Abstract

A Tsunami is a series of massive oceanic waves resulting from profound tectonic activities in the seabed. The disaster's devastating effect makes fast information delivery during a tsunami crucial in minimizing losses. For this reason, Tsunami warning systems need to be supported by a rapid detection technology. In recent years, radar has been implemented as a tsunami detector due to its sensitivity to oceanic waves. An array antenna using advanced microstrip technology, as the main component of a radar system, can fulfill the requirement for tsunami rapid detection. This paper presents the work that we conducted to develop a tsunami detection antenna using the array approach to improve gain and optimize radiation patterns. We designed a patch antenna with 12 mm in length and 21 mm in width and performed some simulations to obtain the antenna parameters such as gain, bandwidth, and optimal radiation patterns. As the results of our investigation, we determined the resonance frequency to be 5.4 GHz. The study produced a gain of 9.07 dB through simulations on an antenna that resonates at a frequency that meets the antenna work criteria, which include a loss of -26.69 dB, a VSWR of 1.09, and an HPBW (Half Power Beamwith) of 17.3°. Those values indicate that the antenna designed for tsunami detector applications functions correctly.

Abstract

ABSTRAKKarakterisasi untuk memisahkan mutu-mutu yang berbeda dalam aplikasi industri dapat dipenuhi dengan menggunakan alat dengan kemampuan yang terbatas. Teknik sortir memanfaatkan sistem papan evaluasi Eval AD5933 EBZ berakurasi 0,5% dilakukan terhadap pisang kepok (musa spp) hasil perkebunan di Pulau Enggano, Provinsi Bengkulu. Sistem dinyalakan dengan sambungan listrik bertegangan 2,7 V – 5,5 V mengeksitasi gelombang dari frekuensi 4000 Hz sampai 100.000 Hz kepada tiga sampel, masing-masing tiga kali sapuan. Tanpa ada modifikasi yang diberikan, sistem mampu membedakan impedansi musa spp antara jenis-jenis mutu mentah, mengkal dan masak melalui diagram Argand yang digambar dari data impedansi masing-masing. Diagram Argand yang dihasilkan menunjukkan jenis mutu masak dari musa spp lebih besar (dalam Ohm) dari jenisj-jenis mutu di bawahnya. Sistem ini dapat membantu industri pembuatan tepung pisang yang memerlukan pemilahan jenis bahan baku bermutu tertentu. Kata kunci: sortir, mutu, buah pisang kepok, impedansi ABSTRACTCharacterization to sortir different qualities in industrial applications can be fulfilled by using a tool with limited capability. Sorting technique using a 0.5% accuracy Eval AD5933 EBZ evaluation board system has been carried out on kepok banana (musa spp) from the plantation of Enggano Island, Bengkulu province. The system powered by a 2.7 V – 5.5 V DC low-voltage excited waves from 4000 Hz to 100,000 Hz frequencies to three samples, three sweeps of each. Without any modification, the system has been able to segregate different quality types of unripe, almost ripe and ripe from their Argand diagram drawn from their impedance data. The Argand diagram characterizes that the quality type of banana ripe is more expanded (in Ohm) than the other quality types of below. The system is applicable for a banana flour manufacturing industry that requires the sorting of certain types of quality raw materials.Keywords: sorting, quality, musa banana, impedance

Abstract

ABSTRAKBagi orang tua masalah kesehatan buah hati merupakan suatu hal yang sangat penting. Terlebih lagi bagi orang tua yang kurang beruntung melahirkan bayi dalam keadaan kurang sehat atau prematur menurut dokter, sehingga diperlukan perawatan menggunakan inkubator. Inkubator bayi adalah sebuah wadah tertutup yang kehangatan lingkungannya dapat diatur dengan cara memanaskan udara dengan suhu tertentu, yang berfungsi untuk menghangatkan bayi. Thingspeak adalah platform open source Internet of Things (IoT) aplikasi dan API untuk menyimpan dan mengambil data dari hal menggunakan protokol HTTP melalui Internet atau melalui Local Area Network. ThingSpeak memungkinkan pembuatan aplikasi sensor logging, aplikasi lokasi pelacakan, dan jaringan sosial. Berdasarkan perancangan yang dilakukan untuk penerapan sistem monitoring inkubator bayi prematur secara real time dengan menggunakan android tidak berjalan sesuai dengan yang diinginkan, karena memiliki delay waktu sebesar 10-15 detik. Pengaplikasian android sebagai sistem monitoring jarak jauh menggunakan kamera dilakukan dengan aplikasi GoPLus Cam. Aplikasi GoPlus Cam android dan kamera memiliki jarak koneksi maksimum yaitu jarak 15 m. Pengaplikasian android sebagai tampilan output suhu, detak jantung dan berat badan ditampilkan menggunakan aplikasi thingshow. Aplikasi thingshow menampilkan pembacaan data suhu dan detak jantung dalam bentuk grafik sedangkan pembacaan berat badan ditampilkan dalam bentuk angka dan berhasil ditampilkan pada android.Kata Kunci : Monitoring Inkubator Bayi, Thingspeak, NodeMCU ESP8266

Abstract

AbstractDuring the distribution process there will be a loss of some of the energy that is channeled. This phenomenon is known as losses. This is caused by technical and non-technical factors. In the  State Electricity Service (PLN) system, distribution losses or energy losses is calculated by measuring the difference between kWh produced and kWh sell. This kWh difference is the electrical energy lost during the starting process from the generation or secondary side of the Substation to customers’ APP. Cumulatively, the amount of kWh at all base sources is 73,769.524 kWh while the distribution loss that occurs in JTM is 5,835.008 or 7.91%. One way to overcome and minimize distribution losses in the 20 kV Procurement Service Unit (ULP) of Lima Puluh distribution system is to analyze the distribution network system, add new feeders and break the load on the electrical system. The simple branch exchange method is used to separate the network load, which is done by adding a switch by turning the on or off channel and searching for the configuration that produces the smallest power loss and calculating the power loss based on the network load. Based on the simulation results using the ETAP 12.6 software, the results of the energy loss of Procurement Service Unit (ULP) of Lima Puluh is 5,864,112 kWh then decreased after load separation of 4,341,348 kWh. The value of power loss before load separation is 1,955 kW and a decrease in power loss after load separation is 1,484.5 kW. The investment cost incurred for the construction of a new feeder is RP. 22,000,000,000,- with a payback of 9.9 years.  Keywords: Feeder, Power Loss, Energy Loss, ETAP 12.6.

Abstract

The use of electricity has now become a primary need for people who are used for activities as an energy source such as: lights, air conditioners, water pumps, washing machines, TVs, etc. and the longer the need for electrical energy in Indonesia is increasing while power plants are constantly increasing, this forces the government to continue to build power plants to meet the needs of electrical energy in the community. Of course, the construction of this power plant uses very large costs and various obstacles, one of the obstacles is that fuel that used to be a power plant used a lot of oil, now switches to gas and coal to reduce high electricity production costs. The research method that will be carried out is by feeding the generator output back into a rotor drive energy source so that there is a continuous circulation of energy so that the generator output can be charged according to the remaining power capacity fed by the generator. Based on the test results, results were obtained using a 25 Watt DC motor when the input voltage was 12 Volts the power generated on the motor was 13.8 Watts with a motor speed of 768 rpm. Testing on an 800 Watt generator obtained a maximum rpm result of 764 and a vout of 13.8 volts. the highest input voltage (Vin) obtained was 10.06 volts, the output voltage (Vout) was 3.9 volts, and the power produced was 41.34 Watts. The prototype design that was tested produced energy even though the results were still not significant.
