Penggunaan sensor yang mampu untuk mengidentifikasi jenis gas sangat dibutuhkan di industri. Salah satunya adalah sensor Quartz Crystal Microbalance (QCM) yang dapat menghasilkan frekuensi resonansi konstan. Pada umumnya sensor QCM masih menggunakan frekuensi dasar resonansi sehingga tingkat sensitivitas masih rendah. Dengan mengambil frekuensi harmonisa dari frekuensi resonansi dasar maka dapat meningkatkan sensitivitas dan selektivitas. Pada penelitian ini dihasilkan rangkaian osilator frekuensi harmonisa 3fo yang dapat bekerja dengan baik saat identifikasi jenis gas. Sensitivitas sensor QCM yang menggunakan frekuensi harmonisa 3fo dievaluasi dengan memantau perubahan frekuensi pada konsentrasi gas yang berbeda, seperti alkohol, 2-propanol, dan kloroform. Deret sensor yang dilapisi material kimia yang berbeda, menghasilkan pola output dari respon frekuensi yang berbeda-beda. Pengukuran juga dilakukan terhadap perubahan kelembaban sebesar 27-74% RH dan perubahan konsentrasi 1-4 ml gas yang diujikan. Hasil percobaan menunjukkan bahwa sensor QCM berfrekuensi harmonisa 3fo menghasilkan sensitivitas dan selektivitas yang lebih baik dari pada frekuensi dasar sensor. Untuk frekuensi 5MHz sensor QCM dalam pengenalan jenis gas memperoleh tingkat keberhasilan sebesar 73.33%, sedangkan untuk frekuensi harmonisa 3fo memperoleh tingkat keberhasilan sebesar 86.67%.

Sensors that are able to identify the type of gas are needed in the industry. One of them is a Quartz Crystal Microbalance (QCM) sensor which can produce a constant resonance frequency. In this study, we intend to determine the sensitivity of the QCM gas sensors which are coated with different polymers. QCM gas Covered with polymer sensor based QCM aim to increase the sensors ability to absorb molecules on the surface of the QCM sensor. The sensor array coated with different polymer materials will produce different frequency response output patterns for each type of gas identified. The test results showed that the QCM sensor coated with OV 17 polymer material was more sensitive by producing sensitivity of 8.4 Hz /ml alcohol, 9.96 Hz /ml 2-propanol, 35.88 Hz /ml acetone, 39.64 Hz /ml benzene.

The development of Hydroulic Regenerative Shock Absorber starts with presenting theories that work, and simulates them with numerical computing software to becompare with conventional shock absorber systems. The generation energy of the regenerative suspension system is only effective for high amplitude. When the amplitude is low, the generation energy will decrease as a result of bidirectional rotation and inertial losses. The greater the generator rotation, the higher current, and power generation. In the HMERSA fluid flow simulation 1 input and single output using the Fluid SIM software. the input given is 3 Hz on the hydraulic cylinder that is on the 4-wheel vehicle. The simulation was done by changing the hydraulic circuit and adding a check valve mechanism so that the rotation of the hydraulic motor becomes unidirectional. In this simulation there is no generator component because in the Fluidsim software does not provide these components in the simulation. The simulation using the Fluidsim software is intended to find out whether the hydraulic circuit that has been designed runs well marked by the rotation of the one-way hydraulic motor rotation. The design design of HMERSA with 1 input 1 output can run well marked from the rotation of the hydraulic motor into one direction when the conditions are expansion or compression. The torque value that occurs during an expansion condition is 1.1 Nm, while for the torque value that occurs when the compression condition is 1.6 Nm. The power generated from the hydraulic motor when the expansion condition is 1.6 Watt. Whereas when the compression condition of the power of the hydraulic motor that can be produced is 4 Watt.

In the dam there is a sluice gate that functions to hold water and regulate the volume of water in the dam. So far, the dam gate has been controlled manually by humans so that the water volume does not exceed the limit. The manual system requires humans to always monitor the water level of the dam. The purpose of this research is to make a prototype system for opening and closing the floodgates of the dam automatically to facilitate humans in the process of opening and closing the bars. This prototype uses an Omron PLC as the main controller, two level sensors to provide information on the water volume level, a red indicator light and a buzzer as an indicator that the water has crossed the limit, a green indicator light as an indicator of the water has dropped, and a DC motor as a dam door driver. This prototype is equipped with a Human Machine Interface (HMI) as a display on a laptop screen. The results of this prototype test, the dam door can be controlled according to water level conditions. The dam door will open automatically when the water level has reached the maximum limit, and the dam door will close again when the lower level sensor is detected. The process that occurs can be displayed on the laptop screen with an HMI simulation.
