<![CDATA[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.]]>

<![CDATA[This research develops a smart doorlock system for engine rooms and platforms based on RFID technology and the Arduino platform. This system is designed to increase security and efficiency in managing access to important areas on a ship or industrial installation. The method used involves the integration of an RFID module as an authentication medium and an Arduino microcontroller as the system control center. Users can open the door simply by holding the registered RFID card close to the RFID reader, which then sends a signal to the Arduino to activate the door lock mechanism. This system is also equipped with an access data recording feature that allows real-time monitoring and review of incoming and outgoing activities. Test results show that the system functions well in various scenarios, demonstrating high reliability and responsiveness. Thus, this RFID and Arduino based smart doorlock system can be an effective solution in improving security and access control in critical environments.]]>

<![CDATA[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).]]>

<![CDATA[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.]]>

<![CDATA[IPAL sludge in the Industrial Estate until now has not been able to be utilized properly, the utilization of IPAL sludge into flower pots is one of the efforts to overcome the problem of IPAL sludge waste. The purpose of this study was to determine the variations in each experiment, the characteristics of flower pots from IPAL sludge in each experiment, and the difference in ratios in each experiment. The method used is the solidification methods, which is the process of adding materials that can solidify waste to form a solid waste mass. Experiments were conducted with different mixtures of old newspapers, water, and cement to produce optimal flower pots. Of the three experiments that have been carried out, all experiments were carried out successfully and obtained the same ratio results, but have different characteristics. The implementation of this method is expected to be an example of sustainable waste management and provide benefits to the environment and society, and has the potential to support farming activities and can be a superior product in the handicraft business.]]>

<![CDATA[Waste sludge is sludge that contains a lot of solids resulting from solid-liquid separation from industrial waste. The waste sludge produced from the waste processing process will create new problems in handling because it can pollute the environment. This research will discuss the use of IPAL sludge originating from the Sludge Drying Bed (SDB) to be used as organic fertilizer. In the process of making organic fertilizer in the cake and snack industry by monitoring parameters such as color, texture, smell and properties of organic fertilizer during the process of making organic fertilizer. The characteristic results obtained in this research are blackish brown color, rough texture, earthy odor and the resulting moisture is dry. Thus, the use of WWTP sludge as organic fertilizer offers an innovative and industrial solution that contributes positively to the environment.]]>

<![CDATA[The main purpose of this study is to investigate in depth regarding the planning of electrical panels to be used in elevator systems. The method used is a literature study followed by the creation of panels and data collection. This process starts from the initial stage, namely making drawings of the electrical panel series, then continues with construction planning and installation of the overall elevator system. Selain itu, pengecekan berkala terhadap kualitas lift yang dipasang juga menjadi fokus utama dalam penelitian ini. This is important to ensure that elevators operating in these tall buildings can maintain safety and comfort when used by people and in the process of transporting goods to various floors of the building. Thus, it is hoped that the results of this study can make a meaningful contribution in improving the efficiency and safety of vertical transportation within modern high-rise buildings.]]>

<![CDATA[Rotary drilling is one of the drilling methods that is often used for stripping overburden in open pit mining activities. In the rotary drilling process, prediction of the penetration rate is very important for scheduling production and estimating drilling costs. Drilling in mining activities is used, among other things, to create blast holes. In blasting activities, drilling is the first activity that must be carried out to provide a blast hole which will later be filled with explosives to be detonated. Meanwhile, the speed at which the blast hole is prepared is influenced by the speed of the drilling tool to penetrate the rock. Drilling speed is influenced by two factors, namely internal factors and external factors.]]>
