Water purification is carried out to separate water from minerals in it. One process of water purification is distillation. Water destilator require heat that can be obtained from electricity. The Gunung Sawur 1 Microhydro produces electricity for the surrounding society. But, not all electricity produced by microhydro was used. Excess of electricity from microhydro discharged into dummy load for balancing. The potency of wasted electrical energy can be used for water distillation. The purpose of this research were to make a plan about water purification using wasted electrical energy from microhydro Gunung Sawur 1 and investigate its economic feasibility. This research begun with a survey of potency of wasted electrical energy in microhydro Gunung Sawur 1. The potency of waste electrical energy as the basic to calculate the production capacity of water distillation column. Feasibility study was carried out by using NPV and B/C ratio. The result showed that the potency of wasted electrical energy in microhydro of Gunung Sawur 1 up to 66 kwh/day. The capacity of maximum power of planned distillation column was equal to the maximum power of microhydro dummy load. The production capacity of pure water was about 66 liters a day. The production of water purifier was feasible to do based on NPV value of IDR 30,121,094 and the B/C ratio value of 1.51. Keywords: distillation, microhydro, wasted energy

Building Information

Buildings contribute more than 40% of world energy consumption, so it is feared that it will cause energy problems in thefuture, especially in the construction sector. One solution to reducing this problem is by analyzing energy use at the initialdesign stage and utilizing solar energy as one of the solar power plants (PLTS) in office buildings. To analyze the use ofenergy in buildings, Building Information Modeling (BIM) was used. The purpose of this research is to analyze the annualenergy level of office buildings in Palembang using BIM software, namely Autodesk Revit. The number of solar panels aswell as the amount of energy were also identified using web-based software (HelioScope) resulting the economic feasibilityas indicated by the installation of solar panels as a component of PV mini-grid. The results showed that the use of BIMtechnology in analyzing building energy can provide a detailed description of the building model at the design stage. Revitanalysis indicates that the building consumed electrical energy per year for about 3,647,713 kWh with a roof area of 1,657m2. In addition, based on the HelioScope analysis, the use of renewable energy from the installation of PLTS was 152,900kWh/year. Meanwhile, for economic feasibility analysis, the installation of PLTS in office buildings can provide a positive NetPresent Value (NPV), indicating a feasible project.

Power management systems (PMSs) are essential for the practical use of microbial fuel cell (MFC) technology, as they replace the unstable stacking of MFCs with step-up voltage conversion. Maximum-power extraction technology could improve the power output of MFCs; however, owing to the power consumption of the PMS operation, the maximum-power extraction point cannot deliver maximum power to the application load. This study proposes a practical power extraction for single MFCs, which reserves more electrical energy for an application load than conventional maximum power-point tracking (MPPT). When experimentally validated on a real MFC, the proposed method delivered higher output power during a longer PMS operation time than MPPT. The maximum power delivery enables more effective power conditioning of various micro-energy harvesting systems.

The world is demanding for alternative way of energy consumption for vehicle usage. The energy efficient vehicle (EEV) is one of the advancement for future land transportation that known as hybrid and electric vehicles nowadays. The vehicles use different energy other than fuel which is electric energy. This paper emphasizes the development of electromagnetic energy regenerative suspension system (EReSS) as a system that harvests energy from the vibration of vehicle suspension system. The harvested energy is converted to electrical energy for vehicle usage. A prototype of electromagnetic EReSS is fabricated and laboratory experimentation on test rig is conducted to test the voltage output. It is observed that the EReSS can harvest the wasted energy from the vibration and produce sufficient electric energy for the vehicle electrical and electronic usage. The number of windings of the coil and diameter of the coil affect the voltage output of the EReSS. The voltage output of the EReSS can be optimized by setting up the parameters. As the EReSS is proven to harvest energy, it can be used on hybrid and electric vehicle to improve the efficiency of the vehicle and reduce the fuel consumption.

Water is the primary source needed to ensure human and other creature life continuity. There are a lot of water on this planet, but increasingly this water is not where it is needed or it is of inadequate quality (purity) for human consumption or other beneficial for example industrial, agricultural and so on purposes. Contaminated water supply causing harm to human body health and also contributes to extinction to the certain creature. Thus, water-saving or wise water usage is an important matter in Islam. Reuse of wastewater or sewage water is a solution to the water crisis problem faced nowadays. The contaminated water is purified and treated by certain processes. Water purification or treatment water is introduced to produce pure and clean water. However, discussions and debates among experts and societies continue to occur because the water is categorised as pure water but not purify (musta'mal) and impure water and not purify (mutanajjis). Therefore, this study aims to identify the concept and method of water purification and treatment (تطهير الماء) according to Fiqh perspective. Methodology of this study is qualitative approach by using document analysis by analysing several classic Fiqh books by four mazhab (Hanafi, Maliki, Shafie and Hanbali). Hence, this study can discover the water purification method suggested in Fiqh perspective to be applied by Muslim communities in Malaysia.

The need for electrical energy continues to increase every time. Concerns about the depletion of fossil energy reserves encourage the acceleration of the development of renewable energy use. One of renewable energy is the solar energy. Due to the irreversible irradiation conditions, it takes controls to keep the solar panel's maximum power. The most widely in Maximum Power Point Tracking (MMPT) is Perturb Algorithm and Observe (P&O) but P&O Algorithm has deficiency of oscillations when steady state and MPP trace errors when irradiation changes rapidly. In this paper proposed P & O-Fuzzy algorithm is a modification of conventional P & O to improve the efficiency of solar panels. This research uses Matlab for simulation and hardware implementation using microcontroller Arduino Uno and buck converter topology. The result of simulation and hardware implementation, conventional P & O has an average efficiency of 85.03% while MPPT modification with P & O-Fuzzy algorithm can improve MPP tracking efficiency with 89.67%.

The solar energy being clean, green & commercially modest, have become one of the most prevalent choice amongst the renewable sources of electrical energy. Utilization of energy generated from Solar photovoltaic (SPV) system rest on the maximum extraction of the power generated. Ideal maximum power point (MPP) tracking (MPPT) is used to transfer 100% generated power from source and transfer it to load. In literature of recent years, a good number of publications found on SPV systems and MPPT. In this paper most popular MPPT techniquesPerturb & Observe (PO) and Incremental Conductance (IC) methods are simulated and implemented. The comparison is also presented on the ground of parameters like tracking time, tracking efficiency etc.
