Tanki penampung air hujan (PAH) dibuat masyarakat digunakan untuk memenuhi kebutuhan air sehari-hari. Saat kemarau dan persediaan pada tanki PAH telah habis, maka air harus dibeli dari distributor seharga Rp 100.000,- per Tangki dengan volume 4000 liter. Bagi yang tidak mampu, mereka harus mengambil dari sumber air Sureng yang berjarak 2 km. Sistem pengangkatan air tenaga surya dalam penelitian ini dirancang untuk menggantikan peran kedua pompa yang telah ada pada sistem pemipaan di Sureng (saat ini digerakan oleh mesin genset) yakni memompa air dari sumber air sampai ke Penampung Air Umum dengan debit 0,9 L/s dengan memanfaatkan jaringan pipa yang telah ada. Sistem menggunakan 2 kali pemompaan, pemompaan pertama berfungsi untuk memompa air dari sumber ke reservoir atas bukit dengan head total 105,79 m.

Battery Electric Vehicle (BEV) is one of the alternatives to reduce oil consumption and CO2 emission on the road transportation sector. This research is carried to analyse impact on BEV on energy demand and carbon emission. Modified Mobility Model (MoMo) with PUCE methods was developed to projecting road transportation demand in Indonesia. This research shows that road transportation will reach 519 MBoe in 2040 with 83.6% from refined fuel oil. With moderate EV, energy will be reduced by 31 MBoe (6%), and refined fuel oil reduced by 8.5%. With a high EV scenario, energy will be reduced by 57 MBoe (14%) and refined fuel oil reduced by 16%. CO2 emission will be reduced up to 4.8 to 8.8% in 2040.

The use of electrical energy is still not resolved in this case because of the lack of appropriate policies that can be taken because there is still no research how the amount of electrical energy consumption in Aceh Tamiang. the research method used is a model based approach to End Use of data population and households, the data GDP at constant prices, and consumption of electrical energy. All data is sourced from related agencies such as Bappeda Aceh Tamiang Data PLN Kuala Simpang branch. Forecasting electric energy consumption in Aceh on five sectors is the year 2013 was 48.8 GWh, while, in 2030 total energy consumption reached 76.5 GWh, this is an increase of 63.7 percent. The household sector accounted for the largest increase in consumption compared with other sectors for each year.

The 12 kWp solar PV and 30 kW generator were used to power the standing-aline system.. Unfortunately, the system has been idle since 2010. Research to redesign and analyse solar water pumping system has been conducted by Ministry of Public Works together with the Department of Physics Engineering UGM to bring it into normally. Furthermore, this study was aimed to obtain recommendation and to conduct analysis on system performance using HOMER. As a result in deferrable-load method, generator is inappropriate to be implemented because fossil fuel will be very expensive and rare. Besides, the 12 kWp Solar PV could meet 31.4 % of demand load. In primary-load method, capacity shortage of 1.5 kW pump is at 3.2 % and 3 kW pump is at 9.9 % which means that to deal with fluctuation of solar radiation th...

One of remote area in Indonesia that has ever used both systems in water pumping system is Purwodadi Village, Tepus district located at karsts area of Gunungkidul. The economical comparison between both technologies will be analyzed using lifecycle cost calculation and HOMER simulation. The analysis shows that using photovoltaic for water pumping system only spend 3/4 times of diesel generator cost. On the other hand, HOMER analysis shows that the cost of energy value for photovoltaic usage is 0.

There are three micro hydro power systems in operation today, namely Pancuang Taba (40 kW); Muaro Air (30 kW); and Koto Ranah (30 kW). The Water Evaluation and Planning (WEAP) system was applied to simulate hydrological model and micro hydro power projection under different scenarios of greenhouse gas emissions (A2 and B2) from IPCC reports. The model was performed for the 2013-2025 period. Results demonstrated that climate change will reduce micro hydro power production. Changes in power generation were varying up to 7.6 % under B2 scenario and up to 15.7 % under A2 scenario at the last projection year.
