Banyak penelitian memanfaatkan energi RF yang dihasilkan oleh perangkat Wi-Fi sebagai salah satu sumber energi alternatif. Akan tetapi pengaruh pemanfaatan energi RF yang bersumber dari Wi-Fi tidak banyak yang mengulas. Pada penelitian ini dibahas pengaruh penggunaan node harvester yang memanfaatkan energi RF yang dihasilkan oleh perangkat Wi-Fi terhadap kinerja jaringan Wi-Fi tersebut. Pada penelitian ini dilihat pengaruh jarak 4 node harvester terhadap kinerja jaringan Wi-Fi yang terdiri dari 1 mikrotik routerboard, 4 laptop. Parameter yang diujikan dimulai dari tegangan pada harvester, nilai throughput, delay, packet loss dan power density. Dari hasil penelitian kapasitor 470 µF menghasilkan tegangan terbesar dengan nilai ±0.4V. Nilai tegangan pada harvester akan semakin tinggi ketika didekatkan dengan Wi-Fi dan bernilai 0 di jarak ±15 m dari Wi-Fi. Hasil pengujian memperlihatkan nilai throughput yang terus menurun seiring penambahan jarak harvester ke Wi-Fi penurunan disebabkan oleh best effort pada jaringan. Sedangkan nilai delay yang didapatkan tidak murni terpengaruh oleh penggunaan harvester dan nilai packet loss didapat 0 % . Power density mengalami penurunan nilai daya ketika harvester semakin dekat jaraknya dengan Wi-Fi dan selisih nilai daya ±2 dBm disetiap perpindahan jarak yang ditetapkan.","PeriodicalId":308479,"journal":{"name":"Jurnal Elektro dan Mesin Terapan (ELEMENTER)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121055508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Akibat terbatasnya ketajaman pendengaran perkembangan bahasa dan komunikasi menjadi terhambat. Oleh karena itu, dalam berkomunikasi dan berinteraksi secara social, penyandang tunarungu menggunakan bahasa isyarat. Bahasa Isyarat yang sering digunakan di Indonesia adalah menggunakan Sistem Bahasa Isyarat Indonesia (SIBI). Sistem Bahasa Isyarat Indonesia (SIBI) adalah sistem bahasa yang dikembangkan langsung oleh para penyandang tunarungu atau tunawicara. Meskipun telah ditemukan bahasa isyarat bagi penyandang tunarungu dan tunawicara, bahasa isyarat masih memiliki kekurangan ketika digunakan kepada orang yang belum pernah belajar bahasa isyarat sebelumnya. Untuk menjawab permasalahan tersebut, maka dilakukan pengembangkan sebuah perangkat berupa sarung tangan yang mampu menerjemahkan bahasa isyarat dengan keluaran berupa suara. Perangkat yang dimaksud adalah berupa sarung tangan yang menggunakan sepuluh buah sensor flex yang di control menggunakan mikrokontroller sebagai pengolahan data. Hasil klasifikasi akan diterjemahkan berupa keluaran suara dari perangkat.

An unreliable protection system has the impact of economic losses, this is the basis for engineers to conduct research on the optimization of protection coordination in the electric power system. This study aims to ensure that the protection system can run properly in the event of a short circuit fault in the system. In addition, this research is to facilitate engineers in the calculation of the Directional Overcurrent Relay (DOCR) coordination study. In contrast to previous studies, this research implements a hybrid algorithm method on a real electrical system by considering the generator operating scheme. Due to the generator operating conditions that are always changing, it affect DOCR working time. To overcome these problems, it is necessary to set an optimal DOCR using the meta-heuristic method. This is the basis for researchers to conduct research on optimization of protection coordination settings. Each meta-heuristic method such as Differential Evolution Algorithm and Particle Swarm Optimization has its own advantages and disadvantages in the process of searching the optimization. Therefore, this research implements a hybrid strategy of Differential Evolution Algorithm – Particle Swarm Optimization (DE-PSO) to get the DOCR Time Dial Setting (TDS) value. From the results of the study, it can be concluded that using a hybrid algorithm is 83% more efficient than the non-hybrid method.","PeriodicalId":308479,"journal":{"name":"Jurnal Elektro dan Mesin Terapan (ELEMENTER)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121884794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research develops a real-time fuel tank volume measurement system. This system sends measurement data to server if the system is connected to internet network. This system uses ultrasonic sensors to measure level of the fuel surface and uses NodeMCU ESP8266 as a controller and delivery via Wi-Fi. The ultrasonic sensor is directed into the buried tank in a position perpendicular to the surface of the liquid. The distance measurement results are obtained by calculating the transmitting time of the transmitter until it is received back by the receiver. Then, the calculation of the tank volume obtained from the distance calculation results is inserted into the equation for the area of the tank circle which is processed using the NodeMCU ESP8266 as the main controller. The volume measurement results are sent by the NodeMCU ESP8266 to webserver to be displayed on website and saved to database. The results of measuring the volume of the tank are quite accurate but there is still an average error of about 1.3. This is influenced by the slight bend in the tank.","PeriodicalId":308479,"journal":{"name":"Jurnal Elektro dan Mesin Terapan (ELEMENTER)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130226018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Saat ini, penggunaan komunikasi nirkabel untuk mendukung proses pembelajaran di ruang perkuliahan telah banyak diaplikasikan. Namun, rugi-rugi lintasan gelombang radio di ruang perkuliahan mengalami peningkatan jika gelombang radio berpropagasi dari luar gedung. Hal tersebut disebabkan gelombang radio mengalami rugi-rugi lintasan secara dua tahap, yaitu di luar gedung dan di dalam gedung. Berdasarkan hal tersebut, penelitian ini bertujuan mengukur dan menganalisis pengaruh koridor di gedung kampus terhadap rugi-rugi lintasan gelombang radio di ruang perkuliahan. Sebuah antena pemancar di luar gedung kampus milik salah satu penyedia jasa layanan telekomunikasi digunakan pada penelitian ini. Selanjutnya metode drive test digunakan untuk mengukur rugi-rugi lintasan gelombang radio di ruang perkuliahan. Tiga model rugi-rugi lintasan yang kontemporer juga digunakan untuk memprediksi rugi-rugi lintasan gelombang radio. Ketiga model tersebut adalah Model Winner+, Model COST231, dan Model 3GPP. Berdasarkan hasil penelitian, diketahui bahwa koridor di dalam gedung mampu menurunkan rugi-rugi lintasan gelombang radio.
