Konsumsi energi listrik di Aceh semakin meningkat dari tahun ke tahun.Faktor yang menyebabkan meningkatnya konsumsi energi listrik di Aceh adalah Pertumbuhan Penduduk, dan Ekonomi. Untuk memenuhi akan kebutuhan konsumsi energi listrik yang semakin meningkat dari tahun ke tahun, maka dilakukan perkirakan konsumsi energi listrik jangka panjang selama 10 tahun yaitu pada tahun 2028 di Aceh. Untuk memperkirakan konsumsi energi listrik ini memerlukan sebuah metode yang dapat mendekati hasil aslinya.Metode tersebut yaitu Metode Adaptive Neuro Fuzzy Inference System. Hasil yang didapat dalam memperkirakan konsumsi energi listrik pada tahun 2028 di Aceh dengan menggunakan metode ini adalah sebesar 5578,02 GWh atau dengan kenaikan 2,07% setiap tahunnya sampai tahun 2028.

In the present study, two sets of bionanopolymeric alumina and bionanopolymeric silica content samples were prepared. To each sample, the nano alumina particles with a weight percentage of 1.5%, 3%, 4.5% and 6% were added. To investigate the effect of nanoalumina and nanosilica filler to the mechanical properties of these nanocomposites materials, the tensile test had been carried out. The results show that the tensile strength of two groups of sampless decrease constantly with the increasing of weight percentage of nanofillers.

Agriculture is one of the main sectors in Karo Regency, North Sumatra. One of the commodities produced by farmers in Karo Regency is carrot. The inability of farmers to control soil moisture may cause crop damage to a lack of productivity. This research aims to create a monitoring & control system that is integrated with the website to make it easier for farmers to prevent problems that occur. The method used in the research is the design, installation, monitoring, and deactivation. The results obtained from this research are that farmers can now monitor the field conditions in real-time using a web-based monitoring & control system.

A wireless power transfer (WPT) system transfers an alternating current (AC) power from a TC (transmitter coil) to a RC (receiver coil), using an electromagnetic field concept. Several previous reports on WPT systems were able to transmit this power, although their AC frequencies were high in some kilohertz or megahertz (kHz or MHz). These frequencies were unable to be applied directly on the AC loads or only administered to the direct current (DC) energy after rectification through a rectifier circuit. In the receiver phase, the AC power was also very low, due to the minimum voltage and current on the RC. Therefore, this study aims to determine the effects of temperature and solar irradiance on the performance of the 50 Hz photovoltaic wireless power transfer (PVWPT) system. This system is constructed by some PV modules in series connection, to achieve a required DC voltage level on the DC-DC converter and receiver phase. It also converts DC to AC voltages on the TC (transmitter coil) of an H-bridge inverter, with a receiver circuit and a magnetic relay coil positioned between the TC and RC (transmitter and receiver coil). The results showed that solar irradiance and temperature affected the performances of the PV module and PVWPT system. This indicated that higher solar irradiance increased the performance of the PVWPT system, whose maximum efficiency was achieved by positioning the magnetic relay coil between the TC and RC.
