Abstract

Indonesia is the world's second-largest producer of natural rubber. Various products can be made of natural rubber. One of them is a foot prosthesis. An essential criterion for foot prosthesis is a significant value of friction force to prevent slip during usage. The present study optimizes natural rubber formulation to obtain the largest friction force value. A pin-on-disk tribometer is used to obtain friction force values. The optimization method used in the present study is Taguchi Method Orthogonal Array L9, while the contribution of each control factor to increase friction is carried out using ANOVA analysis. Four control factors are used in this study: the type of natural rubber, the percentage of silica powder, the percentage of sulfur, and the vulcanization temperature. Each control factor has three different levels. The test results showed that the optimum formulation to obtain the highest friction value is a mixture of concentrated natural rubber and instant natural rubber, 30 phr of silica powder, 5 phr of sulfur, and 150°C of vulcanization temperature. The friction force of the optimum formulation increases by 33% compared to the baseline formulation. ANOVA analysis shows that the vulcanization temperature is the most crucial factor in increasing the friction force, contributing 62.58%.

Abstract

Handphone Android memiliki berbagai sensor yang terintegrasi didalamnya. Hanya saja, sensor-sensor tersebut jarang dimanfaatkan di bidang robotika. Sensor pada Handphone Android yang dapat dimanfaatkan pada robot sepak bola adalah sensor visi berupa kamera dan sensor orientasi berupa kompas. Kamera Android dapat digunakan untuk mendeteksi objek berupa bola dan gawang, sedangkan sensor kompos dapat digunakan untuk mengetahui orientasi arah gawang musuh. Robot sepak bola yang telah dirancang dalam penelitian ini menunjukan kemampuan untuk menjalankan fungsinya dalam mencari dan mengejar bola, memposisikan diri ke arah gawang musuh dan kemudian membawa bola kearah gawang musuh. Handphone Android bisa menjadi alternatif pilihan dalam membangun robot sepak bola.

Abstract

The total number of health workers who died from COVID-19 infection reached two thousand people. The number of victims from medical personnel certainly needs to be a concern. Reducing the contact of medical workers with infected patients is an alternative solution to reduce the number of victims. Medical assistant robots are an alternative solution for helping medical workers to provide service to the infected patient. But, the most medical assistant robot did not have a mechanism to open the door. So, the robot becomes less effective if the health workers still have to open the door for the robot. Because of that, it is very crucial to develop a mechanism to open the door on a medical assistant robot. The research is focused on developing an opening door mechanism for the medical assistant robot that was made before. The results show that the opening door mechanism can help the medical assistant robot open the door. The test results also show that none of the door opening processes failed during ten times testing.
Rancang Bangun Alat Uji Dorsifleksi Telapak Kaki Prostesis Berdasarkan Standar ISO 10328 Khafidh, Muhammad; Pratama, Wahyudi; Nurudin, Tri; Suryawan, Donny; Kistriyani, Lilis; Aminah, Siti; Ismail, Rifky

Abstract

Kaki prostesis merupakan salah satu solusi bagi penderita amputasi kaki. Salah satu bagian kaki prostesis yang penting adalah telapak kaki prostesis yang biasanya terbuat dari elastomer. Saat ini produk telapak kaki prostesis di Indonesia masih didominasi oleh produk impor. Meskipun demikian, produk telapak kaki prostesis juga sudah diproduksi oleh UMKM lokal. Standar pengujian performa telapak kaki prostesis diatur dalam standar ISO 10328. Dalam standar ISO 10328, beberapa pengujian perlu dilakukan untuk mengetahui performa telapak kaki prostesis, salah satunya adalah uji dorsifleksi. Saat ini masih jarang ditemukan alat yang fokus pada pengujian performa produk telapak kaki prostesis. Penelitian ini fokus pada rancang bangun alat uji dorsifleksi untuk telapak kaki prostesis berdasarkan standar ISO 10328. Perancangan alat menggunakan metode morfologi untuk mendapatkan desain terbaik. Hasil perancangan menunjukkan bahwa alat uji dorsifleksi diproduksi dengan mengikuti prosedur ISO 10328 seperti lokasi pembebanan, besar beban, dan kecepatan penekanan. Telapak kaki produk lokal jenis Single Axis Cushion Heel (SACH) digunakan untuk mengetahui performa dari alat uji dorsifleksi yang diproduksi. Pengujian dilakukan dengan tiga kali pengulangan untuk memastikan keberulangan hasil. Sudut dorsifleksi dari spesimen telapak kaki lokal adalah 33,46 °.
