Abstract

Ancient inscriptions are historical records of the past were made on stone or metal media. Currently many ancient inscriptions were damaged because for too long buried in the ground. This research is the first step to repairing the damaged inscription using Image processing. Efforts to restoration using ANFIS clustering are an early stage to perform segmentation letters in the inscription. The Results of clustering ANFIS method is compared to the spatial fuzzy clustering method (SFCM). Measuring the performance of clustering is done by measuring root mean square error (RMSE). From RMSE measurements, the average values ??obtained for the measurement of clustering with ANFIS method smaller 21.80% compared to SFCM. This means there is an increase in clustering performance with ANFIS method compared to SFCM. Even so further efforts are needed to improve the clustering quality of metal inscription.

Abstract

This paper  is to perform image enhancement to the spinal x-ray image of people with scoliosis, so that the segmentation process can be done better. Image filtered with Modified Tophat filter were cropped using a vertical windowed Gaussian function with manually initialized center of peak points trough the spinal feature, thus the pixels on the both side of the center of peak points will gradually decrease, leaving only the spinal part. By using this Gaussian cropping, the success rate in segmentation process would increase.

Abstract

Some fish farmers have done a shrimp pond water circulation and turning water wheel, so as to keep the pond water conditions. Fish farmer’s waterwheel turned on at all times, while for the water pump turned on when they found floating shrimp. This method would impact on growth shrimp can be detrimental to the shrimp. So monitoring and controlling the conditions of pond water pond water is continuously required to maintain water quality monitoring and process control pond. This system uses sensors temperature and pH as inputs the system, whereas for the actuator system using water mill, tap lime, and water pump. By using the pH sensor and temperature monitoring and process control an advanced water quality better. Actuators waterwheel, tap lime, and water pumps can alter water quality becomes better. By using tap lime and water pump changes the normal acid pH 7.2 6.65 can be reached within 14 minutes. While the use of the water wheel can change the temperature of 39 ° C to 32 ° C in less than 16 minutes. Thus this system can facilitate farmers to anticipate significant changes in water quality, so that the fish farmers will get maximum results at harvest time.

Abstract

Scoliosis is a spinal abnormalities that bends to S shape or C shape. The proper treatment can make better healing of scoliosis patient. Currently, diagnosis of spinal curvature is using a manual process performed by orthopedic, thus resulting an error in the measurement. To resolve this issue, used segmentation method that using image processing technology. segmentation method is using Charged Particle Model (CPM) which able to perform segmentation properly.

Abstract

Wireless technology atau teknologi nirkabel, atau lebih sering disingkat wireless adalah teknologi elektronika yang beroperasi tanpa kabel. Wireless technology telah dikenal dapat dimanfaatkan untuk komunikasi maupun pengontrolan. Saat ini, teknologi nirkabel juga dapat diterapkan pada proses perpindahan daya atau disebut juga wireless energy transfer.Wireless energy transfer memiliki beberapa macam mekanisme, salah satunya adalah inductive resonant coupling. Teknologi ini bekerja dengan menggunakan efek kopling resonansi antara dua gulungan sirkuit LC. Inductive resonant coupling mampu mentransmisikan energi melalui media magnetic field atau dalam beberapa teori lainnya dikenal dengan fluks yang dihasilkan oleh arus listrik.Inductive resonant coupling mampu menghasilkan nilai daya keluaran hingga 0.021 watt dengan jarak 3 cm dan daya input 0.440 watt. Teknologi ini mampu mencapai tingkat efisiensi sebesar 6.73% pada jarak 3 cm. Sedangkan tingkat efektivitasnya mencapai 0.07 yang berarti daya keluaran lebih kecil 14 kali dibandingkan daya input. Keyword : Wireless Energy Transfer, Inductive Resonant Coupling, Transmisi Daya Listrik.

Abstract

East java is a center of Majapahit kingdom, who has many inscription. One of them is Adan-adan inscription. It was kept in Mpu Tantular museum. The prehistorical of the inscription  was filled with Javanese ancient writing. It finded on few centimeters under land surfaces, because of it many inscription had finded realized broken like rusty on the copper plate line and many of letter scratch then in the others part was lid by rusty, so make the information deliver of the inscription less. The inscription realize texture feature changing on the scratch from Adan-adan plate.This research purpose to classified scratch fiture and inscription plate based on GLRLM feature extract used SVM method in order to differentiate kind of inscription between scratch and brown patina plate and green patina. For decide accuration level in the scratch and brown patina plate and green. It used for SVM classified based on GLRLM feature extract.From GLRLM extract feature trial obtain feature value from the scratch and brown and green patina plate. When feature value from the scratch and brown and green patina plate get different feature, so the scratch and plate can classified. SVM classification based on GLRLM feature extract from scratch get maximum accuration level reached 73,33% and inscription plate get maximum accuration level reached 79,17%.

Abstract

ABSTRACTToday many PDAM are still using water meter reading system manually. Officers come directly to the clients home to record the numbers on the water meter. But in this way the many hurdles that harm customers and the PDAM. The problem that often occurs is when the water meter reading. In this final project will be made a prototype prepaid payment system on PDAM.The system is divided into two. The first is a server, used for prepaid genarate equipped with encryption systems. The second miniature tools. After performing pulse decryption process then water flow sensor do counter calculates the amount of water to come out in accordance with the pulse. When the pulse runs out system will give the command to close the solenoid valve on the faucet. The prepaid system has accuracy rate of 99.9%.Keywords:PDAM, Flow Water Sensor, Solenoid Valve, Pre-Paid System, Arduino Uno R3

Abstract

Stress level measurement using fuzzy logic method is a tool used to measure the level of stress with the parameters of heart rate, body temperature, and blood pressure. Using Arduino Uno R3 as data processor, DS18B20 as the temperature sensor, MPX5050DP as heart rate and blood pressure sensor. The results of the measured parameters are then compared with stress levels table by using fuzzy method as decision makers. Body temperatue measurement using DS18B20 has 99,48 % accuracy rate, while systole blood pressure, diastole blood pressure and heart rate measurements have  91,94 %, 89,59 % and 96,7 % accuracy rate. This system works very well in measuring the level of stress, and the fuzzy system works as expected.

Abstract

                    Hydroponics is one method of farming without using soil in the planting media, but can produces better than soil in general because the result of farm would be more clean and practical. The community usually use this cropping manner for agriculture with a narrow land. Hydroponics now widely used community because it proved profitable and generate maximum agricultural production. In this final task was created the way take care of hydroponics automatically. The design of electronic instrument using the Arduino Mega microcontroller that obtain input from sensors used, and will be processed by an Arduino Mega microcontroller using the setting clean water and nutrient water method automatically.                   The systems designed have been able to to reduce waste of time as well as the performance of the user itself. By simply setting up the water in the backup container, set up water nutrients, and chose nutrients options with the keypad. The tool has been able to do the automation of water charging and nutrients mixing automatically. So tool is able to improve efficiency and effectiveness in the use of nutrients daily. Based on the test results indicate the level of success of this tool in determining the success rate of 100% correctly, and the error rate of this instrument of 0%.Keywords: Arduino Mega, Hydroponics, Water Management.
