No full textThis paper presents a Hopfield neural network (HNN) optimized fuzzy logic controller (FLC) for maximum power point tracking in photovoltaic (PV) systems. In the proposed method, HNN is utilized to automatically tune the FLC membership functions instead of adopting the trial-and-error approach. As in any fuzzy system, initial tuning parameters are extracted from expert knowledge using an improved model of a PV module under varying solar radiation, temperature, and load conditions. The linguistic variables for FLC are derived from, traditional perturbation and observation method. Simulation results showed that the proposed optimized FLC provides fast and accurate tracking of the PV maximum power point under varying operating conditions compared to that of the manually tuned FLC using trial and error

No full textThe relationship of cement consumption and economic growth : an updated approach
No full textPurpose: This research aims to make an update how much volume of cement is needed for Indonesia, to disclose cement consumption for Indonesia and the relationship between cement consumption and several variables as inflators that influence cement consumption. Design/methodology/approach: The methodology used is regression analysis and descriptive analytics. The data period taken is primarily within the period of 2010-2018, but cement consumption and other variable inflators have been assessed within a longer period of 2007-2018. Findings: The findings are that national economic growth as inflator for cement consumption is no longer proven as by nature to develop robust models but must access of more than one predictor. Based on findings, by calculating cement consumption based on real consumption at every project are better than rely-on national economic growth. Practical implications: The recent model of cement consumption has been no longer as the inflator of economic growth and vice versa. An update for the cement consumption is urgently needed. Economic growth is no longer a predominantly inflator for the cement consumption. There is no obligation to consume more cements in purposing to drive economic growth. Originality/value: This research has been developed by the author from yearly observations and experiences at the cement sector in Indonesia.peer-reviewe
Perancangan Game Edukasi Pengenalan Sistem Tata Surya Sebagai Media Pembelajaran Berbasis Mobile (android) Menggunakan Unity
No full textThe solar system is one of the natural science subject material. This material studies the arrangement of planets or celestial bodies around the sun as the center. Solar system learning material is generally studied by children or students at elementary school level. However, at school the methods taught were still conventional and time was very limited. On this basis, the author intends to design an educational game regarding solar system learning material. The game created is an Androidbased game and will be developed using the Unity game engine. The role of this game aims to create learning media using fun digital methods so that children or students can learn and be entertaine
