Abstract

Subak is a traditional organization owned by the Balinese people to manage rice field irrigation. In the process of irrigating the fields, subak administrators and farmers check the condition of the irrigation in the fields by directly coming to the location to check the condition of the water level in the fields, so it is time consuming and less efficient. The creation of a geographic information system is intended so that subak administrators and farmers know the water level of the fields and regulate irrigation without going to the fields. The geographic information system is built using the Laravel framework equipped with a map. The map was created with the Google Maps API with the aim of displaying the location of rice fields. The result of this research is a geographic information system that can monitor the height of rice fields and display data on a map. The information system can also receive sensor data and send configuration data to Antares. In black box testing, the information system has been running according to the functions and scenarios given. Based on the results of the System Usability Scale test, the application obtained a score of 76,125 which indicates the application is classified as good and can be accepted by the user.

Abstract

Some studies such as Aoki measure clock skew by filtering outliers by selecting the minimum offset that is collected using linear regression to calculate the slope of the accumulated minimum offset. Huang who uses the QPM (Quick Piecewise Minimum) algorithm to calculate the skew of the minimum offset at the beginning and end of the collected offsets and Moon's research that uses the LPA (Linear Programming Algorithm) algorithm which determines the clock skew of the line gradient that is below the offset. In addition, there are several methods that have the potential to be used in measuring clock skew including ant colony, bee colony, particle swarm, and also genetic algorithm. From these several methods, one method that has potential as a method that can be used for measuring clock skew will be selected. The method that can be used is particle swarm optimization because it is considered more efficient and flexible and easy to implement with few parameters used.

Abstract

Salah satu bidang yang memanfaatkan data citra adalah di bidang medis,karena citra medis memiliki peranan yang sangat penting dalam dunia medis saat ini., biasanya citra medis membutuhkan penyimpanan yang cukup besar pada komputer dan bertujuan untuk melakukan kompresi pada citra medis menggunakan discrete wavelet  transform (DWT) dan entropy coding (Huffman dan Arithmetic). Lima jenis codec yaitu Coiflet, Symlet, Daubechies, Biorthogonla dan Dmeyer digunakan dalam penelitian ini membandingkan PSNR. Penelitian ini menggunakan nilai threshold 5. Percobaan yang dilakukan menggunakan citra medis yang mewakili jenis citra hasil CT-Scan dan MRI sebagai data testing. Penelitian ini menunjukkan bahwa codec Haar/Daubhecies1, Symlet1 dan Biorthogonal1 memberikan hasil yang lebih baik dalam hal kualitas citra (PSNR).

Abstract

Human life with all its activities cannot be separated from the existence of waste but the quality of post-consumption waste is generally still low. To convert waste into a more stable form and does not pollute the environment, it is required a precise waste collection system. Waste collection system is an important part of waste management. This study is proposed a geographic information system (GIS) application based on google maps Application Programming Interface (API) to map waste collection point using Haversine formula method. The application is designed to develop a waste collection system from households to Temporary Disposal Sites (TDS), quickly and accurately. The application can be used by households and waste taxi bike drivers to communicate when the households need the taxi bike drivers to pick the waste up to the temporary collection points. A geographic information system application based on google maps API used to display the location of the taxi bike driver, TDS and the location of the waste collection (household). Haversine formula is used to get the nearest waste taxi bike driver to the location of the request for waste transportation. The result of this research is an application that can monitor and track waste collection. Using black box testing, the system has run according to the functions and scenarios designed. Based on the testing the system usability scale results, the application obtains a score of 70.125 which indicates that the application is classified as good and acceptable to users.

Abstract

Garbage is an invaluable or worthless object that is around the community environment. Almost all cities in Indonesia experience problems in waste management. This happens because the Final Disposal Site in a city does not have enough land to accommodate. The lack of landfills has resulted in people throwing garbage into ditches, rivers and the sea. Community participation is another important factor in waste management but also necessary to utilize modern technology. Therefore to overcome to overcome this waste problem by creating an Detail Engineering Design for online Garbage Collection System. This system developed to help the process of sending waste from households to TPS and sending garbage from TPS to TPA. The results of this study are detailed engineering systems for online garbage collection which are expected to help local governments in overcoming problems with garbage. With the example of the implementation of this system for Tabanan district. The estimated funds needed are Rp. 20,607,450,400. These funds are used to build a garbage collection site or landfill and develop the application and the time required for the overall construction is six months

Abstract

Keamanan Penerbangan merupakan suatu kondisi untuk melindungi penerbangan dari Tindakan Melawan Hukum melalui perpaduan antara pemanfaatan sumber daya manusia, prosedur dan fasilitas. Terdapat berbagai jenis tindakan melawan hukum dalam dunia penerbangan salah satunya adalah memasuki Daerah Keamanan Tebatas, atau area aeronautika secara tidak sah seperti kasus “Mario” yang melakukan penyusupan perimeter bandar udara sehingga masuk ke roda pesawat Garuda Indonesia pada tahun 2015. Untuk mencegah terjadinya kejadian serupa, maka perlu diterapkan fasilitas keamanan penerbangan dengan teknologi terkini untuk mengantisipasi adanya penyusup yang memasuki Daerah Keamanan Terbatas. salah satunya adalah sistem deteksi penyusup perimeter (PIDS). Dalam penelitian ini, dilakukan perancangan PIDS berbasis IoT dengan menggunakan metode fuzzy logic. PIDS yang dirancang menggunakan mikrokontroler Node MCU ESP8266 dan dilengkapi sensor PIR untuk mendeteksi pergerakan manusia, sensor ultrasonik untuk mengukur jarak, kamera ESP-32, relay, indikator buzzer. Berdasarkan pengujian skenario, kinerja dari dianalisis menggunakan metode confusion matrix dan dapat dinyatakan bahwa prototype sistem pendeteksi penyusup perimeter yang dirancang memiliki akurasi yang baik/good classification (83.33%).

Abstract

OFDM is a transmission technique using orthogonal multi-carrier which can save bandwidth. While MIMO is a technique of using more than one antenna for transmitting and receiving. This can increase data transmission capacity without increasing bandwidth. In this study, an analysis of variations MIMO antennas 2x2, 2x4, 4x2, and 4x4 was carried out to determine the effect of antenna variations on OFDM MIMO performance. The modulation are BPSK and QPSK with frequency selective fading and AWGN channels. Performance parameters are Bit error rate (BER) versus Energy Bit per Noise (Eb/No), Power to Average Peak Ratio (PAPR), and eye diagram. The model simulated using a simulink with a number of input 100,000 bits. The results showed that BER performance compared to Eb/No, in MIMO 2x4 and 4x4 produced better performance than MIMO 2x2 and 4x2. With many receiving antennas, it gets a better signal which can reduce the occurrence of errors. Meanwhile, in PAPR parameter, 4x2 and 4x4 MIMO produce higher PAPR values than 2x2 and 2x4 MIMO. With the number of antennas, the PAPR value is distributed over all antennas and increase the PAPR value in the system. In the eye diagram parameters, the greater the Eb/No value, make a better eye diagram.
