Elektrostimulator combined in acupunture therapy to provide the stimulation of electric energy at the point of the meridians of the body. Granting the power to create a balance of energy (chi) in the body. In administering the energy must pay attention to the voltage waveform, intensity, frequency and timing of stimuli. The purpose of this research is to change the system tools from analog into digital by changing the settings of the timer and frequency using the keypad that is controlled using the Microcontroller ATMega16. Specifications of the simulation tool elektrostimulator acupunture designed include the frequency setting of 5-100Hz, setting the intensity of a voltage 0 timer setting until 25Vac 60 minutes and has a spike waveform mode continou and electrodes used floating types. The test result show that simulated acupunture elektrostimulator tool result obtained in accordance with the compliance with the specifications but there is little the percentage error of frequency deviation i.e. 0.47% deviation of the timer of 0.29%, intensity of the voltage deviation of 0.073 % and waveform was nearing the same against his theory.
INTISARIPada naskah ini akan dilakukan analisis nilai tegangan dan arus pada Alat Kontrol Intensitas Lampu Jalan Otomatis Tenaga Surya. Data tersebut diperoleh dari hasil pengujian alat terssebut dengan waktu/jam yang berbeda-beda untuk mengetahui efektivitas cahaya matahari dalam mengisi daya solar panel. Alat tersebut dibuat agar hemat energi dan sebagai energi alternatif. Sumber utama dari penerangan ini adalah dari energi matahari yang dikonversi oleh panel surya menjadi listrik, dan baterai atau aki berfungsi sebagai penyimpan energi listrik yang akan menyalakan lampu pada malam hari. Oleh sebab itu, apabila listrik PLN mengalami gangguan atau mati listrik maka penerangan jalan ini tidak terpengaruh.Dari alat di atas, diperoleh hasil pengujian untuk variable tegangan arus. Selanjutnya akan dianalisis pengaruh waktu/jam terhadap pengambilan data nilai tegangan dan arus. Pada data waktu pengisian panel surya, rata-rata tegangan dari solar cell sama yaitu 19,54 volt dan median (nilai tengah) sebesar 20 volt serta nilai rerata arus sebesar 0,81 A dan median sebesar 0,8 A. Semakin siang maka arus yang masuk ke baterai semakin besar karena energi dari sinar matahari berada pada puncaknya yaitu pada jam 11:00 sampai 13:00, kemudian semakin sore maka arus yang masuk semakin kecil karena sinar matahari yang diterima solar cell sudah tidak optimal.Kata kunci— solar panel, tegangan, arus, energi matahari ABSTRACTIn this paper, an analysis of the value of voltage and current will be carried out on the Intensity Control Tool for Automatic Solar Street Lights. The data was obtained from the results of testing the tool with different times/hours to determine the effectiveness of sunlight in charging solar panels. The tool is made to save energy and as an alternative energy. The main source of this lighting is from solar energy which is converted by solar panels into electricity, and the battery or battery serves as a store of electrical energy that will turn on the lights at night. Therefore, if the PLN electricity is interrupted or there is a power failure, the street lighting will not be affected.From the above tool, the test results are obtained for the current voltage variable. Furthermore, it will be analyzed the effect of time/hour on data retrieval of voltage and current values. In the solar panel charging time data, the average voltage from the solar cell is the same, namely 19.54 volts and the median (middle value) is 20 volts and the average current value is 0.81 A and the median is 0.8 A. The amount that goes into the battery is getting bigger because the energy from sunlight is at its peak at 11:00 to 13:00, then later in the afternoon, the incoming current gets smaller because the sunlight received by the solar cell is not optimal.Kata kunci— solar panels, voltage, current, solar energy
Media informasi kesehatan masyarakat ini merupakan sistem pengolahan data dan informasi kesehatan di semua tingkat pemerintahan secara sistematis dan terpadu untuk mendukung manajemen kesehatan dalam rangka peningkatan pelayanan kesehatan kepada masyarakat. Media informasi ini terdiri dari data, manusia dan proses serta kombinasi perangkat keras, perangkat lunak dan teknologi informasi. Penggunaan media informasi ini terdiri dari 3 tahap yaitu pemasukan data, pemrosesan dan pengeluaran informasi. Media informasi kesehatan ini menggunakan metode semi-blocking atau harus sesuai dengan kata kunci yang ada pada database. Berdasarkan hasil perancangan disediakan 3 jenis informasi yaitu: gejala, pencegahan, dan pengobatan dari suatu penyakit yang umum dan berpotensi mengganggu kesehatan masyarakat. Jenis penyakit yang bisa dikenali oleh sistem mampu mencapai hingga 1000 jenis, sehingga akan membantu masyarakat mendapatkan informasi untuk mendukung keputusan tindakan yang akan dilakukan saat darurat secara cepat, kapan saja dan dimana saja sedangkan waktu respon rata-rata SMS sekitarnya 6 detik tergantung kualitas sinyal dan trafic data dari suatu provider oleh pengguna.
Today's technological developments have largely replaced conventional ones. One example is the RFID system. Patient Card is an identification in the form of patient data documents in conventional hospitals. Therefore, with this RFID system, it can contain a security control system both in terms of administration and information technology based on a database in the Hospital. The data is stored in the Patient Card based on digital data. Utilization of digital data-based patient cards to speed up patient services in the registration process during treatment, and reduce queue times when the data identification process is carried out by the patient registration department, as well as the efficiency of human resources. The process of designing tools by initializing the use of tool components. The data processing is carried out by Arduino Nano to read RFID and serial communication to communicate with Arduino UNO as a graphic LCD display. The Arduino Uno processor used detects the card. With the validation of the card, the patient can continue the examination process to the desired poly and exit in the form of a printed queue number according to the destination poly.
The need for electricity in Indonesia and throughout the world is increasing, while most of the energy sources for electricity generation are still using fossil fuels such as oil, natural gas and coal. Fossil energy has a high level of pollution which is the cause of global warming, it is necessary to replace fossil energy that is environmentally friendly, namely renewable energy. The construction of power plants such as micro hydro power plants (PLTMh) which are located in irrigation canals or rivers with relatively small water discharge will result in low wheel rotation. The waterwheel rotation in this PLTMh system has a low rotating speed of around 200 rpm, and has a low torque or no cogging torque effect. Based on the needs in the field, a permanent Neodymium Type (NdFeB) Permanent Magnet Axial Flux Generator is built, which is specifically designed for low speeds of 200 rpm and has no cogging torque or low rotational torque effects. And it is hoped that the design of this generator can be used according to the needs of PLTMH. The results obtained in this study are, the generator can produce a voltage at a rotational speed of 200 Rpm and a frequency of 50 Hz is 100 VAC.
