Abstract

Radiator adalah alat yang berfungsi sebagai alat untuk mendinginkan air yang telah menyerap panas dari mesin dengan cara membuang panas air tesebut melalui sirip-sirip pendinginnya. Penelitian bertujuan untukmengetahui laju pembuangan panas dan efektifitas pada radiator dengan beberapa komposisi campuran air dengan radiator coolant.Dalam penelitian ini, dilakukan pengujian perbandingan laju pembuangan panas antara komposisi campuran 90% air dengan 10% radiator coolant, 70% air dengan 30% radiator coolant, 60% air dengan 40% radiator coolant, dan 50% air dengan 50% radiator coolant. Pengambilan data dilakukan dengan mengambil data setiap 5 menit selama 30 menit. Dari penelitian tersebut diambil data antara lain temperatur masuk dan keluar radiator dan volume aliran fluida (Q) yang kemudian dilakukan pengolahan data untuk menentukan laju aliran massa (), panas spesifik fluida (Cp), laju pembuangan radiator (q), dan pengolahan data secara grafik. Hasil penelitian dari beberapa komposisi campuran air dengan radiator coolant menunjukkan bahwa variasi dengan = 1,02 yaitu pada komposisi campuan 70% air dengan 30% radiator coolant yang memiliki nilai laju pembuangan panas yang paling tinggi, hal ini disebabkan nilai Cp pada komposisi ini lebih besar dibandingkan dengan yang lain. sedangkan untuk nilai efektifitas paling tinggi untuk variasi komposisi campuran dimiliki 50% air dengan 50% radiator coolant, hal ini disebabkan (beda suhu rata-rata) berbeda jauh dibandingkan variasi komposisi campuran yang lain.   Kata kunci: Radiator, air, radiator coolant, heat exchanger

Abstract

To obtain maximum engine performance one way to do is to do modification the camshaft . Changes can be made to alter or modify the time to open and close the valve. As already unknow that big power generated by the engine is affected by the amount of residual gases that exit the combustion chamber. The amount of air and fuel mixture entering the combustion gases and regulated by the duration of the opening and closing of the valve.For it was necessary to study the extent to which the effect of the change by the duration of the camshaft to the increased power and torque of the engine, which can then be recovered size is definitely the most appropriate duration to generate great power and torque. Effective power produced at 220 ° camshaft duration variation is at 6000 RPM of 7.7 HP, variations in camshaft duration 227 °, ie at 8.49 HP at 6500 RPM, variations in camshaft duration 233 °, ie at 6500 RPM at 8.77 HP, variations in camshaft duration 239 °, ie at 9.53 HP at 6500 RPM. Average turning moment - resulting in maximum average variation of camshaft duration 220 °, ie at 6000 RPM of 1.37 Nm Variations camshaft duration 227 °, ie at 6000 RPM 1.43 Nm Variations camshaft duration 233 °, ie at 1.47 Nm at 6000 RPM Variations camshaft duration 239 °, ie at 6500 RPM of 1.51 Nm Keywords: effect of variations in the duration of the camshaft, power, torque, and fc (fuel concumtion).

Abstract

In machining  excessive use of cutting fluid can have a negative impact to the  enviroment. An alternative to overcome this problem is by using the minimum quantity lubrication method (MQL). In MQL method the cutting fluid is flowed by compressed  air. This research aim to design and implement an Arduino-based controller for further minimize the use of cutting fluid in MQL system. It was programmed that the pump would only work when the tool temperature beyond 70 oC and vice versa. Observation shows that the controller work accordingly. Other experiments were carried out to check the fluid consumption with Taguchi method. It was proof that applying the controller was able to reduce the fluid consumption.

Abstract

Fish Car Unej (FCU) Mudskip is a car designed with a rural terrain system, especially for fishing transportation. FCU Mudskip uses leaf spring suspension at the rear to support the weight of the vehicle, that is leaning towards the rear. The load of the vehicle is inclined to the rear due to the car carrying system in the form of fish and water. This conveying system can cause leaf spring failure. Therefore, this study aims to determine the value of stress, strain and cycle on leaf springs. Ansys 18.1 software was used to obtain stress, strain, and leaf spring cycle values with a thickness of 7 mm, 10 mm, and 13 mm. The value of stress on leaf springs with thickness 7 is 124,31 x 106 N/m2; thickness 10 mm is 74,92 x 106 N/m2; thickness 13 mm is 48,08 x 106N/m2; the value of strain on leaf springs with a thickness of 7 mm is 0,00075; a thickness of 10 mm is 0,00045; a thickness of 13 mm is 0,00029; Acceptable cycles of leaf springs are 7 mm thick is 69206 cycles, 10 mm is 77833 cycles, and 13 mm thick is 93054 cycles. Leaf springs with a thickness of 13 mm are the most optimal leaf springs because they can receive the most cycles of 93054 cycles, according to the function of leaf springs as vibration dampers.

Abstract

Efficiency and effectiveness are indispensable things in the production process. Accurate use of existing resources and the shorter cycle time of production are of particular concern to optimize the production process. This research aims to implement automation to a conventional blow molding. An advanced attempt was carried out to use the Internet of Things (IoT) to increase its efficiency while maintaining the quality of the products. The use of the nodeMCU microcontroller and the blynk application allows the operator to operate the machine without having to come into or having direct contact with the machine. The performance of automation and IoT were tested by examining the products using Taguchi design using quality criteria of nominal the best. The efficiency of the system was also considered by comparing the cycle production time. S/N ratio of Taguchi analysis showed that the optimum volume of the bottle would be achieved when applying the temperature, injection time, and holding time of 190 oC, 14 minutes, and 5 minutes respectively. The error or deviation is only 0.41%. The application of the IoT system takes 34.45 seconds for a cycle time production, which is 3.76 seconds faster than a conventional system.

Abstract

Since 2006 Indonesia has become the world's largest producer of Crude Palm Oil. Also, palm oil is a strategic commodity both as food (cooking oil). The need for self-cooking oil every day is increasing, causing businessmen who plunge not only to have significant capital but many from SMEs and MSMEs who start a cooking industry in the home industry. In the home industry for cooking oil packaging, the manual method is still used, which is to drain oil from the reservoir to the package through a pipe that is given a tap to open and close. This study studied PLC-based cooking oil filling machines using a timer and timer method to improve efficiency, charging speed, errors as small as possible and to increase production capacity. The test results showed that the cooking oil filling process using the measuring method had an average of 159,478 (g / dt) with an average oil yield of 689.2 grams with an error rate of 0.23%. While the timer method has an average filling speed of 164.336 (g / dt) with an average oil yield of 692.08 grams with an error of 0.336%. The timer method has a faster-charging speed compared to the measuring process, but for the error rate, the purpose is better than the timer method. This is due to the way of using the rotary encoder sensor when charging, so the time required for charging is a little long but with a small error rate. While the timer method uses a timer sensor that is on the PLC to make charging directly into the bottle but has a more significant error compared to using the measuring process. For engine capacity, it is better to use a timer method that produces 5145 liters/day while the gauge method is only 4984 liters/day. whereas for efficiency, it is better the process of measuring is 99.68%, and the timer method is 99.27% Keywords: Timer Method, Measuring Method, Cooking Oil Filling Machine and PLC
