Abstract

Gamelan merupakan salah satu alat musik tradisional dari pulau Jawa. Seperangkat gamelan terdiri dari berbagai macam alat musik yang dimainkan secara bersama-sama. Karena perpaduan antara bunyi gamelan satu dengan bunyi gamelan yang lainnya menggambarkan keselaraasan dalam kehidupan bermasyarakat. Namun seiring berjalannya waktu, peminat gamelan semakin sedikit dan orang pembuat gamelan juga semakin sulit dijumpai.Gamelan yang digunakan dalam penelitian ini yaitu: Gong, Kempul, Kenong dan Bonang Penerus. Bunyi gamelan akan diidentifikasi dengan caramencari frekuensi-frekuensi bunyi gamelannya. Dengan menggunakan metode Fast Fourier Transform (FFT) suatu bunyi yang berdomain waktu dapat diubah menjadi domain frekuensi dengan salah satu software Matlab.Proses dalam jaringan syaraf tiruan Backpropagation ini menggunakan jumlah neuron yang bervariasi, diantaranya: 70, 80, 90, 100 dan 110 untuk mengetahui keakuratan jaringan dalam mengenali data yang diujikan. Hanya jumlah neuron 110 lah yang dapat mengenali data pengujian sebesar 99% untuk data pengujian pelatihan dengan MSE 0.0001233 pada epoch ke 1000. Maka hasil dalam penelitian ini jaringan dapat mengenali data pengujian dengan benar. Sehingga mengidentifikasi spektrum bunyi menggunakan jaringan syaraf tiruan dapat digunakan untuk mengenali berbagai bunyi gamelan bahkan bunyi yang lainnya.

Abstract

kWhmeter adalah suatu alat ukur energi listrik yang mengukur secara langsung hasil kali tegangan, arus, faktor kerja, dan waktu yang bekerja selama jangka waktu tertentu. Pengukuran energi yang dominan adalah pengukuran arus, di mana arus yang diukur melebihi arus yang terdapat di kWh meter. Untuk itu dibutuhkan suatu peralatan instrumen yang dapat menurunkan arus yaitu trafo arus. Susut distribusi pada sistem kelistrikan dapat terjadi pada alat pengukur dan pembatas (APP) yang dipergunakan dalam transaksi tenaga listrik dengan pelanggan. Susut yang terjadi pada APP ditentukan oleh akurasi APP dan akurasi pembacaan atau pengambilan data hasil pengukuran. Untuk menghindari atau mengurangi susut tersebut pemilihan trafo arus yang tepat sangat dibutuhkan seperti mengamati seberapa besar ketelitian trafo arus dalam pengukuran. Kelas ketelitian trafo arus, burden, kesalahan sudut, dan juga arus nominal dari sisi primer trafo arus harus diperhatikan. Jika pemilihan tidak sesuai, maka akan memungkinkan terjadinya susut.

Abstract

Adiel Megido, Eko Ariyanto  in this paper explain that the temperature control system on water heaters that use electric heaters, generally uses ON-OFF voltage control. Apart from this system being less efficient in using electricity, the limited range of voltage settings provided also lacks the output accuracy value required by the control system. So that for some applications it can cause a response to the temperature control system that oscillates. Another alternative in controlling the heating voltage is by using the PID control method (Proportional - Integral - Derifative), this method provides a wider range of voltage settings, so that it can provide the output accuracy value needed by the control system, thus making it possible to obtain system responses finer (minimum oscillation amplitude). In addition to problems with the temperature control system, the water volume control system in the water heater tank generally still uses probes that are installed at certain levels. The limitations in reading each change in height / volume of water causes the system output to be less linear (discrete). To produce linear readings and outputs in each change in water volume, a voltage divider can be used. In this final project design will use an electric water heater tank as a medium to determine the ability of the PID controller to control water temperature according to the set-point and control the height / volume of water in the tank using a voltage divider. Keywords : PID (Proporsional – Integral – Derifatif), Berosilasi, Set-pointReferencesMalvino, Albert Paul. 1981.

Abstract

Ade Siti Sarah Azhar,  Eko Ariyanto in this paper explain that Coffee is one of the most popular drinks ever in the history of human civilization. Roasting is one of the most important processes in processing coffee beans that serves to determine the process of forming flavors and aromas in coffee beans. The average roasting process still uses manual methods, so an automatic coffee roaster machine is needed that can support the home roasting process which is equipped with a round control system. It is expected that the roasting process can be carried out quickly. The use of automatic roasting machines aims to save energy and cost and time efficiency. The round control system in this coffee roaster machine uses PWM (Pulse Width Modulation) to regulate speed on a DC motor by regulating the PWM signal which can be done in analog or by using a microcontroller.By using a motor driver, the motor rotation direction can be controlled. When the DC motor rotates its rotation speed can be detected by an optocoupler which then outputs from the optocoupler will send and process data to the Atmega microcontroller 16. The performance of this control system uses a rotation above 60 Rpm with regulated temperatures above 100 ° C. The performance of this control system gets variations in the results of roasting of coffee beans that are close to the standard of coffee, namely at the rotation of 65 Rpm with a temperature of 130 ° C and the roasting time of 18 minutes with the color of Light Roast coffee beans.  Keywords :Speed Control, PWM, DC Motor, Driver Motor, Optocoupler, Mikrocontroller Atmega 16.ReferencesBahroin,  Anaitul dan Agung Prijo Budijono. 2013.

Abstract

Muhammad Adi Gumelar B, Eko Ariyanto, SCADA is one tool that can monitor and control the system at the substation and can coordinate the protection system area when a disturbance occurs. SCADA monitors the device continuously. This paper is to understand Differential protection areas, CCP, Buspro, and CBF that work when there is interference, namely internal and external interference by applying SCADA as its coordination. 12V DC relay is used as PMT, ACS712 as CT, and Ethernet Shield as Modbus to connect Arduino Mega 2560 with SCADA. Arduino Mega 2560 functions as a controlling center of input and output. The input used is the ACS712 sensor as a detector of the current flowing in the circuit. The Arduino Mega 2560 output signal will be sent to SCADA using an Ethernet Shield and router. Status of substations 1.5 breakers can be monitored with HMI from anywhere by using the SCADA application. In the event of a disturbance, each ACS712 will start reading the current changes and will be processed by Arduino Mega 2560, so that it can determine the protection area that works and trip the relay, SCADA will automatically record disturbances and give an alarm to occur by turning on the protection LED and sounding buzzer alarm.
