Abstract

Aquaponics is an integrated system that combines fish farming and plant cultivation in a mutually beneficial ecosystem. In this system, plants utilize nutrients produced from fish waste, while also helping to maintain water quality. However, farmers often face difficulties in managing water pH and feeding fish due to their busy schedules or other activities. And also excess feeding can accelerate changes in pond pH. This is because the remaining uneaten feed will decompose in the water, resulting in ammonia compounds that have the potential to increase the pH in the pond. Therefore, this research aims to design an automated device to regulate feeding and control water pH. Arduino is used as the central controller to manage sensors and automate the system. Water quality is measured using a pH sensor with an accuracy level of 95%. The pH control system in fish ponds functions to maintain water quality at the optimal range for fish health. Feeding is carried out according to a set schedule, and the feed throwing distance is adjusted based on voltage. The results of this system show that water pH remains stable, fish and plants are in good condition, and it helps farmers easily maintain water quality and nutrients for both fish and plants. Thus, this device can provide a practical solution for farmers needing automation in the aquaponics process.

Abstract

Penggunaan komputer beserta beberapa program aplikasinya dalam dunia pendidikan pada zaman sekarang merupakan sesuatu yang tidak asing lagi. Hal ini sejalan tuntutan peningkatan kualitas kemampuan para guru dalam membuat dan menyajikan bahan ajar merupakan suatu hal yang perlu untuk direspon para guru. Para guru diharapkan memanfaatkan komputer dalam mengemas materi ajar dalam bentuk bahan ajar yang akan dikomunikasikan kepada para siswa. Agar materi ajar yang akan ditransfer menjadi suatu pengetahuan dan mudah diserap secara maksimal oleh anak didik, maka peran bentuk dan media penyajian materi merupakan hal yang tidak bisa diabaikan. Untuk itu diperlukan suatu pelatihan pembuatan file-file presentasi yang lebih menarik dan komunikatif. Selain hal di atas, maka perlu pula mengadakan pelatihan atau kursus singkat mengenai cara membuat blog bagi para guru dan siswa untuk mengoptimalkan proses belajar-mengajar di sekolah.

Abstract

Peralatan audio digital menjadi bagian yang tidak terpisahkan untuk mendukung kelancaran kegiatan belajar mengajar maupun acara lomba-lomba yang diselenggarakan di Sekolah ataupun di Pondok Pesantren. Penggunaan peralatan audio juga perlu memperhatikan lokasi ruangannya (indoor atau outdoor), posisi pendengar dan spesifikasi peralatan audionya. Pondok Pesantren Tahfidzul Qur’an Darul Wafa Mataram termasuk sekolah penghafal Al Qur’an yang memanfaatkan teknologi audio digital untuk menunjang kegiatan belajar mengajar, ujian tahfidzul quran dan lomba lomba Musabaqah Tilawatil Qur’an (MTQ) yang biasanya diadakan di aula sekolah. Namun peralatan audio yang tersedia masih belum maksimal sehingga kualitas audio yang dihasilkan juga belum optimal. Pengeras suara yang dimiliki sebanyak 1 buah dengan daya sebesar 120 watt, kondisi pengaturan audio ini masih kurang sehingga perlu peningkatan kualitas manajemen audio melalui kegiatan Pengabdian Pada Masyarakat. Kegiatannya dalam bentuk pelatihan yang dapat memberi pengetahuan dan keterampilan dalam manajemen audio digital, berupa pelatihan instalasi, revitalisasi peralatan, pemberian workshop dalam penggunaan dan perawatan peralatan audio kepada Pengelola Pondok Pesantren Tahfidzul Qur’an Darul Wafa Mataram. Hasil kegiatannya menunjukkan bahwa kualitas audio yang dihasilkan semakin baik dari sebelumnya dan dapat digunakan untuk mendukung kegiatan belajar mengajar serta kegiatan lomba tahfidzul Qur’an. Selain itu daya audio yang dihasilkan bertambah menjadi 240 watt.

Abstract

This research aims to deepen understanding of theory in lectures through practicum. The practicum module was created to facilitate data retrieval during a practicum at the Electronics and Digital Laboratory, Faculty of Electrical Engineering, University of Mataram, which was realized in the design of the logic gate and flip-flop experiment module, based on the logic gate and flip-flop experiment module, on logic gates using 7 IC namely AND gate (IC 7408), OR gate IC (IC 7432), NOT gate IC (IC 7404), NAND gate IC (IC 7400), NOR gate IC (IC 7402), XOR gate IC (IC 7486), XNOR gate IC (IC 74266), resistors, led indicators, and switches, on Flip-Flops using 2 logic gate ICs namely NOT gate IC (IC 7404), NAND gate IC (IC 7400), and a JK Flip- Flops (IC 7476), and clocks that use push buttons that have been connected to Arduino, resistors, led indicators, and switches, from the designed modules, the results show that the logic gates and flip-flop experiments are by the experimental steps and the truth table his.

Abstract

Design of the seven segment and shift register experimental module. The aim of designing this tool is to make it easier for Electrical Engineering students at Mataram University to retrieve data during practicum. Previously, students needed a long time to collect data, 20-30 minutes, after the existence of this tool, students only needed 10-15 minutes to collec data. In the data seven-segment experiment, the output displayed a seven segment display, while in the shift register experiment the output is shown by an LED indicator, including several subs such as the right shift register, left shift register, and circular shift register. This design uses IC MC14495, 7476, 7432, 7404 and 7408 equipped with several other components... so that output results are obtained that match the input provided.

Abstract

This study analyzes the performance of a speaker recognition system based on Hidden Markov Models (HMM) using Fast Fourier Transform (FFT) for feature extraction. The objective of this research is to evaluate the effect of the number of FFT samples on the recognition accuracy. Experiments were conducted using speech signal test data with variations in the number of speakers ranging from 2 to 10, and variations in the number of FFT samples of 2, 4, 8, 16, 32, 64, 128, and 256 samples per state.The results indicate that the number of FFT samples significantly affects system accuracy. Using a small number of FFT samples results in low and unstable accuracy, especially as the number of speakers increases. Increasing the number of FFT samples improves both accuracy and stability of the system. The highest and most consistent performance is achieved when using 64 to 128 samples per state. Increasing the number of samples beyond this range does not lead to a significant improvement in accuracy, indicating a saturation effect. These findings demonstrate that selecting an appropriate number of FFT samples is essential for achieving optimal performance in HMM-based speaker recognition systems, with 64 to 128 samples per state recommended as the optimal configuration.
