Abstract

The Small Industries Enterprise (SME), which is especially involved in the liquid filling industry (such as mineral water, tea, liquid milk, juice, etc.), needs some device that has the ability to measure liquid automatically and accurately into some container. Based on the 'Water Fall' method, this study carries out a procedure for making compact and efficient tools ('requirements definition' stage), using a keypad start button, flow sensor, temperature sensor, fan, buzzer, LCD 1602, relay driver ('system & software design' stage), implement a schematic drawing of the circuit and install all hardware inside the casing ('implementation and unit testing' stage), install accessories, set parameters and volume target ('integration and system testing ' stage) and re-calibrate the device ('operation and maintenance' stage). After the measurement experiment, we got that Fillco (the name of the device) has a bigger error for measurement below 1000 ml (0.6-15%) and better accuracy measurement for targeted volume upper than 1000 ml (0.04-0.20%). Fillco also able to memorize and reset liquid volume.

Abstract

Differential quadrature phase-shift keying (DQPSK) modulation methods and variations are commonly used in wireless communication, including high-speed optical fiber, Bluetooth, and satellite communication. DQPSK cannot be isolated from possible interference with its present application. The interference cancellation process has been observed and analyzed using a device model built in this study. The core components of the supporting block for this device model have raised cosine filters for pulse shaping and adaptive filters. The presence of these core components has resulted in a dramatic improvement in device efficiency, according to robust Simulink data. The best bit error rate (BER) of 5.7e-03 provides evidence of this.

Abstract

An electrocardiogram (ECG) is a means of measuring and monitoring important signals from heart activity. One of the major biomedical signal issues such as ECG is the issue of separating the desired signal from noise or interference. Different kinds of digital filters are used to distinguish the signal components from the unwanted frequency range to the ECG signal. To address the question of noise to the ECG signal, in this paper the digital notch filter IIR 47 Hz is designed and simulated to demonstrate the elimination of 47 Hz noise to obtain an accurate ECG signal. The full architecture of the structure and coefficient of the IIR notch filter was carried out using the FDA Tool. Then the model is finished with the help of Simulink and the MATLAB script was to filter out the 47 Hz noise from the signal of ECG. For this purpose, the normalized least mean square (NLMS) algorithm was used. The results indicate that before being filtered and after being filtered it clearly shows the elimination of 47 Hz noise in the signal of the ECG. These results also show the accuracy of the design technique and provide an easy model to filter out noise in the ECG signal.

Abstract

Era revolusi industri 4.0 telah menghadirkan banyak percepatan terhadap perkembangan teknologi sehingga menjadi lebih mudah, cepat, dan praktis. Salah satu penerapan teknologi tersebut salah satunya dibidang pendidikan, berupa perancangan model simulasi alat pendeteksi kebocoran gas dan kebakaran sebagai media pendukung pembelajaran menggunakan modul mikrokontroler serta mengintegrasikannya ke dalam saluran komunikasi data internet agar siswa dapat melakukan pengujian dan pemantauan secara real time melalui perangkat mobile. Perancangan model simulasi ini menggunakan modul ESP8266, sensor DHT-11, dan sensor MQ-135. Untuk layanan cloud computing menggunakan database serta aplikasi Thingspeak. Metode yang digunakan pada perancangan ini berupa metode eksperimental. Metode ini banyak digunakan dalam perancangan sebuah sistem karena dapat menguji secara benar hipotesis yang menyangkut hubungan kasual. Berdasarkan hasil pengujian, sistem yang dibangun dapat berfungsi secara baik serta memberikan informasi mengenai nilai kondisi yang sedang diujikan. Siswa dapat memantau kondisi pengujian secara real time melalui aplikasi Thingspeak yang dipasangkan pada perangkat mobile.

Abstract

Internet connections that are not always stable and data security is not maintained from various threats from outside attacks in the form of hackers, crackers, viruses, and so on are the main problems for every client. Using the pfSense analysis method, this study aims to address the above bandwidth management and network security issues. The pfSense analysis that the researchers carried out included an analysis of total bandwidth usage, data security, and information for each client on the P3DW Internet network (Center for Regional Revenue Management) Bandung III Soekarno-Hatta City. The results of the analysis concluded that pfSense can work as a firewall that functions as a bandwidth limiter and network security. The level of client satisfaction increases with the infrastructure designs being tested. With a web GUI that makes it easy for users to configure, the basic system used is FreeBSD which is open-source, making pfSense able to be an alternative choice for building a firewall that is reliable, flexible, and economical.

Abstract

Di dalam sektor industri terdapat sumber potensi yang dapat memicu terjadinya kebakaran. Kebakaran di tempat kerja dapat membawa konsekuensi yang berdampak merugikan banyak pihak. Fire alarm system merupakan sebuah sistem yang dirancang untuk memberikan early warning  terjadinya kebakaran atau gejala terjadinya kebakaran kepada pekerja di dalam bangunan gedung. Untuk itu keakurasian dan kecepatan dalam membaca titik yang menyebabkan kebakaran harus diperhitungkan khususnya pada pemakaian sensor, kabel transmisi data, serta pemetaan suatu area. Pada penelitian ini, alat dirancang dan direalisasikan menggunakan sensor gas tipe MQ-135. Sensor gas MQ-135 merupakan jenis sensor kimia yang sensitif terhadap gas dalam tabung LPG, alkohol, benzol, gas, dan lain-lain. Sensor gas MQ-135 nantinya akan dilengkapi dengan sensor suhu (DHT-11). Indikasi kebakaran yang diperoleh ditampilkan pada aplikasi antarmuka Visual Basic, tiga buah LED, buzzer dan motor DC. Hasil pengujian pada  realisasi sistem menunjukkan sensor MQ-135 dan DHT-11 mampu berfungsi dengan baik pada berbagai jarak uji. Begitu pula dengan aplikasi antarmuka yang dapat menampilkan informasi sesuai data pembacaan pada sistem.
