Abstract

Pengaplikasian teknologi dapat mempermudah manusia dalam kehidupan sehari-hari. Salah satu tekonologi ini adalah RFID. Pada pembuatan chip RFID, timbul masalah pada proses pick and place yaitu terdapat beberapa variabel set up mesin yang kurang optimal, kendala tersebut membuat mesin kurang efisien dalam waktu dan kualitas, sehingga dilakukan optimalisasi variabel-variabel tersebut. Proses optimalisasi pada penelitian ini tidak hanya mempertimbangkan cycle time yang minimum tetapi juga kualitas produk yang dihasilkan. Oleh karena itu pada tahap awal percobaan dicari selang nilai dari variabel-variabel yang akan dioptimalisasi. Pada selang ini produk yang dihasilkan masih masuk ke dalam spesifikasi kualitas yang telah ditentukan. Langkah selanjutnya adalah proses optimalisasi cycle time menggunakan Design of Experiment dengan metode RSM. Tujuannya meminimalisasikan cycle time sehingga produk dapat lebih banyak diproduksi tanpa mengorbankan kualitas. Hasil dari metoda ini adalah cycle time selama 3.188 detik dari yang sebelumnya 4.9 detik. Diketahui pada satu leadframe terdapat 36 chip. Sehingga total waktu pick and place menurun menjadi 1.91 menit per leadframe (3.188x 36). Untuk perhitungan waktu die attach ditambah pick and place per leadframe adalah = 1.91 menit + 1.30 menit (epoxy application) + 1 menit (handling) + 0.35 menit (inspection) = 4.56 menit. Dari hasil perhitungan ini akan diperoleh UPH 13 leadframe, meningkat sebanyak 2 leadframe dari sebelumnya.

Abstract

Analog sensors are devices used in the process industry. These sensors can be used to measure the pressure, flow, temperature, and level of a fluid in a tank. A sensor is an important part of a feedback control system that is commonly used in the process industry. In this research, an analog sensor was used to measure water pressure on a couple tank kit, which was SKU SEN0257. This pressure was converted to the depth of the water in the tank. A problem occurred when the dimension of the tank was small, then the depth change of water could not be read by a controller that connected to the sensor. Therefore, a prototype of instrumentation amplifier using IC OP027 was designed. This amplifier was used to increase the output voltage from the sensor so that it could be read by controller. The circuit that has been designed, managed to produce voltage around the desirable value 0-5V. Problem that arise from this research is the fluctuation in the amplified voltage value that need further improvement on the circuit design.

Abstract

Process control is one of the automation techniques that has been commonly used to control pressure, temperature, flow and fluid level in industrial factories, which aims to maximize production, maintain product quality levels, safety in production, and create a more economical production process. Based on these needs and situation Politeknik Negeri Batam begin to developing laboratorial module for the students. One of these modules is STEM Pressure Measurement and Control Plant with developed by adding a data acquisition system based on PLC CP1H and CX Supervisor application as data presentation element. The results of this study indicate that the application of the CX Supervisor and PLC CP1H has supported the development of learning, especially in the practice of process measurement and control. From the test results it can be seen that the three pressure transmitters used have linear characteristics according to the specifications of the device. From the test results of the proposed data acquisition system, the measurement results show a value that is close to the actual value with a deviation value of -0.1–0.17 and standard deviations of 0.088, 0.075, and 0.107 and standard errors of 0.024, 0.021, and 0.030, respectively for pressure transmitter with capacitance, piezoresistive, and extensimeter types
