Development of Energy Monitoring System at Green School Bali


During my undergraduate degree, I wrote a thesis about " Development of the Current Measurement System for Energy Monitoring based on Internet of Things (IoT) at Green School Bali, Indonesia". This project was also related to the Operation Rain or Shine (Renewable Energy Project at Green School Bali) that will be explained on the other post. For more information about the energy monitoring system, please visit my paper in the following link.

ASTECHNOVA PAPER
ABSTRACT
The hardware

Green School Bali, an international school which provides education for sustainability through entrepreneurial learning and natural environment won the Zayed Future Energy Prize for developing the new renewable energy projects. Currently, Green School is supported by 2 main power sources which come from Indonesian State Electricity Company (PLN) and Photovoltaics (PV) system electricity with power reach 23.1 kW and 21.6 kW respectively. Both of the sources are distributed to the load based on the manual balancing and daily manual switching, which create the unbalanced load and high power loss. The key to achieving sustainable energy management is the availability of accurate measurement, recording, and analysis system of the power quality in the whole buildings. To meet the requirement of the sustainable energy management system at Green School, the monitoring system of the power quality at Green School is developed. This system contains 2 data loggers and an Internet of Things (IoT) platform. The fixed data logger provides routine measurement and recording of power quality at the PLN meter, whereas the portable data logger provides the same function for each electricity panel. The monitoring and human interface system integrate the intelligent human machine interface to an Ubidots platform with online and offline data storage. This system is useful for supporting the sustainable energy management goal of Green School and the daily energy practitioner’s work providing a proper advance power quality monitoring system that has low cost and compatible with Green School system’s demand. This design and data monitoring project will also be used as a platform and teaching tool for students to develop similar projects and learn about IoT and cloud based monitoring solutions with other measures in the classroom. 
Keywords—Green School Bali, Human Machine Interface, Internet of Things, Power Monitoring System, Sustainable Energy Management System

Motivations and Expectations of Study at Electric Power Engineering KTH

This essay was made for Sustainable Electric Power Engineer assignment at KTH           Coming from Indonesia, an archipelago country with more than 17,000 islands, I see different challenges on electricity generations and distributions faced by my country. Indonesia has achieved a 98.86% electrification ratio since 2019, but regional disparities of electricity access are still happening. Many electrified regions, especially in Eastern Indonesia, have not had access to 24 hours electricity [1]; this impedes the development of other sectors such as economic, education, or health.  Therefore, I am motivated to pursue a career in the energy sector to take part in improving the life quality of many Indonesian citizens by providing more reliable energy access for society. By studying in the Electric Power Engineering [2] program in KTH, I wish to have a solid understanding of the electrical system, its operation and planning that will be beneficial to dev...

Cerita di Bawah Langit Senja Pulau Nyamuk

Pernahkah engkau melihat hamparan laut biru yang begitu luas dengan kerlap-kerlip airnya terpapar sinar matahari ? Bagaikan kristal-kristal permata biru yang begitu indah, gemericik arus laut dengan ombak yang begitu tenang telah membuatku jatuh cinta pada lautan ini saat pertama kali menaiki kapal dari Pulau Karimunjawa menuju Pulau Nyamuk. Bisa dibilang ini adalah pengalaman pertama bagi saya menaiki kapal kecil untuk membelah lautan, tak urung para perempuan anggota Tim KKN Pulau Nyamuk menjerit-jerit dalam perjalanan setiap kali kapal mengalami guncangan-guncangan yang belum biasa kami rasakan, meskipun pada akhirnya guncangan ombak telah menjadi hal yang biasa kami alami selama KKN di Pulau Nyamuk. Ketika kapal yang engkau tumpangi semakin mendekati Pulau Nyamuk, maka akan bisa dilihat lautan dangkal yang begitu bening dan bersih. Dan dapatkah anda lihat, ikan-ikan karang warna-warni yang seolah-olah melompat di antara rerumputan dan karang, anemon laut yang melambai-lambai...
