Abstract

Pengembangan sumber energi terbarukan, terutama pembangkit listrik tenaga angin dan surya sangat penting di Indonesia. Hal ini disebabkan kedua jenis pembangkit tersebut dinilai paling potensial dan realistis untuk mendukung program pengembangan energi terbarukan di Indonesia. Dalam penelitian ini disajikan studi tentang indeks keandalan pembangkit listrik hibrid tenaga angin dan surya. Metode untuk menganalisis indeks keandalan adalah metode EENS (expected energy not supplied). Dalam penelitian ini dilakukan analisis lapangan pada pembangkit listrik yang telah beroperasi di Kabupaten Bantul Provinsi Daerah Istimewa Yogyakarta. Hasil penelitian menunjukkan bahwa nilai EENS masih belum memenuhi standar yaitu 0,002% per tahun. Studi yang dilakukan pada tahun 2019 ini menyimpulkan bahwa pembangkit listrik hibrid berbasis tenaga angin dan surya ini belum dapat diandalkan untuk mendukung ketersediaan energi listrik di wilayah Bantul.    The development of renewable energy sources, especially wind and solar power plants, is very important in Indonesia. This fact is because these two types of power plants are considered the most potential and realistic to support renewable energy development programs in Indonesia. In this research, a study on the reliability index of wind and solar-based power plants is presented. The method for analyzing the reliability index is the EENS (expected energy not supplied) method. This study conducted a field analysis on a power plant that has been operated in Bantul district, Yogyakarta Special Region province. The results of the study show that the EENS value still does not meet the standard, namely 0.002% per year. The study conducted in 2019 concluded that wind and solar-based hybrid power plants could not be relied on to support the availability of electrical energy in the Bantul area.

Abstract

Development of waste-to-energy plant is regarded as one of a solution to reduce fossil energy dependency and switch to another alternative energy sources, thus needs to be implemented immediately. Research on the potential of organic waste by taking case studies at UMY green campus program can be an illustration that in the future UMY can process this potential into an alternative renewable energy. This research was conducted by studying waste management and data collection methods, such as field observations, discussions with related parties about the waste cycle, and calculations with the concept of gasification. Calculation of biomass produced by organic waste is then supplied to the motor generator for electricity production. Annually, 31.8 tons of organic waste could produce 7.9 kiloliters of biomass and channel it to the power plant system for generating electricity energy as much as 5.3 MWh per year. This number equals to the electricity supply of five small-housing in Indonesian typical house.

Abstract

This paper discusses an interface data acquisition (DAQ) of a rocket using LabVIEW. The software development is meant to improve the quality and reliability of the interface that has been built by the UMY rocket team. The data used on the experiments is a set of dummy data created for simulation purpose. This data is generated by Arduino UNO, in which it was acquired by LabVIEW through VISA serial communication platform. The test results show that there is 10% error during the data retrieval. The DAQ average speed is 270 milliseconds. This new approach has more stable and reliable system when compared to previous algorithm.

Abstract

Reliability of distribution networks is a factor that greatly affects customers as consumers of electricity. Analyzing and calculating the reliability of distribution networks are determined by the reliability index including SAIFI, SAIDI, CAIDI, and ASAI. On the other hand, smartphone technology is growing rapidly with a variety of applications to help simplify and accelerate human work in several fields of work. This paper delivers the design of an Android-phone-based analytic tool for distribution system reliability index measurement by developing it on Android application software. This application is named KALINDA, stands for Kalkulator Indeks Keandalan (Reliability Index Calculator), and created by using Android Studio IDE. We compare the data result between KALINDA calculations and manual calculations. The results obtained from the KALINDA application are declared to be valid accurate.

Abstract

Along with technological advances, it is estimated that the gross regional domestic product (GRDP) of Kulon Progo Regency increases annually by 7.6%, and the population growth of Kulon Progo regency increases annually by 0.9%. However, after assuming with Muara Bungo Regency as a reference to GRDP growth and Population of Kulon Progo Regency due to the influence of the Establishment of New Yogyakarta International Airport (NYIA) in 2019, the population growth every year is 15.78%. While GRDP in 2018 until 2019 equals to 82.91% and next year equals to 7.6 %. Load forecasting the burden for the next ten years by using multiple linear regression affected by NYIA in 2019, the loading of the 150 kV Wates substation is only up to 2021 for the power transformer I of 24.83 MW and the power transformer II 55.40 MW. So it is estimated that for 2022, power transformer I and power transformer II of 150 kV Wates Substation are no longer able to serve the loading. Then, in 2021 a feeder shift and uprating power transformer I need to be conducted. In 2024 a power transformer III is needed. In that year the feed formation from power transformer I and power transformer II was changed to power transformer III.

Abstract

This work reports the implementation of using energy efficient electronic devices to reduce the electricity consumption in Universitas Muhammadiyah Yogyakarta (UMY). The first step taken by UMY is to replace lighting and cooling system in all its rooms using energy saving devices. This research was conducted in building E4. This research was conducted by surveying the designated building to get data about lighting and air conditioner devices used in the E4 building. If the proposed concept is applied to lighting and cooling system, UMY would be able to reduce electricity consumption by 28.1 MWh, and this can support the breakthrough of turning UMY into a green campus.
