Abstract

Makalah ini membahas rancang bangun sistem energy harvesting, yaitu suatu teknik pemanenan energi yang memanfaatkan sumber energi dari kebisingan yang dihasilkan mesin winder di sebuah pabrik pemintalan benang. Pemanenan energi menggunakan transducer berupa piezoelektrik array. Piezoelektrik array terdiri dari susunan seri dari 24 piezoelektrik yang ditempatkan pada osilator berbentuk cantilever beam. Osilatorterbuat dari bahan nilon dengan panjang yang disesuaikan dengan frekuensi suara bising mesin winder. Sistem yang dibangun diuji pada ruangan produksi pabrik pemintalan benang dengan tingkat kebisingan suara sebesar 95,8 dBA. Keluaran dari hasil rancang bangun tersebut mampu menghasilkan sinyal dengan nilai amplitudo maksimum sebesar 3,32 Vpp untuk frekuensi 50,42 Hz, dan daya maksimum sebesar 0,45 mili Watt pada daya terukur rata-rata sebesar 0,16 mW. Pengukuran tersebut dilakukan selama 1 jam, dan energi yang diperoleh sebesar 0,16 mWh. Dengan asumsi mesin beroperasi selama 10 jam per hari, energi yang dihasilkan dapat mencapai 1,6 mWh per hari. Dalam skala yang lebih besar, keluaran sistem energy harvesting yang diusulkan dalam penelitian ini dapat digunakan peralatan listrik berdaya rendah seperti pengisi baterai telepon seluler atau lampu penerangan darurat.

Abstract

Gedung Fakultas Psikologi Universitas Jenderal Achmad Yani (Unjani) merupakan gedung perkuliahan yang berada di lingkungan kampus Unjani dan belum memiliki instalasi sistem jaringan indoor. Kondisi tersebut menyebabkan level sinyal yang terukur di dalam gedung memiliki nilai RSRP lebih kecil dari -110 dBm. Level sinyal tersebut termasuk dalam kategori kualitas sinyal 4G yang kurang baik. Selain itu faktor lain yang menyebabkan pelemahan sinyal ialah material dan konstruksi bangunan tersebut. Oleh karena itu, agar user pada gedung tersebut dapat terlayani dengan baik, solusi yang dilakukan adalah melakukan perencanaan jaringan Indoor Building Coverage (IBC) 4G. Berdasarkan perhitungan coverage planning jumlah antena yang diperlukan dalam perencanaan sebanyak 14 antena yaitu lantai 1 dan 4 masing-masing sebanyak 3 antena, lantai 2 dan 3 masing-masing sebanyak 4 antena. Berdasarkan hasil simulasi pada software RPS diperoleh persentase nilai rata-rata nilai RSRP >-90 dBm sebesar 89,93 % dan persentase rata-rata nilai SINR >3 dB sebesar 87,95 %. Berdasarkan hasil simulasi tersebut didapatkan bahwa hasil perencanaan yang telah dibuat telah memenuhi standar operator dan dapat diterapkan untuk memperbaiki coverage dan meningkatkan level sinyal di Gedung Fakultas Psikologi Unjani.

Abstract

One of the problems with internet networks in rural areas is the difficulty of connecting cable-based internet because the distance is too far, wireless/wireless-based internet networks can be an alternative solution to these problems. A research analysis of the Power Link Budget calculation was carried out in planning the outdoor wireless internet network in the village. Kutanagara Garut. The test was carried out using the Power Link Budget calculation method and simulation using the Ubiquiti ISP Design Center application with a LiteAP GPS transmitter device and a NanoBeam 5AC receiver. Network planning is made using the Point to Point (PTP) system in the 5725 MHz frequency band to be precise at 5725 MHz Sub Band NII-3. The parameters tested are SOM (EIRP, margin signal), free space loss (FSL), Fresnel zone clearance (FZC), coverage area, signal strength obtained and internet speed capacity. The results of the calculations and configurations show that the EIRP value of the sender is 36 dBm, the EIRP of the receiver is 36 dBm, the maximum bandwidth is 20 MHz, Fresnel zone clearance is 3.4 m and the received signal strength is -49 dBm. These results have met the standards set by KOMINFO and a network design can be made. The results of the network simulation show that the internet network design has covered the entire area of Kutanagara Garut Village with an estimated signal obtained is -49 dBm, with a signal margin of 46.2 dB which already meets the standards of TIPHON with network classification included in the outstanding category (very good). Has a maximum internet capacity of 147 Mbps consisting of 74 Mbps download speed and 74 Mbps upload speed

Abstract

5G New Radio (NR) services can provide high data rates and low latency. The existence of 5G technology, especially in Indonesia, has been implemented by several cellular operators in the 2300 MHz and 1800 MHz frequencies. Therefore, a more detailed planning analysis is needed, especially in urban areas. In this study, planning for the 5G network needed in one of the urban areas in Cimahi City, West Java. This research was carried out for a frequency of 2300 MHz using the coverage planning analysis method. The propagation model used in this study is 3GPP TR38.900. Based on the analysis and calculations performed, obtained 26 sites for the area of ​​Cimahi City which has an area of ​​about 40.3 km². The location of the site is arranged based on the coverage conditions in the area and also based on the distribution of the 4G network that previously existed in the area, because the 5G planning used is the Non-Standalone 5G type. Based on the results of the coverage analysis carried out, the condition of the Synchronization Signal Reference Signal Received Power (SS-RSRP) signal level above -90 dBm reached 27.3% of the total area. This shows that the 5G network planning in this area can only cover an area of ​​up to a quarter of the total area.

Abstract

The use of internet networks in human life has become one of the needs in various fields, both offices, government agencies, schools, public services, and others. PT. Cilsy Fiolution Indonesia as one of the startups engaged in the field of information and technology education (Edu-Tech) is very active in the use of the internet, including content creation, uploading videos, office operations, programming, and others. With the limited bandwidth resources available at the office of PT Cilsy Fiolution Indonesia, and with a significant number of active users, it is not uncommon for uneven bandwidth distribution among employees who use internet access, causing problems in working. MikroTik Routerboard is a brand of router devices that has many features. By utilizing the queue tree feature on the MikroTik Router device, bandwidth settings at PT Cilsy Fiolution Indonesia can be based on the port and application protocols commonly used, including HTTP, HTTPS, ICMP, DNS, video streaming, and downloading several types of file extensions. This bandwidth management arrangement aims to equalize the distribution of bandwidth and provide good quality of service for all internet users in the office network of PT Cilsy Fiolution Indonesia.

Abstract

Selection of devices for IoT needs can be determined based on the range from the shortest to the furthest, and on the internet access or Wi-Fi availability, which can be considered in advance and adjusted to the needs. In line with this, a training was carried out at SMKN 1 Cimahi, involving several groups of experts in the Electrical Engineering familyto open insight and understanding regarding the needs of devices that can be used to build internet-based or IoT systems. This training also introduced several observation schemes with various platforms, that are available in both free and paid choices. The training activities were carried out for 16 hours face-to-face, and 16 hours of independent projects that consisted of 10 modules. Out of these activities, it is expected that the participants can improve their thinking skills and carry out system programming processes according to needs and readiness.
