Abstract

In the era of maritime technology, Unmanned Surface Vehicles (USVs) are becoming the main vehicles on the water surface, controlled from land and capable of transmitting live data. USVs have a wide range of survey and exploration applications, relying on hydrographic knowledge for accurate mapping. USV development has adopted a double hull design, improving stability and wave resistance. Survey data transmission requires advanced technology, with Long Range (LoRa) technology being the solution for long distance data transmission with low power consumption. LoRa utilisation is expected to increase the efficiency of USVs in hydrographic surveys. The research and development (R&D) research method is used as the main approach in this research with the aim of creating and developing USVs that can increase efficiency in hydrographic surveys. The USV is equipped with an RPM sensor and flowmeter used to monitor the movement control of the USV in the waters. In addition, a depth detector is used to monitor the topography of the seabed. In order for this USV to run using a remote control that is controlled from land. The USV drive consists of a BLDC motor connected to the propeller and a servo motor connected to the ship's rudder. Furthermore, the data taken from the sensor is sent via LoRa to be delivered to the ground station. From the USV test results, it was found that the data transmission range with LoRa Ra-02 under Line of sight (LOS) conditions was 340 metres while under Non Light of sight (NLOS) conditions it was around 200 metres. The average speed travelled by USV is 0.616 km/hour in operational survey conditions and can be faster in non-operational survey conditions. The error value of the RPM sensor is obtained at 1.604% with a reading accuracy of 98.936%.

Abstract

The impact of the increase in motorized vehicles is air pollution from vehicle exhausts. Exhaust gas is a polluting substance that pollutes the air where the gas is created from exhaust gas or gas from the combustion of vehicles. One alternative way to reduce the content of harmful exhaust gases such as carbon monoxide (CO), and hydrocarbons (HC) produced by motorized vehicles is by adding a catalytic converter. In this study, the catalytic converter uses Aluminum (Al), Brass (Cu-Zn), and Copper (Cu) materials. The purpose of this study is to analyze the effect of using a catalytic converter made of Aluminum (Al), Brass (Cu-Zn), and Copper (Cu) on exhaust gas. In addition, this study aims to determine the material used as a catalytic converter in order to get the lowest level of exhaust gas. Furthermore, the research data are presented in tabular form and then analyze them using one way anova and graphs. The results showed a decrease in CO by 50% at 1500 Rpm and 59.6% at 4500 Rpm, HC by 72% at 1500 Rpm and 55% at 4500 Rpm, CO2 by 3.22% at 1500 Rpm and 7.91% at 4500 Rpm, and O2 by 5.53% at 1500 Rpm and 1.66% at 3000 Rpm.

Abstract

Sludge is a by-product of an activity that comes from the discharge outlet of the flocculation, sedimentation and backwash filtration basins. To determine the volume of sludge contained in one liter of raw water, it is necessary to conduct a Jartest Test by determining the optimum dose of PAC. This water sampling was carried out at the Krian 1 Water Treatment Plant (IPA). Primary data collection is obtained from Imhoff Cone Results data. While for secondary data collection we get from Jartest data. The manufacture of the coagulant solution used is Poly Aluminum Chloride (PAC). The average turbidity value in February was around 123 NTU and there was an increase in turbidity on the seventh day which reached 237 NTU. The drastic increase in turbidity reached 455 NTU with an average turbidity in March of 130 NTU. The graph shows that there is a significant correlation between the volume of sludge produced during the treatment process and the level of water turbidity. Thus, the researcher suggests further treatment of the remaining sludge which can be done by making a Sludge Drying Bed (SDB).

Abstract

This study aims to analyze the effect of macro fundamentals, capital structure, ownership structure on firm value with profitability as an intervening variable in agri-food companies listed on the Indonesia Stock Exchange from 2014 to 2023. This research uses documentation studies as a data collection technique and for data processing, Smart-PLS (Partiral Lerast Squarers) is used. The results show that capital structure has a significant influence on firm value, while ownership structure does not show a significant influence. In addition, profitability is proven to be an intervening variable that strengthens the relationship between capital structure and firm value, but does not strengthen the relationship between firm size and firm value. These findings provide important implications for the management of Agri-Food companies in making decisions related to financing and ownership strategies to increase firm value.
