Rugi daya dalam sistem distribusi daya listrik 3 phasa dipengaruhi oleh keseimbangan beban, penempatan trafo dan pemilihan kabel. Pada paper ini, akan dibahas tentang keseimbangan beban dalam mengurangi rugi daya listrik. Pembagian beban 3 phasa pada jaringan distribusi sekunder yang optimal digunakan Algoritma Genetika (GA). Posisi beban pada tiap bus dalam jaringan distribusi sekunder dikodekan dalam bilangan desimal dan disusun dalam satu kromosom. Proses optimasi dilaksanakan dengan operator genetika dan aliran daya 3 phasa. Pada hasil analisis diperoleh penurunan Rugi daya sebesar 5.3% .Kata kunci: Algoritma Genetika (GA), Rugi daya, Jaringan Distribusi Tegangan Rendah

The design of the solar power plant (PLTS) at the Antosari village wantilan is a research thataims to realize the use of new and renewable energy which is one of the solutions inovercoming electricity needs, saving fossil energy and assisting in the realization of GovernorRegulation 45/2019 concerning Bali Clean Energy. This study carried out the design andcalculations in the design of the PLTS Atap Antosari Village. The PLTS design is carried out bypaying attention to and taking into account the tilt angle of the Helioscope Software, designingthe placement of the solar panel modules, designing the inverter, configuring the circuit, takinginto account the number of batteries used, selecting the Battery Control Unit and calculating theprofit on investment. The results of the simulation on the helioscope software are the number ofsolar modules as many as 72 units, installed at an angle of 14.95o which can supply a batterywith a capacity of 500Ah. The simulation also determines the use of an inverter that uses a 4kWinverter which produces a power of 3.6 kWp. The ability of the installed solar module to flow acurrent of 97.56A so that the full charge condition is obtained for 6 hours. Research initialcapital of Rp. 201,400,000 with a return of Rp. 1,325,376, - per month, so that the financing forinstalling PLTS will return in 2034 (13 years)

The aim of this study is to help a company gas or chemical companies to determine the point of a gas leak. To find out the point of the gas leak, it is necessary to create a robot capable of exploring the underground passageway and has the ability to detect scent strength of gas, so that the point of the leak can be found .. One of the application of robotics technology in accordance with the conditions of underground passageways are a robot that has a combination of Wheeled Robot Arm Robot and 6WD. Due to the design of the robot can roam the surface conditions are not flat and has the ability to balance its body. The results achieved in this study is that the robot can detect the presence of butane gas use TGS2600 sensor. In addition, the transmission of information from the robot to use XBee interface software has been successfully carried out. So that the operator controls the robot can monitor the condition of the robot. Delivery of image information from the robot to the operator can be performed via the S-video channel then transferring images from the camera to the laptop.

Penggunaan etanol atau alkohol sebagai minuman sudah dikenal luas, banyak minuman beralkohol yang tidak memiliki izin, beredar di masyarakat. Maka tidak mengherankan keracunan akut maupun kronis akibat etanol sering terjadi. Menurut PER.MENKES No.86/1977, minuman beralkohol dibedakan menjadi 3 (tiga) golongan yaitu Golongan A dengan kadar alkohol 1-5% (misalnya bir), Golongan B dengan kadar alkohol 5-20% (misalnya anggur), dan Golongan C dengan kadar alkohol 20-55% (misalnya wiski dan brendi. ) Dalam melakukan pengujian kadar alkohol pada minuman BPOM tidak bisa mengetahui langsung kadar alkohol yang terkandung dalamnya. Minuman tersebut diuji di Laboratorium kemudian baru bisa diketahui apakah minuman tersebut layak beredar atau tidak. Proses uji Laboratorium membutuhkan waktu yang cukup lama, sehingga bagi para pedagang tidak bisa langsung mengetahui apakah minuman yang dia jual layak beredar atau tidak. Untuk mengatasi kendala efisien waktu dan tempat maka pada tugas akhir ini telah dibuat alat ukur kadar alkohol menggunakan mikrokontroller AT89S51. Perancangan dan pembuatan alat ukur kadar alkohol pada tugas akhir ini memakai sensor TGS822 untuk menditeksi kadar alkohol yang diproses oleh mikrokontroller AT89S52 keluaran Atmel dan ditampilkan oleh display LCD. Pengujian alat ukur ini dilakukan pada alkohol dengan sampel yang berpariasi dan mempunyai kesalahan pengukuran kadar alkohol sampai 3 persen. Penggunan sensor yang lebih baik dalam alat ukur kadar alkohol dapat memperkecil pengukuran.

The intensity of electrical energy consumption at the Denpasar District Court in 2020 is 133.84 kWh/m2/year. Based on the Minister of Energy and Mineral Resources Regulation No. 13 of 2010 on an air-conditioned building, the building is included in the wasteful category. So the Denpasar District Court office must make efforts to save money by conducting energy audits on lamps, coolers (AC), and other equipment. The purpose of this research is to analyze electrical energy opportunities and provide recommendations for savings that can be made. The method used in this research is descriptive quantitative by calculating the IKE of the building. The results of this study obtained the total energy needed in existing conditions (before the LED lamp and AC inverter were replaced) with the assumption that the lamp and air conditioner operated for 8 working hours per day and 24 days per month, the total energy was 140,101,344 kWh/year. Meanwhile, the total energy consumed after replacing the LED lamps and AC inverter is 124,328,448 kWh/year. So that there is a saving of 15,772,896 kWh of electrical energy for one year with a saving of electrical energy costs of Rp. 22,787,102.85 / year. IKE before replacing the LED lamps and AC Inverter is 41.462 kWh / m2 per year in the wasteful category according to the Ministerial Regulation ESDM No. 13 of 2012. Meanwhile, after replacing the LED lamps and AC inverter, the IKE obtained is 36,794 kWh/m2 per year in the wasteful category, but there are savings in electricity consumption and electricity payment costs.

The utilization of renewable energy is one of the solutions to overcome the increasing electricity demand. One of these solutions is to install Solar Power systems on the roofs of offices, industries, or households. This study targets to meet electricity demand by utilizing the roof of the Mega Dana Hotel as a place for the installation of solar panels, the solar panel will later produce electrical energy to meet the electricity needs of the hotel bars. The simulation results of the production of electric energy at Hotel Mega Dana's solar panel system using an application called Helioscope. This study analyzes the economics of designing a rooftop solar power system at Hotel Mega Dana. The feasibility of this research investment is assessed from the value of NPV, PI, and DPP. According to the data obtained, the Hotel Mega Dana building has a roof area of 655.92 m 2. The study used 39 solar panel modules, 1 20kW inverter, and 5 48V 100 Ah TLO batteries, the system can produce 17,6 kWp of power, with a total annual energy production of 21.83 MWh to supply electricity for the bar at Hotel Mega Dana. This research was planned with an initial capital of IDR 254,578,500, a PI value of 1.09, and a DPP value of 21.9 years. The results of this research analysis can be considered feasible because the design has a positive NPV value and is expected to return investment at 21.9 years out of 25-years project life.

Tracer Study digunakan sebagai media untuk mendapatkan informasi lulusan dan feedback atau timbal balik dari alumni mengenai proses pembelajaran di perguruan tinggi. Saat ini, sistem masih menggunakan google form untuk mendapatkan informasi mengenai alumni sehingga membutuhkan waktu yang cukup lama untuk mengelola data yang didapatkan, dan kemungkinan akan ada data yang terduplikasi atau data yang salah karena masih menggunakan sistem yang manual. Tracer Study ini dibangun untuk memecahkan masalah yang terjadi pada perguruan tinggi yang masih menggunakan sistem yang sederhana seperti google form untuk mendapatkan data alumni. Tracer Study dibuat dalam bentuk website yang digunakan untuk mengelola dan mengolah data yang didapat dari alumni, dan membuat pengumuman untuk informasi mengenai pengisian tracer study. Selain itu, sistem ini juga menggunakan bantuan virtual assistan seperti Telegram untuk menghubungkan alumni dengan administrator terkait dengan pengumuman dan pengisian Tracer Study oleh alumni. Tracer study berbasis website dengan virtual assistant ini diujikan menggunakan ISO 9126 dengan didapatkan hasil yang baik dari beberapa aspek pengujian serta diharapkan mampu membantu institusi dan mampu memudahkan menghubungi alumni dalam pengisian survey lulusan karena dapat dilakukan secara online.
