Abstract

The thermoelectric generator (TEG) has long been used to produce electrical energy where when a temperature difference occurs between two different semiconductor materials, this thermoelectric element will produce a voltage difference and flow an electric current. This principle is known as the 'Seebeck effect'. This research was conducted to determine the electrical energy potential of the TEG module as an alternative energy source by utilizing chimney heat from an incinerator. The test was carried out with a variation of 1, 2 and 3 m chimney height with treatment without compaction and compaction of waste. The test results show that with 12 TEG modules arranged in series electricity can produce an output voltage with a maximum temperature difference of each ΔV 3,31 Volt ; ΔT 15,0 °C (1 m), ΔV 3,92 Volt; ΔT 17,8 °C (2 m), ΔV 4,84 Volt ; ΔT 22,0 °C (3 m) while the compaction of each value ΔV 6,34 Volt ; ΔT 29,2 °C (1 m), ΔV 7,69 Volt ; ΔT 35,2 °C (2 m), ΔV 9,09 Volt ; ΔT 41,5 °C (3 m). The potential power that can be produced is as big as 3,22 W (1 m); 4,56 W (2 m); 6,88 W (3 m) while the compaction of waste is equal to each value 11,80 W (1 m); 17,36 W (2 m); 24,25 W (3 m). The addition of chimney height variation resulted in an increase in the hot side temperature (Th), cold side (Tc) and temperature difference (dT) so that heat energy and power energy increased.

Abstract

This research was conducted to determine the character of the TEG module as a source of electrical energy in utilizing heat in the chimney wall of an egg rack drying machine that uses rice husk as engine furnace fuel. The test is carried out by utilizing heat on 2 pieces of chimney (upper chimney and lower chimney) separated by a Heat Exchanger (HE) with a furnace blower speed of 2600 rpm and environmental blower speed of 2800 rpm with the amount of thermoelectric used as many as 44 units. The results show that the TEG module in the upper chimney obtained temperature difference (∆T), voltage difference (∆V) and power (P) respectively ∆T 38.75 ° C; ∆V 3.68 Volts; P 0.796 Watt and for the lower chimney respectively ∆T 73.25 ° C; ∆V 12.26 Volts; P 2.446 Watt.

Abstract

Salah satu penyebab terjadinya banjir adalah faktor sampah yang banyak tersebar di kanal. Salah satu cara mengatasinya adalah dengan membuat robot pengangkut sampah pada kanal sempit. Adapun tujuan penelitian ini adalah merancang sebuah model robot pengangkut sampah pada kanal dan mampu membuat program arduino dalam mengopersikan robot tersebut. Bagian-bagian robot ini adalah rumah robot, rangka pengangkut sampah, pengangkut sampah, motor penggerak sistem, roda pengerak, arduino uno dan perangkatnya serta aki. Prinsip kerja robot ini adalah program memberi printah kerja pada sistem atau motor penggerak untuk menggerakkan rangka pengangkut sampah bergerak turun ke kanal untuk menemukan air. Di saat sensor air telah menyentuh air maka sensor akan mengirim ke program agar memberhentikan motor penggerak rangka pengangkut sampah. Bersamaan dengan itu, program memerintahkan/mengirim sinyal ke motor penggerak pengangkut sampah (jaring-jaring dan bilah pipa) agar berputar, sehingga bergerak menyaring sampah yang ada. Pada penelitian ini robot pengangkut mampu mengangkat sampah 5 kg sehingga diproleh torsi mesin 7,5 kg.cm dan Daya sebesar 117,75 Watt. Sedangkan menurut perhitungan mesin robot ini mampu mengangkat sampah sebesar 66,7 kg memiliki torsi sebesar 100 kg.cm dan daya sebesar 14401,7 watt.
