Abstract

Electricity, as a very important source of energy, was distributed to customers in the amount of 245518.17 GWh in 2019, and 42.25% of customers were households. The high consumption of electricity needs to be kept in mind. It is necessary to have a good and intelligent energy efficiency system. Nowadays, Internet of Things (IoT) technology is being widely used. The electricity monitoring system and prediction of the use of electrical energy in real time based on technology can be one solution to the problem of electrical energy efficiency. For this reason, the Monitoring System for household electricity use using an Internet of Things-based website is expected to increase user awareness and make electrical energy efficient in household groups. This study designs Internet of Things (IoT) technology for a smart monitoring system in everyday electricity use. The research method is experimental with a quantitative approach. This study tries Firebase as an IoT platform with NodeMCU ESP-32 as the microcontroller. The sensor used to detect all electrical parameters is PZEM 004T V3. Monitoring data in real time can be accessed via a web browser. The system as a whole system works well, in accordance with the desired work design. The average value of error reading energy is 2% or a difference of 0.01 kWh every day, as well as latency testing with an average delay of 21.5 ms, with 64 Byte data testing with a timeout of 1000 ms, 0.2% packet loss percentage of 548 data

Abstract

Hal terpenting pada machine learning adalah fitur ekstraksi dari sebuah data mentah. Pada jurnal ini akan dijelaskan mengenai Implementasi Machine Learning untuk identifikasi orang batuk / bersin. Tujuan utama penelitian ini adalah bagaimana mengklasifikasi suara bersin dan batuk pada situasi yang sulit seperti noise yang terdapat pada data mentah. Pekembangan kecerdasan buatan yang cukup pesat terutama pada klasifikasi suara menggunakan machine learning dapat membantu untuk membedakan batuk dan bersin berdasarkan suara. Dalam tugas akhir ini, algoritma Long Short Term Memory (LSTM) digunakan karena algoritma ini mampu mengklasifikasikan pola suara dari suatu data. Untuk menghasilkan program pendeteksi batuk penulis membuat 3 program utama yaitu Pre-Processing, Training, dan Prediction. Melalui metode yang digunakan, Implementasi Machine Learning untuk identifikasi orang batuk / bersin mampu mencapai nilai rata-rata akurasi 68,52%, presisi 88,10% dan recall 62,03%.

Abstract

Kebutuhan akan sumber tenaga listrik alternatif sangat dibutuhkan ketika cadangan bahan bakar minyak dunia semakin menipis. Dalam upaya tersebut maka dibutuhkanlah sumber energi yang tidak terbatas seperti tenaga surya. Faktor-faktor yang mempengaruhi optimal kinerja dari suatu panel surya adalah pengaruh suhu, shadding effect, dan bahan pembuat sel surya itu sendiri. Panel sel surya ini harus dalam kondisi optimal setiap saatnya. Karena panel surya disimpan pada rooftop maka panel ini rentan terkena shadding effect. Penelitian ini bertujuan sebagai acuan serta untuk menghilangkan shadding effect pada panel surya secara otomatis. Metode penelitian yang digunakan yaitu identifikasi masalah, observasi lapangan, perencanaan konsep, diagram alir serta skematik perancangan meliputi perancangan pyranometer dan solar cell, perancangan water pump, perancangan panel surya, perancangan motor DC, perancangan RTC. Hasil pengujian menunjukan bahwa, alat pembersih alat pembersih ini dapat lebih memaksimalkan penyerapan yang dimana didapat nilai total daya yang dihasilkan sebelum pembersihan sebesar 162,93W dan sesudah dibersihkan naik menjadi 180,69W. Daya yang diperlukan untuk melakukan pembersihan jika wiper naik sebesar 21,55W dan jika wiper turun sebesar 18,67W. hasil ini pun dapat berubah berdasarkan set point yang digunakan hasil tersebut menggunakan perbandingan 15 w/m2.

Abstract

Palm sugar is a food commodity with good economic value compared to the production of palm sugar in the form of bulk blocks, especially if it can meet export standards. One of the production centers for ant palm sugar is in Buni Kasih Village, Cupunegara Village, Cisalak District, Subang Regency, West Java. To produce palm sugar, several machines are needed in the process, including evaporation, crystallization, roasting, grinding and sifting. One of the problems that occur in the production process is milling. The existing machine always produces a process of melting palm sugar every five minutes, the process is carried out so that it must always be cleaned and takes quite a long time, thereby reducing the productivity of the machine which is quite significant. There are two possible causes for the melting, namely engine construction errors or engine speed that is too high around 2200 rpm. The engine modification process was carried out by replacing the gasoline engine drive with high rpm to an electric motor with a rotation of 1400 rpm along with modifications to the mount. Setting the reduction of engine speed is done by using a pulley-belt system. Tests were carried out on engine rotation between 500 rpm to 1000 rpm. Optimal rotation is obtained at 900 rpm where 90% of the powdered sugar produced by the mill is successfully sieved to be ready for packaging, while 10% is re-milled. At 1000 rpm the resulting powdered sugar can reach 95%, but the machine must be cleaned every hour so that the sugar does not start to melt.

Abstract

The availability of data loggers as data acquisition is still limited to sensor levels and the data loggers have not been produced in Indonesia. This makes it difficult for monitors to obtain data such as water pressure and water discharge data. The solution to this problem is to reduce the import cost of purchasing data loggers from abroad by developing data loggers that are able to take data on water level, water pressure. This study aims to determine how the design and performance of data logger system substitution products flow and water pressure using LoRa WAN communication. The test results show that the Water Flow and Pressure Data logger System functions according to the design that has been made with error readings from the itron cyble sensor of ?? and a pressure sensor reading error of 20.66%. The Packet Loss value of sending data from the data logger device is directly proportional to the distance where the smallest packet loss value is 13% at a distance of 50m and 80% at a distance of 2800m.

Abstract

Pendidikan vokasi SMK menghadapi kesenjangan kompetensi pada teknologi robotika manufaktur. Artikel ini bertujuan mengevaluasi intervensi pembelajaran berbasis collaborative robot (cobot) melalui pengenalan dan praktik terintegrasi. Program mengembangkan teaching aid cobot terintegrasi  PLC dan HMI Berbasis IoT serta menerapkan pelatihan intensif dua hari (16 jam) kepada 34 peserta (guru dan siswa) di SMK mitra. Metode mencakup desain pengembangan perangkat, pelatihan berbasis proyek, pendampingan daring, serta evaluasi kuantitatif (pre-test dan post-test) dan umpan balik kuesioner; sebagian peserta mengikuti asesmen sertifikasi pihak ketiga. Hasil menunjukkan peningkatan kompetensi yang signifikan (rata-rata skor post-test melampaui pre-test), dengan sikap dan antusiasme peserta pada kategori tinggi, meski penguasaan teknis masih membutuhkan penguatan praktik. Kebaruan program terletak pada integrasi lowcost teaching aid cobot yang mereplikasi ekosistem otomasi industri (cobot, PLC, HMI) dan skema kemitraan antara SMK, perguruan tinggi, dan industri yang memungkinkan adopsi kurikulum praktik secara berkelanjutan. Disimpulkan bahwa pendekatan ini efektif meningkatkan kompetensi manufaktur berbasis robotik dan kesiapan kerja siswa, serta layak direplikasi dengan penyesuaian konteks dan alokasi waktu praktik tambahan pada aspek teknis.
