Abstract

One of the greatest potentials of renewable energy is solar energy, which can produce electricity. The industry welcomed this to utilize solar energy to produce electricity through a PV rooftop system. The advantage of PV rooftops in producing electrical energy is in terms of investment costs that can eliminate the land component because it utilizes the roof of an industrial building as a place for PV rooftops to produce electrical energy. Soy Sauce companies, as one of the industries engaged in food, can utilize a PV rooftop with 300 kWp to produce electricity. The electrical energy produced by the PV rooftop can reduce 17,23% of the total electrical energy consumed by soy sauce companies in one day from PT. PLN electrical energy sources. A rooftop PV investment capacity of 300 kWp has a payback period of 12 years with an IRR value of 7% and a lifetime of using PV rooftop for 25 years.

Abstract

The cooling system is a medium that serves to absorb heat. The heat is obtained from the combustion of fuel in the cylinder. engine cooling is intended to maintain a stable temperature in the engine so that there is no too high temperature increase as a result of the combustion of fuel in the cylinder and the friction that occurs. Cooling the engine is also intended to reduce the risk of damage. The diesel engine cooling system is divided into 2, namely a closed cooling system and an open cooling system. The open cooling water system has an average temperature of 300 Celsius and the closed cooling water system has an average inlet temperature of 400 Celsius and an outlet temperature of 700-800 Celsius. Problems that often occur in the cooling water system are broken shaft impellers for seawater pumps, pipe leaks and capillary pipes clogged with dirt. The results of the writing refer to the damage to these components, this causes the fresh water temperature to rise. Therefore, regular and systematic maintenance and repair of these components is absolutely necessary for the cooling system to work optimally.

Abstract

River and lake traffic signs play an important role in maintaining the safety of water navigation, but there is still a lack of understanding and supporting technology to recognize them automatically. This study aims to compare the performance of two popular object detection methods, namely YOLOv7 and Single Shot Multibox Detector (SSD), in identifying river and lake signs based on digital images. The dataset used consists of 6,650 images, including original data and data that has been augmented with visual degradation such as low resolution, noise, blur, lighting artifacts, occlusion, and cluttered background. This study evaluates the models based on accuracy, precision, and recall metrics. The test results show that YOLOv7 excels in all metrics, with the highest accuracy of 78%, compared to SSD which only reaches 70%. Both models experience a significant decrease in performance under occlusion and cluttered background conditions, but YOLOv7 still shows better resilience. Meanwhile, the blur condition is the degradation that least affects the performance of both models. These findings confirm that YOLOv7 is more robust to visual disturbances and can be a more effective alternative in automatic river and lake traffic sign recognition systems.

Abstract

The development of the utilization of electrical energy sourced from the sun is currently experiencing very rapid development. The use of electrical energy sourced from the sun is not only used for industrial generation, currently the transportation industry also utilizes electrical energy sourced from the sun for propulsion and domestic needs. This study discusses the potential of electrical energy that can be generated by solar PV with a capacity of 2x550 Wp which will be implemented on cadet training ships. Solar irradiance is the most important component for the process of generating electrical energy, where later the irradiance value will become electrical energy using solar PV media. The irradiance value is obtained from a web application called solarglobalatlas which already has big data about the irradiation value in various places. This study took irradiation values in the coordinates area -2.953161°, 104.886022° (-02°57'11", 104°53'10") South Sumatra. The data was taken for 12 months to ensure that the data radiation experienced two seasons according to the characteristics of the area. The best irradiance values occur at 11.00 am – 01.00 pm. The results of the discussion show that the annual electrical energy that can be generated by solar PV with a capacity of 2x550 Wp using the monocrystalline PV type is 1,338.2 kWh with the largest electricity production peak occurring in August of 114.4 kWh. Meanwhile, the smallest production of electrical energy occurred in February at 87.2 kWh.
