Ab.f/racl-·Malaysia has considerahle number of widely deployed small rural areas. These hamlets are ver y much associated with the aborigines' or better known as 'Orang Asli' residents. Normally they get their source of energy from candle or kerosene light while some richer communities can afford generator sets.Conservatively, solar photovoltale systems are installed as standalone system to provide basic electricity to each aborigines home. On the other hand, for this project, a pilot centralized solar power station was Installed to provide electricity to fifteen houses at a small village east of Malaysia.This system Is the first solar photovoltalc system Installed at the 'Orang Asll' village In Mlllllyslll.This system will be the first ever built for the orang IIsli settlement at Pllhang.The objectives of this project lire to design and install the solar power stllUon lit remote location and to develop standard design of stand·alone solar power stillion sultllble for Maillysia.Orang Asli residents at Kampung Denai was chosen because there Is a school for the Orang AslI children. Moreover, the remote communities lire living in strlltil1clltion, which makes electrical wiring easier. Furthermore, the remote area Is far from the rast Irllnsmlulon line And cumbersome to bring diesel through the rough and unpredictable land road.The milin domestic energy 11 for residential purposes (e.g.small lighting unit, radio, television, video, etc.).

Keywords-solar photovoltaic, 'orang IISI1' and solar hybrid power station I. INTRODUCTION T NB has been involved with solar since the 1980s. At that time, most solar projects undertaken by TNB in Peninsular Malaysia were associated with decentralized stand-alone system for the Rural Electrification Program. As it is very expensive to provide electricity supply from the grid to the rural area, stand-alone solar PV systems were recognized as a cost-effective option to electrify the remote villages Building this solar power station will contribute to fulfill the Eight Malaysian Plan that is to supply about 5% of the electrical energy through the application of the 0-7803-8208-0103/$17.00 ©2003 IEEE. renewable sources of energy. In crises where such comillunities me widely scattered. having small loads and remote and far away rrom the unified grid, solar energy can play an important role tn their socio-economic development.

Electricity-saving can be achieved through the efficient use of energy such as turning off lights and electrical appliances when not in use. Therefore this work proposed the smart classroom for electricity-saving with an integrated IoT System to prevent wasting electricity in the classroom. Smart Classroom means that it will detect and count the number of students entering and exiting the classroom by using a sensor system automatically. The main objective of this work is to control the lighting systems and fans by using the IoT application and sensor system. This means that when the sensor is triggered the sensor will send data to the Blynk application software using IoT to display the status of the classroom. This proposed work is also able to detect whether a classroom is available to use or not based on the presence of people. If the classroom is being used the Blynk application software will show the lamp and fan are ON. Otherwise the lamps and fans are OFF if there are no people in the classroom. The result successfully shows that if the first student entering the classroom all the lamps and fans are ON. While if the last student exiting the classroom all the lamps and fans are OFF. This result also indicates that electricity can be saved if all appliances in the classroom are switch OFF at the right time.
