Abstract

This study utilizes Landsat 8 satellite imagery using image processing techniques ranging from radiometric correction, image band merging, and image cutting to obtain the area to be analyzed, namely Malang City. To obtain green open space data in the research area, the NDVI method was chosen as the method. The vegetation density is divided into several classes. The image processing results are compared with the results of field tests using google street view to determine whether the results of the analysis are accurate. The results of the analysis obtained were then made a Decision Support System with the SAW method. This study's output was the creation of an android application containing information systems about green open space in Malang City and recommendations for actions for the benefit of green open space management in Malang City. The system created based on the 2020 image analysis resulted in adding green open space needed in 3 sub-districts, namely Klojen District, Sukun District, and Blimbing District. Meanwhile, the data's accuracy in this study amounted to 86% of the overall data analyzed. In 2016 the total area of ??green open space was 17.81%, in 2017, the area of ??green open space was 15.57%, in 2018, there was a significant increase in the area of ??green open space by 27.92%, in 2019 the area of ??green open space was 17.43%, and in 2020, the area of ??green open space is 17.18% of the total area of ??Malang City.

The results of TV service output using the Hybrid Fiber Coaxial system obtained a signal quality of 74% with a total of 49 channels. The attenuation with input 1 parabolic antenna receiver decoder using 200 cm fiber optic obtained a loss of 1.79 dB and at length of 2 km the loss is 8.91 dB. Whereas with the input of 2 decoder, a parabolic antenna receiver using 200 cm fiber optic, the value of losses is 1.93 dB and at 2 km the loss is 9.83 dB. The average deviation of RGB errors in the largest television image output results is Green by 0.226% and the lowest error deviation is Red at 0.148%. The effect of audio and video output before adding fiber optic devices is obtained, the audio output voltage value is 1.792 V and the video output voltage value is 2.591 V. After adding the fiber optic device the value of the output voltage with 1 television output and 1 decoder receiver at a length of 200 cm audio is 1.144 V and video is 1.167 V while at a length of 2 km the audio is 0.834 V and the video is 1.005 V.

Abstract

The rapid development of technology increases the competitive power of the business world which is getting bigger. This technology has information and communication systems that are easily accessible by the internet. In a restaurant / shop has different ordering systems. Drive thru is a service that is considered a modern system, consumers can easily order food or drinks even though they are still in the vehicle and do not need to enter the store. In the drive thru ordering system, consumers come to the intended shop and can order food from the vehicle without the need to enter the restaurant, where the order is ordered directly in front of the microphone outlet which is connected to the cashier specifically for drive thru consumers and if so, consumers can continue. to the cashier to make payments and take orders. In this study, a food ordering system is proposed for the drive thru store, by making an application and web admin where consumers can place orders quickly, and there is also Qrcode which functions as a sign of user purchases and Epay's balance which simplifies the payment process. Web functions as admin data. The test results can be concluded that the Qrcode detection on Qrcode scanner has an average reading accuracy at a distance of 2.98cm, in the Qos test which is carried out with different networks, the result is that the Telkomsel provider gets the smallest delay with a value of 0.121766.

Abstract

Indonesia has a famous sweet potato called Ubi Cilembu that has a chewy and attractive meat structure. The advantages of this sweet potato, if baked in an oven, will produce a sweet honey flavor. Cilembu Sweet Potato that does not taste honey when eaten will reduce the delicacy because during the roasting process using an oven, there is no temperature control system that causes not toasted properly. Since reversing Cilembu yams is still done manually which can be endangering workers if exposed to a hot part of the oven. Because of this, the researcher will make it easier for users to work on the cilembu sweet potato roasting process more effectively than an oven control system is made. The implementation system is done by entering the temperature setpoint value and the timer via the remote displayed on the LCD, then the data is sent using a wireless module when the oven's half-timer time will rotate automatically by using the servo metal gear. The results are carried out by using a remote temperature control in the oven by entering the temperature setpoint value and the timer via the remote displayed on the LCD, then the data is sent using the wireless module when the furnace timer half time in the oven will rotate automatically using a metal servo gear. The system performance is designed to work within 2 hours with a weight of 1 kg of cilembu sweet potato using a temperature of 100.50 ° C.

Abstract

In this study, the application can be used so that consumers can find out the fat content and acidity in Barco oil, fish dorang, and bulk oil which has an android monitoring system in real-time. This research uses Arduino UNO and Node MCU as the microcontroller. Arduino Uno will later be assembled together with water pH modules, ultrasonic HC-SR04, and capacitive soil. The pH module functions to measure the water and fat content in palm oil. An ultrasonic module that functions to measure the volume of the oil measurement container. The capacitive module is used to determine the density of quality in saturated oil. The test results can be concluded that the pH sensor can detect levels of fat and acidity in palm oil has a value of about 5 to 11. Ultrasonic sensors on the volume of oil samples of Barco and fish dorang have a significantly increased grapH, while the bulk oil sample has a very high grapH which causes acidity oil. This study has the highest delay of 1.303525ms and the lowest delay of 0.628276ms. With an average value of delay obtained of 1.189657 ms.

Abstract

The increase in temperature on optical fiber results in an increase in the refractive index and Numerical Aperture, resulting in spread and absorption losses in the optical fiber. So it is considered necessary to discuss the effect of temperature changes on wave length in axially connected Singlemode-Multimode fiber optic media. Optical fiber connected to OSA is heated using a heater to show the wavelength value, before converted into color. Then convert it into CCT so as to produce a temperature value in kelvins. In this study, singlemode, multimode, singlemode-multimode fiber are used. The connection to each optical fiber and light source uses a Fusion Splicer and Visual Fault Locator with a wavelength of 660 nm and 680 nm, respectively. Results show that the higher the temperature, the farther the wavelength shift. The singlemode-multimode cable has the farthest shift value of 8.44 nm at 660 nm and 9.3 nm at 680 nm. Singlemode-multimode cable has the best measurement accuracy value. Because at a wavelength of 660 nm, the difference between the temperature values ??measured on the thermocouple and those calculated on the matlab has an average percentage of 0.54%. Meanwhile, at a wavelength of 680 nm it is 0.63%.
