Abstract

Solar energy is a renewable energy source that is abundantly availabe in Indonesia.  One way to untilize solar energy is to convert it into electrical energy using photovotaic modules or solar panel called solar power plants (PLTS).  The construction of solar power plants can accelerate the electrification ratio and reduce fossil materials.  In this research, it will make a 100 Wp solar cell will be used by using a 1000 watt inverter by testing the place at the Cilegon City from 08:00 – 17:00 WIB.   Making PLTS is done by identifying components – components such as:  solar panel, DC wattmeter, SCC ( Solar Charge Controller), batteries, 1 phase MCB, and AC wattmeter.  At this PLTS the maximum power produced is 47,87 watts at 13:00 WIB.  And the minimum power produced 31,90 watts at 17:00 WIB.  It can be concluded that this PLTS can be used to help remote areas that have not yet been energized.Keywords: Solar energy, Solar Cell 100 Wp

Abstract

Corporate Governance is a structure consisting of shareholders, directors, managers, a set of objectives to be achieved by the company, and tools that will be used in achieving goals and monitoring performance. This study aims to determine the application and benefits of Corporate Governance at POSCO, using descriptive qualitative analysis methods. The application of the principles of Corporate Governance at POSCO has been carried out since 1997 through the management philosophy of "Corporate Citizenship: Building a Better Future Together". For example, the principle of equality is carried out by POSCO by making stronger shareholder protection through the Cumulative Voting System to strengthen the rights of small shareholders. The principle of independence is implemented through the separation of share ownership from company management, assigning 7 out of 12 members of the BoD (Board of Directors) to be external directors, and to separate the functions of the CEO and Chairman of the Board. The principle of responsibility is applied through the establishment of an audit committee, the Corporate Social Responsibility program. Corporate Governance had earned POSCO many national and international awards

Abstract

The study purpose was to design and preliminarily validate a universal adjustable workbench that supports seated and standing bench-work activities in educational workshops, overcoming ergonomic limitations of fixed-height benches.Materials and methods. An engineering design–fabrication–testing approach was applied. The prototype was modeled in Autodesk Inventor and built using a manual scissor-lift mechanism actuated by an M10 grade 4.6 threaded bar. The work surface measured 1200 × 700 mm with an adjustable height range of ~75–110 cm. The frame used hollow steel sections (40×40×2.3 mm and 30×30×2 mm; mild steel, σy ≈ 240 MPa) and a double-layer 10 mm plywood tabletop. Actuator capacity was analytically verified using an effective stress area of 58 mm², yield strength 240 MPa, and a safety factor (SF) of 2. Performance evaluation included incremental static loading (100–280 kg), repeated height adjustment (≥50 cycles), and eccentric-load stability testing.Results. The threaded-bar analysis estimated a yield-limit capacity of ~6,276 N (≈640 kg), corresponding to a recommended safe working load of ~320 kg (SF=2). Physical tests up to 280 kg showed stable lifting and height holding with no permanent deformation of the screw or frame; cycle and eccentric-load tests indicated reliable operation under repeated and uneven loading within the tested range.Conclusions. The manual scissor-lift adjustable workbench achieved functional adjustability and demonstrated promising structural stability for workshop/laboratory use. Further work should extend load testing to the recommended safe limit and add quantitative ergonomic posture assessment to substantiate ergonomic benefits.

Abstract

The study purpose was to design, develop, and evaluate an elephant grass chopping machine that integrates a rotary blade mechanism and a pull roll system to improve feeding stability, productivity, and chopping uniformity in ruminant feed processing. Traditional manual chopping methods are labor-intensive, time-consuming, and produce inconsistent particle sizes, which reduce feed efficiency. This research aimed to develop a farm-scale machine with a target capacity of 1 ton/hour that is technically and economically feasible for farmers.Materials and methods. This study used an engineering-based research and development approach consisting of design, fabrication, and performance testing. The prototype was powered by a GX 220 gasoline engine and equipped with strip-type carbon steel rotary blades, a pull roll feeding system, and a pulley–V-belt transmission. Performance testing was conducted using elephant grass at three blade rotational speeds (1,120 rpm, 1,680 rpm, and 2,240 rpm). The observed parameters included chopping time, output mass, chopping capacity, and distribution of chopped sizes.Results. The machine achieved an optimal working capacity of approximately 1,080 kg/hour at a blade speed of 1,680 rpm, meeting the design target. Higher blade speeds reduced processing time and increased the proportion of smaller chopped particles, while lower speeds resulted in longer and less uniform cuts. The pull roll system effectively stabilized material feeding and enabled continuous operation.Conclusions. The developed machine improved labor efficiency, productivity, and feed chopping uniformity, indicating good potential for farm-scale application. However, further design improvements are required to reduce frame vibration, optimize hopper design, and enhance blade mounting safety.
