Abstract

The coal feeder motor is a three-phase induction motor whose speed is regulated by the Variable Speed Drive (VSD). The coal feeder motor functions as a medium for distributing coal fuel to the combustion chamber in the boiler which aims for the combustion process in heating water on the pipe wall (wall tube) which will be used as steam to drive the turbine. Before supplying coal, first pay attention to the amount of coal entering the coal feeder, because it will affect the coal flow and motor performance. The more coal that enters the coal feeder, the greater the coal flow, just as the high speed of the motor will increase the flow of coal entering the furnace. From the research results, the calculation of the change in motor speed to the torque of the coal feeder motor at a speed of 115.2 rpm obtained a torque of 7.88 Nm, at a speed of 144 rpm obtained a torque of 6.68 Nm, at a speed of 230.4 rpm obtained a torque of 5.33 Nm and at a speed of 288 rpm obtained a torque of 4.48 Nm%. at a speed of 115.2 rpm an efficiency of 31.05% was obtained, at a speed of 144 rpm an efficiency of 29.55% was obtained.

Abstract

Power system stability is a critical factor in maintaining the continuity and quality of energy supply, especially in transmission systems that face load fluctuations and integration of renewable energy sources. The main problems in this study are voltage instability and reactive power oscillations that often occur due to disturbances such as sudden load changes or short circuits, as well as the limited capacity of conventional controllers in reducing these impacts. This study aims to explore the role of Static VAR Compensator (SVC) as part of Flexible AC Transmission Systems (FACTS) technology in improving transmission system stability through a qualitative approach. The research method is carried out with descriptive analysis based on literature studies, mathematical modeling of the power system, and numerical simulations to understand the dynamics of the system response to disturbances. The focus is given to qualitative evaluation of the interaction between SVC, system parameters (voltage, reactive power, and phase angle), and the impact of controller placement on network reliability. Simulation case studies cover small to large disturbance scenarios to assess the effectiveness of SVC in restoring stability. The results show that SVC integration makes a significant contribution to improving the dynamic stability of the transmission system. Qualitative analysis finds that SVC is able to reduce voltage oscillations and accelerate post-disturbance system recovery through adaptive reactive power regulation. However, the limited capacity of SVC in handling extreme disturbances indicates the need for combination with other FACTS controllers (such as STATCOM or UPFC) for more complex systems. This study also reveals the importance of proper SVC placement strategy to optimize its effectiveness.

Abstract

Electricity is a very important need, especially in the field of information technology development, educational facilities and households. The application of alternative electrical energy sources as backup energy by utilizing DC (direct current) energy sources from batteries (accu) which are converted through circuit stages so that they can be used as AC (Alternating current) backup energy sources. PLN electricity used to charge the battery (charge) through a step down transformer to 24Vac then rectified through a rectifier circuit in the form of a bridge rectifier aims to rectify the AC voltage to a DC voltage of 24Vdc to charge the 24Vdc battery. This automatic charger test aims to obtain the performance of the circuit that will cut off the charging current at a voltage of 13.5V on a 12V battery with a capacity of 5AH automatically when the battery is fully charged. Where the battery input comes from the rectifier output of 13.5V and the battery output will be used as input from the inverter. Before the automatic Charger circuit is connected to the battery, the battery input voltage is set at 11.5Vdc. Charging the charger produces a voltage of 13.5 volts with a maximum charging current of 1.17Amperes with a charger time of 2.5 hours, the charging process from a voltage of 11.5 Volts increases to 13.5 Volts. The temperature of the battery when charging must also be monitored so that there is no excessive heat that can damage the battery cells which reduces the life of the battery.

Abstract

The bilateral investment relationship between Indonesia and Japan has been crucial in fostering economic cooperation, particularly under the Indonesia-Japan Economic Partnership Agreement (IJEPA). However, IJEPA which has been enforced since 2008 has encountered implementation challenges, such as specificity in addressing modern investment challenges, regulatory changes, environmental concerns, and labor mobility, particularly in the caregiving sector. This research explores the possibility of establishing a Bilateral Investment Treaty (BIT) between Indonesia and Japan to bridge the gaps within IJEPA and strengthen bilateral investment relations. The research employs a normative legal approach, to analyze legal documents, treaties, and secondary sources to assess the feasibility of a potential BIT in bridging IJEPA. The study identifies key principles that should be included in the proposed BIT, such as clear definitions of Fair and Equitable Treatment (FET), Most-Favored-Nation (MFN) clauses, and dispute resolution mechanisms that balance investor protection with state sovereignty. Additionally, the thesis highlights the importance of sector-specific provisions tailored to the automotive industry, labor mobility (especially for caregivers), and green energy projects, which align with the strategic interests of both nations. The findings suggest that a new BIT between Indonesia and Japan is both feasible and necessary to enhance bilateral investment relations. The proposed treaty would provide greater legal certainty, encourage long-term investment, and address the shortcomings of IJEPA. By incorporating updated provisions on investor protection, labor rights, and sustainable development, the BIT would foster a more stable and predictable investment environment, benefiting both countries economically and socially.
