Abstract

Distillation is a water purification process through evaporation and condensation. Research on solar distillation was developed using the Computational Fluid Dynamic (CFD) method to obtain an overview of the transmission of solar radiation heat by the cover glass for variations in the angle of the glass inclination of 100, 200 and 300. The water height in the basin is 100 mm. The simulation results show that the heating process with variations in the angle of the cover glass affects the distillation results. The smaller angle of the cover glass inclination, the higher heat flux entering the basin so that the evaporation process becomes higher which ultimately increases the amount of distillate water production produced. The highest heat flux entering the distillation system was achieved by the system with a cover glass inclination angle of 100 with a value of 388.525 W / m2, while the lowest was at an angle of 300 with a value of 379.792 W / m2. In addition, the highest distillate production was obtained on the cover glass with an inclination angle of 10 ° of 1.078 cc. For operational hours at 13.00 WIB and simulation time 180 seconds.

Abstract

PT ABC is a wheat flour production company in Indonesia. Many sophisticated machines are used in the wheat flour production process, one of which is the roll mill machine. In its operation, the roll mill machine uses bearings to support the roll when it rotates and reduce friction that occurs so that the roll can rotate smoothly and avoid wear. If the bearing does not function properly, it can damage the machine and other components. Therefore, to predict damage to the bearing, it is necessary to analyze how long the bearing lifetime is. In the implementation of this Practical Work, research will be conducted to determine the lifetime and types of damage that occur to the bearings used so that solutions can be found to prevent damage to the machine and other components. Based on the results of calculations in this study, the life of the spherical roller bearing in the roll mill machine using the basic rating life method shows that the bearing life obtained is 36,696,343 operational hours, while the time required to re-lubricate the spherical roller bearing is every 9800 hours with the amount of lubricant given is 17.6 grams.

Abstract

One of the important components in the power generation process at the Suralaya PGU PLTU is the Gate Valve. The MOV 30 Gate Valve is a valve that functions to regulate the flow of steam gas from the extraction steam to the blow down tank. Preventive maintenance on the MOV 30 Gate Valve unit 7 aims to prevent unwanted damage, reduce the risk of failure, and ensure that the device operates with maximum efficiency. With proper preventive maintenance, PT Indonesia Power hopes to avoid disruptions in power generation operations, minimize downtime, and extend the operational lifespan of the equipment. Damage to a gate valve can be caused by several factors, including excessive pressure in the valve flow, high temperatures passing through the valve, and friction forces when opening and closing the valve.

Abstract

Adhesive technology has seen significant advancements in recent years. Compared to welding or threaded joints, adhesives provide a straightforward mechanism for joining material interfaces. Due to practicality allows for the potential development of adhesives with strengths comparable to those of traditional joints. In this study, a modified type of Polyvinyl Acetate (PVAc) adhesive was utilized as a binder for mahogany wood surfaces. The choice of PVAc adhesive is due to its common use in everyday applications, particularly in the woodworking industry. Additionally, this adhesive is relatively safe for both health and the environment. The study examined three types of adhesives: PVAc white adhesive, PVAc yellow adhesive, and a combination of the PVAc white and yellow adhesive. These adhesives were used to bond the wood surfaces, and the bond strength at the interface was evaluated through a flexural test. The results showed that the adhesive strength of white adhesive reached 111 MPa, while the mixed adhesive and yellow adhesive exhibited flexural strengths of 74.2 MPa and 63.4 MPa, respectively. Notably, the presence of white glue was found to enhance the flexural strength of mahogany wood even in the absence of adhesive.

Abstract

Roof tiles play a vital role in the construction industry by providing protection from the sun's heat and rain. The quality of roof tiles largely depends on the materials used and the manufacturing process, as these factors significantly affect the tiles' mechanical properties. Kangkung pagar (Ipomoea carnea) is one type of alternative natural fiber material that can be utilized in the creation of composite materials. This study aims to explore the potential of Ipomoea carnea powder as an alternative material for producing polymer roof tiles, as well as to examine how variations in the composition of powder and sand influence the mechanical properties of these tiles. The method for producing roof tiles is based on powder metallurgy. The composition of the powder and sand used varies in the following ratios: 10% powder to 50% sand, 20% powder to 40% sand, and 30% powder to 30% sand. Additionally, a fixed composition of 30% polyester resin and 10% asphalt is used. The initial process involves mixing the materials according to these predetermined ratios. The resulting mixture is then molded and compacted under a pressure of 200 kg/cm². Characterization of the mechanical properties includes proximate analysis, calculation of porosity and density, flexural strength testing, and hardness testing.The study's results indicated that the properties of polymer roof tiles are significantly influenced by the composition of the powder and sand used during their manufacture. The findings revealed a porosity value of 0.209%, a density of 0.994%, a flexural strength of 2.270 MPa, and an optimum hardness of 19.1 BHN. The addition of 10% powder increased the hardness value by only 0.4% while decreasing the flexural strength by 0.5%. Overall, the use of Ipomoea Carnea powder was not effective in enhancing the mechanical properties of the polymer roof tiles, as both the flexural strength and hardness values remained below those of commercially available polymer roof tiles.

Abstract

Karangantu Port, located in Banten Province, plays a strategic role in supporting capture fisheries activities. However, fishing vessels operating in this port often face hydrodynamic resistance issues that affect operational efficiency. This study aims to analyze the influence of vessel speed and draft on the total resistance experienced by fishing boats. A 3D hull model was developed using SolidWorks and simulated using Maxsurf. Speed variations ranged from 5 to 12 knots, with four draft levels tested: 0.5 m, 0.7 m, 0.9 m, and 1.1 m. The results show that total resistance increases significantly with speed, particularly due to the dominance of wave-making resistance at speeds above 8 knots. Deeper drafts also lead to higher frictional resistance, caused by the increased wetted surface area. The optimal operational speed for maintaining fuel efficiency is in the range of 6 to 9 knots, with a balanced draft setting to ensure vessel stability without excessive resistance. These findings are expected to contribute to more efficient design and operation of fishing vessels at Karangantu Port.
