Abstract

The electronics manufacturing industry, particularly in Printed Circuit Board (PCB) assembly for LCD televisions, requires highly efficient production systems to meet output targets and improve labor productivity. One of the critical issues frequently encountered is assembly line imbalance, characterized by bottlenecks, idle time, and uneven workload distribution across workstations. This study aims to optimize line balancing in the PCB production line of LCD TV Model P14xx by integrating the Ranked Positional Weight (RPW) method with a Lean Manufacturing approach. The research begins with an initial condition analysis to evaluate line efficiency, balance delay, and bottleneck locations. Subsequently, Lean Manufacturing tools are applied to identify and eliminate non-value-added activities (waste) within the production process. The RPW method is then implemented to optimize task allocation based on positional weights while considering precedence constraints. The results demonstrate that the integrated approach significantly improves production system performance. Line efficiency increases from 69% to 82%, while balance delay decreases from 31% to 18%. Additionally, the number of workstations is reduced from 15 to 10, and labor productivity improves from 10.5 to 15.4 units per operator.

Abstract

The rapid growth of vertical housing in urban areas increases the complexity of plumbing system management, as the system must ensure reliable water supply, energy efficiency, and service performance for a large number of occupants simultaneously. However, most plumbing system designs still rely on conventional assumptions such as 120 L/person/day water demand and 3 days of storage capacity, which often do not represent the actual consumption patterns of modern buildings. This study aims to evaluate the efficiency and capacity suitability of plumbing systems in high-rise residential buildings based on occupant water demand and supporting facilities. The novelty of this research lies in the development of an integrated Key Performance Indicators (KPI) framework consisting of four main dimensions: water efficiency, pump energy efficiency, hydraulic service quality, and user comfort. The research method involves numerical analysis of water demand based on the number of occupants, evaluation of Ground Water Tank (GWT) and Sewage Treatment Plant (STP) capacities, and system performance assessment using quantitative KPI metrics. The results demonstrate that the proposed evaluation model effectively identifies operational efficiency levels and provides an analytical basis for optimizing plumbing capacity and sustainable building utility management.

Abstract

Penelitian ini menganalisis kinerja metode charging-discharging berbasis Arduino Nano untuk pengukuran resistansi sensor elastis (stretchable sensor) berbahan silikon yang dilapisi grease konduktif, dengan dukungan Universal Tensile Machine (UTM) rancang bangun mandiri sebagai perangkat pengujian elektromekanikal berbiaya rendah. Kebutuhan terhadap instrumen pengujian yang terjangkau dan mudah dimodifikasi menjadi latar belakang penelitian ini, mengingat alat elektromekanikal komersial umumnya memiliki biaya investasi yang sangat tinggi sehingga membatasi aksesibilitas bagi peneliti dengan sumber daya terbatas. Spesimen sensor elastis difabrikasi dari lembaran silikon laboratorium berukuran panjang 80 mm, lebar 10 mm, dan ketebalan 0,58 mm. Pengujian dilakukan selama 30 siklus tarik-lepas pada kecepatan konstan 200 mm/menit. Modul pengukur resistansi dirancang berdasarkan prinsip pembagi tegangan dengan rangkaian resistor bertingkat dari 100 Ω hingga 1 GΩ yang dikombinasikan dengan transistor PNP, sehingga mampu mengukur rentang resistansi yang sangat luas secara adaptif. Kinerja sistem divalidasi terhadap LCR-meter komersial (East Tester) dan menghasilkan koefisien korelasi R² = 0,9003, yang membuktikan bahwa metode charging-discharging berbasis Arduino mampu memberikan pengukuran resistansi yang akurat dan andal dalam skala laboratorium, sekaligus membuka potensi penerapannya pada pengembangan sensor elastis untuk aplikasi soft robotic dan sistem wearable.

Abstract

Lorry wheels at the boiling station of a Palm Oil Mill (PKS) are exposed to high-temperature saturated steam during the boiling process, which causes volume expansion and thermal stress in the wheel material. This study aims to analyze the effect of steam temperature on volume expansion and thermal stress on lorry wheels in the palm oil mill sterilization station. Data were obtained through direct observation and theoretical calculations using ASTM A36 steel material parameters. The results show that an increase in steam temperature from 110.27°C to 133.59°C causes volume expansion of up to 1.39 × 10⁻⁵ m³ and thermal stress of up to 241.41 MPa, approaching the material's yield strength (250 MPa). It is concluded that steam temperature significantly affects deformation and potential failure of lorry wheel material.

Abstract

Data loggers play a crucial role in real-time data acquisition and monitoring across various engineering applications, particularly in renewable energy systems such as photovoltaic (PV) panels. However, existing monitoring systems are often limited by relatively high implementation costs and low flexibility in system development and integration. Therefore, this study aims to develop an Arduino-based data logger that is cost-effective, flexible, and capable of real-time monitoring with high temporal resolution for PV systems. The method employed in this research is a design-and-build approach, which includes hardware design, software development, sensor calibration, and direct implementation on a photovoltaic panel system. The developed system is capable of acquiring data with a one-second sampling interval, enabling enhanced monitoring of the dynamic behavior of PV panels. The parameters measured include the output voltage of the panel and the back surface temperature of the photovoltaic panel. The recorded data are automatically stored on an SD card, supporting long-term data storage and further analysis using software such as Microsoft Excel. The experimental results indicate that the system operates reliably and stably under real operating conditions. The measured voltage ranges from 18 to 20 Volts, while the back surface temperature of the photovoltaic panel varies between 28°C and 51°C.

Abstract

 The current condition of the Matsumoto MDX-178F diesel engine for the Energy Efficient Car Competition (KMHE) is not at its maximum performance, the efficiency and torque it produces have decreased from the initial engine specifications. The purpose of this activity is to recondition and modify the air intake and exhaust system on the Matsumoto MDX-178F diesel engine to optimize engine performance, increase combustion efficiency, and reduce exhaust emissions. The reconditioning method begins with an evaluation of the air intake and exhaust system which includes components such as air ducts, filters, exhaust ducts, head parts, pistons, cylinders, injectors and other parts. Repairs or replacements are carried out on components that are damaged or require readjustment. The modification process is carried out by porting and polishing the intake and exhaust lines. The increase in air flow is measured using a flow bench, the increase in power is measured using a dynotest, the reduction in exhaust emissions is measured using an exhaust gas analyzer. This study provides a scientific contribution through the integrated application of reconditioning and geometric optimization of intake–exhaust channels based on porting and polishing in a single-cylinder diesel engine within the context of energy-efficient vehicles, an area that remains limited in previous research. The results of this reconditioning and modification can show a significant increase in engine performance, including increased power and combustion efficiency. so that the engine becomes more environmentally friendly. The conclusion shows that the reconditioning and modification of the intake and exhaust systems of the Matsumoto MDX-170F diesel engine not only improves engine performance, but also improves fuel economy and reduces environmental impact.

Sudut 45° menghasilkan kekasaran sedang dan sudut 55° menghasilkan kekasaran tertinggi. Perbedaan ini dipengaruhi oleh mekanisme pembentukan geram, gaya potong, dan kestabilan proses pemesinan. Dengan demikian sudut potong 60° merupakan sudut optimum untuk menghasilkan kualitas permukaan terbaik pada proses pembubutan material ST60. Kata Kunci - Pembubutan, Geometri Sudut Potong, Kekasaran Permukaan, Material ST60. AbstractTurning is one of the machining processes that plays an important role in the manufacturing industry to produce components with a high level of precision and good surface quality. The surface quality of the turning results is influenced by various factors, one of which is the geometry of the cutting angle of the tool. This study aims to analyze the effect of variations in the geometry of the cutting angle of 45°, 55°, and 60° on the surface roughness level of ST60 material. The method used is a quantitative experiment with a comparative approach where the turning process is carried out using a lathe and surface roughness testing is carried out using a surface roughness tester. The specimen is cylindrical with a length of 50 mm and a diameter of 25 mm. The results show that variations in the cutting angle have a significant effect on surface quality. The cutting angle of 60° produces the lowest roughness value with Ra of 2.464 µm, Rq of 3.073 µm, and Rz of 14.784 µm, thus producing the smoothest surface. The 45° angle produces medium roughness and the 55° angle produces the highest roughness. This difference is influenced by the chip formation mechanism, cutting forces, and machining stability. Therefore, a 60° cutting angle is the optimum angle for producing the best surface quality in the turning process of ST60 material.Send feedback. Keywords - Turning, Cutting Angle Geometry, Surface Roughness, ST60 Material.
