Abstract

Indonesia is one of the countries that has the third-largest number of volcanoes in the world. Several volcanoes are still active today. This places Indonesia prone to disasters from the volcano. One of the volcanic activities is characterized by the release of poisonous gases such as CO2. At a certain threshold, this poisonous gas can kill living things. This research has designed a gas-producing engine as a replica of volcanic gas. This machine is very supportive of the development of volcanic gas research on a laboratory scale because it has the advantage of being lighter, simpler construction, cheaper and portable machine construction process. The gas produced by the machine is tested using the Dragger X-am 7000. , CO2, H2S, SO2, and CO. The results were obtained for 60 seconds of starting the engine, namely CH4 2.0% LEL, CO2 1.6% Vol, H2S 4.3 ppm, SO2 1.0 ppm, and CO 271 ppm.

Abstract

The level of oxygen saturation in the blood is important to know the health condition of the body. If the human body lacks or excess oxygen, it will cause illness and other bodily system work disorders. One of the tools to detect the oxygen saturation level is the Pulse oximeter. Previous research has successfully designed a Pulse oximeter based on Arduino. The pulse oximeter produces a photoplethysmograph (PPG) signal that corresponds to the standard PPG signals in 20 test samples. PPG signals can be processed to provide information on oxygen saturation (SpO2) levels in the blood. In this research, validation of the Pulse oximeter is compared with a commercial pulse oximeter, the digital oximeter JZK-301. The results obtained from this validation are the smallest deviation errors are 4.83% while the largest errata is 22.51%. The greatest accuracy of 95.17%, of respondents number 16 and the smallest accuracy is 77, 49%, that is the number of respondents 12. The average deviation of 20 data is 12.82% with the resulting accuracy is 87, 18%. This indicates that the self-designed pulse oximeter has good efficiency and can be developed further

Abstract

Rocket technology with water propellant is becoming more popular and as an alternative to be applied to education and recreation, such as industry and the military. The use of water rockets as an easy, safe, and inexpensive means of measuring physical parameters at heights above the earth's surface is being intensively carried out. One alternative solution is aerodynamic water rocket technology equipped with a telemetry system. The rocket used for the test launch is made from untested carbon fiber. Flight test settings by filling 1/3 of the tube volume with water and a pressure of 200 psi. The results of the water rocket launch show a maximum height of 265 feet or 80.77 m. Changes in acceleration on the x-axis, y-axis, and z-axis indicate the normal motion of the flying rocket. Analysis of stability and control of the rocket is seen in the measurement of the tilt angle of roll, pitch, and yaw. When the rocket moves or tilts, the angle measured corresponds to the tilt. In the roll condition, the rocket moving from launch to landing shows the rocket's rotational motion at an angle of approximately 20o. The potential of water rockets that can still be developed, needs to be increased the reliability of water rockets both in terms of utilization and research.

Abstract

Water is a vital human need that must be met for human survival and carrying out daily activities. However, the condition of natural resources in each region is different, not all regions have sufficient water availability. One of them is in Serut, Gunungkidul which is an area with hilly geography. During the dry season, clean water sources in Serut District become scarce and very limited. Therefore, the Serut District Government cooperates with the Community Self-Help Group (KKM Tirta Abadi Jaya) to drill deep wells to distribute water to residents. However, along the way, the operational costs are very large, especially for water pump electric pulses. In addition, the geographical condition of Serut which is hilly and has many trees causes frequent power outages, especially in extreme weather. This affects the resistance of the water pump because it is often on and off. The power outage can also stop the distribution of water to residents. This community service provides a solution to these problems, namely the installation of solar electricity generation. With this solar electricity generation, it can reduce the operational costs of electric pulses. In addition, using solar electricity generation can increase the durability of the tool because there is no on-off. Residents also still have their water needs met even though there is a power outage because the electricity needs for water pumps are supplied from solar electricity generation.

Abstract

Indonesia’s geographical conditions are one of the causes of land movement. This land movement can occur due to the movement of rock masses, soil, or debris material making up the slopes. The stability of a slope is influenced by several parameters such as material, soil strength, slope angle, climate, vegetation, and time. In Indonesia, land movement disasters are placed the third rank of natural disasters that occurred throughout 2021. Thus, the development of a land movement detection system is very important for monitoring land movement disasters. In this research, a land movement detection device was developed using the ADXL 335 accelerometer sensor and fiber optic. For data acquisition, Arduino Uno, LEDs, and photodetectors were used. Arduino Uno was used to convert analog signals to digital. In addition, LEDs were used as light sources, and photodetectors were used as a receiver. Changes in the output voltage due to macrobending loss are obtained when the curvature changes due to the pendulum system. The results of the study show that the average acceleration values on the x, y, and z axes of the accelerometer sensor are 0.118 g, 0.925 g, and -2.494 g. The maximum land displacement movement that can be represented by fiber optic is 4 cm. Further, the combination use of accelerometer sensors and fiber optic can show the magnitude of the force that causes displacement, the direction of land displacement, and the magnitude of the land displacement that occurs.
