yang terjadi adalah, proses perhitungan bakteri masih sebuah perkiraan. Padahal terdapat 4 klasifikasi dari preparat dahak, yaitu negatif, positif 1, positif 2 dan positif 3. Jika terjadi kesalahan diagnosis, maka akan terjadi kesalahan pengobatan yang berakibat pada resistansi bakteri sehingga TB makin sulit untuk disembuhkan. Melalui artikel ini, dibahas mengenali sebuah perancangan scanner 2D dari preparat dahak, yang digunakan untuk mengambil citra dahak setiap 1 layang pandang. Kendalanya adalah pada step langkah yang sangat pendek, yaitu 1 mm, maka motor harus disetting sedemikian rupa, agar mempunyai kesalahan perhitungan sekecil mungkin, karena terbedaan 1mm saja, artinya sudah kehilangan 1 layang pandang dari sample preparat dahak yang di scan. Produk tersebut kemudian diuji kinerjanya untuk melihat dari sisi stabilitas, keterkontrolan dan keteramatan. tidak stabil namun terkontrol dan teramati.

Abstract

A prosthetic leg is a lower extremity movement aid in assisting the mobility of persons with physical disabilities. A prosthetic leg is used to replace a missing leg, either due to a birth defect or an amputation. The use of a prosthetic leg is a different matter if the user has never experienced movement sensation. This service will evaluate the process of assisting the use of prosthetic legs for people with physical disabilities from birth. So far, prosthetic foot manufacturing services that have been carried out by the Prosthetic Orthosis Profession in Indonesia have focused on making sockets. Most users have physical abnormalities for a history of amputation or not birth defects. So that in the process of practicing the use of prosthetic legs there are no difficulties. It's different if the user of this prosthetic leg is congenital who has not felt the sensation of stepping movement at all or what is known as the gait cycle. Forms of community service activities in the process of assisting the use of prosthetic legs and evaluating any obstacles encountered in the walking process.

Abstract

Pola hidup yang tidak sehat sudah sangat melekat pada kehidupan manusia di zaman modern seperti saat ini. Merokok, makanan cepat saji dan berlemak tinggi, dan jarang berolahraga menjadi salah satu faktor yang dapat menyebabkan penyakit pada sistem kardiovaskular. Satu dari sepuluh kematian di dunia disebabkan oleh Penyakit pada sistem kardiovaskular. Peranan alat medis dalam mendeteksi detak jantung dan SpO2 untuk membantu dokter mendapatkan mendiagnosa gejala-gejala awal dari penyakit jantung. Seperti oximeter yang dapat mendeteksi detak jantung (heart rate) dan kadar oksigen dalam darah (SpO2), akan tetapi oximeter tidak dapat menampilkan diagnosis awal dari hasil yang telah didapatkan. Dimana pasien tetap dapat mengukur heart rate dan SpO2 sesaat setelah melakukan aktivitas sehari-hari lalu data yang nantinya didapat dan diolah akan dikirim ke web server yang sudah tersambung dengan dokter maupun perawat. Penelitian ini menggunakan sensor MAX30100 dimana sensor ini melakukan pengukuran dengan metode photoplethysmography yang nantinya akan mendapatkan nilai dari heart rate dan SpO2, lalu menggunakan NodeMCU ESP32 sebagai microcontroller yang berfungsi sebagai penyimpanan data dan alat bantu untuk mengirimkan data ke web server setelah dilakukannya proses clustering data agar dapat menampilkan indikasi dari hasil pengukuran dan menggunakan Organik LED (OLED) untuk menampilkan hasil pengukuran.
