Abstract

The background of the palette bolster printer machine production is the availability of waste sawdust in the large number. Waste sawdust is often regarded as a waste that its values and benefits cannot be felt yet. Sawdust can be used as the primary material for the production of palette bolster, so it becomes  valuable and useful. The method used in the machine production are reviewing literature and by doing calculations. The next stage is the production of machines and testing process to find out the success of the design. After the production process, it is obtained the machine results with dimensions of 380×150×510 (mm), with the production capacity of 2 products in one-time process. A good mixture composition of the sawdust and adhesive is 60:40 with a production capacity of 12 per hour, the machine is expected to provide benefits in the palette production. Key words: Adhesive, bolster, pallet, sawdust.

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

Abstract This study aims to create a versatile multipurpose machine design to support increasing production of Usaha Masyarakat Kecil Menengah (UMKM), especially in the business of onion slices that are ready to be fried. The design of this machine has several concepts with steps such as: requirement, problem analysis and specification, design of machine concept, technical analysis, modeling up to work drawing, tool making, assembling and testing. This machine uses electric motors with low power and the price is relatively cheap, so this machine is affordable for the community of UMKM. After doing research on slicing machine of onion by using onion slicer got maximum capacity of 55 kg per hour with 400 rpm slicing knife rotation and 1 mm slice thickness. Keywords: Designing, Chopping Machine, Red Onion, Slicer

Abstract

The strength of international competitiveness encourages companies to do optimization. Therefore, the increase in productivity which improves competitiveness must be done. The purpose of this study is to look for the best solution to optimize designs with the best value and cheapest engineering approach that can be executed on the sink faucet production. After a value engineering, obtained high-cost items such as components with brass/metal, local and imported material. Then look for alternative designs with cost criteria, namely Life Circle Cost (LCC) and the Initial Cost as well as with zero one non-cost criteria matrix and pairs matrix. The result obtained a design that qualifies for the product by replacing the faucet's construction and dimensions but still meets the requirements of comfort, functionality, and safety in use. With this alternative earned savings of 19.6% of the total cost.

Abstract

This study evaluates the effectiveness of a laser marking machine in an instant noodle packaging line using a Total Productive Maintenance (TPM) framework and Overall Equipment Effectiveness (OEE) metrics over a 12‑month period. A mixed‑method design combined direct observation, semi‑structured interviews with operators and technicians, and a literature review to assess availability, performance efficiency, and quality rate. The machine achieved excellent availability, averaging 98.95%, reflecting the impact of preventive maintenance in reducing unplanned downtime. Performance efficiency varied substantially, ranging from 59.13% to 93.27%, indicating significant headroom for productivity improvement through cycle‑time stabilization and minor‑stoppage reduction. The quality rate averaged 89.21% and remained relatively stable, though still short of ideal benchmarks, suggesting the need for tighter in‑process quality control. The monthly OEE peaked at 84.77% in April, approaching the JIPM benchmark of 85%, while the period average was 60.38%, underscoring the need for sustained improvement initiatives. Among the three components, performance efficiency exerted the greatest influence on OEE due to its high variability across months.

Abstract

The development of autonomous vehicles is crucial for enhancing driving safety, comfort, and efficiency. This research presents the design of a self-driving Remote Controlled (RC) car at a 1:10 scale, equipped with a lane-keeping system and a pure pursuit controller. The primary objective is to evaluate the effectiveness of integrating computer vision techniques with trajectory tracking control to maintain lane stability. Lane detection was achieved using a sliding windows algorithm, while polynomial fitting estimated the lane centerline. A stereo camera provided spatial perception, capturing images that were processed to determine the steering angle needed to minimize deviation between the lookahead point and the viewpoint of the vehicle. Experimental results show that the system-maintained lane position with minimal deviation, achieving an average steering angle of 90.44° on straight paths, 65.4° on right turns, and 113.1° on left turns. These results demonstrate the feasibility of combining vision-based lane detection with a pure pursuit controller to improve path-tracking accuracy and stability in autonomous vehicles.
