Abstract

Baja ST 60 termasuk baja karbon sedang yang merupakan bahan yang mudah dibentuk. Baja ini mempunyai kandungan karbon 0,3% - 6%. Penggunaan pada industri permesinan bisa mengakibatkan struktur logam terkena gaya eksternal seperti tegangan gesek yang mengakibatkan perubahan bentuk. Pada penelitian baja ST 60 ini mempunyai tujuan untuk mengetahui sifat kekerasan dari baja ST 60 tersebut. Dalam penelitian ini diawali dengan proses preparasi material menjadi spesimen uji, kemudian dilakukan perlakuan panas (heat treatment) pada suhu yang sudah ditentukan yaitu 850 °C dengan variasi waktu tahan (holding time) 10, 15, 20, 25 dan 30 menit pada tungku pemanas (furnace) dan kemudian di lakukan pendinginan secara cepat (quenching) pada oli SAE 50. Setelah di quenching, spesimen uji tersebut dilakukan pengujian kekerasan. Dari pengujian didapatkan hasil bahwa sifat kekerasan baja ST 60 setelah dilakukan perlakuam panas terjadi peningkatan, yaitu dengan nilai kekerasan maksimum pada holding time 30 menit sebesar 26,50 HRC dan minimum pada holding time 10 menit sebesar 32,20 HRC. Sedangkan sebelum perlakuan panas kekerasnnya 12,48 HRC. Meningkatnya sifat kekerasan ini dikarenakan holding time yang lama akan mempengaruhi butiran karbon yang menyebar ke permukaan baja ST 60.

Abstract

Bercak merupakan cacat pada permukaan plastik hasil proses injection molding. Penyebabnya adalah adanya kandungan air yang terperangkap. Penelitian ini bertujuan menentukan berapa lama durasi  waktu pengeringan untuk menghilangkan bercak. Caranya dengan menghitung waktu sejak pemanas hopper dinyalakan sampai material plastik digunakan. Sebab satuan waktu merupakan parameter paling mudah dikontrol  oleh pekerja (operator) mesin injeksi. Penelitian dengan cara melakukan proses cetak plastik menggunakan mesin injeksi pada material acrylonitrile butadiene styrene (ABS). Cacat bercak diamati pada permukaan produk hasil cetak. Pengamatan dilakukan secara visual langsung saat produk keluar dari cetakan. Produk yang baik adalah permukaan halus tanpa bercak. Pengeringan terbaik diperoleh pada suhu 84֯C selama 4 jam. Pengeringan kurang dari 4 jam pada produk masih timbul bercak, pengeringan diatas 4 jam merubah warna karena pigment terbakar efek dari terlalu lama dipanaskan.

Abstract

In response to the problem of plastic waste, this study investigates the conversion of PET waste plastics into Pyrolysis Plastic Oil (PPO) as an environmentally sustainable alternative energy source, aiming to tackle the pressing issue of plastic waste accumulation. Accordingly, the research comprehensively evaluates the physicochemical properties of PPO, examines its impact on engine performance, and determines the optimal concentrations for blending with gasoline. The investigation uncovers the potential of PPO through precise material preparation involving PET plastic waste pyrolysis, employing meticulous testing and analysis for comprehensive insights. Engine testing, conducted on a 125 cc, 4-stroke motorized vehicle, scrutinizes power, torque, and exhaust emissions under various PPO and gasoline blends. The findings reveal distinctive relationships between PPO ratios and engine behavior, emphasizing the need for nuanced fuel blending. The examination extends to fuel consumption and specific fuel consumption (SFC) testing, highlighting PPO's superior SFC. Exhaust emission testing demonstrates reduced emissions with heightened PPO concentration, showcasing its positive environmental impact. The results contribute valuable insights into PPO's viability as an alternative fuel source and its potential role in mitigating plastic waste. A comparative analysis with existing literature enriches our understanding of the field, emphasizing the need for careful consideration in fuel formulation. While PPO may not achieve performance parity with conventional gasoline, its environmental benefits and efficient waste utilization underscore its significance for a sustainable future. Further research is encouraged to optimize PPO properties and blending ratios, paving the way for an eco-friendlier energy landscape.

Abstract

Piezoelectric is one of the generators of electrical energy when the material is deflected due to pressure. Research has been done on the potential of the fins on the electric voltage produced by piezoelectric. The research method used is to observe the piezoelectric vibrating due to the flow of air passing through the bluff body resulting in a deflection of the fins to strike the piezoelectric and measuring the electric voltage. Changes in the speed of fins installed with piezoelectric dimensions, namely fin one length 12 cm and width 10 cm, fin two length 12 cm width 10 cm and tip width 12 cm, fin three length 12 cm, width 10 cm and tip width 14 cm. The research was conducted in a mini wind tunnel with wind speeds of 5 m/s, 7 m/s, and 9 m/s with a piezoelectric distance to the rhombus bluff body is 80 mm. The results obtained are fin 1 with a speed of 9 m/s produces an electric voltage of 5.15 volts, fin 3 with a speed of 9 m/s produces an electric voltage of 5.46 volts, and fin 4 with a wind speed of 9 m/s has the highest voltage value, namely 5.58 volts. The airflow as it passes through the end of the bluff body section causes the fin to move up and down. The greater the turbulence that occurs, the greater the air hitting the piezoelectric surface so that the value of the electric voltage becomes high.

Abstract

Currently, buildings are responsible for 32% of the world’s energy consumption, with the most massive energy-consuming device in facilities being the refrigeration system. Photovoltaic is an alternative source of energy without causing environmental damage. Solar Refrigeration is an attractive solution because when there is much solar radiation, peak thermal energy is generated, and a lot of cooling capacity is needed. In this research, the amount of PV modules used as the LiBr-H2O Absorption Refrigeration System’s primary energy source is investigated. PV modules have a dual function, namely as a producer of electric power and producing thermal waste, both of which can be used as energy sources to drive this refrigeration system. In this thermal waste, two thermal sources, namely thermal convection and thermal radiation, accumulate to activate heat exchange at the LiBr-H2O absorption refrigeration system’s generator side. For electrical power from the PV module, it is used to run the air heater to increase the temperature until it reaches the optimum point for hot water supply between 65 to 70 oC. The results are that at least 100 modules of 100Wp Monocrystalline PV Module are needed to drive the LiBr-H2O absorption refrigeration system. Still, it is limited to 15.00, after which the energy source is switched back to electricity from PLN because, after 15.00, many PV modules are required and takes up a large enough space.

Abstract

The choice of fuel (fuel oil) whose price is higher needs a solution, especially for conventional foundry entrepreneurs. We need alternative energy that is cheap and easy to get. Wood pellets are an attempt to replace fuel with cheap fuel. As with previous studies, the main objective of this study was to measure the energy potential of the smelting furnace flue gas. The analysis results show that 365,413.3 kJ of heat energy is wasted from the total point required for smelting. The flames sometimes coming out of the furnace flue gas channel indicate that some heat energy is smashed into the free air. The exhaust gas temperature is measured at 500-550⁰C, and you can see flashes of fire coming out frequently. This indicates that there is energy potential for the working process of the pyrolysis reactor; apart from that, the moments of fire that often appear indicate an excess of the combustion process in the furnace. This study's results may differ from other smelting furnace constructions and conditions.
