: A port is one of the places that supports transportation and the country's economy. It functions as the center of the community's economy, used for the purposes of the entry and exit of goods and human activities in it. To be in accordance with its function, a port must have complete facilities. One of the ports that does not meet the criteria mentioned above is the Port of Pota. The port of Pota has not yet operated; one of the reasons is that it does not yet have a stipulation for shipping lanes. The process of making shipping lanes involves dredging in order to get the appropriate depth; it is very important to conduct an investigation of the suspension material. Therefore, research on sediment transport is the basis for the development of port development and aims to be able to determine the hydro-oceanographic conditions in the waters of Pota Harbor. Based on the results of sample testing, it shows that the highest sediment content is at low tide, reaching 0.0087 g/L and the lowest is at high tide, reaching 0.0057 g/L. The simulation results of sediment levels for 24 days show that there is an increase in concentration at Pota Harbor of 0.94 kg/m3. The waters of the Port of Pota have a dominant current direction that tends to be parallel to the shoreline, or it can be said that the currents that occur in these waters are tidal currents. There is a stirring of sediment on the shore, which is then transported by currents and settles as the current velocity decreases due to shallower depths.

: This paper presents a modelling of a high-frequency full bridge inverter for wireless power transmission (WPT) in Electric Vehicle (EV) charging applications. The inverter is designated at an operating frequency as high as 13.56 MHz in line with regulations for the industrial, scientific, and medical radio band (ISM band). Since the power is transferred wirelessly from the source to the EV, a coupling capacitive was used as a transmitter and receiver of the system. In this paper, the inverter model was simulated and analysed using LTSpice software. Different load changes and power are injected into the system. Furthermore, in order to obtain a robust system, the switching frequency of 13.56 MHz is used with some Dead Time (DT). The system already uses GaN MOSFETs for reliability and performance at high frequencies, in addition to LC impedance matching. The result is that by operating at a resonant frequency of 13.56 MHz with a resistive load of 50, it is obtained with a power of 2.3 kW that has been successfully transmitted with an efficiency of 89%.

: The optimal power flow (OPF) issue is a critical optimization job in the operation and planning of power systems. It entails establishing the best settings of control variables to minimize generating costs while meeting operational restrictions. Traditional optimization techniques often struggle to handle the complexities and uncertainties inherent in power systems. This paper introduces fuzzy systems' concepts and their integration with genetic algorithms. It then delves into the many possibilities for power system optimization problems. The first section introduces the fundamental ideas of fuzzy, while the second section explores its structure and components. The third section explores the genetic algorithm's synergism with the fuzzy technique. The suggested technique was evaluated on an upgraded IEEE 30-bus system, with an optimal solution indicating fuel cost reduction under various linear and non-linear constraints. The suggested methodology's results were compared to all those mentioned in the literature. The outcomes of the offered methodologies are encouraging, demonstrating the efficacy and resilience of the proposed procedures. The synergism of the fuzzy system with the genetic algorithm offers several advantages, including flexibility in handling uncertainties, adaptability to complex systems, and the potential for discovering innovative solutions. However, it is important to carefully design the fuzzy system's rule base and appropriately set the genetic algorithm's parameters for optimal performance.

: The paper presents the effect of different temperature measurement configurations of volumed water inside the vessel for the thermal efficiency estimation of liquified petroleum gas stoves (LPG Gas Stoves). For this purpose, initial and final water temperature were measured at nine different configurations, and then the thermal efficiency value at each configuration was determined. The reference test method for energy performance of LPG Gas Stove constituted in Indonesia National Standard SNI 7368:2011 was employed to determine the thermal efficiency of the LPG Gas Stove. A coverage interval method was applied to estimate uncertainties and to reliably compare the thermal efficiency measurement. It is found that the thermal efficiency values of temperature position variations are statically similar to the reference point. The interval level of estimated thermal efficiency values ranges from 2.49% to 2.65%. Furthermore, the temperature measurement is found to be the dominant contributor to coverage interval value of thermal efficiency estimation. Therefore, the temperature measurement of the water volume inside the vessel must be specified in the test method in the standard.

: Indonesia is an archipelago made up of a large number of islands, many of which are small and isolated. For effective connection of the islands, it is crucial to have efficient and well-designed marine transportation systems. High-speed marine vehicles (HSMVs) are suitable for this purpose due to their compact size and speed. As the country continues to grow, the demand for HSMVs is increasing. However, to address the issue of climate change, these vehicles must have technological advancements that increase their energy efficiency. One way to achieve this is through trim control, a technique that can reduce the ship's resistance and improve energy efficiency. Studies have shown that if the trim control is properly configured, it can reduce the effects of ship drag and porpoising. However, the speed parameter, hull characteristics, and return moment capacity of the trim control must be properly configured. Because if the design is incorrect, resistance actually rises in comparison to not employing trim control.

: International cargo transportation is largely dominated by shipping, and it is a crucial aspect. To minimize the negative impact on the environment, ships are expected to abide by strict regulations concerning greenhouse gas emissions. Many shipping companies are turning to Liquefied Natural Gas (LNG) as a primary alternative fuel to reduce these emissions. This is because LNG has been found to have cleaner emissions than traditional fossil fuels. There have been several studies conducted to explore ways to implement LNG as a ship fuel effectively, but there is a lack of research on the specific reduction of greenhouse gas (GHG) emissions from using LNG.

: This study aims to investigate the use of octane booster on pertalite (gasoline with an octane number of 90), analyze the effect of mixed storage time, and compare it with Pertamax (gasoline with an octane number of 92). The selected storage times are 0 weeks, two weeks, and four weeks. This research was started by adding an octane booster to pertalite, and a portion of the pertalite and octane booster mixture was stored for two weeks and four weeks. Samples were characterized by octane number, density, viscosity, torque, and engine power. The results showed that the performance of boosted pertalite increased, then decreased with increasing fuel storage time. The original Pertalite has an octane number of 89.9 and strengthened pertalite at 90.8. Then, after two weeks, it dropped to 90.5, then 90.4 in the fourth week. Pertalite viscosity was 0.630 cP, pertalite boost 0.589 cP, 0.593 cP in the second week, and 0.612 cP in the fourth week. Pure Pertalite 7.54 HP, boosted pertalite increased by 7.80 HP, in the second week 7.69 HP and 7.66 HP in the fourth week.

: A manual calibration system for the solid-state DC voltage standard has been established at the National Measurement Standard (SNSU-BSN). The manual calibration was time-consuming, fatiguing, and difficult to collect data. To improve this measurement process, SNSU-BSN has developed an automatic calibration system for solid-state DC voltage standards using programmable software for data acquisition and a low thermal scanner for switching during the measurement. A differential measurement method is performed for automatic calibration system in 1.018 V and 10 V. This automatic calibration system has been validated with manual calibration mode for measurement repeatability in same environmental condition. The result shows that the standard uncertainties of repeatability for automatic and manual calibration at a nominal voltage of 1.018 V are 0.0035 μV and 0.0071 μV, and for a nominal voltage of 10 V are 0.090 μV and 0.038 μV, respectively. The normalized error (En number) values of nominal voltage 1.018 V and 10 V are less than 1, stating that the results of automatic and manual measurements are in good agreement. Therefore, the automatic measurement system can be applied to replace the manual process of measurement at SNSU-BSN since this method is faster and has better uncertainty values.
