Abstract

Untuk penanganan virus corona dimasa pandemi ini, Pemerintah menghimbau kepada masyarakat untuk senantiasa mematuhi dan disiplin menjalankan protokol kesehatan yaitu salah satunya dengan senantiasa mencuci tangan dengan air bersih yang mengalir. Pada penelitian ini dirancang sebuah mesin cuci tangan otomatis yang dilengkapi dengan kran air, sabun cuci cair, hand drayer, dan hand sanitizer yang otomatis, serta dfplayer mini dan speaker membuat mesin ini lebih interaktif dengan mengeluarkan suara untuk memandu penggunaan alat. Dalam pengoperasiannya, tidak ada lagi sentuhan tangan dengan alat namun setiap bagiannya akan berfungsi otomatis sesuai fungsinya masing-masing. Untuk mendeteksi keberadaan tangan digunakan sensor proximity, dan hasil penelitian menujukkan bahwa jarak untuk mendeteksi keberadaan tangan adalah < 21 cm, sedangkan jumlah sabun cuci cair yang dikeluarkan sebanyak 0,692 ml dan hand sanitizer sebanyak 0,814 ml. Setelah sensor mendeteksi keberadaan tangan, mesin akan menegeluarkan suara instruksi yang akan memandu penggunaan alat.

Abstract

Batteries are electrochemical devices as a source of DC voltage that is quite reliable and has high stability, so that the 110 Vdc Battery has a very important role at the substation (GI) to operate the driving motors at the voltage breaker (PMT), disconecting switch (PMS), supply PLC and telecommunication equipment in the SCADA system, as well as protection relays. If the 110 Vdc battery does not work properly, it can result in a major interference with the GI. So to help optimize battery maintenance, it needs an indication tool so that the battery can last a long time and can prevent damage to the battery prematurely. In this study, a voltage drop monitoring and detection system will be designed on 110 Vdc battery cells. The data will be forwarded to the database via the NodeMCU device to be sent to the Telegram application on the smartphone. The test was carried out by compiling 80 battery cells with a voltage of 1.5 volts in series to produce a voltage of 110 Vdc. Test results of the accuracy level of voltage readings achieved an average accuracy of 99.58% with an average difference of 0.42% while the test results of sending voltage data for each group were successfully carried out with excellent response and were able to display data / information on voltage values and conditions in telegram applications.

Abstract

Electricity plays a very important role in everyday life. Most human activities are related to the use of electrical energy, including in the Campus environment. Technological advances have resulted in an increase in the consumption of electrical energy and this has resulted in reduced reserves of fossil energy sources as a result of being used up and causing emissions that can affect the global climate. The energy transition from the use of fossil energy to new and renewable energy is one solution to overcome this. Solar Power Plant (PLTS) is an alternative energy solution that is environmentally friendly that can be developed on campus. This is also supported by Indonesia's geographical location which has a very high intensity of sunlight. In this study, an analysis of the potential of electrical energy generated at Universitas Muhammadiyah Parepare Building was carried out. The research was conducted by measuring the surface voltage and temperature of solar panels for 20 days. The test was carried out for 7 hours from 10.00 WITA to 16.00 WITA. Voltage and temperature measurements were carried out in 1 hour intervals. The test results show that the average voltage value generated by solar panels is 21.31 volts. The highest average voltage value was generated at 13.00 WITA, which was 21.82 volts with an average surface temperature of 37.79 oC

Abstract

The problem of plastic waste that is not handled and managed optimally can cause environmental damage. This study aims to test the compressive strength and water absorption value of paving blocks made of plastic which are designed using a mixed variation of V50-50 (50% sand, 50% plastic), V25-75 (25% sand, 75% plastic) and V0-100 (0% sand, 100% plastic) of the total proportion of the paving block mix. The method is carried out by melting PP (Polypropylene) mineral glass plastic, mixed with sand based on variations, printed according to the size of the paving block and used as a test sample in the form of a dice. The average compressive strength test results show that the sample with the code V25-75 has a relatively higher compressive strength value than V50-50 and V0-100. The average compressive strength value of the sample with code V25-75 is 11.53 MPa, followed by code V50-50 of 9.63 MPa, and the lowest is coded V0-100 of 3.70 MPa. The compressive strength value is influenced by the optimal percentage between sand and plastic, plastic serves as a binder for sand in a mixture of paving blocks. The percentage of water absorption value will continue to decrease along with the addition of plastic waste in the paving block mixture, V50-50 is 1.44, V25-75 is 0.88 and V0-100 is 0.16. This research is expected to be applied by the community to make paving block products, so that it can reduce the amount of plastic waste globally.
