Abstract

Microgrid systems are part of the most reliable energy supply technologies for rural communities that do not have access to electricity but the system is generally dominated by diesel generators (DG). The implementation of de-dieselization programs to ensure efficient diesel operations requires addressing several scenarios such as the replacement of diesel completely with 100% renewable energy sources at a significant cost. The design and selection of appropriate configuration, as well as operating patterns, need to be considered in adopting economical and reliable microgrid systems. Therefore, this study aimed to design an optimal configuration and operational pattern for microgrid systems for the frontier, outermost, and least developed (3T) regions using Baron Techno Park (BTP) in Indonesia as a case study. The optimization was conducted through HOMER software combined with benefit-cost analysis and the focus was on daily load variations, selection of control algorithms, reconfiguration of the power supply system, and setting of the diesel generator operating hours. The results showed that the optimum configuration was achieved using loads of resort, 24 kWp of PV, 288 kWh of BESS, load-following (LF) as dispatch controller, and 25 kVa of DG. Moreover, the proposed microgrid system produced 12% excess energy, 36% renewable fraction (RF), 13.25 tons reduction in CO2 emissions per year, $0.28 LCOE per kWh, $250,478 NPC, and a benefit-cost ratio (BCR) of 0.89. It also had a potential energy efficiency savings of 55.56% and a cost efficiency of 20.95% compared to existing system configurations. In conclusion, the study showed that the addition of DG to microgrid systems in 3T areas was more optimal than using only PV and batteries. An effective operating schedule for the DG was also necessary to improve RF and reduce expenses. Furthermore, other energy storage devices considered less expensive than batteries could be introduced to improve the economics of microgrid systems in the 3T region.

Abstract

PT Pionerbeton Indiustri is one of the companies engaged in the production of ready mix concrete, which is a subsidiary of PT Indocement Tunggal Perkasa, Tbk for casting projects located in JL. Ahmad yani (South Ringroad), Padukuhan Modalan RT 02, Banguntapan Village, Banguntapan District, Bantul Regency DIY. The method used in the study was to use the OMAX (Objective Matrix) method. This research was conducted for 12 months, namely January-December 2021. This research was conducted using the OMEX (Objecktive Matrix) method, so that in processing the data is carried out by following the steps of OMAX (Objecktive Matrix). The purpose of this study is to determine the ratios that most affect the rise and fall of productivity levels with the Objecktive Matrix method. Based on calculations using the Objecktive Matrix method, it shows that the productivity data of PT Pionirbeton Industri has a low value in September material, which is 471,134,817 due to the late supply of raw materials which results in decreased productivity in September.

Abstract

Makalah ini membahas tentang pengembangan aplikasi mobile untuk pengisian daya kendaraan listrik, yang diberi nama SONIKApp. SONIKApp digunakan untuk melakukan reservasi dan pengendalian pengisian daya secara remote. Fitur reservasi diperlukan mengingat pengisian daya baterai kendaraan listrik membutuhkan waktu tunggu serta masih terbatasnya stasiun pengisian kendaraan listrik umum (SPKLU) di Indonesia. Fitur pengisian daya berbasis remote juga merupakan fitur penting yang memungkinkan pengguna untuk mengendalikan proses pengisian daya kendaraan listrik. SONIKApp juga terhubung dengan sistem manajemen SPKLU berbasis standar OCPP 1.6 secara real-time sehingga data yang ada di aplikasi selalu merupakan data terkini. Aplikasi ini dikembangkan dengan kerangka kerja front-end React Native, sehingga dapat berjalan di atas sistem operasi Android dan iOS. Hasil yang diperoleh adalah terciptanya aplikasi mobile SONIKApp yang memudahkan pengguna dalam pengisian daya kendaraan listrik. Telah dilakukan pengujian SONIKApp untuk fitur reservasi dan pengisian daya secara remote berdasarkan OCPP 1.6, dan hasilnya adalah aplikasi SONIKApp telah berhasil mengimplementasikan fitur-fitur tersebut. Abstract This paper discusses the development of a mobile application for charging electric vehicles, which is named SONIKApp. SONIKApp is used to make reservations and control charging remotely. The reservation feature is required considering that charging electric vehicle batteries requires waiting time and there are still inadequate number of public electric vehicle charging stations (SPKLU) available in Indonesia. The remote-based charging feature is also an important that allows users to control the process of charging electric vehicles from the applications. SONIKApp is also connected in real-time to the SPKLU management system based on the OCPP 1.6 standard so that the data presented in the application is always up-to-date. This application is developed with the React Native front-end framework, so it can run on both Android and iOS operating systems. We have successfully created the SONIKApp mobile application which makes it easier for users to charge electric vehicles. SONIKApp has been tested for reservation and remote charging features based on OCPP 1.6, and the result is that the SONIKApp application has successfully implemented these features.
