Abstract

Dalam penelitian ini adapun tujuan yang diharapkan terkait dengan analisis perhitungan head pompa sentrifugal pada rangkaian seri dan paralel yaitu untuk mengetahui perbandingan nilai head total pompa dari dari masing-masing rangkaian, serta untuk mengetahui perbandingan dari hubungan head (m) terhadap bukaan valve dan juga hubungan head loss terhadap bukaan valve. Proses pengujian dilakukan dengan menggunakan dua pompa sentrifugal tipe 1 ½ BA-6 dengan jenis fluida kerja yang dipakai ialah air pada temperatur ±30?C. Dari hasil penelitian yang telah dilakukan didapatkan suatu hasil data analisis dari perhitungan head total pompa,  dimana nilai head total pompa seri untuk bukaan katup penuh sebesar 38,79 m dengan debit aliran 0,00325 , bukaan katup 2/3 nilai head total sebesar 46,14 m dengan debit aliran 0,00323  dan bukaan katup 1/3 nilai head total sebesar 50,16 m dengan debit aliran 0,00306 . Sedangkan pada pompa paralel diperoleh nilai head total dari bukaan katup penuh sebesar 27,7 m dengan debit aliran 0,00375 , bukaan katup 2/3 nilai head total sebesar 32,6 m dengan debit aliran 0,00374  dan bukaan katup 1/3 nilai head total sebesar 37,9 m dengan debit aliran 0,00367 . Dari hasil data yang diperoleh dapat diambil kesimpulan bahwa adanya kenaikan nilai head total terhadap variasi pengaturan bukaan valve yang mana nilai head total tertinggi terdapat pada bukaan valve 1/3. Dan dari kedua jenis rangkaian terlihat adanya penurunan nilai head total seiring juga dengan bertambahnya nilai debit/kapasitas pada pompa. Sehingga hubungan antara head total dengan debit adalah berbanding terbalik, dimana nilai head  terendah diperoleh pada debit yang paling besar.

Abstract

During the Covid-19 pandemic, the tourist village of Sumbergedang, Pandaan Pasuruan, experienced a drastic decrease in visitors, which greatly reduced their income. Meanwhile, in the village, water from the mountains is very abundant. Purpose and solution offered is to manage clear water in the village using Simple Appropriate Technology, namely making a tubing tube to fill the clear water which will later be processed into clean water. The clean water produced is ready to drink, and this will be a separate effort to increase the income of residents in the tourist village of Sumbergedang during the Covid-19 pandemic

Abstract

The chassis is an important component car which functions to support the load on the vehicle and has a strong construction. The chassis, as the main support for all vehicle componentsy. Increased fuel use and rising global crude oil prices have encouraged research into energy saving cars with special designs that can reduce fuel consumption and pollutant emissions. The design process with variations in rollbar shape and variations in cross sectional shape with 6061 aluminum material using Autodesk Inventor 2024 software. After the design process is complete, stress analysis test stage is carried out to obtain analysis data, namely von misses stress, strain, displacement, safety factor. The results of the chassis design using concept B with a pipe cross-sectional shape and rollbar fillet model are more recommended, because it has better von Mises stress value and a better safety factor, besides that the concept B chassis design is easier in the assembly process with prototype type energy efficient car body.

Abstract

The need for clean water increases every year, while the means to provide clean water require planning. The importance of water in the realm of education is comparable to that of household needs. Water on the 3rd and 4th floors of Building A often doesn't flow. The aim of this research is to identify the root cause of the insufficient water flow on the 3rd and 4th floors of Widyatama University Building A, and to devise a solution for the water flow distribution system. The research employs a variety of methods, including literature review, data collection, data analysis, results analysis, and interpretation. The conclusion is that the water drainage on the 3rd and 4th floors is 0.612 L/s and 0.510 L/s, which is below the standard (0.9–2 L/s). The drainage of water in the main pipe was uncertain based on its diameter. The solution to this problem is to install booster pumps on the 3rd and 4th floors. The next solution is to change the main pipe diameter to 1 1⁄4".

Abstract

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.

Abstract

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.

Abstract

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.
