"Dua buah komponen penyusun sistem sendi lutut buatan yaitu Gliding dan Femoral support terbuat dari material polymer (polyethelene) dan salah satu metoda proses pengolahan material ini adalah dengan menggunakan metoda injeksi cetakan (injeksi molding). Dengan digunakannnya metoda ini diharapkan produk memenuhi standar dengan proses pengerjaan akhir seminimal mungkin.
Sehubungan dengan hal tersebut diharapkan dengan penelitian ini dapat memberikan suatu rancangan proses manufaktur dengan metoda injeksi cetakan, dan dapat digunakan sebagai masukan untuk mempertimbangkan pemilihan metoda ini dalam manufakturnya serta hasil rancangan prosesnya dapat digunakan sebagai bahan acuan untuk proses produksi selanjutnya.
Dalam metoda injeksi cetakan sangat dipengaruhi oleh faktor :cetakan, pemilihan proses, material dan mesin injeksi. Dalam penelitian ini spesifikasi material yang digunakan adalah Polyethelene yang memiliki jangkauan penyusutan sebesar 1.2 - 2.2 % dan kapasitas mesin injeksi yang digunakan sebesar 80 ton.
Tahap awal pengerjaan adalah penentuan rancangan cetakan yang menggunakan model cetakan dua bagian serta jenis Family mold serta faktor penyusutan sebesar 2%. Perhitungan parameter proses injeksi dilakukan dengan dua metoda yaitu perhitungan eksak serta simulasi komputer menggunakan program Quick Fi - Mold. Parameter proses ini yang digunakan dalam implementasi ke produksi.
Dari hasil implementasi proses diperoleh :
Rancangan proses manufaktur secara manual atau simulasi dapat ditetapkan pada kondisi produksi, dan dapat digunakan sebagai acuan.
Produk akhir tetap memerlukan pengecekan akhir walaupun proses pengerjaan akhir telah minimal. Biaya produksi sebesar Rp 500.

Gliding and femoral support, the two components of knee joint prostheses are mode from polymer resin (polyethelene) and one of manufacturing method to process this resin is by injection molding. By this method we hope there is minimal finishing process.
In connection with it, hoping that this thesis could give an injection molding manufacturing process design especially for joint prostheses.
Injection Molding process is very influenced by mold, process choosing, raw material and machine. In this thesis resin material which is used is polyethelene with 2% shrinkage factor.
The first step in designing is mold design and injection process parameter which is calculated by exact method and compare by computer simulation method.
From process implementation it was found that :
- Exact and simulation calculating method could be implemented in actual production process.
Although products has minimal finishing process, it still need inspections process. Production cost is about Rp 500 per set."

"Kemampuan dalam menghadirkan sebuah produk yang dapat dipastikan tingkat reliability, availabilty, dan mantainability sudah menjadi syarat tersendiri bagi para industri di tengah masyarakat ini. Di dalam siklus hidup sebuah produk, ada tiga tahap utama yang menentukan sifat pokok produk tersebut yakni, tahap perencanaan, produksi, dan penggunaan-pemeliharaan. Penelitian yang ada telah menghadirkan pemodelan perhitungan kompleksitas sistem manufaktur sebagai salah satu jenis alat ukur sebuah produk ketika melewati tahap produksi. Penelitian ini mengadaptasi pemodelan perhitungan kompleksitas ke dalam lingkungan lain yakni pada tahap pemeliharaan dengan menguraikan karakterisasi semua parameter yang berpengaruh dalam setiap tahapan pemeliharaan ke dalam model perhitungan kompleksitas. Pembobotan multi tier ranking dan normalisasi sebagai bagian dalam model perhitungan digunakan untuk menilai parameter parameter tersebut kedalam bentuk angka kuantitatif Pemodelan ini akan berperan sebagai tool untuk menilai kegiatan pemeliharaan yang dijalani oleh sebuah produk Perancangan pemodelan perhitungan kompleksitas pemeliharaan ini ditempuh melalui implementasi pada studi kasus pemeliharaan sepeda motor 100cc dan 883cc. Hasil yang diperoleh adalah nilai indeks kompleksitas pemeliharaan sebesar 79 65 untuk sepeda motor 100cc dan 88 67 untuk sepeda motor 883cc. Pembentukan model perhitungan indeks kompleksitas akan dibahas lebih detail di dalam penelitian ini.

The ability to deliver a product, that has the right levels of reliability, availabilty, and mantainability, has become a mandatory requirement for any industry in this era of society. In a product lifecycle, there are three main stages that determine those basic properties in a product, they are : stage of development, production, and use - maintenance. Existing research has presented the complexity of the manufacturing system modeling calculations as a tool to asses a product as it passes through the production stage. This thesis adapted the computation modeling complexity into another environment : the stage of maintenance, by outlining all the parameters, that influence every activity in the maintenance system, into the the model calculations of complexity. Multi-tier ranking and normalization, as part of the calculation model, are being used to assess these parameters in the form of numbers (quantitative). For this time being, this model will serve as a tool to assess the maintenance activities undertaken by a product. The modeling design of maintenance complexity is achieved through the implementation of maintenance case study from 100cc and 883cc motorcycles. The results of the maintenance complexity from the study case are respectively 79.65 for motorcycles 100cc, and 88.67 for 883cc motorcycles. The development for the modeling design of maintenance complexity will be discussed further in this thesis."

"Finding the novelty in and developing new science and engineering applications in the world is very important and interesting. Overall, process and product engineering aims to improve and increase the effectiveness of the engineering process in order to achieve the optimum conditions. However, engineering and environmental applications still contain various limitations such as high energy demand, catalyst costs, and less reuse or regeneration of adsorbents and catalysts. These challenges have led to the exploration of cheaper precursors, the regeneration of adsorbents or catalysts, mechanisms reactions, and overall optimization of the engineering process. Moreover, multifunctional and advanced materials could be promising as materials for further applications. To the best of our knowledge, investigation and exploration of the precursors, methods, design, instruments, product, and/or manufacturing is required for the future as they facilitate and integrate with each other. The adsorption process is a simple and important method for many applications within the environment and industries to deal with the removal of heavy metals, pollutants, and odor from wastewater, and to tackle polluted air. Clean energy sources and global warming have been major issues and challenges for many years, including a reduction of co2. Much attention has been paid to the key issue of developing alternative uses for by-products (waste) in addressing the sustainability of this resource. In particular, the utilization of any by-product (waste) as a useful product should be considered as a source of economic, eco-friendly, high-efficiency, and renewable materials, and should follow at least one rule, such as the “polluter pays” principle. This is expected to pave the way for the attainment of advanced applications. All of the findings of this research are effective and may be used to enable the further development of environmental applications for the removal of a diverse range of pollutants, diminish hazardous pollutants, and facilitate the minimization method for the management of waste. On the other hand, to improve the production of renewable energy and further applications, the overall process also needs to be considered, including the temperature, time, feedstock composition, catalyst, and arrangement of the design.to address the above problems, the 2nd international tropical renewable energy conference (i-trec) 2017 was held on october 3–4, 2017 at the courtyard by marriott bali nusa dua resort, bali, indonesia. The 2nd i-trec 2017 was proudly organized by the tropical renewable energy center, faculty of engineering, universitas indonesia. The main theme of the 2nd i-trec 2017 was “towards tropical renewable energy innovation and technology integration.” The 168 presented papers came from various countries, such as australia, brunei darussalam, brazil, france, indonesia, japan, and malaysia. The 2nd i-trec 2017 covered three symposia, namely renewable energy system and regulation, biomass and biotechnology, and multifunctional and advanced materials for renewable energy applications. From a total of 168 papers from the three symposia, we selected 22 for publication in ijtech. The papers are from a range of fields, as follows: architecture (1), chemical engineering (9), civil engineering (1), electrical engineering (1), mechanical engineering (7), and metallurgical and materials engineering (3). All of the 22 selected papers from the three symposia are summarized below."
