Abstract

The development of wireless technology has created a new network, namely the MANET network. In a MANET network, a node can be a router or an end user because in a MANET network the node is flexible. MANET networks have proactive OLSR and BATMAN protocols. When a node becomes a router, many other nodes will pass it. This research was conducted to determine the formation of the router node in the middle, namely the router that is passed by a lot of communication and the edge, that is, the router that has little communication through the network using parameters of CPU usage, RAM usage, and processing delay. From the test results, the CPU value on OLSR and BATMAN for the middle router node is 0.3 and for the edge router it is 0.2 when communicating, when there is no communication the CPU value on OLSR is still 0.3 while in BATMAN the BATMAN value drops to 0.2. For memory used in both protocols get 0.0 because the router only forwards packets without needing to process the packet. For processing delay in the two protocols, the value varies because packet delivery has an uncertain delivery interval between packets. In BATMAN protocol, CPU usage is better than OLSR because if there is no data communication, the CPU value from BATMAN goes down and on OLSR there is no fixed CPU value communication.

Abstract

Macrobending often occurs in optical fibers that embedded in the ground due to shifting of soil or rocks in the ground causing interference in transmission. In this study used single-mode-multimode-singlemode fiber optic cable connected manually and axially measured using a light source test equipment and optical power meter and the results will be compared. The measurement results obtained the greater value of macrobending losses with the smaller the diameter of the winding, and the greater the number of turns. The highest value of macrobending losses in multimode cables is -1.48dB at 0.5cm diameter with 5 turns, highest value of macrobending losses on single mode cables is -12.73dB at 0.5cm diameter with 5 turns, lowest value of macrobending losses for multimode cables is -0.44dB at 5cm diameter with 1 twist, lowest macrobending losses in singlemode cables is -1.69dB at 5cm diameter with 1 twist. While the value of macrobending losses on axially connected SMS cables shows the highest value of macrobending losses on multimode cables is -1.12dB in diameter of 0.5cm with 5 turns, highest value of macrobending losses on singlemode cables is -1.18dB at diameter of 0.5cm with 5 turns, lowest value for macrobending losses on multimode cables is -0.66dB at 5cm in diameter with 1 twist, the smallest value for macrobending losses on singlemode cables is -0.27dB at 5cm diameter with 1 twist . The measurement results also showed that the macrobending losses of manually connected SMS cables were greater than the macrobending losses of axially connected SMS cables.

Abstract

Mangrove forests have high ecological, economic and social values ??which function to maintain shoreline stability, protect beaches and riverbanks, filter and remediate waste, and to withstand floods and waves. The facts show that mangrove damage is everywhere, even the intensity of damage and its area tends to increase significantly. Many roles of mangroves require proper management to maintain the existence of mangroves. One way to determine the area of ??mangroves is by processing Landsat 8 satellite imagery. The stages of mangrove identification are carried out by using 564 RGB band merger, then separating the mangrove and non-mangrove objects. Next step is to analyze the density of mangroves using NDVI formula. To maximize monitoring of mangrove area, an android application was created that provides information on the area and density of mangroves at several locations, namely Clungup, Bangsong Teluk Asmara and Cengkrong from 2015 to 2018.The results showed that Landsat 8 satellite imagery can be used to identify changes in the area of ??mangrove forests with good accuracy, namely in the Clungup area of ??90% and Cengkrong of 86.67%. From processing results, the mangrove area in the Clungup area has also decreased from 2015 to 2017 but has increased in 2018 so that the application provides recommendations for embroidering mangroves in 2016 to 2017 and mangrove recommendations are maintained in 2018. As for Bangsong Teluk area Asmara and Cengkrong have increased the area of ??mangroves every year so that the application provides recommendations to be maintained from 2016 to 2018.

Abstract

Currently, public transportation is needed by Indonesian people to meet human needs for increased movement or mobility. Along with the increasing public interest in trains demanding an increase in services such as the checking system for passenger tickets still using manual system by officers by approaching passengers in each car. This is'nt efficient, so an automatic passenger ticket inspection system using RFID is required. Passenger RFID is scanned when check-in at station then the data is sent to server via nodeMCU ESP8266, the officer only checks passengers through the data display on the monitor. This system also has a Flex sensor in each seat which functions to detect seats that aren't purchased but are occupied by other passengers.The test results concluded that the reading of the RFID card against RFID reader reached distance and barrier with a thickness of 3cm, the DHT11 temperature sensor showed reading accuracy up to 96.6%, and the voltage on the flex sensor on seat 1 had average load of 2.6V, seat 2 average 2.82V, seat 3 averaged 2.84V, seat 4 averaged 2.67V, while the voltage on the flex sensor in seat 1 had an average load of 2.38V, seat 2 averaged 2.29V , seat 3 averages 2.65V, seat 4 averages 2.60V. The value of the flex sensor tension in each condition isn't the same for each seat because the surface shape and thickness of each chair are different. All systems can run properly, starting from sensor readings, transmitting data and displaying data on web.

Abstract

Optical fiber is a transmission medium for sending information that uses light as a source of information. Optical fiber can be used as a transmission medium to transmit information in the form of data, video and voice. Of the various kinds of light sources used, the most bpouler used is laser. Even though there are still many light sources used, namely leds. In this research, the design of a sound transmission transmission system is designed, but by using a led light source with different colors. With different colors means the wavelength of the led is also different. This affects the amount of information conveyed at the receiving end. The results showed unsatisfactory results, due to the limited standard of existing components and the angle of light reception that did not meet the standards from the optical fiber reception angle. However, there are several results from the study, namely the value of reinforcement from the sender's side has a difference of 2.4. In the measurement of the SNR value, the SNR value of the LED is greater than the SNR value of the laser when without using a cable of 0.1387 and when using a measuring cable of 3.5924 x 10-5. Then also generated a reinforcement response to changes in the frequency value. The greater the frequency value, the lower the gain.

Abstract

In the cultivation of milkfish, water quality is very concerned about in order to minimize fish mortality when cultivated. Several important factors in the cultivation of milkfish are the level of salt content in the water, temperature and pH. Currently, farmers monitor water quality manually by coming directly to see water quality. If there are dead fish, the cultivator will replace the new water. This will have an impact on fish production which will decrease. The milkfish pond uses brackish water for pond waters. The salt content is between the sea water content and the fresh water content. The grade level may change from season to season. This change is due to biological processes that occur in these waters as well as the interaction between pond waters and the surrounding environment. The results showed that the results of the design of the salt concentration monitoring system in the milkfish ponds that have been carried out using Arduino Uno, conductivity sensors, pH sensors, temperature sensors, wifi modules, Mi-Fi and Smartphones to access android applications. The results of testing the microcontroller functionality that have been made are in accordance with the design and are running well. The system designed to transmit information in the form of salinity values, pH sensors, temperature sensors and TDS values ??with sensor accuracy that is linear with measurement results using conventional measuring instruments with the highest error values ??of 1.3%, 2.06%, 0.702% and 1.5 respectively. %.

Abstract

Jamu chili or Javanese chili (Piper retrofractum Vahl.) Is a medicinal plant that has been used since ancient times as an ingredient in cooking, drinks and traditional medicine, such as to treat low blood pressure, colds, impotence as well as to clean the uterus after childbirth. . Besides herbal chilies as medicinal plants, the price of herbal chilies is expensive and their production is utilized domestically and exported to, among others, Singapore, Hong Kong, Malaysia and India. Herbal chilli plantations are spread across all districts, especially in Madura Island, namely in Sumenep District 1,709 ha, Sampang 1,017 ha, Pamekasan 715 ha and Bangkalan 356 ha. In Lamongan Regency, there is an area of ??276 ha. The area of ??herbal chilies in Lampung Province is 630 ha. However, despite the many benefits and have been exported abroad, the herbal chili plants have not been well controlled by the farmers, which causes the herbal chili plants to die before they bear fruit. In this research, a web-based monitoring system design will be made based on the level of soil acidity and soil moisture. The sensor for soil acidity uses a pH meter and for soil moisture uses a soil moisture sensor. Data will be stored in the database and displayed on the web. Soil acidity and soil moisture data will be sent via the internet to the database.

Abstract

Loyal customers at a restaurant definitely want a reward for their loyalty to the restaurant, Moshi-Moshi Ramen created the Loyal Customers program as an appreciation for loyal customers. The program is made using a paper card with 10 empty boxes which is stamped by the cashier when the customer pays for food. The current era of globalization allows all areas of life to be assisted by the presence of technology. One of the technologies developed in the culinary field is the design of a digital loyal customer card system based on Radio Frequency Identifier (RFID) which has been linked to the Firebase web database as a medium for storing data. It was found that there were deficiencies in the loyalty program, namely the card that was not safe to hold, especially if the card was lost, the customer could not claim the number of stamps So, to solve this problem, RFID and pin numbers are used as a safer system of loyal customer cards and the database for storing registered customer data to transform the existing loyalty customer program into a smarter system. Making a digital loyal customer card system using an RFID tag can be done using the Arduino Uno R3 microcontroller which has a reading sensitivity of up to a distance of 4.5 cm and an android application for ordering food. As well as all functions that can run well, including comparison of transaction times using manual and digital systems with a time difference of 10 seconds.
