Flooding is a natural phenomenon caused by water flowing in a volume that exceeds the capacity of the media holding it. The floods affect various human activities. In addition, floods also cause material losses and other related fatalities. To overcome this problem, a flood warning system based on Arduino microcontroller technology and WeMos D1 Mini ESP8266 was designed. The data measured are water level, water velocity, and rainfall. Furthermore, the three data will be combined with Fuzzy logic to make decisions. The output of the system is in the form of a remote command signal that will activate the alarm sound and indicator lights to give a warning to the public about the potential flooding that will occur. The test results show that the measured data has become sufficient information for the microcontroller to generate the corresponding indicator lights and alarm sounds.

Kegiatan Keagamaan di masjid selalu ditandai dengan pemutaran audio MP3, misalkan sesaat sebelum adzan dikumandangkan, umumnya masjid di daerah Sumbawa akan memutar beberapa file MP3 terlebih dahulu baru setelahnya azan dikumandangkan. Merubah audio MP3 dari satu sesi pemutaran ke sesi pemutaran lainya dilakukan dengan cara mengganti flash drive yang telah diisi dengan file MP3 tertentu. Kondisi ini kurang efisien dirasakan oleh pengurus masjid Raudhatul jannah Desa Gontar, Kec. Alas Barat, Sumbawa. Sehingga dari kondisi tersebut terbersit suatu ide untuk membuat suatu perangkat pemutar audio yang ringkas agar setiap pergantian MP3 yang ingin diputar tidak perlu mengganti flash drive. Sistem pemutar audio ini dibuat dengan menggunakan teknologi Arduino yang dihubungkan ke suatu perangkat pemutar MP3 yaitu DFPlayer mini. Adapun beberapa tahapan yang dikerjakan dalam membuat perangkat ini yaitu: mendesain PCB sebagai tempat perangkat elektronik pendukung disusun, memprogram Arduino agar dapat berkomunikasi dengan perangkat DFPlayer mini,  dan terakhir melakukan penyusunan komponen-komponen pendukung seperti keypad dan power unit serta melakukan pengujian. Perangkat ini telah berhasil dibuat dan telah dipasangkan di masjid raudhatul jannah, gambaran singkat dari perangkat ini yaitu: memiliki keypad yang berguna untuk memilih file MP3 yang akan diputar, memiliki perangkat Jack audio pada bagian bawah untuk berkomunikasi dengan perangkat audio utama.

One of the service provided by the Hospital is by providing fast service, so give satisfaction to secoety. Service provided by the Hospital in increasing customer satisfactions whit using technology the SIMRS application. Contitution Republic of Indonesian No. 44 year 2019 about Hospital in chapter 1 paragraph 3 every Hospital must organize SIMRS application. The purpose of this study was to determine the effect of the level of knowledge and motivation of nurses on the use of the SIMRS application at RSUD Sumbawa. Population in this research were 149 respondents. The sampling technique in quantitative research with a sample of 109 respondent and the sampling technique in qualitative research with a sample of 10 respondent. The method on this research is a mix method with cross sectional and generic quality approach. The results of the study obtained a p-value 0,001 < 0,05% which means that there is an effect on level of knowledge nurses on the use of  the SIMRS application and there is an influence on the motivation of nurses in using the SIMRS application at RSUD Sumbawa.

A water quality monitoring system in hydroponics with a Total Dissolved Solid Sensor (TDS) equipped with the Arduino UNO microcontroller has been developed.  The TDS SEN0244 sensor read the water sensitivity, which will display the value of the reading on the LCD. Furthermore, if the output is less than 2.30 Volts or 1000 ppm, the buzzer will sound once, and the dosing pump will rotate to automatically add nutrients A and B. The buzzer will sound twice if the output is more than 2.40 Volts or 1200 ppm. When reading the sensitivity of water (well water) with a water value of 400 ppm, the relevant results were obtained, namely, 1000 - 1200 ppm when 4 - 5 mL of the nutrient solution was added to water with a capacity of fewer than 6 liters. The appropriate value was obtained when testing the TDS sensor on several water samples. However, in the salt and soapy water samples, the voltage value reading was unstable or experienced an error. Implementing this system is expected to make it easier for the community, especially farmers, to cultivate hydroponic plants.

This study aims to determine the magnitude of the fluctuating load factor on the efficiency and loss of life of the 6kV/70kV transformer and to determine the optimal load in order to obtain the best efficiency and minimize loss of life. The method used in this study is a quantitative research method. The results showed that the highest efficiency of PLTU Unit 1 was at 93.3% with an output power of 5.8 MW and an input power of 6.21 MW, while the lowest was at 83.9% with an output power of 5.5 MW and a power 6.55 MW input. The highest efficiency of PLTU Unit 2 is at 95.7% with an output power of 5.5 MW and an input power of 5.75 MW, while the lowest is at 61.03% with an output power of 3.3 MW and an input power of 5.41. MW. Meanwhile, the transformer life for Unit 1 PLTU Sumbawa Barat is 0.0469 hours/day with an average load of 5.8 MW, while for Unit 2 it is 0.0311 hours/day with an average load of 5.2 MW. The size of the loss of life of the transformer depends on the given load, the greater the load, the greater the loss of life. In this case, the load for Unit 1 is higher than for Unit 2, so it can be seen that the life loss of the Unit 2 transformer is smaller. While the optimal load on the PLTU is in the position of 80-85% of its capacity. The results of this study are expected to be a material consideration for the Sumbawa power plant to better distribute and optimize the load so that there is no imbalance between the transformer capacity and the power produced and perform routine transformer maintenance to reduce losses that occur.
