Abstract

Museum Penerangan is one of tourist attractions which is visited by tourist to increase the knowledge of lighting development in Indonesia. Museum Penerangan has fire protection system, but the reliability of building safety system of potential fire hazard needs to be known. This research is conducted to acknowledge Museum Penerangan reliability of building safety system. Reliability variables used in this research are the completeness of treads, safety tools, active fire protective systems, and passive fire protective systems. The research obtains the value of reliability of Museum Penerangan building safety system for potential fire hazard is 68,9895, which means Moderate. This value is inadequate to minimum requirements of reliability of building safety system that has value of 80 or Good. This is due to safety tools component’s variable that has value of 58,57. It is recommended for the Museum Penerangan management to increase or develop the safety tools’ components that have been lacking of function so that the building could have a better reliability level of potential fire hazard.

Jenis penelitian yang dilakukan adalah deskriptif analitik. Metode yang digunakan pada penelitian ini adalah metode Taguchi untuk mengoptimasi radiasi medan elektromagnetik pada TV 32 inchi yang paling minimum dengan parameter (faktor) kontrol jarak (10, 20, dan 30 cm), Jenis Pencahayaan (Tabung, LCD, dan LED), dan Merk TV (Polytron, LG, dan Sharp) serta menggunakan Analisis Varians (ANOVA) untuk memperoleh secara kuantitatif memperkirakan kontribusi dari setiap faktor yang mempengaruhi besar Radiasi Medan Elektromagnetik. Dari hasil penelitian diperoleh besar Hasil Radiasi Medan Elektromagnetik yang minimum yaitu 32,5 Hz pada jarak (J) 30 cm, tipe pencahayaan adalah LED, merk TV adalah Sharp. Nilai ini masih di Ambang Batas Celling sesuai Peraturan Menteri Kesehatan Republik Indonesia No. 70 Tahun 2016. Nilai parameter yang berkonstribusi terbesar pengaruhnya terhadap Radiasi Medan Elektromagnetik adalah faktor Jarak ke TV yaitu sebesar 78,44%.

Abstract

Persaingan tenaga kerja terampil di Indonesia saat ini dipengaruhi oleh kebijakan nasional dan internasional. Masyarakat Ekonomi ASEAN dan Program Mewujudkan Masyarakat Indonesia yang Mandiri, Maju, Adil dan Makmur merupakan peluang sekaligus ancaman bagi tenaga kerja Indonesia dalam bersaing untuk memperoleh lapangan perkerjaan di Negaranya sendiri. Indonesia merupakan koordinator untuk sektor barang otomotif  dengan fokus kepada program pengembangan kendaraan angkutan umum murah pedesaan berbasis komponen lokal. Pengelasan memegang peranan penting dalam industri otomotif seperti dalam penyambungan plat untuk body kendaraan dan penyambungan rangka untuk chassis kendaraan. Teknologi bantu digunakan untuk mnejaga konsistensi kesejajaran antara pergerakan tangan juru las pemegang obor dengan sumbu alur pengelasan. Tulisan ini akan membahas tentang analisis kinematika dengan menggunakan metode perhitungan matematika serta simulasi metode elemen hingga. Berdasarkan hasil kedua metode tersebut desain dapat dinyatakan aman dengan nilai von misses stress antara 23.63 MPa hingga 27.57 MPa dan nilai tersebut masih jauh dibawah nilai yield strength material Mild Steel sebesar 207 MPa.

Abstract

Penelitian ini membahas analisis perbandingan kualitas produk kampas rem jenis cakram (disc brake) antara original dengan aftermarket . Analisis dilakukan pada hasil uji tribologi (uji friksi dan keausan), uji kekerasan, komposisi kimia dan struktur mikro untuk mengetahui ketahanan gesekan dan aus serta bahan yang digunakan. Dari hasil uji diperoleh perbandingan kualitas kampas rem original dan aftermarket yang lebih baik adalah original dimana nilai koefisienfriksi 0,14 dibanding 0,11, sedangkan keausan (kondisi normal) 1.35 x 10-7 g/mm2.detik dan 1.22 x 10-6 g/mm2.detik. Dari uji kekerasan diperoleh kampas rem original kekerasan rata-rata 65.567 HVN dan untuk aftermarket adalah 13.983 HVN, untuk hasil uji komposisi kimia dan struktur mikro menunjukan bahwa material kampas rem original menggunakan serat penguat berbahan karbon (C), tembaga (Cu), Besi (Fe) dan Alumunium (Al). Sedangkan bahan serat penguat yangterdapat pada kampas rem aftermarket adalah asbes, karbon (C), alumunium (Al) dan besi (Fe).

Abstract

Electrical Discharge Machining (EDM) merupakan pemesinan nonkonvensional yang memanfaatkan proses konversi listrik dan panas, dimana energi listrik digunakan untuk memunculkan loncatan bunga api dan proses pelepassan bahan terjadi akibat energi panas yang ditimbulkan dari bunga api tersebut.Keausan elektroda pada proses EDM die sinking merupakan peristiwa yang tidak dapat di hindari, namun dengan mengatur parameter pemotongan yang sesuai, diharapkan keausan yang terjadi pada elektroda se-minim mungkin dan pemakanan benda kerja semaksimal mungkin sehingga didapati tingkat akurasi ukuran pada benda kerja. Pada penelitian ini menggunakan metode Taguchi dengan L8 orthogonal array memakai elektroda bahan tembaga dan benda kerja material SKS 3. S/N ratio dan ANOVA menentukan performa parameter proses EDM dengan respon yang di teliti adalah Material Removal Rate (MRR) dan Tool Wear Rate (TWR). Hasil dari eksperimen tersebut menghasilkan parameter optimum Aruslevel 2= 6 A; Ponlevel 1=100 µs dan Pofflevel 1=50µs.

Abstract

The purpose of this research is to improve the performance of the disc friction welding machine that has been built and is operated, but there is a drawback, namely that there is no measuring device for process parameters such as rotational speed and forging load. In addition, during operation there is a vibration of 1.5 mm / s to 4.9 mm / s which is unacceptable according to ISO-2372 standards, so that these deficiencies can affect the quality of weld production. Repair or modification of this the friction welding machine is carried out by selecting and installing a rotating speed sensor (RPM) and load cell forging loads and installing rubber to dampen vibrations. Furthermore, the function test was carried out with the load, it was obtained that the rotational speed read on the LCD was 3.7% greater than the tachometer and the vibration decreased up to a value of 0.9 mm/s where this value was acceptable according to ISO-2372, while the performance test resulted in welding production for 3 workpieces with plate sheet material AA-110, ASTM A36 and CU-DHP copper with the same thickness, namely 1mm. From the results of the specimen tensile test of the three materials, it was found that the breakdown location was in the welding area where the tensile test value was around 1.2 to 5.1% of the tensile value of the workpiece material.
