An aluminum composite panel (ACP) is a flat panel with aluminum plates/sheets that are rigid and strong but relatively lightweight. Between the two plates, the core material content is generally made of polyethylene and polyurethane. However, the two core materials are not resistant to high temperatures/heat. They are flammable, so it is urgent to make variations of other core materials resistant to high temperatures. This study aims to provide variations for ACP core materials using polymer materials resistant to high temperatures, namely Low-Density polyethylene (LDPE) and Polyoxymethylene (POM). The method used is experimental/fabrication of ACP making. The high-temperature test was carried out in a furnace with a temperature of 3000C, 3500C, and 4000C, each with a holding time of 1 hour. The results obtained from observing the microstructure using an Optical Microscope before and after the test damaged the core material while the Aluminum metal was still intact. The mass of ACP before and after testing also changed. Overall, at the three temperatures above, the LDPE core material does not withstand this temperature because the temperature is above the melting point of the LDPE material.

Up to 2022, Indonesians will produce 69 million tons of waste, of which 12.5 million tons, or 18.2%, will be plastic waste. Since 1995, the number has been growing dramatically. Recycling shredded waste to reduce its volume and enable processing into other materials is one way to manage plastic waste appropriately. This study specifically converted plastic bottle waste into briquettes for used polymer waste. Briquettes are made from recycled plastic bottles used to make polymer waste. There are two types of briquettes made from this waste: Semi-Bio Briquettes, which are made from recycled plastic bottles that have been used to make polymer waste mixed with natural materials like wood sawdust and coconut fiber and adhered with starch, and Synthesis Briquettes, which are made from recycled plastic bottles that have been used to make patchwork or fabric waste and paper waste. The next tests include (1) the Calorific Value Test (Bomb Calorimeter Method), (2) the Proximate Test following SNI 01-6235-2000, which assesses bound carbon, moisture content, ash content, volatile matter content, and other factors, and (3) the Gas/Smoke Emission Test following 2017 RI Minister of Environment and Forestry Regulation Standards. SEM was used to examine the microstructure of synthetic and semi-bio briquettes. While the calorific values for synthetic briquettes did not satisfy the specifications, the results for semi-bio briquettes met the standards. The proximate test results, however, revealed that the two briquettes did not meet the specifications for bound carbon content while meeting the standards for volatile matter content and moisture level. However, only semi-bio briquettes meet the requirements for ash content. The CO, CO2, and HC gas/smoke emission tests all yielded data that complied with the 2017 RI Minister of Environment and Forestry Regulation requirements. Semi-bio briquettes' microstructure observations were less hollow and denser than those of synthetic briquettes.

Penelitian ini menganalisis pengaruh penggunaan tutup bak dan deflektor angin terhadap koefisien drag (Cd) pada truk menggunakan simulasi terowongan angin. Penelitian meliputi empat konfigurasi: truk tanpa modifikasi, truk dengan tutup bak, truk dengan deflektor angin, dan kombinasi keduanya. Variabel bebas meliputi jenis modifikasi dan kecepatan angin (7 m/s, 8,5 m/s, 10 m/s), sedangkan variabel yang terikat adalah nilai koefisien drag (Cd). Hasil percobaan menunjukkan bahwa kombinasi tutup bak dan deflektor angin memberikan penurunan Cd paling signifikan hingga 34% dibandingkan kondisi tanpa modifikasi, diikuti oleh penggunaan individu tutup bak (16%) dan deflektor angin (24%). Penurunan CD ini mengurangi gaya drag secara signifikan, meningkatkan efisiensi aerodinamika, serta mengurangi konsumsi bahan bakar. Dengan demikian, modifikasi ini direkomendasikan sebagai solusi praktis untuk meningkatkan efisiensi kendaraan niaga dan mendukung ekosistem.

This research explores Underwater Friction Stir Welding (UFSW) on AA6005-T6 material, focusing on identifying optimal process parameters to enhance joint quality in terms of macrostructure, tensile strength, impact strength, and hardness. The results from UFSW welding of AA6005-T6 indicate that optimal process parameters yield better joint quality. The macrostructure of specimens with optimal parameters, such as spc 7, demonstrates improved homogeneity and minimal defects. The highest tensile strength and impact strength were achieved in this specimen, with a tensile strength of 117.7 MPa and an impact strength of 0.944 joule/mm², compared to other specimens. Meanwhile, the hardness of the welded joints, which is lower than the base metal, reflects the influence of process parameters on the microstructure of the joints. Overall, these results underscore the importance of precise parameter control to achieve high-quality welds. This research provides valuable insights into the effectiveness of process parameters in producing high-quality joints in underwater welding environments and highlights the potential of UFSW as an innovative method for underwater welding.

The purpose of this study is to convert tofu wastewater into biogas using an anaerobic digester with varying cow dung mixtures (10%, 15%, and 20%). The study method entails creating digesters including independent, dependent, and controlled variables. Variations in pH, temperature, biogas pressure, and biogas volume were detected throughout the course of a 15-day fermentation. The data show that in the 10% fluctuation, the greatest pH was on day 7 (7), whereas the highest temperature was 32°C on days 6 and 7. Biogas pressure emerged on day 6 (89.2 cmHg), resulting in a volume of 90 liters by day 15. In the 15% variation, the highest pH (7.2) occurred on day 8, with the highest temperature (34°C) on days 9 and 10. Biogas pressure began on day 5 (89.9 cmHg), with a biogas volume of 95 liters on day 15. The 20% variance resulted in the highest pH (7.4) on day 8 and the highest temperature of 35°C from days 9-11. Biogas pressure began on day 5 (90.7 cmHg), resulting in a biogas volume of 100 liters on day 15. This study sheds light on how to manage tofu waste into biogas with varying degrees of effectiveness and efficiency.

For the manometer that will be used in this study, using a U column type manometer filled with a fluid for measuring pressure, this manometer was designed using a simple tool at the time of manufacture. This manometer will be tested for its level of accuracy in the Head Losses test on the piping system. That is by using 3 types of fluids, namely resin, glycerol, and mercury where the pressure is generated from the flow of water in a straight pipe and an Elbow where this Manometer is placed in a straight pipe and also in the Elbow so here using 2 Manometers for testing. Then the test is carried out according to the specified variables, in order to obtain research data. After that determine the results of the pressure measurement of the 3 types of fluids used. The pressure measurement uses water discharge measuring 20, 15, and 10L/min. Then determine each result from each fluid where each fluid is experimented 3 times to determine the average value. If you have obtained the average value of each height difference (∆h) in each fluid, then determine the pressure value (Pa). The results of the Head Losses test on the piping test show that the resin value is close to the mercury value while the glycerol value is quite far. This shows that the density value of each fluid has an influence on the pressure value of each fluid. Keywords – Manometer; Pipe; Pressure; Head losses; resins; Glycerol; Mercury

The implementation of an automatic lathe, utilizing hydraulic drive and PLC programming, stands as a significant advancement in industrial engineering aimed at augmenting productivity while circumventing additional labor requirements. Through meticulous research, it was discerned that the predominant issue plaguing the production process was the occurrence of stoppages due to irregular or unstable dimensions in the output, particularly concerning the Item Bush K0JA Left. Employing methodologies such as SIPOC analysis and the 4M framework revealed that the root cause primarily stemmed from machine-related factors, exacerbated by fluctuations in the installation, resulting in misalignments and subsequent dimension inaccuracies. Addressing this, a targeted intervention involving the addition of locking bolts to the material fixture mitigated the stoppage occurrences significantly, with the operator rectifying positioning irregularities on average 1200 minutes per month. This intervention not only enhanced operational efficiency but also yielded tangible cost savings, amounting to Rp 578,000 monthly or Rp 6,936,000 annually, attributed to the prevention of production downtime. The implications of this study underscore the importance of proactive measures in streamlining manufacturing processes, thereby optimizing resource utilization and economic viability. Further research avenues could delve into the optimization of maintenance protocols for automated machinery and the exploration of advanced sensor technologies to preemptively detect dimensional inconsistencies, thus bolstering overall production resilience and efficacy. Highlight: Advanced machinery integration boosts manufacturing efficiency. Root cause analysis reveals process optimization insights. Cost savings demonstrate practical impact of production enhancements. Keywoard: Automatic lathe, Industrial engineering, Productivity enhancement, Dimensional accuracy, Cost savings
