Abstract

Monitoring and control all process variables such as power, temperature, and pressure is an absolute necessity in the field of industry. Instrumentation is a tool that can be used to monitor and control the process variables. From the monitoring results it can be seen whether the system is running in accordance with the desired or not. If deviation occurs, then the control action is needed so that the process can run as expected (the operating control system). One of the instrumentation equipment that need to be investigated is the use of laser deflection, because the laser beam that has a coherent nature, so that this instrumentation can be a very useful tool in the industry. At that stage the second year of this research study focused on the process input and data analysis with the aid of a microcontroller as a stage before applied in the modeling industry. The study was conducted in two stages, namely the manufacture of the ADC program that can send data voltage to the computer via RS 232 serial cable and making the ADC data acquisition software in the computer so the computer can act as a collection station, storage, and display data. This software use Borland Delphi 7. The results showed that the graph can be known voltage variations can indicate changes in certain deflection. The value of this deflection will determine the temperature of which is shown by the graph. Changes in the analog signal from the source of the potentiometer into a digital signal using ADC is inversely proportional, which is indicated by a linear graph with a correlation R = 0.99079 Graph showing the relationship between deflection with temperature according to the graph of the results of previous years of research that is done manually. Thus, further stay pending the outcome of the development of an acceptable deflection pattern detector equipped with a data acquisition system, as the final stage before implemented in the industry. Data acquisition system consists of two parts: signal conditioning systems and interfaces. If the detector is subjected by a laser beam, the optical signal is converted into electrical signals. This causes an electrical current. Because the electric current generated by the detector is very small, it needs to be strengthened and transformed into voltage by a signal conditioning system.Temperatures are measured in a particular room will cause the laser beam deflection at a certain distance so it can be used for high temperature control system.   Keywords: ADC, Instrumentation, He-Ne Laser, Borland Delphi

Abstract

The design of audio bio harmonic (ABH) with smartchip WT5001 using solar cell technology in the form of ABH instrumentation with an electricity resource derived from solar energy has been successfully created and tested, which includes (i) testing the peak frequency of sound and sound output, and (ii) emptying and charging tests to determine the effectiveness of the use of the solar cell as the power provider. The ABH system consists of (i) a sound generator device composed of WT5001 sound modules, amplifiers, and horn speakers, and (ii) structured power supply devices for solar cell modules, charger controllers, and batteries for storing power. The test results of the peak frequency for the insect (garengpung) sound files and the output sound of the ABH device indicate a deviation of peak frequency of 13.46 Hz to140.81 Hz. The 15 hours emptying test results in on mode with battery charging for 7 hours shows that the use of 10Wp solar cell is effective to provide electrical power in ABH tool operation.

Abstract

Aplikasi teknologi gelombang akustik dalam bidang pertanian dapat digunakan untuk meningkatkan ketahanan pangan suatu masyarakat. Rekayasa dan modifikasi teknologi audio, yakni audio organic growth system (AOGS), yang dipadukan dengan pemupukan daun (foliar) dan optimasi variabel intensitas audio telah digunakan untuk meningkatkan produktivitas dan kualitas tanaman perkebunan. Kegunaan utama sistem AOGS adalah sebagai input device dalam pembukaan stomata daun tanaman perkebunan. Kendala utama dalam penerapan AOGS di lapangan adalah perangkat elektronik yang digunakan belum praktis dan belum compatible. Selain itu, instrumen AOGS yang terdiri dari audio player dan speaker ternyata cukup berat. Dalam penelitian ini, telah dihasilkan instrumentasi smart chip AOGS (SC-AOGS) dengan komponen TDA2003 sebagai penguat audio, WT5001 sebagai penyimpan dan pemutar audio, ATMega328 kecepatan 16 MHz sebagai prosesor, speaker sebagai sumber ouput dari suara, dan LCD matrik ukuran 16 × 2 yang menghasilkan display sumber frekuensi output yang dipaparkan. Instrumen SC-AOGS ini juga dilengkapi dengan pengaturan volume suara. Lebih jauh, instrumen SC-AOGS ini cukup praktis dan compatible sehingga dapat mengatasi kendala pada instrumen AOGS. AbstractThe application of acoustic wave technology for agriculture purposes may be used to strengthen the food persistency in the society. The creation and modification of audio technology, which is in this case, the audio organicgrowth system (AOGS) combined with foliar fertilization and audio intensity variable optimization has been applied to increase the quality and productivity of plantation crops. The AOGS system is mainly used as aninput device in the leaf stomata opening of plantation crops. However, the main obstacle in the application of AOGS is the electronic devices which are not practical and compatible. Moreover, the AOGS instrument whichconsists of an audio player and a speaker turns out to be quite heavy. Hence, in this research, a smart chip AOGS (SC-AOGS) has been produced equipped with components of TDA2003 as an audio amplifier, WT5001as a storage and audio player, ATMega328 16 MHz as a processor, a speaker as an output source of the sound, and a matrix LCD with dimension of 16 × 2 that produces output frequency source display. Moreover, the SC-AOGS instrument is also equipped with sound volume setting. The SC-AOGS instrument is quite easy to use and compatible, hence may overcome the problem of the AOGS system.

Abstract

Beberapa daerah di Wonogiri memiliki tanah yang mengandung kapur, sementara itu sebagian masyarakat mengonsumsi air yang berasal dari dalam tanah. Pada kegiatan pengabdian kepada masyarakat tahun 2016 ditemukan permasalahan dalam masyarakat di kelurahan Wonogiri yaitu sulitnya mendeteksi adanya kapur dalam air yang mereka konsumsi. Sebagai akibatnya banyak masyarakat yang menderita penyakit dalam yang diakibatkan pengendapan kapur di dalam tubuh mereka seperti penyakit ginjal. Oleh karenanya, tim PPM Fakultas MIPA Universitas Negeri Yogyakarta membangun sistem pendeteksi adanya kapur dalam cairan berbasis Light Emitting Diode (LED) dan Light Dependent Resistor (LDR). LED digunakan untuk menyinari cairan dengan kadar kapur yang berbeda-beda, kemudian LDR akan mendeteksi cahaya LED yang melewati cairan tersebut. Besar kecilnya nilai luaran LDR akan bergantung kadar kapur dalam cairan. Masyarakat sangat antusias dan mulai menggunakan alat ini untuk mendeteksi adanya kapur di air yang mereka konsumsi. Kata kunci: Kesadahan, LDR, LED Workshop On Detector of Water Hardness Based On Light Dependet Resistor In Giritontro Village, Giritontro District, Wonogiri RegencyAbstract           Some areas in Wonogiri contain hardness in its soil, while some people consume water that come from the soil. In community service activity in 2016, we found problems in the community in Giritontro, Wonogiri that is the difficulties to detect the hardness in the water that people consume. As a result, many people who suffer from internal diseases caused by the deposition of lime in their bodies such as kidney disease. Therefore, the PPM team of the Faculty of Mathematics and Natural Sciences of Yogyakarta State University built a hardness detection system in liquid based Light Emitting Diode (LED) and Light Dependent Resistor (LDR). LEDs are used to irradiate fluids with different lime levels, then LDR will detect the LED light passing through the liquid. The size of the LDR output value will depend on the lime content in the liquid. People are very enthusiastic and start using this tool to detect the presence of limestone in the water they consume. Keywords: Hardness, LDR, LED

Abstract

Bird sound classification is a valuable tool in ecological monitoring and species identification, particularly for non-invasive assessment in natural environments. However, challenges such as limited labeled data and environmental noise often reduce the reliability of classification models. This study presents a lightweight bird sound classification pipeline that integrates signal preprocessing, audio augmentation, and machine learning to address these issues. Two bird species with distinct vocal characteristics, Pelung (a crossbreed involving Bangkok chickens) and Canary (Serinus canaria), were used as case subjects. A total of 40 original 2-second audio clips were extracted from longer field recordings, then processed through frame-based energy attenuation, bandpass filtering (1"“8 kHz), and RMS normalization. Ten augmentation techniques were applied to each original file to improve generalization, generating 400 augmented files for model training. Feature extraction was performed using 13-dimensional Mel Frequency Cepstral Coefficients (MFCCs), and Principal Component Analysis (PCA) was used to visualize the effect of filtering. Classification was conducted using a Support Vector Machine (SVM) with a radial basis function (RBF) kernel. Results showed that filtering improved classification accuracy from 90% to 95% on the original data. Furthermore, using only augmented data for training and original data for testing yielded 100% classification accuracy, demonstrating excellent generalization. This study highlights the effectiveness of combining adaptive preprocessing and augmentation for reliable bird sound classification under limited and noisy conditions.
