Kekuatan coupler terhadap beban eksepsional dan ketahanannya terhadap beban kerja normal menjadi parameter keamanan yang sangat penting dalam operasinya. Kajian ini melakukan analisis deformasi secara numerik terhadap coupling element dari automatic mechanical coupler yang digunakan pada tipe kereta ringan (Light Rail Transit, LRT) berdasarkan beban aktual yang diterima. Bagian coupling element yang diteliti adalah coupling link dan hooked plate. Model solid 3D dibuat tanpa penyederhanaan untuk hasil simulasi yang lebih mendekati fenomena aktual. Material isotropik yang digunakan adalah baja ASTM A633 Grade E. Simulasi statis dan transien dilakukan untuk mendapatkan faktor keamanan statik dan dinamik. Simulasi fatik dari analisis pembebanan transien dengan tiga mode pembebanan dilaksanakan untuk memperkirakan umur kerja coupling element. Hasil simulasi menunjukkan bahwa coupling element yang diobservasi aman terhadap beban eksepsional dan normal yang diberikan. Selain itu, simulasi mengindikasikan bahwa komponen yang kritis berdasarkan tegangan von Mises maksimum adalah coupling link dan komponen yang kritis berdasarkan siklus umur adalah hooked plate.","PeriodicalId":233858,"journal":{"name":"Jurnal Teknik Mesin Indonesia","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125164075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Penderita tuna daksa menempati posisi kedua setelah gangguan pada penglihatan. Amputasi bawah lutut adalah salah satu bentuk tuna daksa yang banyak terjadi di Indonesia. Pasien amputasi bawah lutut akan kesulitan berjalan karena ketiadaan organ akibat amputasi. Prostesis bawah lutut merupakan alat pengganti organ bawah lutut. Prostesis bawah lutut akan membantu penderita amputasi bawah lutut agar dapat berdiri dan berjalan. Saat ini, produk prostesis bawah lutut yang ada di Indonesia masih memiliki banyak kekurangan. Pembuatan prostesis masih menggunakan metode custom sehingga membutuhkan proses pembuatan yang lama dan harga yang relatif mahal. Produksi massal tentu dapat menjadi solusi untuk menekan harga dan waktu pembuatan. Desain prostesis bawah lutut yang dapat mengakomodasi rentang antropometri orang Indonesia diperlukan agar prostesis bawah lutut dapat diproduksi secara massal. Hasil pembuatan desain kemudian diuji melalui simulasi sesuai standar ISO 10328 sebelum pembuatan prototipe dan produksi. Prostesis bawah lutut tersebut dirancang untuk mampu menahan beban 100 kg dengan safety factor 4. Selain itu, prostesis bawah lutut yang telah dirancang dapat digunakan untuk penderita yang memiliki rentang tinggi badan antara 150 cm hingga 180 cm.","PeriodicalId":233858,"journal":{"name":"Jurnal Teknik Mesin Indonesia","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116376547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Impeder yang digunakan dalam mesin las perlu didinginkan untuk menjaga suhunya di bawah 35oC. Cairan pendingin adalah air dengan 2% cutting oil dan disebut pendingin. Itu harus memasukkan impeder pada 15oC. Laju aliran yang dibutuhkan adalah sebanyak 30 lt / mnt. Untuk memastikan suhu impeder dijaga lebih rendah dari suhu yang dibutuhkan, maka penukar panas harus dirancang untuk mendinginkan pendingin dari 40oC hingga 15oC. Air chiller berpendingin udara tipe UWAP750AY3 digunakan untuk menghasilkan air dingin yang dibutuhkan oleh penukar panas. Pipa tembaga bersirip 5/8-inci digunakan sebagai tabung di penukar panas. Pendingin dibagi dalam empat tabung yang sama dari header. Untuk memenuhi area perpindahan panas yang dibutuhkan, setiap tabung akan ditekuk untuk membuat 10 lintasan (atau baris). Di akhir baris terakhir, empat aliran akan dikumpulkan di header. Kemudian, pendingin akan diedarkan ke impeder dengan suhu yang dibutuhkan. Simulasi numerik dilakukan untuk mendapatkan vektor kecepatan dan distribusi suhu aliran di dalam tabung, dan juga penurunan tekanan aliran melintasi tabung dan header. Vektor kecepatan aliran di sekitar tikungan balik, aliran masuk dan keluar menarik. Mereka memberikan pemahaman bahwa penurunan tekanan akan lebih tinggi pada aksesori semacam itu daripada pada pipa lurus. Penurunan tekanan cairan pendingin yang mengalir di dalam tabung penukar panas adalah 5143,2 Pa dari solusi analitis dan 4611,4 Pa dari simulasi numerik menggunakan Fluent. Temperatur cairan pendingin di outlet yang didapat dari simulasi numerik hampir sama dengan suhu yang dirancang, yaitu 15oC. Jadi, simulasi numerik memperkuat desain penukar panas.","PeriodicalId":233858,"journal":{"name":"Jurnal Teknik Mesin Indonesia","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115332501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dependence on fossil fuels can be seen from Indonesia’s energy usage. Nowadays, energy consumption is dominated by petroleum (46.9%), natural gas (21.9%), coal (26.4%), and other (4.8%). Therefore, to reduce dependence on fossil fuels, biomass can be used as alternative energy which is renewable. In addition, technology required to improve the combustion efficiency is necessary. To convert solid fuel into gas fuel is gasification process. In this research, the downdraft gasification type reactor was tested. In this test, results obtained are CGE (Cold Gas Efficiency) by 41.1% and the gas content of CO2 (2.98%), H2 (2.66%), N2 (66.99%), CO (15.71 %), CH4 (2.98%), H2S (0.15%) with an AFR of 2.47","PeriodicalId":233858,"journal":{"name":"Jurnal Teknik Mesin Indonesia","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127322234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
