Abstract

Dengan banyaknya pemakaian Liquid Petroleum Gas (LPG) untuk rumah tangga, usaha kecil, dan industri mikro maka potensi resiko atas penggunaan LPG juga akan timbul. Minimnya upaya masyarakat sebagai pemakai LPG dalam mencegah terjadinya kebocoran gas membuat kasus kebakaran akibat LPG marak terjadi, setidaknya perlu ada tindakan dalam menanggulangi hal tersebut untuk meminimalisir sesuatu yang tidak diinginkan terjadi selanjutnya. Resiko kebakaran atau ledakan akibat kebocoran LPG dapat dihindari apabila ada pencegahan dini, saat gas keluar atau pada saat pada kebocoran gas terjadi. Pada penelitian ini dikembangkanlah sebuah sistem keamanan dengan cara memberikan sistem peringatan untuk memberikan sebuah tanda jika terjadi kebocoran gas di dalam rumah. Jika sistem ini mendeteksi adanya kandungan LPG maka sistem akan memberikan sebuah tanda peringatan berupa alarm. Pengembangan berupa purwarupa bersifat portabel yang dapat membantu dalam pendeteksian kebocoran gas dengan menggunakan beberapa modul elektronik sehingga menjadi suatu sistem alat terintegrasi yang mampu memberikan suatu peringatan berupa alarm. Purwarupa menggunakan mikrokontroler Arduino Uno sebagai algoritma sistem dan Sensor MQ-2 sebagai pendeteksi kebocoran gas. Jika tingkat kebocoran melebihi batasan tertentu maka sistem akan menyalakan alarm dan mengaktifkan kipas untuk membuang konsentrasi gas pada ruangan. Untuk menampilkan parameter terukur digunakan LED display.

Abstract

Citrus fruit is a fruit that is favored by the public. The quality of the fruit from the garden to the consumer goes through a long process. Generally, the quality of the fruit is evaluated by a visual judgment ratio that can be wrong. This method also only evaluates the external quality of the fruit. The internal quality of the fruit such as sugar content is determined by a refractometer which belongs to the destructive method, and is not suitable for online quality measurement. A non-destructive and objective method to evaluate the quality of citrus fruits is needed. Electrical Impedance Spectroscopy (EIS) method can be used in non-destructive investigation. In this study, a non-destructive measurement of pamelo orange fruit was developed. The impedance change of pamelo citrus fruits during ripening was observed over a period of one week. The impedance of pamelo orange fruit was measured by AD5933 evaluation board and then the measurement data was analyzed by EIS Spectrum Analyzer software. Frequency-related electrical characteristics were observed, the results showed that the electrical impedance decreased and the phase increased

Abstract

Photovoltaic (PV) temperature is an important parameter that can influence PV performance. The increase in PV temperature can cause a drop in PV output voltage, which indicates that the PV does not operate optimally. In this paper, a design of an integrated cooling system based on fuzzy logic to control the PV temperature is presented. This, in effect, will potentially ensure that the PV performance is at its maximum condition. In this work, the temperature of the PV is kept constant by attaching a cooling system that carries water inside it. The constant temperature of the cooling system is carried out through a radiator and thermoelectric with electronic control. The experiments are carried out using two 320-watt PV systems; one with the cooling mechanism and the latter without the cooling system as a control. Several important data such as temperature, voltage, current, and radiation measurement in each PV were collected for three days from 10:00 to 17:00 with an interval of 10 minutes for each measurement. The results of the integrated cooling system measurement showed an increase in PV power generation and efficiency of 1.32% compared to the control PV unit. From the results of the study, it can be concluded that the fuzzy logic-controlled cooling system contributed to the increase in PV performance.
