Abstract

Telah dilakukan penelitian tentang rancang bangun prototipe monitoring suhu dan kelembaban udara berbasis internet of things (IoT) pada Labratorium Kalibrasi Balai Pengujian dan Sertifikasi Mutu Barang (BPSMB) Samarinda. Penelitian ini bertujuan merancang prototipe yang dapat mengukur suhu dan kelembaban udara menggunakan sensor BME280 berbasis mikrokontoler NodeMCU ESP8266. Tahapan penelitian dilakukan dengan merancang perangkat keras dan perangkat lunak prototipe menggunakan BME280 sebagai sensor yang dapat mengukur suhu dan kelembaban udara dan NodeMCU ESP8266 sebagai kontrol utama yang dilakukan di Laboratorium Elektronika dan Instrumentasi Universitas Mulawarman. Tahap selanjutnya, dilakukan pemantauan suhu dan kelembaban udara di Laboratorium Kaibrasi Balai Pengujian dan Sertifikasi Mutu Barang Samarinda. Hasil perancangan prototipe dapat mengukur suhu dan kelembaban udara seacara realtime serta dapat dimonitoring menggunakan smartphone melalui aplikasi blynk dan hasil monitoring di Laboratorium Kalibrasi BPSMB Samarinda menunjukkan bahwa laboratorium tersebut berada pada suhu ideal yaitu 18 - 22 sesuai standar acuan JIS Z 8710 (Japanese Industrial Standard).

Abstract

Control valve is a tool in the oil and gas industry that works by relying on actuators as a driving force. For example, pneumatic actuators work with air pressure as driving energy, and standard signals are used for pneumatic. The signal is converted into a current signal using fuzzy as an application of artificial intelligence systems in the industrial sector. The method used in this study is the utilization of fuzzy logic with the Mamdani method using the software MATLAB. The results will be compared with data from companies and P/I simulation data. Pressure pneumatic algorithm system fuzzy by paying attention to the range of signals used. Company data and P/I converter simulation data are not much different, but the line equation obtained is slightly different. Meanwhile, the fuzzy logic data has slightly different data from the previous data caused by the rules of the fuzzy. Thus, the use of fuzzy logic pressure pneumatic signals to flow signals can be said to be quite capable of being used in these systems by paying attention to the range of signals and rules needed. The comparison results that have been tested have data results that are not much different based on the difference in the value of the current signal and the error value obtained below 2.5%.

Abstract

This study was done to develop a Yagi antenna for a 1.8 GHz mobile phone using ironwood as a signal booster as an alternative for some local communities. Designing a Yagi antenna for this study's initial phase, which took place at FMIPA Mulawarman University's Electronics and Instrumentation Laboratory, involved considering its size and range. The boom length is 1 m, the driven length is 7.9 cm, the reflector length is 8.4 cm, and the director length is 7.5 cm after calculating the length and distance of the Yagi antenna parts. The distances between the elements are as follows: 4.1 cm separates the reflector from the driven, 2.5 cm separates the driven from director 1, 3.3 cm separates director 1 from director 2, and 4.1 cm separates directors 3 through 9 from each other. The download signal (receiver) and upload signal were the characteristics used in data collection on Batu Besaung, Samarinda, and East Kalimantan (transceiver). During the course of this data collection, ten maximum data collection points were taken in each of the compass' eight directions. In the final step, data processing is done to find out how much gain the designed Yagi antenna produces. The highest rates recorded are 2,27 Mbps download (receiver) and 2,59 Mbps upload (transceiver), both measured at noon at the tenth point and in the south.

Abstract

Heavy metal pollution is still a serious problem today. One method that can be used to remove heavy metal content from water is the adsorption method. In the adsorption method, the choice of adsorbent is very important to optimize the adsorption process. One of the materials that can be used as an adsorbent is tea waste. Tea waste contains cellulose, which can be used to bind heavy metal ions. This research was conducted to synthesize adsorbents using tea waste and then test their ability to adsorb lead ions. The adsorbent synthesis process is divided into several stages, namely washing, drying, refining, soaking in HCl solution, and drying again. The results of the adsorption tests conducted found that the tea waste adsorbent could remove 99% of the lead metal ion content in the water. The conclusion from these results is that the synthesis process has succeeded in making tea waste adsorbent that can adsorb lead ions in water.
