Abstract

The purpose of this study was to determine the shape change characteristics of float sheet glass using heat treatment experiments on its surface. This involved the use of a float glass type with a thickness of 5 mm, a width of 840 mm, and length of 1350 mm as the test specimen and the heat transfer experiments and treatment were conducted through conduction with the heat distribution recorded to be between 34 °C and 600 °C at every 5 minutes within 60 minutes in a heating furnace. The analysis focused on the characteristics of the glass surface exposed to fire with emphasis placed on the temperature during the deflection changes in the entire glass surface, the dimensional changes at the edges of the glass which follow the glass printing pattern, and the changes in temperature on the upper and lower surfaces of the curved glass mold. The results showed the existence of a very clear change in each temperature or conduction heat when the shape of the glass is changed to curve with the ideal shape observed to have changed at a temperature of 482.50 °C. Moreover, dimensional changes were 1.0427 m2 and the variations in the temperature were 107.55 °C and the continuous increase in the heat was to have led to a faster change in the glass shape by 11.2°. This, therefore, means a higher temperature or room temperature affects the firing rate of glass bending and also increases the rate of heat absorption.

Abstract

Pyrolysis has been proven as a method to reduce plastic waste and produce useful products, especially liquid fuels. However, plastic pyrolysis also produces gases and char as by-products which are being investigated for useful products. Therefore, our present study aims to investigate the char characteristics of plastic pyrolysis for further use as briquettes. Seven samples of char by-products from the pyrolysis process of low-density polyethylene (LDPE) plastic at various reaction temperatures and catalyst types were studied. The proximate test is used to determine the properties of char such as moisture content, ash, volatile matter, and fixed carbon while the bomb calorimeter is used to determine the calorific value. Briquettes are formed by mixing 4 grams of char and 0.5-1 gram of binder (1% starch and 90% water). The briquettes were formed into solid cylinders with a diameter of 1.75 cm and formed with a pressure of 10 kg/cm2. Furthermore, the impact resistance index (IRI) was used to test the performance of the briquettes and showed an IRI value between 100 and 200. However, of the seven char samples tested, three of them were impossible to process into briquettes because they melted during the combustion test.

Abstract

Plastic waste is one of the environmental problems that has not been optimally addressed in Bulakan Village. Training in the manufacture of paving blocks from plastic waste through the Community Empowerment Program by Students (PMM) of Muhammadiyah University Purwokerto was carried out as an effort to improve skills and manage waste based on a circular economy. This activity was carried out through several stages, including planning, socialization, the handover of hot mixer equipment, the provision of materials, and the practical production of paving blocks. The results of the activity showed an increase in the knowledge and skills of the participants based on a comparison of pre-test and post-test results, as well as the participants' success in independently practicing the production process. Additionally, this program has a positive impact on partners and the community by transforming plastic waste into useful products and creating new business opportunities for the community. This training demonstrates that plastic waste can serve as an alternative building material while supporting waste reduction at the village level.

Abstract

Pemanfaatan energi surya sebagai sumber energi alternatif dalam sektor kelistrikan terus mengalami perkembangan pesat seiring meningkatnya kesadaran masyarakat. Namun demikian, panel surya Photovoltaic masih menghadapi tantangan signifikan dalam hal efektivitas, efisiensi konversi energi, dan performa pendinginan yang kurang optimal. Kondisi ini berdampak langsung pada penurunan daya keluaran dan efisiensi kerja panel, sehingga membatasi potensi maksimal teknologi Photovoltaic. Salah satu aspek krusial dalam menjaga kinerja panel adalah sistem pendinginan yang mampu menstabilkan suhu kerja panel saat beroperasi. Penelitian ini bertujuan untuk mengevaluasi pengaruh metode pendinginan terhadap efektivitas, efisiensi, serta karakteristik termal dan hidrolik panel surya fotovoltaik melalui pendekatan eksperimental dan numerik. Objek penelitian menggunakan panel surya berbasis material polikristalin silikon berukuran 76 cm × 67 cm dengan kapasitas daya maksimum 100 Watt. Kegiatan ekperimen dilakukan dengan dua skema pendinginan pasif yaitu konveksi bebas dan penggunaan material pengubah fasa (PCM) berupa minyak kelapa dan lemak hewan. Hasil penelitian menunjukan efisiensi pendinginan konveksi bebas sebesar 23,68%, sedangkan pendinginan PCM minyak kelapa 22,08% dan lemak hewan 29,44%. Panel surya dengan menggunakan PCM lemak hewan didapatkan nilai output power sebesar 92,17 Watt, dengan penurunan temperatur permukaan sebesar 5-9℃. Aplikasi PCM ini terbukti meningkatkan efisiensi dan efektivas kinerja photovoltaik dalam menghasilkan energi listrik.

Abstract

Automated Guided Vehicles (AGVs) are a smart transportation solution that is increasingly being used in industry. The stability and strength of the chassis are critical factors in ensuring AGV performance when carrying loads. This study examines the effects of load variations and material types on the structural performance of AGV chassis through an experimental approach and numerical simulation based on Finite Element Analysis (FEA). The materials used were ASTM A36 and ASTM A500, with loads of 5 kg, 10 kg, and 15 kg. A chassis design with dimensions of 400 × 300 × 80 mm was modeled and analyzed using Computational Fluid Dynamics (CFD) software. Validation was performed through experimental testing using a dial indicator. The results show that at a 15 kg load, ASTM A500 experienced a maximum stress of 60.15 MPa and a deflection of 0.00078 m, lower than ASTM A36, which reached 68.06 MPa and a deflection of 0.00089 m. The difference between the simulation and experimental results was well below 10%. Similarly, regarding the safety factor, ASTM A500 has a value of 2.7145 at maximum load, indicating that this material has a higher safety margin compared to ASTM A36. Based on these results, ASTM A500 is considered more efficient and stable, and is more recommended for AGV chassis applications. This study highlights the importance of integrating numerical and experimental methods to produce optimal structural designs.
