Abstract

Polyethylene terephthalate (PET) plastic bottle waste can be recycled into 3D printer filament through pultrusion method. Some previous studies have identified the parameters of PET recycled filament, but have not yet deeply examined the effect of the combination of parameters including the level of roughness. This study aims to evaluate the effects of variations in bed and head temperatures and printing speed on the dimensions of 3D-printed PET filament, to analyze defects, and to assess surface roughness. The results showed that the best products were found at a head temperature of 265°C, a bed temperature of 80°C, and a speed of 35 mm/s. The dominant defects that appeared were under & over-extrusion, weak infill, and layer separation and splitting. Minimal defects were obtained at a head temperature of 265°C and 260°C with a bed temperature of 80°C at a speed of 35 mm/s. The lowest surface roughness results were in class N10, namely Ra = 16.137 µm. This study indicates that optimized parameters produce high quality, making PET a sustainable alternative material.

Abstract

As a tropical country, Indonesia has abundant biomass potential because plants grow all year. Among the several types of biomass, nyamplung kernel cake (NKC) has a high potential for use as an energy source. The goal of this research was to develop a biomass burner and evaluate its performance using NKC and wood pellets (WP) as comparisons. The burner performance test is designed to investigate the effect of air mass flow rate on combustion flame, heat release rate, and thermal efficiency for both types of biomass. The thermal efficiency of the burner was calculated using the water boiling test (WBT). The results revealed that using NKC resulted in a longer combustion flame at air flow rates of 146 and 219 g/s. The higher the air flow rate, the longer the flame. The combustion of NKC and WP produced the longest flame, measuring 80 cm with an air mass flow rate of 290 g/s. The experiment also demonstrated that WP produced a higher temperature than NKC. The highest combustion temperature was produced by WP, reaching 818.1°C with an air mass flow rate of 290 g/s. From the two types of biomass evaluated, WP combustion produced more heat than NKC. The highest heat release rate of 35.46 kW was achieved with an air mass flow rate of 290 g/s. The burning of NKC resulted in the maximum thermal efficiency, 30.35% at an air mass flow rate of 219 g/.

Abstract

The braking system is a critical component in ensuring the safety of motor vehicles. Braking effectiveness is influenced by the condition of the braking components and supporting factors such as tire type and air pressure. Inappropriate selection of tires or incorrect air pressure can reduce tire grip on the road surface, leading to decreased braking efficiency. Based on this background, this study aims to analyze the effect of variations in tire type (bias and radial) and tire air pressure on the braking efficiency of the Isuzu TBR 54 vehicle. The research was conducted at the Motor Vehicle Testing Unit of the Department of Transportation in Magelang City using an experimental method. A Certus 2023 brake tester was employed to collect data. The variables tested included two types of tires and five different air pressure levels (25, 30, 32, 35, and 40 psi). Braking force data on both vehicle axles were collected and analyzed using SPSS software through normality tests, homogeneity tests, and t-tests to determine the significance of each variable’s influence. The results showed that tire type and air pressure significantly affect braking efficiency. Radial tires demonstrated better braking performance than bias tires across all pressure levels. Excessive air pressure reduced braking efficiency due to a decrease in the tire’s contact area with the road surface. The most optimal combination for braking efficiency is achieved with radial tires at an air pressure of 25–30 psi, which results in braking efficiency above 75%. These findings highlight the importance of selecting the appropriate tire type and maintaining proper air pressure to enhance vehicle safety and braking performance.

Abstract

Metal-air batteries are rechargeable secondary batteries with high energy density, typically using carbon electrodes. However, carbon waste poses environmental risks. Fly ash, a byproduct of coal combustion, offers a sustainable alternative due to its high electrical conductivity. This study analyzes research trends on metal-air batteries and fly ash from 2019 to 2023 using bibliometric visualization of Scopus-indexed publications. The keyword search was refined from 'Battery' to 'Air Battery' and, finally, 'Air Battery' with 'Fly Ash,' yielding 60 relevant articles. Using the VOSviewer, research patterns, key focus areas, and collaboration networks were identified. The results indicate a 14.87% increase in publications from 2019 to 2023, with significant growth from 2019 to 2021 before declining after 2022. This fluctuation suggests shift in research interests toward other battery technologies. Fly ash demonstrates potential as a carbon substitute for air batteries, promoting sustainability. However, further research is needed to optimize its application and address technical challenges. Bibliometric visualization highlights a growing interest in fly ash for environmentally friendly battery development due to its abundance and sustainability.

Abstract

Seiring dengan bertambahnya jumlah penduduk dan pertumbuhan ekonomi, maka terjadi peningkatan timbunan sampah di hampir semua kota di Indonesia. Sementara kondisi tempat pembuangan akhir (TPA) sampah saat ini sudah atau hampir penuh, sehingga tidak bisa menampung sampah lebih banyak lagi. Oleh karena itu, perlu ada solusi jangka pendek untuk menjawab permasalahan kedaruratan sampah ini. Kajian ini menganalisis beberapa teknologi alternatif yang dapat digunakan untuk mengolah sampah padat perkotaan menjadi sumber energi. Dari hasil review, teknologi termal merupakan proses yang paling cepat dan meninggalkan residu yang paling sedikit. Teknologi termal yang dapat diterapkan yaitu pembakaran/insinerasi, gasifikasi, dan pirolisis. Teknologi insinerasi dapat digunakan pada skala besar karena melibatkan proses yang menggunakan ketel uap (boiler) dan turbin. Sementara gasifikasi lebih cocok diterapkan pada skala yang lebih kecil dengan menggunakan mesin gas atau mesin diesel sebagai pembangkit listriknya. Sedangkan pirolisis lebih sesuai untuk jenis sampah homogen dan tertentu seperti plastik dan ban bekas.
