Abstract

This research is about making a prototype of four blades savonius wind turbine as a learning media for Energy Conversion in the Mechanical Engineering Department, Bangka Belitung University. The making of this learning media is due to the limitations of student practicum facilities to support the continuity of practical and conducive lectures. The prototype was made with small dimensions, namely a frame of 0.75m x 1.5m and a turbine blade diameter of 0.15x0.3m. A fan-assisted the study as a wind energy generator. Wind speed variations carried out at three rates following the wind speed generated by the fan. The rate of wind speed measured using an anemometer and the rotation using a tachometer. The current and voltage are measured using a multitester. Turbine blades are varied with 4 blades with three-blade profile models, namely U, L, and S. Research, shows that wind speed influences turbine performance. The higher the wind speed, the higher the rotor's rotation, and so the resulting power. The best profile is obtained from the L model, which reaches 177.63 rpm with 6.35 watts of power.

Abstract

Penelitian ini tentang pemanfaatan kulit pisang kepok menjadi bubuk minuman kopi. Kulit pisang ini umumnya dihaluskan dengan menggunakan blender, namun kelemahannya adalah kapasitas produksinya lebih rendah, sehingga untuk memproduksi dalam jumlah banyak harus dilakukan proses berulang. Berdasarkan hal tersebut, maka dibuatlah sebuah mesin penghalus kulit pisang hingga menjadi bubuk dengan tingkat kehalusan bubuk kopi pada umumnya. Kulit pisang yang digunakan yaitu kulit pisang kepok matang. Proses penghalusan kulit pisang menggunakan mesin dengan menggunakan motor listrik sebesar ½ HP, dengan putaran pada poros penghalus yaitu 1050 rpm. Hasil pengujian dengan bahan uji dengan massa 500 gram yaitu dalam waktu 1 menit menghasilkan 215 gram, waktu 2 menit menghasilkan 225,7 gram, waktu 3 menit menghasilkan 250,7 gram.

Abstract

This research is a design of a potato cutting machine. The ultimate goal of making the machine is the production of potato cubes. In planning the machine will be processed to produce stick-shaped potato pieces. The machine design is made with dimensions of 660 mm x 800 mm x 710 mm using an electric motor ½ Hp. The system of lowering the rotation uses a pully and belt 1: 2 and continued with a gearbox with a ratio of 1:40, the way the engine works is to rotate the crankshaft to move the piston / potato suppressor with a rotation of 17.5 Rpm. The study was conducted 3 times with 1000 grams of potatoes with an average yield of 702 grams of good cut, 27 grams unsuccessful, 271 grams behind. The production capacity of this stick-shaped potato cutting machine is capable of cutting as much as 20.29 kg / hour with a machine production efficiency of 70.02%.

Abstract

ABSTRAK Proses pengupasan kulit bawang putih dapat dilakukan dengan cara manual atau menggunakan mesin. Pada mesin pengupas kulit bawang putih terdahulu menggunakan motor listrik 0,5 hp, dimensi 750 mm x 500 mm x 750 mm, menggunakan pulley dan belt untuk mereduksi putaran menjadi 100 rpm. Hasil penelitian terdahulu diperoleh kapasitas produksi mesin 2,06 kg/jam dan efisiensi produksi mesin 86%. Kekurangan mesin terdahulu antara lain : dimensi tabung pengupas yang kecil hanya efektif untuk 1000 gram, sering terjadi slip pada pulley, kecepatan putaran pada poros pengupas tidak dapat diubah-ubah. Modifikasi dilakukan pada bagian-bagian mesin antara lain: memperbesar dimensi tabung pengupas, memvariasikan tabung pengupas, menggunakan gearbox untuk mentransimisi putaran, menggunakan daya 0,25 hp, dan menambah dimmer sebagai pengontrol putaran. Mesin yang dimodifikasi berdimensi 970 mm x 500 mm x 800 mm dan kecepatan putaran tabung pengupas 120 rpm. Hasil penelitian menunjukkan bahwa, kapasitas produksi mesin untuk tipe tabung pengupas tanpa pengaduk 2,88 kg/jam dengan efisiensi produksi mesin adalah 58,6% . Kapasitas produksi mesin untuk tipe tabung dengan karet pengaduk adalah 1,2198 kg/jam, efisiensi produksi mesinnya adalah 47%. ABSTRACT The process of peeling garlic skin can be done manually or using a machine. In the previous garlic peeler machine using a 0.5 hp electric motor, dimensions of 750 mm x 500 mm x 750 mm, using a pulley and belt to reduce rotation to 100 rpm. The results of previous studies obtained a machine production capacity of 2.06 kg/hour and a machine production efficiency of 86%. Disadvantages of previous machines include: the dimensions of the peeler tube are small, only effective for 1000 grams, slips occur frequently on the pulley, the rotational speed of the peeler shaft cannot be changed. Modifications were made to the engine parts, including: increasing the dimensions of the stripper tube, varying the stripper tube, using a gearbox to transmit rotation, using 0.25 hp of power, and adding a dimmer to control the rotation. The modified engine has dimensions of 970 mm x 500 mm x 800 mm and the peeler tube rotation speed is 120 rpm. The results showed that the machine's production capacity for the peeler tube type without agitator was 2.88 kg/hour with the machine's production efficiency of 58.6%. The machine's production capacity for tube type with rubber stirrer is 1.2198 kg/hour, the machine's production efficiency is 47%.

Abstract

The Energy Efficient Car Competition (KMHE) is an annual competition organized by the national achievement center (puspernas), Bangka Belitung University regularly participates in the KMHE competition starting from 2015 to 2022, but UBB's KMHE car has not been able to compete to win the category of prototype gasoline, car KMHE has many shortcomings, especially fuel consumption which is still relatively high, namely 130 km / liter, one method of saving fuel consumption is by adjusting the length of time the injector opens (fuel correction). This study aims to determine the effect of the fuel correction value with a variation of 0 , -11, -23, and -27 on fuel consumption. The Electronic Control Unit (ECU) used is a programmable type ECU, the test is carried out at various engine speeds (RPM 1000, 2000, 3000, 4000 and 5000) with a 5 minute test time. The results showed that the most efficient data on fuel consumption was at fuel correction -27 at 1000 RPM, namely 4 ml and the highest fuel consumption was at correction 0 at 5000 rpm, which was 67 ml.
