Abstract

In Madiredo Village, which is located in Pujon District, Malang Regency, there are many business programs. The problem is that these efforts result in a wide range of waste, including up to 5 tons per day of residential waste and other corporate waste. The debris was gathered from the Bengkaras Hamlet, Madirero Village Reduce, Reuse, Recycle (TPST 3R) Integrated debris Management Site. However, a lot of plastic garbage has still leaked out of the packing. The objective is to create a press machine (press) with an electric motor so that packed plastic trash and levers (used when the power goes out) no longer require manual work. The process involves designing and producing waste press machines, particularly for cardboard, plastic trash, and old bottles. Use of the 2016 version of Solidworks for the simulation design. The lowest stress, 2.038 x 104 N/m2, and the highest Von Misses stress, 2.825 x 108 N/m2, are determined by the modeling findings. The biggest displacement or deflection is 1.737 x 10 mm, while the smallest displacement is 0 mm. The values of the strain range from 1.880 x 10-7 to a minimum of 6.00 x 10-4. Safety factor has a value greater than 1 A 1 horsepower AC motor is used in the press machine's construction. Three different distance stopper pressing variables—33 cm, 35 cm, and 37 cm—as well as various types of waste plastic bags, plastic bottles, and cartons/cardboard are used to test the pressing performance. The results show that pressing plastic trash at a distance from the pressing stopper of 37 cm, a mass of 167 kg, a time of 2.2 minutes, and a compressive force of 6546.4 N/m2 may pack or package well for garbage in plastic bags

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

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.

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.

Abstract

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.
