Abstract

Suatu sistem JaringanTegangan Rendah (JTR), ketidakseimbangan beban selalu terjadi. Hal ini disebabkan oleh tidak meratanya pemakaian beban satu fasa yang berasal dari peralatan listrik rumah tangga, yang pada akhirnya akan menyebabkan terjadinya rugi-rugi pada jaringan. Pemerataan beban tiap fasanya merupakan salah satu cara yang ditempuh untuk menekan rugi-rugi. Penelitian ini dilakukan dengan menganalisis rugi-rugi daya keadaan seimbang dan keadaan tidak seimbang pada waktu siang dan malam hari di JTR dan SR gardu distribusi DS 0587.Berdasarkan hasil analisis, adanya ketidakseimbangan beban pada JTR DS 0587 telah menyebabkan terjadinya rugi-rugi daya. Besar rugi-rugi daya beban seimbang pada siang hari sebesar 0,54 kW dengan persentase rugi-rugi sebesar 0,86%, dan waktu malam hari sebesar 1,2 kW dengan persentase rugi-rugi sebesar 1,48%. Sedangkan rugi-rugi untuk beban tidak se-imbang waktu siang hari sebesar 0,66 kW dengan persentase rugi-rugi sebesar 1,06%, dan waktu malam hari sebesar 1,46 kW dengan persentase rugi-rugi sebesar 1,8%.Jadi semakin besar persentase ketidakseimbangan beban pada suatu jaringan distribusi tenaga listrik, maka akan semakin besar pula rugi-rugi yang ditimbulkannya.

Abstract

Beban tidak seimbang pada instalasi listrik selalu terjadi dan penyebab beban tidak seimbang dipengaruhi oleh banyak factor diantaranya pembagian beban antara fasa (fasa R,fasa S,dan fasa T) yang tidak seimbang. Akibat pembagian beban yang tidak seimbang pada masing-masing fasa tersebut mengalir arus di netral pada fasa N. Akibat arus yang mengalir di fasa netral ini menyebabkan terjadinya losses (rugi-rugi). Penelitian ini dilakukan dengan mengitung rugi-rugi daya beban seimbang dan beban tidak seimbang pada waktu malam hari di kampus Fakultas Teknik Universitas Udayana Jalan PB.Sudirman Denpasar. Berdasarkan hasil perhitungan adanya beban tidak seimbangan beban antara fasa pada MDP1 dan MDP2 telah menyebabkan terjadinya rugi-rugi daya. Besar rugi-rugi daya beban seimbang pada MDP1 sebesar 0,042 kW, dan beban tidak seimbang sebesar 0,055 kW. Sedangkan rugi-rugi untuk beban seimbang MDP2 sebesar 0,28 kW, dan beban tidak seimbang MDP2 sebesar 0,35 kW. Jadi semakin besar beban tidak seimbang yang mengalir beban pada suatu instalasi listrik, maka arus yang mengalir pada fasa netral juga besar, dan losses akibat arus netral yang mengalir ke tanah semakin besar pula.

Abstract

The limited availability of fossil fuel reserves and the fact that their formation takes millions of years have driven the accelerated adoption of electric vehicles as a strategic step to reduce carbon emissions. Bali, as one of the leading regions in the clean energy transition, requires adequate infrastructure support, particularly charging stations as the main facilities for electric vehicles, whose development must take into account proper location selection and design. This study focuses on the design and location selection of battery swapping stations for electric motorcycles (SPBKLU) in South Bali, including three-dimensional designs and electrical layouts, as well as location determination using the Analytical Hierarchy Process (AHP) method by evaluating potential sites. The results of this study are one optimal location for SPBKLU installation, accompanied by a three-dimensional design suited to the site’s characteristics and the SPBKLU’s electrical layout. In the future, it is expected to serve as a study and reference for the development of electric vehicle infrastructure in Bali, accelerating public adaptation to this technology.

Abstract

Indonesia is currently in a transition toward clean energy. Therefore, accelerating the adoption of Electric Vehicles (EVs) as a replacement for fossil-fueled vehicles has become a strategic step that is being actively promoted. To support this, the availability of adequate infrastructure is a key factor, with charging stations serving as the main infrastructure for electric vehicles. For optimal operation, the development of charging stations requires proper location selection and design. This study focuses on the design and location selection of Public Electric Vehicle Charging Stations (SPKLU) intended for electric motorcycles in the South Bali region. The design features a three-dimensional model of the charging station, along with its corresponding electrical plan. Meanwhile, location selection is carried out using the Analytical Hierarchy Process (AHP) method by evaluating potential sites. The outcome of this study is the identification of the best location for installing the SPKLU, accompanied by design suited to the site’s characteristics and the SPKLU’s electrical design. It is expected that this work can serve as a study and reference for further development to accelerate the adoption of electric vehicles in Bali.

Abstract

Bali is one of the regions in Indonesia at the forefront of the transition toward clean energy. One of the key steps to achieving this goal is the shift to electric vehicles (EVs). Therefore, the design of electric vehicle charging stations is a crucial factor in ensuring a smooth transition. Charging stations must be strategically located to provide easy access for users, and their planning must comply with existing regulations. One type of charging station is the Public Electric Vehicle Charging Station (SPKLU). However, most SPKLUs are focused on electric cars, whereas the use of electric motorcycles is far more widespread. For this reason, this study focuses on the design of a direct charging system for electric motorcycles, which can be connected directly to the vehicles. The design process includes both 3D modeling and the electrical layout. The selection of a suitable location will be carried out using the Analytic Hierarchy Process (AHP) to determine the optimal site in the South Bali area

Abstract

Bali Province is one of the areas that has abundant renewable energy potential. Through increasing the role of renewable energy in the national energy mix which is a government program, which aims to reduce the use of non-renewable energy and open community participation in utilizing renewable energy in Bali Province. To overcome these problems, an analysis of the investment costs of developing renewable energy plants in Bali Province in 3 scenario modeling was carried out. In this scenario modeling is carried out to determine the investment cost of developing renewable energy plants in Bali Province in the 2024 - 2045 time span. The results of this study show that renewable energy investment costs in the optimistic scenario require investment costs of 264,12 Million USD in 2024 increasing to 2.078,35 Million USD in 2045 with total investment costs during the modeling period of 46.477,10 Million USD. The moderate scenario requires investment costs of 264,12 Million USD in 2024 increasing to 1.186,30 Million USD in 2045 with total investment costs during the modeling period of 27.362,52 Million USD. The pessimistic scenario requires investment costs of 264,12 Million USD in 2024 increasing to 986,80 Million USD in 2045 with total investment costs for the modeling period of 20.817,04 Million USD.
