Abstract

Kebutuhan energi listrik yang terus meningkat masih didominasi oleh penggunaan bahan bakar fosil yang tidak terbarukan. Sebagai alternatif, energi air menjadi pilihan yang ramah lingkungan dan potensial, terutama di Indonesia yang memiliki sumber daya air melimpah. Energi dari aliran air dimanfaatkan untuk menggerakkanaturbin dalam sistem PembangkitaListrik TenagaaMikrohidro (PLTMH). Salah satu komponen utama dalam sistem ini adalah turbin air. Dalam penelitian ini difokuskan pada pengaruh variasi bentuk turbin terhadap keluaran daya, khususnya pada bentuk turbin vortex, savonius, kaplan, dengan mempertimbangkan desain turbin sebagai faktor penting dalam menentukan efisiensi dan RPM turbin. Hasil dari pengukuran yang di lakukan diperoleh nilai tertinggi dengan bentuk turbin vortex dengan hasil rpm tertinggi sebesar 154,5 rpm, rpm generator 393 rpm, dan tegangan 8,4 V serta arus 0,25A.

Abstract

This study examines the use of Yagi antennas to extend the LoRa SX1278 transceiver's range, focusing on enhancing communication distance and reducing signal loss. LoRa, a low-power wireless technology, enables long-distance transmission ideal for sensor data, reaching up to 15 km in rural areas and 1-5 km in urban environments. By adjusting impedance, the Yagi antenna improves LoRa signal range and quality by focusing transmission directionally, reducing interference. The test results show that the yagi antenna has better coverage and signal strength than the spring antenna. Testing horizontal conditions with 3 different locations shows that antenna design greatly affects the transceiver of data. The Yagi antenna with modified impedance has the ability to transmit the farthest distance of 6250 meters. Horizontal testing with a fairly short distance is not too significant a difference in the rssi value of the two antennas, but in terms of reception category, the spring antenna is still not good. Test results show that the Yagi antenna significantly outperforms the spring antenna, maintaining better signal strength at longer distances due to its effective electromagnetic energy focus.

Abstract

Dewasa ini, virtualisasi dan cloud computing telah menjadi tren teknologi informasi khususnya untuk perusahaan skala enterprise. MetaROUTER merupakan implementasi virtualisasi pada RouterOS v3.21 keatas yang berjalan pada RouterBoard dengan platform MIPS-BE. Fokus penelitian ini adalah virtualisasi router berbasis MetaROUTER dimana antar virtual router tidak saling berhubungan dan memiliki fungsi yang berbeda. Fungsi dari masing-masing virtual router adalah manajemen bandwith dengan PCQ, proxy server dan hotspot yang teintegrasi dengan PCQ. Skenario pengujian meliputi empat aspek yakni independensi, performa, throughput dan security. Hasil pengujian menunjukkan bahwa penggunaan memori untuk tiap skenario pengujian pada virtual router relatif sama yakni tersisa 5.1MB untuk download, 5.8MB untuk browsing, dan 5.3MB untuk hotspot. Untuk CPU load, aktivitas download membutuhkan CPU paling banyak, yakni 13%. Untuk throughput, pada VR1 nilai TX berada pada nilai 1013Kbps sedangkan RX pada nilai 30Kbps, VR2 sebesar 122.435 KB/detik, dan VR3 sebesar 119.617KB/detik. Hasil pengujian security menunjukkan bahwa tiap virtual router tidak dapat mengirim paket ICMP ke router utama karena rule drop pada firewall.

Abstract

This research is proposed to answer two questions: Firstly, to find out the cause of fictitious orders experienced by Go-Jek drivers in the Go-food menu in Go-Jek app. Secondly, to know the legal protection of Go-Jek drivers who suffered losses due to a fictitious plane in the Go-food menu on the Go-Jek app. And the research is directed to educate the public the importance of Civil law which governs agreement in the life of society. This study uses socio-legal approach with a number of resource persons. The choice of approach to socio-legal does not mean disregarding doctrinal side support on the grounds that one of the aims of this study sees a set of positive norms in relation to Legal protection of Go-Jek drivers, including legal theory support with a view to verifying the implementation of law in practice (protection and responsible). This study concludes that, Transactions using Go-Jek access has so far caused legal consequences among others who is responsible for the losses experienced by drivers, whether the Go-Jek party is responsible for the losses experienced drivers, including what kind of legal protection obtained by the driver when suffering application losses by irresponsible consumers. The factors of the emergence of fictitious orders are the existence of competitions between the Go-Jek driver, Go-Jek verification system is still weak, and the existence of bad faith in someone. Partnership agreement between PT. Go-Jek and Go-Jek’s driver is a standard clause that created and provided without involving the Go-Jek drivers in which there is a clause of transfer of responsibility because of PT. Go-Jek as the Go-Jek application service manager will not be responsible if there is a loss caused by the use of Go-Jek application. The legal relations and responsibilities of the parties should be clearly stipulated in the partnership agreement between PT. Go-Jek Indonesia, and Partners are created based on mutual agreement and agreement between both parties. To minimize the losses experienced by Go-Jek drivers in service delivery for every use of consumer spending service must have a Go-Pay account, which expenditures can not be executed if the balance in the Go-Pay account is insufficient to make an expense transaction.
