Abstract

PT. Gajah Tunggal Tbk adalah sebuah perusahaan yang bergerak dibidang manufaktur dengan produk ban untuk berbagai kendaraan dan kegunaan. Dalam proses produksi terhadap produk yang dihasilkan, masih terdapat produk cacat (khususnya cacat scrap blown) yang terjadi setiap hari dan bersifat fluktuatif, sehingga menyebabkan pengiriman produk kepada konsumen menjadi terlambat. Pada penelitian ini, penulis ingin mengatasi masalah tersebut dengan metode yang cocok untuk mengurangi cacat dan mengendalikan mutu produk adalah dengan menggunakan metode QCC (Quality Control Circle) dengan menerapkan langkah PDCA (Plan-Do-Check-Action) dan dengan alat bantu Seven Tools (Stratifikasi, Grafik Histogram, Diagram Pareto, Diagram Sebab-Akibat, Grafik Pengendali). Setelah dilakukan perbaikan dengan metode tersebut, hasilnya terbukti menurunkan rata-rata persentase cacat scrap blown dari 0.54% menjadi 0.16% dan menurunkan rata-rata persentase total cacat scrap dari 3.29% menjadi 1.70%. Untuk megurangi cacat scrap blown dibuatlah SOP baru sebagai acuan saat proses produksi dan tindakan lainnya untuk mengurangi cacat scrap produksi guna mencapai target scrap 1%. Jadi, faktor yang menyebabkan cacat scrap blown adalah material kurang atau tidak lengket dan hasil implementasi dengan metode QCC dibantu dengan alat bantu seven tools dapat mengurangi atau menurunkan cacat scrap blown dan persentase total cacat scrap.

Abstract

As a source of energy in industry and power plants, turbines must have reliability in operation.. One that affects the performance of the turnin is the condition of the blades. The multi-cycle fatigue experienced by the blades of compressors and turbines caused by dynamic stresses caused by the vibration and resonance of the blades in the engine operating time is a common type of failure. Over the past five decades, researchers have studied and investigated turbine blade failure. The main purpose of this article is to provide a brief overview of recent studies on turbine blade failure. The author only focuses on describing some of the failure methodologies used in various studies to investigate turbine blades. This article discusses each of these factors in more detail

Abstract

Onions are the main ingredients for all types of cuisine so the level of demand is quite high. In the industrial world, a great number of processes of onion epidermis peeling are still using either manual and simple low capacity methods or high capacity machines with expensive components. Therefore, it is necessary to make a high capacity machine to peel the onion epidermis in a short time by using inexpensive and durable components that are designed with the help of Solidworks software. The onion epidermis peeling and smoothing machine uses a  0.5 HP electric motor power as a bond drive and  a rubber friction method for the process of peeling the onion epidermis. Besides, this machine is also designed to be compatible with peeling by connecting the rotation of the motor that is directly connected to the electric motor so that its design is simpler and does not require a long cycle of time. This peeling process is able to peel 2 kg of onion in 3 minutes and 0.5 kg for the refinement process in 5 minutes.

Abstract

One of the important components in the process of spot welding or spot welding is electrode tip or better known as”eltip". The quality of eltip material will greatly determine the welding results, the level of reliability and service life of eltip. The purpose of this study was to analyze the characteristics of eltip and find a suitable formulation of locally produced eltip to replace imported eltip. The chemical composition of the eltip material that is currently used is unknown and is a secret for import manufacturers. Local production Eltip used spot welding process has a disadvantage in service life. For this reason, chemical composition tests, hardness tests, and metallographic tests were carried out on the tip electrode. In the results of spot welding metallographic test and tark test, the results showed a minimum nugget diameter of 3 mm for 1 mm thick welding plate, can be met between 3.22 mm to 3.52 mm by local eltip. The service life of local eltip as many as 2000 spots is approaching the service life of imported eltip as many as 2400 spots. A slight improvement in Pb levels as an anti-wear will increase the service life of this local eltip in subsequent use. With reference to the quality standards of the Weld, such as the dimensions of the nugget, and visual check welding surface defects allowed by the car manufacturer, the results of this study are expected to be a reference for the use of eltip in the welding process elsewhere.
